Slip control system for a clutch
First Claim
1. A torque transmitting system comprising a drive shaft rotating with torsional vibration, an output shaft, a friction clutch unit interposed between said drive shaft and said output shaft, fluid pressure-operated actuating means for causing engagement and disengagement of said friction clutch unit, means for detecting the operating condition of a drive power source driving said drive shaft, means for detecting the difference between the rotation speed of said drive shaft and that of said output shaft, means for setting the rotation speed difference between said drive shaft and said output shaft in response to the output signal from said operating condition detecting means, and fluid pressure control means for controlling the pressure of actuating fluid supplied to said fluid pressure-operated actuating means so that the rotation speed difference detected by said rotation speed difference detecting means approaches the rotation speed difference set by said rotation speed difference setting means.

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.
