이때, 제동관(BP) 압력의 증감에 따라 막판 피스톤(12)이 상·하로 움직여 적당한 제동작용을 제어하며 비상제동시 급동공기통(BR)의 압력공기가 공기관(107, 107')을 지나 KA-3 제어변(10) 비상부(10″) 상부실(g)에 공급대기하고, 압력공기통(PR)의 압력공기는 막판 피스톤(12') 하부에 공급되어 비상 제동시 급동공기통(BR)의 압력공기가 공기관(108)을 통하여 KA-4 중계변(20)의 막판 피스톤(28) 중간실(21)에 공급되도록 하여 비상제동이 체결되도록 하고, 배기변(30)은 제동후, 수동 완해시 완해작용을 하기 위해 배기변(30)의 하부실(P')에 공급되었던 공기관(105) 압력은 공급 공기통(SR)의 배수콕크를 개변시켜 대기로 배출시키면 피스톤(W)이 상부 스프링의 탄력에 의해 하강하면 변(P)이 개변되어 작용공기통(KR)의 압력공기가 배기구(32)를 통해 대기로 빠져 완해작용이 되도록 하고 영공식 응하중변(40, 40')은 하중 적재에 따라 공기관(102)의 압력공기를 공급시켜 공기관(103)으로 유입시킴으로서 KA-4 중계변(20) 하실(25)로 공급 막판(22)을 상승시켜 막판 피스톤(28)의 제동작용때 막판 피스톤(22) 아래로 전달되는 압력을 지점변화를 통해 해정시킴으로서 제동통과 막판피스톤(28) 상부실(27)로 유입되는 압력공기를 조절하여 하중에 따른 제동력을 얻도록 하며, 등속작용변(50)과 제동통(60)은 연결관(105), KA-4 중계변(20)과 연결관(106)을 경유 공급공기통(SR)의 압력공기가 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 12 moves up and down to control the proper braking action, and during the emergency braking, the pressure air of the braking air cylinder BR passes through the air pipes 107 and 107 'KA. -3 Waiting for supply to the control chamber (10), upper part (g) of the emergency part (10 ″), and the pressure air of the pressure air cylinder (PR) is supplied to the lower part of the last piston (12 ').

이와 같은 본 발명의 작용상태를 설명하면 다음과 같다.Referring to the operation state of the present invention as follows.

도 1에 도시된 바와 같이, 차량에 제동장치를 설치한 상태에서, 제동관(BP)에 압력공기를 압송시키면 제동 공기관(100)을 통하여 KA-3 제어변(10) 비상부(10″) 중간실(K)과 제어부(10') 막판피스톤(12) 하부실(11)로 공급되면서 비상부 중간실(K)에서 볼 역지변(14)을 지나 하부실(O)을 경유 공기관(109)을 통하여 압력공기통(PR)과 제어부(10')의 하부실(b)과 이에 연통된 비상부(10″) 막판 피스톤(12') 하부실(O)에 공급되고, 역지변(125)을 지나 급동공기통(BR)에 공급시키고 역지변(126)을 지나 영공식 응하중변(40, 40') 상부실에 공급되고 역지변(127)을 지나 공급공기통(SR)에 충만 시키면서 KA-4 중계변(20)의 상부실(T)에 공급된다.As shown in FIG. 1, when pressure air is pushed into the braking pipe BP while the braking device is installed in the vehicle, the emergency unit 10 ″ of the KA-3 control valve 10 is provided through the braking air pipe 100. The air pipe 109 is supplied to the lower chamber 11 of the middle chamber K and the control unit 10 ', and the lower chamber 11 is passed through the ball reverse side 14 from the emergency middle chamber K. Is supplied to the lower chamber (b) of the pressure air cylinder (PR) and the control unit (10 ') and the emergency section (10 ″) last-minute piston (12') lower chamber (O) in communication therewith, After passing through the stationary valve (126) and supplying to the air chamber (BR) and passing through the reverse zone (126) to the upper chamber of the air-responsive load (40, 40 '), and filled through the reverse zone (127) to the supply air (SR) 4 is supplied to the upper chamber T of the relay side 20.

이상태에서, 제동을 체결하면 도 2에 도시된 바와 같이, 제동관(BP)의 공기를 대기로 적당량을 배출시켜 제동 공기관(100)의 전체 공기압을 감압시키면, 이때, KA-3 제어변(10) 제어부(10')의 막판피스톤(12) 하부실(11)의 압력공기가 제동 공기관(100)의 압력과 같이 감압되므로 상부실(15)의 공기 압력에 의해 막판 피스톤(12)이 아래로 작용되는데, 이는 압력공기통(PR)에 압력이 공급될 때 역지변(14)과 졸림구(13)를 통해 서서히 공급되었던 압력공기가 제동 공기관(100)의 압력이 감압될 때 압력공기통(PR)의 압력은 빠질 수 없으므로 막판 피스톤(12)의 상부실(15) 공기 압력에 의해 막판 피스톤(12)이 아래로 작용하게 되는 것이다.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 to reduce the total air pressure of the braking air tube 100, at this time, the KA-3 control valve 10 ) Since the pressure air of the lower chamber 11 of the membrane plate piston 12 of the controller 10 'is reduced with the pressure of the braking air tube 100, the membrane piston 12 is moved downward by the air pressure of the upper chamber 15. The pressure air cylinder PR is applied when the pressure of the braking air pipe 100 is gradually reduced when the pressure air, which has been gradually supplied through the reverse valve 14 and the sleeper port 13, is supplied with pressure to the pressure air cylinder PR. Since the pressure cannot be released, the membrane piston 12 acts downward by the air pressure of the upper chamber 15 of the membrane piston 12.

한편, KA-3 제어변(10) 제어부(10')의 하부에 설치된 공급변(6)이 배기구(16)쪽으로 이르는 프란자(7)내부 구멍을 막은 상태에서 열리게 되므로 압력공기통(PR)의 압력공기가 공기관(108)을 통하여 KA-4 중계변(20) 막판 피스톤(28) 중간실(21)과 작용공기통(KR)에 공급되는데 KA-3 제어변(10) 제어부(10')의 하부 공급변(6)이 랩위치로 될 때까지 등속작용변(50) 막판(13') 하실(48)을 경유 연결관(108')을 지나 막판 피스톤(28) 중간실(21)에 공급된다.On the other hand, since the supply side 6 installed in the lower portion of the control section 10 'of the KA-3 control valve 10 is opened in a state in which the hole inside the franza 7 reaching the exhaust port 16 is closed, the pressure air cylinder PR Pressure air is supplied to the intermediate chamber 21 of the KA-4 relay valve 20, the last piston 21, and the working air cylinder KR through the air pipe 108. The control unit 10 'of the KA-3 control valve 10 is Supply the constant velocity action valve 50, the membrane plate 13 'and the basement 48 through the connecting pipe 108' via the connecting pipe 108 'to the intermediate chamber 21 until the lower feed valve 6 is in the lap position. do.

따라서, KA-4 중계변(20) 막판 피스톤(28)이 위로 상승되고 지점 전달부가 상승되어 공급변(26)을 개방하므로서, 상부실(T)에 공급되어 있던 공급공기통(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 KA-4 relay valve 20 valve piston 28 is lifted up and the point transfer part is opened to open the supply valve 26. Is supplied to the braking cylinder 60 through the air pipe 106 to obtain a braking force.

이때, KA-4 중계변(20)의 막판 피스톤(28) 상부실(27)에 공급된 압력공기는 막판 피스톤(28)의 하부실(21)에 공급된 압력공기와 상세되어 막판 피스톤(28)이 하강되고 공급변(26)이 차단되는 랩 위치를 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 KA-4 relay side 20 is described in detail with the pressure air supplied to the lower 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.

비상제동시에는 도 3에 도시된 바와 같이, 제동 공기관(100)의 공기가 급강하하면, KA-3 제어변(10) 비상부(10')의 막판 피스톤(12')의 상부실(K)에 압력공기가 급하강되므로 하부실(O)에 공급되었던 압력공기통(PR)의 압력공기에 의해 막판 피스톤(12')이 급상승되어 비상 공급변(6')이 개변되어 급동공기통(BR)의 압력 공기가 KA-4 중계변(20)의 막판 피스톤(28) 중간실(21) 및 작용공기통(KR)에 공급되므로 도 2의 상용제동시 제동 체결속도가 상용제동시 보다 빠르고 압력공기통(PR) 체적비 증가분 만큼 높은 제동력을 얻을 수 있는 것이다.In emergency braking, as shown in FIG. 3, when the air in the braking air tube 100 drops sharply, the upper chamber K of the membrane piston 12 'of the emergency section 10' of the KA-3 control valve 10 As the pressure air drops rapidly, the last piston 12 'is suddenly increased by the pressure air of the pressure air cylinder PR supplied to the lower chamber O, and the emergency supply valve 6' is modified to change the emergency air cylinder BR. Since the pressure air is supplied to the middle chamber 21 of the piston piston 28 of the KA-4 relay side 20 and the working air cylinder KR, the braking fastening speed in the commercial braking of FIG. 2 is faster than that of the commercial braking and the pressure air cylinder PR ) As much as the volume ratio increase, the braking force can be obtained.

본 발명에 따른 제동장치의 배기변의 작동상태를 설명하면 도 1에 도시된 바와 같이, 수동 완해시 공급공기통(SR) 공기를 배출하고 작용 공기를 배출치 않으면 공급공기통(SR)에 재차 공기 충만시 제동이 체결되는 현상이 발생되므로 이를 방지하기 위하여 배기변(30)에서 피스톤(W) 하부실(P')의 압력공기를 공급공기통(SR)에서 배수콕크의 개변으로 압력이 빠질 때, 스프링의 탄발력에 의해 피스톤(W)이 하방으로 내려지도록 하여 배기변(P)이 개변되고 이때, 작용공기통(KR)에 공급된 압력공기를 배기변(30) 배기구(32)를 통하여 대기로 빠지게 되면, KA-4 중계변(20) 막판 피스톤(28) 중간실(21)에 압력공기가 동시에 대기로 빠지게 되어 재차 제동 체결이 되지 않으며 공급공기통(SR)에 재차 공기 압력의 공급시는 배기변(30) 피스톤(W) 하부실(P')에도 동시에 공급되므로 배기변(P)이 닫혀 제동작용시 작용공기통(KR) 공기가 대기로 빠질 수 없게 되어 정상적인 제동 작용이 이루어지게 된다.Referring to the operating state of the exhaust valve of the braking device according to the present invention, as shown in Figure 1, when the manual loosen the supply air (SR) to discharge the air, if the operating air does not discharge the supply air (SR) again when the air is filled again When the braking is engaged, the pressure of the lower chamber P 'of the piston W in the exhaust valve 30 is reduced from the supply air cylinder SR to the opening of the drain cock. When the piston W is lowered by the elastic force, the exhaust valve P is modified and at this time, the pressure air supplied to the working air cylinder KR falls out into the atmosphere through the exhaust port 32 of the exhaust valve 30. , KA-4 relay valve 20, pressure air in the middle chamber 21 of the last piston (28) at the same time to the atmosphere at the same time as the brake is not tightened again, and when the air pressure is supplied again to the supply air (SR) exhaust valve ( 30) The piston (W) is also supplied to the lower chamber (P ') at the same time. Is not gibyeon times (P) is closed, can act during braking air passage (KR) the air fall to the atmosphere becomes a normal braking operation done.
