Description

La présente invention concerne une suspension pour un train de roues arrière indépendantes de véhicule automobile. The present invention relates to a suspension for a train of independent rear wheels of a motor vehicle.

L'invention concerne plus particulièrement une suspension du type de celle décrite et représentée dans le document FR-A-2.393.690 dans laquelle chaque roue est portée à rotation à ltextrémité arrière d'un bras longitudinal tiré dont l'extrémité avant est montée à rotation par rapport à la caisse du véhicule autour d'un axe transversal sensiblement parallèle à l'axe de la fusée de la roue. The invention relates more particularly to a suspension of the type described and shown in document FR-A-2,393,690 in which each wheel is rotatably carried at the rear end of a drawn longitudinal arm whose front end is mounted at rotation relative to the body of the vehicle about a transverse axis substantially parallel to the axis of the wheel spindle.

Selon la conception décrite dans ce document, la roue est montée à rotation par sa fusée à l'extrémité arrière du bras tiré selon un montage qui ne permet aucun déplacement relatif de la roue par rapport au bras tiré. According to the design described in this document, the wheel is rotatably mounted by its spindle at the rear end of the pulled arm in an arrangement which does not allow any relative movement of the wheel relative to the pulled arm.

La suspension est complétée, pour chaque roue, par un ensemble comportant une barre de torsion et un amortisseur. The suspension is completed, for each wheel, by an assembly comprising a torsion bar and a shock absorber.

La présente invention a pour but de proposer un perfectionnement d'une suspension de ce type qui permet d'obtenir un effet d'effacement longitudinal de la roue lors d'un passage de corde, -et ceci en prévoyant des moyens d'absorption d'énergie qui permettent d'emmagasi- ner lténergie lors du passage de corde sans que des chocs ou des vibrations soient transmis à la caisse du véhicu- le. The object of the present invention is to propose an improvement of a suspension of this type which makes it possible to obtain a longitudinal erasure effect of the wheel during a passage of the rope, and this by providing means for absorbing 'energy which allows energy to be stored during rope passage without shock or vibration being transmitted to the vehicle body.

Dans ce but, l'invention propose une suspension du type mentionnée précédemment, caractérisée en ce que chaque fusée de roue est portée par un porte-fusée relié au bras de suspension en deux premiers points, agencés de part et d'autre de l'axe de la fusée dans un plan vertical décalé vers l'arrière par rapport à l'axe de la fusée, au moyen de deux premières articulations élastiques à axes horizontaux et sensiblement parallèles à l'axe longitudinal du véhicule, et en un troisième point, agencé entre l'axe de la fusée et l'axe d'articulation de ltextrémité avant du bras, par une troisième articulation élastique dont l'axe est sensiblement horizontal et forme un angle aigu par rapport au plan vertical passant par les axes des deux premières articulations. To this end, the invention provides a suspension of the type mentioned above, characterized in that each wheel stub is carried by a stub axle connected to the suspension arm at two first points, arranged on either side of the axis of the rocket in a vertical plane offset towards the rear with respect to the axis of the rocket, by means of two first elastic articulations with horizontal axes and substantially parallel to the longitudinal axis of the vehicle, and at a third point, arranged between the axis of the rocket and the axis of articulation of the front end of the arm, by a third elastic articulation whose axis is substantially horizontal and forms an acute angle relative to the vertical plane passing through the axes of the first two joints.

Selon d'autres caractéristiques de l'invention :
- chacune des articulations élastiques comporte une tige montée dans un manchon déformable élastiquement de manière à permettre des déplacements relatifs selon une direction radiale par rapport à l'axe de la tige ;
- chacune des deux premières articulations élastiques présente une raideur axiale faible et une raideur radiale élevée ;
- le point dtintersection entre le plan vertical passant par les deux premiers points de liaison et perpendiculaire aux axes des deux premières articulations élastiques avec le plan vertical passant par le troisième point de liaison et perpendiculaire à l'axe de la troisième articulation élastique est situé à ltextérieur par rapport au plan médian de la roue associée.
According to other characteristics of the invention:
- Each of the elastic joints comprises a rod mounted in an elastically deformable sleeve so as to allow relative movements in a radial direction relative to the axis of the rod;
- Each of the first two elastic joints has a low axial stiffness and a high radial stiffness;
- the point of intersection between the vertical plane passing through the first two connecting points and perpendicular to the axes of the first two elastic joints with the vertical plane passing through the third connecting point and perpendicular to the axis of the third elastic joint is located at the interior relative to the median plane of the associated wheel.

D'autres caractéristiques et avantages de l'inven- tion apparaîtront à la lecture de la description détail lée qui va suivre pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels :
- La figure 1 est une vue de dessus, avec des sections partielles, de la suspension de la roue arrière de gauche d'un véhicule réalisée conformément aux enseignements de l'invention ; et
- la figure 2 est une vue latérale en élévation illustrant notamment le porte-fusée et une partie du bras de suspension.
Other characteristics and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:
- Figure 1 is a top view, with partial sections, of the suspension of the left rear wheel of a vehicle produced in accordance with the teachings of the invention; and
- Figure 2 is a side elevational view illustrating in particular the stub axle and part of the suspension arm.

On a représenté aux figures 1 et 2 une roue 10 dont la suspension par rapport à la structure de la caisse du véhicule est assurée au moyen d'un bras longitudinal tiré 12 dont l'extrémité avant, en considérant le sens d'avancement en marche avant du véhicule, comporte une articulation élastique 14 qui permet l'articulation à rotation du bras longitudinal tiré 12 autour d'un axe transversal d'articulation Al qui est sensiblement perpendiculaire à l'axe longitudinal médian du véhicule (non représenté). There is shown in Figures 1 and 2 a wheel 10 whose suspension relative to the structure of the vehicle body is provided by means of a longitudinal arm pulled 12 whose front end, considering the direction of advance in motion front of the vehicle, comprises an elastic articulation 14 which allows the articulation to rotate of the longitudinal arm 12 pulled around a transverse axis of articulation A1 which is substantially perpendicular to the median longitudinal axis of the vehicle (not shown).

L'extrémité arrière 16 du bras 12 est relié à un amortisseur 18 et elle supporte à rotation la roue 10, autour d'un axe transversal A2 de rotation qui est sensiblement parallèle à l'axe transversal Al, par l'intermédiaire d'un porte-fusée 20. The rear end 16 of the arm 12 is connected to a damper 18 and it rotatably supports the wheel 10, around a transverse axis A2 of rotation which is substantially parallel to the transverse axis Al, by means of a stub axle 20.

Le porte-fusée 20 est une pièce de fonderie à trois bras dont la partie centrale en forme de moyeu 22 reçoit une fusée 24 pour le montage à rotation, selon une technique connue, de la roue 10 autour de l'axe A2. The knuckle carrier 20 is a three-arm foundry piece whose central hub-shaped part 22 receives a knuckle 24 for the rotational mounting, according to a known technique, of the wheel 10 around the axis A2.

Le porte-moyeu 20 comporte deux bras verticaux 26 et 28 qui s'étendent chacun dans une direction opposée, respectivement vers le haut et vers le bas, et dont chacun présente une extrémité libre 30, 32 en forme de manchon qui reçoit une douille en matériau élastomère 34 (voir figure 1 pour la représentation détaillée de l'extrémité 30 du bras 26) dont chacune reçoit le corps lisse en forme de tige 36, 38 d'une vis 40, 42 dont l'extrémité filetée 44 est vissée dans une portion en vis-à-vis 46, 48 respectivement de l'extrémité arrière 16 du bras 12. The hub carrier 20 comprises two vertical arms 26 and 28 which each extend in an opposite direction, respectively upwards and downwards, and each of which has a free end 30, 32 in the form of a sleeve which receives a socket in elastomeric material 34 (see FIG. 1 for the detailed representation of the end 30 of the arm 26) each of which receives the smooth rod-shaped body 36, 38 with a screw 40, 42 whose threaded end 44 is screwed into a facing portion 46, 48 respectively of the rear end 16 of the arm 12.

Le porte-fusée 20 est ainsi relié au bras 12 par l'intermédiaire de deux premières articulations élastiques 50 et 52 dont les axes A3 et A4 sont parallèles et sensiblement horizontaux et sont situés dans un même plan vertical perpendiculaire à l'axe A2 de la fusée 24. The stub axle 20 is thus connected to the arm 12 by means of two first elastic articulations 50 and 52 whose axes A3 and A4 are parallel and substantially horizontal and are situated in the same vertical plane perpendicular to the axis A2 of the rocket 24.

Les articulations élastiques 50 et 52 autorisent des déplacements radiaux des tiges 36, 38 par rapport aux extrémités 30 et 32, ces deux articulations élastiques définissant ainsi en leurs centres deux points de liaison et d'articulation P1 et P2 du porte-fusée 20 sur le bras 12. The elastic joints 50 and 52 allow radial movements of the rods 36, 38 relative to the ends 30 and 32, these two elastic joints thus defining at their centers two points of connection and articulation P1 and P2 of the stub axle 20 on the arm 12.

Comme on peut le voir sur la figure 2, les deux points de liaisons P1 et P2 sont agencés dans un plan vertical PV1 perpendiculaire aux axes A3 et A4 qui est décalé vers l'arrière par rapport à l'axe A2 de la fusée. As can be seen in FIG. 2, the two connection points P1 and P2 are arranged in a vertical plane PV1 perpendicular to the axes A3 and A4 which is offset rearward relative to the axis A2 of the rocket.

Les douilles en matériau élastomère 34 des articulations élastiques 50 et 52 sont choisies de manière que ces articulations présentent une raideur axiale faible (3 mm/100 daN) et une raideur radiale élevée (1000 daN/mm). The sockets made of elastomeric material 34 of the elastic joints 50 and 52 are chosen so that these joints have a low axial stiffness (3 mm / 100 daN) and a high radial stiffness (1000 daN / mm).

La raideur axiale faible permet d'absorber les efforts de percussions lorsque la roue rencontre un obstacle tandis que la raideur radiale élevée confère une très grande raideur de carrossage à la suspension. The low axial stiffness makes it possible to absorb the impact forces when the wheel encounters an obstacle while the high radial stiffness gives the suspension a very high camber stiffness.

Le porte-fusée 20 comporte un troisième bras 54 qui s'étend sensiblement horizontalement vers l'avant depuis l'axe A2 et qui comporte une extrémité 56 en forme de manchon qui reçoit une douille en matériau élastomère 58 qui est traversé par le corps lisse en forme de tige 60 d'une vis 62 dont l'extrémité filetée 64 est vissée dans une portion en vis-à-vis 66 de la partie centrale du bras longitudinal tiré 12. The knuckle carrier 20 comprises a third arm 54 which extends substantially horizontally forward from the axis A2 and which comprises an end 56 in the form of a sleeve which receives a sleeve made of elastomeric material 58 which is crossed by the smooth body in the form of a rod 60 with a screw 62, the threaded end 64 of which is screwed into a portion facing the 66 of the central part of the drawn longitudinal arm 12.

Le porte-fusée 20 est ainsi relié au bras de suspension par une troisième articulation élastique 68 dont l'axe A5 s'étend dans un plan sensiblement horizontal et forme (comme on peut le voir sur la figure 1), un angle aigu par rapport au plan vertical PV1. The stub axle 20 is thus connected to the suspension arm by a third elastic articulation 68 whose axis A5 extends in a substantially horizontal plane and forms (as can be seen in FIG. 1), an acute angle with respect to in the vertical plane PV1.

Le centre P3 de la troisième articulation élastique 68 définit un troisième point de liaison et d'articulation du porte-fusée 20 par rapport au bras de suspension 12.  The center P3 of the third elastic articulation 68 defines a third point of connection and articulation of the stub axle 20 relative to the suspension arm 12.

Comme on peut le voir sur la figure 1, l'intersection du plan vertical PV2 passant par le point P3 et perpendiculaire à l'axe A5 de la troisième articulation 68 avec le plan vertical PV1 définit un point CIR qui est le centre instantané de rotation du porte-fusée par rapport au bras 12 qui est situé à l'extérieur par rapport au plan vertical médian PV3 de la roue 10. As can be seen in FIG. 1, the intersection of the vertical plane PV2 passing through the point P3 and perpendicular to the axis A5 of the third articulation 68 with the vertical plane PV1 defines a point CIR which is the instantaneous center of rotation of the stub axle with respect to the arm 12 which is located outside with respect to the median vertical plane PV3 of the wheel 10.

L'articulation élastique 68 dont l'axe A5 est orienté par rapport au plan PV1 en association avec le bras 54 du porte-fusée 20 est assimilable à une biellette de direction (comme dans le cas d'une suspension de roue avant directrice) qui contrôle le plan de la roue en parallélisme et en variation du pincement. The elastic articulation 68, the axis A5 of which is oriented relative to the plane PV1 in association with the arm 54 of the stub axle carrier 20 can be likened to a steering rod (as in the case of a front steering wheel suspension) which controls the plane of the wheel in parallelism and in variation of the pinch.

L'ensemble constitué par la roue 10, ses moyens de montage, le porte-fusée 20 et le frein 72 est filtré en vibration par rapport au bras 12. The assembly constituted by the wheel 10, its mounting means, the stub axle 20 and the brake 72 is filtered in vibration with respect to the arm 12.

L'agencement selon l'invention permet d'obtenir un bon filtrage des vibrations sans nuire aux qualités de guidage du train arrière, ni à l'efficacité de l'amortissement.  The arrangement according to the invention makes it possible to obtain good filtering of the vibrations without harming the guiding qualities of the rear axle, nor the efficiency of the damping.
