Description

APPAREIL DE REMORQUAGE DE VEHICULE AUTOMOBILE  TOWING APPARATUS FOR A MOTOR VEHICLE
Domaine technique de l'invention Technical field of the invention
L'invention est relative à un appareil destiné à charger un véhicule automobile immobilisé ou accidenté sur une chenillette motorisée, les mécanismes de mobilisation du véhicule étant agencés sur cette chenillette, de sorte qu'une fois le véhicule chargé, la chenillette peut se déplacer pour évacuer directement le véhicule, soit l'ensemble chenillette avec véhicule chargé peut monter sans assistance sur un camion plateau non basculant, soit la chenillette peut tracter un véhicule roulant. The invention relates to an apparatus for charging a motor vehicle immobilized or accident on a motorized track, the mobilization mechanisms of the vehicle being arranged on this track, so that once the vehicle loaded, the track can move for evacuate the vehicle directly, either the trailer with loaded vehicle can climb unassisted on a truck flat tilt, or the crawler can tow a vehicle.
État de la technique State of the art
Un véhicule immobilisé par exemple pour être conduit en fourrière, nécessite pour être levé sans dommages, une dépanneuse légère 4/4 équipée d'un bras hydraulique, tel que décrit dans le brevet WO 2005/051832. Cette dépanneuse permet de soulever deux roues du véhicule, généralement les roues avant, puis, si le frein à main est actionné, ou une vitesse enclenchée, il convient d'équiper les deux autres roues de chariot à roulettes, tel que décrit par exemple dans le brevet FR 2769909. La dépanneuse peut ainsi rouler avec le véhicule immobilisé, à faible vitesse, et sur de courts trajets. Ce type d'intervention prend un temps non négligeable, pendant lequel la circulation alentour sera gênée, voire bloquée. A vehicle immobilized for example to be driven impound, requires to be lifted without damage, a light 4/4 tow truck equipped with a hydraulic arm, as described in patent WO 2005/051832. This tow truck can lift two wheels of the vehicle, usually the front wheels, then, if the parking brake is actuated, or a gear engaged, it is appropriate to equip the other two wheels of trolley with wheels, as described for example in patent FR 2769909. The tow truck can thus ride with the vehicle immobilized at low speed and on short trips. This type of intervention takes a significant time, during which the surrounding traffic will be hampered or blocked.
Le brevet WO 2005/051832 décrit en outre un bras télescopique installé en position repliée à l'arrière d'un véhicule de dépannage, se déployant tout d'abord de la verticale à l'horizontale, et disposant de bras articulés se déployant à leur tour en pivotant horizontalement sous les roues du véhicule. Ce mécanisme met en œuvre beaucoup de pièces et de vérins hydrauliques, et ne résout cependant pas les situations très courantes de véhicules devant être déplacés avec les roues bloquées, ou non roulantes car accidentées. The patent WO 2005/051832 also describes a telescopic arm installed in the folded position at the rear of a recovery vehicle, deploying firstly from the vertical to the horizontal, and having articulated arms deploying to their position. turn by swiveling horizontally under the wheels of the vehicle. This mechanism implements many parts and hydraulic cylinders, but does not solve the very common situations of vehicles to be moved with the wheels locked, or not rolling because accident.
Le seul cas favorable est lorsque le véhicule immobilisé est accessible, non accidenté, ce qui permet de libérer frein et vitesse, et donc de lever l'avant du véhicule et le tracter simplement sur les deux roues arrière. The only favorable case is when the immobilized vehicle is accessible, not accident, which allows to release brake and speed, and therefore to lift the front of the vehicle and simply tow on the two rear wheels.
Si le trajet est long, il faudra de toute façon procéder à un remorquage lourd, nécessitant un camion équipé d'un plateau basculant et d'une potence et treuil hydraulique. Un tel camion est beaucoup plus long qu'un engin 4/4, et ne peut accéder dans des rues étroites ou encombrées, ni dans des parkings souterrains. If the journey is long, it will in any case proceed to heavy towing, requiring a truck equipped with a tilting tray and a gallows and hydraulic winch. Such a truck is much longer than a 4/4 machine, and can not access in narrow or congested streets, or in underground car parks.
Un professionnel doit donc être équipé des deux types de dépanneuses, afin de satisfaire au maximum de situations. A professional must therefore be equipped with both types of tow trucks, in order to meet the maximum of situations.
Pour autant, certains remorquages sont encore impossibles avec ces engins, par exemple dans des parkings au plafond trop bas qui interdisent l'accès d'un 4/4 équipé d'un bras hydraulique. Le véhicule doit donc être sorti du parking avec des moyens très inadaptés, tels que transpalette ou chariot élévateur bas.  However, some tows are still impossible with these machines, for example in car parks too low ceiling that prohibit access to a 4/4 equipped with a hydraulic arm. The vehicle must be removed from the car park with very unsuitable means, such as a pallet truck or a low lift truck.
De plus, le stockage des véhicules immobilisés par exemple dans une fourrière, nécessite beaucoup d'espace, car chaque véhicule doit pouvoir être accessible à tout moment, ce qui génère de nombreux couloirs, dont la largeur est très importante à cause de l'encombrement du 4/4 et du véhicule qu'il tracte. Il s'en suit une très importante déperdition d'espace, et de son coût induit. In addition, the storage of immobilized vehicles for example in a pound, requires a lot of space, because each vehicle must be accessible at all times, which generates many corridors, the width is very important because of congestion 4/4 and the vehicle he tows. It follows a very significant loss of space, and its induced cost.
Le document GM 8005602 décrit un dispositif de remorquage destiné à réceptionner deux voitures. Le deuxième chariot est formé par une potence reliée à un câble pour soulever une deuxième voiture par l'avant en la tractant sur les roués arrière. Il ne s'agit donc pas d'un chariot en liaison avec un outil qui enserre les roues comme dans la présente invention. La potence présente un inconvénient pour le chargement de la première voiture sur le plateau. La potence doit être déplacée à l'arrière du plateau, et actionnée vers le sol dans une position aplatie pour permettre à la première voiture de rouler par-dessus. La potence sert donc uniquement à remorquer la deuxième voiture. Rien n'est décrit par quels moyens les déplacements sont réalisés, et comment le véhicule est tracté sur le chariot. GM 8005602 discloses a towing device for receiving two cars. The second carriage is formed by a stem connected to a cable to lift a second car from the front by pulling on the rear wheels. It is not therefore a linked wagon with a tool that grips the wheels as in the present invention. The stem has a disadvantage for the loading of the first car on the plateau. The stem must be moved to the rear of the deck, and driven to the ground in a flattened position to allow the first car to roll over. The stem is only used to tow the second car. Nothing is described by which means the movements are made, and how the vehicle is towed on the carriage.
Le document US 5730577 se rapporte à un dispositif de chargement et de déchargement de motos. US 5730577 relates to a device for loading and unloading motorcycles.
De tels dispositifs ne permettent pas de charger rapidement un véhicule sur une chenillette autonome motorisée, et à évacuer directement le véhicule soulevé ou chargé, pour le monter sur un camion plateau à rampes d'accès. Such devices do not allow to quickly load a vehicle on a motorized autonomous track, and to evacuate directly the vehicle lifted or loaded, to mount it on a platform truck with ramps.
En résumé, les systèmes connus actuels de remorquage de véhicules et les dispositifs les mettant en œuvre, présentent des inconvénients, que la présente invention se propose de corriger. In summary, the current known systems for towing vehicles and the devices implementing them have disadvantages which the present invention proposes to correct.
Objet de l'invention Object of the invention

Selon l'invention, l'appareil de remorquage comporte une chenillette autonome à traction hydraulique, et un support inclinable monté à basculement de bas en haut autour d'un axe horizontal en étant piloté par au moins un vérin, ledit support étant conformé selon une poutre permettant le roulement de deux chariots sur l'intérieur et l'extérieur de ladite poutre, lesdits charriots comprenant : According to the invention, the towing apparatus comprises a self-propelled track with hydraulic traction, and a tilting support mounted to tilt upwardly about a horizontal axis being driven by at least one jack, said support being shaped according to a beam allowing the rolling two carriages on the inside and outside of said beam, said carriages comprising:
- un premier chariot inférieur destiné à rouler le long du support jusqu'au sol, et à réceptionner les deux roues avant ou arrière du véhicule,  a first lower carriage intended to roll along the support to the ground, and to receive the two front or rear wheels of the vehicle,
un deuxième chariot extérieur susceptible de rouler à la fois le long du support et du premier chariot jusqu'au sol, ledit deuxième chariot étant en liaison avec un outil spécifique destiné à immobiliser ou à réceptionner les roues du véhicule,  a second outer carriage able to roll both along the support and the first carriage to the ground, said second carriage being in connection with a specific tool for immobilizing or receiving the wheels of the vehicle,
ledit outil étant formé par un mécanisme hydraulique à fourche équipé d'un premier cadre et d'un deuxième cadre réglables selon des directions orthogonales .  said tool being formed by a forked hydraulic mechanism equipped with a first frame and a second frame adjustable in orthogonal directions.
Le premier chariot inférieur comporte des roulettes aptes à autoriser son déploiement en translation le long du support par l'actionnement d'un vérin à course longitudinale jusqu'à la venue en engagement de l'extrémité postérieure en forme de coin contre le sol. Le deuxième chariot est superposé au premier chariot à la descente et à la remontée, et est en liaison avec un outil spécifique destiné à immobiliser ou à réceptionner les deux roues avant ou arrière du véhicule. The first lower carriage comprises wheels able to allow its deployment in translation along the support by actuating a longitudinal stroke cylinder until the engagement of the posterior wedge-shaped end against the ground. The second carriage is superimposed on the first carriage on the descent and the ascent, and is in connection with a specific tool for immobilizing or receiving the two front or rear wheels of the vehicle.
Tous les équipements spécifiques à la présente invention seront fixés directement sur le châssis de la chenillette motorisée. All equipment specific to the present invention will be directly attached to the chassis of the motorized track.
Il est ainsi possible de remplacer la dépanneuse légère 4/4 équipée d'un bras hydraulique par ce dispositif selon l'invention, et de rendre superflu le camion plateau équipé d'un plateau basculant, d'un bras et treuil hydraulique au profit d'un simple camion plateau, dont l'investissement est considérablement inférieur. It is thus possible to replace the light 4/4 towing device equipped with a hydraulic arm by this device according to the invention, and to make superfluous the flatbed truck equipped with a tilting tray, an arm and hydraulic winch for the benefit of a simple flatbed truck, whose investment is considerably lower.
Selon un mode de réalisation préférentiel, le premier cadre du mécanisme hydraulique à fourche étant relié au deuxième chariot par une liaison à pivot. Le premier cadre comporte deux tubes coulissants dans la direction longitudinale pour constituer des moyens d'appui extérieur aux deux pneus, et en étant conformés en coin pour mieux se glisser sous lesdits pneus. Le deuxième cadre comporte deux tubes destinés à coulisser dans la direction transversale au moyen de deux vérins de manière à emprisonner ou à libérer l'intérieur desdits pneus. According to a preferred embodiment, the first frame of the hydraulic fork mechanism is connected to the second carriage by a pivot connection. The first frame comprises two sliding tubes in the longitudinal direction to constitute external support means to the two tires, and being shaped wedge to better fit under said tires. The second frame comprises two tubes intended to slide in the transverse direction by means of two jacks so as to trap or release the inside of said tires.
Selon une caractéristique de l'invention, le deuxième chariot est équipé avantageusement d'un dispositif de freinage de sécurité automatique apte à bloquer ledit chariot tractant le véhicule lorsque le treuil est à l'arrêt, et à le libérer lorsque le câble du treuil est sollicité en traction. According to a characteristic of the invention, the second trolley is advantageously equipped with an automatic safety braking device able to block said trolley towing the vehicle when the winch is stopped, and to release it when the cable of the winch is stressed in traction.
Un avantage est une réduction du temps sur l'opération de dépannage, en particulier la phase de chargement du véhicule immobilisé, afin de réduire la gêne éventuelle de la circulation. Le premier chariot en position supérieure est libre, et charge les roues avant du véhicule, le second chariot est actionné par un vérin hydraulique, et se positionne sous les roues arrière, et un treuil tracte ensuite le chariot libre avec le véhicule sur le châssis principal. En situation courante, le chargement ne prend que quelques minutes avec un seul opérateur. La commande de la centrale hydraulique permet une première séquence au cours de laquelle l'ensemble du mécanisme sera en premier incliné et déployé, puis il faut emprisonner et simultanément soulever légèrement les roues avant du véhicule, puis selon que les roues arrière soient libres ou bloquées, de faire avancer la chenillette vers le véhicule et simultanément actionner le treuil, et le deuxième chariot supérieur va se déplacer en remontant sur le support inclinable vers l'avant. Puis, une fois l'avant du véhicule treuillé en butée, le premier chariot inférieur hydraulique viendra s'appuyer contre les roues arrière, et le véhicule sera basculé à l'horizontale. Cette combinaison de mouvement rend inutile la mise en place de chariots à roulettes sous les roues arrière puisque le véhicule sera chargé sans qu'il soit déplacé. Un autre avantage est que le dispositif de remorquage est fixé à demeure sur une chenillette très basse, afin qu'un véhicule chargé soit généralement accessible à la hauteur la plus basse des parkings souterrain. Si nécessaire, il est encore possible de tirer directement le véhicule avec la chenillette jusqu'à l'extérieur en le soulevant par les roues avant et le tractant sur les roues arrières. Dans le cas où celles-ci sont bloquées, il est possible de glisser un jeu de chariot à roulettes sous les roues arrière. En outre, la motorisation des chenilles offre l'avantage de tourner sur place, ce qui s'avère très utile dans les parkings, et pour réduire les couloirs de rangement des véhicules dans les fourrières par exemple. One advantage is a reduction of the time on the repair operation, in particular the loading phase of the immobilized vehicle, in order to reduce the possible annoyance of the traffic. The first carriage in the upper position is free, and load the front wheels of the vehicle, the second carriage is actuated by a hydraulic cylinder, and is positioned under the rear wheels, and a winch then tows the free carriage with the vehicle on the main frame . In current situation, loading takes only a few minutes with a single operator. The control of the hydraulic power unit allows a first sequence during which the entire mechanism will be first inclined and deployed, then it is necessary to trap and simultaneously lift slightly the front wheels of the vehicle, then according to whether the rear wheels are free or blocked , advance the track to the vehicle and simultaneously operate the winch, and the second upper carriage will move upward on the tilting support forward. Then, once the front of the vehicle winnably abut, the first hydraulic lower carriage will come to rest against the rear wheels, and the vehicle will be tilted horizontally. This combination of movements makes it unnecessary to install wheeled carriages under the rear wheels since the vehicle will be loaded without being moved. Another advantage is that the towing device is fixed permanently on a very low track, so that a loaded vehicle is generally accessible at the lowest height of the underground car parks. If necessary, it is still possible to pull the vehicle directly with the vehicle to the outside by lifting it by the front wheels and pulling it on the rear wheels. In the case where these are blocked, it is possible to slide a set of trolley with wheels under the rear wheels. In addition, the motorization of caterpillars has the advantage of turning on site, which is very useful in car parks, and to reduce vehicle storage corridors in pounds, for example.
Il est aussi possible de remorquer un véhicule de poids et de taille supérieure à un véhicule léger ou 4/4, par exemple un fourgon, sous réserve que celui-ci soit roulant. Pour ce faire le chariot porte roue avant sera en position déverrouillé pour permettre au véhicule remorqué de prendre des virages, les roues avant du véhicule seront emprisonnées et le chariot porte roue remonté jusqu'au bord du support et des chenilles, afin de laisser une liberté de mouvement au véhicule tracté, et roulant sur ses roues arrières. Il en résulte une grande mobilité de la chenillette permettant de dégager très rapidement le véhicule immobilisé, y compris dans un espace réduit. It is also possible to tow a vehicle of weight and size larger than a light vehicle or 4/4, such as a van, provided that it is rolling. To do this, the front wheel trolley will be in the unlocked position to allow the towed vehicle to take turns, the front wheels of the vehicle will be trapped and the trolley wheel up to the edge of the support and tracks, to leave a freedom of movement to the towed vehicle, and rolling on its rear wheels. This results in a high mobility of the track to quickly clear the immobilized vehicle, including in a small space.
Un autre avantage est de permettre à l'appareil de remorquage d'accéder directement au chargement et déchargement de véhicules accidentés sur un camion porte voiture, ce que les dispositifs connus ne permettent pas. Dans ce cas, le chargement nécessite un chariot élévateur par exemple, et le chargement/déchargement peut s'avérer très fastidieux. A cet effet, le châssis devra pouvoir basculer vers le haut pour faciliter le chargement du véhicule sur les ridelles inclinées des camions porte voiture. On peut ainsi imaginer qu'en cas de carambolage par exemple, la voie puisse être rapidement dégagée avec la seule chenillette de dépannage objet de l'invention, et un camion porte voiture, au lieu de mobiliser plusieurs dépanneuses. L'autonomie de déplacement de la chenillette, son extrême motricité, sa faculté de pivoter sur place, et la présence du mécanisme de remorquage qui lui est associé, permet une nouvelle organisation de dépannage, par exemple le chargement d'un camion plateau porteur pour 4 à 6 voitures, le camion restant parqué à proximité du lieu de remorquage, et la chenillette faisant de courtes navettes pour charger le plateau. Cette formule prendrait tout son intérêt pour évacuer des parkings, des véhicules à mettre en fourrière, dégager au plus vite un accident impliquant plusieurs véhicules, etc.... Another advantage is to allow the towing apparatus to have direct access to the loading and unloading of damaged vehicles on a truck carrier, which the known devices do not allow. In this case, the loading requires a forklift for example, and loading / unloading can be very tedious. For this purpose, the chassis must be able to tilt upward to facilitate the loading of the vehicle on the inclined sideboards of the trucks car carrier. It can thus be imagined that, in the case of a pileup, for example, the track can be rapidly cleared with the only recovery vehicle object of the invention, and a truck carrier, instead of mobilizing several tow trucks. The autonomy of movement of the track, its extreme traction, its ability to rotate on the spot, and the presence of the towing mechanism associated with it, allows a new organization of troubleshooting, for example the loading of a flatbed truck for 4 to 6 cars, the truck remaining parked near the towing site, and the tank making short shuttle to load the tray. This formula would take all its interest to evacuate car parks, vehicles to be impounded, to release as quickly as possible an accident involving several vehicles, etc.
Selon une variante de réalisation, l'outil amarré au deuxième chariot est constitué par une paire de plateaux latéraux en forme de coins, servant de moyens d'appui à l'avant ou à l'arrière d'un véhicule accidenté. Le véhicule sera alors transféré, son avant sur ce plateau, et son arrière sur le plateau destiné à recevoir les roues arrières, ce transfert pouvant être réalisé par le treuil disponible en tête de chenillette, ce qui dispense d'avoir recours à des engins de levage annexe. Le véhicule pourra alors être tracté pour dégager les lieux, puis sanglé pour sécuriser son transport. According to an alternative embodiment, the tool moored to the second carriage is constituted by a pair of wedge-shaped side plates, serving as support means to the front or rear of a damaged vehicle. The vehicle will then be transferred, its front on this plate, and its rear on the plate intended to receive the rear wheels, this transfer being able to be realized by the winch available at the head of the snowcat, which exempts to resort to vehicles of auxiliary lifting. The vehicle can then be towed to clear the scene, then strapped to secure transport.
Selon une autre variante, le deuxième chariot peut être motorisé, et comporte à cet effet un moteur hydraulique fixé en tête du support inclinable, un pignon à chaîne de renvoi fixé sur un support décalé solidaire du support, et deux pignons à chaîne solidaire du premier chariot inférieur. According to another variant, the second carriage can be motorized, and comprises for this purpose a hydraulic motor fixed at the head of the tilting support, a sprocket with a return chain fixed on an offset support secured to the support, and two chain sprockets integral with the first lower carriage.
La chenillette peut être chargée dans un fourgon standard de moins de 3,5T, longueur de chargement inférieure à 3 ,5M et largeur de passage entre roues inférieur à 2m. L'encombrement compact du mécanisme en position replié est de 2,5M en longueur, et 3,4M avec la chenillette, de 1,9M en largeur, et de 45cm pour la hauteur de chargement du véhicule, et moins de 1M à vide avec la chenillette. L'extrémité en coin des butées des roues avant et arrières sont configurées pour que celles-ci viennent en appui contre les roues, et une fois le véhicule relevé , l'appui des roues étant suffisant sur ces coins pour que le véhicule soit en position stable, ce qui offre l'avantage de dégager immédiatement les lieux. Lorsqu'on se trouve en situation plus confortable, il sera possible de sangler deux roues par sécurité . The trailer can be loaded in a standard van of less than 3.5T, loading length less than 3.5M and width of passage between wheels less than 2m. The compact size of the mechanism in the folded position is 2.5M in length, and 3.4M with the track, 1.9M in width, and 45cm for the loading height of the vehicle, and less than 1M empty with the caterpillar. The corner end of the stops of the front and rear wheels are configured so that they bear against the wheels, and once the vehicle is raised, the support of the wheels being sufficient on these corners so that the vehicle is in position stable, which offers the advantage of immediately clearing the premises. When in a more comfortable situation, it will be possible to strap two wheels for safety.
Un autre avantage est d'utiliser l'extrémité en saillie du chariot arrière comme moyen de manutention, associé à la mobilité des chenillettes, pour dégager un véhicule accidenté en le soulevant et le déplaçant dans tous les sens. On peut encore utiliser avantageusement les appuis des deux chariots, pour poser et retirer un container sur roulettes, puisque l'écartement entre ces appuis est réglable. Le mécanisme de dépannage, remplace alors économiquement un chariot à fourche élévateur, ou un camion plateau équipé d'une potence hydraulique. Another advantage is to use the projecting end of the rear carriage as a means of handling, associated with the mobility of the carriages, to clear a vehicle accident by lifting and moving in all directions. It is still possible to use advantageously the supports of the two carriages, for laying and removing a container on wheels, since the spacing between these supports is adjustable. The recovery mechanism then economically replaces a forklift, or a flatbed truck equipped with a hydraulic stem.
Le mécanisme objet de la présente invention propose donc de résoudre avec ce dispositif l'ensemble des opérations de dépannage et de remorquage et accessoirement de manutention de containers nécessitant jusqu'à ce jour plusieurs véhicules équipés de leurs appareils. The mechanism object of the present invention therefore proposes to solve with this device all the troubleshooting and towing operations and incidentally container handling requiring up to this day several vehicles equipped with their devices.

Description détaillée de l'invention Detailed description of the invention
Sur les figures 1 à 3, l'appareil de remorquage est constitué d'un mécanisme installé sur une chenillette 1 , laquelle est motorisée par une centrale hydraulique 3 asservie à un moteur thermique, et pilotée par un boîtier de commande filaire ou de préférence radiocommandé, non représenté. In Figures 1 to 3, the towing device consists of a mechanism installed on a track 1, which is powered by a hydraulic unit 3 controlled by a heat engine, and controlled by a wired control unit or preferably radio controlled , not shown.
Cette chenillette 1 étant un outil de manutention connu proposé par divers fabricants spécialisés, ne sera pas directement concernée par l'invention, mais le mécanisme objet de l'invention tire avantageusement partie de ses capacités. This track 1 being a known handling tool proposed by various specialized manufacturers, will not be directly concerned by the invention, but the mechanism object of the invention advantageously takes advantage of its capabilities.
La chenillette 1 dispose de deux chenilles 1a, 1b, chacune motorisée par un moteur hydraulique 4a, 4b, et d'un châssis métallique 2 sur lequel est fixé l'ensemble du mécanisme de remorquage objet de l'invention. The track 1 has two tracks 1a, 1b, each powered by a hydraulic motor 4a, 4b, and a metal frame 2 on which is fixed the entire towing mechanism object of the invention.
L'appareil de remorquage est constitué d'un support 5 inclinable conformé selon une poutre roulante sur l'extérieur et l'intérieur de ses sections 5a, 5b, reliées par des traverses 6a, 6b. L'inclinaison du support 5 dans la direction de la flèche H (figure 2) est obtenue au moyen de deux vérins hydrauliques 30a, 30b eux-mêmes fixés au châssis 2 de la chenillette 1. The towing apparatus consists of a tiltable support 5 shaped according to a rolling beam on the outside and inside of its sections 5a, 5b, connected by cross members 6a, 6b. The inclination of the support 5 in the direction of the arrow H (Figure 2) is obtained by means of two hydraulic cylinders 30a, 30b themselves attached to the frame 2 of the track 1.
Un premier chariot 7 peut se déplacer en translation le long du support 5 inclinable grâce à des roulettes 8a, 8b, 8c, et à l'actionnement d'un vérin hydraulique 9 à longue course, lequel est fixé d'un côté à la traverse 6a, et de l'autre à l'extrémité avant du premier chariot 7. L'extrémité de ce chariot 7 est conformée en coin afin de se glisser au plus près du pneu du véhicule.A first carriage 7 can move in translation along the tilting support 5 by means of rollers 8a, 8b, 8c, and the actuation of a long-stroke hydraulic cylinder 9, which is fixed on one side to the transom 6a, and the other at the front end of the first carriage 7. The end of the carriage 7 is wedge shaped to slide closer to the vehicle tire.
La course du premier chariot 7 est comprise à titre d'exemple entre 1 ,5 m et 2 m. Après un mouvement d'inclinaison du support 5, et du déploiement total du premier chariot 7, celui ci vient accoster le sol, en appui sur sa roulette avant 23. The stroke of the first carriage 7 is included as an example between 1.5 m and 2 m. After a tilting movement of the support 5, and the total deployment of the first carriage 7, it comes dock the ground, resting on its front wheel 23.
Un deuxième chariot 8 peut se déplacer à l'extérieur du support inclinable 5, grâce à ses roulettes 9a, 9b, mais également à l'intérieur du premier chariot 7 grâce à ses roulettes intérieures 10a, 10b. Ce chariot 8 est libre, mais peut être tiré par un treuil 11 et son câble 12 pour remonter après chargement depuis la position de recul (figure 2) jusqu'à sa position avant (figure 1). Le treuil 1 est fixé préférentiellement à l'avant du support 5 inclinable, et au- dessus des vérins 30a, 30b hydrauliques. Suivant la figure 4, le deuxième chariot 8 est attelé à un mécanisme à fourche MF destiné à emprisonner les roue avant ou arrière du véhicule, suivant que le véhicule est remorqué à l'endroit ou à l'envers. Ce mécanisme à fourche MF est constitué d'un premier cadre tubulaire 13 relié au deuxième chariot 8 par un pivot 16, et roulant au sol grâce aux roulettes 14a, 14b, 15a, 15b. Le premier cadre tubulaire 13 est relié par coulissement longitudinal suivant la direction de la flèche A à un second cadre tubulaire 17a, 17b, associé à un tube diagonale 17c. Le premier cadre 13 est équipé de deux tubes 19a, 19b diagonaux coulissants horizontalement, qui serviront de moyens d'appui extérieur aux deux pneus, et conformés en coin 34a, 34b à leur extrémité afin de se glisser au plus près du pneu. Le second cadre 17 est équipé également de deux tubes 20a, 20b en diagonale coulissant horizontalement dans la direction de la flèche B, et pouvant s'escamoter complètement à l'intérieur du tube 17c, et sortir grâce à l'action de deux vérins hydrauliques 21 et 22 travaillant simultanément et en opposition. A second carriage 8 can move outside the tilting support 5, with its rollers 9a, 9b, but also inside the first carriage 7 with its inner rollers 10a, 10b. This carriage 8 is free, but can be pulled by a winch 11 and its cable 12 to go back after loading from the recoil position (Figure 2) to its forward position (Figure 1). The winch 1 is preferably fixed to the front of the tilting support 5, and above the hydraulic cylinders 30a, 30b. According to Figure 4, the second carriage 8 is coupled to an MF fork mechanism for trapping the front or rear wheel of the vehicle, depending on whether the vehicle is towed to the place or upside down. This MF fork mechanism consists of a first tubular frame 13 connected to the second carriage 8 by a pivot 16, and rolling on the ground thanks to the rollers 14a, 14b, 15a, 15b. The first tubular frame 13 is connected by longitudinal sliding in the direction of arrow A to a second tubular frame 17a, 17b, associated with a diagonal tube 17c. The first frame 13 is equipped with two tubes 19a, 19b diagonal sliding horizontally, which will serve as external support means to the two tires, and shaped wedge 34a, 34b at their ends to slide closer to the tire. The second frame 17 is also equipped with two tubes 20a, 20b diagonally sliding horizontally in the direction of the arrow B, and can retract completely inside the tube 17c, and out through the action of two hydraulic cylinders 21 and 22 working simultaneously and in opposition.
Les tubes 20a, 20b, viendront emprisonner le côté intérieur du pneu, puis un vérin hydraulique 18 va rapprocher les deux cadres 13 et 17 en contact avec les deux faces intérieure et extérieure du pneu, jusqu'à pouvoir décoller légèrement le véhicule du sol, si nécessaire, par exemple si la roue est crevée. The tubes 20a, 20b, will trap the inner side of the tire, then a hydraulic cylinder 18 will bring the two frames 13 and 17 in contact with the two inner and outer faces of the tire, until the vehicle is slightly off the ground, if necessary, for example if the wheel is punctured.
Dans la variante simplifiée illustrée à la figure 13, le mécanisme à fourche MF de la figure 3, est remplacé par deux plateaux 36a, 36b latéraux en forme de coins dimensionnés pour que la roue prenne appui, après franchissement de la pente du coin. Les roues pourront ensuite venir s'appuyer en butée contre deux cales amovibles 37a, 37b. En référence aux figures 5 et 6, le deuxième chariot 8 comporte en outre un dispositif de freinage DF constitué d'un arbre de commande 24, guidé au moyen de quatre paliers 25a, 25b, 25c, 25d, et solidaire en rotation de deux paliers à friction 26a, 26b. Au repos, ces paliers sont appliqués contre le support 5, et/ou le premier chariot 7 positionné en alignement, le freinage étant obtenu grâce à la force exercée par des ressorts à gaz 27a, 27b, reliés à des leviers de transmission 28a, 28b, solidaires de l'arbre de commande 24. L'arbre de commande 24 est coudé dans sa partie centrale pour recevoir le câble 12 du treuil 11 hydraulique. Lorsque le câble 12 est dans un état de traction sous l'action du treuil 1 , celui-ci fait pivoter l'arbre de commande 24 sur ses paliers, ce qui a pour effet de relever les patins à friction 26a, 26b, et donc de libérer le deuxième chariot 8. A l'inverse, l'arrêt du treuil 11 suivi du desserrage du câble 12, entraine le freinage du deuxième chariot 8 et son immobilisation immédiate en position. Cette action de freinage empêche le véhicule en cours de remorquage, de repartir en arrière pendant son chargement. Une came 29 peut actionnée manuellement les leviers de transmission 28a, 28b pour débloquer le frein lorsqu'il n'est pas lié au treuil 11 , par exemple à la descente du deuxième chariot 8 à vide. In the simplified variant illustrated in Figure 13, the MF fork mechanism of Figure 3, is replaced by two trays 36a, 36b lateral shaped wedges dimensioned for the wheel to bear after crossing the slope of the corner. The wheels can then abut abut against two removable blocks 37a, 37b. With reference to FIGS. 5 and 6, the second carriage 8 further comprises a braking device DF consisting of a control shaft 24, guided by means of four bearings 25a, 25b, 25c, 25d, and integral in rotation with two bearings. friction 26a, 26b. At rest, these bearings are applied against the support 5, and / or the first carriage 7 positioned in alignment, the braking being obtained thanks to the force exerted by gas springs 27a, 27b, connected to transmission levers 28a, 28b , integral with the control shaft 24. The control shaft 24 is bent in its central portion to receive the cable 12 of the hydraulic winch 11. When the cable 12 is in a state of traction under the action of the winch 1, it rotates the control shaft 24 on its bearings, which has the effect of raising the friction pads 26a, 26b, and therefore to release the second carriage 8. Conversely, stopping the winch 11 followed loosening of the cable 12, causes the braking of the second carriage 8 and its immediate immobilization in position. This braking action prevents the vehicle being towed from going back during loading. A cam 29 can manually actuate the transmission levers 28a, 28b to release the brake when it is not connected to the winch 11, for example to the descent of the second carriage 8 to empty.
Selon une autre variante illustrée à la figure 14, le deuxième chariot 8 peut optionnellement être motorisé. A la place du treuil 11 et du câble 12 des figures 1 et 2, le dispositif comporte dans ce cas un moteur hydraulique 38 fixé en tète du châssis inclinable 5, un pignon à chaîne de renvoi 42 fixé sur un support décalé 43 solidaire du châssis 5, et deux pignons à chaîne 40, 41 fixés sur le premier chariot 7 inférieur. According to another variant illustrated in Figure 14, the second carriage 8 may optionally be motorized. Instead of the winch 11 and the cable 12 of FIGS. 1 and 2, the device comprises in this case a hydraulic motor 38 fixed at the head of the tilting frame 5, a sprocket with a return chain 42 fixed on an offset support 43 secured to the chassis 5, and two chain sprockets 40, 41 fixed to the first lower carriage 7.
La chaîne de motorisation 39 est reliée au deuxième chariot 8 supérieur par une attache 44, et se trouve toujours dans un état tendu pendant le déplacement du premier chariot 7, lequel peut se mouvoir indépendamment de la chaîne 39. Lorsque le premier chariot 7 inférieur est dans la position déployée, le deuxième chariot 8 supérieur peut être piloté à son tour grâce au moteur hydraulique 38 dans la direction des flèches H, J, les autres systèmes de guidage précédemment décrits restant identiques et non représentés sur la figure 14. Un tel dispositif rend inutile le dispositif de freinage DF du deuxième chariot 8 décrit précédemment aux figures 5 et 6, puisque le moteur hydraulique 38 est naturellement bloqué à l'arrêt. Ce mécanisme à en outre l'avantage de simplifier la manœuvre du deuxième chariot 8, puisque le mécanisme à treuil 11 des figures 1-3 implique que son pilotage doit être combiné avec la manœuvre du premier chariot 7, ceci afin de maintenir toujours le câble 12 en tension. The drive chain 39 is connected to the second upper carriage 8 by a fastener 44, and is always in a tense state during the movement of the first carriage 7, which can move independently of the chain 39. When the first lower carriage 7 is in the deployed position, the second upper carriage 8 can be driven in turn thanks to the hydraulic motor 38 in the direction of the arrows H, J, the other guidance systems described above remaining identical and not shown in Figure 14. Such a device makes unnecessary the braking device DF of the second carriage 8 previously described in Figures 5 and 6, since the hydraulic motor 38 is naturally blocked when stopped. This mechanism also has the advantage of simplifying the operation of the second carriage 8, since the winch mechanism 11 of FIGS. 1-3 implies that its piloting must be combined with the operation of the first carriage 7, this in order to always maintain the cable 12 in tension.
Description d'une séquence de dépannage et remorquage d'un véhicule, suivant les figures 7, 8 et 9. Description of a sequence of troubleshooting and towing a vehicle, according to Figures 7, 8 and 9.
Sur la figure 7, l'appareil de remorquage est déployé totalement, et tout le mécanisme est incliné par l'action des vérins 30a, 30b de relevage du support 5. Simultanément, le vérin 9 à grande course est actionné, et pousse le premier chariot intérieur 7 jusqu'à l'accostage au sol de la roulette 23. Toujours simultanément, le dispositif de freinage DF du treuil 1 peut être débloqué, ce qui a pour effet de libérer le deuxième chariot 8 supérieur et extérieur, qui peut rouler librement par gravité à la fois dans le support 5 et le premier chariot 7. Après avoir franchi l'extrémité du support 5, il peut rouler encore dans le premier chariot 7 jusqu'à l'accostage au sol des roulettes 14, 5, 31 du cadre avant. Le deuxième chariot 8 ne peut pas sortir du premier chariot 7, car ses roulettes 10a, b, viennent en butée dans le profil en coin de l'avant du chariot 7. In FIG. 7, the towing apparatus is deployed completely, and the entire mechanism is inclined by the action of the lifting jacks 30a, 30b of the support 5. Simultaneously, the jack 9 with a large stroke is actuated, and pushes the first internal carriage 7 until the landing of the wheel 23. Simultaneously, the braking device DF of the winch 1 can be unlocked, which has the effect of releasing the second carriage 8 upper and outer, which can roll freely by gravity in both the support 5 and the first carriage 7. After having crossed the end of the support 5, it can roll again in the first carriage 7 until the landing on the ground wheels 14, 5, 31 of the front frame. The second carriage 8 can not leave the first carriage 7 because its rollers 10a, b abut in the corner profile of the front of the carriage 7.
Ainsi que décrit précédemment suivant la figure 4, le cadre porte roue avance contre l'extérieur du pneu jusqu'aux cales 19a, 19b. Le coin 34a, 34b formé sur l'avant des cales 19a, 19b se glisse jusqu'au contact du pneu. Le vérin 18 maintient écartés les deux cadres 13 et 17, et les cales de roues 20a, 20b sont rétractées pour libérer le passage. Puis les vérins 21 et 22 sortent les cales de roues 20a, 20b, et le vérin 18 comprime les cales contre les pneus jusqu'à soulever légèrement le véhicule si nécessaire. Le câble 12 du treuil 11 sera déroulé et accroché au deuxième chariot 8, et le treuil 11 est ensuite embrayé. As described above according to Figure 4, the wheel frame advances against the outside of the tire to the wedges 19a, 19b. The wedge 34a, 34b formed on the front of the wedges 19a, 19b slides to the contact of the tire. The cylinder 18 holds apart the two frames 13 and 17, and the wheel chocks 20a, 20b are retracted to release the passage. Then the cylinders 21 and 22 out the wheel chocks 20a, 20b, and the cylinder 18 compresses the wedges against the tires until slightly lift the vehicle if necessary. The cable 12 of the winch 11 will be unrolled and hooked to the second carriage 8, and the winch 11 is then engaged.
Cette première opération ne prend que quelques minutes. La seconde étape, représentée à la figure 8, se déroule suivant deux cas : 1er cas : le véhicule est immobilisé, portes fermées avec les roues bloquées par la transmission et/ou le frein à main. Le véhicule ne peut donc se déplacer, et pourrait être endommagé s'il était tracté dans ces conditions. Dans ce cas, c'est la chenillette 1 qui avance dans la direction de la flèche C, pendant que le premier chariot 7 est maintenu verrouillé en position déployée grâce à son vérin 9 de translation, et roule sur le sol sur sa roulette 23 en se glissant sous le deuxième chariot 8. Ce dernier monte simultanément sur le premier chariot 7 grâce à ses roulettes 10a, 10b, qui forment pivot et permettent donc au mécanisme à fourche MF porte roue qui est arrimée au deuxième chariot 8 de rouler sur le dessus du premier chariot 7 grâce aux roulettes 14a, 14b, puis 15a, 15b puis 31a, 31b. Ainsi, ce n'est pas le véhicule qui bouge ou est tracté, mais le chariot 7 qui s'avance sous le véhicule, poussé par les chenilles 1a, 1b. Le véhicule ne peut pas reculer, grâce au dispositif de freinage DF qui le bloque à l'arrêt, et seule la traction du câble 12 libère ce frein. Simultanément, le deuxième chariot 8 est rétracté vers l'avant, afin qu'il ne prenne pas encore en charge les roues arrières. Lorsque le deuxième chariot 8 est à proximité immédiate du treuil 11 , le premier chariot 7 peut alors avancer jusqu'à ce que son bec avant soit en contact avec l'intérieur des pneus arrière. This first operation only takes a few minutes. The second step, shown in Figure 8, takes place in two cases: 1st case: the vehicle is immobilized, doors closed with the wheels locked by the transmission and / or the handbrake. The vehicle can not move, and could be damaged if towed under these conditions. In this case, it is the track 1 which advances in the direction of the arrow C, while the first carriage 7 is kept locked in the deployed position by means of its translation cylinder 9, and rolls on the ground on its wheel 23. slipping under the second carriage 8. The latter simultaneously rides on the first carriage 7 with its wheels 10a, 10b, which form a pivot and thus allow the MF forklift wheel mechanism which is secured to the second carriage 8 to roll on top of the first carriage 7 by means of the rollers 14a, 14b, then 15a, 15b and 31a, 31b. Thus, it is not the vehicle that moves or is towed, but the carriage 7 which protrudes under the vehicle, pushed by the tracks 1a, 1b. The vehicle can not move back, thanks to the braking device DF which blocks it when stopped, and only the traction of the cable 12 releases this brake. Simultaneously, the second carriage 8 is retracted forward, so that it does not yet support the rear wheels. When the second carriage 8 is in the immediate vicinity of the winch 11, the first carriage 7 can then advance until its front nose is in contact with the inside of the rear tires.
En fin de cette étape, le véhicule est en appui avec ses roues arrière sur le premier chariot incliné 7, et les roues avant bloquées sur le cadre du deuxième chariot 8. 2eme cas : le véhicule est roulant. Cette situation est beaucoup plus simple, puisque le véhicule peut être directement tracté par le treuil 11. At the end of this step, the vehicle is supported with its rear wheels on the first inclined carriage 7, and the front wheels locked on the frame of the second carriage 8. 2nd case: the vehicle is rolling. This situation is much simpler, since the vehicle can be directly pulled by the winch 11.
Dernière étape de l'arrimage : Last step of the stowage:
En fin de relevage illustré sur la figure 9, le vérin 30a, 30b d'inclinaison sera activer pour redresser le véhicule sensiblement à l'horizontale, et pourra être tracté par la chenillette 1 , ou chargé avec la chenillette sur un camion plateau (non représenté). At the end of lifting illustrated in Figure 9, the cylinder 30a, 30b of inclination will be activated to straighten the vehicle substantially horizontally, and may be towed by the track 1, or loaded with the truck on a flatbed truck (no represent).
Le redressement du véhicule aura pour effet de favoriser le calage des roues contre les coins 34a, 34b et l'extrémité du premier chariot 7, puisque le poids du véhicule bascule contre ceux-ci . The recovery of the vehicle will have the effect of promoting the wedging of the wheels against the corners 34a, 34b and the end of the first carriage 7, since the weight of the vehicle tilts against them.
Cette configuration va assurer à elle seule un bon appui et une stabilité suffisante du véhicule , autorisant la chenillette 1 ainsi chargée à se déplacer sur de faibles distances.  This configuration alone will ensure good support and sufficient stability of the vehicle, allowing the tracker 1 thus loaded to travel at short distances.
Pour le remorquage longue distances, par sécurité, les roues pourront être sanglées sur le cadre du deuxième chariot 8, grâce à des sangles à cliquet et des arrêts de sangle (non représentés). Suivant la figure 10, dans le cas où le véhicule devra être chargé sur un camion porte auto, l'accès aux rampes inclinées propres à ce type de camion sera facilité en inclinant le véhicule au dessus de l'horizontale, suivant la flèche D, grâce aux vérins 30a, 30b, qui en position fermée sollicitent l'avant du support 5 dans la direction de la fléché E. Le support 5 vient alors en appui sur la butée à roulement 31a, 31b et grâce à la configuration des biellettes arrière 32, celles-ci se lèvent de la butée 33a, 33b et provoquent le relevage du support 5 .  For long haul towing, for safety, the wheels can be strapped to the frame of the second carriage 8, thanks to ratchet straps and strap stops (not shown). According to Figure 10, in the case where the vehicle will be loaded on a truck carrier, access to inclined ramps specific to this type of truck will be facilitated by tilting the vehicle above the horizontal, along the arrow D, thanks to the jacks 30a, 30b, which in the closed position urge the front of the support 5 in the direction of the arrow E. The support 5 then bears against the rolling stop 31a, 31b and thanks to the configuration of the rear links 32 , they rise from the stop 33a, 33b and cause the lifting of the support 5.
Suivant les figures 4 et 11 , dans le cas ou le véhicule est tractable, il conviendra préalablement d'enlever la goupille 35 pour permettre la rotation des deux parties du deuxième chariot 8 suivant l'axe 16 vertical et les directions F, G. Puis, les roues avant du véhicule seront chargées comme décrit précédemment dans la première étape de la figure 7, et le deuxième chariot 8 supérieur sera remonté avec le treuil 11 jusqu'à l'extrémité du support 5 basculant , et le premier chariot 7 inférieur sera remonté hydrauliquement jusqu'en butée. According to FIGS. 4 and 11, in the case where the vehicle is towable, it will first be necessary to remove the pin 35 to allow rotation of the two parts of the second carriage 8 along the vertical axis 16 and the directions F, G. Then , the front wheels of the vehicle will be loaded as previously described in the first step of Figure 7, and the second upper carriage 8 will be raised with the winch 11 to the end of the tilting support 5, and the first lower carriage 7 will be reassembled hydraulically to the stop.
Dans cette situation, le véhicule peut être tracté, le support 5 restant relevé, ou descendu dans le sens de la flèche H. In this situation, the vehicle can be towed, the support 5 remaining raised, or lowered in the direction of the arrow H.
Dans le cas d'un véhicule accidenté non roulant, celui-ci pourra être déplacé grâce à la configuration de l'extrémité du premier chariot 7 suivant la figure 12, car les cales en coin 35a, 35b s'appuyant contre les roues peuvent également s'introduire sous le châssis du véhicule, puis le premier chariot 7 peut être légèrement relevé grâce aux vérins 30a, 30b, et le véhicule ainsi partiellement soulevé peut être manœuvré par la chenillette 1 grâce à l'extrême motricité et mobilité des chenilles 1a,b. In the case of a non-rolling accident vehicle, it may be moved by virtue of the configuration of the end of the first carriage 7 according to FIG. 12, since the wedge wedges 35a, 35b resting against the wheels may also be displaced. to be introduced under the chassis of the vehicle, then the first carriage 7 can be slightly raised with the jacks 30a, 30b, and the partially raised vehicle can be maneuvered by the track 1 thanks to the extreme traction and mobility of the tracks 1a, b.
L'appareil de remorquage selon l'invention permet aussi de charger latéralement un véhicule, en particulier lorsque l'accès par l'avant ou l'arrière du véhicule est impossible. The towing apparatus according to the invention also makes it possible to load a vehicle laterally, in particular when access from the front or the rear of the vehicle is impossible.
