Patent ID: 8893867

Claim:
A wet clutch arrangement, comprising: a housing arrangement that is at least one of filled with a fluid and fillable with the fluid; a friction coupling region having: a first friction surface formation configured to rotate with the housing arrangement around an axis of rotation; and a second friction surface formation configured to rotate with a driven element around the axis of rotation that can be brought into frictional engagement with the first friction surface formation; a fluid coupling region that defines a toroidal fluid circulation space having: an impeller configured to rotate with the housing arrangement around the axis of rotation; and a turbine configured to rotate with the driven element around the axis of rotation and which, along with the impeller, wherein the fluid coupling region is arranged radially outside the friction coupling region; and a torsional vibration damper arrangement having a first torsional vibration damper region and a second torsional vibration damper region arranged in series with the first torsional vibration damper region, wherein the torsional vibration damper is configured to couple at least one of the turbine and the second friction surface formation to the driven element, and wherein the turbine is connected to at least one of an output region of the first torsional vibration damper region and an input region of the second torsional vibration damper region.
