Title
(EN) TORSION DAMPER AND CLUTCH DISC
(FR) AMORTISSEUR DE TORSION ET DISQUE D'EMBRAYAGE
Abstract
(EN)
A torsion damper (100) for a vehicle powertrain, comprising: - a first element (1) comprising a support element, and a second element (2, 2a, 2b) which can rotate with respect to the first element (1) about an axis X of rotation, - springs (4) mounted between the first element (1) and the second element (2, 2a, 2b) so as to compress to allow a relative rotation about the axis X between the first element (1) and the second element (2, 2a, 2b) , - a friction device (10) comprising a friction washer (11) provided with at least one fastening portion (12) fastened rigidly in rotation on a support element (13) of the first element (1), the friction washer (11) having a friction portion (15) having a friction track (16) backed up against a dorsal face (17) of the friction portion (15); and an elastic washer (18) arranged axially between the first element (1) and the dorsal face (17) of the friction portion (15), each portion (12) for fastening to the first element (1) being connected to the friction portion (15) by a flexible element (14) allowing an axial movement of the dorsal face (17) of the friction portion (15) with respect to the support element (13) of the first element (1).
