Abstract

Amortisseur (1) d'oscillations de torsion, comprenant deux étages d'amortissement (2, 3) montés en série, chaque étage d'amortissement (2, 3) présentant un composant d'entrée et un composant de sortie, le composant de sortie d'un étage d'amortissement étant mobile en rotation autour d'un axe (X) par rapport au composant d'entrée de cet étage d'amortissement à l'encontre d'organes de rappel élastique (4, 5), les organes de rappel élastique (4) du premier étage d'amortissement (2) étant radialement décalés par rapport aux organes de rappel élastique (5) du deuxième étage d'amortissement (3), l'amortisseur comprenant deux rondelles (10, 11) solidaires l'une de l'autre, et appartenant au composant de sortie du premier étage d'amortissement (2), la première (10) de ces deux rondelles présentant des zones de contact (22) avec une extrémité de chaque organe de rappel élastique (4) du premier étage d'amortissement (2), afin de transférer le couple vers le deuxième étage d'amortissement (3), et la deuxième (11) de ces deux rondelles étant dépourvue de telles zones de contact permettant la transmission du couple vers le deuxième étage d'amortissement, cette deuxième rondelle (11) comprenant une portion (25) participant au maintien en position des organes de rappel élastique (4) du premier étage d'amortissement (2).Torsional oscillation damper (1), comprising two damping stages (2, 3) connected in series, each damping stage (2, 3) having an input component and an output component, the output of a damping stage being movable in rotation about an axis (X) relative to the input component of this damping stage against elastic return members (4, 5), the elastic return members (4) of the first damping stage (2) being radially offset relative to the elastic return members (5) of the second damping stage (3), the damper comprising two washers (10, 11) integral with each other, and belonging to the output component of the first damping stage (2), the first (10) of these two washers having contact zones (22) with one end of each return member elastic (4) of the first damping stage (2), in order to transfer the torque to the second damping stage (3), and the second (11) of these two washers being devoid of such contact zones allowing the transmission of torque to the second damping stage, this second washer (11) comprising a portion (25) participating in the maintenance in position of the elastic return members (4) of the first damping stage (2).
