이와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

제1도에서와 같이 공차완해시에는 송입관(1)으로 압축공기를 압송시키면 공기중 일부는 공기정화기(81)와 역지변(82)을 거쳐 공기통(C)로 유입되어 작용부(20)의 공기유입로(22)을 거쳐 작용부실(26)의 내부로 유입되려 하지만 하강된 개폐변(K)에 의해 입구가 폐쇄되어 진입되지 못하고 입구에서 대기상태로 있고 일부는 공기유입로(22')을 거쳐 비상변(90)의 상부실(0)에 유입됨과 동시에 연결관(83')(83'')을 통해 공급변(30)과 응하증변(50)에 공급된다. 하지만 공급변(30)과 응하중변(50)에는 각각의 피스턴(31)(52)이 상승 및 하강되어 공기유입구를 폐쇄시키고 있기 때문에 입구에서 대기 상태로 있는다.As shown in FIG. 1, when the tolerance is relaxed, pressurized air is pushed into the inlet pipe 1 so that a part of the air flows into the air chamber C through the air purifier 81 and the reverse valve 82, and the action part 20 It is going to flow into the inside of the working part chamber 26 through the air inlet path 22 of) but the entrance is closed by the lowered opening / closing side (K), it is not entered and is in the standby state at the inlet part, and the air inlet path 22 ') Is introduced into the upper chamber (0) of the emergency valve (90) and at the same time is supplied to the supply valve (30) and the dropping test 50 through the connecting pipe (83', 83 ''). However, each of the pistons 31 and 52 is raised and lowered on the supply side 30 and the load-bearing side 50 to close the air inlet, and thus the air is at the inlet.

또한 압송공기는 연결관(83)에 연결된 분배변(10)의 공기유입구(13) 및 상부실(14)에 공급되고 공급된 공기는 활변유입구(15)를 거쳐 상측유입구(17')과 일치된 통로를 통해 연결관(18)을 지나 압력공기실(2)에 압송 충전된다. 이때 피스턴(11)의 하부 유입구(17")는 피스턴(11)이 하강 상태이어서 실린더(12)의 작용관(16)과 엇갈려 있게 되어 작용부(20)쪽으로의 공기 공급이 차단된다.In addition, the pressurized air is supplied to the air inlet 13 and the upper chamber 14 of the distribution valve 10 connected to the connecting pipe 83, and the supplied air matches the upper inlet 17 'via the bow inlet 15. The pressure air chamber 2 is pressurized and filled through the connecting pipe 18 through the passage. At this time, the lower inlet 17 ″ of the piston 11 is in a descending state so that the piston 11 is crossed with the working tube 16 of the cylinder 12 to block the air supply to the working part 20.

따라서 작용부(20)에는 공기압력이 형성될 수 없어 복식제동통(60)을 구동시키지 못하며 제동이 완해된 상태로 있게 된다.Therefore, since the air pressure cannot be formed in the acting portion 20, the double braking cylinder 60 cannot be driven and the braking is relaxed.

이와 같은 공차의 완해시에서 공차를 제동시키기 위해서 송입관(1)의 공기를 배출시키게 되며 연결관(83)와 연결된 공급변(30)에서 대기했던 공기와 분배변(10)의 상부실(14)에 충전되었던 공기가 갑자기 배출되므로 인해, 압력공기실(2)의 공기가 충진되는 피스턴(11)하부와 기압이 배출된 상부실(14)은 높은 공기압력의 차이가 생기게 되어 피스턴(11)은 기압이 낮은 상부실(14)쪽으로 상승된다.When the tolerance is relaxed, the air of the inlet pipe 1 is discharged in order to brake the tolerance, and the upper chamber 14 of the air and the distribution valve 10 waited at the supply valve 30 connected to the connecting pipe 83. The air filled in the air is suddenly discharged, so that the lower portion of the piston 11 in which the air in the pressure air chamber 2 is filled and the upper chamber 14 in which the air pressure is discharged have a difference in high air pressure. Is raised toward the upper chamber 14 where the air pressure is low.

그와 동시에 피스턴(11)의 상부유입구(17')는 일치되었던 활변유입구(15)에서 벗어나 위쪽에 위치되고 반면에 작용관(16)에서 벗어나 있던 피스턴(11)의 하부유입구(17")가 일치되어 압력공기실(2)과 작용관(16)을 연통시켜 압력공기실(2)의 공기를 작용관(16)과 작용부(20)의 작용공기실(27)을 거쳐 막판 하부실(28)로 유입시켜 그 압력으로 피스턴(21)을 상승시킨다. 따라서 피스턴(21)의 상승됨에 따라 상부의 공기유입로(22)의 개폐변(K)이 상승되어 작용되어 작용부실(26)의 입구를 개방시키게 되어 공기통(C)의 압력공기가 작용부실(26)을 거쳐 공기송출로(25)와 연결관(84)을 거쳐 복식제동통(60)중 앞쪽의 공차제동 피스톤(62)을 구동시켜 제동을 시키게 되는 것이다.At the same time, the upper inlet 17 ′ of the piston 11 is positioned upwards away from the matched bow inlet 15, while the lower inlet 17 ″ of the piston 11 that is out of the actuation tube 16 is positioned. In accordance with this, the pressure air chamber 2 and the working tube 16 communicate with each other, so that the air in the pressure air chamber 2 passes through the working air chamber 27 of the working tube 16 and the acting portion 20, and thus, 28 to raise the piston 21 at the pressure, so as the piston 21 is raised, the opening / closing side K of the upper air inflow passage 22 is raised and acted to The inlet is opened so that the pressure air of the air cylinder C passes through the actuating chamber 26 and passes through the air delivery path 25 and the connecting pipe 84 to the front tolerance braking piston 62 of the double braking cylinder 60. Drive it to brake.

이와 같은 상태에서는 영차제동 피스턴(61)은 구동되지 않는 것으로 그 이유는 공기 송출로(25)를 통과한 공기가 중계변(40)에서 연결관(85)과 연통되지 못하고 스프링(42)에 의한 상승에 의해 막혀 있기 때문이다. 다음은 영차완해시의 작동상태로써 영차시에 하중을 받게된 응하중변(50)의 받침봉(51)이 차량의 사이드 프레임에 설치된 조정불트(86)에 접촉되면서 상승하게 되고 받침봉(51)이 상승함에 따라 피스톤(52)이 상승되어 입구를 개방시켜 주므로서 피스턴(52)의 하강으로 인해 대기해 있던 송입관(1)의 공기가 신속히 유입되어 연통된 공기배출관(87)을 통해 중계변(40)과 공급변(30)으로 압송되어 피스턴(41)(31)을 하강시킨다.In this state, the zero differential braking piston 61 is not driven because the air passing through the air delivery path 25 is not in communication with the connecting pipe 85 at the relay valve 40 and is caused by the spring 42. Because it is blocked by the rise. Next, the support rod 51 of the load bearing side 50 received the load at the time of zero vehicle as the operation state at zero vehicle loosening is raised as it comes in contact with the adjustment bulge 86 installed on the side frame of the vehicle and the support rod ( As the piston 51 rises, the piston 52 is lifted to open the inlet, and the air of the inlet pipe 1 that is waiting due to the descending of the piston 52 is rapidly introduced and communicated through the air discharge pipe 87. It is pumped to the relay side 40 and the supply side 30 to lower the piston (41) (31).

따라서 중계변(40)는 연결관(85)과 작용부(20)의 공기송출로(25)와 상호 연통되는 상태로 되며 공급변(30)에서는 공기송출로(32)와 하부공기유입관(33)을 연통시켜 주므로서 피스턴(31)의 하강으로 인해 대기해있던 송입관(1)의 공기는 하부공기 유입관(33)을 거쳐 공기송출로(32)을 통하여 공기통(D)(C)에 균등이 충전되는 것이다(제5도 참조).Therefore, the relay side 40 is in communication with the air delivery path 25 of the connecting pipe 85 and the working part 20, and the air supply path 32 and the lower air inlet pipe ( 33) communicates with the air in the inlet pipe (1), which is waiting due to the descending of the piston (31) through the air inlet (32) through the lower air inlet pipe (33) (D) (C) Is filled equally (see Figure 5).

이와 같은 상태에서 영차를 제동하기 위하여 송입관(1)의 압송공기를 배출시키면 응하중변(50)의 연결관(83)설치된 역지변(88)이내에 있는 연결관(83)에 연통되는 공기가 배출되는 것으로 공급변(30)에 유입되려는 공기가 분배변(10)의 상부실(14)에 충전되었던 공기가 배출되는 것으로 따라서 압력공기실(2)의 공기는공차시의 제동과 마찬가지로 동작되며 피스턴(11)을 상승시켜 공기통(C)의 공기를 공기송출로(25)로 통해 송출시킨다.In such a state, when the compressed air of the inlet pipe 1 is discharged to brake the zero-car, air communicating with the connection pipe 83 within the reverse side 88 installed in the connection pipe 83 of the load-bearing side 50 is provided. As the air to be introduced into the supply side 30 to be discharged is filled in the upper chamber 14 of the distribution side 10, the air in the pressure air chamber 2 is operated in the same manner as the braking at the tolerance. By raising the piston 11, the air in the air cylinder C is sent out through the air delivery path 25.

송출된 공기는 공차제동 피스턴(62)을 직접 구동시킴과 동시에 이미 영차 완해시에 피스턴(41)의 하강으로 인해 연결간(85)의 출구를 개방시켰던 중계변(40)으로 공급되어 연결관(85)을 통해 영차제동 피스톤(61)을 동작시키게 된다.The air sent out is directly driven to the tolerance braking piston 62 and is supplied to the relay valve 40 which has already opened the outlet of the connecting rod 85 due to the lowering of the piston 41 at the time of zero vehicle relaxation. The zero differential brake piston 61 is operated through 85.

따라서 영차제동시에는 공기통(C)의 공기압을 영공차제동 피스턴(61)(62) 양자에 공급하여 구동시키는 것으로 압송되는 공기가 복식제동통(60)의 영차제동 피스턴(61)을 밀어서 공차시 동작했던 공차제동 피스턴(62)을 밀게 되고 이와 동시에 공차제동 피스턴(62)도 공차제동시와 동일하게 동작되며 밀어주게 되는 것으로 제동력이 약 2배로 높아져 영차제동작용을 더욱 완벽하계 수행할 수 있는 것이다.Therefore, in zero braking, the air being compressed by supplying and driving the air pressure of the air cylinder C to both of the air tolerance braking pistons 61 and 62 drives the zero difference braking piston 61 of the double braking cylinder 60 to the tolerance. The tolerance braking piston that was operated is pushed, and at the same time, the tolerance braking piston 62 is operated in the same way as the tolerance braking and is pushed, and the braking force is about doubled, so that the zero-braking action can be performed more perfectly. .

또한, 영공차 제동시에 생기는 공기통(C)의 공기압 저하는 이와 연통된 공기통(D)에서 즉시 보충되는 것으로 항시 균일하고 강력한 압력을 가해 제동력을 높여 주게 되는 것이며 또한 영차 상태가 해제되어 받침봉(51)이 조정볼트(86)에서 이탈되면 응하중변(50)에서 중계변(40) 그리고 공급변(30)의 연결관(87)에 있던 공기를 응하중변(50) 상부배출구로 제거하여 공차시의 동작이 이루어질 수 있도록 하며 이상의 설명은 상용제동의 설명이며 비상제동시는 비상변(90)이 동작되어 비상제동이 수행되는데 이는 비상변(90) 하부실(G)에서 졸림구(H)를 통하여 용적실(i)에 공급되었던 제동관 공기가 비상제동시 갑자기 하부실(G)의 공기가 낮아지면 용적실(i)의 압력공기에 의해 피스턴(J)을 상승시키며 공급변(Q)이 열리므로 상부실(O)에 있던 압력공기가 중간실(P)을 통하여 역지변(88'')을 지나 피스턴(21) 막판 하부실(28)에 높은 압력이 공급되므로 비상제동이 체결되며 설정치 이상의 압력이 작용되었을때는 안전변(T)이 동작되어 필요이상의 제동을 체결되지 않도록 한다(제4, 5도 참조).In addition, the air pressure drop of the air cylinder (C) generated during braking of the airspace is immediately compensated for in the air cylinder (D) in communication with it, thereby increasing the braking force by applying a uniform and powerful pressure all the time, and also the support rod (51). ) Is removed from the adjustment bolt (86) to remove the air in the connection side (87) of the relay side (40) and the supply side (30) from the load side (50) to the upper outlet of the load side (50) The operation of the city can be made and the above description is the description of the commercial braking and the emergency braking is performed by the emergency valve (90) during emergency braking which is performed in the lower chamber (G) of the emergency valve (90). When the air in the lower chamber G suddenly lowers during emergency braking of the braking tube air supplied to the volume chamber i through the air, the piston is raised by the pressure air of the volume chamber i, and the supply valve Q is applied. Is opened so that the pressure air in the upper chamber O passes through the intermediate chamber P. As the high pressure is supplied to the lower chamber 28 of the last plate of the piston 21 after passing through the area side 88 '', the emergency braking is engaged. When the pressure exceeds the set value, the safety valve T is activated to engage the braking more than necessary. (See also paragraphs 4 and 5).

이상과 같은 본 발명을 영차와 공차의 제동을 위해 별도의 제동변을 구비할 필요없이 1개의 분배변과 작용부로 제어가 가능도록 하므로서 구성이 비교적 간단하여 설치 및 수리가 용이하고 작동이 정확한 잇점이 있는 것이다.As described above, the present invention can be controlled by one distribution valve and a working part without the need of a separate braking valve for braking the zero difference and the tolerance. It is.
