ABSTRACT:
The invention describes vehicles where the steering effect of the driver-selected wheel angles is made identical to the steering effect of positively and independently driving the driven wheels.Means of delivering most of the power to each of the driven wheels by means of shaft drives is also described. Here speed-correcting differentials are close coupled to each driven wheel where the first input to the said differentials is by means of shaft drives, and the second input to the said differentials is provided by means of speed-correcting hydraulic or electric motors.
