ABSTRACT:
In a four-wheel steering system for automotive vehicles of the type having a front rack and pinion steering gear of the front wheels and a rear rack and pinion steering gear for the rear wheels, a gear box is disposed between the control shaft from the front steering gear and the pinion shaft of the rear steering gear. A crank assembly having a variable eccentricity wrist pin is disposed on the end of the control shaft within the gear box. The wrist pin is slidably received in a track on a gear sector in the gear box. The gear sector meshes with a spur gear on the end of the rear pinion shaft within the gear box. In a null position of the wrist pin, the latter is on the axis of rotation of the control shaft so that no rear steering occurs. When the wrist pin is moved from the null position and the control shaft rotated, the gear sector is pivoted in a direction corresponding to the direction of displacement of the wrist pin thereby to rotate the spur gear and steer the rear wheels.
