Description

철도차량 연결기의 완충구조Shock Absorbing Structure of Railway Vehicle Coupler

본 고안은 철도차량 연결기의 완충구조에 관한 것으로, 상세히는 철도차량의 운행, 출발 및 정지시 발생하는 인장, 압축력을 완화시켜 차량의 소음과 진동을 감소시킴과 아울러 연결기의 정위치 유지를 도모하여 차량간의 연결작업을 손쉽게 할 수 있도록 한 것이다.The present invention relates to a shock absorbing structure of a railway vehicle coupler, and in detail, to reduce the noise and vibration of the vehicle by reducing the tension and compression force generated during the operation, start and stop of the railway vehicle, and to maintain the position of the connector. It is to make the connection work between cars easy.

철도차량간의 연결을 위하여 사용되는 연결기는 통상 병렬식 연결기와 밀착식 연결기의 2종류가 있으며, 전철이나 지하철 등의 전동차량에는 후술한 밀착식 연결기를 주로 사용하고 있다.There are usually two types of couplers used for the connection between railroad cars, parallel couplers and close couplers, and the close couplers described below are mainly used for electric vehicles such as trains and subways.

상기한 종래의 밀착식 연결기는 통상 암수연결기로 각각 이루어지며, 이는 공히 선단에 돌출부와 밀착부가 형성되어 상호 일치되면서 결합됨과 동시에 각각의 암수연결기에 내장된 반달형의 로크가 서로 맞물리도록 되어 있고, 연결기의 후단에는 연결축이 직접 힌지결합되는 구조로 이루어져 있으므로, 다른 연결기와 결합되어 있지 않을 경우에는 연결기 선단이 좌, 우 임의의 각도로 위치하게 됨과 아울러 자체의 하중에 의하여 하방으로의 처짐이 발생하게 되므로 차량간 연결시 상호 정확한 위치를 맞추어 주어야 하며 차량간 연결작업에 인력이 투입되어야 하는 폐단이 있었고, 연결작업중 각종 안전사고가 발생할 우려가 있었으며, 연결후 차량사이에 걸리는 압축, 견인하중에 의하여 소음이 발생하게 됨과 아울러 충격이 차량에 전해지게 되어 승객이 불안을 느끼게 되고 승차감이 떨어지게 되는 주요인이 되어 왔었다.The conventional close contactor is usually made of a male and female connector, which is formed so that the protrusions and the close contact are formed at the front end and coincide with each other, and at the same time, the half-moon locks embedded in the male and female connectors are engaged with each other. Since the rear end has a structure in which the connecting shaft is hinged directly, when it is not coupled with other connectors, the tip of the connector is positioned at an arbitrary angle left and right, and sag is generated downward by its own load. When connecting between vehicles, it was necessary to match each other precisely, and there was a need to put manpower into the connection work between cars, and there was a risk of various safety accidents during the connection work. In addition to the impact It had been the main reason that customers feel the anxiety and the ride apart.

본 고안은 상기한 종래의 문제점을 감안하여 안출된 것으로, 본 고안의 목적은 철도차량의 운행, 출발 및 정지시 발생하는 인장·압축력을 완화시키므로써 차량의 소음과 진동을 감소시키고, 차량간 연결시 발생하는 충격도 효과적으로 흡수할 수 있는 연결기구조를 제공함과 아울러, 연결기가 항상 정위치에 있도록 하므로써 연결작업을 간편하게 할 수 있도록 하는 수단을 제공하는데 있는 것이다.The present invention is conceived in view of the above-described conventional problems, the object of the present invention is to reduce the noise and vibration of the vehicle by reducing the tension and compression force generated during the operation, start and stop of the railway vehicle, and the connection between vehicles In addition to providing a connector structure that can effectively absorb the shock generated during the time, and to provide a means for simplifying the connection work by ensuring that the connector is always in place.

이와 같은 목적을 달성하기 위하여 본 고안은 연결기의 몸체 후부와 차량의 프레임에 고정되는 브라켓 사이에 고무재의 완충부재를 2중으로 설치하여 완충부재의 신축동작에 의하여 차량의 압축·인장하중을 흡수할 수 있도록 하고, 연결기 몸체의 양측에는 탄성력을 갖는 수직지지대를 설치하여 차량의 프레임에 지지되도록 하므로써 연결기가 항상 정위치를 유지할 수 있도록 한 철도차량 연결기의 완충구조를 제공한 것이다.In order to achieve the above object, the present invention can absorb the compression and tensile load of a vehicle by installing a double cushioning member of rubber material between the rear body of the connector and the bracket fixed to the frame of the vehicle. In order to support the frame of the vehicle by installing a vertical support having elastic force on both sides of the connector body to provide a shock absorbing structure of the railway vehicle coupler to ensure that the connector is always in place.

And a half-moon-type lock 16 is provided, the rear end of the body 10, the connecting member 20 is inserted into the shaft 22 of a predetermined length to protrude rearward fixing means 28 such as bolts. And a pair of donut buffer members 30 and 30 'are fitted to the outside of the shaft 22 fitted to the connecting member 20, and the frame F is provided between the buffer members 30 and 30'. ) Is fixed to the fixing bracket 40, the rear end of the shaft (22) has a structure that is fitted by the fixing nut (44) is inserted into the release preventing member (42).

상기 고정너트(44)의 후단에는 이의 풀림을 방지하기 위하여 잠금구(46)가 축(22)후면의 요홈(24)에 끼워진 상태로 보울트 등의 고정수단(26)으로 체결되어 차량에 설치된 상태에서 차량의 진동이나 유동에 의하여 풀리게 되는 것을 방지할 수 있도록 한 것이다.The lock nut 46 is fastened to the rear end of the fixing nut 44 by a fixing means 26 such as a bolt in a state of being fitted into the groove 24 on the rear of the shaft 22 to prevent its loosening. In order to prevent the vehicle from being released by vibration or flow.

또, 본 고안은 몸체(10)의 후부 양측에 수직지지대(50,50')를 설치한 것으로, 이 수직지지대(50,50')는 고무재를 원통형상으로 제작하되, 그 상·하단이 도 3 및 도 4에 도시한 바와 같이, 몸체(10)의 후부 양측에 돌출형성된 브라켓(18)과 프레임(F)에 각각 고정수단(28)으로 고정되어 지지되도록 하므로써 수직지지대(50,50')가 완충기능을 발휘하여 연결기 몸체(10)를 소정범위내에서 상·하, 좌·우로 유동가능하도록 함과 동시에 항시 정위치에 안정적으로 위치할 수 있도록 한 것이다.In addition, the present invention is to install the vertical support (50, 50 ') on both sides of the rear portion of the body 10, the vertical support (50, 50') is made of a rubber material in a cylindrical shape, the upper and lower ends 3 and 4, the vertical support (50, 50 ') by being fixed to the bracket (18) and the frame (F) protruding on both sides of the rear portion of the body (10) by fixing means (28), respectively, to be supported. By exerting a shock absorbing function, the connector body 10 can be moved up, down, left and right within a predetermined range, and at the same time, it can be stably positioned at the right position.

상기 한쌍의 완충부재(30,30')는 중간부가 관통된 도우넛형으로 이루어져 축(22)에 끼워진 고정브라켓(40)의 내외측에 각각 위치하게 되는 것으로, 차량간 압축력이 작용할 경우에는 고정브라켓(40)전방의 완충부재(30)가 납작하게 수축변형되면서 압축력을 흡수하게 되는 것이며, 차량간 인장력이 작용할 경우에는 고정브라켓(40) 후방의 완충부재(30')가 납작하게 수축변형되면서 인장력을 흡수하게 되므로써 진동과 충격을 상쇄시키게 되는 것이다.The pair of shock absorbing members 30 and 30 'are formed in a donut shape with a penetrating middle portion, respectively, and are positioned at the inside and outside of the fixing bracket 40 fitted to the shaft 22. When the compression force between the vehicles is applied, the fixing bracket (40) The front cushion member 30 is to shrink the compression deformation flat to absorb the compressive force, when the tension force between the vehicle acts as a shock-absorbing member (30 ') of the fixed bracket 40 rear shrinkage flat tension By absorbing the vibrations to counteract the vibration and shock.

또한, 상기 수직지지대(50,50')는 고무재로 이루어져 연결기 몸체(10)의 하중을 받쳐주게 되므로 연결기 몸체(10)가 지나치게 하방으로 처지게 되는 것을 방지함과 아울러 차량간 압축력 또는 인장력이 가해질 때 탄성적으로 변형되면서 연결기의 전·후방향으로의 유동과 좌·우방향으로의 유동을 소정범위내에서 보장해주게 되므로써 암수연결기간의 결합시 정확한 위치가 유지되어 결합동작이 원활히 이루어지게 되는 것이다.In addition, since the vertical support (50, 50 ') is made of a rubber material to support the load of the connector body 10, the connector body 10 is prevented from sagging excessively downward and the compression or tension between the vehicle is When applied, it is elastically deformed and ensures the flow in the front and rear direction of the connector and the flow in the left and right directions within a predetermined range, so that the correct position is maintained during the coupling of the male and female connection periods so that the coupling operation is smoothly performed. will be.

또한, 본 고안에서는 금속과 금속이 연결되는 부분 즉, 연결기 몸체(10)와 고정브라켓(40)사이에는 직접적인 접촉이 없도록 완충부재(30,30')가 개재되어 있으므로 슬랙(slack)이 발생하지 않게 되어 금속간의 마찰음이 발생하지 않게 되는 것이며, 이에 따라 차량주행시 발생하게 되는 소음을 줄여 승차감향상을 도모할 수 있는 것이다.In addition, in the present invention, since the shock absorbing members 30 and 30 'are interposed so that the metal and the metal are connected to each other, that is, the connector body 10 and the fixing bracket 40, there is no slack. Therefore, the friction noise between the metals does not occur, thereby reducing the noise generated when driving the vehicle, thereby improving the riding comfort.

이상 설명한 바와 같이 본 고안은 연결기의 몸체후부에 설치된 한쌍의 고무재로 된 도우넛형의 완충부재가 차량간에 걸리는 압축력이나 인장력에 따라 선택적으로 수축되면서 압축력과 인장력을 흡수하게 되므로 진동을 감소시킬 수 있음과 아울러 연결기와 브라켓은 직접 접촉되지 아니하고 완충부재가 개재되어 있으므로 금속간의 마찰음이 발생하지 않아 승차감이 향상되며, 연결기 몸체의 좌·우 양측에 설치된 수직지지대에 의하여 연결기가 항시 정위치에 있게 되므로 차량간 연결작업이 용이하게 되는 등의 유용한 효과를 갖는다.As described above, the present invention can reduce vibrations by absorbing the compressive and tensile forces by selectively contracting the donut-type buffer member made of a pair of rubber materials installed at the rear of the connector, depending on the compressive or tensile force applied between the vehicles. In addition, the connector and the bracket are not in direct contact, and the cushioning member is interposed, so that the frictional sound between the metals does not occur, and the riding comfort is improved. It has a useful effect such as easy connection between the work.
