Abstract
A control device for a steering mechanism of a vehicle includes hydraulic means for laterally pivoting a pair of independently suspended guide wheels in response to rotation of a steering wheel of the vehicle. The hydraulic means includes a pair of double-acting jacks attached to respective guide wheels in such a manner that the extension of each jack pivots a corresponding guide wheel, and a pair of valves mounted on respective jacks for controlling the extension thereof. The valves are controlled by a pair of linkages which are connected to the steering wheel by a coupling mechanism in such a manner that the valves are simultaneously controlled in response to rotation of the steering wheel so that both guide wheels are laterally pivoted in the same angular direction.
