Abstract

The present invention relates to a rear axle assembly for a motor vehicle. The rear axle assembly is characterised in that it comprises a Watt mechanism 3, the three bars 4, 10, 11 of which are located approximately in a horizontal plane located below the axes X-X' of the wheels of the vehicle and in that the axis of pivoting 5 of the central bar 4 is approximately vertical. The present invention finds an application for example for rear axle assemblies of the type with trailing arms.

Description

La présente invention concerne un train arrière pour véhicule automobile, notamment du type à bras tirés. The present invention relates to a rear axle for a motor vehicle, in particular of the type with drawn arms.

Elle vise également un véhicule automobile équipé d'un tel train arrière. It also relates to a motor vehicle equipped with such a rear axle.

Dans la demande de brevet français No.87 03 567 déposée aux noms des demanderesses, on a décrit un train arrière dans lequel les forces transversales exercées par le sol sur les roues arrière sont transmises à la caisse du véhicule par un mécanisme dit mécanisme de Watt" comprenant une barre ou biellette centrale montée en rotation en son centre sur un axe solidaire du véhicule et situé dans le plan de symétrie de celui-ci et articulée à ses extrémités à deux barres ou biellettes s'étendant transversalement de part et d'autre du plan de symétrie. In French patent application No. 87 03 567 filed in the names of the applicants, a rear axle has been described in which the transverse forces exerted by the ground on the rear wheels are transmitted to the vehicle body by a mechanism known as the Watt mechanism "comprising a central bar or rod mounted in rotation at its center on an axis integral with the vehicle and situated in the plane of symmetry thereof and articulated at its ends with two bars or rods extending transversely on either side of the plane of symmetry.

Ce mécanisme est suspendu à la caisse du véhicule par la barre centrale et les extrémités libres des barres transversales sont reliées aux supports des roues arrière par l'intermédiaire d'articulations élastiques ou de rotules. This mechanism is suspended from the vehicle body by the central bar and the free ends of the transverse bars are connected to the supports of the rear wheels by means of elastic joints or ball joints.

Ce mécanisme de Watt peut s'appliquer à un essieu rigide reliant les deux roues arrière ou être utilisé avec un essieu arrière à bras tirés et roues indépendantes ou un essieu arrière dit "à bras tirés et traverses déformables". This Watt mechanism can be applied to a rigid axle connecting the two rear wheels or can be used with a rear axle with pulled arms and independent wheels or a rear axle called "with pulled arms and deformable cross members".

Comme décrit dans la demande de brevet français susmentionnée, le mécanisme de Watt est disposé dans un plan vertical avec l'axe de la barre centrale horizontal et l'une des barres transversales nécessairement plus haute que l'autre. Ainsi, les efforts transversaux appliqués au véhicule se déplaçant par exemple dans un virage sont repris directement sur la caisse du véhicule par le mécanisme de Watt.  As described in the aforementioned French patent application, the Watt mechanism is arranged in a vertical plane with the axis of the horizontal central bar and one of the transverse bars necessarily higher than the other. Thus, the transverse forces applied to the vehicle moving for example in a turn are taken up directly on the vehicle body by the Watt mechanism.

Cependant, la disposition du mécanisme de Watt ci-dessus décrit est telle que celui-ci ne permet pas de transmettre efficacement à la caisse du véhicule les forces transversales et n'empêche pas la déformation des différents éléments composant la suspension. However, the arrangement of the Watt mechanism described above is such that it does not effectively transmit transverse forces to the vehicle body and does not prevent the various elements making up the suspension from being deformed.

La présente invention a pour but de palier les inconvénients ci-dessus en prévoyant un train arrière d'une structure transmettant efficacement les forces transversales à la caisse du véhicule, diminuant la déformation des éléments composants la suspension et donc préservant la géométrie de celle-ci et abaissant les fréquences de travail de ces éléments, d'où un allégement possible de suspension. The present invention aims to overcome the above drawbacks by providing a rear axle of a structure effectively transmitting the transverse forces to the vehicle body, reducing the deformation of the components of the suspension and therefore preserving the geometry thereof and lowering the working frequencies of these elements, hence a possible reduction in suspension.

Pour cela, le train arrière, du type comprenant deux supports de roues notamment à bras tirés, dont chaque extrémité arrière porte une roue et chaque extrémité avant est montée pivotante relativement à la structure du véhicu-le autour d'un axe transversal à celui-ci, un mécanisme à trois barres de Watt disposé entre les deux supports de façon que les deux barres approximativement transversales de celui-ci soient reliées articulées par leurs extrémités libres respectivement aux extrémités arrière des deux supports et que la barre centrale pivote autour d'un axe solidaire de la structure du véhicule et situé dans un plan de symétrie du'véhicule, est caractérisé en ce que les trois barres du mécanisme de Watt sont disposées approximativement dans un plan horizontal situé en dessous des axes des roues du véhicule et en ce que l'axe de pivotement de la barre centrale est approximativement vertical. For this, the rear axle, of the type comprising two wheel supports, in particular with pulled arms, each rear end of which carries a wheel and each front end is pivotally mounted relative to the structure of the vehicle around an axis transverse thereto. ci, a mechanism with three Watt bars arranged between the two supports so that the two approximately transverse bars of the latter are connected articulated by their free ends respectively to the rear ends of the two supports and that the central bar pivots around a axis integral with the structure of the vehicle and situated in a plane of symmetry of the vehicle, is characterized in that the three bars of the Watt mechanism are arranged approximately in a horizontal plane situated below the axes of the wheels of the vehicle and in that the pivot axis of the central bar is approximately vertical.

Le dispositif du mécanisme de Watt conforme à l'invention, permet de prendre la réaction des forces transversales dans chaque roue plus près du sol que celui du mécanisme décrit dans la demande de brevet français sumentionnée et donc d'abaisser le point de réaction, pour les deux roues. The device of the Watt mechanism according to the invention makes it possible to take the reaction of the transverse forces in each wheel closer to the ground than that of the mechanism described in the abovementioned French patent application and therefore to lower the reaction point, to the two wheels.

De préférence, le plan horizontal précité est proche de la garde au sol du véhicule et les points d'articulation des barres approximativement transversales précitées sont situés au voisinage d'un plan vertical passant par les axes des roues du véhicule. Preferably, the above-mentioned horizontal plane is close to the ground clearance of the vehicle and the points of articulation of the aforementioned approximately transverse bars are located in the vicinity of a vertical plane passing through the axes of the wheels of the vehicle.

Cette disposition permet de prendre la réaction transversale dans chaque roue le plus près possible du sol et donc d'abaisser au maximum le point de réaction à chacune des extrémités des barres approximativement transversales, les points de réactions étant de plus situés relativement au sol à des hauteurs égales. This arrangement makes it possible to take the transverse reaction in each wheel as close as possible to the ground and therefore to minimize the reaction point at each of the ends of the approximately transverse bars, the reaction points being moreover located relatively to the ground at equal heights.

L'invention sera mieux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci apparattront 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 2 est une vue suivant la flèche II de la figure 1
- la figure 3 est une vue en coupe suivant la ligne III-III de la figure 1 ; et
- la figure 4 est une vue en perspective de dessous suivant la flèche IV de la figure 1.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 embodiment of the invention, and in which
- Figure 1 is a perspective view of a rear axle of the drawn arms type according to the invention;
- Figure 2 is a view along arrow II of Figure 1
- Figure 3 is a sectional view along line III-III of Figure 1; and
- Figure 4 is a perspective view from below along arrow IV of Figure 1.

En se reportant aux figures, le train arrière pour véhicule automobile comprend, comme cela est déjà connu en soi, deux supports de roues 1 constitués dans le cas présent par deux bras tirés portant chacun à leur extrémité arrière la roue arrière R. Les deux bras 1 sont solidaires à leurs extrémités avant d'une traverse 2 (représentée partiellement) dont les deux extrémités sont fixées à la structure ou caisse du véhicule par l'intermédiaire respectivement de deux articulations relativement souples (non représentées) servant également d'axes de pivotement des bras par rapport à la structure du véhicule et disposés transversalement à celui-ci. Referring to the figures, the rear axle for a motor vehicle comprises, as is already known per se, two wheel supports 1 constituted in the present case by two pulled arms each carrying at their rear end the rear wheel R. The two arms 1 are secured at their front ends to a cross member 2 (partially shown), the two ends of which are fixed to the structure or body of the vehicle by respectively two relatively flexible joints (not shown) also serving as pivot axes arms relative to the structure of the vehicle and arranged transversely thereto.

Selon l'invention, un mécanisme 3 à trois barres de Watt est disposé entre les deux bras 1 approximativement dans un plan horizontal situé en dessous des axes X-X' des roues R. According to the invention, a mechanism 3 with three Watt bars is arranged between the two arms 1 approximately in a horizontal plane situated below the axes XX 'of the wheels R.

Plus précisément, le mécanisme 3 comprend une barre ou biellette centrale horizontale 4 montée pivotante autour d'un axe approximativement vertical 5 solidaire d'une traverse sensiblement en forme de V 6 en dessous de celle-ci, dont les deux extrémités opposées sont fixées rigidement sous deux longerons parallèles 7 et 8 de support du plancher 9 du véhicule. Les extrémités de la traverse 6 sont fixées aux longerons 7 et 8 par exemple par des vis de fixation (non représentées). Le mécanisme 3 comprend-de plus les deux autres barres approximativement transversales 10 et 11 ayant deux de leurs extrémités reliées de façon articulée respectivement aux deux extrémités opposées de la barre centrale 4 et leurs deux autres extrémités opposées reliées articulées respectivement aux extrémités arrière des deux bras 1 par des rotules 14 et 15. De préférence, la barre centrale 4 est formée de deux plaques parallèles longilignes 4a et 4b entre lesquelles sont fixés, au niveau de leurs extrémités, les axes d'articulation îOa et Ila des barres 10 et 11 et à travers lesquelles passe l'axe vertical de pivotement 5. More specifically, the mechanism 3 comprises a horizontal central bar or link 4 pivotally mounted about an approximately vertical axis 5 secured to a substantially V-shaped cross 6 below it, the two opposite ends of which are rigidly fixed under two parallel longitudinal members 7 and 8 for supporting the floor 9 of the vehicle. The ends of the cross-member 6 are fixed to the side members 7 and 8, for example by fixing screws (not shown). The mechanism 3 further comprises the two other approximately transverse bars 10 and 11 having two of their ends connected in an articulated manner respectively to the two opposite ends of the central bar 4 and their two other opposite ends connected hinged respectively to the rear ends of the two arms 1 by ball joints 14 and 15. Preferably, the central bar 4 is formed of two elongated parallel plates 4a and 4b between which are fixed, at their ends, the axes of articulation îOa and Ila of bars 10 and 11 and through which the vertical pivot axis 5 passes.

Avantageusement, le plan horizontal contenant les barres du mécanisme de Watt est situé le plus près possible du sol et est de préférence à une hauteur correspondant à la garde au sol du véhicule. Pour cela, les extrémités arrière des deux bras 1 comportent respectivement deux montants 16 et 17 s'étendant vers le sol et sur chacun desquels est reliée articulée l'extrémité correspondante des barres 10 et 11. Les points d'articulation 14 et 15 des barres 10 et 11 sont situés au voisinage d'un plan vertical passant par les axes X-X' des roues arrière R du véhicule. L'axe de pivotement 5 traversant la partie centrale de la barre 4 est suporté par une plaque métallique rigide en forme de
V 18 à fond plat parallèle à la partie inférieure plane du V formant la traverse 6. La plaque 18 forme, avec la partie inférieure plane de la traverse 6, une chape suspendant le mécanisme de Watt.La plaque 18 est rigidement fixée à la traverse 6 par ses deux bords latéraux opposés, par exemple par des vis de fixation ou par soudage. L'axe de pivotement 5, consitué par exemple par un boulon, traverse ainsi l'espace délimité entre les faces planes parallèles respectivement de la plaque 18 et de la traverse 6 en ayant sa tête en appui sur la face extérieure de la paroi formant fond de la plaque 18.et son extrémité opposée fixée, par exemple par vissage, dans la traverse 6. Les deux parois latérales inclinées de la plaque 18 comportent deux ouvertures 18a et 18b pour le passage respectivement des barres 10 et 11 en liaison articulée avec la barre centrale 4.Advantageously, the horizontal plane containing the bars of the Watt mechanism is located as close as possible to the ground and is preferably at a height corresponding to the ground clearance of the vehicle. For this, the rear ends of the two arms 1 respectively comprise two uprights 16 and 17 extending towards the ground and on each of which is articulated the corresponding end of the bars 10 and 11. The points of articulation 14 and 15 of the bars 10 and 11 are located in the vicinity of a vertical plane passing through the axes XX 'of the rear wheels R of the vehicle. The pivot axis 5 passing through the central part of the bar 4 is supported by a rigid metal plate in the form of
V 18 with a flat bottom parallel to the flat lower part of the V forming the cross member 6. The plate 18 forms, with the lower flat part of the cross member 6, a yoke suspending the Watt mechanism. The plate 18 is rigidly fixed to the cross member 6 by its two opposite lateral edges, for example by fixing screws or by welding. The pivot axis 5, constituted for example by a bolt, thus crosses the space delimited between the parallel flat faces of the plate 18 and of the cross member respectively, having its head resting on the external face of the wall forming the bottom of the plate 18.and its opposite end fixed, for example by screwing, in the cross-member 6. The two inclined lateral walls of the plate 18 have two openings 18a and 18b for the passage respectively of the bars 10 and 11 in articulated connection with the central bar 4.

L'agencement ainsi décrit du mécanisme de Watt présente donc une symétrie axiale autour de l'axe vertical passant par l'axe longitudinal de l'axe de pivotement 5. The arrangement thus described of the Watt mechanism therefore has an axial symmetry about the vertical axis passing through the longitudinal axis of the pivot axis 5.

La disposition du mécanisme de Watt conforme à l'invention permet de diminuer considérablement la déformation des différents éléments composant la suspension et donc d'assurer efficacement le maintien transversal du train arrière.  The arrangement of the Watt mechanism according to the invention makes it possible to considerably reduce the deformation of the various elements making up the suspension and therefore effectively ensure the transverse maintenance of the rear axle.
