Abstract: Systems are provided herein for a multi-piece clutch gear assembly. In one example, a multi-piece clutch gear assembly comprises a helical gear and a clutch assembly, wherein the clutch assembly is coupled to and arranged within an interior of the helical gear, wherein the helical gear and the clutch assembly are formed as separate pieces and configured to be affixed together.

Abstract: Methods and systems for fabricating and operating a bi-stable solenoid actuator are described. The system may include permanent magnets that are arranged in a circle. The permanent magnets may provide sufficient force to maintain a differential in a locked state when electric power is not applied to a coil that operates as an electro-magnet.

Abstract: Methods and systems are provided for a vehicle including a first motor coupled to a first gear train, a second motor coupled to a second gear train, and a spool lock configured to variably couple the first gear train and the second gear train, allowing a first torque output by the first motor and a second torque output by the second motor to be combined and output to a first wheel coupled to the first gear train or a second wheel coupled to the second gear train.

Abstract: Methods and systems are provided for a disconnect device. In one example, a system for an electric drivetrain comprises a differential and a disconnect device arranged in a transmission housing and coupled to the differential, the disconnect device comprising a plurality of cam ring lugs engaged with a differential case, wherein each of the plurality of cam ring lugs is asymmetric.

Abstract: Methods and systems are provided for a disconnect assembly in an electric drive unit. In one example, the system includes a dog clutch positioned in a differential, configured to selectively mechanically decouple an electric motor from one or more drive wheels, and including a first interface designed to selectively engage a second interface. In such an example, each of the first interface and the second interface include a plurality of teeth, each tooth in the plurality of teeth includes a drive flank and a coast flank, and the coast flank has a first tooth angle greater than a second tooth angle of the drive flank.
