ABSTRACT:
A differential with an improved locking mechanism is provided. The differential includes first and second clutch members in the form of a differential case having a first set of teeth and a an axle shaft mounted clutch collar having a second set of teeth. A yoke urges the clutch into an out of engagement and is supported on a pivot shaft. The yoke is selectively urged in one direction by an actuator acting on a lever on the pivot shaft. The lever is coupled to the yoke by a spring. The yoke is urged in an opposite direction by one or more return springs mounted on the same pivot shaft. The compact nature of the locking mechanism and the balance of forces provided by the springs and actuator provide an inexpensive and reliable locking mechanism.
