Abstract

A device for transmitting torque between two rotatable, coaxial shaft members (1, 2) contains a number of alternate clutch discs (5, 6) for counteracting differential rotational speed between the two shaft members. Planetary gear means (11, 15, 16-20) are connected to the first shaft means (1). A pressure plate (7) is connected to the second shaft member (2) and is axially displaceable against the clutch discs (5, 6) for their engagement. Transmission means in the form of rollers (10) are arranged between the gear means and the pressure plate for axially displacing the pressure plate against the clutch discs at a certain rotation differential between the gear means and the pressure plate. Electrical braking means (21-24) connected to the gear means can provide a force to the transmission means for its axial displacement.
