Abstract
A differential lock assembly includes a shift collar () that is moved in response to an electronic input signal between locked and unlocked positions. A coil housing () is supported on the shift collar and includes a recess () that receives a coil. A drag plate () is connected to the shift collar and coil housing to enclose the coil within the recess. When the coil is energized, the shift collar () is moved to the locked position. A resilient member () returns the shift collar () to the unlocked position when the coil is not energized. The shift collar (), coil housing (), drag plate (), and resilient member () are pre-assembled together to form an assembled unit, which is installed within an axle differential as an adjusting nut to apply preload to an associated differential bearing.
