Self-adjusting clutch

A self-adjusting mechanism for use with an engine comprising:

• a pressure plate;
• a wear compensation plate;
• a wear sensor adjusting plate;
• a wear sensor mounted on a surface of said pressure plate and in contact with said wear compensation plate and said wear sensor adjusting plate, said wear sensor being movable with said pressure plate, said wear sensor adjusting plate and said wear compensation plate are each rotatable by kinetic energy relative to a change in a speed of the engine and moves away from the pressure plate by rotating around and relative to said pressure plate via a first screw thread and a second screw thread respectively, said wear sensor adjustment plate stopping rotation upon contact with a surface of said wear sensor;
• a plurality of adjustment rollers cooperative with said wear sensor adjustment plate so as to provide a unidirectional rotation for said wear sensor adjustment plate and to prevent rotation in an opposite direction;
• and
• a diaphragm spring urging a force against said wear compensation plate so as to maintain an initial position of said wear compensation plate, said diaphragm spring adapted to release the force on said wear compensation plate;
• and
• a clutch cover lug in contact with the surface of said wear sensor.
