Une suspension de véhicule automobile est généralement constituée d'un ressort de suspension pour soutenir la masse suspendue du véhicule, d'un amortisseur pour amortir les déplacements relatifs entre la masse suspendue et la masse non suspendue du véhicule, et de deux butées, généralement constituée par un élément élastique de compression, associée à l'amortisseur pour limiter l'amplitude des déplacements relatifs entre masse suspendue et masse non suspendue aussi bien en A motor vehicle suspension generally consists of a suspension spring to support the suspended mass of the vehicle, a shock absorber to dampen the relative displacements between the suspended mass and the unsprung mass of the vehicle, and two stops, generally consisting by an elastic compression element, associated with the shock absorber to limit the amplitude of the relative displacements between suspended mass and unsprung mass as well in
compression qu'en détente.compression than in relaxation.
Dans le cas d'une suspension selon laquelle la tige de l'amortisseur est liée au châssis du véhicule, tandis que le cylindre constituant le corps de l'amortisseur est lié à un support de la fusée de roue, qui peut être constitué par un bras de suspension, la butée de compression est interposée entre le support de la fusée de roue et la caisse du véhicule en étant comprimée le long de la tige d'amortisseur coaxialement à celleci entre une paroi transversale d'appui solidaire du corps de l'amortisseur à l'extrémité supérieure de celui-ci et un bol d'expansion lié rigidement à la fixation de la In the case of a suspension according to which the rod of the shock absorber is linked to the chassis of the vehicle, while the cylinder constituting the body of the shock absorber is linked to a support of the wheel spindle, which can be constituted by a suspension arm, the compression stop is interposed between the wheel spindle support and the vehicle body by being compressed along the shock absorber rod coaxially therewith between a transverse support wall secured to the body of the shock absorber at the upper end of it and an expansion bowl rigidly linked to the fixing of the
tige d'amortisseur à la caisse du véhicule. shock absorber rod at the vehicle body.
Selon cet agencement connu, la butée de compression intervient directement dans l'empilage de l'amortisseur en augmentant ses cotes mortes de la valeur de longueur de la butée complètement comprimée additionnée de According to this known arrangement, the compression stop intervenes directly in the stacking of the shock absorber by increasing its dead dimensions by the length value of the fully compressed stop added with
l'épaisseur de la paroi transversale d'appui de la butée. the thickness of the transverse bearing wall of the stop.
Cette paroi d'appui doit en outre comporter des canaux d'évacuation d'air expulsé par la compression de la butée pour empêcher l'entrée sous pression d'air ou de particules étrangères dans l'amortisseur à travers les moyens d'étanchéité de la tige relativement au cylindre This support wall must furthermore comprise channels for evacuating air expelled by the compression of the stop to prevent the entry of air or foreign particles under pressure into the damper through the sealing means of the rod relative to the cylinder
de l'amortisseur.of the shock absorber.
La présente invention a pour but d'éliminer les inconvénients ci-dessus des suspensions connues en proposant un dispositif à butée de limitation de course pour amortisseur du véhicule automobile qui est agencé de façon que la butée de compression ne fasse plus partie des cotes mortes de l'amortisseur, d'o une amélioration substantielle de la compacité du train avant ou arrière The object of the present invention is to eliminate the above drawbacks of known suspensions by proposing a device with a stroke limitation stop for a shock absorber of the motor vehicle which is arranged so that the compression stop no longer forms part of the dead dimensions of the shock absorber, hence a substantial improvement in the compactness of the front or rear axle

De préférence, le bol de logement de la butée de compression comprend deux parois concentriques respectivement externe et interne raccordées l'une à l'autre par une paroi annulaire transversale d'appui de la butée de compression, de façon à définir approximativement, en section longitudinale, la forme d'un U, la paroi interne du bol étant solidaire de la surface latérale correspondante du corps de l'amortisseur. Dans le cas o la butée de compression est interposée entre le châssis du véhicule et le corps de l'amortisseur, la coupelle de précontrainte de la butée est solidaire d'un support de suspension fixé à la caisse, le support de suspension étant l'appui d'une extrémité d'un ressort de suspension dont l'extrémité opposée prend appui sur une collerette solidaire du corps To this end, according to the invention, the device with a stroke limitation stopper for a motor vehicle shock absorber, where the stopper is an elastic compression element interposed, coaxially with the rod of the shock absorber, between the chassis of the vehicle to which is linked the shock absorber rod and the shock absorber body linked to a wheel stub support or between the shock absorber body linked to the chassis and the wheel stub support to which the shock absorber rod is linked, is characterized in that the compression stop is arranged around the body of the shock absorber in a bowl secured to this body and is held prestressed in the bowl by a cup linked to the chassis or to the wheel support. Preferably, the bowl for housing the compression stop comprises two concentric walls, respectively external and internal, connected to each other by a transverse annular support wall of the compression stop, so as to define approximately, in section longitudinal, the shape of a U, the internal wall of the bowl being integral with the corresponding lateral surface of the body of the shock absorber. In the case where the compression stop is interposed between the vehicle chassis and the body of the shock absorber, the pre-stressing cup of the stop is secured to a suspension support fixed to the body, the suspension support being the support of one end of a suspension spring, the opposite end of which bears on a collar secured to the body
