Abstract

Rear suspension with an independent wheel (independent rear suspension) of the type consisting of two trailing arms connected transversely together by a V section 2, and by an anti-roll bar 25 joined at its middle to a torsion bar 23 secured to the body. The anti-roll bar is hollow and traversed by the torsion bar 23 which is concentric with it. Application to suspensions.

Description

SUSPENSION ARRIERE A ROUES INDEPENDANTES
La présente invention se rapporte à une suspension arrière à roues indépendantes du type de celle décrite dans le brevet français 2 550 495 de la demanderesse.
REAR SUSPENSION WITH INDEPENDENT WHEELS
The present invention relates to a rear suspension with independent wheels of the type described in French patent 2,550,495 of the applicant.

Cette suspension est caractérisée par une grande compacité et les propriétés mécaniques particulièrement avantageuses.This suspension is characterized by a great compactness and particularly advantageous mechanical properties.

La géométrie spécifique du train arrière qu' elle représente est constituée par la réunion transversale de deux bras tirés par
- un profil géométrique de guidage des roues
- une barre anti-dévers
- une barre de torsion, reliée à la précédente par une jumelle
située sensiblement en leur milieu.
The specific geometry of the rear axle that it represents consists of the transverse union of two arms pulled by
- a geometric profile for guiding the wheels
- an anti-roll bar
- a torsion bar, connected to the previous one by a binocular
located substantially in the middle.

la spécialisation de chacun de ces éléments permettant leur optimisation.the specialization of each of these elements allowing their optimization.

Outre le fait que l'ensemble cidessus peut être préassemblé et constitue ainsi un - module indépendant comportant toutes les fonctions de la suspension, la forme et l' orientation particulières du profil de guidage des roues perrnet d' induire des particularités de braquage déterminées en virage, accroissant ainsi la tenue de route du véhicule.In addition to the fact that the above assembly can be preassembled and thus constitutes an independent module comprising all the suspension functions, the particular shape and orientation of the guide profile of the perrnet wheels to induce specific turning characteristics determined when cornering. , thereby increasing the handling of the vehicle.

La présente invention a pour but de perfectionner la suspension cidessus, en augmentant encore sa compacité, sa légèreté, et en améliorant sa faisabilité.The present invention aims to improve the above suspension, further increasing its compactness, its lightness, and improving its feasibility.

Elle sera décrite à titre d'exemple non limitatif au regard des figures l à 3 ci-lointes, qui représentent respectivement - la figure l, une vue en perspective d'un détail de l'état antérieur de
la technique, montrant la partie du train sur laquelle porte la
modification - la figure 2, une vue en perspective partiellement éclatée du train selon l'invention - la figure 3, une coupe selon A A de la figure précédente.
It will be described by way of nonlimiting example with regard to Figures 1 to 3 below, which respectively represent - Figure 1, a perspective view of a detail of the previous state of
the technique, showing the part of the train on which the
modification - Figure 2, a partially exploded perspective view of the train according to the invention - Figure 3, a section along AA of the previous figure.

En référence à la figure 1, on voit que le demi-train arrière selon la technique antérieure qui est représenté comporte un bras de roue 1 relié à son homologue, d'une part par le profil géométrique du guidage 2- en V, et d' autre part par une barre anti-dévers 3 ; il est traversé par la barre de torsion 4 dont les extrémités sont reliées à la caisse, et le milieu à la barre 3 par une iumelle 5.With reference to FIG. 1, it can be seen that the rear undercarriage according to the prior art which is shown comprises a wheel arm 1 connected to its counterpart, on the one hand by the geometric profile of the 2- V-shaped guide, and d 'other hand by an anti-roll bar 3; it is crossed by the torsion bar 4, the ends of which are connected to the body, and the middle to the bar 3 by a wire 5.

A la figure 2, le train selon l'invention est constitué de deux bras tirés 20, reliés entre eux par le profil 2 et comportant des amortisseurs 21 ; il est fixé aux longerons 22 du véhicule resDectivement par ancrage de la barre de torsion 23 et par l'intermédiaire de tampons élastiques 24 entourant la barre anti-dévers 25.In Figure 2, the train according to the invention consists of two drawn arms 20, interconnected by the profile 2 and having dampers 21; it is fixed to the side members 22 of the vehicle respectively by anchoring the torsion bar 23 and by means of elastic buffers 24 surrounding the anti-roll bar 25.

La caractéristique remarquable de ce train, par rapport à 1' état antérieur de la technique cité en référence, réside dans le fait que les barres de torsion 23 et anti-dévers 24 sont concentriques et ont pour axe de rotation x' x, axe d' oscillation des roues 6. Elles sont réunies en leur milieu par un élément 26 qui peut être constitué par un ou plusieurs manchons, collés ou soudés.The remarkable characteristic of this train, compared to the prior art cited in reference, lies in the fact that the torsion bars 23 and anti-roll 24 are concentric and have the axis of rotation x 'x, axis d 'oscillation of the wheels 6. They are joined in the middle by an element 26 which may be constituted by one or more sleeves, glued or welded.

De cette disposition découlent les mêmes propriétés et avantages que ceux du dispositif faisant l' obJet du brevet français antérieurement cité 2 550 495, à savoir que lorsque les couples de torsions provenant des débattements des bras de roue 20 saturent les capacités de la barre de torsion 23, la barre anti-dévers 25 intervient, du fait de sa solidarisation à la barre 23 par l'élément 26.From this arrangement flow the same properties and advantages as those of the device forming the object of the previously cited French patent 2,550,495, namely that when the torques from the wheel arm deflections 20 saturate the capacities of the torsion bar 23, the anti-roll bar 25 intervenes, due to its connection to the bar 23 by the element 26.

Un avantage supplémentaire important découle toutefois de la présente disposition ; on voit en effet qu' au niveau de I' encombrement de l' ensemble constitué par le profil de guidage et les barres de torsion et anti-dévers, la représentation concentrique de ces dernières, bien visibles à la figure 3, occupe moins de place que le dispositif antérieur à lames parallèles de la figure 2 ; ceci permet par exemple d' augmenter sensiblement le volume du réservoir de carburant ou celui de échappement. An important additional advantage, however, follows from this provision; it can be seen that, at the level of the overall dimensions of the assembly formed by the guide profile and the torsion and anti-roll bars, the concentric representation of the latter, clearly visible in FIG. 3, occupies less space that the anterior device with parallel blades of FIG. 2; this allows, for example, to significantly increase the volume of the fuel tank or that of the exhaust.

On notera qu' à 1' avantage ci-dessus s'ajoute le gain de poids résultant du fait que 1' une au moins des barres est creuse et que, de surcrott, on peut la fabriquer, de manière connue en soi, en matière synthétique renforcée. It will be noted that to the above advantage is added the weight gain resulting from the fact that at least one of the bars is hollow and that, on top of it, it can be manufactured, in a manner known per se reinforced synthetic.
