Aluminum alloy double-layer CRH train body structure and CRH train

Abstract

The invention provides an aluminum alloy double-layer CRH (China rail highspeed) train body structure which comprises floors, edge beams, side walls, end walls and a train roof, the floors comprise a lower floor and a middle floor, and the lower floor comprises end floors at the two ends, end sealing structures and a middle floor; the two sides of the middle floor are fixedly connected with the side walls to divide the space in the train body into an upper passenger room and a lower passenger room; the side walls, the edge beams and the floor structures are matched with one another, a plurality of windows are formed in the middle of each side wall and located in the upper passenger room and the lower passenger room respectively, and pedaling doors and equipment mounting doors are arranged at the two ends of each side wall. The upper passenger room containing space and the lower-layer passenger room containing space of the train can be provided, and the passenger room containing space is almost doubled.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle manufacturing, and in particular relates to an aluminum alloy double-layer EMU car body structure and an EMU. Background technique [0002] The existing EMU car bodies are all single-layer car body structures, made of aluminum alloy, assembled and welded by large hollow aluminum alloy profiles, and are thin-walled cylindrical overall load-bearing structures, mainly composed of roofs, side walls, end walls and The chassis and other large parts are composed of thin-walled hollow profiles that are basically as long as the car body. [0003] With the development of the economy and society, some lines with dense passenger flow, or main line or branch line railways where it is difficult to continue to increase trains due to line density and hub capacity constraints, often have very tight tickets. To solve this problem, it is necessary to increase the body of the train There are two ways to increas...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that the car body of the traditional EMU is small and the number of passengers cannot meet the demand, thereby providing a double-layer EMU car body structure and an EMU, which can provide the accommodation space of the upper and lower layers of the passenger compartment of the vehicle , the accommodation space of the passenger room has been greatly increased to ensure the smooth travel of people
