Clutch disk for motor vehicle, has recess in front side of friction element so that contact surface frictionally fitted to side windows or driver disk is smaller than surface of front side projecting in axial direction

摘要

The disk has a driver disk arranged on a hub part and connected with a lining support supporting a friction pad. Two axially spaced side windows are arranged on the hub part, and the driver disk is arranged between the windows. A torsion spring is arranged between the driving disk and windows. The side windows and/or driver disk are adjoined to front side of a circular friction element (9). A recess (13'') i.e. slot, is in the front side so that a contact surface frictionally fitted to the windows or driver disk is smaller than a surface of the front side projecting in an axial direction.
