A steerable truck apparatus (20) for railroad cars for providing the controlled and uniform yawing of the axles (27, 28) of the truck. The truck apparatus (20) provides for a yawing response which is linear substantially throughout the range of movement of the axles (27, 28). The truck is further configured with pivotally supported pedestals (23, 24, 25, 26) for equalized load distribution. An improved axle bearing construction accommodates pivoting of the axle ends, and a damping apparatus provides stiffness in the steering response to reduce hunting of the wheels during straight-line travel.
L'invention concerne un nouveau système de bogie orientable (20) pour wagons de chemin de fer, qui permet de réguler et de rendre uniforme le mouvement de lacet des essieux (27, 28) de bogie. Le système de bogie (20) fournit une réponse en lacet qui est sensiblement linéaire sur toute la gamme du mouvement des essieux (27, 28). En outre, le système est doté de plaques de garde (23, 24, 25, 26) portées pivotantes destinées à égaliser la répartition des charges. La construction améliorée des boîtes d'essieux permet de faire pivoter l'extrémité des essieux et, en outre, un système d'amortissement introduit une certaine rigidité dans la sensibilité de direction pour réduire le lacet des roues sur les déplacements en ligne droite.
