Abstract

A torsion damping assembly comprises two coaxial parts mounted for relative angular rotation preferably including a hub web and a pair of annular guide members. Coil springs are chordally interposed between the coaxial parts. A friction washer is in axial contact with an axial load bearing component formed by one of the guide members or the hub web. An axially acting spring washer bears against the bearing component on the side of the bearing component remote from the friction washer and urges the friction washer toward the bearing component. The spring washer is axially interconnected with and detented to the retaining washer located on the other side of the bearing component. Preferably the retaining washer has resiliently deformable axial tabs which deflect for interconnecting the spring washer with the retaining washer. The retaining washer may be formed as a one-piece molded plastic part with the axial tabs. The spring washer is preferably disposed axially outside the guide washers for facilitating assembly.
