ABSTRACT:
A combined mechanical and centrifugal clutch for a motor driven vehicle which has several original equipment manufacturer's components including an inside and an outside pressure plate (70), also frictional material for transmitting torque through the clutch. A lock-up housing (84) is attached to the outside pressure plate and contains a number of pivotally connected camming fingers (100) that force the outside pressure plate into tensional contact wit the frictional material by the camming force of the fingers caused by rotational centrifugal force. The operational portion of the mechanical clutch is unaltered permitting mechanical release of the clutch with the centrifugal portion added to lock-in the torque transmitting capabilities permitting increased capacity and positive engagement. Selecting the optimum rotational engagement speed is achieved by the use of weights and altering the springs or changing spring compressibility.
