Abstract
A motor vehicle having a plurality of drive wheels and a steerable wheel. The steerable wheel is rotatably mounted on the frame with an upright steering post. A hydraulic powered transversely movable cylinder is connected to a sprocket mounted on the steering post with a pair of chains. The cylinder is linearly movable relative to a piston and a transverse rod. Adjustable members connect opposite ends of the rod to the frame and hold the rod in linear tension. The cylinder is supplied with hydraulic fluid under pressure from a pump driven by an internal combustion engine. A control valve having a spool connected to the vehicle steering wheel controls the flow of hydraulic fluid under pressure from the pump to the cylinder thereby steering the vehicle.
