A structural device is attached to each sideframe pedestal jaw of a railcar truck wherein the bearing adapter is joined to the sideframe and is prevented from rotating within the pedestal jaw opening. The bearing adapter inboard and outboard faces maintain a parallel relationship with the sideframe inboard and outboard faces during operations, including curving, thereby causing the truck axles to remain at a right angle with respect to the sideframes. Maintaining this right angular relationship substantially curtails truck wheel misalignment, which directly effects truck hunting and curving.
Cette invention concerne un dispositif monté sur chacune des branches de la plaque de garde d'un longeron de bogie ferroviaire pour verrouiller l'adaptateur de palier au longeron et l'empêcher de tourner dans l'ouverture de la plaque de garde. Les faces intérieure et extérieure de l'adaptateur de palier restent parallèles aux faces intérieure et extérieure du longeron en cours de marche, y compris dans les courbes, de manière à garder les essieux perpendiculaires aux longerons. Cette disposition constructive réduit sensiblement les désalignements de roues qui ont une incidence directe sur la tendance à la marche en lacet et sur l'inscription en courbe.
