Abstract:
A clutch cover assembly adapted to be coupled to a flywheel and selectively engaged with a friction member, said clutch cover assembly comprising:a clutch cover adapted to be fixedly coupled to the flywheel for rotation therewith, and axially opposed to the friction member, said clutch cover having a fulcrum movably coupled thereto;a pressure plate movably coupled to said clutch cover for movement in an axial direction;a pressing member supported by said clutch cover for acting on said pressure plate from the clutch cover side; anda wear compensating mechanism operatively disposed between said clutch cover and said pressure plate, said wear compensating mechanism being arranged to move said fulcrum on a clutch cover side of said pressing member toward the friction member by an amount corresponding to wear of the friction member during a clutch releasing operation, said wear compensating mechanism having a biasing mechanism, a stop mechanism and a wear amount detecting mechanism,said biasing mechanism biasing said fulcrum toward the friction member,said stop mechanism being frictionally engaged with said clutch cover so as to be axially movable, and arranged to prevent axial movement of said fulcrum by engaging said biasing mechanism,said wear amount detecting mechanism arranged to move said stop mechanism toward the friction member to form an axial space between said stop mechanism and said biasing mechanism when wear occurs on the friction member.
