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.
Montage porteur latéral à contact constant pour châssis de roulement de wagon de marchandises. Ce montage comprend un mécanisme de transfert de force de charge ayant un trajet de transfert de force plus direct ou moins redondant entre la caisse du wagon pourvu de son chargement et le châssis latéral et les roues du bogie. Ce système permet : d'éliminer le besoin d'utiliser une structure de plaque centrale de traverse pivot pour le transfert de charge; de faire porter toutes les forces de charge par les dispositifs porteurs latéraux; de répondre aux normes de fonctionnement dynamique de l'Association of American Railroads; de réduire le poids du wagon tout en maintenant sa capacité de porter une charge. De plus, ce système s'adapte particulièrement aux bogies trois pièces utilisés largement dans le domaine des wagons de marchandises.
