    摘要: An adjustment mechanism for a clutch is positioned between the diaphragm spring and the pressure plate, the adjustment mechanism including: a first cam ring rotatably fixed with respect to the pressure plate, a second cam ring rotatable relative to the first cam ring and both cam rings having a plurality of cam surfaces configured such that rotation of the second cam ring relative to the first cam ring varies a height of the adjustment mechanism, and a torsion spring including a longitudinal axis. The torsion spring is disposed in the annular groove. The torsion spring includes a helical round cylindrical body that extends to a first end connected to the first cam ring and the torsion spring has a second end connected to the pressure plate. The torsion spring applies a biasing force to the second cam ring promoting rotation of the second cam ring relative to the first cam ring. The pressure plate includes a locking slot formed therein partially through the pressure plate and through the opposing surface. The locking slot is formed at an angle relative to the opposing surface and the second end of the torsion spring includes a locking hook formed thereon. The locking hook extends perpendicular to the longitudinal axis of the torsion spring. The locking hook is disposed in the locking slot fixing the locking hook relative to the pressure plate.
