Abstract

An embodiment of the present application provides a rail train, including: a semi-closed air duct, the air duct includes the top of the air duct and the sides of the air duct; the top of the air duct is fixed to the inner roof of the train body, and the The side parts of the air duct are connected to both sides of the top of the air duct and protrude downward; the large side roof is fixed with the car body as a part of the train roof, and the large side roof is sealed on the air duct. The bottom end of the side part of the channel forms an air circulation channel with the air channel. The rail train of the embodiment of the present application solves the technical problem that the roof and air duct of the rail train are not conducive to the overall weight reduction of the rail train.

Description

technical field [0001] The present application relates to the technical field of electric locomotives, in particular, to a rail train. Background technique [0002] The roof and the air duct of the rail train are independent, designed separately, and heavy, which is not conducive to the overall weight loss of the rail train. [0003] Therefore, the roof and the air duct of the rail train are not conducive to the overall weight reduction of the rail train, which is a technical problem that those skilled in the art urgently need to solve. [0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the application and therefore it may contain information that does not form the prior art that is already known in the art to a person of ordinary skill in the art. Contents of the invention [0005] An embodiment of the present application provides a rail train to solve the technical problem that the roof and a...
