An assembly of a crown wheel and a differential casing of a differential gear assembly is adapted to welding. The differential casing has a circular flange with an axially extending lip engaged in a circular groove of the crown wheel, which is further relieved at a radially outer side to give clearance for a high energy welding beam. An interface between the crown wheel and the circular flange is in one example a frusto-conical surface, which presents an oblique angle to the welding beam.
A differential gear casing of flower pot construction has an outer surface which is configured for receiving a crown wheel, whereby the crown wheel can be pressed onto the outer surface by different amounts for different applications. The outer surface is free from projections such that the crown wheel can be mounted on the outer surface from any axial direction. The outer surface defines a band on the differential gear casing and is parallel with a central axis of the differential gear casing. The crown wheel is secured to the differential gear casing using an axial weld line. In other embodiments, the crown wheel and/or a cover for the differential gear casing are secured in place using axial and/or radial weld lines.

An electronic differential lock assembly includes a shift collar that is movable in response to an electronic signal from an unlocked position where axle shaft speed differentiation under predetermined conditions is permitted to a locked position where a pair of axle shafts is fixed for rotation together. Speed differentiation is provided by a differential that includes a differential gear assembly supported within a differential case. A coil surrounds the shift collar and is selectively energized to move the shift collar from the unlocked position to the locked position. The shift collar is splined to one of the axle shafts and is selectively splined to the differential case to lock the axle shafts together. The electronic differential lock assembly includes a return spring that automatically disengages the shift collar from the differential case once the coil is no longer energized.
