Abstract

A torque transmitting system for transmitting torque from a drive shaft of an engine to an output shaft without transmitting torque variation comprises a friction clutch unit interposed between these shafts, a fluid pressure-operated actuating unit for engaging and disengaging the friction clutch unit, operating condition detectors detecting the operation condition of the engine, and a rotation speed difference detector for detecting the rotation speed difference between the drive shaft and the output shaft. In the system, means are provided for setting the rotation speed difference between the shafts on the basis of the output signals from the operating condition detectors and for controlling the pressure of actuating fluid supplied to the fluid pressure-operated actuating unit so that the detected rotation speed difference approaches the pre-set rotation speed difference, whereby the torque can be transmitted from the drive shaft to the output shaft without any substantial variation.
