본 고안은 철도차량용 차륜과 레일 사이의 접착력 증가장치에 관한 것으로서, 차륜의 주위에 작동용 에어실린더와 로드 및 링크로서 연동 설치된 지지판에 마모성 점착슈를 고정 부착 설치하여, 차량의 브레이크 작동시 상기 마모성 점착슈가 차륜의 전면과 접촉토록 하고 그 사이에서 발생하는 마찰력에 의하여 점착슈의 주성분인 점착미립자가 레일상에 낙하 공급되므로서, 진행하는 차륜의 표면과 레일 사이에 점착력을 증가시켜 차륜과 레일 사이의 슬립(slip)과 스키드(skid) 현상을 방지토록 함에 그 목적이 있는 것이다.The present invention relates to a device for increasing adhesion between a wheel and a rail for a railroad vehicle, wherein the wearable adhesive shoe is fixedly installed on a support plate interlocked as an operating air cylinder, a rod, and a link around the wheel, and the wearability is applied when the brake of the vehicle is operated. The adhesive shoe is brought into contact with the front surface of the wheel, and the adhesion particles, which are the main components of the adhesive shoe, are dropped onto the rails by the frictional force generated therebetween, increasing the adhesive force between the surface of the wheel and the rail where the wheels are running. The purpose is to prevent slip and skid phenomenon.
종전의 철도의 동력차 즉, 전기동차, 디젤동차, 디젤기관차등은 우천시나 강설시 선로(레일)의 상태가 나쁜 상태에서 차륜에 제동을 체결하게 되면 차륜이 레일상에서 공전과 미끄러지는 슬립 및 스키드에 의한 차륜의 편마모 현상이 발생하여 덜컹거리게 됨에 따라 승차감이 좋지 못하고 이를 해결하기 위하여는 차륜을 깎아내거나 또는 바꾸어야 하는 일이 종종 일어나며, 주행하다 급정차할 경우 규정된 안전제동거리(약 600m)를 넘어 정차하게 되어 사고가 발생하는 사례가 많았던 것이다. 그러므로, 종래에는 열차를 정지 또는 감속시키려면 별도의 디스크 브레이크를 이용하여 차륜회전을 제지토록 하면서, 차륜과 레일 사이의 점착력 증가를 위하여 모래박스를 차내에 탑제하여 필요시 레일위에 모래를 뿌려 점착력을 증가시키는 방법을 사용하였던 것이다.Power trains of conventional railways, such as electric cars, diesel cars, and diesel locomotives, are applied to slips and skids that slip and slip on rails when brakes are applied to the wheels in bad weather or when the rails are in bad condition. As a result of uneven wear of wheels, it is not easy to ride, and it is often necessary to scrape or change the wheels to solve them, and when driving suddenly, it exceeds the prescribed safety braking distance (about 600m). There were many cases of accidents caused by stopping. Therefore, in order to stop or decelerate a train, a separate disc brake is used to restrain the wheel rotation, and a sand box is mounted in the vehicle to increase the adhesive force between the wheel and the rail, and sand is applied on the rail if necessary to apply the adhesive force. The method of increasing was used.
따라서, 수시로 모래를 보충하여야 하며, 때로는 모래통로가 메워져 작동이 되지 않게 되어 제기농을 다하지 못하므로써 안전사고에도 많은 문제점이 있었다.Therefore, the sand must be replenished from time to time, and sometimes the sand passages are filled, so there is a lot of problems in safety accidents because it is not able to run the raised farm.
본 고안은 이상의 문제점들을 감안하여 통상의 디스크 브레이크가 작동할 때와 동시 그와 연동되도록 설치된 슈지지판의 소결합금제 점착슈가 차륜 전면과 접속하도록 하여, 점착미립자가 차륜이 지나갈 레일상에 떨어지도록 하므로써, 차륜과 레일 사이에 점착력이 증가되면서 슬립과 스키드를 예방할 수 있도록 안출된 것으로, 이를 첨부도면에 의해 상술하면 다음과 같다.In view of the above problems, the present invention allows the small-bonded gluing shoe of the shoe support plate installed to interlock with the normal disk brake at the same time as the normal disk brake operates so that the gluing fine shoe can be connected to the front of the wheel so that the tack fine particles fall on the rail through which the wheel will pass. In order to prevent slip and skid while increasing the adhesive force between the wheel and the rail, it will be described in detail by the accompanying drawings.
본 고안은 대차후레임부 에에어실린더(1)를 부설하고, 에어실린더(1)에 로드(2)와 링크(3)를 이용하여 차륜(5)의 전방에 슈지지판(4)을 설치하여, 기존의 디스크 브레이크의 작동시 슈지지판(4)이 차륜(5)쪽으로 이동되도록 하고, 슈지지판(4) 내측면에는 점착슈(6)를 고정 설치하므로서, 브레이크 작동시 그 내측면이 차륜(5)의 전방 표면과 접촉 마모되면서 점착슈(6)를 조성하고 있는 점착미립자가 차륜의 원주속도에 의해 차륜과 레일 사이로 공급되도록 한 것이다(도면 제 1 도 참조).According to the present invention, the air frame 1 of the bogie frame part is installed, and the shoe support plate 4 is installed in front of the wheel 5 by using the rod 2 and the link 3 on the air cylinder 1, When the disc brake is operated, the shoe support plate 4 is moved toward the wheel 5, and the shoe support plate 4 is fixed to the inner surface of the shoe support plate 4 so that the inner surface thereof is the wheel 5 when the brake is operated. The adhesive particulates constituting the adhesive shoe 6 while contacting and worn with the front surface of the c) are supplied between the wheel and the rail by the circumferential speed of the wheel (see FIG.
여기에서, 점착슈(6)는 소결합금 성형으로 제조되는 것으로 이의 조성물은 철 또는 래진을 주원료로 하면서 동(5-10%), 니켈(5-7%), 금속산화물(10-20%)를 배합하는 것이 효과적이며, 도며 제 5(a)도, 제 5(b)도, 제 5(c)도에서와 같이 시험도표에 의하여 상기와 같은 소결합금은 주철과 비교하여 마모율에 대비한 수명이 5배에 가깝고, 동일압축력에 의한 점착계수가 월등히 높은 것을 알수 있는 것이다.Here, the adhesive shoe (6) is produced by small alloy molding, the composition of which is made of iron or resin as the main raw material copper (5-10%), nickel (5-7%), metal oxide (10-20%) It is effective to formulate and, as shown in Figs. 5 (a), 5 (b) and 5 (c), according to the test chart, the above-mentioned small-bonded alloys have a lifespan compared to the wear rate compared to cast iron. It is close to 5 times, and it can be seen that the adhesion coefficient due to the same compressive force is extremely high.
본 고안은 장치의 구성은 에어실린더(1)의 좌측에는 공기배관(1-2)을 중간에는 기압부(1-3)를, 우측에는 연결공(1-4)과 다이아프램(1-5)를 설치하고, 에어실린더(1)와 점착슈(6) 사이에는 로드(2)와 링크(3)를 설치하여 차륜(5)에 점착슈(6)가 평행으로 구동되게 하였으며, 상기 점착슈(6)의 설치위치는 마찰에 의해 생성된 소결입자가 레일상에 떨어져 미산되는 것을 최대로 방지하면서, 차륜 자체의 원주속도에 의하여 차륜과 레일 사이로 원활하게 공급시킬 수 있는 레일상 약 15cm 위치의 차륜전방에 설치하는 것이 가장 바람직하다.The device of the present invention is the configuration of the air cylinder (1) on the left side of the air pipe (1-2), the air pressure portion (1-3) in the middle, the connection hole (1-4) and the diaphragm (1-5) on the right ) And a rod (2) and a link (3) are installed between the air cylinder (1) and the adhesive shoe (6) to drive the adhesive shoe (6) in parallel to the wheel (5). The installation position of (6) is about 15 cm on the rail that can be smoothly supplied between the wheel and the rail by the circumferential speed of the wheel itself while maximally preventing the sintered particles generated by friction from falling off on the rail. It is most preferable to install in front of the wheel.
이와같이 된 본 고안의 작용효과를 설명하면 다음과 같다.When explaining the effect of the present invention made as follows.
본 고안은 주행중에 있는 열차가 제동을 행하게 되면 대차에 취부된 에어실린더(1)의 공기배관(1-2)으로 압축공기가 주입되면 압축공기의 힘에 의하야 다이아프램(1-5)이 작동하는데, 다이아프램(1-5)이 점착슈(6)를 취부하고 있는 상, 하로드(2)에 의하여 점착슈(6)의 표면부를 차륜(5)의 전방 표면부에 접촉시키게 된다.According to the present invention, when compressed air is braked, when compressed air is injected into the air pipe (1-2) of the air cylinder (1) mounted on the bogie, the diaphragm (1-5) is driven by the force of the compressed air. In operation, the diaphragm 1-5 is brought into contact with the front surface portion of the wheel 5 by the upper and lower rods 2 on which the adhesive shoes 6 are attached.
점착슈(6)가 회전하고 있는 차륜(5)의 표면부에 접속되면, 그 사이의 마찰력으로 점착슈(6)의 접착 미립자가 차륜의 원주속도에 의해 레일과 차륜 사이로 공급되어 차륜이 이를 밟고 지나가게 되는 것인바, 모래를 뿌린것과 같은 효과를 거두면서 차륜(5)과 레일간의 점착력을 높여줄뿐만 아니라, 차륜(5) 표면에 부착된 이물질을 제거하여 승차감을 양호하게 하며, 브레이크 장치의 작동을 해제 즉, 차륜의 제동을 해체하게 되면 슈지지판(4)이 원위치됨에 따라 점착슈(6)가 차륜(5)의 표면으로부터 분리 이격되는 것이고, 장기간 사용으로 점착슈(6)의 마모도가 심하면 이를 새것으로 교체해 주면 되는 것이다.When the adhesive shoe 6 is connected to the surface portion of the rotating wheel 5, the adhesive microparticles of the adhesive shoe 6 are supplied between the rail and the wheel by the circumferential speed of the wheel by the frictional force therebetween, and the wheel steps on it. As it passes by, the effect of spraying sand not only improves the adhesion between the wheels 5 and the rails, but also removes foreign substances adhering to the surfaces of the wheels 5 to improve ride comfort, When the brake is released, that is, when the brake is released, the adhesive shoe 6 is separated from the surface of the wheel 5 as the shoe support plate 4 is returned to its original position. If it is bad, you can replace it with a new one.
특히, 본 고안은 우천이나 강설등과 같은 어떠한 악천후 조건하에서도 상기 점착슈(6)의 미립자가 레일위에 떨어져 차륜(5)과 레일간의 점착력을 크게하여 차륜(5)의 슬립과 스키드를 방지해서 차륜 슬립과 스키드에서 오는 차륜의 편마모 및 레일의 손상을 예방하므로써 차륜과 레일의 수명이 길게되어 차륜연삭이나 고체비용을 절약할 수 있으며, 보다 많고 확실한 제동거리를 확보할 수 있는 효과가 또한 있는 것이다.In particular, the present invention prevents slippage and skid of the wheels 5 by increasing the adhesion between the wheels 5 and the rails due to the fine particles of the adhesive shoe 6 falling on the rails under any bad weather conditions such as rain or snow. By preventing wheel slip and the wear of the wheels from skids and damage to the rails, the life of the wheels and rails can be prolonged to save wheel grinding and solid costs, and also to secure more and more stable braking distances. .
이상과 같이 본 고안은 평균감속도를 증대시켜 주므로서 차량의 평균속도향상 및 보다 짧고 확실한 제동거리를 확보할 수 있어 안전운행을 할 수 있으며, 점착슈 미립자에 의하여 차륜과 레일 사이에 점착력을 증가시키므로써 제때 정지 및 출발을 규정대로 이행할 수 있기 때문에 고속차량 또는 지하철 운영사업에도 원활하게 할 수 있는 실용적인 고안인 것이다.As described above, the present invention improves the average speed of the vehicle and secures a shorter and more stable braking distance by increasing the average deceleration, thereby enabling safe driving.Adhesive shoe particles increase the adhesion between the wheel and the rail. It is a practical design that can be carried out smoothly in high speed vehicles or subway operation projects because it can be carried out according to the regulations on timely stops and departures.
