Description
Dispositif d'alimentation en air d'un moteur de véhiculeDevice for supplying air to a vehicle engine
L'invention a pour objet un dispositif d'alimentation en air d'un moteur de véhicule, en particulier un moteur à combustion interne. The subject of the invention is an air supply device for a vehicle engine, in particular an internal combustion engine.
Un moteur de véhicule, en particulier à combustion interne, doit être alimenté en air en passant par un filtre à air qui comporte un circuit amont d'alimentation en air prélevé, habituellement, à l'avant du véhicule et un circuit aval de liaison avec le moteur. A vehicle engine, in particular an internal combustion engine, must be supplied with air via an air filter which comprises an upstream air supply circuit taken, usually at the front of the vehicle and a downstream link circuit with engine.
Habituellement, le filtre à air est placé à la partie supérieure du moteur, et donc recouvert par le capot du véhicule. Cependant, le filtre à air est parfois plus complexe et, dans ce cas, peut être placé sur un côté du moteur et relié, par un circuit amont, à un organe d'entrée d'air, par exemple une écope. Usually, the air filter is placed at the top of the engine, and thus covered by the hood of the vehicle. However, the air filter is sometimes more complex and, in this case, can be placed on one side of the engine and connected by an upstream circuit to an air inlet member, for example a scoop.
Depuis un certain temps, pour améliorer la sécurité et, en particulier, éviter que l'ensemble mécanique soit repoussé dans l'habitacle en cas d'accident, la caisse du véhicule forme, à l'avant, un compartiment pour le moteur capable de résister aux chocs importants en se déformant de façon à absorber l'énergie. For some time, to improve safety and, in particular, prevent the mechanical assembly is pushed into the passenger compartment in case of accident, the vehicle body forms, at the front, a compartment for the engine capable of withstand significant shocks by deforming to absorb energy.
Cependant, un tel compartiment résistant peut être dangereux pour un piéton ou un cycliste heurté par le véhicule. C'est pourquoi, il est maintenant recommandé d'entourer le compartiment moteur d'un volume creux formant la calandre et les ailes et capable de se déformer en cas de choc relativement léger, par exemple avec un piéton, afin d'absorber l'énergie et de réduire les dommages éventuels. However, such a resistant compartment can be dangerous for a pedestrian or cyclist hit by the vehicle. Therefore, it is now recommended to surround the engine compartment with a hollow volume forming the calender and wings and able to deform in case of relatively light impact, for example with a pedestrian, to absorb the energy and reduce possible damage.
Le capot de fermeture du moteur, peut également être formé de façon à constituer, au-dessus des différents organes, évidemment rigides, du moteur, un espace déformable capable d'absorber des chocs venant du haut mais ceci conduit à augmenter la hauteur du capot et le volume global de la partie avant du véhicule. The closing cap of the engine, can also be formed so as to constitute, above the various members, obviously rigid, the engine, a deformable space capable of absorbing shocks coming from above but this leads to increase the height of the hood and the overall volume of the front of the vehicle.
On a proposé, dans le document DE-A-10063778, de placer au-dessus du moteur un filtre à air réalisé lui-même de façon déformable afin d'absorber des chocs de moyenne intensité, par exemple avec un piéton projeté sur le capot. Cependant, un tel filtre à air est relativement onéreux et, bien entendu, doit être remplacé en cas de choc. In document DE-A-10063778, it has been proposed to place above the engine an air filter which itself is deformably made in order to absorb medium-intensity shocks, for example with a pedestrian projected on the hood. . However, such an air filter is relatively expensive and, of course, must be replaced in case of shock.
L'invention a pour objet une disposition plus simple et moins onéreuse permettant d'utiliser judicieusement l'espace de sécurité qui doit être ménagé autour du compartiment moteur. The object of the invention is a simpler and less expensive arrangement making it possible to judiciously use the safety space that must be provided around the engine compartment.
Conformément à l'invention, au moins une partie du circuit amont d'admission d'air dans le filtre à air est réalisée de façon à pouvoir se déformer en cas de choc et placée dans une partie de l'espace de sécurité, de préférence au-dessous du capot de fermeture du compartiment moteur. According to the invention, at least a portion of the upstream air intake circuit in the air filter is made so as to be deformable in the event of impact and placed in a part of the safety space, preferably below the engine compartment closing cover.
Dans un mode de réalisation préférentiel, le circuit amont d'admission d'air comporte un organe d'entrée d'air frais relié au filtre à air par un conduit de liaison réalisé en une matière déformable et s'étendant au moins en partie, au-dessous du capot de fermeture du compartiment moteur. In a preferred embodiment, the upstream air intake circuit comprises a fresh air inlet member connected to the air filter by a connecting duct made of a deformable material and extending at least in part, below the engine compartment closing cover.
Avantageusement, le filtre à air et l'organe d'entrée d'air sont alors reliés chacun à une extrémité du conduit de liaison par un organe de branchement amovible permettant au conduit de liaison de rester solidaire du capot lors de l'ouverture de celui-ci et de se rebrancher automatiquement à ses extrémités, lors de la fermeture du capot. Advantageously, the air filter and the air inlet member are then each connected to one end of the connecting pipe by a removable connection member allowing the connecting pipe to remain attached to the hood when opening the one and automatically reconnect at its ends, when closing the cover.
De façon particulièrement avantageuse, le filtre à air et l'organe d'entrée d'air sont placés respectivement sur deux côtés latéraux opposés du compartiment moteur et reliés chacun, par un organe de branchement amovible, à un conduit de liaison s'étendant transversalement sous le capot. De préférence, chaque organe de branchement amovible comporte deux parties reliées par un tube de liaison déformable et fixées, l'une sur une extrémité du conduit de liaison et l'autre sur l'organe d'entrée d'air ou, respectivement, sur le filtre à air. Particularly advantageously, the air filter and the air inlet member are respectively placed on two opposite lateral sides of the engine compartment and each connected, by a removable branch member, to a transversely extending connecting pipe. under the hood. Preferably, each removable connection member comprises two parts connected by a deformable connecting tube and fixed, one on one end of the connecting duct and the other on the air inlet member or, respectively, on the air filter.
De préférence, le conduit de liaison est fixé sur une face inférieure du capot et comporte, à chaque extrémité, un orifice, respectivement d'entrée ou de sortie, prolongé par un tube de liaison déformable ayant une extrémité qui s'emmanche, à la fermeture du capot, dans un orifice, respectivement, de l'organe d'entrée d'air ou du filtre à air. Preferably, the connecting duct is fixed on a lower face of the hood and comprises, at each end, an orifice, respectively inlet or outlet, extended by a deformable connecting tube having an end which is enclosed, at the closing the cover, in an orifice, respectively, of the air intake member or the air filter.
Avantageusement, le filtre à air est placé à l'intérieur du compartiment moteur et l'organe d'entrée d'air est placé à l'avant du véhicule, à l'extérieur du compartiment moteur, dans une aile ou dans la calandre, et relié par un conduit traversant la paroi du compartiment moteur, à un organe de branchement sur une extrémité amont du conduit de liaison. Advantageously, the air filter is placed inside the engine compartment and the air intake member is placed at the front of the vehicle, outside the engine compartment, in a wing or in the shell, and connected by a duct passing through the wall of the engine compartment to a branch member on an upstream end of the connecting duct.
Par ailleurs, le dispositif comporte avantageusement des artifices acoustiques branchés en dérivation sur le conduit de liaison, pour la réduction du bruit au d'admission du moteur, ces artifices étant déformables en cas de choc. Furthermore, the device advantageously comprises acoustic devices connected bypass on the connecting duct, for the reduction of noise at the intake of the engine, these devices being deformable in case of impact.
D'autres caractéristiques avantageuses de l'invention apparaîtront dans la description qui va suivre d'un mode de réalisation particulier, donné à titre d'exemple et représenté sur les dessins annexés. Other advantageous features of the invention will appear in the following description of a particular embodiment, given by way of example and shown in the accompanying drawings.
La figure 1 est une vue schématique, en perspective, de la partie avant d'un véhicule muni d'un dispositif selon l'invention. Figure 1 is a schematic perspective view of the front portion of a vehicle provided with a device according to the invention.
La figure 2 montre, en perspective, un premier système de branchement. Figure 2 shows, in perspective, a first branch system.
La figure 3 et la figure 4 montrent, avec des coupes partielles, deux autres systèmes de branchement amovibles. Figure 3 and Figure 4 show, with partial sections, two other removable branch systems.
Sur la figure 1 on a représenté, en perspective, la partie avant d'un véhicule 1 comportant un compartiment moteur 10 dans lequel est placé l'ensemble du mécanisme, en particulier le moteur non représenté sur la figure, ce compartiment étant entouré par une calandre 11 et deux ailes 12, 12' et fermé par un capot 13. FIG. 1 shows, in perspective, the front part of a vehicle 1 comprising a motor compartment 10 in which is placed the whole of the mechanism, in particular the motor not shown in the figure, this compartment being surrounded by a calender 11 and two wings 12, 12 'and closed by a hood 13.
Comme on l'a indiqué, les deux ailes 12, 12' et la calandre 11 forment, autour du compartiment moteur, un espace de sécurité réalisé de façon à se déformer en cas de choc de moyenne intensité, pour absorber l'énergie. As indicated, the two wings 12, 12 'and the shell 11 form, around the engine compartment, a safety space made to deform in case of shock of medium intensity, to absorb energy.
De même, le capot 13, lorsqu'il est fermé, présente une rigidité contrôlée de façon à former, au-dessus du moteur, un espace de sécurité relativement déformable en cas de choc. Similarly, the cover 13, when closed, has a rigidity controlled so as to form, above the engine, a relatively deformable safety space in case of impact.
Le moteur est équipé d'un filtre à air 2 qui, de préférence, peut être placé à l'intérieur du compartiment moteur mais à l'arrière et dans un angle de celui-ci, de la façon représentée schématiquement sur la figure 1. Ce filtre à air est donc relié, par un circuit aval non représenté, au moteur et par un circuit amont à un organe d'entrée d'air 3 qui peut être constitué d'une écope de type connu et est placé, de préférence, dans la partie avant du véhicule. The engine is equipped with an air filter 2 which preferably can be placed inside the engine compartment but at the rear and at an angle thereof, as shown diagrammatically in FIG. This air filter is thus connected by a downstream circuit not shown to the engine and by an upstream circuit to an air inlet member 3 which may consist of a scoop of known type and is preferably placed in the front part of the vehicle.
Cette écope 3 peut être réalisée en un matériau relativement léger et déformable, par exemple dans une matière plastique, et peut donc être placée à l'extérieur du compartiment moteur dans l'espace de sécurité constitué par la calandre 11 et les deux ailes 12, 12'. Par exemple, dans l'exemple représenté, l'organe d'entrée d'air 3 est placé à l'avant de l'une des ailes 12 et du côté opposé à celui du filtre à air 2. This scoop 3 can be made of a relatively light and deformable material, for example in a plastic material, and can therefore be placed outside the engine compartment in the safety space constituted by the shell 11 and the two wings 12, 12 '. For example, in the example shown, the air intake member 3 is placed in front of one of the flanges 12 and the side opposite to that of the air filter 2.
L'organe d'entrée d'air 3 et le filtre à air 2 doivent donc être reliés par un conduit de liaison 4 qui, selon l'invention, est fixé sur la face inférieure 13' du capot 13. The air intake member 3 and the air filter 2 must therefore be connected by a connecting duct 4 which, according to the invention, is fixed on the lower face 13 'of the cover 13.
Comme représenté sur les figures 3 et 4, ce capot 13 est réalisé de façon à pouvoir se déformer, en cas de choc, sur une distance de sécurité d, avant d'atteindre une surface limite 10' du compartiment 10 du moteur, appelée nappe du piéton , afin qu'un piéton heurté par le véhicule ne risque pas d'atteindre des parties dures et indéformables du moteur, ce dernier étant, ainsi, entouré d'un espace de sécurité 5. As shown in FIGS. 3 and 4, this hood 13 is designed so that it can be deformed, in the event of impact, over a safety distance d, before reaching a limit surface 10 'of the compartment 10 of the engine, referred to as the the pedestrian, so that a pedestrian struck by the vehicle does not risk reaching hard and indeformable parts of the engine, the latter being, thus, surrounded by a safety space 5.
Selon l'invention, le conduit de liaison 4 s'étend donc au-dessous du capot 13 dans cet espace de sécurité 5 et présente, de préférence, une section oblongue permettant d'assurer le débit d'air nécessaire avec une épaisseur e, inférieure à la distance de sécurité d. According to the invention, the connecting duct 4 thus extends below the cover 13 in this safety space 5 and preferably has an oblong section to ensure the necessary air flow with a thickness e, less than the safety distance d.
Pour permettre l'ouverture et la fermeture du capot, le conduit de liaison 4 est muni à chacune de ses extrémités, respectivement amont et aval, d'un organe de branchement amovible 6, 6'. Dans le mode de réalisation le plus simple représenté sur la figure 2, chaque organe de branchement est constitué de deux parties s'emboîtant l'une dans l'autre, par exemple de forme tronconique, respectivement en amont une partie mâle 61 entourant un orifice d'entrée 41 du conduit de liaison 4 et s'emboîtant dans une partie creuse 62, reliée à un conduit 31 de sortie de l'organe 3 d'alimentation en air et, en aval, une partie mâle 61' entourant l'orifice de sortie 42 et s'emboîtant dans une partie creuse 62' reliée à un conduit 21 d'entrée dans le filtre à air 2. To allow the opening and closing of the cover, the connecting pipe 4 is provided at each of its ends, respectively upstream and downstream, a removable branch member 6, 6 '. In the simplest embodiment shown in FIG. 2, each branching member consists of two parts fitting one into the other, for example of frustoconical shape, respectively upstream of a male part 61 surrounding an orifice. input 41 of the connecting duct 4 and fitting into a hollow portion 62, connected to a conduit 31 for output of the air supply member 3 and, downstream, a male portion 61 'surrounding the orifice outlet 42 and fitting into a hollow portion 62 'connected to an inlet duct 21 in the air filter 2.
Ces conduits 31, 21 peuvent être réalisés en une matière souple de façon à se déformer en cas de choc. Toutefois, dans le mode de réalisation représenté schématiquement sur la figure 3, chaque orifice, respectivement d'entrée 41 ou de sortie 42 du conduit de liaison 4 est relié à un orifice correspondant de l'organe d'alimentation 3 ou du filtre 2 par un conduit flexible 63, par exemple à soufflets, ayant une extrémité 63a fixée, par exemple par enfilement, sur une partie correspondante entourant l'orifice de sortie 42 du conduit 4 et une seconde extrémité 63b qui peut avoir, par exemple, une forme évasée de façon à se brancher de façon amovible sur une partie correspondante 23 du filtre à air 2, à la fermeture du capot. These ducts 31, 21 may be made of a flexible material so as to deform in case of impact. However, in the embodiment shown diagrammatically in FIG. 3, each orifice, respectively inlet 41 or outlet 42, of the connecting duct 4 is connected to a corresponding orifice of the supply member 3 or the filter 2 by a flexible duct 63, for example with bellows, having an end 63a fixed, for example by threading, on a corresponding part surrounding the outlet orifice 42 of the duct 4 and a second end 63b which may have, for example, a flared shape so as to connect removably to a corresponding portion 23 of the air filter 2, closing the hood.
Bien entendu, la même disposition peut être adoptée pour l'orifice d'entrée 41 du conduit de liaison 4. Of course, the same arrangement can be adopted for the inlet port 41 of the connecting pipe 4.
La figure 4 montre encore un autre exemple de réalisation dans lequel chaque orifice, respectivement d'entrée, 41 ou de sortie 42, du conduit de liaison 4 est prolongé par un tube déformable 64 muni, à son extrémité libre, d'une pièce d'interface 65 de forme torique qui vient s'appliquer, à la fermeture du capot, dans une partie évasée 24 entourant l'orifice d'entrée du filtre à air 2, la disposition étant analogue pour l'écope d'admission 3. FIG. 4 shows yet another embodiment in which each orifice, respectively inlet 41 or outlet 42, of the connecting conduit 4 is extended by a deformable tube 64 provided at its free end with a piece of O-shaped interface 65 which is applied, when the cover is closed, in a flared part 24 surrounding the inlet orifice of the air filter 2, the arrangement being similar for the intake scoop 3.
De plus, comme le montrent les figures, le conduit de liaison 4 présente, de préférence, une forme aplatie avec une section transversale oblongue et peut ainsi suivre une déformation du capot 13 en cas de choc, en restant dans la zone de sécurité 5. In addition, as shown in the figures, the connecting duct 4 preferably has a flattened shape with an oblong cross section and can thus follow a deformation of the cover 13 in the event of an impact, while remaining in the safety zone 5.
Par ailleurs, des artifices acoustiques 45, représentés schématiquement sur la figure 4, peuvent avantageusement être placés sur le trajet du conduit de liaison 4, en nombre plus ou moins important, de tels artifices pouvant être d'un type connu permettant de réduire le bruit du moteur. Moreover, acoustic devices 45, shown schematically in FIG. 4, can advantageously be placed in the path of the connecting duct 4, in more or less significant numbers, such devices being able to be of a known type making it possible to reduce noise. of the motor.
De préférence, les pièces du système seront réalisées de façon à participer à la raideur du capot et, donc, à l'absorption de l'énergie. Preferably, the parts of the system will be made to participate in the stiffness of the hood and, therefore, the absorption of energy.
La forme et la nature des différents organes, en particulier du conduit de liaison 4, peuvent varier en fonction de la motorisation. Pour participer à l'absorption de l'énergie, le conduit de liaison peut être réalisé en une matière poreuse souple, ou bien une matière rigide à écrasement programmé. The shape and nature of the various members, in particular the connecting duct 4, may vary depending on the motorization. To participate in the absorption of energy, the connecting conduit may be made of a flexible porous material, or a rigid material with programmed crushing.
Bien entendu, l'invention ne se limite pas aux détails du mode de réalisation et des variantes qui n'ont été décrits schématiquement qu'à titre d'exemple, d'autres dispositions équivalentes pouvant être employées sans s'écarter du cadre de protection de l'invention. Of course, the invention is not limited to the details of the embodiment and the variants which have been described schematically only by way of example, other equivalent arrangements that can be used without departing from the protective frame of the invention.
En particulier, la forme du conduit de liaison 4 représenté schématiquement sur la figure 1 peut être modifiée pour s'adapter aux positions de l'écope d'admission d'air 3 et du filtre à air 2 qui peuvent varier en fonction du type du véhicule et des possibilités d'implantation autour du compartiment moteur ou à l'intérieur de celui-ci pour certains organes. In particular, the shape of the connecting duct 4 shown diagrammatically in FIG. 1 can be modified to adapt to the positions of the air intake duct 3 and the air filter 2 which can vary according to the type of the duct. vehicle and possibilities of implantation around the engine compartment or inside it for some organs.
