Abstract
A coupling device for transmitting torque between a first part and a second part which are rotatable relative to one another is disclosed. The coupling device comprises a multi-plate coupling unit with axially alternating arranged first plates and second plates. The first plates are each connected in a rotationally fixed manner to one of the first part or the second part and the second plates are each connected in a rotationally fixed manner to the other of the first part or the second part. The coupling device further comprises an actuating assembly for axially loading the multi-plate coupling unit by means of a setting piston. The multi-plate coupling unit also comprises a first annular chamber filled with a highly viscous fluid and delimited by the setting piston, and a rotational member arranged in the annular chamber. The first annular chamber is formed in one of the first or second parts with the rotational member being connected in a rotationally fixed manner to the other of the first or second part. A relative rotation between the first and second parts causes pressure-loading and displacement of the setting piston towards the multi-plate coupling unit as a result of the sh…
