Patent ID: 7984800

Claim:
A hydrodynamic clutch device comprising: a clutch housing that is rotatable about an axis of rotation and has a drive-side housing wall that extends radially inward at least essentially as far as said axis; a hydrodynamic circuit comprising a pump wheel and a turbine wheel in said clutch housing; a bridging clutch having a piston capable of shifting axially relative to said drive-side housing wall, the piston separating a pressure space adjacent to the drive-side housing wall from a supply space; a hub that is supported axially between the hydrodynamic circuit and the drive-side housing wall, the hub being connected for rotation in common to a take-off; a flow guide element supported axially between the hub the drive-side housing wall, the flow guide element having at least one of first and second flow passages connecting a respective at least one of first and second take-off side flow channels to a respective at least one of the pressure space and the supply space, and a drive-side end with an axial bearing area; a contact surface between the drive-side housing wall and the axial bearing area; and a rotation lock connecting the flow guide element to the hub for rotation in common; and the rotation lock connecting the drive-side housing wall to the flow guide element, wherein the rotation lock comprises a first set of teeth on the flow guide element facing the hub, and a second set of teeth on the hub facing the flow guide element, the first set of teeth mating with the second set of teeth.
