Torsion damping assembly for automotive friction clutch plate

摘要

A torsion damping assembly for a friction clutch plate comprises two coaxial parts mounted for relative rotation within a predetermined range of angular displacement. Circumferentially acting springs including a resiliently deformable arm are circumferentially disposed between the coaxial parts. The resiliently deformable arm circumferentially extends from a support member fixed for rotation with one coaxial part and the free end of the arm is attached to the other coaxial part. A pair of axially spaced transverse surfaces are provided on each coaxial part. The support member is disposed axially between the respective pairs of transverse surfaces for maintaining the axial position of the coaxial parts relative to each other.
