ABSTRACT:
Clutch disc for a motor vehicle friction clutch comprises a hub and a disc part enclosing the hub and coupled with predetermined play in rotation but otherwise non-rotatably with the hub. Side discs on axially opposite sides of the disc part form one unit mounted on the hub rotatably through a limited first angle relative to the disc part. The disc part is coupled rotationally elastically with the hub through at least one spring of an idling vibration damper. Several springs of an under-load vibration damper, arranged in windows of the disc part and of the two side discs, couple the side discs rotationally elastically with the disc part. The under-load vibration damper comprises a friction device having two control discs arranged on axially opposite sides of the disc part between the disc part and one each of the two side discs. The control discs are connected non-rotatably with one another. Relative rotation between the control discs and the disc part is limited to a second angle of rotation smaller than the first angle of rotation. At least one of the two control discs comprises at least one radially protruding extension co-operating with one of the springs of the under-load vibration damper.
