The present invention provides a joint for transferring load from the underframe of a locomotive to the cant rail of its car body. The joint includes a base connected to the underframe of the locomotive with a body portion attached thereto. This body portion carries a generally diagonally situated member connected to the cant rail of the car body of the locomotive, such that the load from the underframe is transferred to the base of the joint, through the body portion of the joint, to the diagonally situated member and to the cant rail during bending of the underframe of the locomotive. In another aspect of the present invention, a joint is provided which is generally flexible to accommodate bending of the car body and underframe of the locomotive relative to their respective stiffnesses.

L'invention concerne une articulation pour transférer une charge depuis le châssis inférieur d'une locomotive jusqu'au brancard de sa carrosserie. L'articulation comprend une base reliée au sous-châssis de la locomotive, ayant une partie de carrosserie fixée sur celle-ci. Cette partie de carrosserie supporte un élément situé de manière générale diagonalement relié au brancard de la carrosserie de la locomotive, de sorte que la charge provenant du sous-châssis est transférée à la base de l'articulation, à travers la partie de carrosserie de l'articulation, jusqu'à l'élément situé diagonalement et jusqu'au brancard pendant une incurvation du sous-châssis de la locomotive. Dans un autre aspect de la présente invention, une articulation est fournie qui est de manière générale souple pour accepter une incurvation de la carrosserie et du sous-châssis de la locomotive par rapport à la rigidité respective.
