Abstract:
A pressure plate subassembly for urging a clutch disk against a flywheel in a friction clutch with automatic wear compensation, said pressure plate subassembly comprising a plurality of components including:a housing connectable with the flywheel of the friction clutch for joint rotation about an axis of rotation;a pressure plate rotatably mounted in said housing for rotating about said axis of rotation relative to said housing and being axially displaceable relative to said housing;an accumulator operatively supportably arranged between said housing and said pressure plate for urging said pressure plate toward a side of said housing that is connectable to the flywheel;a wear readjusting device arranged between said accumulator and said pressure plate comprising a readjusting element displaceable for compensating for wear of the clutch disk of the friction clutch; anda clearance transmitter arrangement having a readjusting arrangement operatively connected for cooperating with said wear readjusting device, said clearance transmitter arrangement further comprising a ring element encircling the axis of rotation and engaging one of said plural components including a wear-registering arrangement interactable with one of another of said plural components and the flywheel of the friction clutch for registering the wear of said clutch disk,wherein said ring element is axially displaceable with respect to said one of said plural components and said readjusting arrangement is mounted on the ring element and is operatively connected with said wear readjusting device for permitting displacement of said readjusting element in response to the wear of the clutch disk, andwherein said wear-registering arrangement comprises a plurality of wear-registering sections.
