The planetary steering differential includes first and second interconnected gear trains. First and second gear trains are used for rotating output members in the same direction at the same speed in response to rotating solely a first input and holding a second input stationary. Rotation solely the second input arrangement and holding the first input arrangement stationary the output members are rotated in opposite directions at the same speed. The first input arrangement is driven by a transmission, and the second input arrangement is driven by a reversible steering motor.

1. A planetary steering differential adapted to be driven in use by a transmission and a steering motor, comprising:a first input arrangement adapted to be driven by the transmission; a second input arrangement adapted to be driven by the steering motor; first and second output members; first and second gear trains for rotating said first and second output members in the same direction and at the same speed in response to rotation solely of said first input arrangement and holding said second input arrangement stationary with the speed of the output members being reduced from the speed of the first input arrangement, and for rotating said output members in opposite directions at the same speed in response to rotation solely of said second input arrangement and holding said first input member stationary; said first and second gear train each including first and second interconnected planetary reduction arrangements respectively, said first input arrangement being connected to said first planetary reduction arrangement and said second input arrangement being connected to said first planetary reduction arrangement; and said first and second gear trains being arranged on and interconnected solely along a common central axis.
