ABSTRACT:
A device for transmitting torque between two rotatable shaft members (2, 3) in a stationary housing (1) contains a number of alternate clutch discs (10, 11) engageable to counteract differential rotational speed between the two shaft members, to which they are connected, a hydraulic clutch piston (12) to engage the clutch discs and a hydraulic pump arrangement (15-24) driven by the speed differential between the two shaft members. An annular control piston (15) is axially movably arranged in the housing and is in contact with control pins (17), which are rotatable together with one of the shaft members (3) and cooperate with a cam curve (20) in the other shaft member (2) in such a way that the control pins and thus the control piston are imparted an oscillating movement with a frequency directly proportional to the rotational speed differential between the two shaft members.
