摘要:
A freight car bogie and a freight car are provided. The freight car bogie includes two wheel set assemblies, side frames, and a bolster. The freight car bogie further includes a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod are crossed in an X form to pass through reserved holes at two sides of a belly of the bolster. The first connecting rod and the second connecting rod are separated from each other at a crossing portion. The first connecting rod includes a first end and a second end. The second connecting rod includes a third end and a fourth end. The first end and the third end are resiliently connected to one of the side frames and symmetrical about a center line of the bolster. The second end and the fourth end are resiliently connected to the other side frame and symmetrical about the center line of the bolster. Therefore, a warp resistant rigidity of the freight car bogie is increased, and an operation speed and capability for adapting to track irregularities of a three-piece casting steel bogie are raised.
