<p>A retractable steel guide wheel assembly adaptable for installation on a pneumatic tired vehicle for transforming the vehicle into a convertible rail-highway vehicle. The guide wheel system is driven from the vehicle suspension system and provides a four corner structure wherein each corner is supported in a substantially identical manner. In the extended or supporting position for the steel wheels, the front wheels of the vehicle are elevated from engagement with the rails, and the rear wheels are maintained in engagement with the rails in a manner wherein the optimum force or weight is maintained on the rear wheels to provide optimum traction for driving and for braking vehicle during travel thereof along the rails. The wheels are retracted in a manner similar to the retractable wheels of an aircraft, but in an opposite direction of movement with respect thereto.</p> |
