Title (EN) TORSION DAMPER, IN PARTICULAR FOR A MOTOR VEHICLE CLUTCH
(FR) AMORTISSEUR DE TORSION, NOTAMMENT POUR UN EMBRAYAGE D'UN VEHICULE AUTOMOBILE
Abstract:
(EN) The invention relates to a damper, in particular a torsion damper, especially for a motor vehicle clutch, comprising: - a first part (2) and a second part (3) that can rotate relative to each other about an axis of rotation (X); - at least one transmission member (60) that is deformable and can transmit torque between the two parts in a damped transmission phase in which the first and second parts rotate relative to each other about the axis of rotation (X), the damper being characterized in that it comprises an end stop (50a) for at least a first direction of relative rotation between the first and second parts, said end stop (50a) allowing the first and second parts to gradually abut against each other and being provided with a deformable part (51a) that includes a leaf spring.
(FR) L'invention a pour objet un amortisseur, notamment un amortisseur de torsion, notamment pour un embrayage d'automobile, comprenant : - un premier (2) et un second élément (3) mobiles en rotation l'un par rapport à l'autre autour d'un axe de rotation (X); - au moins un organe de transmission (60) capable, dans une phase de transmission avec amortissement dans la quelle les premier et second éléments tournent l'un par rapport à l'autre selon l'axe de rotation X, de se déformer et de transmettre un couple entre ces deux éléments, l'amortisseur étant caractérisé en ce qu'il comporte, pour au moins un premier sens de rotation relative des premier et second éléments, un dispositif de fin de course (50a) permettant une mise en butée progressive entre les premier et second éléments, le dispositif de fin de course comportant un élément déformable (51a) doté d'une lame élastique.
