Abstract
Description
La présente invention a pour objet un véhicule automobile comprenant une carrosserie ou coque qu'on appellera la caisse, un moteur à combustion interne supporté par la caisse et un circuit pour l'alimentation en air du moteur, qui comprend un filtre muni d'une enveloppe ayant une ouverture d'entrée et une ouverture de sortie, laquelle est reliée au conduit d'admission du moteur, caractérisé en ce que la partie avant de la caisse comprend un élément creux présentant une paroi munie d'ouvertures qui mettent la cavité de cet élément de la catisse en communication avec l'extérieur, et en ce qu'il est prévu des moyens de liaison pour relier ladite cavité à l'ouverture d'entrée de l'enveloppe du filtre à air d'alimentation du moteur. The subject of the present invention is a motor vehicle comprising a body or shell which will be called the body, an internal combustion engine supported by the body and a circuit for supplying air to the engine, which comprises a filter provided with a envelope having an inlet opening and an outlet opening, which is connected to the engine intake duct, characterized in that the front part of the body comprises a hollow element having a wall provided with openings which put the cavity of this element of the catisse in communication with the outside, and in that there is provided connecting means for connecting said cavity to the inlet opening of the envelope of the engine supply air filter.
Ledit élément creux est de préférence constitué par une traverse en caisson disposée dans la partie avant de la caisse et qui présente une ouverture auxiliaire dans sa paroi arrière, lesdits moyens de- liaison comprenant une canalisation reliée, à une extrémité, à ladite ouverture auxiliaire de la paroi arrière de la traverse et, à l'autre extrémité, à l'ouverture d'entrée du filtre à air d'alimentation du moteur. Said hollow element preferably consists of a box-shaped cross member disposed in the front part of the box and which has an auxiliary opening in its rear wall, said connecting means comprising a pipe connected, at one end, to said auxiliary opening of the rear wall of the cross member and, at the other end, at the inlet opening of the engine supply air filter.
Des études et expériences effectuées par la demanderesse ont montré que la structure et la dlsposition décrite plus haut permettent de reduire sensiblement le bruit du circuit, comparativement aux solutions traditionnelles Zans lesquelles l'enveloppe du filtre à air d'alimentation est munie d'une prise d'air, servant à faire pénétrer l'air dans le filtre, qui communique directement avec le compartiment moteur du véhicule. Studies and experiments carried out by the applicant have shown that the structure and the arrangement described above make it possible to significantly reduce the noise of the circuit, compared to traditional solutions Zans in which the envelope of the supply air filter is provided with a plug. air, used to bring air into the filter, which communicates directly with the engine compartment of the vehicle.
D'autres caractéristiques et avantages de l'invention seront mieux compris à a lecture de la description qui va suivre d'un exemple de réalisation et en se référant aux dessins annexés sur lesquels,
la figure 1 est une vue en perspective schématique qui illustre un véhicule automobile selon l'inven tion
la figure 2 est une vue en perspective à plus grande échelle d'un détail de la figure 1 ; et
la figure 3 est une vue en plan du détail de la figure 2.Other characteristics and advantages of the invention will be better understood on reading the description which follows of an exemplary embodiment and with reference to the appended drawings in which,
Figure 1 is a schematic perspective view which illustrates a motor vehicle according to the invention
Figure 2 is an enlarged perspective view of a detail of Figure 1; and
FIG. 3 is a plan view of the detail of FIG. 2.
Sur la figure 1, le numéro de référence 1 désigne un véhicule automobile comprenant une carrosserie ou caisse 2 qui comprend, à son extrémité avant, une traverse 3 én caisson (voir en particulier la figure 2), constituée par des éléments en tôle 4, 5 qui définissent une cavité intérieure 6. La caisse 2 du véhicule automobile supporte à l'avant le moteur à combustion interne 7 (indiqué seulement schématiquement sur la figure 1), auquel est associé un circuit classique pour l'alimentation en air, lequel comprend un dispositif filtrant 8. In FIG. 1, the reference number 1 designates a motor vehicle comprising a bodywork or body 2 which comprises, at its front end, a cross member 3 made of a box (see in particular FIG. 2), constituted by sheet metal elements 4, 5 which define an interior cavity 6. The body 2 of the motor vehicle supports at the front the internal combustion engine 7 (indicated only diagrammatically in FIG. 1), with which is associated a conventional circuit for air supply, which comprises a filter device 8.
Le dispositif filtrant 8 comprend un élément filtrant 9, qui peut être d'un type connu quelconque (qui est simplement indiqué schématiquement sur la figure 2), et une enveloppe 10 munie d'une ouverture d'entrée 11 et d'une ouverture de sortie 12. Les ouvertures 11, 12 sont respectivement définies par une prise d'air 13 qui fait partie de l'enveloppe 10, et par un élément de raccordement 14 qui est relié au conduit d'admission du moteur (non représenté sur les dessins). The filter device 8 comprises a filter element 9, which can be of any known type (which is simply indicated diagrammatically in FIG. 2), and a casing 10 provided with an inlet opening 11 and an opening for outlet 12. The openings 11, 12 are respectively defined by an air intake 13 which is part of the casing 10, and by a connection element 14 which is connected to the intake duct of the engine (not shown in the drawings ).
L'ouverture d'entrée 11 est reliée par un tuyau souple annelé 15 à une ouverture 16 formée sur une paroi arrière 17 de la traverse en caisson 3. Cette traverse comprend une paroi avant 18 et présente dans sa paroi arrière 17 une série d'ouvertures 19 qui mettent la cavité 16 en communication avec l'extérieur. The inlet opening 11 is connected by a flexible corrugated pipe 15 to an opening 16 formed on a rear wall 17 of the box cross member 3. This cross member comprises a front wall 18 and has in its rear wall 17 a series of openings 19 which put the cavity 16 in communication with the outside.
Pendant le fonctionnement du moteur, l'air pénètre dans la cavité 16 (comme indiqué par les flèches A sur la figure 3) en passant à travers les ouvertures 19 de la paroi arrière 17 de la traverse en caisson 3. La cavité intérieure 16 présente un volume suffisant pour constituer une sorte de "poumon" d'alimentation en air du dispositif filtrant 8. L'air parvient à l'élément filtrant 9 du dispositif 8 en passant par l'ouverture de sortie 16, le tuyau de liaison 15 et la prise d'air 13. During the operation of the engine, the air enters the cavity 16 (as indicated by the arrows A in FIG. 3) by passing through the openings 19 of the rear wall 17 of the box cross member 3. The interior cavity 16 has sufficient volume to constitute a sort of "lung" for supplying air to the filtering device 8. The air reaches the filtering element 9 of the device 8 via the outlet opening 16, the connecting pipe 15 and the air intake 13.
Sur les dessins, on a également représenté une paroi 20, qui fait partie de la caisse 1, et qui présente une ouverture 21 pour le passage du tuyau de liaison 15. In the drawings, there is also shown a wall 20, which is part of the body 1, and which has an opening 21 for the passage of the connecting pipe 15.
Bien entendu, diverses modifications pourront être apportées par l'homme de l'art au disposirtif qui vient d'être décrit uniquement à titre d'exemple non limitatif sans sortir du cadre de l'invention. Of course, various modifications may be made by those skilled in the art to the device which has just been described only by way of nonlimiting example without departing from the scope of the invention.
