Abstract:
1. A device for transmitting torque between two rotatable coaxial shaft members, the device comprising a plurality of alternate clutch discs connected to the two shaft members and engageable to counteract differential rotational speed between the shaft members, braking means for braking rotational movement wherein rotational velocity in the braking means is proportional to said differential rotational speed, and means for transmitting said differential rotational speed to the braking means comprising a roller arrangement; wherein the roller arrangement comprises a cylindrical roller cage with two sets of rollers; wherein a first set of said two sets of rollers is mounted for rolling in an outer ring and a second set of said two sets of rollers is mounted in a gear ring; and wherein the rollers of said first set and said second set are radially prestressed by the outer ring and the gear ring respectively.
