A torsional vibration damping disk having receiving spaces for spring elements, particularly for bow spring elements, which are each arranged between two limit stop areas in the peripheral direction. In order to create a torsional vibration damping disk, which is producible easily and cost-effectively, the spring elements are each clamped with a slight pretension between two limit stop areas.

An assembly for improving a connection between splined assemblies generally includes first and second assemblies each having at least one spline thereon, an integral fastening assembly for axially fastening the first assembly with respect to the second assembly, and a biasing assembly for asserting a force to oppositely rotationally dispose the first and second assemblies with respect to one another. In an embodiment, the first and second assemblies are annular plates. A method for improving a connection between splined assemblies generally includes asserting a bias upon first and second assemblies such that are oppositely rotationally disposed with respect to one another. In the above method, the first assembly and the second assembly each have at least one spline, an integral fastening assembly for axially securing the first and second assemblies, and a biasing assembly. In an embodiment of the above method, the first and second assemblies are annular plates.

A dual automatic mechanically actuated wet clutch device, for operation within a fluid tight housing, for a dual input shaft transmission that includes tightly specified average spacing between friction plate surfaces where the average spacing is selected from between about 0. 05 mm to about 0. 25 mm in an open position. The clutch has at least first and second independently actuatable clutch portions, and at least one clutch pack in the first or second clutch portion; and mechanical apparatus provided to move friction plates in at least one of the clutch portions toward each other so that they engage. The invention also includes apparatus and methods for adjusting and maintaining the spacing between the friction plate surfaces.

The present invention broadly comprises a ring carrier with a wall arranged to engage at least a portion of an outer circumference of a clutch pack for a clutch assembly for a vehicle and a clutch housing with a wall arranged to engage at least a portion of an inner circumference of the clutch pack. The wall for the housing includes at least one opening and the clutch housing is arranged to pump fluid through the opening in the wall independent of the rotation of an output hub for the carrier. The clutch housing can be configured as an inner clutch housing. The clutch housing includes a connecter portion arranged to transfer engine torque to the cylindrical wall from an outer housing of the clutch assembly connected to an engine crankshaft. The present invention also includes a clutch assembly with the ring carrier and clutch housing.

A torque converter including a damper assembly connected to a hub for the torque converter; a turbine clutch connected to a turbine and the damper assembly; and a torque converter clutch connected to a cover for the torque converter and the damper assembly. In an idle mode, the turbine clutch and the torque converter clutch are disengaged and the torque converter cover is rotationally disconnected from the hub. In a torque converter mode, the turbine clutch is engaged, the torque converter clutch is disengaged, and the turbine clutch rotationally locks the turbine and the damper assembly. In a lock-up mode, the torque converter clutch is engaged and the torque converter clutch rotationally connects the torque converter cover and the damper assembly.

A multi-function torque converter including: an apply pressure chamber for a torque converter clutch; a first pressure chamber including a torus; and a resilient flow control element in fluid communication with the apply chamber and the first pressure chamber and arranged to control fluid flow to the apply pressure chamber. The resilient flow element is displaceable to block fluid flow to the apply pressure chamber in torque converter mode for the torque converter and to enable fluid flow to the apply chamber in lock-up mode. The torque converter includes a second pressure chamber and the clutch includes a piston plate at least partially bounding the apply pressure chamber and the second pressure chamber.
