Abstract
A clutch cover assembly comprises a generally annular cover by which it is attached to a flywheel. A generally annular pressure plate is axially movable relative to the cover but constrained to rotate with it. An engagement device urges the pressure plate in the axial direction away from the cover. It is formed at least in part by an axially acting spring arrangement comprising at least two Belleville washers. These are disposed radially one inside the other with the larger diameter edge of one Belleville washer lying on a circumference of smaller diameter than the circumference on which lies the smaller diameter edge of the other Belleville washer.
