초록

A 4-wheel mobile vehicle including provision for controlling the steering position of each of the four (4) wheels so that every wheel\s rolling axis will intersect at a common central point around which the vehicle will turn. The control is provided by a pair of cables which can interconnect each of the pair of wheels on each side of the vehicle to turn through similar turns in the opposite direction, and wherein the linear position of the cables are provided by a pair of specially cut cams which are positioned by the steering column. Each pair of wheels...
