Patent number: 8757305Abstract: A hybrid drive arrangement for a vehicle with an internal combustion engine for driving, under engine power, and at least one electric machine (1), for electric driving, and with a double-clutch transmission. The electric machine (1) can be separated from the internal combustion engine by at least one separator clutch (3), in the form of a wet-operating, hydraulically actuated disk clutch. The outer disk carrier (4) of the separator clutch (3) and the outer disk carriers (5, 5A) of the two double clutches, of the double-clutch transmission, are connected and mounted on the transmission housing (6).Type: GrantFiled: March 17, 2011Date of Patent: June 24, 2014Assignees: ZF Friedrichshafen AG, Dr. Ing. h.c.F.

Publication number: 20080113846Abstract: A combination drive unit including an internal combustion engine and an electric machine, where the internal combustion engine includes a housing with a crankshaft supported therein; where the electric machine includes a rotor with a rotor shaft, the rotor being supported rotatably on a stationary component, and a stator, which is mounted radially with respect to the rotor. The crankshaft is in working connection with the rotor shaft at least indirectly and at least temporarily by way of a coupling. For the event that the crankshaft and the rotor shaft are offset from each other, the unit has separate first and second compensating devices, so that the wobbling forces which occur during operation of the unit can be absorbed.Type: ApplicationFiled: November 13, 2007Publication date: May 15, 2008Applicant: ZF Friedrichshafen AGInventors: Peter Wiggen, Bernd Peinemann, Olaf Pagels, Manfred Zimmer, Christoph Kleuker, Udo Niehaus, Michael Kuhner, Steffen Matschas, Alexander Bartha
