본 고안은 철도차량에 있어서 차체와 대차사이에 설치되어 완충역활을 하는 공기 스프링에 공급되는 압축공기의 양을 차체와 대차의 상대높이 변동에 따라 자동적으로 조절하는 압축공기 자동 조절밸브에 관한 것이다.The present invention relates to a compressed air automatic control valve for automatically adjusting the amount of compressed air supplied to an air spring, which is installed between the vehicle body and the bogie and acts as a buffer in a railway vehicle, in accordance with the relative height variation of the body and the bogie.

종래 철도차량에 있어서는 차체와 대차사이에 스프링과 오일댐퍼를 설치하여 완충작용을 하도록 하였으나 근래 차량이 고급화 됨에 따라 승객으로 하여금 보다 안락한 승차감을 느낄 수 있도록 하고 차체의 높이를 일정하게 유지시키기 위하여 공기 스프링과 공기스프링에 압축공기를 조절하여 공급하는 밸브를 설치하고있다.In the conventional railway vehicles, a spring and an oil damper were installed between the body and the bogie to provide a buffering effect. However, in recent years, as the vehicle becomes more advanced, air springs are provided to allow passengers to feel more comfortable and to maintain a constant height of the body. Valves are installed to regulate and supply compressed air to air and air springs.

종래 공기스프링에 공급되는 압축공기를 차체와 대차의 상대높이의 변동에 따라 조절하는 밸브의 구조는 제4도 내지 제5도에 도시한 바와같이, 차체(1)에 고정된 밸브본체(2)의 압축공기 유입구(3)와 밸브좌(4)사이에 스프링(5)에 의해 개폐판(6)을 탄설하고, 그 하부에는 수직통공(7')이 천설된 밸브봉(7)을 상하 접동가능하게 설치하여 대차(8)에 턴버클(9)로써 연결된 요동레버(10)의 선단 그 하단부를 핀으로 연결한 것으로 차체와 대차의 상대높이의 변동에 따른 요동레버(10)의 요동에 의해 밸브봉(7)을 승강시키므로써 작동하여, 차체와 대차의 상대 높이가 낮을 경우에는 밸브봉(7)이 상승하여 헤드(11)가 개폐판(6)을 밀어 올려서 공급구(12)를 통해 압축공기를 공기스프링에 공급하고, 상대높이가 높을 경우에는 밸브봉(7)이 하강하면서 개폐판(6)을 복귀시킴과 동시에 헤드(11)가 공급구(12)와 통공(7')을 연통시켜 공기스프링에 공급되었던 압축공기를 배기공(13)을 통해 배출하므로써 차체와 대차의 상대 높이 변동에 따른 완충과 그 높이를 조절하는 것이었다.Conventionally, the valve body for adjusting the compressed air supplied to the air spring according to the variation of the relative height of the vehicle body and the bogie is a valve body 2 fixed to the vehicle body 1, as shown in FIGS. The opening and closing plate 6 is installed between the compressed air inlet 3 and the valve seat 4 by the spring 5, and the valve rod 7 on which the vertical through hole 7 'is installed is slid up and down. The lower end of the swing lever 10 connected to the trolley 8 by a turnbuckle 9 is connected to the bogie 8 with a pin. The valve is caused by the swing of the swing lever 10 according to the change in the relative height of the body and the bogie. It operates by elevating the rod 7 so that when the relative height of the vehicle body and the bogie is low, the valve rod 7 is raised so that the head 11 pushes up the opening and closing plate 6 to be compressed through the supply port 12. Air is supplied to the air spring, and when the relative height is high, the valve rod 7 descends and the opening and closing plate 6 is returned. At the same time, the head 11 communicates with the supply port 12 and the through hole 7 'to discharge the compressed air that has been supplied to the air spring through the exhaust hole 13. Was to regulate.

그러나 상기 구조에 있어서 밸브봉(7)의 헤드(11)가 제5도에 도시한 바와같이 공급구(12)의 높이 및 밸브좌(4)의 높이와 동일한 높이로 되어 있기 때문에 밸브좌(4) 또는 공급구(12)의 개폐를 위해서는 밸브봉(7)의 스트로크가 길어야 하므로 결국 상대높이 차가 큰 경우 즉 차체의 진동이 큰 경우에만 작동되며 또한 진동개시점으로부터 상당시간 후로부터 작동이 되므로 절적한 완충효과를 얻을 수 없는 폐단이 있었다. 따라서 본 고안은 이러한 공래의 폐단을 제거하고 차체의 미소한 진동에도 즉각적으로 작동하여 완충작용을 하므로써 보다 안락한 승차감을 제공할 수 있도록 하려는 것으로 이를 첨부 도면에 따라서 상세히 설명하면 다음과 같다.However, in the above structure, since the head 11 of the valve rod 7 has the same height as the height of the supply port 12 and the height of the valve seat 4 as shown in FIG. 5, the valve seat 4 In order to open or close the supply port 12, the stroke of the valve rod 7 must be long, so it is only activated when the relative height difference is large, that is, when the vibration of the vehicle body is large. There was a lung that could not achieve a buffering effect. Therefore, the present invention is intended to provide a more comfortable ride by removing the conventional closed end and immediately acting on a slight vibration of the car body to provide a cushioning effect.

즉, 본 고안은 제1도 내지 제3도에 도시한 바와 같이, 차체(1)에 고정된 밸브본체(2)의 압축공기 유입구(3)에 연통된 밸브좌(4)를 상시 폐쇄하는 개폐판(6)을 스프링(5)으로 탄설하고, 그 하부에 수직통공(7')이 천설된 밸브봉(7)을 상하 접동가능하게 설치하여 대차(8)에 턴버클(9)로써 연결된 요동레버(10)의 선단에 핀으로 연결하여 차체(1)의 진동에 따라 밸브좌(4)와 통공(7')을 공급구(12)에 선택적으로 연통시키는 통상의 것에 있어서, 상기 밸브봉(7)의 헤드(11) 상단에 환형 노치(14)를 형성하여 상기 밸브좌(4)와 공급구(12)의 높이의 절반이 되는 돌환(15)가 형성되도록 하여서 된 것이다.That is, according to the present invention, as shown in FIGS. 1 to 3, the opening and closing for normally closing the valve seat 4 communicated with the compressed air inlet port 3 of the valve body 2 fixed to the vehicle body 1 is shown. The swinging lever connected with the turnbuckle 9 to the trolley 8 by installing the valve 6 with a spring 5 and installing a valve rod 7 with a vertical through hole 7 'installed on the bottom thereof so as to be movable upward and downward. The valve rod 7 in the conventional one which is connected to the tip of the pin 10 with pins and selectively communicates the valve seat 4 and the through hole 7 'with the supply port 12 in response to the vibration of the vehicle body 1. An annular notch 14 is formed on the top of the head 11 so as to form a projection 15 which is half the height of the valve seat 4 and the supply port 12.

이와같이 구성된 본 고안은 제2도에 도시한 바와같이 차체(1)와 대차(8)의 상대높이 변동 즉 차체(1)의 상하 진동에 따라 밸브좌(4)와 통공(7')을 공급구(12)에 선택적으로 연통시켜 공기스프링(미도시)에 압축공기를 공급하고 배출시키므로써 완충작용을 하는 것인바, 상기 밸브봉(7)의 헤드(11)상단에 환형노치(14)가 형성되어 있으므로 미소한 진동에도 민감하게 작동하여 보다 효과적인 완충작용을 할 수 있는 것이다.According to the present invention configured as described in FIG. 2, the valve seat 4 and the through hole 7 'are supplied in accordance with the relative height variation of the vehicle body 1 and the bogie 8, that is, the vertical vibration of the vehicle body 1. It selectively communicates with (12) to supply and discharge compressed air to an air spring (not shown) to buffer the bar. An annular notch 14 is formed on the top of the head 11 of the valve rod 7. Because it is so sensitive to the slight vibrations can be more effective buffering effect.

즉, 제2a도와 같이 차체(1)와 대차(8)가 정상위치에 있을 경우 즉 진동이 없을 경우에는 스프링(5)에 의하여 탄설된 개폐판(6)에 의해 밸브좌(4)가 폐쇄되어 완충작용은 이루어지지 않는다.That is, as shown in FIG. 2A, when the vehicle body 1 and the bogie 8 are in the normal position, that is, when there is no vibration, the valve seat 4 is closed by the opening / closing plate 6 installed by the spring 5. There is no buffering.

다음 차체(1)가 하향진동하기 시작하면 제2b도와 같이 요동레버(10)가 요동하면서 밸브봉(7)을 끌어올리게 되고 헤드(11)가 개폐판(6)을 밀어 올려 밸브좌(4)를 개방하여 공급구(12)와 연통시키므로 유입구(3)에서 유입된 압축공기가 공기스프링(미도시)에 공급되어 완충이 이루어지기 시작하며, 진동폭이 커지면 제2c도와 같이 밸브좌(4)의 개방도가 커지면서 다량의 압축공기가 공급되어 완충작용을 하게 된다.Next, when the vehicle body 1 starts to vibrate downward, the swing lever 10 swings and lifts the valve rod 7 as shown in FIG. 2B, and the head 11 pushes the opening and closing plate 6 to open the valve seat 4. Is opened to communicate with the supply port 12, so that the compressed air introduced from the inlet (3) is supplied to the air spring (not shown) to start the buffering, and as the vibration width increases, as shown in FIG. As the opening degree increases, a large amount of compressed air is supplied to buffer the air.

다시 차체가 상향 진동하기 시작하면 제2d도와 같이 요동레버(10)가 요동하면서 밸브봉(7)을 당기게 되고 이때 밸브헤드(11)에 의한 압상력이 해제되므로 개페판(6)이 복귀되면서 밸브좌(4)가 폐쇄되고, 헤드(11)가 하강하여 공급구(12)와 통공(7')을 연통시키게 되어 공기스프링에 공급되었던 압축공기는 통공(7')과 배기공(13)을 통해 방출되기 시작하며, 그 진동폭이 커짐에 따라 제2e도와 같이 통공(7')과 공급구(12)의 통로가 확대되므로 압축공기가 급속히 방출되어 신속히 원상복귀하게 된다.When the vehicle body starts to oscillate upward again, as shown in FIG. 2D, the swing lever 10 swings and pulls the valve rod 7. At this time, the pressing force by the valve head 11 is released, so that the opening plate 6 is returned. The left side 4 is closed and the head 11 is lowered to communicate the supply port 12 with the through hole 7 'so that the compressed air supplied to the air spring opens the through hole 7' and the exhaust hole 13. As it starts to be discharged through, the passage of the through hole 7 'and the supply port 12 is enlarged as the vibration width increases, so that the compressed air is rapidly released and returns to the original state quickly.

본 고안은 이와 같은 반복작동에 의해 완충작용을 하는 것인바, 밸브헤드(11)에 환형 노치(14)를 형성하여 그 돌환(15)의 높이가 밸브좌(4)와 공급구(12) 높이의 절반이 되도록 하였으므로 차체의 미소한 진동에도 완충작용이 이루어져서 승객이 보다 안락한 승차감을 느낄 수 있는 효과가 있는 것이다.The present invention is to act as a buffer by such a repeating operation, the annular notch 14 is formed in the valve head 11 so that the height of the ring 15 is the valve seat 4 and the supply port 12 height Since it is made to be half of the cushioning effect is made even in the slight vibration of the car body has the effect that the passengers can feel a more comfortable ride.
