摘要： An electric powertrain includes a first electric motor that has an uninterrupted connection with a drive shaft of a vehicle. The electric powertrain further includes a second electric motor that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a clutch. The electric powertrain further includes a first gear train in the form of a first planetary gear and a second gear train in the form of a second planetary gear.

摘要： Methods and systems for an electric drive axle of a vehicle are provided. An electric drive axle system includes, in one example, an electric motor-generator rotationally coupled to a gear train. The gear train includes an output shaft rotationally coupled to a gear assembly axially offset from an input shaft rotationally coupled to the electric motor-generator, where the gear assembly is rotationally coupled to a differential and the differential is rotationally coupled to an axle, a first clutch assembly is configured to rotationally couple and decouple a first gear set from the output shaft, and a second clutch assembly is configured to rotationally couple and decouple a second gear set from the output shaft, the second gear set having a different gear ratio than the first gear set.

摘要： A clutch assembly includes a clutch housing, a clutch hub, a clutch pack and an oil deflector. The clutch pack includes at least one friction plate connected to one of the clutch housing and the clutch hub and at least one separator plate connected to the other of the clutch housing and the clutch hub. The oil deflector includes a circumferential wall and a flange. The circumferential wall includes a drain slot. The flange extends radially outwardly from an end of the circumferential wall and is mounted to one of the at least one separator plate and the at least one friction plate. The circumferential wall and the first flange cooperate to define a channel. Lubricant flowing along the clutch housing flows to the channel where the lubricant is directed away from the clutch pack and out of the drain slot.

摘要： A hybrid module housing includes a bulkhead. The bulkhead has a first radial channel for providing a clutch apply pressure, a second radial channel for providing a clutch cooling flow, and a third radial channel for providing a motor cooling flow. In an example embodiment, the third radial channel is arranged to be on a bottom half of the hybrid module housing when the hybrid module housing is installed in a vehicle. In an example embodiment, the first radial channel and the second radial channel are open at a radially outer surface of the bulkhead, and the third radial channel is sealed at the radially outer surface of the bulkhead. In an example embodiment, the third radial channel includes an axial passage open at a radial wall of the bulkhead.
