    • A clutch cover assembly 4 is provided to maintain accurately a desired amount of movement of a fulcrum on a clutch cover side of a pressing member moved in a wear compensating mechanism. The clutch cover assembly 4 includes a wear compensating mechanism 18. The wear compensating mechanism 18 has a biasing mechanism 31 for biasing the support ring 36 toward the clutch disk assembly 3, a stop mechanism 32 axially movably and frictionally engaged with a clutch cover, and a wear amount detecting mechanism 33. The stop mechanism 32 can stop the axial movement of the support ring 36 by receiving the biasing mechanism 31, and forms a space with respect to the biasing mechanism 31 by moving toward the clutch disk assembly 3 when wear occurs in the clutch disk assembly 3. The wear amount detecting mechanism 33 moves the stop mechanism 32 toward the clutch disk assembly 3 when the wear occurs, and thereby forms an axial space between the stop mechanism 32 and the biasing mechanism 31.

    • A clutch cover assembly 1 is provided with a biasing mechanism 24 disposed between a pressure plate 22 and a fulcrum ring 23 for biasing the fulcrum ring 23 axially away from the pressure plate 23. The biasing mechanism 24 includes a first support plate 31, a second support plate 32, and return springs 33. The first and second support plates 31 and 32 are movable relative to each other in the circumferential direction. The first and second support plates 31 and 32 include first and second tilted surfaces 31a and 32a, respectively, that abut on each other. The return springs 33 are disposed in an inner circumference of the first and second support plates 31 and 32. Each return spring 33 is a tension spring which biases the first and the second support plates 31 and 32 relative to each other in the circumferential direction. Thus, clutch cover assembly 1 is equipped with a wear compensation mechanism that has a simplified biasing mechanism 24 located between the fulcrum ring 23 and the pressure plate 22.

    • In a friction clutch including a diaphragm spring for urging a pressure plate into pressing a clutch disk against a flywheel, a support ring member for supporting the diaphragm spring from the back with respect to the clutch cover is normally urged toward the pressure plate, but restrained by a resilient spacer member which is provided on the pressure plate. The resilient spacer member normally restrains the support ring member against the urging force but, once the clutch disk is worn and the pressure plate is thereby caused to move closer to the flywheel, allows the support ring member to move toward the pressure plate by a distance corresponding to the wear in the clutch disk. The back support point of the diaphragm spring is thus moved toward the flywheel according to the amount of wear which develops in the facing members of the clutch disk, and this adjusting action can be achieved with a simple arrangement and in an stable and immediate manner.
    • 在包括用于推压压板将离合器盘压靠在飞轮上的膜片弹簧的摩擦离合器中,用于相对于离合器盖从背面支撑膜片弹簧的支撑环构件通常被推向压板,但是被限制 通过设置在压力板上的弹性间隔件。 弹性分隔件一般通过限制支撑环构件抵抗推力,但是一旦离合器盘磨损并且压板因而使其靠近飞轮移动,则允许支撑环构件向压板移动一定距离 对应于离合器盘的磨损。 因此,隔膜弹簧的后支撑点根据在离合器盘的相对构件中产生的磨损量而朝向飞轮移动,并且可以以简单的布置并且以稳定且立即的方式实现该调节动作。
