An apparatus (10) includes a vehicle drive shaft (12), a roller bearing (16) supporting the drive shaft (12) for rotation, and a housing (18) which contains and supports the roller bearing (16) in a vehicle. The roller bearing (16) includes an inner race (34) rotatable within an outer race (36). The apparatus (10) further includes a damper assembly (20) which damps vibrations radially between the roller bearing (16) and the housing (18). The damper assembly (20) defines a closed chamber (150) containing rheological fluid (152), and has a flow-inducing part (80) projecting into the fluid (152). The flow-inducing part (80) of the damper assembly (20) is movable radially within the fluid (152) in response to radial vibrations of the outer bearing race (36).
Cette invention concerne un dispositif (10) qui comprend un arbre moteur (12), un roulement à billes (16) servant à soutenir l'arbre moteur (16) et un logement (18) renfermant ledit roulement à billes (16) et servant à le fixer à un véhicule. Le roulement à billes (16) comporte une bague intérieure (34) tournant à l'intérieur d'une bague extérieure (36). Le dispositif comprend en outre un montage amortisseur (20) servant à atténuer les vibrations radiales entre le roulement à billes (16) et le logement (18). Ce montage amortisseur (20) définit une enceinte fermée (150) renfermant un fluide visqueux (152) dans laquelle est plongée une pièce mobile (80) qui se déplace radialement à l'intérieur de ledit fluide visqueux (152) en réponse aux vibrations radiales de la bague extérieure (36) du roulement.
