ABSTRACT:
Differential reduction drives on opposite sides of a vehicle are steer driven by a pair of worm gears (110) meshed with worm wheels (111) inputting steering torque into each reduction drive. The worm gears are rotationally interconnected so that the steering torque applied to the reduction drives is respectively equal and opposite. The arrangement allows a simple steering control shaft (46) to receive steering control torque for normal turning and driving torque for propulsion drive-assisted pivot turning. A pivot turn brake (120), applied to the drive torque train, can make pivot turning precise.
