Abstract
A clutch cover assembly 3 includes a clutch cover 12, a pressure plate 10, a pin 33, a diaphragm spring 11 and a coil spring 34. The pin 33 extends in an axial direction and its one end is fixed to at least one of the flywheel 1 and the clutch cover 12. The pin 33 also connects with the pressure plate 10 in a manner such that relative rotation between the pressure plate 10 and the clutch cover 12 is restricted but limited axial movement is possible. A diaphragm spring 11, supported by the clutch cover 12, presses the pressure plate 10 toward the flywheel 1. The coil spring 34 is a mechanism which release the pressure plate 10 from the flywheel 1 side, when the diaphragm spring 11 stops pressing the pressure plate 10.
Claims12
A clutch cover assembly connected to a flywheel in a clutch mechanism, comprising:
- a clutch cover fixed to said flywheel,
- a pressure plate disposed inside said clutch cover, said pressure plate formed with a friction surface facing said flywheel;
- a connecting element which extends in a generally axial direction relative to an axis of rotation of said clutch cover and said flywheel, a first end of said connecting element being connected to said flywheel and a second end of said connecting element being supported by said clutch cover, said connecting element extending through a portion of said pressure plate, said connecting element contacting said pressure plate restricting relative rotation between said clutch cover, said flywheel and said pressure plate, and allowing axial movement of said pressure plate with respect to said clutch cover;
- a diaphragm spring disposed in said clutch cover between said clutch cover and said pressure plate, said diaphragm spring biasing said pressure plate toward said flywheel;
- and
- a releasing mechanism supported in said clutch cover, said releasing mechanism configured to bias said pressure plate away from said flywheel in response to movement of said diaphragm spring wherein said connecting element provides support for said pressure plate in transmission of torque between said clutch cover and said flywheel, and said pressure plate.
