Description

화차용 제동장치{Brake System for the use of Freight Train}Brake System for the use of Freight Train

본 발명은 화차용 제동장치에 관한 것으로서, 보다 상세하게는 철도차량 화차의 제동을 위해 사용되는 제동장치의 구조를 간편화하고 화물적재에 따라 제동력을 증·감시켜 성능 및 제동력을 향상시킨 제동장치에 관한 것이다.The present invention relates to a braking device for a wagon, and more particularly, to a braking device that simplifies the structure of a braking device used for braking a railroad car and improves performance and braking power by increasing and decreasing braking force according to cargo loading. It is about.

일반적으로, 화차용 제동장치는 금속으로 만들어진 피스톤과 활변 및 활변좌로된 슬라이드 식으로 필요한 구멍을 적합시켜 공기를 유통 차단하여 사용하고 있다.In general, a brake for a wagon is fitted with a hole made of a piston made of a metal, and a slide type made of a bow and a bow seat to block air flow.

이런 종래의 화차용 제동장치는 구조가 복잡하고 정밀도가 떨어져 이로 인해 누설과 오동작이 발생하게 되며, 또한 보수 유지에 따른 숙련된 인력과 고도의 시설이 필요하게 된다.Such a conventional braking device for a wagon is complicated in structure and inferior in accuracy, thereby causing leakage and malfunction, and requiring skilled personnel and high-level facilities for maintenance.

또한, 하물적재에 따른 제동력을 영차시(화물 적재 상태)와 공차시(화물 무적재 상태)의 2단식으로만 구분 사용하고 있어서, 총 30량이 연결된 차량의 제동시 화물이 많게 적재된 차량은 계속 달리려 하고 화물이 적은 차량은 서려고 하는 차량들간의 충돌현상이 일어나게 되어 열차 제동으로 인한 차량간의 충돌은 열차간 연결의 단락이나 탈선을 우려가 있는 문제점이 있었다.In addition, the braking force according to the cargo loading is divided into two stages of zero-carrying (cargo loading) and tolerance (cargo-free loading). As a result, collisions between vehicles that are going to run and vehicles that are low in cargo are about to stand. Therefore, collisions between vehicles due to train braking have a problem of short-circuit connection or derailment.

뿐만 아니라, 영차나 공차에 상관없이 열차의 속도 최고 90㎞/h로 주행중 600m 이내에서 정차하여야 되는 규정에 의해 기관사는 차량의 무게에 따라 제동거리 600m 이내에서 정차되게 끔 조절하여야 하기 때문에 열차가 공차시(화물 무적재 상태)에는 최고속도로 달리고 일정거리에서 제동시킬 수 있지만, 총 30량의 열차중에서 실제로 실린 화물의 무게는 차량마다 서로 차이가 많이 나기 때문에 기관사가 제동거리를 가늠하여 600m이내에서 정차하기가 어려웠고, 600m이내에서 정차하기 위해서는 차량의 운행속도를 보다 올려 고속으로 열차를 달릴 수가 없어 열차의 운행시간이 많이 소요되는 문제점이 있었다.In addition, due to the regulation that the vehicle should stop within 600m while driving at speeds of 90km / h, regardless of zero or tolerance, the engineer must adjust the vehicle to stop within 600m of the braking distance according to the weight of the vehicle. City can run at maximum speed and brake at a certain distance, but the weight of cargo actually loaded on a total of 30 trains varies greatly from vehicle to vehicle, so the engineer stops within 600m by measuring the braking distance. It was difficult to stop, and to stop within 600m, there was a problem that the running time of the train takes a lot because the train can not run at high speed by increasing the driving speed of the vehicle.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 구조를 간편화하고 보수유지가 용이하고 정밀도를 향상시켜 누설에 의한 오동작을 방지할 수 있으며 또한 하물 적재에 따라 비례한 제동력 및 안정성이 향상된 새로운 형태의 화차용 제동장치를 제공함에 그 목적이 있다.The present invention is to solve the conventional problems as described above, to simplify the structure, easy maintenance and improve the accuracy to prevent the malfunction due to leakage and also improve the proportional braking force and stability according to the load loading new It is an object of the present invention to provide a braking device for a wagon.

제동장치에 기관차로부터 공급된 제동관(BP)의 압력공기가 공기 정화기(70)와 공기관(101) 및 역지변(127)을 경유하여 공급공기통(SR)에 충만시키고, 공기관(105)을 통해 IBS-5 중계변(20) 상부실(T)에 공급하고 IBS-5 중계변(20)이 동작하여 공기관(106)을 통하여 제동통(60)으로 유입되도록 한다.The pressure air of the braking tube BP supplied from the locomotive to the braking device is filled with the supply air SR via the air purifier 70, the air tube 101, and the reverse valve 127, and through the air tube 105. The IBS-5 relay side 20 is supplied to the upper chamber T, and the IBS-5 relay side 20 is operated to be introduced into the braking tube 60 through the air pipe 106.

등속작용변(50)은 연결관(108)으로 유입된 압력공기실(PR)의 압력 공기가 IBS-5 중계변(20) 막판 피스톤 중간실(21)로 유입될 때 막판 피스톤(53)의 힘으로 공급변(54)이 하강 유입구(52)를 줄여 앞·뒤 차량의 제동작용 속도를 맞춘다.The constant velocity action valve 50 is formed when the pressure air in the pressure air chamber PR introduced into the connecting pipe 108 flows into the membrane piston middle chamber 21 of the IBS-5 relay valve 20. The supply side 54 reduces the falling inlet 52 by force to adjust the braking action speed of the front and rear vehicles.

IBS-5 제어변(10)은 제동관(BP) 압력공기가 공기관(101)을 통하여 IBS-5 제어변(10) 제어부(10a) 막판 피스톤(12) 상부실(11)과 막판피스톤(12)에 설치된 볼 역지변(14)을 통하여 압력공기실(PR)과 제어공급부실(b)에도 공급되고 비상부(10b) 피스톤(12b) 상부실(11b)과 피스톤(12b)에 설치된 오리피스(14b)를 통하여 용적공기실(a)에도 유입된다.The IBS-5 control valve 10 has a braking pipe (BP) pressure air through the air pipe 101, and the IBS-5 control valve 10, the control unit 10a, the valve piston 12, the upper chamber 11 and the valve piston 12 Orifice (12), which is supplied to the pressure air chamber (PR) and the control supply chamber (b) through the ball reverse valve 14 installed in the It also flows into the volume air chamber a through 14b).

이때, 제동관(BP) 압력의 증감에 따라 막판 피스톤(12)이 상, 하로 움직여 적당한 제동작용을 제어하며 비상제동시 급동공기실(BR)의 압력공기가 연결관(107)을 지나 IBS-5 제어변(10) 비상부(10b) 비상공급부(G)에서 연결(108)을 통하여 IBS-5 중계변(20)의 막판 피스톤(28) 중간실(21)에 신속히 공급되도록 하여, 비상제동이 체결되도록 하고, 응하중변(40, 40a)은 화물 적재에 따라 공기관(102)의 압력 공기를 변동시켜 공기관(103)으로 유입시킴으로서 바란스밸브(90)와 공기관(104)을 통해 IBS-5 중계변(20) 하실(25)로 공급, 막판(22)을 상승시켜 막판 피스톤(28)의 제동작용때 막판 피스톤(22) 아래로 전달되는 압력을 지점 변화를 통해 해정시킴으로서 제동통(60)과 막판피스톤(28) 상부실(27)로 유입되는 압력공기를 조절하여 화물적재량에 따른 제동력을 얻도록 하며, 제동통(60)은 공급 공기통(SR)의 압력 공기가 공기관(105)과 IBS-5 중계변(20) 및 공기관(106)을 경유 피스톤실 (61)에 유입하여 제동작용을 일으키게 되는 것이다.At this time, according to the increase and decrease of the pressure of the braking pipe (BP), the last piston piston 12 moves up and down to control proper braking action, and the pressure air of the braking air chamber BR passes through the connecting pipe 107 during the emergency braking. 5 Control valve (10) Emergency part (10b) The emergency supply part (G) provides a quick supply to the intermediate chamber (21) of the valve piston (28) of the IBS-5 relay valve (20) via a connection (108). The load sides 40 and 40a change the pressure air of the air pipe 102 according to the load of the air, thereby introducing the air into the air pipe 103 by the IBS-5 through the balance valve 90 and the air pipe 104. The brake barrel 60 is provided by supplying the relay valve 20 to the base 25 and raising the membrane 22 to release the pressure transmitted below the membrane piston 22 during the braking action of the membrane piston 28 through a point change. And to control the pressure air flowing into the upper chamber 27 of the membrane plate piston 28, to obtain a braking force according to the load capacity, the braking barrel 60 Pressure air of the supply reservoir (SR) flows into the piston chamber (61) via the air pipe (105), the IBS-5 relay valve (20) and the air pipe (106) to cause a braking action.

이와 같은 본 발명의 작용 상태를 설명하면 다음과 같다Referring to the operation state of the present invention as follows.

도1에 도시된 바와 같이, 차량에 제동장치를 설치한 상태에서, 제동관(BP)에압력공기를 압송시키면 공기정화기(70)와 제동공기관(101)을 통하여 IBS-5 제어변(10) 비상부(10b) 막판피스톤(12b)의 상부실(11b)과 제어부(10a) 막판피스톤(12) 상부실(11)로 공급되면서 막판피스톤(12b)에 설치된 오리피스(14b)를 지나 용적공기실(a)에 충만된다.As shown in FIG. 1, when the pressure air is pushed into the braking tube BP while the braking device is installed in the vehicle, the IBS-5 control valve 10 is controlled through the air purifier 70 and the braking air engine 101. It is supplied to the upper chamber 11b of the emergency exit part 10b and the last chamber 11b of the control plate 10b, and passes through the orifice 14b installed in the last valve piston 12b while being supplied to the upper chamber 11 of the last valve piston 12b. filled with (a).

제어부(10a) 막판 피스톤(12)에 설치된 볼 역지변(14)을 지나 압력공기실(PR)에 충만되면서 연결관(도시않음)을 통하여 제어부(10a)의 제어공급실부실(b)에 공급되고, 역지변(125)을 지나 급동공기실(BR)에 공급시키면서 연결관(107)을 통하여 비상공급부실(G)에 공급되고, 역지변(126)을 지나 응하중변(40,40a) 상부실에 공급되고, 역지변(127)을 지나 공급공기통(SR)에 충만시키면서 IBS-5 중계변(20)의 상부실(T)에 공급된다.The control unit 10a is supplied to the control supply chamber unit b of the control unit 10a through a connecting pipe (not shown) while filling the pressure air chamber PR through the ball reverse valve 14 installed in the last piston 12. After passing through the reverse side 125 and supplying to the emergency air chamber BR, it is supplied to the emergency supply part chamber G through the connecting pipe 107, and passes through the reverse side 126 to the load-bearing side 40, 40a. It is supplied to the subsidiary chamber and is supplied to the upper chamber T of the IBS-5 relay side 20 while filling the supply air cylinder SR through the reverse side 127.

이 상태에서, 제동을 체결하면 도2에 도시된 바와 같이, 제동관(BP)의 공기를 대기로 적당량을 배출시켜 제동관(BP)과 제동공기관(100)(101)의 전체 공기압을 감압시키면, 이때, IBS-5 제어변(10) 제어부(10a)의 막판 피스톤(12) 상부실(11)의 압력공기가 제동공기관(101)의 압력과 같이 감압되므로 압력공기실(PR)의 공기 압력에 의해 막판 피스톤(12)이 위로 작용된다.In this state, when the braking is engaged, as shown in FIG. 2, when the air in the braking tube BP is discharged to the atmosphere, the total air pressure of the braking tube BP and the braking air engine 100 and 101 is reduced. At this time, since the pressure air of the upper chamber 11 of the last piston 12 of the control section 10a of the IBS-5 control valve 10 is reduced with the pressure of the braking air engine 101, the air pressure of the pressure air chamber PR is reduced. The membrane piston 12 is actuated upwards.

이는 압력공기실(PR)에 압력이 공급될 때 볼 역지변(14)과 졸림구(13)를 통해 서서히 공급되었던 압력 공기가 제동공기관(101)의 압력이 감압될 때 압력공기실(PR)의 압력은 빠질 수 없으므로 막판 피스톤(12)의 하부의 압력공기실(PR) 공기 압력에 의해 막판 피스톤(12)이 위로 작용하게 되어 막판피스톤(12)이 상승하면서 신속 제동실(30)의 연결관(110)이 개방되어 막판 피스톤(12) 상부실(11)의 압력공기가 빠르게 감압되어 더 빠른 제동작용을 하게 된다.This is because the pressure air, which has been gradually supplied through the ball reverse side 14 and the sleeper port 13 when the pressure is supplied to the pressure air chamber PR, is reduced in the pressure of the brake air engine 101, the pressure air chamber PR. Pressure cannot be released, so the piston valve 12 is actuated upward by the pressure air chamber PR air pressure at the bottom of the membrane piston 12 so that the membrane piston 12 rises and the rapid braking chamber 30 is connected. The pipe 110 is opened to quickly depressurize the pressure air of the upper chamber 11 of the last piston 12 to perform a faster braking action.

한편, IBS-5 제어변(10) 제어부(10a)의 상부에 설치된 공급변(6)이 배기구 (16)쪽으로 이르는 프란자(7) 내부 구멍(15)을 막은 상태에서 열리게 되므로 압력공기실(PR)의 압력공기가 연결관(108)(108b)을 통하여 IBS-5 중계변(20) 막판 피스톤(28) 중간실(21)과 작용공기실(KR)에 공급되는데 IBS-5 제어변(10) 제어부(10a)의 상부 공급변(6)이 랩위치로 될 때까지 등속작용변(50) 막판(53) 상부실(48)을 경유 연결관(108b)을 지나 막판 피스톤(28) 중간실(21)에 공급된다.On the other hand, since the supply side 6 provided on the upper part of the IBS-5 control side 10 control part 10a opens in the state which blocked the inside hole 15 of the francza 7 which leads to the exhaust port 16, the pressure air chamber ( The pressure air of the PR is supplied to the intermediate chamber 21 and the working air chamber KR of the IBS-5 relay valve 20, the last valve 20, through the connecting pipes 108 and 108b. 10) The middle of the last piston piston 28 through the connecting pipe 108b via the constant velocity action valve 50, the dead end 53, and the upper chamber 48 until the upper feed side 6 of the control unit 10a is in the lap position. It is supplied to the chamber 21.

따라서, IBS-5 중계변(20) 막판 피스톤(28)이 위로 상승되고 지점 전달부가 상승되어 공급변(26)을 개방하므로서, 상부실(T)에 공급되어 있던 공급 공기통(SR)의 압력공기가 공기관(106)을 통하여 제동통(60)에 공급되어 제동력을 얻게 되는 것이다.Accordingly, the pressure air of the supply air cylinder SR supplied to the upper chamber T is opened while the IBS-5 relay valve 20 last plate piston 28 is lifted up and the point delivery unit is raised to open the supply valve 26. Is supplied to the braking cylinder 60 through the air pipe 106 to obtain a braking force.

이때, IBS-5 중계변(20)의 막판 피스톤(28) 상부실(27)에 공급된 압력공기는 막판 피스톤(28)의 중간실(21)에 공급된 압력공기와 상쇄되어 막판 피스톤(28)이 하강되고 공급변(26)이 차단되는 랩위치를 취하게 되므로 제동통(60)에 공급되는 공기를 차단하게 된다.At this time, the pressure air supplied to the upper chamber 27 of the last piston piston 28 of the IBS-5 relay valve 20 is offset by the pressure air supplied to the middle chamber 21 of the last piston piston 28. ) Is lowered and takes the wrap position in which the supply side 26 is blocked, thereby blocking the air supplied to the braking cylinder 60.

비상 제동시는 도2에 도시된 바와 같이, 제동공기관(101)의 공기가 급강하하면, IBS-5 제어변(10) 비상부(10b)의 막판 피스톤(12b)의 상부실(11b)에 압력공기가 급하강되므로 용적공기실(a)에 공급되었던 압력공기에 의해 막판 피스톤(12b)이 급상승 비상 공급변(6b)이 개변되어 급동공기실(BR)의 압력 공기가 IBS-5 중계변(20)의 막판 피스톤(28) 중간실(21) 및 작용공기실(KR)에 공급되므로 도 2의상용제동시 제동 체결 속도 보다 빠르고 압력공기실(PR) 및 급동공기실(BR) 대비 작용공기실(KR)의 체적비 증가분만큼 높은 제동력을 얻을 수 있는 것이다.In the emergency braking, as shown in FIG. 2, when the air in the braking air engine 101 drops sharply, the pressure is applied to the upper chamber 11b of the membrane piston 12b of the emergency section 10b of the IBS-5 control valve 10. As the air is drastically lowered and the air pressure is supplied to the volume air chamber (a), the last piston 12b suddenly rises and the emergency supply valve 6b is opened to change the pressure air of the hydraulic air chamber BR to the IBS-5 relay valve ( 20 is supplied to the intermediate chamber 21 of the piston piston 28 and the working air chamber KR so that the working air chamber is faster than the braking fastening speed in the commercial braking of FIG. 2 compared to the pressure air chamber PR and the braking air chamber BR. As much as the volume ratio increase of (KR), the braking force can be obtained.

영차(화물 적재 상태) 제동시에는 도 2의 제동체결과 같으나, 응하중변(40, 40a)의 작용에 의해 화물 적재량에 비례하여 공기관(102)의 압력공기가 공기관(103,104)을 통해 IBS-5 중계변(20)의 막판 피스톤(22) 하부실(25)로 유입시켜 막판 피스톤(28)의 제동 작용 때 막판 피스톤(22) 아래로 전달되는 압력을 지점 변화를 통해 해정시킴으로써 제동통(60)과 막판피스톤(28) 상부실(27)로 유입되는 압력 공기를 조절되어 제동통(60)으로 유입되는 압력 공기가 공급되므로 화물 적재량에 따른 제동력을 얻을 수 있는 것이다.At the time of braking of the zero car (cargo loading state), it is the same as the brake body of FIG. 2, but the pressure air of the air pipe 102 is proportional to the cargo load by the action of the load load sides 40 and 40a through the air pipes 103 and 104. 5 The braking tube 60 is released by flowing into the lower chamber 25 of the valve piston 22 of the relay side 20 and releasing the pressure transmitted under the valve piston 22 through the point change during braking action of the valve piston 28. ) And the pressure air flowing into the upper chamber 27 of the membrane plate piston 28 is supplied, so that the pressure air flowing into the brake cylinder 60 is supplied, thereby providing a braking force according to the cargo load.

이렇게 본 발명은 차량의 제동동작과 화물 적재량에 따라 필요한 제동력을 얻을 수 있는 것이다.Thus, the present invention can obtain the required braking force according to the braking operation of the vehicle and the load of cargo.

이와 같은 본 발명에 따른 화차용 제동장치를 이용함으로서, 제동장치의 구조를 간편화할 수 있어 보수 유지가 용이하고 정밀도를 향상시켜 누설에 의한 오동작을 방지할 수 있으며, 또한 화물 적재량에 따라 비례로 제동력을 증가시킬 수 있어 제동력 및 안전성을 향상시킬 수 있을 뿐만 아니라, 제작비용을 크게 절감할 수 있는 효과가 있다.By using the braking device for a wagon according to the present invention, it is possible to simplify the structure of the braking device, so that maintenance and maintenance are easy, and accuracy can be prevented from malfunctioning due to leakage, and the braking force is proportional to the cargo load. It can increase the braking power and safety can be increased, as well as can significantly reduce the manufacturing cost.
