Title: Fully-locking torque-proportioning differential

Abstract: A fully-locking torque-responsive differential includes an annular coupling device arranged concentrically between an axially-extending hub portion on one side gear and the wall surface of the carrier bore in which the side gear is rotatably mounted. An axially-displaceable trigger pin is operable externally of the differential housing in which the carrier is rotatably mounted between first and second positions in which the coupling device is unlocked and locked, respectively. The trigger pin may be operated either automatically or manually by the vehicle operator, use being made of an electrical, hydraulic, pneumatic or cable-operated linear shifting member that extends through a sealed opening contained in the differential housing.
