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 a flow guide element, which is supported between the hub and the drive-side housing wall, and has first and second flow passages which are axially offset from each other. The flow guide element 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.
