Title (EN) LINEAR STEERING TRUCK
(FR) BOGGIE LINEAIREMENT ORIENTABLE
Abstract:
(EN) A steerable truck (300) for railroad cars is provided for controlled and uniform yawing of the axles (327, 328) of the truck (300), by providing a yawing response which is linear substantially throughout the range of movement of the axles (327, 328). Pivotably supported pedestals (333, 334) equalize load distribution, while an improved axle bearing construction accomodates pivoting of at least one axle end. A damping apparatus provides stiffness in the steering response so as to reduce hunting.
(FR) L'invention concerne un boggie orientable (300) pour wagons de chemin de fer, qui permet de contrôler et d'uniformiser le mouvement de lacet des essieux (327, 328) du boggie (300), en fournissant une réaction de lacet sensiblement linéaire dans toute la plage de mouvement des essieux (327, 328). Des supports montés pivotants (333, 334) égalisent la répartition de charge, tandis qu'un système de palier d'essieu amélioré permet le pivotement d'au moins une fusée d'essieu. Un dispositif d'amortissage assure la dureté dans la réaction de direction pour réduire l'effet de galop.
