A wet clutch arrangement, particularly a wet plate clutch or lockup clutch including a first friction face formation coupled with a housing arrangement for rotation around an axis of rotation and a second friction face formation coupled with an output member for rotation around the axis of rotation, and a preferably ring-shaped pressing piston. The pressing piston, together with the housing arrangement, defines a pressure fluid space and is movable in direction of the axis of rotation through a change in fluid pressure in the pressure fluid space for influencing the frictional interaction between the friction face formations. An operant fluid application surface of the pressing piston is in the range of 15000 mmto 25000 mmfor generating a force acting upon the pressing piston.

Wet-running clutch arrangement

A bridging clutch is installed in a fluid medium-filled housing of a hydrodynamic coupling device located between a drive shaft and a transmission input shaft, the coupling device also containing a pump wheel and a turbine wheel. The bridging clutch is provided with a piston, which, when moved into a first axial position, brings at least one friction element into working connection with at least one friction surface, and when moved into a second axial position, at least partially releases this working connection, and with a torsional vibration damper, which is designed with at least one drive element and with at least one takeoff element, at least one of which has openings for circumferential springs and actuating areas for these springs. At least one of the takeoff elements acts a carrier element for the turbine wheel, which is held otherwise without radial support in the housing. At least one of these elements, namely, either the drive element or the takeoff element, has at least one radial area which is brought up in the axial direction essentially without play to the other one of the elements in question, which radial area serves as axial support for the positioning of the turbine wheel in this direction with respect to the housing of the coupling device.

Bridging clutch

A hydrodynamic clutch device for a hydrodynamic torque converter includes a turbine wheel for rotation about an axis of rotation. The turbine wheel is connected by a lockup clutch arrangement for transmitting torque to a housing arrangement. The turbine wheel includes a turbine wheel shell for housing turbine wheel blades. The turbine wheel shell is operably connected by a torsional vibration damper arrangement for transmitting torque. The torsional vibration damper arrangement includes a first transmission element coupled with the lockup clutch arrangement and the turbine wheel shell and includes a second transmission element coupled with the first transmission element for transmitting torque by means of a damper element arrangement; and wherein the first transmission element is supported at the housing arrangement in a first direction by a bearing arrangement.
