Description

Installation de gonflage et de surveillance de pneumatiques montés sur un véhicule.Inflation and monitoring installation for tires mounted on a vehicle.
La présente invention concerne une installation de gonflage et de surveillance de pneumatiques montés sur un véhicule automobile .The present invention relates to an installation for inflating and monitoring tires mounted on a motor vehicle.
On connaît, par exemple par DE-A-2 746 757, des systèmes de gonflage de pneumatiques comprenant une pompe montée sur la jante de la roue portant le pneumatique et actionnée par la bande de roulement du pneumatique dégonflé. Un tel système est fragile, du fait de son montage sur la jante et de son actionnement purement mécanique par le pneumatique dégonflé.DE-A-2 746 757 discloses, for example, tire inflation systems comprising a pump mounted on the rim of the wheel carrying the tire and actuated by the tread of the deflated tire. Such a system is fragile, due to its mounting on the rim and its purely mechanical actuation by the deflated tire.
On a également proposé (voir FR-A-2 318 747) de diviser l'intérieur du pneumatique par une paroi et de déposer sur la jante de roue un moyen à valve assurant l'entrée d'air dans le pneumatique en cas de dégonflement. Cette solution nécessite un pneumatique spécial comportant une paroi interne étanche, ce qui est compliqué, onéreux et peu fiable.It has also been proposed (see FR-A-2 318 747) to divide the interior of the tire by a wall and to deposit on the wheel rim a valve means ensuring the entry of air into the tire in the event of deflation . This solution requires a special tire with a sealed internal wall, which is complicated, expensive and unreliable.
La présente invention vise en conséquence à pallier les inconvénients des systèmes connus grâce à une installation fiable, montée à demeure dans le véhicule et non susceptible d' usure .The present invention therefore aims to overcome the drawbacks of known systems thanks to a reliable installation, permanently mounted in the vehicle and not susceptible to wear.
A cet effet, l'invention a pour objet une installation de gonflage et/ou de surveillance des pneumatiques montés sur les jantes des roues d'un véhicule, caractérisée en ce qu'elle comprend un compresseur dont l'entrée est reliée à une prise d'air extérieur, par exemple le filtre à air, et dont la sortie est reliée à un réservoir d'air comprimé, ledit réservoir alimentant une vanne distributrice munie de deux sorties fermées en position de fermeture de la vanne, ladite vanne distributrice étant commandée à distance, chacune des sorties de ladite vanne alimentant respectivement une tubulure avant desservant au moins une roue avant et une tubulure arrière desservant au moins une roue arrière, chaque tubulure avant et arrière, étant raccordée à un conduit axial de l'axe de la roue correspondante, ce conduit axial étant raccordé à l'entrée d'un distributeur, une sortie dudit distributeur étant reliée à une valve de gonflage de pneumatique et l'autre sortie à une valve de prise de la pression dans le pneumatique qui commande l'alimentation de la valve de gonflage.To this end, the subject of the invention is an installation for inflating and / or monitoring tires mounted on the rims of the wheels of a vehicle, characterized in that it comprises a compressor whose input is connected to a socket of outdoor air, for example the air filter, and the outlet of which is connected to a compressed air tank, said tank supplying a dispensing valve provided with two closed outlets in the valve closed position, said dispensing valve being remotely controlled, each of the outputs of said valve supplying respectively a front pipe serving at least one front wheel and a rear pipe serving at least one rear wheel, each front and rear pipe being connected to an axial duct of the axis of the corresponding wheel, this axial duct being connected to the inlet of a distributor, one outlet of said distributor being connected to a tire inflation valve and the other outlet to a pressure taking valve in the tire which controls the supply of the inflation valve.
Le dispositif selon l'invention permet donc, avec des moyens simples et fiables, de regonfler les pneumatiques et de les maintenir à la pression requise, en roulant ou à l'arrêt.The device according to the invention therefore makes it possible, with simple and reliable means, to reinflate the tires and to maintain them at the required pressure, while driving or at a standstill.
L' invention sera bien comprise à la lecture de la description suivante d'un exemple de réalisation, en référence au dessin annexé dans lequel :The invention will be clearly understood on reading the following description of an exemplary embodiment, with reference to the appended drawing in which:

la figure 5 est une vue éclatée d'un distributeur etFIG. 5 is an exploded view of a dispenser and
la figure 6 est une vue en plan de l'équipage fixe du distributeur de la figure 5. L'installation selon l'invention est décrite en référence à un véhicule à quatre roues comprenant deux roues avant motrices directrices à cardan et deux roues arrières non motrices ni directrices .FIG. 6 is a plan view of the fixed equipment of the dispenser of FIG. 5. The installation according to the invention is described with reference to a four-wheeled vehicle comprising two front drive wheels with cardan joint and two rear wheels, neither drive nor guide.
Elle s'applique bien entendu à tous véhicules à au moins deux roues, que ces véhicules soient automobiles ou tractés.It obviously applies to all vehicles with at least two wheels, whether these vehicles are motorized or towed.
En référence à la figure 1, l'installation comprend, dans l'exemple représenté, une prise d'air, constitué par exemple par le filtre à air 1 du véhicule, relié, par une tubulure 2, à l'entrée d'un compresseur 3 dont la sortie est reliée, par une tubulure 4, à un réservoir d'air comprimé 5 ou bâche munie d'une soupape de surpression 17. La sortie du réservoir d'air comprimé 5 est reliée, par une tubulure 6, à une vanne distributrice 7 comprenant un clapet coulissant 8, commandé par une télécommande 19 et muni de joints 18. La vanne 7 comporte une sortie arrière 9 et une sortie avant 10. La sortie avant 10 est reliée à une tubulure 11, divergeant en une tubulure avant de droite 12 et une tubulure avant de gauche 13. De la même manière, la sortie 9 de la vanne 7 débouche dans une tubulure arrière 14 divergeant en une tubulure arrière de gauche 15 et une tubulure arrière de droite 16.Referring to Figure 1, the installation comprises, in the example shown, an air intake, constituted for example by the air filter 1 of the vehicle, connected, by a pipe 2, to the inlet of a compressor 3, the outlet of which is connected, by a pipe 4, to a compressed air tank 5 or tank provided with a pressure relief valve 17. The outlet of the compressed air tank 5 is connected, by a pipe 6, to a dispensing valve 7 comprising a sliding valve 8, controlled by a remote control 19 and provided with seals 18. The valve 7 has a rear outlet 9 and a front outlet 10. The front outlet 10 is connected to a pipe 11, diverging into a pipe front right 12 and a front left pipe 13. In the same way, the outlet 9 of the valve 7 opens into a rear pipe 14 diverging into a rear left pipe 15 and a rear right pipe 16.
Le clapet coulissant 8 occupe normalement une position de fermeture dans laquelle les sorties 9 et 10 sont fermées et la soupape de surpression 17 du réservoir 5 est ouverte. Sous l'action de la télécommande 19, le clapet 8 descend (sur la figure 1) et libère les sorties 9 et 10, la soupape de surpression 17 n'étant plus ouverte.The sliding valve 8 normally occupies a closed position in which the outlets 9 and 10 are closed and the pressure relief valve 17 of the reservoir 5 is open. Under the action of the remote control 19, the valve 8 descends (in FIG. 1) and releases the outputs 9 and 10, the pressure relief valve 17 no longer being open.
Les tubulures 15 et 16 sont respectivement reliées à un conduit axial 30 de l'axe 31 de la roue arrière non motrice respectiveTubing 15 and 16 are respectively connected to an axial duct 30 of the axis 31 of the respective non-driving rear wheel
(figures 2 et 3) par l'intermédiaire d'un boulon étanche 32. La roue comprend une jante 33 sur laquelle est monté un pneumatique 34. Le conduit axial 30 débouche, du côté opposé de la jante 33, dans un distributeur 50 dont la structure sera explicitée ultérieurement en référence aux figures 5 et 6.(Figures 2 and 3) by means of a tight bolt 32. The wheel comprises a rim 33 on which a tire is mounted 34. The axial duct 30 opens, on the opposite side of the rim 33, into a distributor 50, the structure of which will be explained later with reference to FIGS. 5 and 6.
Une sortie 53 du distributeur 50 est reliée, par une tubulureAn outlet 53 of the distributor 50 is connected, by a tube
35, maintenue par un collier 35' , à une valve de gonflage 36 du pneumatique 34 et l'autre sortie 54 du distributeur 50 est reliée, par une tubulure 37, maintenue par un collier 37', à une valve 38 de prise de la pression dans le pneumatique 34.35, held by a collar 35 ', to an inflation valve 36 of the tire 34 and the other outlet 54 of the distributor 50 is connected, by a tube 37, maintained by a collar 37', to a valve 38 for taking the tire pressure 34.
Le distributeur 50 est fixé sur la jante 33 par des ressorts 39 ou par tout autre moyen, par exemple par des boulons ?The distributor 50 is fixed to the rim 33 by springs 39 or by any other means, for example by bolts?
Dans le cas d'une roue avant motrice directrice (figure 4), la tubulure 15 ou 16 débouche dans le conduit axial 30, qui est percé dans le cardan 40 formant alors l'axe de la roue, par l'intermédiaire d'un bouton étanche 41 vissé, à travers la fuséeIn the case of a driving front driving wheel (FIG. 4), the tubing 15 or 16 opens into the axial duct 30, which is drilled in the gimbal 40 then forming the axis of the wheel, by means of a waterproof button 41 screwed through the rocket
42, dans une pièce 43, fixe, entre les roulements, sur la fusée42, in a part 43, fixed, between the bearings, on the spindle
42, avec interposition de bagues de roulements 44 et 45. Le boulon 41 débouche sur un perçage radial 46 de la pièce 43. Le perçage radial 46 débouche dans une rainure annulaire délimitée latéralement par les bagues 44 et 45. Dans sa portion bordant intérieurement la chambre annulaire 47, le cardan 40 est muni d'au moins un alésage radial 48 débouchant dans le conduit axial 30.42, with the interposition of bearing rings 44 and 45. The bolt 41 opens onto a radial bore 46 of the part 43. The radial bore 46 opens into an annular groove delimited laterally by the rings 44 and 45. In its portion internally bordering the annular chamber 47, the gimbal 40 is provided with at least one radial bore 48 opening into the axial duct 30.
On se réfère maintenant aux figures 5 et 6 représentant le distributeur 50.Reference is now made to FIGS. 5 and 6 showing the distributor 50.
Le distributeur 50 comprend un boîtier 51 fixé à la jante de roue par les ressorts 39 et qui tourne donc avec la roue. Le boîtier 51 est fermé sur sa face extérieure par un couvercle 60 fixé par des vis 61. La face extérieure du boîtier 51 est fermée par une plaque 62 formant fond, fixée par des boulons 63 vissés dans des alésages 64 de la plaque 62 et des alésages 65 du boîtier 51.The distributor 50 comprises a housing 51 fixed to the wheel rim by the springs 39 and which therefore rotates with the wheel. The housing 51 is closed on its external face by a cover 60 fixed by screws 61. The external face of the housing 51 is closed by a plate 62 forming the bottom, fixed by bolts 63 screwed in bores 64 of the plate 62 and in the bores 65 of the housing 51.
Un tube 66 formant garniture de raccordement et de distribution est monté pivotant à travers la plaque 62. Le tube 66 comporte une portion élargie 67, fermée à son extrémité écartée de la plaque 62 et tourillonnant dans une cheminée 68 du boîtier 51, avec interposition d'un joint 69, et munie de segments 70 et d'orifices radiaux 71. De l'autre côté de la plaque 62, le tube 66 a une portion 72 extérieure de section réduite munie de joints d'étanchéité 73 de manière à former un embout d'adaptation sur le conduit 30.A tube 66 forming a connection and distribution lining is pivotally mounted through the plate 62. The tube 66 has an enlarged portion 67, closed at its end separated from the plate 62 and journalling in a chimney 68 of the housing 51, with interposition of 'A seal 69, and provided with segments 70 and radial orifices 71. On the other side of the plate 62, the tube 66 has an outer portion 72 of reduced section provided with seals 73 so as to form a adapter piece on the duct 30.
Dans le boîtier 51 est montée une pièce 80 de distribution, dans laquelle est formé un canal 81 dont une extrémité débouche dans le raccord de sortie 53 relié à la tubulure 35 de gonflage. L'autre extrémité 82 du canal 81 débouche dans la cheminée 68, en regard des orifices 71 du tube 66.In the housing 51 is mounted a distribution piece 80, in which a channel 81 is formed, one end of which opens into the outlet connector 53 connected to the inflation tube 35. The other end 82 of the channel 81 opens into the chimney 68, opposite the orifices 71 of the tube 66.
Le canal 81 est coupé par un alésage 83 dans lequel coulisse un piston 84, soumis à l'action d'un ressort 85 taré, qui est muni d'une rainure annulaire périphérique 86. L'alésage 83 débouche à l'extérieur de la pièce 80, dans l'embout de sortie 54 relié à la tubulure 37 de prise de pression.The channel 81 is cut by a bore 83 in which slides a piston 84, subjected to the action of a calibrated spring 85, which is provided with a peripheral annular groove 86. The bore 83 opens outside the part 80, in the outlet nozzle 54 connected to the pressure take-off pipe 37.
Le fonctionnement de l'ensemble qui vient d'être décrit est le suivant.The operation of the assembly which has just been described is as follows.
Le compresseur 3 envoie en permanence de l'air comprimé dans le réservoir 5 dont la pression maximale est limitée par la valve de surpression 17. De l'air sous pression est en conséquence disponible en permanence à l'entrée de la vanne distributrice 7.The compressor 3 continuously sends compressed air to the reservoir 5, the maximum pressure of which is limited by the pressure relief valve 17. Pressurized air is therefore permanently available at the inlet of the distribution valve 7.
Lorsque le conducteur veut mesurer la pression des pneumatiques et éventuellement les regonfler, il actionne la télécommande 19. La vanne distributrice 7 envoie alors de l'air sous pression dans les tubulures 12, 1 3 , 15 et 16 et, de là, dans les conduits axiaux 30 correspondants. L'air sous pression arrive dans chaque distributeur 50, par l'intermédiaire de l'embout 72, et sort dans la cheminée 68 par les orifices 71 d'où il arrive dans le canal 82.When the driver wants to measure the pressure of the tires and possibly re-inflate them, he actuates the remote control 19. The distributor valve 7 then sends pressurized air into the pipes 12, 13, 15 and 16 and, from there, into the corresponding axial conduits 30. The pressurized air arrives in each distributor 50, via the end piece 72, and leaves the chimney 68 through the orifices 71 from where it arrives in the channel 82.
Si la pression dans le pneumatique est supérieure à une valeur prédéterminée correspondant au tarage du ressort 85, le piston 84 est repoussé, contre l'action du ressort 85, de sorte que la rainure 86 n'est pas en regard d canal 81 (position représentée à la figure 6) .If the pressure in the tire is greater than a predetermined value corresponding to the calibration of the spring 85, the piston 84 is pushed back against the action of the spring 85, so that the groove 86 is not opposite the channel 81 (position shown in Figure 6).
Si, au contraire, la pression dans le pneumatique est inférieure à cette valeur prédéterminée, le ressort 85 repousse le piston 84 vers la gauche (dans la figure 6) et la rainure 86 vient en correspondance du canal 81 et l'air comprimé arrive à la sortie 53 pour regonfler le pneumatique à travers la tubulure 35 et la valve de gonflage 36.If, on the contrary, the pressure in the tire is lower than this predetermined value, the spring 85 pushes the piston 84 to the left (in FIG. 6) and the groove 86 comes in correspondence with the channel 81 and the compressed air arrives at the outlet 53 for re-inflating the tire through the tubing 35 and the inflation valve 36.
Lorsque la pression dans le pneumatique atteint à nouveau la valeur prédéterminée, le ressort 85 cesse de repousser le piston 84, l'alimentation de la valve de gonflage 36 est interrompue. When the pressure in the tire again reaches the predetermined value, the spring 85 ceases to push the piston 84, the supply of the inflation valve 36 is interrupted.
