Problems solved by technology

[0005] The purpose of the present invention is to provide a car body floor structure and a rail vehicle with the same structure, to solve the problem that the car body floor in the prior art is usually integral, and it is necessary to add a plurality of beams to support the integral car body floor. Thereby, the weight of the car body is greatly increased and the car body floor is usually fixed by welding, so that the whole car body floor is prone to deformation.

Abstract

The invention relates to the technical field of railway vehicles, and discloses a vehicle body floor structure and a railway vehicle with the vehicle body floor structure. The vehicle floor structurecomprises a floor frame, a floor body, and a plurality of support beams, wherein the floor body is detachably mounted on the floor frame, the floor body comprises a plurality of floor units, and adjacent floor units are detachably connected; each of the support beams is arranged on the floor frame and used for supporting the floor body, wherein one of the support beams is arranged between every two of the floor units. The vehicle body floor structure has the advantages of being modularized, detachable, light in weight, and low in welding quantity.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a vehicle body floor structure and a rail vehicle with the structure. Background technique [0002] At present, the floor of the rail vehicle body structure is mainly composed of aluminum alloy profiles and stainless steel plates. The interface connection mode between aluminum alloy profiles and stainless steel plates and the car body structure is mainly welding. However, welding will directly lead to the deformation of the aluminum alloy profile and stainless steel plate, that is, the overall shrinkage of the aluminum alloy profile and stainless steel plate. In view of this situation, a special process method is required to adjust the composition of the floor. Adjustment, however, is completely inconsistent with the trend of energy conservation and emission reduction. [0003] In addition, the existing floor of the car body is generally integral, that is, in order to mee...
