Vehicle body, railway vehicle and built-in assembly of railway vehicle

Abstract

The invention provides a vehicle body, a railway vehicle and a built-in assembly of the railway vehicle. The interior assembly of the railway vehicle comprises a floor framework and an interior wall plate installed on the railway vehicle; a vertical handrail, the first end of the vertical handrail is hoisted on a vehicle body top plate of the railway vehicle, and the second end extends into a passenger room of the railway vehicle; and a passenger room floor which is hung at the second end of the floor framework and / or the vertical handrail so as to separate the passenger room floor from the vehicle body floor. According to the interior assembly of the railway vehicle, the passenger room floor and the equipment under the vehicle can be isolated from each other, noise generated in the running process of the equipment under the vehicle is prevented from being transmitted into a passenger room through the passenger room floor, and the noise in the passenger room is reduced. The transverse span of the guest room floor can be reduced, and the rigidity requirement of the guest room floor is met. The vertical handrail can be supported and fixed, and the structural strength of the passenger room floor can be enhanced. The passenger room floor, the floor framework and the vertical handrail can be assembled and formed under the vehicle and then integrally installed on the vehicle body after being assembled, and the vehicle body assembling efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a vehicle body, a rail vehicle and an interior assembly thereof. Background technique [0002] At present, the car body and interior structures such as the floor of the passenger compartment, interior wall panels, roof panels, etc., are respectively installed on the car body through mounting seats and other structures, but due to the use of mounting seats, there are installation joints between the structures, which is not conducive to interior partitions sound design. [0003] For the passenger compartment floor, the vibration of the bogie and the equipment under the vehicle is transmitted to the car body, and then transmitted to the interior floor through the floor installation structure, and then radiates noise into the vehicle; during the noise reduction design process of rail vehicles, the passenger compartment floor can be reduced by the floor The vibrator is installe...

AI Technical Summary

Problems solved by technology

[0002] At present, the car body and interior structures such as the floor of the passenger compartment, interior wall panels, roof panels, etc., are respectively installed on the car body through mounting seats and other structures. However, due to the use of mounting seats, there are installation joints between the structures, which is not conducive to interior partition sound design

[0003] For the passenger compartment floor, the vibration of the bogie and the equipment under the vehicle is transmitted to the car body, and then transmitted to the interior floor through the floor installation structure, and then radiates noise to the interior of the vehicle; during the noise reduction design process of rail vehicles, the passenger compartment floor can be reduced The vibrator is installed on the floor of the car body to reduce the transmission of car body vibration to the inside of the car, but this method cannot fundamentally solve the problem of floor vibration transmission
