Abstract

The invention discloses a side frame of a railway freight car bogie. The side frame of the railway freight car bogie comprises a top plate, a web plate and a bottom plate. Grooves are symmetrically formed in the two sides of the web plate. Supporting plates are arranged in the grooves. A spring hole is formed in the center of the web plate. Triangular holes are further symmetrically formed in theweb plate. The top plate, the web plate, the supporting plates are connected with the bottom plate in a welded mode. The side frame of the railway freight car bogie is formed by welding of the top plate, the web plate, the supporting plates, a spring bearing platform, a vertical column and the like, molds are not required to be input for the side frame of a welded structure, the production cycle is short, and small batch production is achieved.

Description

technical field [0001] The present application relates to the field of railway freight car bogies, in particular to a side frame of a railway freight car bogie. Background technique [0002] In railway wagons, the side frame is the main load-bearing part of the cast steel three-piece bogie. It is a box-shaped integral casting structure as a whole. The middle part is provided with a bearing platform for placing springs, and the two ends are provided with supporting surfaces. The bottom is used for installation. Components such as wear plates and bearing saddles. In the prior art, the side frame of the cast steel three-piece bogie is an integrated casting structure, and the weight is between 300kg and 500kg. A new mold needs to be opened for the first production, the mold opening period is long, and the mold cost is high, which is not suitable for small batch production. . Contents of the invention [0003] The object of the present invention is to provide a side frame of ...
