Abstract

The suspension unit for the wheels (R) is of the type where each wheel (R) is carried by means of a stub axle (1) and a hub carrier (2). The lower part of the carrier is linked to the structure (C) of the vehicle, partly by an arm (14), which is approximately transverse to a longitudinal torsion rod (4), and partly by an arm (8), which is approximately longitudinal and is an extension to the common transverse anti- roll bar (5). Each of the former transverse bars (14), is an extension, roughly at right angles to its associated longitudinal torsion bar. Both of the carrying arms (8,14) are, in effect, extensions from the free ends, roughly at right angles, and which are linked directly on to the hub carriers, by a bearing, which is approximately horizontal.

Description

La présente invention concerne une suspens ion pour train de roues de véhicule notamment automobile, du type comportant deux barres de torsion longitudinales et une barre anti-dévers. The present invention relates to a suspension ion for a train of wheels of a motor vehicle in particular, of the type comprising two longitudinal torsion bars and an anti-roll bar.

On connaît déjà une telle suspension dans laquelle chacune des deux roues est portée par l'intermédiaire d'une fusée par un porte-moyeu dont la partie inférieure est reliée à la structure du véhicule, d'une part, par un bras sensiblement transversal solidaire d'une barre de torsion longitudinale et, d'autre part, par un bras sensiblement longitudinal prolongeant une barre anti-dévers transversale. There is already known such a suspension in which each of the two wheels is carried by means of a rocket by a hub carrier whose lower part is connected to the structure of the vehicle, on the one hand, by a substantially transverse arm secured a longitudinal torsion bar and, on the other hand, by a substantially longitudinal arm extending a transverse anti-roll bar.

Toutefois, cette suspension connue a une structure complexe et comporte de nombreuses pièces augmentant le coût et le poids du véhicule. However, this known suspension has a complex structure and has many parts increasing the cost and the weight of the vehicle.

La présente invention a donc pour but d'éliminer les inconvénients précités et de proposer une nouvelle suspension pour train de roues de véhicule qui soit simple, légère et peu coûteuse à fabriquer. The present invention therefore aims to eliminate the aforementioned drawbacks and to propose a new suspension for a vehicle wheel train which is simple, light and inexpensive to manufacture.

A cet effet, l'invention a pour objet une suspension pour train de roues de véhicule, du type dans lequel chacune des deux roues est portée par l'intermédiaire d'une fusée par un porte-moyeu dont la partie inférieure est reliée à la structure du véhicule, d'une part, par un bras sensiblement transversal solidaire d'une barre de torsion longitudinale et, d'autre part, par un bras sensiblement longitudinal prolongeant une barre anti-dévers transversale commune, caractérisée en ce que chaque bras sensiblement transversal est un prolongement replié sensiblement à angle droit de la barre de torsion longitudinale associée. To this end, the subject of the invention is a suspension for a vehicle wheel train, of the type in which each of the two wheels is carried by a rocket by a hub carrier, the lower part of which is connected to the structure of the vehicle, on the one hand, by a substantially transverse arm secured to a longitudinal torsion bar and, on the other hand, by a substantially longitudinal arm extending a common transverse anti-roll bar, characterized in that each arm substantially transverse is a folded extension substantially at right angles to the associated longitudinal torsion bar.

Selon une autre caractéristique de l'invention, chaque bras se prolonge par une extrémité libre repliée sensiblement à angle droit qui s'articule directement sur le porte-moyeu associé dans un palier respectif sensiblement horizontal. According to another characteristic of the invention, each arm is extended by a free end folded substantially at a right angle which is articulated directly on the associated hub carrier in a respective substantially horizontal bearing.

Dans ce cas, on peut prévoir que le palier du portemoyeu dans lequel est reçue l'extrémité libre du bras longitudinal est parallèle à la fusée au droit d'un même plan vertical, les deux paliers de chaque porte-moyeu étant superposés et perpendiculaires entre eux. In this case, provision can be made for the bearing of the hub carrier in which the free end of the longitudinal arm is received is parallel to the spindle in line with the same vertical plane, the two bearings of each hub carrier being superimposed and perpendicular between them.

Selon une autre caractéristique de l'invention, la partie supérieure du porte-moyeu est reliée à la structure du véhicule par un amortisseur télescopique sensiblement vertical. According to another characteristic of the invention, the upper part of the hub carrier is connected to the structure of the vehicle by a substantially vertical telescopic damper.

On peut prévoir dans ce cas que l'articulation entre l'amortisseur et la partie supérieure du porte-moyeu est coaxiale à la fusée porte-roue et disposée juste au-dessus des deux paliers. In this case, provision can be made for the articulation between the shock absorber and the upper part of the hub carrier to be coaxial with the wheel carrier spindle and disposed just above the two bearings.

L'extrémité libre de chaque bras peut être monté dans le palier associé du porte-moyeu par l'intermédiaire d'au moins un manchon élastique filtrant les bruits de roulage et assurant une certaine souplesse de débattement de l'ensemble. The free end of each arm can be mounted in the associated bearing of the hub carrier by means of at least one elastic sleeve filtering the rolling noises and ensuring a certain flexibility of movement of the assembly.

De préférence, le porte-moyeu est symétrique par rapport à un plan vertical passant par l'axe de la fusée, de sorte que le même porte-moyeu peut être utilisé aussi bien pour la roue droite que la roue gauche. Preferably, the hub carrier is symmetrical with respect to a vertical plane passing through the axis of the spindle, so that the same hub carrier can be used for both the right wheel and the left wheel.

Selon encore une autre caractéristique, les deux barres de torsion longitudinales s'étendent parallèlement et côte à côte de manière à être prises en chape par un même palier double de fixation sur la caisse du véhicule. According to yet another characteristic, the two longitudinal torsion bars extend parallel and side by side so as to be taken in a yoke by the same double bearing for fixing to the body of the vehicle.

Les extrémités libres respectives des barres de torsion longitudinales peuvent être repliées sensiblement à angle droit, par exemple dans une direction horizontale et en sens opposés, de manière à être prises en chape par un palier double commun antirotatoire, par exemple en forme générale de
T, qui est également fixé à la caisse.The respective free ends of the longitudinal torsion bars can be folded substantially at a right angle, for example in a horizontal direction and in opposite directions, so as to be taken in clevis by a common double anti-rotation bearing, for example in general form of
T, which is also attached to the body.

La barre transversale anti-dévers est prise en chape, libre en rotation autour de son axe, dans des paliers de fixation sur le châssis. The anti-roll crossbar is taken in a yoke, free to rotate around its axis, in fixing bearings on the chassis.

On peut prévoir un manchon élastique filtrant interposé entre chaque barre et chaque palier de fixation sur le châssis. An elastic filter sleeve can be provided interposed between each bar and each bearing for fixing to the chassis.

L'invention sera mieux comprise et d'autres buts, détails, caractéristiques et avantages de celle-ci appraîtront plus clairement au cours de la description explicative qui va suivre d'un mode de réalisation particulier actuellement préféré de l'invention, donné uniquement à titre illustratif et non limitatif en référence aux dessins schématiques annexés, dans lesquels

Suivant l'exemple de réalisation représenté sur les dessins, la suspension de l'invention est montée entre des fusées 1 de support de roues R et le châssis C du véhicule. According to the embodiment shown in the drawings, the suspension of the invention is mounted between spindles 1 of wheel support R and the chassis C of the vehicle.

La suspension comporte un porte-moyeu 2 associé à chaque roue R par la fusée 1, un amortisseur vertical 3 reliant le châssis à la partie supérieure du porte-moyeu, deux barres de torsion longitudinales 4 et une barre anti dévers transversale 5 reliées à la partie inférieure du porte-moyeu 2. The suspension comprises a hub carrier 2 associated with each wheel R by the spindle 1, a vertical damper 3 connecting the chassis to the upper part of the hub carrier, two longitudinal torsion bars 4 and a transverse anti-roll bar 5 connected to the lower part of the hub holder 2.

La barre anti-dévers 5 est fixée au plancher du véhicule par deux paliers identiques 6 qui prennent en chape les extrémités opposées de la barre transversale anti-dévers 5. The anti-roll bar 5 is fixed to the vehicle floor by two identical bearings 6 which take the opposite ends of the anti-roll cross bar 5 into a yoke.

Les paliers 6 sont mieux représentés sur les figures 3 et 4 et sont constitués d'une chape en tôle emboutie ou en métal coulé sous pression, dans laquelle chape 6 est insérée la barre 5 avec interposition d'un manchon souple 7 en matière élastique telle que caoutchouc. The bearings 6 are better represented in FIGS. 3 and 4 and consist of a fork made of stamped sheet metal or of die-cast metal, in which the fork 6 is inserted the bar 5 with the interposition of a flexible sleeve 7 made of elastic material such than rubber.

La barre anti-dévers 5 se prolonge à ses deux extrémités opposées respectivement par un bras sensiblement longitudinal 8 coudé sensiblement à angle droit. L'extrémité libre 8a de chaque bras 8 est également repliée sensiblement à angle droit, vers l'extérieur et sensiblement parallèlement à la barre anti-dévers 5, laquelle extrémité libre repliée 8a est reçue dans un logement sensiblement horizontal et transversal 15 de la partie inférieure du porte-moyeu 2 avec interposition également d'un manchon souple 9. The anti-roll bar 5 is extended at its two opposite ends respectively by a substantially longitudinal arm 8 bent substantially at a right angle. The free end 8a of each arm 8 is also folded substantially at a right angle, towards the outside and substantially parallel to the anti-roll bar 5, which folded free end 8a is received in a substantially horizontal and transverse housing 15 of the part bottom of the hub holder 2 with also the interposition of a flexible sleeve 9.

On voit sur la figure 1 que la barre anti-dévers 5 et l'extrémité libre repliée 8a de chaque bras 8 peuvent pivoter autour de leur axe respectif, respectivement dans les paliers 6 et le logement 15, autorisant ainsi un débattement des bras 8, indiqué par des traits interrompus, dans un plan sensiblement vertical et longitudinal. It can be seen in FIG. 1 that the anti-roll bar 5 and the folded free end 8a of each arm 8 can pivot around their respective axis, respectively in the bearings 6 and the housing 15, thus allowing the arms 8 to travel, indicated by broken lines, in a substantially vertical and longitudinal plane.

Les bras 8 de la barre anti-devers 5 jouent donc également le rôle d'un bras tiré. The arms 8 of the anti-roll bar 5 therefore also play the role of a pulled arm.

Les deux barres de torsion longitudinales 4 sont prises en chape à leur extrémité arrière dans un palier double commun 10 pour la fixation sur le châssis C. De manière analogue aux paliers 6, un bloc souple 11 est intercalé entre le palier 10 et les barres de torsion 4 et entre les barres de torsion elles-mêmes. The two longitudinal torsion bars 4 are taken in clevis at their rear end in a common double bearing 10 for fixing to the chassis C. In a similar manner to the bearings 6, a flexible block 11 is interposed between the bearing 10 and the bars of torsion 4 and between the torsion bars themselves.

Les extrémités libres avant 4a des barres de torsion 4 sont repliées sensiblement à angle droit dans une direction horizontale et transversale et s'étendent en sens opposés.
Les extrémités 4a sont maintenues ensemble dans un palier commun antirotatoire 12 en forme générale de T avec interposition d'un manchon élastique 13 analogue au manchon 11. Les extrémités 4a des barres de torsion 4 étant empêchées de tourner par le palier 12, ces barres font office de ressort.The front free ends 4a of the torsion bars 4 are folded substantially at right angles in a horizontal and transverse direction and extend in opposite directions.
The ends 4a are held together in a common anti-rotation bearing 12 in the general shape of a T with the interposition of an elastic sleeve 13 similar to the sleeve 11. The ends 4a of the torsion bars 4 being prevented from rotating by the bearing 12, these bars make spring office.

Les extrémités arrière des barres de torsion 4 se prolongent respectivement par un bras sensiblement transversal 14 dont l'extrémité libre 14a est repliée également sensiblement à angle droit dans une direction longitudinale et horizontale pour venir se loger dans la partie inférieure du porte-moyeu 2. On remarque plus clairement sur les figures 9 et 10 que les extrémités 8a et 14a respectivement des bras 8 et 14 sont logées dans la partie inférieure du porte-moyeu 2 respectivement dans un trou traversant formant palier 15 et 16. The rear ends of the torsion bars 4 are extended respectively by a substantially transverse arm 14, the free end 14a of which is also folded back substantially at right angles in a longitudinal and horizontal direction so as to be housed in the lower part of the hub carrier 2. It can be seen more clearly in FIGS. 9 and 10 that the ends 8a and 14a respectively of the arms 8 and 14 are housed in the lower part of the hub carrier 2 respectively in a through hole forming a bearing 15 and 16.

Les trous traversants 15 et 16 sont superposés, sensiblement horizontaux et perpendiculaires entre eux, avec le palier 15 agencé au-dessus du palier 16. The through holes 15 and 16 are superimposed, substantially horizontal and perpendicular to each other, with the bearing 15 arranged above the bearing 16.

On voit également que les extrémités 8a et 14a sont reçues dans leur palier respectif 15 et 16 avec interposition de deux manchons souples 9 qui sont introduits à partir de chaque extrémité des trous traversants 15 et 16. It can also be seen that the ends 8a and 14a are received in their respective bearings 15 and 16 with the interposition of two flexible sleeves 9 which are introduced from each end of the through holes 15 and 16.

Chaque manchon souple 9 comporte à une extrémité dite externe une collerette circulaire radialement et extérieurement saillante 9a qui est destinée à venir en butée contre une face externe du porte-moyeu. On voit sur la figure 10 qu'un faible intervalle existe entre chaque manchon 9 à l'intérieur du trou traversant 15. Each flexible sleeve 9 comprises at a so-called external end a radially and externally projecting circular flange 9a which is intended to come into abutment against an external face of the hub carrier. It can be seen in FIG. 10 that a small gap exists between each sleeve 9 inside the through hole 15.

La portion terminale 8b et 14b de chaque extrémité 8a et 14a est filetée et destinée à dépasser de l'autre côté du trou traversant 15 et 16 respectivement pour pouvoir y visser un écrou 17 avec interposition d'une rondelle d'appui plate 18. The end portion 8b and 14b of each end 8a and 14a is threaded and intended to protrude from the other side of the through hole 15 and 16 respectively in order to be able to screw a nut 17 there with the interposition of a flat support washer 18.

On voit clairement sur la figure 10 que l'axe d'articulation 19 de l'amortisseur 3 sur le porte-moyeu 2 est aligné et coaxial à la fusée 1, avec un manchon élastique filtrant 20 qui est solidaire de l'amortisseur 3 et muni d'une armature interne tubulaire 21 emmanchée libre sur l'axe d'articulation 19. It is clearly seen in FIG. 10 that the articulation axis 19 of the damper 3 on the hub carrier 2 is aligned and coaxial with the spindle 1, with an elastic filter sleeve 20 which is integral with the damper 3 and provided with a tubular internal frame 21 fitted free on the hinge pin 19.

Le porte-moyeu 2 présente une forme générale en U en coupe verticale transversale telle que représentée sur la figure 10, avec l'extrémité inférieure de l'amortisseur 3 qui est prise en chape entre les branches du U en partie supérieure du porte-moyeu. Le porte-moyeu 2 est réalisé symétrique par rapport à un plan vertical passant par l'axe de la fusée 1 de manière à pouvoir être utilisé aussi bien pour la roue gauche que droite. The hub holder 2 has a general U shape in transverse vertical section as shown in FIG. 10, with the lower end of the damper 3 which is taken in a yoke between the branches of the U in the upper part of the hub holder . The hub carrier 2 is made symmetrical with respect to a vertical plane passing through the axis of the spindle 1 so that it can be used for both the left and right wheels.

Sur les dessins, les bras 8 et 14 ont été représentés sensiblement perpendiculaires à la barre anti-dévers et aux barres de torsion respectivement par souci de clarté, mais pour éviter qu'une inclinaison prononcée du porte-moyeu lors des grands débattements des bras ne nuise à la tenue de route du véhicule, les bras 8 et 14 pourront être réalisés avec une certaine inclinaison par rapport à cet angle droit. In the drawings, the arms 8 and 14 have been shown substantially perpendicular to the anti-roll bar and to the torsion bars respectively for the sake of clarity, but to avoid a pronounced inclination of the hub carrier during large arm deflections. affects the handling of the vehicle, the arms 8 and 14 can be made with a certain inclination relative to this right angle.

On voit également sur les figures 9 et 10 une rondelle 18 insérée sur les extrémités 8a et 14a et soudée dans une position proche du coude reliant chacune de ces extrémités au bras respectif 8 ou 14 pour venir en butée contre la collerette 9a d'un manchon 9. Also seen in Figures 9 and 10 a washer 18 inserted on the ends 8a and 14a and welded in a position close to the elbow connecting each of these ends to the respective arm 8 or 14 to abut against the flange 9a of a sleeve 9.

On obtient ainsi une barre anti-dévers 5 qui travaille en torsion avec ses bras longitudinaux 8 associés monobloc qui servent chacun de bras de support et de guidage d'un support de roue. De manière analogue, chaque barre longitudinale 4 travaille en torsion avec son bras transversal associé monobloc 14 qui sert également de bras de support et de guidage des roues. An anti-roll bar 5 is thus obtained which works in torsion with its longitudinal arms 8 associated in one piece which each serve as a support arm and for guiding a wheel support. Similarly, each longitudinal bar 4 works in torsion with its associated one-piece transverse arm 14 which also serves as a support arm and for guiding the wheels.

Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention.  Although the invention has been described in connection with a particular embodiment, it is obvious that it is in no way limited thereto and that it includes all the technical equivalents of the means described as well as their combinations if these are within the scope of the invention.
