ABSTRACT:
A vehicle steering system for vehicles with steerable front wheels and steerable rear wheels. A specially elongated pinion steering shift includes two groups of pinion gears. One of the first group of pinion gears meshes with a gear on a steering rack for the front wheels; and, simultaneously, one of the second group of pinion gears meshes with a gear on a steering rack for the rear wheels. A vehicle user can selectively shift the steering shaft to four distinct operating positions. Each operating position provides a specific steering mode, including: a first steering mode for steerage of front wheels with rear wheels neutral, a second steering mode for steerage of rear wheels with front wheels neutral, a third steering mode for coincidence-phase steerage of front wheels and rear wheels, and a fourth steering mode for reverse-phase steerage of front wheels and rear wheels. This invention can be similarly applied to a steering system with worm shaft and ball nut, or other types of steering systems.
