ABSTRACT:
An adjustment mechanism for a frictional clutch includes a pressure plate, a first annular cam member, a second annular cam member, a cam spring and an adjustment limiting mechanism. The pressure plate includes an axis of rotation and an engagement surface substantially normal to the axis of rotation. The first annular cam member is concentric with the axis of rotation and has a plurality of first ramped cam surfaces. The first annular cam member is rotatably fixed with respect to the pressure plate. The second annular cam member is rotatable relative to the first annular cam member and has a plurality of second ramped cam surfaces in engagement with the first ramped cam surfaces. The second annular cam member, together with the first annular cam member defines an effective pressure plate thickness relative to the engagement surface. The cam spring is connected with the cam member and rotatably biases the cam members toward an increased cam height. The adjustment limiting mechanism includes a first plurality of pins, an annular adjusting ring, and a first plurality of pin receiving members. The first plurality of pins extends axially from a side of the pressure plate opposite the engagement surface. The annular adjusting ring is concentric with the axis of rotation. The first plurality of pin receiving members is fixed to the adjusting ring and slidably receives the first plurality of pins.
