Title: Vehicle steering mechanism

Abstract: A system for providing differential steering in vehicles having spaced dual wheels steerable about vertical axes. The steered wheels are interconnected through chain drives acting on eccentrically journalled transfer pinions which are coupled together for simultaneous angular displacement and free to move laterally in a horizontal plane. The eccentricity is so arranged that for any steering angle of the vehicle, one steered wheel rotates through a given steering angle minus a small angle .theta., and the other steered wheel rotates through the same steering angle plus a small angle .theta., to provide differential steering for steering angles up to 180.degree..
