ABSTRACT:
A centrifugally actuated wet plate clutch which is actuated by the centrifugal pressure of its cooling and lubricating fluid. An input housing defines a radial cavity which is partially filled with the fluid and contains sets of interleaved clutch plates respectively mounted to the housing and to an output shaft which is rotatable independent of the housing. A piston adapted to urge the clutch plates together is mounted in the cavity and has a net piston surface opposing the clutch plates. When the housing is accelerated in rotational speed, centrifugal pressure develops in the fluid and acts on the piston to gradually urge the clutch plates together, thereby engaging the clutch.
