Patent number: 9764630Abstract: A hybrid drive of a motor vehicle has an internal combustion engine, an electric machine, an automated manual transmission with an input shaft and an output shaft, and a phase shifter gearbox in a planetary design with two input elements and one output element. A first input element of the gearbox is connected to a hollow shaft arranged in a coaxial manner around the output shaft, which is connectable to an idler gear of an axially adjacent spur gear stage of the manual transmission, and, for bypassing the gearbox, is connectable to the second input element or the output element of the gearbox. The second input element of the gearbox is permanently in drive connection with a rotor of the electric machine, and the output element of the gearbox is connected in a torque-proof manner to the output shaft.Type: GrantFiled: June 30, 2014Date of Patent: September 19, 2017Assignee: ZF Frierichshafen AGInventors: Johannes Kaltenbach, Michael Roske, Uwe Griesmeier

Patent number: 9731588Abstract: A hybrid drive of a motor vehicle has an internal combustion engine, an electric machine, and a transmission. The transmission is a multi-stage shifting transmission including two subtransmissions, each of which has a separate input shaft and a common output shaft. The first input shaft of a first subtransmission can be coupled to the internal combustion engine via a friction-locking clutch in such a way that when the clutch is engaged the internal combustion engine is coupled to the first input shaft and thus to the first subtransmission, and when the clutch is disengaged the internal combustion engine is decoupled from the first input shaft and thus decoupled from the first subtransmission. A second input shaft of a second subtransmission is rigidly coupled to the electric machine, and both input shafts can be coupled selectively to the common output shaft via form-locking shift elements of the subtransmissions.Type: GrantFiled: November 5, 2012Date of Patent: August 15, 2017Assignee: ZF Friedrichshafen AGInventors: Johannes Kaltenbach, Uwe Griesmeier
