Publication number: 20200247229Abstract: A hybrid drive module (1) for a motor vehicle includes a housing (GG), a torque converter (TC), and an electric machine with a rotor (R) and a stator (S). The rotor (R) is arranged on a rotor carrier (RT), which is fixedly connected to a hub (N). The hub (N) is rotatably supported via at least one first bearing (L1) and is supported in radial and axial directions against a bearing shield (LS). The hub (N) is rotationally fixed to a converter housing (TCH) of the torque converter (TC) via a rivet joint (RI) or a screw connection. A drive train for a motor vehicle including such a hybrid drive module (1) is also provided.Type: ApplicationFiled: September 6, 2018Publication date: August 6, 2020Inventors: Thomas Riedisser, Robert Reiser, Gerald Viernekes, Jürgen Dacho, Thomas Bauer, Monika Rössner, Stephan Stroph, Linus Eschenbeck, Christopher Allnoch, Erwin Wack, Mario Kensy, Peter Frey, Christian Wickel, Michael Wirachowski

Patent number: 8387766Abstract: A wet clutch arrangement, particularly a wet plate clutch or lockup clutch including a first friction face formation coupled with a housing arrangement for rotation around an axis of rotation and a second friction face formation coupled with an output member for rotation around the axis of rotation, and a preferably ring-shaped pressing piston. The pressing piston, together with the housing arrangement, defines a pressure fluid space and is movable in direction of the axis of rotation through a change in fluid pressure in the pressure fluid space for influencing the frictional interaction between the friction face formations. An operant fluid application surface of the pressing piston is in the range of 15000 mm2 to 25000 mm2 for generating a force acting upon the pressing piston.Type: GrantFiled: October 16, 2009Date of Patent: March 5, 2013Assignee: ZF Friedrichshafen AGInventors: Gregor Sueck, Jürgen Dacho, Thomas Adelmann

Publication number: 20100294610Abstract: A fluid-filled clutch arrangement includes a housing; a piston mounted with freedom of axial movement in the housing, the piston being sealed against the housing, the piston having a drive side bounding a drive side pressure space from a takeoff side bounding a takeoff side pressure space; a clutch which can establish and release a working connection between a drive and a takeoff as a function of the position of the piston relative to the clutch; and a partition wall bounding the takeoff side pressure space opposite the piston, the partition wall being active between the takeoff side pressure space and a cooling space. At least one supply line connects a fluid supply source to at least one of the drive-side pressure space, the takeoff side pressure space, and the cooling space.Type: ApplicationFiled: May 24, 2010Publication date: November 25, 2010Inventors: Michael Heuler, Jürgen Dacho

Patent number: 6915886Abstract: 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.Type: GrantFiled: September 11, 2003Date of Patent: July 12, 2005Assignee: ZF Sachs AGInventors: Jürgen Dacho, Peter Frey, Ralf Rönnebeck, Georg Mencher, Bernd Schöder, Horst Breier, Hermann Schleicher

Patent number: 6837348Abstract: A hydrodynamic clutch device for a hydrodynamic torque converter includes a turbine wheel for rotation about an axis of rotation. The turbine wheel is connected by a lockup clutch arrangement for transmitting torque to a housing arrangement. The turbine wheel includes a turbine wheel shell for housing turbine wheel blades. The turbine wheel shell is operably connected by a torsional vibration damper arrangement for transmitting torque. The torsional vibration damper arrangement includes a first transmission element coupled with the lockup clutch arrangement and the turbine wheel shell and includes a second transmission element coupled with the first transmission element for transmitting torque by means of a damper element arrangement; and wherein the first transmission element is supported at the housing arrangement in a first direction by a bearing arrangement.Type: GrantFiled: March 5, 2003Date of Patent: January 4, 2005Assignee: ZF Sachs AGInventors: Horst Breier, Georg Mencher, Thomas Bauer, Ralf Rönnebeck, Jürgen Dacho, Peter Frey, Bernd Schöder
