Vehicle connection portion noise reduction and protection device of high-speed motor train unit

Abstract

The invention provides a vehicle connection portion noise reduction and protection device of a high-speed motor train unit, wherein the device is arranged at the periphery of the train windshield of the high-speed motor train unit along a windshield circumferential position. The device comprises a pair of device installation seats and a pair of flexible elastic absorbers, wherein the elastic absorbers are butted with each other and are symmetrically distributed along the contact surfaces of the elastic absorbers; fracture surface external outlines of the elastic absorbers are protruded to theexternal side of a vehicle; the pair of device installation seats are directly or indirectly fixed at the end parts of front and back sections of the vehicle respectively; and the elastic absorbers are fixed on the installation seats. The device has the advantages of restraining the air power passing through the external side of the train windshield, reducing the noise in the train, improving theriding comfortableness of passengers, protecting the train windshield and prolonging the service life of the windshield.

Description

technical field [0001] The invention relates to a high-speed train set, in particular to a noise reduction and protection device for a vehicle connection part of a high-speed train set. Background technique [0002] The train windshield is an important part of a railway passenger car. It acts as a movable connection between two cars and is also a passage for passengers from one car to another. In addition to ensuring the safety of passengers, the train windshield also has longitudinal expansion and contraction performance, which can improve the stability of train operation. When the vehicle is in any relative position, the windshield remains in close contact to prevent wind, sand, rain, snow, dust, etc. from entering the vehicle. The windshield plays a very important role in the connection and operation of the train. [0003] The windshield of the train is set at the ends of two adjacent vehicles, such as figure 1 and figure 2 As shown, it includes a pair of windshield ...

AI Technical Summary

Problems solved by technology

[0004] In addition, when the train is running at high speed, the aerodynamic force generated outside the vehicle will cause a large air pressure difference between the outside and inside of the windshield capsule, which will easily cause the windshield capsule to flip inward and interfere with the surrounding parts, reducing the service life of the windshield
