ABSTRACT:
A vehicle steering system comprises a set of steering cylinders which, when actuated, effect vehicle steering. The set of steering cylinders comprises at least two proportionately sized cylinders. The proportionate sizing of the cylinders is determined by the rod-end area to head-end area ratio of the cylinders. A steering control means directs two different flows to the respective cylinders in accordance with the proportionate sizing thereof to effect actuation thereof for steering purposes. One of these flows is directed to the head end of one cylinder and the other flow is directed to the rod end of the other cylinder. The steering control means also receives the return flow from the proportionately sized cylinders. The steering control means comprises a valve means for directing the flows to the cylinders and for receiving the return flows, a metering means for metering one of the flows, and an operator controlled input for actuating the valve means and the metering means to effect steering of the vehicle.
