Abstract

The subject of the present invention is a motor vehicle suspension comprising an elastic strip 1 or 1a which is fixed elastically at at least one point, onto the body 2 of the vehicle and one end of which bears on a wheel support arm 5 articulated onto the body 2 whilst its other end bears either on the body, or on a second wheel support arm which is symmetric with the first with respect to the longitudinal axis 12 of the vehicle. According to the invention, the strip 1 or 1a is fixed elastically to the body 2 by means of at least one articulation support 3 secured to the strip, whilst each end of the strip rests on the arm 5 or the body 2 by means of a rubber shoe 4 or 13.

Description

La présente invention concerne une suspension de véhicule automobile comprenant une lame élastique qui est fixée élastiquement en au moins un point sur la caisse du véhicule et dont une extrémité est en appui sur un bras de support de roue articule sur la caisse alors que son autre extrémité est en appui soit sur la caisse, soit sur un second bras de support de roue symétrique du premier par rapport à l'axe longitudinal du véhicule.The present invention relates to a suspension of a motor vehicle comprising an elastic blade which is fixed elastically at at least one point on the body of the vehicle and one end of which is supported on a wheel support arm articulated on the body while its other end is supported either on the body or on a second wheel support arm symmetrical with the first with respect to the longitudinal axis of the vehicle.

Si la lame est orthogonale à l'axe d'articulation du bras, lors de l'utilisation du véhicule, chaque point de l'extrémité de la lame en appui sur ledit bras de support de roue décrit approximativement un arc de cercle centré sur un axe parallele å l'axe d'articulation du bras de support de roue. Si les deux axes sont confondus ou situés le plus près possible l'un de l'autre, il n'y a quasiment pas de déplacement relatif de la lame et du bras pendant les débattements de la suspension.If the blade is orthogonal to the axis of articulation of the arm, when using the vehicle, each point of the end of the blade in abutment on said wheel support arm roughly describes an arc of circle centered on a axis parallel to the hinge axis of the wheel support arm. If the two axes are merged or located as close as possible to each other, there is almost no relative movement of the blade and the arm during the deflections of the suspension.

La présente invention a pour objet une suspension du type indiqué ci-dessus et dans laquelle cette condition de confidence ou de proxilité des axes est facilement remplie. Une telle disposition permet de n4 savoir que des éléments sans articulation mécanique entre lame et caisse d'une part et entre lame et bras d'autre part.The subject of the present invention is a suspension of the type indicated above and in which this condition of confidence or proximity to the axes is easily fulfilled. Such an arrangement allows n4 to know that elements without mechanical articulation between blade and body on the one hand and between blade and arm on the other hand.

Cette suspension est caractérisée en ce que la lame est fixée élastiquement sur la caisse par l'intermédiaire d'au moins un support d'articulation solidaire de la lame tandis que chaque extrémité de la lame repose sur le bras ou la caisse par l'intermédiaire d'un patin de caoutchouc. Le patin de caoutchouc peut être fixé sur la lame, sur le bras ou sur la caisse.This suspension is characterized in that the blade is fixed elastically to the body by means of at least one articulation support integral with the blade while each end of the blade rests on the arm or the body by means of a rubber pad. The rubber pad can be fixed on the blade, on the arm or on the body.

On a décrit ci-après, à titre d'exemple non limitatif, deux modes de réalisation de la suspension selon l'invention, avec référence aux dessins annexés dans lesquels
La Figure 1 est une vue en élévation, dans un
premier mode de réalisation;
La Figure 2 en est une vue en plan partielle;
La Figure 3 en est une coupe transversale sui
vant III-III de la Figure 2;
La Figure 4 est une vue en élévation d'un
second mode de réalisation.Two embodiments of the suspension according to the invention have been described below, by way of non-limiting example, with reference to the appended drawings in which
Figure 1 is an elevational view, in a
first embodiment;
Figure 2 is a partial plan view;
Figure 3 is a cross section following
vant III-III of Figure 2;
Figure 4 is an elevational view of a
second embodiment.

Aux Figures 1 à 3, on voit en 1 une lame élastique de suspension, par exemple en matériau composite, qui est fixée transversalement à la caisse 2 d'un véhicule par deux supports qui sont désignés au dessin d'une façon générale par la référence 3. Sur chacune des extrémités de la lame est collé un tam pon de caoutchouc 4 qui est en appui sur un bras de support de roue 5 monté pivotant par rapport à la caisse 2 autour d'un axe 6.In Figures 1 to 3, we see in 1 an elastic suspension blade, for example of composite material, which is fixed transversely to the body 2 of a vehicle by two supports which are generally designated in the drawing by the reference 3. A rubber tam 4 is stuck on each of the ends of the blade, which is supported on a wheel support arm 5 pivotally mounted relative to the body 2 about an axis 6.

Chacun des supports 3 comprend un support en tôle 7 qui est serré par des vis 8 sur la caisse 2. Sur le support 7 est adhérisé un élément en caoutchouc comprenant une embase 9, en demi-lune, qui est collée sur la lame 1 et réalisée en un matériau dur susceptible de supporter la déformation angulaire de la lame; entre le support et l'embase 9 a été injecté du caoutchouc mou 10 permettant la torsion et le déplacement latéral de la lame 1. Sous l'effet des charges correspondant à l'exploitation normale de la suspension, chaque point de l'extrémité de la lame 1 décrit unecourbe dont le centre de rotation se trouve sensiblement sur l'axe 11 de l'embase 9; les deux axes 11 sont disposés symétriquement par rapport à l'axe longitudinal 12 du véhicule et chacun d'eux est parallèle à l'axe 6 du bras de roue 5 corrrespondant et situé au voisinage de celui-ci.Each of the supports 3 comprises a sheet metal support 7 which is tightened by screws 8 on the body 2. On the support 7 is adhered a rubber element comprising a base 9, in a half-moon shape, which is glued to the blade 1 and made of a hard material capable of withstanding the angular deformation of the blade; between the support and the base 9 has been injected with soft rubber 10 allowing torsion and lateral movement of the blade 1. Under the effect of the loads corresponding to the normal exploitation of the suspension, each point of the end of the blade 1 describes a curve whose center of rotation is substantially on the axis 11 of the base 9; the two axes 11 are arranged symmetrically with respect to the longitudinal axis 12 of the vehicle and each of them is parallel to the axis 6 of the corresponding wheel arm 5 and located in the vicinity thereof.

A la Figure 4, la lame de suspension cantilever la est disposée parallèlement à l'axe longitudinal du véhicule. Cette lame est fixée en son milieu à la caisse 2 par un support 3 analogue à ceux du mode de réalisation des Figures 1 à 3. L'une des extrémités de la lame la porte un tampon élastique 4 qui est en appui sur le bras de roue 5; son autre extrémité repose sur la caisse par un tampon élastique 13. In Figure 4, the cantilever suspension blade la is arranged parallel to the longitudinal axis of the vehicle. This blade is fixed in the middle to the body 2 by a support 3 similar to those of the embodiment of Figures 1 to 3. One of the ends of the blade carries an elastic pad 4 which is supported on the arm of wheel 5; its other end rests on the body by an elastic pad 13.

Les lames 1 ou la peuvent étire en acier ou en matériau composite (fibres, verre, résine synthétique) à section constante (hauteur, largeur variables) ou à section variable et à profil quelconque. The blades 1 or 1a can be drawn from steel or from composite material (fibers, glass, synthetic resin) with constant section (variable height, width) or with variable section and any profile.

I1 va de soi que la présente invention ne doit pas étre considérée comme limitée aux deux modes de réalisation décrits et représentés, mais en couvre, au contraire toutes les variantes.  It goes without saying that the present invention should not be considered as limited to the two embodiments described and shown, but on the contrary covers all variants thereof.
