Abstract

A novel sidewall for subway vehicle comprises an upper edge beam, a lower edge beam, windows, and upright columns. The upper and lower ends of the upright column are respectively welded with the upper and lower edge beams to be a whole. The window between the adjacent upright columns is provided with an upper board and a lower board, that is respectively and fixedly connected with the upper beam and the lower edge beam, and the window is arranged between the upper and lower boards. The original vehicle sidewall is removed, and the conventional mode that the vehicle sidewall bears the force is changed. The vertical load at the upper part of the vehicle is completely transmitted downwardly by the upright columns, the space between the upright columns is determined by the opening width of the vehicle door and window, and the vertical window width is no longer limited by the vehicle sidewall, so as to correspondingly increase the useful area of the window, guarantee the sufficient and bright light in the carriage, and make the subway vehicle more beautiful and modern. The utility model has the advantages of modularized production, simple production process, and high work efficiency.

Description

Novel sidewall for underground vehicle

Technical field

The utility model relates to a kind of car body side wall of railcar, particularly a kind of novel sidewall for underground vehicle structure.

Background technology

Present domestic current aluminum alloy subway vehicle, its car body sidewall structure as shown in Figure 1, be to be welded into framed side wallboard with polylith aluminium alloy hollow section bar 3 laminations, then with side wall roof rail 1, side wall under side bar 7 and the being used for column 2 of strengthening car door, vehicle window intensity become sidewall structure with crossbeam (figure does not draw) integral assembly welding.10 signal car door districts among Fig. 1.In the sidewall structure of this kind form, the vehicle body upper portion vertical load mainly transmits downwards by framed side wallboard, and car door, vehicle window are by forming in the framed side wallboard upper shed.In order to ensure the stressed of car load and carrying, the aperture area of vehicle window is limited in the small range, and Men Bian and window limit also must guarantee to have the framed side wallboard of enough width, will cause insufficient light in the compartment like this, has also influenced the attractive in appearance of vehicle simultaneously.In addition, also more complicated of this car body side wall manufacturing process.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of novel sidewall for underground vehicle is provided.

The technical scheme that its technical matters that solves the utility model adopts is as follows: a kind of novel sidewall for underground vehicle, comprise roof rail, following side bar and vehicle window, it is characterized in that: having with car door, vehicle window A/F is the section bar column that spacing distributes, the upper and lower end of this section bar column is integrally welded with roof rail and following side bar respectively, vehicle window district between the adjacent profiles column has respectively the window upper plate and the window lower plate of captiveing joint with following side bar with roof rail, and glass for vehicle window is contained between window upper plate and the window lower plate.

The beneficial effects of the utility model are as follows: cancelled original car body framed side wallboard, changed the mode of traditional and carrying stressed by the car body framed side wallboard, the vehicle body upper portion vertical load is transmitted downwards by the section bar column fully, the spacing of column is by the A/F decision of car door, vehicle window, and the vehicle window A/F no longer is subjected to the restriction of car body framed side wallboard, therefore can corresponding increase vehicle window payload space, guarantee bright and clear in the compartment, become clear, make subway train more attractive in appearance, have modernized breath; By changing the spacing between the column, can change the size of car door spacing and vehicle window neatly; The agent structure of side wall is by section bar column and roof rail, descends side bar integrally welded, can realize the modularization manufacturing, work simplification, work efficiency height; The window upper plate of side wall can adopt the riveted joint mode to captive joint with the window lower plate, does not have the welding distortion, and easy to process, planeness is good; Both can adopt riveted joint to be connected also between sidewall structure and roof and the underframe and can adopt welding process, and traditional side wall must adopt the welding manner connection; The section form of section bar column can be adjusted accordingly according to the variation of interior structure, can realize that multisystem is integrated.

The specific embodiment

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.

As shown in Figure 2, the utility model novel sidewall for underground vehicle, comprise roof rail 1, following side bar 7 and vehicle window 4, it is characterized in that: having with car door, vehicle window A/F is the section bar column 5 that spacing distributes, the upper and lower end of this section bar column 5 is integrally welded with roof rail 1 and following side bar 7 respectively, vehicle window district between the adjacent profiles column has respectively window upper plate 8 and the window lower plate 9 with roof rail 1 and following side bar 7 riveted and fixed, and vehicle window 4 glass are between window upper plate 8 and window lower plate 9.

Because it is stressed less that the two ends, compartment are located, in order to make the car load stress balance, the further feature of the utility model is: adopt the less relatively section bar column in cross section at the two ends, compartment.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.

Claims

1, novel sidewall for underground vehicle, comprise roof rail, following side bar and vehicle window, it is characterized in that: having with car door, vehicle window A/F is the section bar column that spacing distributes, the upper and lower end of this section bar column is integrally welded with roof rail and following side bar respectively, vehicle window district between the adjacent profiles column has respectively the window upper plate and the window lower plate of captiveing joint with following side bar with roof rail, and glass for vehicle window is contained between window upper plate and the window lower plate.
