Patent number: 9140348Abstract: A hydrodynamic coupling includes a housing coupled to a driveshaft having an impeller and a turbine wheel arranged in the housing driven by the impeller and a first damper arrangement by which the housing is coupled to a driven member by a lockup clutch. The first damper arrangement includes a first torsional vibration damper connected to the lockup clutch that is rotatable around an axis of rotation against the action of a first damper spring arrangement. A second torsional vibration damper is connected to the first torsional vibration damper and rotatable around the axis of rotation against the action of a second damper spring arrangement. The turbine wheel is connected to an intermediate torsional vibration damper region including a first secondary side, a second primary side, a second damper arrangement has a deflection mass carrier connected to the second secondary side.Type: GrantFiled: December 7, 2009Date of Patent: September 22, 2015Assignee: ZF Friedrichshafen AGInventors: Michael Heuler, Patrick Rediger, Mario Kensy, Alexander Strom

Patent number: 8042666Abstract: 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.Type: GrantFiled: March 26, 2008Date of Patent: October 25, 2011Assignee: ZF Friedrichshafen AGInventors: Peter Frey, Roland Baumann, Michael Greulich, Georg Mencher, Bernd Reinhardt, Peter Hammer, Patrick Rediger

Patent number: 7984800Abstract: 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.Type: GrantFiled: March 26, 2008Date of Patent: July 26, 2011Assignee: ZF Friedrichshafen AGInventors: Peter Frey, Roland Baumann, Michael Greulich, Georg Mencher, Bernd Reinhardt, Peter Hammer, Patrick Rediger
