Corner post-free carriage for a railway vehicle

Abstract

The invention discloses a corner post-free carriage for a railway vehicle, which comprises a floor (1), side wall boards (2) positioned on two sides of the floor (1), and end sheathings (3) positioned at two ends of the floor (1); the bottom sides of the side wall boards are bent upwards, and the bent parts (2) are subjected to assembly welding with corresponding sides of the floor (1) in a lapped way; the two ends of the floor (1) are bent upwards to form upper flanges which are lapped with the bottoms of the corresponding end sheathings (3) and are fixed by welding; and two sides of the end sheathings (3) are deformed and bent to form right-angle flanges which are subjected to assembly welding with corresponding ends of the side wall boards (2) in a lapped way. Compared with the prior art, the corner post-free carriage has simple structure, easy processing and manufacturing, less working procedures, low manufacturing cost, and light total weight of the whole, improves the carrying capacity, and contributes to reducing energy consumption of locomotives to save the energy.

Description

technical field [0001] The present invention relates to a railway freight car, in particular to a compartment structure of a railway freight car. Background technique [0002] The structure of the traditional railway freight car is as follows: Figure 5 , Figure 6 and Figure 7 As shown, it consists of floor 1, side wall panels 2, end wall panels 3, end beams 6, corner columns 7, corner column panels 8, side beams 9, cross beams 10, middle beams 11 and side columns 12, among which the floor 1 The two ends are respectively welded on two end beams 6, the two sides of the floor 1 are respectively welded on two side beams 9, side wall panels 2 are arranged on both sides of the side beams 9, and the two ends of the side wall panels 2 pass through the corner posts The plate 8 is welded on the corresponding corner post 7, and the bottom edge of the side wall plate 2 is welded to the side beam 9. A plurality of side columns 12 are arranged on the outer surface of the side wall p...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the corner columns are usually made of pressed angle steel or cold-formed rectangular hollow section steel, or welded by channel steel and corner column plates, there are many manufacturing processes in the production process, which increases the manufacturing complexity and product cost; in addition, The total weight of the carriage is relatively large, which will affect the load increase and increase the energy consumption of the locomotive, which is not conducive to energy saving

[0004] 2. The use of steel side beams will increase the manufacturing cost of the carriage, and also increase the weight of the carriage, which will increase the energy consumption of the locomotive during operation

The side columns and side beams are riveted and then assembled and welded. There are many processes, which will also increase the processing cost of the carriage during the manufacturing process.
