Abstract
A friction clutch for a motor vehicle includes an adjustment mechanism compensating for wear of a friction disk. The adjustment mechanism () includes a first cam ring () rotatably fixed and a second cam ring () rotatable relative to the first cam ring (). Both cam rings () have 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 (). A torsion spring () applies a biasing force to the second cam ring (). A back drive prevention assembly () includes a back drive spring () attached to the pressure plate and first cam ring () to prevent back drive of the second cam ring () through a baffle () including a plurality of cam teeth () formed on a bottom surface of the baffle (). The cam teeth () are formed at an angle A relative to a bottom surface of the baffle () decreasing displacement and loads of the back drive spring ().
