  • Electronic locking differential with direct locking state detection system
    Patent number: 7942780
    Abstract: An axle assembly with an electronic locking differential that employs a locking mechanism having components that are fixed to one another along an axis such that they co-translate with one another when the actuator that effects the locking and unlocking of the differential is operated.
    Type: Grant
    Filed: June 29, 2010
    Date of Patent: May 17, 2011
    Assignee: American Axle & Manufacturing, Inc.
    Inventors: Gregory M. Donofrio, Jeffrey A. Goolsby

  • Electronically actuated apparatus using solenoid actuator with integrated sensor
    Patent number: 7682279
    Abstract: A locking differential assembly with a differential case, a gearset, a first dog, a second dog and a thrust member. The differential case has a mounting hub. The gearset is disposed in the differential case and has a side gear. The first dog is coupled to the side gear. The thrust member is slidably supported on the mounting hub and has projections that extend through apertures in the differential case and engage the second dog.

  • Locking differential assembly
    Patent number: 7534187
    Abstract: An axle assembly with an electric locking differential that can include a one-piece differential case and a locking device. The locking device includes a dog that is nonrotatably but axially slidably received into a pocket that is formed in an end of the differential case. An actuator is mounted on the differential case. Actuation of the actuator moves the dog into engagement with a second dog that is coupled to a side gear of the differential to thereby lock the side gear to the differential case.
