Abstract:
A pressure plate assembly for a friction clutch, comprisinga housing for mounting to a flywheel having an axis of rotation, a pressure plate mounted in said housing with freedom to move axially, a stored energy element mounted in said housing and transmitting force along a path to said pressure plate to load said pressure plate toward said flywheel, a wear-compensating device in the path of force transmission between the stored energy element and the pressure plate, said wear-compensating device comprising at least one adjusting element which is movable in an adjusting direction to compensate for wear, a blocking element which is fixed in position relative to said housing, a gripping element fixed to said pressure plate, said gripping element blocking said at least one adjusting element against movement in said adjusting direction before wear occurs, said gripping element coming into contact with said blocking element when wear occurs, and means for positioning said blocking element with respect to said housing so that, when said housing is mounted to said flywheel, said blocking element can come into contact with said gripping element.
