ABSTRACT:
An improved swing-motion truck in which the transom has been replaced by a pair of transverse radius or tie rods for coupling the two rocker seats of the two side frames of the truck. The ends of the rods are directly coupled to anchor brackets formed as part of the side-frame rocker seats via an elastomeric connection. The suspension springs of the railway freight car truck are seated directly upon the upper flat surface of the two rocker seats of the side frames of the truck, so that lighter-weight freight cars may be accommodated, without a friction-dependent coupling between the rocker seats and rods interconnecting the rocker seats, and where an overall lower height truck results to provide a low-deck car. The cooperating limit stops for lateral motion of the truck are mounted directly on the rocker seats themselves.
