ABSTRACT:
An undercarriage with a wheel set capable of self-steering independent of the vehicle body is disclosed. The undercarriage contains, in combination with hollow profile wheels in the wheel sets and primary elastic springs in the longitudinal direction, two lever systems which are self-adjusting, independent of each other and are arranged on the longitudinal sides of an undercarriage. The lever systems forcibly couple the axle ends of the wheel sets on the same rail in the longitudinal direction of the undercarriage and are movable only in opposite directions. The levers are further provided with a reversing member tiltably supported at the truck frame, the tilting motions of which are damped by a single damper assigned to each lever system, whereby in a structurally simple, rugged and low-maintenance manner, optimum limitation of the wheel set's freedom of motion relative to the truck frame is achieved in the longitudinal frame direction with respect to radial self-adjustment in track curves and, at the same time, high stability at high speeds is achieved.
