ABSTRACT:
A freight railcar undercarriage constant-contact sidebearing arrangement provides a load force transfer mechanism with a more direct or less redundant force transfer path between the railcar body with its lading and the sideframe and wheels of a truck assembly, which system obviates the present use of a bolster center plate structure for load transfer, carries all the load forces through the side bearing assemblies, fulfills the dynamic operating requirements of the American Association of Railroads standards, reduces the weight of the railcar while maintaining the load-carrying capacity, and is particularly adaptable to three-piece truck assemblies in broad use on freight railcars.
