ABSTRACT:
A self-adjusting cover assembly for a friction clutch. The cover assembly includes three disc shaped members: a clutch cover, a secondary pressure plate and a primary pressure plate. Locking means, including jamming balls that releasably grip link pins, connect the primary pressure plate to the secondary pressure plate. Release lever actuated retractor means, associated with the secondary pressure plate, effect engagement and disengagement. During both the engagement and disengagement cycles the jamming balls release their hold on the link pins, thereby permitting relative axial movement between the two pressure plates. As wear occurs on the friction facings, the primary pressure plate will move axially relative to the secondary plate thereby compensating for the wear. A modification applies the principles of the invention to a cover assembly which does not include a secondary pressure plate.
