Patent number: 10350985Abstract: A drive train of a hybrid motor vehicle has an internal combustion engine (4), at least one first electric motor (16), at least a first clutch arrangement (6), at least one gear assembly (8), a storage arrangement and at least one auxiliary unit, such as an air conditioning compressor. The internal combustion engine (4) is connected drivingly to a first drive axle (14) via the clutch arrangement (6) and the gear assembly (8), and the first electric motor (16) is connected drivingly to a second drive axle (22) and to the storage arrangement and/or the auxiliary unit. The first electric motor (16) has a rotor shaft (36) with a first end (34) drivingly connected to the second drive axle (22) by a first switching unit (18) and a second end (38) drivingly connected to a crankshaft (28) of the internal combustion engine (4) by a second switching unit (24).Type: GrantFiled: June 24, 2014Date of Patent: July 16, 2019Assignee: Dr. Ing. h.c. F. Porsche AktiengesellschaftInventor: Falk Heilfort

Patent number: 10234011Abstract: A spur gear for transmitting a drive torque in a toothing of a motor vehicle transmission is provided, having a helically toothed first gear body for forming first teeth, a second gear body, which is helically toothed oppositely to the first gear body so as to form a herringbone toothing, for forming second teeth, wherein, on axial sides which face toward one another of the first gear body and of the second gear body, the first teeth and the second teeth point toward one another, so as to at least partially overlap one another, in each case pairwise, wherein, on that axial side of the first gear body which points toward the second gear body, a first tooth flank of the first tooth points in an axial direction toward a second tooth flank of a second tooth which follows the opposite second tooth in a circumferential direction.Type: GrantFiled: June 15, 2016Date of Patent: March 19, 2019Assignee: Dr. Ing. h.c. F. Porsche AktiengesellschaftInventors: Peter Meffert, Falk Heilfort

Patent number: 9625021Abstract: An electric portal axle (1) for electrically driving a motor vehicle has a housing (28), a single electric machine (2) and two spur gear stages (13, 14) for driving two wheels of the axle. A shiftable transmission (5) is downstream of the electric machine (2) and is embodied as a planetary gear mechanism with a freewheel (6) and a differential (7). The portal axle (1) has a shifting mechanism (23) for shifting two gear stages of the portal axle (1). In a first gear stage, a ring gear (9) of the transmission (5) and a clutch body (27) that is fixed to the housing are connected, and a clutch (29) between the ring gear (9) and a planetary carrier (11) of the transmission (5) is opened. In a second gear stage the ring gear (9) and the clutch body (27) are disconnected and the clutch (29) is closed.Type: GrantFiled: February 9, 2015Date of Patent: April 18, 2017Assignee: Dr. Ing. h.c.
