ABSTRACT:
A tracked vehicle is provided with an epicyclic steering differential interposed between the internal combustion engine and the track drive wheels. A reversible hydraulic motor is operatively associated with the differential for operating the steering of the vehicle. The differential includes a double epicyclic train which divides the torque from the internal combustion engine. The hydraulic motor acts on two elements of the train which are connected for rotation with each other about the central axis of the differential, and which rotate in equilibrium with each other when the vehicle is travelling a straight line.
