ABSTRACT:
An all-wheel steered vehicle in which all wheels are always parallel and have an equal role in steering the vehicle. It consists of a plurality of wheel assemblies capable of wheel rotation about the wheel's axis and wheel assembly rotation about the wheel's vertical axis. These wheel assemblies are fixed normally to (at right angles to) and evenly spaced around a circle on the chassis (17). These wheel assemblies are attached to a common linkage (18) which maintains the wheels in parallel, but allow the wheel assemblies to rotate simultaneously about their vertical axes. The cab (21) of this vehicle is rotatable about the center of the circular chassis in a plane parallel to the chassis. The cab is in linkage with the wheel assembly's linkage such that a rotation of the cab relative to the chassis causes a simultaneous and equal rotation of all of the wheel assemblies about their vertical axis. That is, both the cab and all of the wheels are maintained parallel to one another. The steering mechanism is such that turning the steering wheel (23) in the cab, rotates the cab with respect to the chassis and simultaneously rotates all the wheels on their vertical axes, changing the direction of the vehicle. All wheels have an equal role in steering the vehicle.
