The present invention provides a railway truck sideframe with a strengthened bottom member. The sideframe comprises an elongated top compression member, two diagonal tension members extending downwardly at acute angles from near the ends of the top compression member, and a bottom member joining the other ends of the diagonal tension members. The top surface of the bottom member is usually referred to as a spring seat as such top surface provides support for the spring group on which the railway truck bolster is supported. The bottom member and attached diagonal tension members are strengthened by the addition of internal support ribs within the generally hollow bottom member near the intersection with the diagonal tension member. An increased thickness in the intersection of the top surface of the bottom member and the diagonal tension member and/or column is also provided.
La présente invention a pour objet un châssis de bogie dont le longeron est renforcé au niveau de son élément inférieur. Le longeron comporte un contrefort supérieur de forme allongée, deux pièces diagonales en traction orientées vers le bas et disposés à angles aigus au voisinage des extrémités du contrefort supérieur, et un élément inférieur joignant les autres extrémités des pièces diagonales en traction. La face supérieure de l'élément inférieur est habituellement appelée siège de ressort, celle-ci servant de support au bloc-ressorts supportant le bogie. L'élément inférieur et les pièces diagonales en traction sont renforcés par l'ajout de nervures de renfort disposées à l'intérieur de l'élément inférieur à proximité de l'intersection avec les pièces diagonales en traction. La face supérieure de l'élément inférieur a également fait l'objet d'une augmentation en épaisseur au niveau de l'intersection des pièces diagonales en traction et de la colonne.
