ABSTRACT:
A steering linkage in which a pair of steering arms rotatably mounted on the vehicle frame are jointed by a tie rod to form, in combination, a parallelogram. For each wheel, a steering arm slidably engages a crank arm secured to a king pin that rotatably mounts the wheel to the frame. The pivot point of each steering arm is arranged so that a given angular rotation of both steering arms produces a differential angular wheel rotation that maintains the point of intersection of the steered wheel axes proximate the axis of the fixed wheels or more generally, the rotational axis of all wheels proximate a fixed point.
