Title
(EN) TORSIONAL DAMPER FOR CLUTCH, IN PARTICULAR FOR MOTOR VEHICLE
(FR) AMORTISSEUR DE TORSION POUR EMBRAYAGE, EN PARTICULIER POUR VEHICULE AUTOMOBILE
Abstract
(EN)
The invention concerns a torsional damper for clutch, in particular for motor vehicle, comprising a main damper linking an input element (10) to an annular disc (18) enclosing a hub (12) capable of being locked in rotation with an output shaft and a pre-damper (28) interposed between the disc and the hub, and a cylindrical ring (56) forming a centring bearing for a guide washer (16) whereon is fixed the input element (10) and comprising axial teeth (62) meshing with a toothing of the hub (12) with a circumferential clearance less than that provided between the toothing (46) of the disc (18) and the toothing (44) of hub (12) to brake and absorb the shocks of said toothing on each other.
(FR)
Amortisseur de torsion pour embrayage, en particulier pour véhicule automobile, comprenant un amortisseur principal reliant un élément d'entrée (10) à un voile annulaire (18) entourant un moyeu (12) solidarisable en rotation avec un arbre mené, et un pré-amortisseur (28) interposé entre le voile et le moyeu, et une bague cylindrique (56) formant palier de centrage d'une rondelle de guidage (16) sur laquelle est fixé l'élément d'entrée (10) et comprenant des dents axiales (62) engrènant avec une denture du moyeu (12) avec un jeu circonférentiel inférieur à celui prévu entre des dentures (46) du voile (18) et (44) du moyeu (12) pour freiner et amortir les chocs de ces dentures l'une sur l'autre.
