ABSTRACT:
A vehicle differential control wherein the two axles and wheels thereon are influential in controlling the differential. Thus, speed sensors are on the two axles and link mechanisms connect the sensors to a valve unit which controls the flow of fluid to the differential and thus controls the operation of the differential and the subsequent speed of the respective axles. Also, the wheels on the axles are steerable wheels, and there is interconnecting mechanism between the wheels and the differential control mechanism so that when the wheels are steered the control mechanism is actuated to again influence the operation of the differential and thus rotate the respective axles accordingly. As such, there is a steering compensated differential controlled device which is both torque and speed sensed, and there is a wheel steering position compensated device which also influences the operation of the differential. The system is such that it assures traction control of all drive wheels at all times.
