Abstract
A pressure plate assembly includes a housing designed to be attached to a flywheel; a pressure plate mounted in the housing with freedom to move in a direction parallel to an axis of rotation; a stored-energy device; and a wear take-up device acting in the path of force transmission between the stored-energy device and the pressure plate, where the wear take-up device has at least one take-up element which can be moved in a take-up direction to compensate for wear. A play sensor arrangement includes a detection element provided on the pressure plate, which element, upon the occurrence of wear, makes contact or can be brought into contact with a blocking element, which is fixed in position with respect to the housing arrangement. The blocking element has a fastening area, by which it is fixed in position with respect to the housing arrangement, and a contact area, by which it makes contact with the detection element. The blocking element also has a support area so that the element can be supported with respect to the housing arrangement.
