Date Sep. 26, 1985.A fluid friction clutch for use in differential gears of motor vehicles having a sliding member which has a adjusting disc which changes the spacing of the clutch plates, which adjusting causes the clutch plates to approach closer to one another and increases the clutch torque provided by a viscuous fluid of the fluid of the clutch. Adjustment takes place via starting slopes which are assigned to a cam driving connection employing a special development of the starting slopes with the torque characteristics being changed in a predetermined manner.
