Abstract:
A pressure plate assembly for a friction clutch, comprisinga housing having an axis of rotation, a pressure plate mounted in said housing with freedom to move axially relative to said housing, a stored energy element mounted in said housing and transmitting force along a path from said housing to said pressure plate, a wear-compensating device in the path of force transmission, 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 can be fixed in position relative to said housing, a gripping element attached 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, an arresting element which can be shifted in an arresting direction when said gripping element comes into contact with said blocking element, thereby arresting the gripping element in a position corresponding to the amount of wear which has occurred, and transport securing means for preventing at least one of moving the adjusting element in the adjusting direction and moving the arresting element in the arresting direction prior to attaching the housing to a centrifugal mass, said transport securing means comprising at least one of means for releasing said adjusting element for movement in the adjusting direction by the action of centrifugal force on said arresting element, and means for releasing the arresting element for movement in the arresting direction by the action of centrifugal force on the arresting element.
