Abstract

Système de maintien d'un groupe motopropulseur de véhicule automobile, comportant un corps (2) présentant un alésage recevant une douille axiale (10) maintenue par l'intermédiaire d'un élastomère (12), une surface cylindrique de l'alésage du corps ou du contour extérieur de la douille (10) formant un premier élément, présente une gorge circulaire centrée autour d’un plan médian transversal (X-Z) recevant un bossage annulaire de l’élastomère (12), cet élastomère (12) comprenant axialement de chaque côté du bossage annulaire un creux détaché du premier élément, puis une nervure annulaire qui prend appui sur ce premier élément. Figure 1Maintenance system for a motor vehicle power unit, comprising a body (2) having a bore receiving an axial bushing (10) maintained by means of an elastomer (12), a cylindrical surface of the bore of the body or of the outer contour of the sleeve (10) forming a first element, has a circular groove centered around a transverse median plane (XZ) receiving an annular boss of the elastomer (12), this elastomer (12) comprising axially each side of the annular boss a hollow detached from the first element, then an annular rib which rests on this first element.
