ABSTRACT:
A friction clutch for use in a gear changing transmission for facilitating a power transmission from a rotating shaft of a working exhaust-gas turbine onto a crankshaft of an internal combustion engine, which friction clutch, depending on the engine and/or turbine speed, automatically closes in the direction of engagement and opens in the direction of disengagement, with the friction members of the clutch being able to be compressed in the direction of engagement against a spring force (cup springs) by a piston of a rotating cylinder-piston-unit provided on the drive side of the clutch, such that a fluid conveyed from an external pump into the cylinder applies a fluid pressure onto the piston in response to rotation (centrifugal force). The engine lubricant is preferably used as the fluid.
