Title:
FRICTION CLUTCH
Document Type and Number:
WIPO Patent Application WO2000034675
Kind Code:
A3
Abstract:
A friction clutch comprises a clutch cover (21) attached to a flywheel with at least one spring acting on a pressure plate (13) to force a driven plate into frictional engagement with the flywheel. The clutch has at least one constant lift device (49, fig. 1) which limits lift of the pressure plate to a substantially constant value during each full disengagement of the clutch. The constant lift device is of the type which comprises a locking plate (60) pivotally mounted to one of either a wear sensing means, the pressure plate (13) or an axially fixed component of the clutch (132, fig. 7). The locking plate (60) has a hole (63) through which a pin (51) extends, and spring means (53) acting to tilt the locking plate relative to the pin to grip the pin to prevent axial movement of the pin relative to the locking plate in at least one direction. Resilient means (53C, fig. 6) is provided to eliminate or reduce free play in the pivotal mounting of the locking plate. The friction clutch may comprise an automatically adjusting clutch.
