PURPOSE:To enable a vehicle to make a small turn, by supporting a vehicle body by means of right and left drive wheels alone to reduce the running resistance of the vehicle. CONSTITUTION:Upon stopping or low speed running of a vehicle auxiliary wheels 26 are grounded so that the vehicle body is supported by four wheels. When the running speed of the vehicle exceeds a predetermined speed, the auxiliary wheels 26 are moved toward a position where the wheels 26 are lifted from the ground, so that the vehicle body 1 is supported only by right and left drive wheels 3. In such a running condition, the attitude of the vehicle body 1 is always detected by left and right vehicle body detecting devices 40. In accordance with the result of the detection, the balance-weight is moved back and forth to hold the horizontal attitude of the vehicle body. |
