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

An actuation assembly for use in a drive unit assembly of a vehicle. The actuation assembly includes an actuator shaft that is connected to a shift shaft and a shift fork via a lever member. At least a portion of the lever member is connected to the shift shaft and at least a portion of the lever member is pivotably connected to said actuator shaft. An actuation mechanism drives the actuator shaft linearly to pivot the lever member which in turn rotates the shift shaft and the shift fork.

Shift fork actuation assembly

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

An oil feed channel lubricating system including a first upstanding wall, a floor and a portion of an interior wall of a carrier. The channel has a first portion angled at a first angle and a second portion angled at a second angle. The first portion preferably has a shallower angle than the second portion. A gap is located between a top of the first upstanding wall and the interior wall of the carrier.
