ABSTRACT:
A hydrodynamic clutch includes a hydrodynamic circuit formed by at least a pump wheel and a turbine wheel in a clutch housing with a drive-side housing wall extending to the axis of rotation, and a bridging clutch with a piston capable of shifting axially relative to the drive-side housing wall. The turbine wheel is connected to a hub, which is connected for rotation in common to a takeoff, and is axially supported between the hydrodynamic circuit and the clutch housing, and has first and second flow passages which are axially offset from each other. The hub has a drive-side end with an axial bearing area which can be moved into axial contact with an axial bearing, which is either an axial contact surface on the drive-side housing wall or is assigned to the drive-side housing wall.
