Description

VEHICULE AUTOMOBILE DONT LE DESSOUS DE LA CAISSE EST EQUIPE D'UN DEVIATEUR AERODYNAMIQUE  MOTOR VEHICLE WITH BELOW BODY EQUIPPED WITH AERODYNAMIC DEVIATOR
La présente invention concerne un véhicule automobile dont le dessous de la caisse est équipé d'un déviateur aérodynamique. The present invention relates to a motor vehicle whose underside of the body is equipped with an aerodynamic deflector.
La figure 1 représente schématiquement en coupe longitudinale partielle le dessous de la caisse d'un véhicule automobile.  Figure 1 shows schematically in partial longitudinal section the underside of the body of a motor vehicle.
Dans cet exemple, le véhicule comprend un train arrière dont la traverse 1 s'étend sous le plancher 2 de la caisse.  In this example, the vehicle comprises a rear axle whose cross 1 extends below the floor 2 of the body.
Cette traverse 1 fait saillie sous le plancher et constitue un obstacle par rapport au flux aérodynamique 3 engendré lors du roulage du véhicule dans la direction montrée par la flèche D.  This crossbar 1 protrudes under the floor and is an obstacle compared to the aerodynamic flow 3 generated during the driving of the vehicle in the direction shown by the arrow D.
Cet obstacle augmente le Cx du véhicule et par conséquent la consommation et les rejets de C02et de gaz polluants du véhicule. This obstacle increases the Cx of the vehicle and consequently the consumption and the releases of C0 2 and pollutant gases of the vehicle.
D'autres obstacles que la traverse 1 peuvent exister sous le plancher 2 du véhicule.  Other obstacles than the crossbar 1 may exist under the floor 2 of the vehicle.
Un tel obstacle peut être constitué par la planche à talon qui fait saillie sous le dessous de la caisse dans certains véhicules.  Such an obstacle can be constituted by the heel board which protrudes under the underside of the body in certain vehicles.
On remarque, par ailleurs, que le véhicule, représenté sur la figure 1 , comporte un tube d'échappement 4 s'étendant sensiblement parallèlement à l'axe longitudinal du véhicule dans l'espace compris entre le plancher 2 et la traverse 1.  Note also that the vehicle, shown in Figure 1, comprises an exhaust tube 4 extending substantially parallel to the longitudinal axis of the vehicle in the space between the floor 2 and the cross 1.
Le but de la présente invention est de remédier aux inconvénients engendrés par des obstacles tels que les parties faisant saillie citées plus haut.  The object of the present invention is to overcome the disadvantages caused by obstacles such as protruding parts mentioned above.
Ce but est atteint, selon l'invention, grâce à un véhicule automobile comportant d'une part une partie faisant saillie sous le dessous de la caisse et s'étendant transversalement par rapport à la direction longitudinale du véhicule, de telle sorte que cette partie faisant saillie constitue un obstacle par rapport au flux aérodynamique engendré lors du roulage du véhicule et d'autre part, un tube d'échappement, caractérisé en ce que le tube d'échappement porte, dans une zone située devant ladite partie faisant saillie, une plaque capable de dévier ledit flux aérodynamique par rapport à ladite partie faisant saillie.  This object is achieved, according to the invention, by means of a motor vehicle comprising on the one hand a part projecting under the underside of the body and extending transversely with respect to the longitudinal direction of the vehicle, so that this part protruding constitutes an obstacle with respect to the aerodynamic flow generated during the running of the vehicle and secondly, an exhaust tube, characterized in that the exhaust tube carries, in an area situated in front of said protruding part, a plate capable of deflecting said aerodynamic flow with respect to said projecting portion.
Le fait que la plaque portée par le tube d'échappement puisse dévier le flux aérodynamique par rapport à la partie faisant saillie sous le véhicule permet d'éviter que celle-ci constitue un frein aérodynamique ayant des effets négatifs à l'égard de la consommation et des rejets du véhicule. The fact that the plate carried by the exhaust tube can deflect the aerodynamic flow with respect to the part projecting under the vehicle allows to avoid that it constitutes an aerodynamic brake having negative effects with respect to the consumption and rejections of the vehicle.
Par ailleurs, il a été constaté que le tube d'échappement constituait un excellent support pour la plaque formant déviateur aérodynamique.  Furthermore, it was found that the exhaust tube was an excellent support for the aerodynamic deflector plate.
Dans une application préférée de l'invention, ladite partie faisant saillie est la traverse qui relie entre elles les deux roues du train arrière.  In a preferred application of the invention, said protruding portion is the cross member which connects the two wheels of the rear axle.
Dans une autre application préférée, ladite partie faisant saillie est la planche à talon.  In another preferred application, said projecting portion is the heel board.
Dans les deux cas, la plaque portée par le tube d'échappement dévie le flux aérodynamique pour éviter que celui-ci impacte la traverse du train arrière ou la planche à talon.  In both cases, the plate carried by the exhaust tube deflects the aerodynamic flow to prevent it from impacting the cross of the rear axle or the heel board.
De préférence également, la plaque portée par le tube d'échappement est agencée pour pouvoir dévier ledit flux aérodynamique sous ladite partie faisant saillie.  Also preferably, the plate carried by the exhaust tube is arranged to be able to deflect said aerodynamic flow under said projecting portion.
Dans un mode de réalisation avantageux de l'invention, ladite plaque a une surface supérieure à celle de la section du tube d'échappement.  In an advantageous embodiment of the invention, said plate has a surface greater than that of the section of the exhaust tube.
Dans un mode de réalisation particulièrement avantageux de l'invention, ladite plaque est en tôle et comprend deux parties pliées l'une par rapport à l'autre, la première partie de la plaque étant fixée au tube d'échappement et étant située dans un plan sensiblement perpendiculaire audit tube d'échappement et la seconde partie de la plaque formant avec la première partie un angle obtus ouvert vers ladite partie en saillie.  In a particularly advantageous embodiment of the invention, said plate is made of sheet metal and comprises two parts bent with respect to each other, the first part of the plate being fixed to the exhaust tube and being located in a plane substantially perpendicular to said exhaust tube and the second part of the plate forming with the first part an obtuse angle open towards said projecting portion.
Selon d'autres particularités avantageuses de l'invention :  According to other advantageous features of the invention:
- la première partie de la plaque comprend une encoche en forme de demi- cercle engagée sur ledit tube d'échappement et fixée à ce dernier en trois points angulairement espacés ;  the first part of the plate comprises a notch in the shape of a semi-circle engaged on said exhaust tube and fixed thereto at three angularly spaced points;
- ledit tube d'échappement comprend une partie courbe qui passe au- dessus de la traverse du train arrière, ladite plaque étant située devant la traverse près de l'extrémité avant de ladite partie courbe du tube d'échappement.  said exhaust tube comprises a curved portion which passes over the cross member of the rear axle, said plate being located in front of the cross member near the front end of said curved portion of the exhaust tube.
D'autres particularités et avantages de l'invention apparaîtront encore tout au long de la description ci-après.  Other features and advantages of the invention will become apparent throughout the description below.
Aux dessins annexés, donnés à titre d'exemples, non limitatifs : - la figure 2 est une vue analogue à la figure 1 montrant le déviateur aérodynamique fixé conformément à l'invention au tube d'échappement du véhicule automobile, In the accompanying drawings, given by way of nonlimiting examples: FIG. 2 is a view similar to FIG. 1 showing the aerodynamic deflector fixed according to the invention to the exhaust pipe of the motor vehicle,
- la figure 3 est une vue en perspective montrant le tube d'échappement et la plaque formant déviateur fixée au tube,  FIG. 3 is a perspective view showing the exhaust tube and the deflector plate attached to the tube;
- la figure 4 est une autre vue en perspective montrant la plaque formant déviateur seule,  FIG. 4 is another perspective view showing the plate forming a deflector alone,
- la figure 5 est une vue partielle montrant le dessous de la caisse d'un véhicule automobile, le tube d'échappement et sa plaque formant déviateur, ainsi que la traverse du train arrière.  - Figure 5 is a partial view showing the underside of the body of a motor vehicle, the exhaust tube and its deflector plate, and the cross of the rear axle.
La figure 2 représente schématiquement une partie d'un véhicule automobile comportant une traverse de train arrière 1 faisant saillie sous le plancher 2 de la caisse et s'étendant transversalement par rapport à la direction longitudinale du véhicule, de telle sorte que cette traverse 1 constitue un obstacle par rapport au flux aérodynamique engendré lors du roulage du véhicule.  FIG. 2 diagrammatically represents a portion of a motor vehicle comprising a rear axle cross member 1 protruding under the floor 2 of the body and extending transversely with respect to the longitudinal direction of the vehicle, so that this crosspiece 1 constitutes an obstacle compared to the aerodynamic flow generated during the running of the vehicle.
Le véhicule comprend en outre un tube d'échappement 4 s'étendant sensiblement parallèlement à l'axe longitudinal du véhicule.  The vehicle further comprises an exhaust tube 4 extending substantially parallel to the longitudinal axis of the vehicle.
Conformément à l'invention, le tube d'échappement 4 porte, dans une zone située devant la traverse 1 du train arrière, une plaque 5 capable de dévier le flux aérodynamique 6 par rapport à la traverse 1.  According to the invention, the exhaust tube 4 carries, in an area located in front of the cross member 1 of the rear axle, a plate 5 capable of deflecting the aerodynamic flow 6 with respect to the crossbar 1.
Dans l'exemple représenté, la plaque 5 est capable de dévier le flux 6 sous la traverse 1.  In the example shown, the plate 5 is capable of deflecting the stream 6 under the crossbar 1.
Les figures 3, 4 et 5 montrent que la plaque 5 a une surface qui est supérieure à celle de la section du tube d'échappement.  Figures 3, 4 and 5 show that the plate 5 has a surface which is greater than that of the section of the exhaust tube.
Cette plaque 5 est de préférence en tôle.  This plate 5 is preferably sheet metal.
De plus, la plaque 5 comprend deux parties 5a, 5b pliées l'une par rapport à l'autre.  In addition, the plate 5 comprises two parts 5a, 5b folded relative to each other.
La première partie 5a de la plaque 5 est fixée au tube d'échappement 4 et est située dans un plan sensiblement perpendiculaire au tube d'échappement 4 et la seconde partie 5b de la plaque 5 forme avec la première partie 5a un angle obtus ouvert vers la traverse 1.  The first part 5a of the plate 5 is fixed to the exhaust tube 4 and is located in a plane substantially perpendicular to the exhaust tube 4 and the second part 5b of the plate 5 forms with the first part 5a an open obtuse angle towards the crossbar 1.
Les figures 3 et 4 montrent en outre que la première partie 5a de la plaque 5 comprend une encoche 7 en forme de demi-cercle engagée sur le tube d'échappement 4 et fixée à ce dernier en trois points 8, 9, 10 angulairement espacés. Figures 3 and 4 further show that the first part 5a of the plate 5 comprises a notch 7 in the form of a semicircle engaged on the tube exhaust 4 and fixed thereto at three points 8, 9, 10 angularly spaced.
De plus, dans l'exemple montré sur la figure 2, le dit tube d'échappement 4 comprend une partie courbe 4a qui passe au-dessus de la traverse 1 du train arrière.  In addition, in the example shown in Figure 2, said exhaust tube 4 comprises a curved portion 4a which passes above the cross 1 of the rear axle.
La plaque 5 est située devant la traverse 1 près de l'extrémité avant de la partie courbe 4a du tube d'échappement 4.  The plate 5 is located in front of the cross member 1 near the front end of the curved portion 4a of the exhaust tube 4.
Lors du roulage du véhicule dans la direction D, un flux aérodynamique 6 (voir figure 2) est créé entre le plancher 2 et le sol.  When driving the vehicle in the direction D, an aerodynamic flow 6 (see Figure 2) is created between the floor 2 and the ground.
Au lieu d'impacter la traverse 1 et de freiner le véhicule, le flux aérodynamique 6 est dévié sous la traverse 1 grâce à la présence de la plaque 5 qui est fixée au tube d'échappement 4 devant la traverse 1.  Instead of impacting the crossbar 1 and braking the vehicle, the aerodynamic flow 6 is deflected under the crossbar 1 thanks to the presence of the plate 5 which is fixed to the exhaust tube 4 in front of the cross 1.
Grâce à la fonction de déviateur remplie par la plaque 5, on réduit la consommation et les émissions de C02 et gaz polluants du véhicule. Thanks to the diverter function filled by the plate 5, the consumption and the emissions of C0 2 and pollutant gases of the vehicle are reduced.
Bien entendu, l'invention peut s'appliquer aux véhicules ayant des parties en saillie sous la caisse autres qu'une traverse de train arrière.  Of course, the invention can be applied to vehicles having parts protruding under the body other than a rear crossbeam.
Ainsi, l'invention peut aussi s'appliquer aux véhicules ayant une planche à talon sous la caisse.  Thus, the invention can also be applied to vehicles having a heel board under the body.
Dans ce cas, il suffit de fixer la plaque de déviation au tube d'échappement devant cette planche à talon.  In this case, simply attach the deflection plate to the exhaust tube in front of the heel board.
