AI Technical Summary
Technical Problem
The traditional bolster structure has a large deadweight, which limits the effective load of railway freight cars and reduces transportation efficiency and economic benefits.
Method used
The support structure is distributed in a "Y" shape between the upper and lower walls of the bolster. Combined with the support shank and process hole design, a stable frame structure is formed to evenly distribute the load and reduce local stress concentration.
Benefits of technology
The load-bearing capacity and stability of the bolster are improved, the dead weight is reduced, the effective load of railway freight cars is increased, and the transportation efficiency and economic benefits are improved.

Abstract
The utility model relates to the technical field of railway wagons, and discloses a casting swing bolster inner cavity supporting structure which comprises two side walls, a swing bolster upper wall and a swing bolster lower wall, the supporting structure is distributed between the swing bolster upper wall and the swing bolster lower wall in the length direction, and the supporting structure is of a Y-shaped structure. The swing bolster comprises a swing bolster upper wall and a swing bolster lower wall, side bearing boxes are arranged on the two sides of the swing bolster upper wall respectively, the branch portion of the Y-shaped structure is located below the side bearing boxes, a supporting shank plate is connected between the swing bolster upper wall and the swing bolster lower wall, and auxiliary holes are formed in the supporting shank plate. According to the utility model, through the elaborate arrangement of the Y-shaped structure and the fabrication holes, the bearing capacity of the swing bolster is enhanced while the dead weight of the swing bolster is reduced, so that the effective load of a railway wagon is increased, and the transportation efficiency and the economic benefit of the railway wagon are improved.
