Straddle type monorail vehicle body

Abstract

The invention discloses a straddle type monorail vehicle body. The straddle type monorail vehicle body comprises a bottom skeleton and apron board structures connected with the bottom skeleton. The apron board structures extend from one end of the vehicle body to the other end of the vehicle body, each apron board structure comprises an upper-layer apron board and a lower-layer apron board, and the tops of the upper-layer apron boards are connected with the skeleton in a rotating mode so that the upper-layer apron boards can be overturned outwards. The apron board structures wrap the two sides of the vehicle body skeleton as a whole, noise of the vehicle body is offset in the apron board structures wrapping the whole skeleton, in this way, a good sound insulation and noise reduction effect is achieved, and the whole vehicle body forms a complete shell; in addition, the upper layer and lower layer separation mode meets the requirements for appearance uniformity and continuity of the apron board structures extending from one end to the other end, guarantees connection with the outer side wall of the vehicle body and lowers manufacturing difficulty. The overall height of the vehicle body can be reduced in maintenance by disassembling the lower layers, so that the workshop requirement and operating difficulty are lowered. The upper-layer apron boards can be overturned, so that maintenance is facilitated for technicians.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a straddle-type monorail vehicle body. Background technique [0002] Most urban rail vehicles operate in urban areas with high population density. Compared with conventional double-track vehicles, straddle-type monorail vehicles are a special type of rail vehicles, which have only one track and are located in the middle of the vehicle. [0003] At present, straddle-type monorail vehicles in operation in China generally adopt a linear single-layer skirt structure, and the shape is relatively simple. Only lower skirts are installed at the running devices at both ends of the car body to cover and protect the running devices (mainly bogies) , and can play a role in noise reduction. When overhauling, the whole lower group board is dismantled. [0004] However, based on the uniqueness of the straddle-type monorail vehicle, compared with other urban rail vehicles, it is closer t...

AI Technical Summary

Problems solved by technology

[0004] However, based on the uniqueness of the straddle-type monorail vehicle, compared with other urban rail vehicles, it is closer to the surrounding buildings and has higher requirements for sound insulation and noise reduction. The above-mentioned design cannot meet the increasing sound insulation requirements of the standard

[0005] In addition, due to the large volume and high height of the running device, the single-layer skirt plate at the corresponding end is large in size, and the overall removal will lead to low maintenance efficiency and unsafe operation
