Patent number: 7264100Abstract: A dual clutch assembly includes a torsional vibration damper and a dual clutch. The vibration damper has a primary side which can be coupled to a driving member for joint rotation about an axis, a secondary side which is rotatable about the axis, and a damper element arrangement between the primary side and the secondary side. The dual clutch includes an input area and two output areas, the input area supporting the secondary side of the torsional vibration damper in at least one of an axial and radial direction with respect to the primary side, each output area being coupleable with a respective driven member so as to be fixed against rotation with respect to the driven member. A bearing arrangement supports the input area in at least one of an axial and a radial direction with respect to a stationary subassembly.Type: GrantFiled: November 18, 2003Date of Patent: September 4, 2007Assignee: ZF Friedrichshafen AGInventors: Reinhard Feldhaus, Markus Heiartz, Igor Kister, Thomas Dögel, Sebastian Vogt

Patent number: 6814204Abstract: A crankshaft 2 of an internal combustion engine, which is supported with freedom to rotate around an axis of rotation 3, can be connected by a first clutch 1 to a flywheel 4, which is also supported with freedom to rotate around the axis of rotation 3. In addition, the flywheel 4 can be connected by a second clutch 5 to a transmission shaft 6, also supported with freedom to rotate around the axis of rotation 3. The flywheel 4 is provided with at least one permanent magnet and thus forms the rotor 8 of a crankshaft starter-generator. The pole fields of the permanent magnets can be moved past the stator coil of a stator 9 of the crankshaft starter-generator, this coil being mounted on a stationary component. Each of the first and the second clutches 1, 5 has its own separately operated actuating means and can be engaged and disengaged either independently of each other or in common.Type: GrantFiled: February 12, 2003Date of Patent: November 9, 2004Assignee: ZF Sachs AGInventors: Matthias Diemer, Christoph Kleuker, Markus Heiartz

Patent number: 6814197Abstract: An actuating device for a friction clutch device installed in the drive train of a motor vehicle introduces actuating forces, especially clutch-engaging or clutch-releasing forces, to the friction clutch device to actuate at least one friction clutch of the friction clutch device in the engaging or releasing direction. At least one actuating element assigned to a friction clutch can be shifted axially relative to at least one support element, which is essentially fixed in the axial direction, to exert the actuating forces. The actuating element belongs to an actuator assigned to the clutch or can be shifted axially relative to the support element by the intermediate action of an actuator assigned to the clutch.Type: GrantFiled: October 8, 2002Date of Patent: November 9, 2004Assignee: ZF Sachs AGInventors: Markus Heiartz, Andreas Orlamünder, Sebastian Vogt, Olaf Pagels, Georg Zink, Christoph Kleuker
