Abstract
A clutch cover assembly 1 having a wear compensating mechanism having accurate wear compensation is provided. In the clutch cover assembly 1, a restricting mechanism 25 restricts movement of a pressure plate 22 away from a friction facing 11 in a clutch release operation. The restricting mechanism 25 is configured to detect an amount of wear of the friction facing 11, and to shift a stopping position of the pressure plate 22 moving away from the friction facing 11 in accordance with the wear amount toward the friction facing 11. A strap plate 26 biases the pressure plate 22 away from the friction facing 11. A leaf spring 35 axially biases the pressure plate 22 and the fulcrum ring 23 toward each other.
Claims21
A clutch cover assembly for biasing a friction facing of a clutch disk assembly toward a flywheel to engage a clutch, comprising:
- a clutch cover being fixed to said flywheel;
- a pressure plate neighboring said friction facing, and having a first side surface opposed to said friction facing and a second side surface on an opposite side;
- a fulcrum ring being arranged on said second side surface of said pressure plate;
- a pushing member being supported by said clutch cover to apply a pushing force to said fulcrum ring toward said pressure plate;
- a biasing mechanism to apply a load to said fulcrum ring to bias said fulcrum ring away from said pressure plate;
- a restricting mechanism to restrict movement of said pressure plate away from said friction facing in a clutch release operation, to detect a wear amount of said friction facing, and to shift a stopping position of said pressure plate moved away from said friction facing in accordance with said wear amount toward said friction facing;
- a first elastic member to bias said pressure plate away from said friction facing;
- and
- a second elastic member to bias said pressure plate and said fulcrum ring axially toward each other.
7 The clutch cover assembly according to claim 4, wherein
- said plate spring has one end fixed to said pressure plate and an other end engaging with said pushing member.
The clutch cover assembly according to claim 7, wherein
- said plate spring has two curved portions connected to each other.
The clutch cover assembly according to claim 7, wherein
- said fulcrum ring is formed with an abutting portion abutting with a pushing portion of said pushing member and a recessed portion having a space from said pushing portion of said pushing member, and
- a portion of said plate spring passes through said space.
20 The clutch cover assembly according to claim 1, wherein
- said pushing member stops the movement of said fulcrum ring away from said pressure plate during an operation of compensating wear in said clutch release operation.
