본 고안은 철도차량용 도어(door)의 방음장치에 관한 것으로, 특히 철도차량의 차체와 도어의 접촉부위에 부러쉬를 장착하여 철도차량 외부에서 발생되는 소음으로부터 철도차량 내부를 보호하기 위한 장치에 관한 것이다.The present invention relates to a soundproofing device of a door for a railroad car, and more particularly, to a device for protecting the inside of a railroad car from noise generated outside of the railroad car by attaching a brush to a contact portion between the door and the door of the railroad car. .

일반적으로, 철도차량은 고속으로 운행됨에 따라 차체벽과 공기의 마찰에 의해 마찰소음이 크게 발생되고, 이 소음이 차량내부로 전달되어져 승객에게 불편함을 줄뿐만 아니라 승차감도 저하되는 문제점이 있다.In general, as the railroad vehicle operates at a high speed, friction noise is greatly generated by friction between the vehicle body wall and the air, and the noise is transmitted to the inside of the vehicle, which not only inconveniences the passenger but also reduces the riding comfort.

이러한 문제점을 종래의 철도차량용 도어를 예시하여 설명하면 다음과 같다. 제2도는 종래의 철도차량용 도어의 개략적인 단면도로서, 철도차량용 도어(10)의 상단 일부가 차체(20)와 점검커버(30) 사이에 끼워지고, 상기차체(20)와 점검커버(30) 사이에는 도어(10)를 개폐시키기 위한 도어구동부(40)가 구비되는 한편, 도어(10)를 개폐시키기 위한 도어구동부(40)가 구비되는 한편, 도어(10)의 하단내부에는 슬라이딩용 몰드(50)가 구비되며, 이 몰드(50)에 의해 도어프레임(60) 상부에 형성된 도어레일(70)을 따라 도어(10)가 슬라이딩하도록 된 구조로 되어 있다.This problem will be described below by way of example for a conventional railway vehicle door. 2 is a schematic cross-sectional view of a door for a conventional railway vehicle, a part of the upper end of the railway vehicle door 10 is sandwiched between the vehicle body 20 and the inspection cover 30, the vehicle body 20 and the inspection cover 30 A door driver 40 is provided between the door 10 to open and close the door 10, and a door driver 40 is provided to open and close the door 10, while a sliding mold ( 50 is provided and has a structure in which the door 10 slides along the door rail 70 formed on the door frame 60 by the mold 50.

그러나, 이와 같은 종래의 철도차량용 도어는 철도차량 외부에서 발생된 소음이 도어(10)의 외측상단부와 차체(20) 사이의 틈새 및 도어(10)의 내측상단부와 점검커버(30) 사이의 틈새를 통하여 철도차량 내부로 전파됨과 더불어, 도어(10)의 하단부에 구비된 몰드(50)는 도어레일(70)을 따라 슬라이딩되기 때문에 상기 몰드(50)와 도어레일(70)의 접촉부위가 완전히 밀폐되지 않아 철도차량 외부에서 발생된 소음이 상기 몰드와 도어레일 사이의 틈새를 통하여 철도차량 내부로 전파되는 문제점이 있었다.However, in the conventional railroad car door, the noise generated outside the railroad car is a gap between the outer upper end of the door 10 and the vehicle body 20 and a gap between the inner upper end of the door 10 and the inspection cover 30. In addition to being propagated into the railway vehicle through, the mold 50 provided at the lower end of the door 10 is slid along the door rail 70, so that the contact portion between the mold 50 and the door rail 70 is completely There is a problem that the noise generated from the outside of the railway vehicle is not sealed and propagates inside the railway vehicle through the gap between the mold and the door rail.

이에, 본 고안은 상기한 바와 같은 제 문제점을 해소시키기 위해 철도차량용 도어의 좌측상단부와 차체 사이의 틈새와 도어의 내측상단부와 점검커버사이의 틈새 및 도어의 하단내부에 구비된 몰드와 도어레일 사이의 틈새를 밀폐시켜 철도차량 외부에서 발생된 소음이 철도차량 내부로 전파되지 못하도록 한 방음장치를 제공하는데 그 목적이 있다.Accordingly, the present invention provides a clearance between the upper left end of the railway vehicle door and the vehicle body, the clearance between the inner upper end of the door and the inspection cover, and the mold and the door rail provided in the lower end of the door to solve the problems as described above. The purpose of the present invention is to provide a soundproofing device that seals the gap between and prevents noise generated from outside the railway vehicle from propagating inside the railway vehicle.
