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.

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 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.
