ABSTRACT:
The object of the invention is to provide an automatic clutch control system for coupling two rotating shafts. The system comprises a piston axially movable towards an engaged position to provide the axial clamping of at least one friction disc forming part of a hydraulically controlled clutch mounted between two shafts. A control member responsive to the difference in speed between the shafts moves the piston towards its engaged position and is advantageously constituted by a lobed pump having a central pinion, an inner crown, eccentric relative to the pinion, and an outer crown centered relative to the pinion. The pinion is fixed for rotation on one of the shafts while the outer crown is integral in rotation with the other of the shafts.
