Methods and systems are provided for selectively engaging an electric machine to an electric axle of a vehicle. In one example, a method may include engaging or disengaging the electric machine to a differential of the electric-axle by adjusting pressure in a piston coupled to an axle shaft of the electric-axle via a disconnect clutch.

System and method for a differential disconnect electric axle

Methods and systems for a locking mechanism in an inter-axle differential are provided. A vehicle system, in one example, includes an electric motor coupled to a clutch assembly in a locking mechanism of an inter-axle differential coupled to a first axle and a second axle, the clutch assembly is configured to selectively disengage the locking mechanism, and in the disengaged configuration the locking mechanism permits speed differentiation between the first and second axles. The system further includes an electric motor brake coupled to the electric motor and configured to selectively apply a brake torque to the electric motor and the electric motor is configured to actuate the clutch assembly.

Inter-axle differential and method for operation of said inter-axle differential

A drive unit assembly having a shroud for use in a vehicle. The drive unit assembly includes a ring gear having an outermost surface, an innermost surface, a first side and a second side. A plurality of ring gear teeth circumferentially extend from at least a portion of the second side of the ring gear of the drive unit assembly. The shroud of the drive unit assembly includes a first shroud member that is integrally connected to at least a portion of a second shroud member. At least a portion of the ring gear is disposed within at least a portion of the shroud of the drive unit assembly.

Lubricant fluid shroud

An axle assembly includes a carrier housing, a ring gear disposed within the carrier housing, and a pinion meshed with the ring gear. The pinion is coupled with a pinion shaft rotatably supported in the carrier housing by at least one bearing. A sump and a fluid catch are disposed in the carrier housing. A conduit having a regulator is in fluid communication with the fluid catch and the at least one bearing.

Lubricant flow regulating system and the axle assembly made therewith

A tandem axle system has a forward axle system and a rear axle system. A method of selectively driving one or both of the axle systems is described.
