External windshield and rail vehicle with same

Abstract

The invention discloses an external windshield. The external windshield comprises a rubber bag and two mounting bases which are arranged in parallel; each mounting base comprises a strip-shaped body and a first vertical part and a second vertical part which are perpendicular to the strip-shaped body and are arranged in parallel, wherein a groove is formed between the first vertical part and the second vertical part; the two side edges of the rubber bag are inserted into grooves of the two parallel mounting bases and fixed in the grooves. The external windshield has the advantages of being higher in structural strength, better in wear resistance, easy and convenient to mount and higher in maintainability.

Description

technical field [0001] The invention belongs to rail vehicles, and in particular relates to an outer windshield and a rail vehicle thereof. Background technique [0002] The outer windshield is a standard configuration for medium and high-speed EMUs. It can improve the aerodynamic performance of the train, enhance the visual effect of the end of the train, reduce the gap between the end of the train and the platform, and reduce potential safety hazards. Therefore, it is increasingly used in various A rail vehicle. [0003] Chinese patent CN201410796439.X discloses an EMU and its outer windshield, the outer windshield is installed on the end wall of the EMU car body, and the outer windshield is an all-inclusive rubber outer windshield to be in contact with the outer windshield of the adjacent car body , and the outer windshield is ring-shaped to be arranged around the end wall of the vehicle body; the outer end surface of the outer windshield is arc-shaped so that two adjace...

AI Technical Summary

Problems solved by technology

[0006] 1. The windshield installation structure design in the prior art makes installation inconvenient, and opening process holes will lead to a reduction in the structural strength of the windshield

[0007] 2. The outer surface of the windshield is generally sprayed with paint to protect the windshield and make it look beautiful, but the paint ages quickly. There is friction after the windshield of the front compartment and the windshield of the rear compartment touch each other. The surface of the paint is not wear-resistant and needs to be replaced regularly, which increases maintenance costs and difficulty

[0008] 3. Due to the wider operating environment of rail vehicles, there may be smaller curve radii in line conditions, and the extrusion friction conditions of the outer windshield are more severe. It is difficult for the outer windshield of the existing technology to meet the needs of small-radius curves

[0009] 4. The mounting seats of the outer windshield in the prior art need to be fixed by beams, which increases the weight of the outer windshield, which is not conducive to the light weight of rail vehicles
