Abstract
This invention applies the linkage connected between the interaxle yokes of a truck and a railroad vehicle car body so as to create radially steered alignment of wheelsets on circular curves without reference to the truck frame. Forces exchanged between the wheelsets and the car body are essentially longitudinal and no significant lateral forces are created on the truck frame or car body from the steering action. The steering linkage utilizes the longitudinal component of relative motion of a point on the car body with reference to the vehicle truck to cause relative pivotal movement of the interaxle yokes thereby guiding the wheelsets to a radial alignment. Radial alignment is achieved by suitable proportioning of the links of the mechanism.
