Device for the transmission of torque from a reciprocating piston engine to a gearbox

摘要

For vibration-damped transmission of torque from the crankshaft of a reciprocating piston engine to the input shaft of a motor-vehicle gearbox, a hydraulically operated friction clutch is arranged between the two shafts. A friction disc of the friction clutch and an oil pump are driven simultaneously by the input shaft. The oil pump delivers an oil pressure which rises progressively with the difference between the speeds of the input shaft and the crankshaft, the pressure being transmitted to the friction disc via an annular piston and producing a corresponding contact force on the said friction disc.
