Abstract
A four-wheel steering system for an automotive vehicle includes a linkage drivingly connected at its front end to a front wheel steering mechanism, and a connecting mechanism assembled in combination with a rear wheel steering mechanism to drivingly connect the linkage to a pair of operation rods of the rear wheel steering mechanism in such a manner that the operation rods are axially displaced in response to movement of the linkage to steer a pair of dirigible rear road wheels. The connecting mechanism is designed to control the steering angle and direction of the rear road wheels relative to those of a pair of dirigible front road wheels without causing any change in the alignment of the rear road wheels.
