Abstract

A differential driving system capable of operating as a steering system for skid steer vehicles having two differentials, a steering differential (11) dedicated to steering and a propulsion differential (1) having its planet carrier (2) adapted to be driven by a vehicle motor (5) and providing drive shafts (6, 7) for the opposite sides of a vehicle. One of the gears of the steering differential is driven by a variable speed reversible motor (17), which is adapted not to rotate for straight running, and the other two gears are each connected to rotate with one of the drive shafts (6, 7). No rotation of the gear of the steering differential driven by the reversible motor (17) means that the other two gears rotate in the same direction and the drive ratios of the connection means ensure that the angular velocities of the two drive shafts (6, 7) are equal.
