Abstract

L'invention a pour objet un amortisseur, notamment pour un embrayage d'automobile, comprenant : - un élément d'entrée et un élément de sortie mobiles en rotation l'un par rapport à l'autre autour d'un axe de rotation (X); - des moyens d'amortissement pour transmettre un couple et amortir les acyclismes de rotation entre les éléments d'entrée et de sortie ; ledit amortisseur étant caractérisé en ce que les moyens d'amortissement comportent une lame élastique (122) et cette lame élastique est formée par un empilement de lamelles, l'épaisseur de chaque lamelle (123) étant inférieure à 15 mm, de préférence inférieure à 10 mm.The subject of the invention is a shock absorber, in particular for an automobile clutch, comprising: an input element and an output element that are rotatable relative to one another about an axis of rotation ( X); damping means for transmitting torque and damping rotation acyclisms between the input and output elements; said damper being characterized in that the damping means comprise an elastic blade (122) and this elastic blade is formed by a stack of lamellae, the thickness of each lamella (123) being less than 15 mm, preferably less than 10 mm.
