Abstract

L'invention concerne un amortisseur de torsion (1), destiné à une chaîne de transmission de véhicule automobile, comportant : - un premier et un deuxième éléments (2, 3) montés mobiles en rotation l'un par rapport à l'autre selon un axe de rotation X ; - un suiveur de came (11) relié au premier élément (2) ; - un organe élastique d'amortissement (14) agencé pour transmettre un couple et amortir les acyclismes de rotation entre le premier élément (2) et le deuxième élément (3) ; l'organe élastique (14) d'amortissement comportant une surface de came (13) coopérant avec le suiveur de came (11) et une liaison élastique reliant la surface de came au deuxième élément (3) ; - un dispositif de fin de course (18) apte à limiter la rotation relative du deuxième élément (3) par rapport au premier élément (3) selon un premier et un deuxième sens de rotation opposés ; le dispositif de fin de course (18) comportant : un élément en élastomère (27) permettant d'amortir les chocs en fin de course.The invention relates to a torsion damper (1) for a motor vehicle transmission chain comprising: - first and second elements (2, 3) mounted to rotate relative to one another according to the invention; an axis of rotation X; - a cam follower (11) connected to the first member (2); - A resilient damping member (14) arranged to transmit a torque and dampen the rotational acyclisms between the first member (2) and the second member (3); the resilient resilient member (14) having a cam surface (13) cooperating with the cam follower (11) and a resilient link connecting the cam surface to the second member (3); - A limit device (18) adapted to limit the relative rotation of the second element (3) relative to the first element (3) in a first and a second direction of rotation opposite; the end-of-stroke device (18) comprising: an elastomer element (27) for damping end-of-stroke impacts.
