CLUTCH ADJUSTMENT SYSTEM WITH WEAR RESISTANT FEATURES FOR BACK DRIVING PREVENTION

A friction clutch for a motor vehicle includes an adjustment mechanism compensating for wear of a friction disk. The adjustment mechanism (40) includes a first cam ring (52) rotatably fixed and a second cam ring (54) rotatable relative to the first cam ring (52). Both cam rings (52,54) have a plural...

Zusammenfassung:	A friction clutch for a motor vehicle includes an adjustment mechanism compensating for wear of a friction disk. The adjustment mechanism (40) includes a first cam ring (52) rotatably fixed and a second cam ring (54) rotatable relative to the first cam ring (52). Both cam rings (52,54) have a plurality of cam surfaces configured such that rotation of the second cam ring (54) relative to the first cam ring (52) varies a height of the adjustment mechanism (40). A torsion spring (60) applies a biasing force to the second cam ring (54). A back drive prevention assembly (70) includes a back drive spring (80) attached to the pressure plate and first cam ring (52) to prevent back drive of the second cam ring (54) through a baffle (62) including a plurality of cam teeth (72) formed on a bottom surface of the baffle (62). The cam teeth (72) are formed at an angle A relative to a bottom surface of the baffle (62) decreasing displacement and loads of the back drive spring (80).
