Description

La présente invention concerne un essieu, notamment un essieu arrière multibras de véhicule automobile. The present invention relates to an axle, in particular a multi-link rear axle of a motor vehicle.

On a toujours cherché à réaliser des essieux de conception économique, faciles à monter et ayant un bon guidage de roue. We have always sought to produce axles of economical design, easy to assemble and having good wheel guidance.

La présente invention propose un essieu multibras réunissant les avantages ci-dessus. The present invention provides a multi-link axle combining the above advantages.

A cet effet, l'essieu conforme à l'invention, comprenant plusieurs bras transversaux dont une extrémité est liée au support de roue, est caractérisé en ce que l'autre extrémité des bras transversaux est liée au groupe motopropulseur du véhicule. To this end, the axle according to the invention, comprising several transverse arms, one end of which is linked to the wheel support, is characterized in that the other end of the transverse arms is linked to the powertrain of the vehicle.

De préférence, le moteur du groupe motopropulseur précité est un moteur non vibrant tel qu'un moteur électrique monté sur la caisse du véhicule par des liaisons de forte raideur. Preferably, the aforementioned powertrain engine is a non-vibrating engine such as an electric motor mounted on the vehicle body by very stiff links.

L'un des bras transversaux précités est constitué par le demi-arbre d'entraîriement de la roue. One of the aforementioned transverse arms is constituted by the drive half-shaft of the wheel.

De plus, l'un des bras transversaux précités sert à contrôler le pincement de la roue. In addition, one of the aforementioned transverse arms is used to control the pinching of the wheel.

Le bras de contrôle du pincement précité est situé en arrière du bras formant demi-arbre d'entrainement précité et sensiblement à la même hauteur que ce dernier. The aforementioned pinch control arm is located behind the aforementioned half-shaft forming arm and substantially at the same height as the latter.

Par ailleurs, l'un des bras transversaux porte le ressort de suspension etZou l'amortisseur correspondant. Furthermore, one of the transverse arms carries the suspension spring and or the corresponding shock absorber.

La roue est reliée à la caisse du véhicule par un bras tiré et trois bras transversaux articulés sur le groupe motopropulseur. The wheel is connected to the vehicle body by a pulled arm and three transverse arms articulated on the powertrain.

Le bras tiré précité est lié au support de roue par une articulation dont l'axe passe sensiblement par le centre de la zone de contact de la roue avec le sol. The aforementioned pulled arm is linked to the wheel support by an articulation whose axis passes substantially through the center of the zone of contact of the wheel with the ground.

L'essieu comprend de plus une barre anti-dévers montée dans deux paliers solidaires du groupe motopropulseur. The axle further includes an anti-roll bar mounted in two bearings integral with the powertrain.

L'articulation entre le bras porteur et le support de roue précités est plus souple que l'articulation entre le bras de contrôle de pincement et le support de roue. The articulation between the aforementioned support arm and the wheel support is more flexible than the articulation between the pinch control arm and the wheel support.

Avantageusement, le groupe motopropulseur est lié à la caisse du véhicule par des paliers dont l'un au moins comprend une masse élastique adhérisée d'une part à une douille solidaire du groupe motopropulseur et d'autre part à une douille solidaire de la caisse du véhicule, cette masse élastique comportant au moins une collerette apte à encaisser des efforts transversaux.  Advantageously, the powertrain is linked to the vehicle body by bearings, at least one of which comprises an elastic mass adhered on the one hand to a socket integral with the powertrain and on the other hand to a socket integral with the body of the vehicle, this elastic mass comprising at least one collar capable of absorbing transverse forces.

Le groupe motopropulseur est lié à la caisse du véhicule par un palier inférieur et deux paliers supérieurs situés dans le plan vertical contenant l'axe moteur et le centre de gravité du groupe motopropulseur. The powertrain is linked to the vehicle body by a lower bearing and two upper bearings located in the vertical plane containing the engine axis and the center of gravity of the powertrain.

L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels:
- la figure 1 représente en perspective un essieu arrière multibras de véhicule automobile conforme à l'invention; et
- la figure 2 est une vue représentant deux paliers de liaison du groupe motopropulseur du véhicule à la caisse de celui-ci.The invention will be better understood and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating a mode of the invention and in which:
- Figure 1 shows in perspective a multi-link rear axle of a motor vehicle according to the invention; and
- Figure 2 is a view showing two bearings connecting the powertrain of the vehicle to the body thereof.

En se reportant aux figures, l'essieu arrière de véhicule automobile est du type à plusieurs bras transversaux 1, 2, 3 dont une extrémité est liée au support 4 de roue 5. Referring to the figures, the rear axle of a motor vehicle is of the type with several transverse arms 1, 2, 3, one end of which is connected to the support 4 of the wheel 5.

Selon l'invention, l'extrémité opposée des bras transversaux 1, 2, 3 est liée de façon articulée au groupe motopropulseur 6 du véhicule, dont le moteur est monté sur la caisse ou châssis 7 du véhicule par des liaisons de forte raideur comme cela sera expliqué ultérieurement. Un moteur électrique comme mode de propulsion du véhicule est particulièrement adapté à l'essieu de l'invention. According to the invention, the opposite end of the transverse arms 1, 2, 3 is linked in an articulated manner to the powertrain 6 of the vehicle, the engine of which is mounted on the body or chassis 7 of the vehicle by very stiff connections like this. will be explained later. An electric motor as a mode of propulsion of the vehicle is particularly suitable for the axle of the invention.

Un tel moteur est très peu vibrant car son axe de rotation passe par le centre de gravité de l'ensemble, est facile à équilibrer et peut donc se fixer sur la caisse 7 d'une façon relativement rigide pour ne pas nuire au guidage de la roue 5.Such an engine has very little vibration because its axis of rotation passes through the center of gravity of the assembly, is easy to balance and can therefore be fixed to the body 7 in a relatively rigid manner so as not to interfere with guiding the wheel 5.

Le bras transversal 1 est constitué par le demi-arbre d'entraînement de la roue 5 et a ses deux extrémités reliées respectivement à l'arbre moteur 8 et à l'axe A de la roue 5, monté rotatif dans le support de roue 4, par deux articulations à la Cardan. The transverse arm 1 is constituted by the drive half-shaft of the wheel 5 and has its two ends connected respectively to the motor shaft 8 and to the axis A of the wheel 5, rotatably mounted in the wheel support 4 , by two Cardan joints.

Le bras transversal 2 sert à contrôler le pincement de la roue 5 et est situé en arrière du bras transversal de transmission 1 sensiblement à la même hauteur que ce dernier. Le bras 2 est lié de façon articulée au moteur du groupe motopropulseur 6 au point d'articulation 9 et au support de roue 4 au point d'articulation 10. The transverse arm 2 is used to control the pinching of the wheel 5 and is located behind the transverse transmission arm 1 at substantially the same height as the latter. The arm 2 is linked in an articulated manner to the engine of the powertrain 6 at the point of articulation 9 and to the wheel support 4 at the point of articulation 10.

Le bras transversal 3, disposé pratiquement sous le bras transversal de transmission 1, supporte le ressort de suspension 1 1 et/ou l'amortisseur 12 associés à la roue 5, le ressort 1 1 et l'amortisseur 12 s'appuyant sur une structure (non représentée) solidaire du châssis du véhicule. Le bras 3 est lié de façon articulée au moteur du groupe motopropulseur 6 et au support de roue 4 respectivement par les deux points d'articulation 13 et 14. The transverse arm 3, arranged practically under the transverse transmission arm 1, supports the suspension spring 1 1 and / or the damper 12 associated with the wheel 5, the spring 1 1 and the damper 12 resting on a structure (not shown) secured to the vehicle chassis. The arm 3 is linked in an articulated manner to the engine of the powertrain 6 and to the wheel support 4 respectively by the two articulation points 13 and 14.

Les liaisons des bras 1, 2, 3 au support de roue 4 sont pratiquement situées dans un plan parallèle au plan vertical contenant l'axe longitudinal de la caisse du véhicule. Le support de roue 4, et donc la roue 5, est relié à la caisse 7 du véhicule non seulement par l'intermédiaire des bras 1, 2, 3, mais également par un bras tiré 15 arrêtant le support 4 par rapport à la caisse du véhicule. Le bras tiré 15 est fixé de façon articulée à la caisse 7 du véhicule au point d'articulation 16 et est lié au support de roue 4 par une articulation 17 dont l'axe passe sensiblement par le centre C de la zone de contact de la roue 5 avec le sol
S. Le bras tiré 15 reprend tous les efforts horizontaux et le couple de freinage.The connections of the arms 1, 2, 3 to the wheel support 4 are practically situated in a plane parallel to the vertical plane containing the longitudinal axis of the vehicle body. The wheel support 4, and therefore the wheel 5, is connected to the body 7 of the vehicle not only by means of the arms 1, 2, 3, but also by a pulled arm 15 stopping the support 4 relative to the body of the vehicle. The pulled arm 15 is articulatedly fixed to the body of the vehicle 7 at the articulation point 16 and is linked to the wheel support 4 by an articulation 17 whose axis passes substantially through the center C of the contact zone of the wheel 5 with soil
S. The pulled arm 15 takes up all the horizontal forces and the braking torque.

L'essieu peut comporter, si nécessaire, une barre anti-dévers 18 montée dans deux paliers 19, 20 solidaires du groupe motopropulseur 6 et reliée de façon articulée au support de roue 4.  The axle may include, if necessary, an anti-roll bar 18 mounted in two bearings 19, 20 integral with the powertrain 6 and hingedly connected to the wheel support 4.

S'il est nécessaire de donner un effet autobraqueur à l'essieu, l'articulation entre le bras porteur 3 et le support de roue 4 est agencée de façon à être plus souple que l'articulation entre le bras de contrôle de pincement 2 et le support de roue 4. If it is necessary to give a self-tracking effect to the axle, the articulation between the support arm 3 and the wheel support 4 is arranged so as to be more flexible than the articulation between the pinch control arm 2 and the wheel support 4.

Comme représenté en particulier sur la figure 2, le groupe motopropulseur 6 est lié à la caisse 7 du véhicule par deux paliers supérieurs 21, 22 et un palier inférieur 23 reprenant le couple moteur, solidaires du groupe motopropulseur 6. Les deux paliers supérieurs 21, 22 sont situés dans le plan vertical contenant l'axe moteur et le centre de gravité du groupe motopropulseur 6. Chaque palier supérieur 21, 22 comprend une masse élastique 24 ou silentbloc adhérisée dans un manchon 25 solidaire du groupe motopropulseur 6 et à une douille 26 solidaire de la caisse 7 du véhicule en étant fixée dans une partie formant étrier de fixation 27 par un boulon 28. Chaque masse élastique 24 comporte au moins une collerette 29 apte à encaisser des efforts transversaux. En effet, un effort axial de sens Fl, venant de la roue 5, est encaissé par la collerette 29 formant butée de la masse élastique 24 appartenant au palier 22. Si l'effort axial F1 change de sens, c'est la collerette 29 de la masse élastique 24 appartenant au palier 21 qui encaisse cet effort. As shown in particular in FIG. 2, the powertrain 6 is linked to the body 7 of the vehicle by two upper bearings 21, 22 and a lower bearing 23 incorporating the engine torque, integral with the powertrain 6. The two upper bearings 21, 22 are located in the vertical plane containing the engine axis and the center of gravity of the powertrain 6. Each upper bearing 21, 22 comprises an elastic mass 24 or silentbloc adhered in a sleeve 25 secured to the powertrain 6 and to a socket 26 integral with the body of the vehicle 7 by being fixed in a portion forming a fixing bracket 27 by a bolt 28. Each elastic mass 24 comprises at least one flange 29 capable of absorbing transverse forces. Indeed, an axial force of direction F1, coming from the wheel 5, is collected by the flange 29 forming a stop for the elastic mass 24 belonging to the bearing 22. If the axial force F1 changes direction, it is the flange 29 of the elastic mass 24 belonging to the bearing 21 which collects this effort.

En cas d'efforts radiaux F2 parallèles au plan de l'axe longitudinal de la caisse 7 du véhicule, les parties centrales 30 et 31 des masses élastiques 24 prennent une légère flèche acceptable par les bras transversaux 2 et 3 qui agissent alors comme un parallélogramme.  In the event of radial forces F2 parallel to the plane of the longitudinal axis of the vehicle body 7, the central parts 30 and 31 of the elastic masses 24 take a slight deflection acceptable by the transverse arms 2 and 3 which then act as a parallelogram .

Le palier inférieur 23, constitué de deux masses élastiques du même type que celles des paliers supérieurs 21 et 22, partage les efforts F 1 et F2 cidessus avec les paliers 21 et 22.  The lower bearing 23, made up of two elastic masses of the same type as those of the upper bearings 21 and 22, shares the forces F 1 and F2 above with the bearings 21 and 22.
