Problems solved by technology

It can be seen that due to the vortex accumulation formed by the crosswind on the side of the car body, it is easy to cause the car body to roll over, which seriously endangers driving safety.

Abstract

The invention provides a railway vehicle body and a railway vehicle. The railway vehicle body and the railway vehicle comprise an underframe, lateral walls and a top plate. At least two rim strips are arranged on the top plate and at least two rim strips are arranged along the vehicle body in a longitudinal mode. Each rim strip comprises a longilineal rim strip body and a connective pin shaft, wherein the connective pin shaft is vertically arranged. The rim strip body is hinged on the top plate through the pin shaft; a first spacing distance is formed between two adjacent rim strips. The railway vehicle body can be used for reducing vortex gathers formed by lateral wind on a leeward side of the vehicle body in the railway vehicle operating process. Tumbling tensile force formed by vortexes on the vehicle body also can be reduced, so that possibility of side turning can be effectively reduced in the railway vehicle operation and driving safety is observably improved.

Description

technical field [0001] The invention relates to a railway vehicle manufacturing technology, in particular to a railway vehicle body and a railway vehicle. Background technique [0002] During the operation of the railway vehicle, it is always subjected to the resistance generated by the air. For the railway vehicle running along the rails, the resistance wind formed by the air flow can be divided into the wind blowing from the front of the railway vehicle and the wind from the side of the railway vehicle. The side wind blowing in the direction (perpendicular to the running direction of the railway vehicle), and the effect of the side wind on the car body is the main factor affecting the operation of the train. [0003] figure 1 It is a schematic diagram of the crosswind flow direction of the railway vehicle body in the prior art; figure 2 for figure 1 Schematic diagram of the force state of the middle car body under crosswind conditions; figure 1 and figure 2 As shown...
