Variable-section bullet train

Abstract

The invention discloses a variable-section bullet train, which comprises a train body. The train body comprises a middle area identical in section size and narrowing areas at the front and and / or therear end of the middle area. The narrowing areas are connected with the middle area, and the section of each narrowing area is gradually narrowed towards a direction away from the middle area. By thevariable-section bullet train, the requirement of small limit of the bullet train can be met, and great performance of the train passing through small-curve-radius rails is achieved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a variable-section EMU car body. Background technique [0002] At present, the section structure of the car body of the EMU is the same in the length direction. However, due to the limit limit in many places, for the comfort of the car body, the car body section needs to be enlarged. If the car body is made wider, when the car turns When the radius curve is too small, it is bound to interfere with the limit. That is to say, in the prior art, the traditional vehicle body structure cannot satisfy the above-mentioned vehicles with large cross-section and small boundary. Contents of the invention [0003] The object of the present invention is to provide a variable-section EMU car body, which can meet the small limit requirement of the EMU, so that the vehicle has the characteristics of strong ability to pass through a small radius of curvature. [0004] In order to achieve...
