Totally-closed folding shed type external windshield

Abstract

The invention discloses a totally-closed folding shed type external windshield, which is used for connection between the ends of two high-speed railway vehicles and comprises two mounting frames. The two mounting frames are fixed to the ends of the two vehicles and closed along the outlines of the vehicle ends, a folding shed component is fixed between the two mounting frames, the outer face of each mounting frame is provided with an inner groove, a sealing groove is formed by each inner groove and the corresponding vehicle end face after the mounting frames are fixed to the ends of the vehicles, and a sealing strip is arranged in each sealing groove. The mounting frames of the external windshield are directly connected with the ends of the two vehicles, a gap between the end faces of two adjacent vehicles can be eliminated by means of the totally-closed structure, complex displacement of vehicles can be met by means of the foldable and retractable folding shed structure, a smoother section of the windshield is guaranteed in different road conditions, and accordingly air flow can flow along the external windshield smoothly, operating resistance, micro-pressure waves and pneumatic noise of a train can be effectively reduced, and comfortableness can be improved for passengers.

Description

technical field [0001] The invention relates to the technical field of rail passenger cars, in particular to a fully enclosed bellows-type outer windshield used for connecting high-speed rail passenger cars. Background technique [0002] With the continuous improvement of the operating speed of domestic CRH high-speed trains, it is more and more important to further reduce the running resistance of trains and improve the stability of train running. At present, the ends of the CRH high-speed trains in operation mostly use fairings to reduce running resistance and improve running stability, but the fairings are installed on both sides or top of the end of the train in sections. Afterwards, there is still a large gap between the ends of the two train vehicles and between the fairings, which will still cause great running resistance and instability when the train is running. Therefore, based on the current situation, in the two train vehicles There is an urgent need to install ...

Problems solved by technology

At present, the ends of the CRH high-speed trains in operation mostly use fairings to reduce running resistance and improve running stability, but the fairings are installed on both sides or top of the end of the train in sections. Afterwards, there is still a large gap between the ends of the two train vehicles and between the fairings, which will still cause great running resistance and instability when the train is running. Therefore, based on the current situation, in the two train vehicles There is an urgent need to install a new product to replace the fairing between the ends of the train, so as to further reduce the running resistance and noise of the train, improve the stability of the train running and the comfort of the passengers
