Patent number: 11560017Abstract: An axle assembly for a vehicle. A movable housing is movably positioned within a closed channel defined by a central housing. The movable housing moves the axle assembly between a retracted configuration and an extended configuration. A mounting assembly may be coupled to and spaced from the movable housing and slidably positioned adjacent the central housing. A steering actuator is coupled to a steering arm and the mounting assembly such that the steering actuator moves as a unit. A track assist bracket may be fixedly coupled to the central housing and define a gap sized to slidably receive a mounting plate of the mounting assembly. A bushing may be disposed on each wall of a telescoping portion of the movable housing. A bellows may be provided to enclose exposed portions of the bushings in the extended configuration. Methods of adjusting the track of the axle assembly are also disclosed.Type: GrantFiled: July 12, 2018Date of Patent: January 24, 2023Assignee: AxleTech International IP Holdings, LLCInventors: Amy Danielle Langlitz, Christopher G.
