Patent ID: 7455159

Claim:
A torque transmitting unit for a motor vehicle power train for transmitting torque between an engine having an output shaft and a transmission having at least one transmission input shaft, said torque transmitting unit comprising: a friction clutch operatively connected between the engine output shaft and the at least one transmission input shaft, the clutch including a plurality of alternating frictional components stacked in an axial direction; an operating member arranged to transmit an axial force to press the frictional components together; an actuator for applying an axial force to the operating member and connected to a fixed housing part in a rotationally fixed connection; an operating bearing positioned between the actuator and the operating member to permit rotation of the operating member relative to the actuator; wherein the friction clutch is operated as a wet mode clutch for cooling the clutch; and a pump indirectly rotatably coupled with the engine output shaft for providing cooling oil to the clutch, wherein a rotatable coupling drive for rotating the pump is arranged concentrically with the at least one transmission shaft, and the pump has an axis of rotation that is radially offset from the axis of rotation of the at least one transmission input shaft.
