Description

La présente invention a pour objet un train
arrière de suspension de véhicule automobile du type
dans lequel chacune des deux roues opposées est portée
par un bras longitudinal, les extrémités avant de
chacun des bras étant reliées à une traverse
déformable élastiquement en torsion autour de son axe.
The subject of the present invention is a train
rear suspension of motor vehicle type
in which each of the two opposite wheels is carried
by a longitudinal arm, the front ends of
each of the arms being connected to a crosspiece
elastically deformable in torsion around its axis.

ltensemble formé par la traverse et les. deux bras
étant relié à la structure du véhicule par deux
paliers d'articulation agencés respectivement au
voisinage des deux extrémités transversales de la
traverse.
the assembly formed by the cross member and the. two arms
being connected to the vehicle structure by two
articulation bearings respectively arranged at
neighborhood of the two transverse ends of the
crosses.

Dans ce type de train arriere de suspension. In this type of rear suspension train.

notamment à bras tirés, le débattement vertical
simultané des deux roues arrière, connu sous le nom de
pompage, est rendu possible par rotation de 1 ensemble
en forme de U constitué par la traverse et les deux
bras autour des axes des deux paliers d'articulation.
especially with arms drawn, the vertical travel
simultaneous two rear wheels, known as
pumping, is made possible by rotation of 1 set
U-shaped formed by the cross and the two
arms around the axes of the two articulation bearings.

En cas de débattement vertical différent
pour les deux roues. c est-å-dire si le véhicule est
en dévers ou prend du roulis. la traverse subit une
torsion élastique autour de son axe d inertie.
In case of different vertical travel
for two wheels. that is, if the vehicle is
on a slope or roll. the crossbar undergoes a
elastic torsion around its axis of inertia.

Dans ce type de train arriére, on constate
cependant qu il n est pas toujours facile de réaliser
un compromis acceptable entre 1 élasticité en torsion
de la traverse qui est nécessaire pour les mouvements
de dévers ou de roulis et un encastrement très rigide
des bras qui est nécessaire pour assurer un bon 'comportement routier du véhicule. notamment si le
train est destiné à supporter des charges élevées.
In this type of rear train, we see
however it is not always easy to realize
an acceptable compromise between 1 torsional elasticity
of the crosspiece which is necessary for the movements
superelevation or roll and very rigid embedding
arms which is necessary to ensure good driving behavior of the vehicle. especially if the
train is intended to support high loads.

D'autre part ce type de train est difficilement
compatible avec son installation sur un véhicule
comportant une transmission de puissance aux roues
arriére. 1 arbre de transmission longitudinal
interférant avec la position de la traverse du train.
On the other hand, this type of train is hardly
compatible with its installation on a vehicle
having power transmission to the wheels
back. 1 longitudinal drive shaft
interfering with the position of the train sleeper.

Afin de remédier à ces inconvénients. In order to remedy these drawbacks.

l'invention propose-un train arrière du type mentionné plus haut caractérisé en ce que l'extrémite avant de l'un des bras est fixée rigidement et liée en rotation à une portion de la traverse, et en ce que l'extrémité avant de l'autre bras est fixée rigidement et liée en rotation à un manchon monté coaxial et tournant sur une autre portion opposée de la traverse et sur lequel est agencé l'un des deux paliers d'articulation.the invention proposes a rear axle of the type mentioned above, characterized in that the front end of one of the arms is rigidly fixed and linked in rotation to a portion of the cross-member, and in that the front end of the other arm is rigidly fixed and linked in rotation to a sleeve mounted coaxially and rotating on another opposite portion of the cross member and on which one of the two articulation bearings is arranged.

- Figure 1 is a top view of a rear suspension train according to the teachings of the invention;
- Figure 2 is an axial sectional view on an enlarged scale of the portion of the cross member on which the sleeve is mounted
- Figure 3 is a rear view of an alternative embodiment of the cross member for a vehicle having a longitudinal drive shaft; and

On a représenté aux figures 1 et 4 un train arrière de suspension de forme générale en U qui comprend une traverse 10 et deux bras longitudinaux 12 et 14 parallèles à l'axe longitudinal du véhicule non représenté. FIGS. 1 and 4 show a rear suspension train of general U-shape which comprises a cross member 10 and two longitudinal arms 12 and 14 parallel to the longitudinal axis of the vehicle, not shown.

Chacun des bras longitudinaux 12 et 14 supporte une fusée de roue arrière 16 et 18 respectivement sur chacune desquelles est montée une roue arrière 20, 22 respectivement. Each of the longitudinal arms 12 and 14 supports a rear wheel spindle 16 and 18 respectively on each of which is mounted a rear wheel 20, 22 respectively.

La fusée 16, 18 est montée au voisinage de l'extrémité arrière 24, 26 du bras longitudinal correspondant '12, 14. Un ressort hélicoidal de suspension 28, 30 respectivement est monté à l'extrêmité arrière 24, 26 et prend appui par son extrémité supérieure sur un élément de guidage 32. 34 fixé à la partie inférieure 36 de la caisse du véhicule. The rocket 16, 18 is mounted in the vicinity of the rear end 24, 26 of the corresponding longitudinal arm '12, 14. A helical suspension spring 28, 30 respectively is mounted at the rear end 24, 26 and is supported by its upper end on a guide element 32. 34 fixed to the lower part 36 of the vehicle body.

Chaque bras-de suspension 12,14 est équipé d'un amortisseur 38 40 respectiDement qui relie sensiblement le milieu du bras à la partie inférieure 36 de la caisse du véhicule. L'amortisseur est incline par rapport à la verticale et s'étend depuis le bras longitudinal vers l'avant du véhicule. Each suspension arm 12,14 is fitted with a shock absorber 38 40 respectively which substantially connects the middle of the arm to the lower part 36 of the vehicle body. The shock absorber is inclined relative to the vertical and extends from the longitudinal arm towards the front of the vehicle.

La traverse 10 est reliée à la partie inférieure 36 de la structure du véhicule par deux paliers d'articulation 42 et 44 qui, dans le mode de réalisation représenté, ont chacun leur axe parallèle à l'axe X-X de la traverse 10. The cross-member 10 is connected to the lower part 36 of the vehicle structure by two articulation bearings 42 and 44 which, in the embodiment shown, each have their axis parallel to the axis X-X of the cross-member 10.

La traverse 10 est réalisée en deux parties. The cross member 10 is made in two parts.

Une première portion de la traverse est constituée par un tube 46 de grande section circulaire sensiblement constante sur plus de la moitié de la longueur de la traverse, en partant de la gauche en considérant la figure 1, et qui se prolonge à partir d'un épaulement radial 48 par une autre portion opposée de diamètre réduit 50 jusqu'à l'autre extrémité libre oppose 52 de la traverse, à droite en considérant la figure 1. A first portion of the crosspiece is constituted by a tube 46 of large circular section substantially constant over more than half the length of the crosspiece, starting from the left considering FIG. 1, and which extends from a radial shoulder 48 by another opposite portion of reduced diameter 50 to the other opposite free end 52 of the cross member, to the right when considering FIG. 1.

L'extremité avant 54 du premier bras longitudinal de gauche 12 est soudée directement sur la surface extérieure de la première portion 46 de la traverse 10. Le bras longitudinal 12 est ainsi fixé rigidement et lié en rotation à cette première portion 46. The front end 54 of the first left longitudinal arm 12 is welded directly to the outer surface of the first portion 46 of the cross member 10. The longitudinal arm 12 is thus rigidly fixed and linked in rotation to this first portion 46.

Comme on peut le voir aux figures 1 et 2,- la seconde portion 50 de diamètre réduit reçoit un manchon tubulaire creux 56 qui est monté coaxial sur la portion de diamètre réduit 50 de la traverse 10 au moyen de deux bagues élastiques en élastomere 58 et 60.  As can be seen in FIGS. 1 and 2, the second portion 50 of reduced diameter receives a hollow tubular sleeve 56 which is mounted coaxially on the portion of reduced diameter 50 of the cross-member 10 by means of two elastic elastomer rings 58 and 60.

Chacune des bagues élastiques 58, 60 présente en section une forme tronconique qui va en s'évasant vers l'extrémité correspondante du manchon à laquelle elle est agencée, 62 et 64 respectivement. Each of the elastic rings 58, 60 has in section a frustoconical shape which widens towards the corresponding end of the sleeve to which it is arranged, 62 and 64 respectively.

La bague élastique de gauche 58 est en appui sur la surface extérieure d'un épaulement conique 66 de la traverse 10 qui relie la première portion 46 à la portion de diamètre réduit 50. The left elastic ring 58 is supported on the outer surface of a conical shoulder 66 of the cross member 10 which connects the first portion 46 to the reduced diameter portion 50.

La surface extérieure conique de la bague 58 coopère également avec la surface intérieure conique 68 d'angle correspondant de la première extrémité 62 du manchon 56 dont l'angle est sensiblement egal à celui de la surface 66. The conical outer surface of the ring 58 also cooperates with the conical inner surface 68 of corresponding angle of the first end 62 of the sleeve 56 whose angle is substantially equal to that of the surface 66.

De la même manière la bague élastique 60 coopère par sa surface conique extérieure avec la surface intérieure 70 de la seconde extrémité 64 du manchon. In the same way the elastic ring 60 cooperates by its external conical surface with the internal surface 70 of the second end 64 of the sleeve.

La bague élastique tronconique 60 prend appui par sa face intérieure sur une surface conique extérieure complémentaire 72 formée à la périphérie d'une douille en forme de talon 74 qui est enfilée sur l'extrémité libre 52 de la portion de diamètre réduit 50. The frustoconical elastic ring 60 is supported by its internal face on a complementary external conical surface 72 formed at the periphery of a heel-shaped bushing 74 which is threaded on the free end 52 of the reduced diameter portion 50.

La douille 74 est immobilisee en rotation par rapport à la portion 50 par exemple au moyen de cannelures axiales complémentaires 76 formees sur la portion 50 et dans l'alésage interne de la douille 74. The sleeve 74 is immobilized in rotation relative to the portion 50 for example by means of complementary axial grooves 76 formed on the portion 50 and in the internal bore of the sleeve 74.

La douille 74 est immobilisée axialement en direction de l'extrémité libre 52 par exemple au moyen d'un jonc d'arrêt 78 reçu dans une gorge radiale correspondante de la portion 50. The bushing 74 is immobilized axially in the direction of the free end 52, for example by means of a stop ring 78 received in a corresponding radial groove in the portion 50.

La douille 74 et le jonc 78 permettent de monter le manchon 56 sur la portion de diamètre réduit 50 en comprimant axialement les bagues élastiques tronconiques 58 et 60 entre leurs surfaces intérieure et extérieure associées. The bush 74 and the rod 78 allow the sleeve 56 to be mounted on the reduced diameter portion 50 by axially compressing the frustoconical elastic rings 58 and 60 between their associated interior and exterior surfaces.

Le jonc d'immobilisation axiale 78 peut à titre de variante non représentée être remplacé par un sertissage ou tout autre moyen approprié. The axial immobilization ring 78 may alternatively not shown be replaced by crimping or any other suitable means.

Comme on peut le constater à la figure 2. As can be seen in Figure 2.

l'extrémité 64 du manchon 56 se termine par une courte portion cylindrique 86 qui empêche l'échappement axial accidentel de la bague élastique 60. Des moyens équivalents peuvent étre agences à l'autre extrémité -62 du manchon 56.the end 64 of the sleeve 56 ends in a short cylindrical portion 86 which prevents accidental axial escape of the elastic ring 60. Equivalent means can be arranged at the other end -62 of the sleeve 56.

L'extrémité avant 80 du second bras longitudinal de droite t4 est soudée sur la surface périphérique extérieure du manchon 56 dont le diamètre est sensiblement egal à celui de la première portion 46 sur laquelle est soudée l'extrémité avant 54 du premier bras longitudinal 12. The front end 80 of the second right longitudinal arm t4 is welded to the outer peripheral surface of the sleeve 56 whose diameter is substantially equal to that of the first portion 46 onto which the front end 54 of the first longitudinal arm 12 is welded.

Le secohd bras longitudinal 14 est ainsi fixé rigidement et lié en rotation au manchon 56. The secohd longitudinal arm 14 is thus rigidly fixed and linked in rotation to the sleeve 56.

Le palier d'articulation de gauche 42 est fixé latéralement à la première portion 46 de la traverse tandis que le second palier d'articulation de droite 44 est fixé de la même façon au manchon 56. The left articulation bearing 42 is fixed laterally to the first portion 46 of the cross-member while the second right articulation bearing 44 is fixed in the same way to the sleeve 56.

Le train de suspension arrière comprend enfin deux renforts en équerre 82 et 84. Une extrémité du renfort de gauche 82 est soudée sur une face latérale du premier bras longitudinal 12 tandis que 'son autre extrémité est soudee sur la première portion 46 de la traverse,
D'une manière symétrique une extrémité du renfort de droite 84 est soudée sur le second bras longitudinal 14 tandis que son,extremite opposée est soudée sur la surface extérieure conique de gauche du manchon 56.
The rear suspension train finally comprises two square reinforcements 82 and 84. One end of the left reinforcement 82 is welded to a side face of the first longitudinal arm 12 while its other end is welded to the first portion 46 of the cross member,
Symmetrically, one end of the right reinforcement 84 is welded to the second longitudinal arm 14 while its opposite end is welded to the conical outer surface of the left of the sleeve 56.

Selon une technique connue, les axes des paliers d'articulation 42 et 44 peuvent ne pas entre parallèles à l'axe X-X de la traverse 10 mais inclinés par rapport à celui-ci afin de contrôler des phénomènes de "micro-braquage" du train de suspension en virage. According to a known technique, the axes of the articulation bearings 42 and 44 may not be parallel to the axis XX of the cross-member 10 but inclined relative to the latter in order to control phenomena of "micro-deflection" of the train suspension when cornering.

Comme on l'a illustré à la figure 3, le train de suspension selon l'invention qui vient d'être décrit est parfaitement compatible pour etre monté sur un véhicule comportant un arbre 88 de transmission de la puissance aux roues arrière, et par exemple sur un véhicule à quatre roues motrices. As illustrated in FIG. 3, the suspension train according to the invention which has just been described is perfectly compatible to be mounted on a vehicle comprising a shaft 88 for transmitting power to the rear wheels, and for example on a four-wheel drive vehicle.

Dans ce cas, il est en effet particulièrement aisé de déformer localement la portion de section continue 46 dans la zone centrale de la traverse pour y former un coude 90 qui passe au-dessus de l'arbre de transmission 88.  In this case, it is in fact particularly easy to locally deform the portion of continuous section 46 in the central region of the cross-member in order to form there an elbow 90 which passes over the transmission shaft 88.
