Abstract
A friction clutch having a known type of self-adjusting release mechanism is provided with means for preventing adjustments caused by extraneous forces rather than disc wear. In the known mechanism, adjustment is effected by a pair of ring members carried by the release mechanism, one of the ring members being rotatable relative to the other in response to disc wear to effect the compensating adjustment. The invention provides coacting means on the two ring members operable by centrifugal force to lock the members together at engine idle speed whereby adjustments induced by extraneous forces rather than actual disc wear are prevented.
Claims4
In a friction clutch for connecting driving and driven shafts, the clutch having means for normally effecting a driving connection between the shafts and a release mechanism axially slidable on the driven shaft for disengaging said driving connection, the release mechanism including first and second adjustment effecting members one of which is rotatable with respect to the other to compensate for wear occurring in the driving connection;
- the improvement comprising means for preventing relative rotation between the adjustment effecting members when the speed of the driving shaft is in excess of a predetermined number of r.p.m.'s, said prevention means including means rockably connected to one of the adjustment effecting members and movable by centrifugal force into latching engagement with the other member.
