Abstract:
An adjustment mechanism for a frictional clutch comprising:a pressure plate having an axis of rotation and an engagement surface substantially normal to the axis of rotation;a first annular cam member concentric with the axis of rotation and having a plurality of first ramped cam surfaces and being rotatively fixed with respect to the pressure plate;a second annular cam member rotatable relative to the first annular cam member and having a plurality of second ramped cam surfaces in engagement with the first ramped cam surfaces and together with the first annular cam member defining an effective pressure plate thickness relative to the engagement surface;a cam spring connected with the cam member and rotatively biasing the cam members toward an increased cam height; andan adjustment limiting mechanism havinga first plurality of pins axially extending from a side of the pressure plate opposite the engagement surface,an annular adjusting ring concentric with the axis of rotation disposed opposite the cam members from the pressure plate, anda first plurality of pin-receiving members fixed to the adjusting ring and slidably receiving the first plurality of pins.
