Abstract

Amortisseur de torsion pour dispositif de transmission de couple, notamment pour automobile, en particulier pour un dispositif d'embrayage, l'amortisseur comportant : - un premier élément (3) mobile en rotation autour d'un axe de rotation (X), - un second élément (2) mobile en rotation autour de l'axe de rotation (X), et mobile en rotation par rapport au premier élément autour de l'axe de rotation (X), - un bras (81) relié par une liaison élastique (82) au second élément de l'amortisseur, ce bras comportant une surface de came (20) agencée pour coopérer, lors l'une rotation relative entre les premier et second éléments, avec un suiveur de came (24) afin de permettre le transfert de couple entre le premier et second élément, caractérisé en ce qu'au moins une partie de la portion du bras le long de laquelle s'étend la surface de came, dite portion de transmission (83), présente au moins une zone de densité réduite (84).Torsion damper for a torque transmission device, in particular for a motor vehicle, in particular for a clutch device, the damper comprising: - a first element (3) movable in rotation about an axis of rotation (X), - a second element (2) movable in rotation around the axis of rotation (X), and movable in rotation with respect to the first element around the axis of rotation (X), - an arm (81) connected by a link elastic (82) to the second element of the shock absorber, this arm comprising a cam surface (20) arranged to cooperate, during relative rotation between the first and second elements, with a cam follower (24) in order to allow the transfer of torque between the first and second element, characterized in that at least part of the portion of the arm along which the cam surface extends, called the transmission portion (83), has at least one zone of reduced density (84).
