Stainless steel vehicle body of rail vehicle

Abstract

The invention discloses a stainless steel vehicle body of a rail vehicle. The stainless steel vehicle body comprises a vehicle roof, a side wall, an end wall, an under frame and a cab, wherein the vehicle roof comprises top cover boundary beams which are positioned at two sides and a top cover camber beam which is connected with the top cover boundary beams; side top plates are arranged at the outer sides of the top cover boundary beams in a covering way; side roof connecting beams are fixedly connected to the lower parts of the side top plates; the cross sections of the top cover boundary beams are C-shaped; boundary beam reinforcing upright posts are arranged in C-shaped cavities; sealing plates which are fixedly connected with the top cover boundary beams are arranged in C-shaped openings. When the stainless steel vehicle body of the rail vehicle, provided by the invention, is used, sealed cavity structures are formed through the matching of the sealing plates and the top cover boundary beams, so that the strength of the region can be obviously increased, the bearing function of the top cover boundary beams in the longitudinal direction of the vehicle body is enhanced, and the capacity of resisting vertical deformation of the vehicle body is increased; meanwhile, by combining the structure improvement of the top cover boundary beams, a connecting way of the top cover boundary beams and the side wall is correspondingly improved, the connecting reliability and the attractiveness are increased through the arrangement of the side roof connecting beams, and the whole intensity of the vehicle body is further increased.

Description

technical field

[0001] The invention relates to the technical field of rail vehicles, and more specifically, relates to a stainless steel body of a rail vehicle. Background technique

[0002] With the increasingly serious problems of traffic congestion, travel inconvenience, and environmental pollution, the concept of giving priority to the development of rail transit has been recognized by more and more people. Rail transit has a large transportation capacity and can transport a large passenger flow in a short time; it has high punctuality and can make passengers reach their destinations faster, shortening the travel time; less environmental pollution, due to most Electric traction is used, which has little air pollution.

[0003] Rail vehicles are an important part of rail transportation. The car body is the main load-bearing structure of the rail vehicle, which is generally in the shape of a thin-walled cylinder, and specifically includes structures such as the roof, si...
