ABSTRACT:
A steering system for an articulated vehicle having one axle mounted thereon in a wagon-steer mode in addition to the conventional articulated-steer mode. A steering control valve, which is responsive to the movement of a manual steering control element, is ported to admit hydraulic fluid sequentially, first to a pair of wagon-steer cylinders and then to a pair of articulated-steer cylinders in both left and right steering control. The steering of the vehicle is initially through the wagon-steer movement of the one axle to facilitate high speed handling, which requires relatively small directional changes in the steering system, and is secondly through the articulated-steer movement in sequence to the wagon-steer movement to facilitate low speed maneuvering, which requires large directional changes in the steering system.
