Abstract
A land vehicle steering system capable of selectively moving the left and right steerable wheels inboard and outboard of the vehicle, and selectively adjusting the distance between the left and right steerable wheels. The steering system includes left and right steering assemblies. Each assembly includes: a pivot arm pivotally secured to the vehicle about a first pivot axis; a first hydraulic cylinder secured between the pivot arm and the vehicle; a wheel end pivotally secured to the pivot arm about a steering axis; and, a second hydraulic cylinder secured between the wheel end and the pivot arm. Actuation of the first hydraulic cylinders rotates the pivot arms about their first pivot axes and moves the wheel ends inboard and outboard of the vehicle. Actuation of the second hydraulic cylinders rotates the wheel ends and steerable wheels thereon relative to their pivot arm for steering the vehicle.
