Abstract: A tracked vehicle produces a pressure no more than 3 psi on the ground by increasing the number of contact points on the inner surface of the track. The stiffness of the track is also selected to minimize bowing between the idler wheels or rollers. The track is therefore kept substantially straight between the rollers so increase the efficiency associated with transferring power to track. The drive sprocket is positioned above the ground so as to eliminate complexity in the design and yet effectively transmit power to the tracks. Positioning the drive sprocket above ground also prevents derailing of the track. The track is also held in a constant state of tension on the driver sprocket and the roller. This too prevents derailment. The undercarriage of the vehicle includes torsion axles and sealed bearings to provide for a lower maintenance track. Components associated with the undercarriage do not require constant greasing and cleaning of the idler wheels.

In engine stop, the switch over device switches to the sub-battery as a power supply of operating load. Accordingly, because the sub-battery can absorb slowdown energy, driving efficiency of the power-generator or motor at slowdown becomes excellent.

Abstract: On the outer periphery of a bearing 10 for supporting a worm 71 rotating interlocked with the rotation of a steering assist motor 6 inside the housing 8, elastic members 20 are provided to restrain the bearing 10 from moving in the radial direction thereof. The force for the restraint by the elastic members 20 is made different depending on the position in the peripheral direction thereof. A portion of the elastic member, wherein the force for restraining the movement of the bearing 10 in the radial direction is small, energizes the worm 71 to the meshing position of the worm 71 and a worm wheel 72. Another portion, wherein the force for restraining the movement is large, restrains the worm 71 from moving along the lead of the worm wheel 72. With this configuration, the elastic members 20 can reduce the amount of the backlash at the meshing portion of the worm 71 and the worm wheel 72, and can make the rotation torque applied to the meshing portion of the worm gears relatively small.
