Problems solved by technology

In order to ensure the force and load of the whole vehicle, the opening area of ​​the window is limited to a small range, and the side wall panels of sufficient width must be ensured at the side of the door and the window, which will lead to insufficient light in the compartment and also affect the appearance of the vehicle
In addition, the manufacturing process of this car body side wall is also relatively complicated.

Embodiment Construction

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and examples. However, the invention is not limited to the examples given.

[0012] As shown in Fig. 2, the novel side wall of the subway vehicle of the present invention comprises upper side beam 1, lower side beam 7 and vehicle window 4, is characterized in that: have the profile column 5 that is distributed with the width of car door, vehicle window opening, this profile column The upper and lower ends of 5 are welded into one body with the upper side beam 1 and the lower side beam 7 respectively, and the window area between adjacent profile columns has a window upper plate 8 and a window lower plate 9 riveted and fixed with the upper side beam 1 and the lower side beam 7 respectively, The vehicle window 4 glass is located between the upper window plate 8 and the lower window plate 9 .

[0013] Since the force at both ends of the carriage is relatively small, ...

Abstract

The side wall for underground vehicle consists of upper edge beam, lower edge beam and window, and has spaced uprights of sections with upper end and lower end welded separately to the upper edge beam and the lower edge beam, upper window plates, lower window plates and glass windows mounted onto the upper window plates and the lower window plates. Unlike available technology, which has bearing side wall plates, the present invention has bearing uprights, capacity of increasing window area, improved look and other advantages.

Description

technical field [0001] The invention relates to a car body side wall of a subway vehicle, in particular to a novel side wall structure of a subway vehicle. Background technique [0002] At present, the aluminum alloy subway vehicle currently in use in China has a body side wall structure as shown in Figure 1, which is to use a plurality of aluminum alloy hollow profiles 3 to be stacked and welded into a side wall panel, and then combined with the side wall side beam 1 and the side wall bottom beam 7 and the column 2 and the beam (not shown in the figure) that are used to strengthen the strength of the car door and the window are integrally assembled and welded into a side wall structure. 10 in Fig. 1 indicates the door area. In this type of side wall structure, the vertical load on the upper part of the car body is mainly transmitted downward through the side wall panels, while the doors and windows are formed through openings on the side wall panels. In order to ensure th...
