ABSTRACT:
The transmission includes a hydraulically operated actuator for selectively controlling a locking mechanism for a differential mechanism interconnecting a motion input shaft and at least two motion output shafts. The lubricant for the differential mechanism is supplied by a pump to an actuator for the lock device with the pump being driven from the motion input shaft. In one embodiment, the pump and the actuator are disposed in a support for the differential mechanism. In a second embodiment, the pump is mounted on the housing and is provided with a reciprocating piston driven by a rotatable cam mounted for rotation with the differential casing. The plunger is biased in one direction by a spring in such a manner that the plunger is driven for a suction stroke by the cam and for a delivery stroke by the spring.
