Abstract:
A thrust plate assembly, comprising:a housing fixed to a flywheel for joint rotation about an axis of rotation;a pressure plate in the housing fixed with respect to rotation relative to it and axially displaceable relative to it;an energy accumulator having one side supported at the housing and another side supported at the pressure plate so as to press the pressure plate in a direction of a side of the housing provided for connection with the flywheel;a wear adjustment device arranged in a support path of the energy accumulator between the energy accumulator and one component of the housing and the pressure plate, the wear adjustment device including at least one adjustment element which is displaceable for purposes of wear compensation and is pretensioned in a wear adjusting direction;at least one play sensor arrangement for detecting wear in friction linings of a clutch disk which can be clamped between the pressure plate and the flywheel, the play sensor arrangement including a locking/detection element arranged on the one component and pretensioned against the wear adjustment device with a locking portion so as to act upon the wear adjustment device in order to prevent a movement of the at least one wear adjustment element in the wear adjusting direction and which is interactable via a detection portion with another component for detection of wear, the another component being displaceable with respect to the one component when wear occurs, the locking/detection element being movable into a position for releasing the at least one adjustment element for movement in the wear adjusting direction when wear occurs by interaction with the another component; anda stopping element arranged so as to lock the locking/detection element against movement in its pretensioning direction when the locking/detection element is brought into the position for releasing the at least one adjustment element.
