Abstract

L'invention concerne un Amortisseur de torsion pour dispositif de transmission de couple comportant : - un premier élément (1) et un deuxième élément (2) mobiles en rotation l'un par rapport à l'autre autour d'un axe de rotation X ; et - un organe élastique d'amortissement (6, 7) pour transmettre un couple et amortir les acyclismes entre le premier élément (1) et le deuxième élément (2), l'amortisseur de torsion étant caractérisé en ce qu'il comporte un dispositif de fin de course comportant une lame (11) élastique agencée de sorte à être à distance d'une surface de butée (29) lorsque le débattement angulaire entre le premier élément (1) et le deuxième élément (2) est inférieur à un seuil de débattement (33) et sollicitée et déformée élastiquement pour générer une force de rappel élastique agissant à l'encontre du débattement angulaire entre le premier élément (1) et le deuxième élément (2) lorsque ledit débattement angulaire est supérieur audit seuil de débattement (33).
