La fusée 12, qui reçoit le moyeu de roue 13, est solidaire d'un étrier 14 à sa partie de liaison 14a des branches 14b de celui-ci qui est sensiblement horizontal The spindle 12, which receives the wheel hub 13, is integral with a stirrup 14 at its connecting part 14a of the branches 14b thereof which is substantially horizontal
en position de repos du véhicule.in the vehicle rest position.
La fusée de roue 12 comporte une tête d'extrémité 12a faisant saillie du moyeu 13 de la roue 1 et fixée au corps 5a de l'amortisseur vertical 5 de façon que l'axe de la roue 1 soit perpendiculaire au corps 5a. Plus précisément, la tête 12a, de dimensions supérieures au corps de la fusée 12, est disposée derrière une paroi d'une pièce de support 15 qui est fixée, par exemple par soudage, au corps 5a de l'amortisseur 5 de façon à plaquer la tête 12a sur le corps 5a, c'est-à-dire que cette dernière est prise en sandwich entre la paroi de The wheel spindle 12 has an end head 12a projecting from the hub 13 of the wheel 1 and fixed to the body 5a of the vertical damper 5 so that the axis of the wheel 1 is perpendicular to the body 5a. More specifically, the head 12a, of dimensions greater than the body of the rocket 12, is disposed behind a wall of a support piece 15 which is fixed, for example by welding, to the body 5a of the damper 5 so as to press the head 12a on the body 5a, that is to say the latter is sandwiched between the wall of
la pièce de support 15 et le corps 5a. the support part 15 and the body 5a.
Le corps 5a de l'amortisseur 5 comprend, à sa partie inférieure, une partie formant languette verticale 5b qui est reliée à l'étrier 14 par un axe 16 constitué par un boulon, comme cela ressort de la figure 1, enserrant un manchon de caoutchouc 17 pour constituer une articulation élastique. La languette verticale 5b de l'amortisseur 5 passe entre les deux branches 14b de The body 5a of the shock absorber 5 comprises, at its lower part, a part forming a vertical tongue 5b which is connected to the stirrup 14 by a pin 16 constituted by a bolt, as can be seen in FIG. 1, enclosing a sleeve of rubber 17 to form an elastic joint. The vertical tongue 5b of the shock absorber 5 passes between the two branches 14b of
l'étrier 14.stirrup 14.
Les deux bras transversaux 2, 3 ont leurs extrémités opposées à la roue 1 articulées autour d'un axe commun 18 s'étendant longitudinalement par rapport au véhicule suivant l'axe XX' et fixé à la traverse d'essieu 10 par l'intermédiaire de deux manchons élastiques d'articulation en caoutchouc 19. Le bras avant 2 est de plus courte longueur que le bras arrière 3 et ces deux bras sont reliés respectivement aux deux branches 14b de l'étrier 14 par l'intermédiaire d'articulations élastiques 20, dont les axes sont The two transverse arms 2, 3 have their ends opposite to the wheel 1 articulated around a common axis 18 extending longitudinally with respect to the vehicle along the axis XX 'and fixed to the axle cross member 10 via of two elastic rubber articulation sleeves 19. The front arm 2 is shorter than the rear arm 3 and these two arms are connected respectively to the two branches 14b of the stirrup 14 by means of elastic articulations 20 , whose axes are
parallèles à l'axe XX' de pivotement des deux bras. parallel to the axis XX 'of pivoting of the two arms.
Le bras longitudinal 4 du train arrière est fixé à une extrémité à l'étrier 14 par l'intermédiaire d'une articulation élastique 21 dont l'axe est perpendiculaire The longitudinal arm 4 of the rear axle is fixed at one end to the stirrup 14 by means of an elastic articulation 21 whose axis is perpendicular
27884732788473
à l'axe XX' et à son extrémité opposée, par une articulation élastique 22, à un support 23 solidaire to the axis XX 'and at its opposite end, by an elastic articulation 22, to a support 23 integral
d'une traverse 24 de la caisse du véhicule. a cross member 24 of the vehicle body.
L'extrémité libre supérieure de la tige 5c de l'amortisseur 5 est reliée, par l'intermédiaire de cales élastiques 25 et d'un écrou 26, à un support approprié The upper free end of the rod 5c of the damper 5 is connected, by means of elastic shims 25 and a nut 26, to a suitable support
27 de la caisse du véhicule.27 of the vehicle body.
Le train arrière comprend en outre une barre anti- The rear axle further includes an anti-bar
dévers 28 reliée à la partie supérieure du corps 5a de l'amortisseur 5 par l'intermédiaire d'une biellette 29 et articulée à son extrémité opposée à la biellette 29 dans un palier 30 fixé à la traverse 24 de la caisse du véhicule. La cinématique de fonctionnement du train arrière ci-dessus décrit va être maintenant expliquée en liaison cant 28 connected to the upper part of the body 5a of the shock absorber 5 by means of a link 29 and articulated at its end opposite to the link 29 in a bearing 30 fixed to the cross member 24 of the vehicle body. The operating kinematics of the rear axle described above will now be explained in connection
avec les figures 4 et 5.with Figures 4 and 5.
Lorsque le véhicule se déplace dans un virage à droite, l'ensemble formant essieu arrière gauche représenté aux figures 1 à 3 entre dans une phase dite d'attaque et se déforme suivant la cinématique propre à cet essieu. Plus particulièrement, les deux bras de longueurs différentes 2, 3 permettent, par leurs articulations élastiques lors de la phase d'attaque, c'est-à-dire lorsque l'essieu tourne autour de l'axe XX' en se déplacant vers le haut comme représenté en figure 4 tout en gardant l'axe de roue ZZ1 dans un plan parallèle au sol, une rotation du plan de roue P vers l'intérieur du véhicule, déterminant ainsi un angle de pincement Q comme représenté en figure 5 pour permettre au véhicule d'adopter un comportement sous-vireur, When the vehicle is traveling in a right turn, the left rear axle assembly shown in FIGS. 1 to 3 enters a so-called attack phase and deforms according to the kinematics specific to this axle. More particularly, the two arms of different lengths 2, 3 allow, by their elastic articulations during the attack phase, that is to say when the axle rotates around the axis XX 'while moving towards the top as shown in FIG. 4 while keeping the wheel axis ZZ1 in a plane parallel to the ground, a rotation of the wheel plane P towards the interior of the vehicle, thus determining a pinch angle Q as shown in FIG. 5 to allow the vehicle to adopt understeer behavior,
favorisant ainsi la tenue de route du véhicule. thus promoting the handling of the vehicle.
La possibilité de conserver l'axe de roue ZZ1 dans un plan parallèle au sol lors de la déformation géométrique de l'essieu arrière est due à la liaison décrite ci-dessus de l'essieu de roue 12 au corps Sa de The possibility of keeping the wheel axle ZZ1 in a plane parallel to the ground during the geometric deformation of the rear axle is due to the connection described above of the wheel axle 12 to the body Sa of
l'amortisseur 5.shock absorber 5.

Les figures 4 et 5 permettent de constater que lors du déplacement vers le haut des deux bras 2, 3 à partir de leur position horizontale sensiblement dans un même plan, la valeur de l'arc de cercle AA1 (vu en projection sur un plan horizontal comme représenté en figure 5) du déplacement de l'extrémité du bras 3 de plus grande longueur est inférieure à la valeur de l'arc de cercle BB2 (vu en projection sur un plan horizontal comme représenté en figure 5) du déplacement de l'extrémité du bras de plus courte longueur 2, ce qui se traduit par la valeur d'angle O supérieure à la valeur d'angle y, correspondant ainsi au but recherché, à savoir l'obtention de l'angle de pincement Q de la roue 1. Si les bras 2, 3 étaient restés dans un même plan lors du déplacement de l'extrémité du bras 3 du point A au point Ai, l'arc de cercle AA1 aurait été supérieur à l'arc de cercle BB1, (toujours vu en projection sur un plan horizontal comme représenté en figure 5) ce qui se serait traduit par O < À, allant à l'encontre du but Figures 4 and 5 show that when moving up the two arms 2, 3 from their horizontal position substantially in the same plane, the value of the arc of circle AA1 (seen in projection on a horizontal plane as shown in FIG. 5) of the displacement of the end of the arm 3 of greater length is less than the value of the arc of a circle BB2 (seen in projection on a horizontal plane as represented in FIG. 5) of the displacement of the end of the arm of shorter length 2, which results in the value of angle O greater than the value of angle y, thus corresponding to the desired objective, namely to obtain the pinch angle Q of the wheel 1. If the arms 2, 3 had remained in the same plane when moving the end of the arm 3 from point A to point Ai, the arc of circle AA1 would have been greater than the arc of circle BB1, (always seen in projection on a horizontal plane as represented in figure 5) what s e would be translated as O <À, going against the goal
recherché.research.
Le train arrière de l'invention se distingue des trains arrière connus par le fait que le ressort de suspension 6 est séparé de l'amortisseur 5 et repose sur l'appui articulé 7 relié élastiquement aux deux bras de suspension 2, 3. Cette solution permet de dégager l'amortisseur 5, de le raccourcir et par conséquent de diminuer le volume occupé par le passage de roue à l'intérieur de l'habitacle du véhicule. Cette disposition permet en outre au ressort de suspension de bénéficier d'un appui "naturel" par la présence du brancard ou longeron 11 et, comme il s'agit d'une The rear axle of the invention is distinguished from the rear axle known by the fact that the suspension spring 6 is separated from the shock absorber 5 and rests on the articulated support 7 connected elastically to the two suspension arms 2, 3. This solution allows to release the shock absorber 5, to shorten it and consequently to decrease the volume occupied by the wheel arch inside the passenger compartment of the vehicle. This arrangement also allows the suspension spring to benefit from "natural" support by the presence of the stretcher or spar 11 and, as it is a
suspension à roues indépendantes, donc sans poutre- suspension with independent wheels, therefore without beam-
traverse, de libérer le passage du tube d'échappement crosspiece, to free the passage of the exhaust tube
dans l'axe longitudinal du véhicule. in the longitudinal axis of the vehicle.
