An inflatable outer windshield for an EMU

Abstract

The invention discloses an inflatable type outer windscreen of a motor train unit. The inflatable type outer windscreen of the motor train unit is characterized in that the periphery of the end face of a front car (1) is fixedly connected with an inflatable integral-ring-shaped rubber air bag (3), the periphery of the end face of a rear car (2) is also fixedly connected with an inflatable integral-ring-shaped rubber air bag (3), and the opposite surfaces of the two inflatable rubber air bags (3) are tightly attached to each other. The inflatable type outer windscreen of the motor train unit has good air tightness, heat-shielding performance, sound insulation performance and rainproof performance, small aerodynamic resistance and good curve passage capacity, and can provide a safer and more comfortable walking-through environment for passengers, and provide more effective protection for car flexible connection devices.

Description

technical field [0001] The invention relates to a windshield at the flexible joint of train vehicles, in particular to an inflatable outer windshield between train vehicles. Background technique [0002] Soft connections are usually used between train vehicles, which allow the running vehicles to have a certain relative movement at the connection. In order to enable passengers to walk safely and comfortably through the connection between vehicles, and to protect the soft connection device from rain, snow, wind, and sand, it is necessary to set an inner windshield and an outer windshield at the soft connection of the vehicle. As far as the external windshield is concerned, it needs to have good rainproof performance and the ability to withstand wind loads, and can shelter from wind and rain; it must also have certain heat insulation performance and sound insulation performance; The aerodynamic resistance should be as small as possible, and it should have a certain ability to...

AI Technical Summary

Problems solved by technology

These outer windshields are not shielded at the lower part of the end face of the car body, and do not form a closed space; thus they do not have airtightness, poor heat insulation and sound insulation

The gap between the sunscreen and rainproof board and the horizontal rubber bag is large, and there is also a gap between the horizontal rubber bag and the vertical rubber bag, and its rainproof performance is not ideal; The gap between the rubber bladders and the uneven transition also make the aerodynamic resistance large
