Abstract

A differential for a wheel set provided with three modes of operation. A stub axle and wheel axle in combination provide drive torque to one wheel of the wheel set. A single wheel axle provides torque to the other wheel of the wheel set. The stub axle and wheel axle are releasably interconnected by a clutch ring and when connected provide conventional differential operation including equalized torque applied from a propeller shaft to the wheels of the wheel set. Alternatively the clutch ring can also provide connection to the differential casing to insure common rotation of the two wheels. In the third mode, the clutch ring does not connect any of the components and the non-resisted rotation of the stub axle effectively disconnects the wheel axles from the propeller shaft. An actuator provides actuation from a position at the exterior of the differential into and through the case to the clutch ring. The actuator includes bearing type interconnections to achieve axial movement even though the components have different rates of rotation.
