Abstract:

A four-wheel steering system for a remote control vehicle. The system includes a pair of steering actuators driving a pair of front bell cranks. A front toe link is pivotally connected to each of the spaced front bell cranks for lateral translation. Right and left front tie rods are each pivotally connected between corresponding ends of the front toe link and a corresponding front steering knuckle. An elongated center tie rod is pivotally connected between one front bell crank and one of a pair of rear bell cranks. An elongated rear toe link is dependently pivotally connected to the pair of rear bell cranks for lateral translation. Right and left rear tie rods are each pivotally connected between corresponding ends of the rear toe link and corresponding right and left rear steering knuckles whereby the front knuckles steer in one direction while the rear knuckles steer in an opposite direction.
