ABSTRACT:
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.
