Clutch wear-compensating compound flywheel assembly

A clutch wear-compensating compound flywheel assembly, comprising:

• a first flywheel;
• a ring gear peripherally connected to said first flywheel so as to rotate through a predetermined angle relative to said first flywheel;
• a second flywheel connected to said first flywheel for unitary rotation and limited axial displacement relative to said first flywheel and bearing a friction facing against which a clutch disc is pressed;
• a clutch wear-gauging mechanism provided in an end surface of said first flywheel facing said clutch disc, for gauging wear of said clutch disc;
• an adjusting mechanism for inducing said second flywheel to move axially toward said clutch disc utilizing a cranking torque as transmitted by said ring gear, in cooperative response to said clutch wear-gauging mechanism, said adjusting mechanism including:
• wedging members contacting to drive said second flywheel toward said clutch disc;
• an engager arm in linkage with said clutch wear-gauging mechanism, one end of said engager arm being pivotally coupled to said ring gear and the other end of said engager arm selectively engaging one of said wedging members for wedging one of said wedging members against the other utilizing said cranking torque transmitted by said ring gear to move said second flywheel axially toward said clutch disc.
