Description

Train arrière multi-bras pour véhicule automobile Multi-arm rear axle for a motor vehicle
La présente invention concerne un train arrière multi-bras pour véhicule automobile.The present invention relates to a multi-arm rear axle for a motor vehicle.
La figure 1 représente la structure d'un train arrière connu d'un véhicule automobile.Figure 1 shows the structure of a known rear train of a motor vehicle.
Ce train arrière comprend un porte-fusée 1 portant une roue 2 qui est relié au berceau fixe 3 situé entre les deux roues par des biellettes articulées 4, 5 s'étendant transversalement à l'axe longitudinal du véhicule.This rear axle comprises a knuckle 1 carrying a wheel 2 which is connected to the fixed cradle 3 located between the two wheels by articulated rods 4, 5 extending transversely to the longitudinal axis of the vehicle.
Ces biellettes 4, 5 comprennent une biellette supérieure 4 dite de carrossage s'étendant au-dessus de la ou des biellettes inférieures 5.These rods 4, 5 comprise a camber upper link 4 extending above the lower rod or rods 5.
La ou les biellettes inférieures 5 supportent un ressort 6 et une butée de choc (non représentée). Ce ressort 6 est en appui sous un longeron 7.The lower link or rods 5 support a spring 6 and a shock stop (not shown). This spring 6 is supported under a spar 7.
La biellette inférieure 5 supporte des efforts transversaux entre la roue 2 et le berceau 3 ainsi que des efforts verticaux importants qui sont souvent supérieurs à 10000 N.The lower link 5 supports transverse forces between the wheel 2 and the cradle 3 and large vertical forces that are often greater than 10000 N.
La biellette supérieure 4 a pour fonction principale d'assurer la raideur de carrossage.The upper link 4 has the main function of ensuring camber stiffness.
Cette biellette supérieure 4 s'étendant sous le longeron 7 doit pouvoir débattre en cas de choc sans toucher le longeron 7. De ce fait cette biellette 4 présente la forme cintrée montrée sur la figure 1 et doit être renforcée pour assurer sa fonction principale de rigidité en traction et en compression.This upper link 4 extending under the spar 7 must be able to debate in the event of an impact without touching the spar 7. Therefore this link 4 has the curved shape shown in FIG. 1 and must be reinforced to ensure its main function of rigidity. in traction and compression.
Du fait de sa forme cintrée, la biellette supérieure 4 est coûteuse à fabriquer. Ainsi, cette biellette est généralement réalisée en acier forgé, en fonderie d'aluminium, en acier mécano soudé de forte épaisseur, à partir d'un tube cintré avec des embouts soudés.Because of its curved shape, the upper link 4 is expensive to manufacture. Thus, this rod is generally made of forged steel, aluminum foundry, thick welded steel, from a bent tube with welded ends.
Par ailleurs, dans la structure connue, montrée sur la figure 1 , le ressort 6 s'appuie sur la biellette inférieure 5. L'effort du ressort 6 ne peut pas s'appliquer constamment sur l'axe de la biellette 5, de sorte qu'il génère un couple de rotation autour de l'axe de la biellette, ce qui génère des contraintes supplémentaires aux articulations élastiques de la biellette.Furthermore, in the known structure, shown in Figure 1, the spring 6 is supported on the lower link 5. The force of the spring 6 can not be applied constantly on the axis of the link 5, so it generates a rotation torque around the axis of the rod, which generates additional stresses to the elastic joints of the link.
Le but de la présente invention est de remédier aux inconvénients précités.The object of the present invention is to overcome the aforementioned drawbacks.
Ce but est atteint selon l'invention grâce à un train arrière multi-bras pour véhicule automobile comprenant un porte-fusée qui est relié à un support fixe du véhicule par des biellettes articulées s'étendant transversalement à l'axe longitudinal du véhicule, ces biellettes comprenant au moins une biellette supérieure dite de carrossage s'étendant au-dessus des autres biellettes caractérisé en ce que ladite biellette supérieure est de forme rectiligne entre son point d'articulation au porte-fusée et son point d'articulation au support fixe du véhicule.This object is achieved according to the invention by means of a multi-arm rear axle for a motor vehicle comprising a rocket carrier which is connected to a fixed support of the vehicle by articulated rods extending transversely to the longitudinal axis of the vehicle, these rods comprising at least one said upper camber rod extending above the other rods characterized in that said upper link is of rectilinear shape between its point of articulation to the stub axle and its point of articulation to the fixed support of the vehicle.
Ainsi, la biellette supérieure du fait de sa forme rectiligne est plus simple et moins coûteuse à fabriquer.Thus, the upper link because of its rectilinear shape is simpler and less expensive to manufacture.
Elle peut par exemple être réalisée à partir d'un tube comportant à chacune de ses extrémités, une douille soudée portant une articulation.It may for example be made from a tube having at each of its ends, a welded sleeve bearing a hinge.
En outre, grâce à l'invention, toutes les biellettes du train arrière peuvent être rectilignes entre leurs deux points d'articulation, ce qui permet de simplifier l'ensemble et de réduire considérablement le coût de fabrication.In addition, thanks to the invention, all links of the rear axle can be straight between their two points of articulation, which simplifies the whole and significantly reduce the cost of manufacture.
De préférence, ladite biellette supérieure est articulée au porte-fusée en un point qui est espacé de la face interne du longeron arrière du véhicule, vers le plan médian du véhicule, dans une direction transversale à ce plan.Preferably, said upper link is articulated to the stub axle at a point which is spaced from the inner face of the rear spar of the vehicle, towards the median plane of the vehicle, in a direction transverse to this plane.
Cette disposition permet d'éviter que la biellette supérieure entre en contact avec le longeron lors de son débattement. Ainsi, la biellette n'a pas besoin d'être cintrée. Dans une version préférée de l'invention, le porte-fusée supporte l'ensemble des biellettes et le ressort de suspension.This arrangement prevents the upper link comes into contact with the spar during its travel. Thus, the rod does not need to be bent. In a preferred version of the invention, the rocket carrier supports all the rods and the suspension spring.
Ce porte-fusée peut en outre supporter la butée de choc et l'amortisseur.This knuckle can also support the shock stop and the damper.
Cette disposition permet de réduire les efforts transmis à la ou les biellettes inférieures et de simplifier la fabrication de celles-ci. A cet effet, le porte-fusée peut être réalisé d'une seule pièce en forme de cuve ouverte vers le haut dont le fond supporte notamment le ressort, la paroi latérale de cette cuve portant d'un côté la fusée et le bord supérieur de la paroi latérale de la cuve comportant à l'opposé de la fusée le point d'articulation de la biellette supérieure. Dans une version avantageuse de l'invention, le porte-fusée est relié à deux biellettes inférieures dont les points d'articulation sont situés près du fond de la cuve et de la paroi portant la fusée.This arrangement makes it possible to reduce the forces transmitted to the lower link (s) and to simplify the manufacture thereof. For this purpose, the knuckle can be made in one piece in the form of upwardly open tank whose bottom supports in particular the spring, the side wall of this vessel carrying on one side the rocket and the upper edge of the side wall of the tank having opposite the rocket the point of articulation of the upper link. In an advantageous version of the invention, the knuckle is connected to two lower links whose hinge points are located near the bottom of the tank and the wall carrying the rocket.
Dans cette version, le porte-fusée supporte en outre un bras longitudinal dont l'extrémité opposée au porte-fusée est reliée à une partie fixe du véhicule. Ainsi, l'ensemble des bras et biellettes du train arrière sont rectilignes et peuvent être réalisés de façon simple et peu coûteuse à partir de tubes. D'autres particularités et avantages de l'invention apparaîtront encore tout au long de la description ci-après.In this version, the stub axle also supports a longitudinal arm whose opposite end to the stub axle is connected to a fixed part of the vehicle. Thus, all the arms and rods of the rear axle are straight and can be made simply and inexpensively from tubes. 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 1 est une vue schématique en élévation d'un train arrière de véhicule automobile, selon l'état de la technique, la figure 2 est une vue analogue à la figure 1 , montrant un train arrière selon l'invention, la figure 3 est une vue de dessus de la partie gauche de la figure 2. Dans la réalisation représentée sur la figure 2, le train arrière multi-bras pour véhicule automobile comprend un porte-fusée 8 qui est relié au berceau fixe 3 du véhicule par des biellettes articulées 9, 10, 1 1 s'étendant transversalement à l'axe longitudinal du véhicule.In the accompanying drawings, given by way of nonlimiting example: FIG. 1 is a diagrammatic elevational view of a rear axle of a motor vehicle, according to the state of the art, FIG. 2 is a view similar to FIG. 1, showing a rear axle according to the invention, FIG. 3 is a view from above of the left part of FIG. 2. In the embodiment represented in FIG. 2, the multi-arm rear axle for a motor vehicle comprises a carrier rocket 8 which is connected to the fixed cradle 3 of the vehicle by articulated links 9, 10, 1 1 extending transversely to the longitudinal axis of the vehicle.
Ces biellettes 9, 10, 1 1 comprennent une biellette supérieure 9 dite de carrossage s'étendant au-dessus des deux autres biellettes 10, 1 1. Conformément à l'invention, la biellette supérieure 9 est de forme rectiligne entre son point d'articulation F au porte-fusée 8 et son point d'articulation D au berceau fixe 3 du véhicule.These rods 9, 10, 1 1 comprise an upper camber rod 9 extending over the other two rods 10, 1 1. In accordance with the invention, the upper link 9 is rectilinear between its point of contact. articulation F to the stub axle 8 and its articulation point D to the fixed cradle 3 of the vehicle.
Ainsi, contrairement à l'état de la technique, la biellette 9 n'est pas cintrée. Dans l'exemple représenté aux figures 2 et 3, les biellettes inférieures 10, 11 sont également rectilignes entre leurs deux points d'articulation E, C et H, L, respectivement.Thus, unlike the state of the art, the link 9 is not bent. In the example shown in Figures 2 and 3, the lower links 10, 11 are also straight between their two points of articulation E, C and H, L, respectively.
La biellette supérieure 9 est articulée au porte-fusée 8 en un point F qui est espacé de la face interne 7a du longeron arrière 7 du véhicule, vers le plan médian P du véhicule, dans une direction transversale à ce plan. Cette disposition permet d'éviter que la biellette 9 touche le longeron 7.The upper link 9 is articulated to the knuckle 8 at a point F which is spaced from the inner face 7a of the rear spar 7 of the vehicle towards the median plane P of the vehicle, in a direction transverse to this plane. This arrangement prevents the rod 9 touches the spar 7.
On voit également sur les figures 2 et 3 que le porte-fusée 8 supporte l'ensemble des biellettes 9, 10 et 1 1 et le ressort de suspension 12. Le porte- fusée 8 peut également supporter la butée de choc et l'amortisseur (non représentés). Dans l'exemple représenté, le porte-fusée 8 est réalisé d'une seule pièce en forme de cuve ouverte vers le haut dont le fond 13 supporte notamment le ressort 12. La paroi latérale 14 de cette cuve porte d'un côté la fusée 15 et le bord supérieur 16 de la paroi latérale de la cuve comporte à l'opposé de la fusée 15 le point d'articulation F de la biellette supérieure 9. Par ailleurs, le porte-fusée 8 est relié aux deux biellettes inférieures 10, 1 1 par des points d'articulation E, H, respectivement, qui sont situés près du fond 13 de la cuve et de la paroi 14 portant la fusée 15. La figure 3 montre d'autre part que le porte-fusée 8 supporte en outre un bras longitudinal rectiligne 17 dont l'extrémité 17a opposée au porte-fusée 8 est reliée à une partie fixe du véhicule.FIGS. 2 and 3 also show that the stub axle 8 supports all the links 9, 10 and 11 and the suspension spring 12. The stub axle 8 can also support the shock stop and the shock absorber (not shown) In the example shown, the knuckle 8 is made in one piece in the form of an upwardly open tank whose bottom 13 supports in particular the spring 12. The side wall 14 of this tank carries on one side the rocket 15 and the upper edge 16 of the side wall of the tank has opposite the rocket 15 the point of articulation F of the upper link 9. Moreover, the knuckle 8 is connected to the two lower links 10, 1 1 by points of articulation E, H, respectively, which are located near the bottom 13 of the tank and the wall 14 carrying the rocket 15. FIG. 3 shows, on the other hand, that the stub axle 8 also supports a rectilinear longitudinal arm 17 whose end 17a opposite the stub axle 8 is connected to a fixed part of the vehicle.
Grâce à l'invention, la conception de la bielle de carrossage 9 peut être, par exemple : une pièce unique emboutie en tôle d'acier recevant les articulations qui assurent la liaison d'un côté avec le porte-fusée, de l'autre à la caisse (via le berceau).Thanks to the invention, the design of the camber rod 9 may be, for example: a single piece stamped sheet steel receiving joints that provide the connection of one side with the knuckle, the other at the cash desk (via the cradle).
Un tube auquel est soudée à chaque extrémité une douille tubulaire recevant les articulations.A tube to which is welded at each end a tubular sleeve receiving the joints.
Le porte-fusée 8 est dans ce cas la seule pièce de fabrication complexe du train, puisque regroupant l'ensemble des fonctions support. Les trois bielles transversales 9, 10, 1 1 et le bras longitudinal 17 sont des pièces d'architecture très simple et donc faciles à fabriquer en grande série. Ainsi grâce à l'invention, la maîtrise des difficultés de conception et de réalisation des pièces du train arrière est simplifiée étant donné qu'elles sont concentrées sur une seule pièce le porte-fusée.The knuckle 8 is in this case the only piece of complex manufacturing of the train, since grouping all the support functions. The three transverse rods 9, 10, 1 1 and the longitudinal arm 17 are very simple architectural pieces and therefore easy to manufacture in large series. Thus, thanks to the invention, it is easier to master the difficulties of designing and producing the parts of the rear axle since they are concentrated on the single piece of the rocket carrier.
Un autre avantage de l'invention est de supprimer les effets de couple dus à l'appui du ressort sur une bielle inférieure transversale. Cet avantage permet également de simplifier la conception et la réalisation des biellettes transversales inférieures. Another advantage of the invention is to eliminate the effects of torque due to the support of the spring on a lower transverse rod. This advantage also makes it possible to simplify the design and construction of the lower transverse links.
