Abstract: Methods and systems for an electric drive assembly are provided herein. In one example, an electric drive system is provided that includes two multi-motor drive units with associated planetary gear reductions that have asymmetric gear ratios. The planetary gear reduction in each drive unit includes a ring gear and a sun gear that are rotationally coupled to a pair of motors and a carrier rotationally coupled to an output gear that interfaces with a gear reduction of an axle assembly.

Abstract: Various methods and systems are provided for a shift assembly for a vehicle transmission. In one example, a shift assembly for a transmission includes a first barrel cam including a first cam track; a second barrel cam arranged coaxially with the first barrel cam and including a second cam track; a first motor configured to drive the first barrel cam independent of the second barrel cam; and a second motor configured to drive the second barrel cam independent of the first barrel cam.

Abstract: Various methods and systems are provided for an dual-faced clutch collar for a transmission. In one example, a dual-faced clutch collar positioned on an output shaft of a gearbox comprises a clutch collar spline, where the clutch collar spline mates with the output shaft; a first face having a first set of axially protruding teeth to engage a high torque coupling, the first set of teeth having a first profile; and a second face having a second set of axially protruding teeth to engage a low torque coupling; the second set of teeth having a second profile; the second profile being different from the first profile. The first profile may be a courser tooth profile, to allow for maximum load carrying capacity, and the second profile may be a finer tooth profile, to allow for quicker gear engagements and more neutral space (e.g., due to reduced tooth depths).

Abstract: A cooling system for an electric machine is provided that includes a housing at least partially enclosing a rotor, a stator, and a coolant jacket, the coolant jacket including a plurality of coolant channels that receive coolant from a coolant inlet. In the cooling system two or more materials that form boundaries of the plurality of coolant channels are configured to thermally expand at different rates and form a bypass flow passage of at least one of the plurality of coolant channels when the two or more materials are below a threshold temperature or within a lower temperature range.

Abstract: Methods and systems for evacuating lubricant from an area of an axle are described. The lubricant may be evacuated away from one or more clutches during low temperatures so that a clutch may be engaged while having to displace less lubricant to engage the clutch. In one example, an electric machine may be rotated to evacuate lubricant away from the clutch.

Abstract: A method and system for shifting a transmission that includes one or more mechanical clutches without clutch plates is described. In one example, a torque output of an electric machine is adjusted in response to a request to shift a transmission so that forces that hold the mechanical clutch in an engaged position may be reduced.

Abstract: Methods and systems for an electric motor system are provided. In one example, a motor system is provided which comprises a first electric machine rotationally coupled to a second electric machine by a planetary gear set that has three components: a ring gear, a sun gear, and a carrier with a plurality of planet gears. In the system, the first electric machine varies in size from the second electric machine and one of the planetary assembly components is permanently grounded.
