Railway wagon bogie and railway wagon

Abstract

A railway wagon bogie and a railway wagon are provided. The bogie includes wheel sets, side frames provided with triangular holes, a swing bolster provided with a preset hole in its body, and cross-braced rods. Cavities are formed in the side frames, symmetric around the center of the side frames, and located below the triangular holes. A connecting seat is provided in each of the cavities, and provided with a vertical mounting hole in a middle portion of the connecting seat. The cross-braced rods are elastically connected to the connecting seats through the mounting holes. In the railway wagon bogie and the railway wagon, the strength of the bogie is increased.
