Abstract:
A clutch cover assembly adapted to be attached to a flywheel for engaging and disengaging a friction member with and from the flywheel, said clutch cover assembly comprising:a clutch cover configured and adapted to be fixedly coupled to the flywheel to rotate therewith; a pressure plate movably coupled to said clutch cover in an axial direction and fixedly coupled to said clutch cover in a rotational direction to rotate; a pushing member movably disposed between said clutch cover and said pressure plate to apply a pushing force on said pressure plate that is directed away from said clutch cover; and a wear compensating mechanism operatively disposed between said clutch cover and said pushing member to axially move a support portion of said pushing member directed away from said clutch cover by an amount corresponding to an amount of wear occurring of the friction member, said wear compensating mechanism including a first inclined surface disposed on a friction member facing side of said clutch cover and extending in a rotating direction, a first ring member rotatably and axially movable with respect to said clutch cover, and having a second inclined surface in complementary contact with said first inclined surface, a biasing member arranged to urge said first ring member in the rotating direction with respect to said clutch cover such that said first ring member moves axially away from said clutch cover, and a restricting mechanism arranged to contact a friction member facing side of said first ring member to selectively control axial movement of said first ring member toward the friction member such that axial movement of said first ring member toward the friction member occurs when the friction member is worn.
