Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] refer to Picture 1-1 , 1-2 , figure 2 , the new aluminum alloy subway car body of the present invention, the structure includes a roof structure 1, a front frame structure 2, an end wall structure 3, two side wall structures 4, and an underframe structure 5.

[0033] The roof structure 1 is used to install the air conditioning unit and the pantograph. The interface between the roof structure 1 and the front frame 2 is riveted and fixed, and the interface between the roof structure 1 and the end wall structure 3 and the side wall structure 4 is fixed by welding. .

[0034] The interface between the front frame structure 2 and the roof structure 1 and the underframe structure 5 is fixedly connected by riveting.

[0035] The interfaces between the end wall structure 3 and the roof structure 1, the side wall structure 4 and the underframe structure 5 ...

Abstract

A novel aluminum alloy subway train body is characterized in that a train roof edge beam 1-1 is made of large-section aluminum alloy sections, beams and columns of a front end framework structure areformed by assembling and welding square steel, connectors of an end wall framework and end wall plates are fixedly connected in a welded mode to form a frame structure, and side wall window area sections are provided with grooves. The end underframe assembly and the buffer beam assembly adopt high-strength steel plate welded structures, the underframe edge beam, the first-position end beam, the second-position end beam and the floor assembly adopt large-section aluminum alloy sections, two ends of the vehicle body underframe are respectively provided with two energy-absorbing anti-creeping devices made of high-strength steel materials, and the underframe is provided with an energy-absorbing structure end underframe made of high-strength steel materials. The vehicle body meets the requirements of newly developed Shanghai No.6 and No.8 lines, and the structure of the vehicle body meets the performance requirements of strength, fatigue and the like.

Description

technical field [0001] The invention belongs to the technical field of subway vehicle manufacturing, and in particular relates to a novel aluminum alloy subway car body. Background technique [0002] At present, the aluminum alloy body of urban railway vehicles generally has two types: A type and B type. The length of the A type aluminum alloy body is 24400mm and the width is 3000mm, and the length of the B type aluminum alloy body is 19600mm and the width is 2800mm. The length of the car body of Shanghai Metro Line 6 and Line 8 is required to be 19500mm, and the width of the car body is required to be 2600mm, which is quite different from the ratio of the shape and size of the A and B car bodies. At the same time, the static strength load requirements for the aluminum alloy car body of type A urban railway vehicles are generally 1200KN longitudinal compression load and 960KN longitudinal tension, and the static strength load requirements for aluminum alloy car bodies of typ...
