Abstract

L'invention concerne un Ensemble pour un amortisseur de torsion destiné à une chaîne de transmission de véhicule automobile, ledit ensemble comportant : - un premier élément (1) destiné à être monté en rotation par rapport à un second élément (2) autour d'un axe de rotation X, - une lame (4) comportant une portion de montage (8) montée fixe sur le premier élément (1) et une portion flexible (9) destinée à coopérer avec un suiveur de came (6) pour transmettre un couple entre le premier élément (1) et le second élément (2), - une pièce élastique (16) portée par l'un parmi la lame (4) et le premier élément (1), la pièce élastique (16) étant agencée dans une zone de déplacement de la portion flexible (9) de la lame (4) entre la portion flexible (9) de la lame (4) et un support fixe porté par le premier élément (1) et de manière à, lors d'une flexion de la portion flexible (9) de la lame (4), exercer sur la lame (4) une force de rappel élastique s'opposant au fléchissement de la portion flexible (9) de la lame (4).
