Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with accompanying drawing

[0018] refer to image 3 , The new lightweight aluminum alloy subway end wall structure of the present invention includes an upper wall panel 1 and two lower wall panels 2, and consists of only three parts, wherein the two lower wall panels are aluminum alloy profiles of the same section. The entire end wall structure only needs two types of cross-sectional aluminum alloy profiles, which reduces the cost of profile molds and vehicle costs. The interface between the upper wall panel 1 and the two lower wall panels 2 is fixedly connected by welding. Only this part of the entire end wall has a weld seam. The structure is simple, the weight is light, and the welding process is good, which reduces the time for welding and post-welding repairs. The rear end wall has high flatness.

Abstract

A novel lightweight aluminum alloy subway end wall structure comprises an upper wall plate and two lower wall plates. Connectors of the upper wall plate and the two lower wall plates are fixedly connected in a welded manner. The novel lightweight aluminum alloy subway end wall structure is characterized in that the upper wall plate is made of a large-section lightweight aluminum alloy section, theinstallation positions of the upper wall plate, a top sealing frame of a through channel , an interior trim top plate of the through channel and an end wall interior decoration top plate are each ofa square cavity structure with one thick side and three thin sides; and protruding cross sections, shaped like the Chinese character 'ri', of the upper wall plate and the lower wall plates are each ofan end wall and end door frame structure, and the installation positions of the lower wall plate and sealing frames at the two sides of a through channel are each of a square cavity structure with one thick side and three thin sides. According to the novel lightweight aluminum alloy subway end wall structure, corresponding unified standards of core structure parameters such as aluminum material model selection and boundary dimension characteristics are provided for a new vehicle model, so that the vehicle body design efficiency is improved; and the design risk is reduced, so that a referencebasis is provided for realizing platformization, standardization and modularization of the aluminum alloy vehicle body end wall structure.

Description

technical field [0001] The invention belongs to the technical field of subway vehicle body manufacturing, and in particular relates to a novel lightweight aluminum alloy subway end wall structure. Background technique [0002] At this stage, whether in terms of performance or environmental protection, the lightweight of urban railway car bodies has become an inevitable trend. [0003] The end wall structure is an integral part of the urban railway car body. At this stage, there are two types of car body end wall structures for urban railway vehicles and aluminum alloy subways. One is the end wall of the plate beam structure, and the other is the end wall of the aluminum profile welded structure. [0004] 1) Plate beam structure end wall: see details figure 1 , The structural feature is that the column B is welded with the beam D and the longitudinal beam C to form an end wall skeleton, and then welded with the upper wall panel A and two end wall panels D and E to form an ...
