본 발명은 철도차량의 운전실 전면창 외면을 닦는 와이퍼를 구동시키는 철도차량을 와이퍼 구동시스템에 관한 것이다.The present invention relates to a wiper drive system for a railway vehicle for driving a wiper for wiping the outer surface of a cab front window of a railway vehicle.

이러한 기술과 관련된 종래의 철도차량용 와이퍼 구동시스템은 제4도와 같이 구성되어 있다.The conventional wiper drive system for railway vehicles related to this technique is constructed as shown in FIG.

여기서는 5/2-웨이밸브인 트랜스퍼밸브(TRANSFER VALVE)(10)의 공급라인(P)에는 유량제어밸브인 콘트롤러 스위치(CONTROLER SWITCH)(11)와 필터(FILTER)(12)가 연결되고 상기 트랜스퍼밸브(10)의 작업라인(A)(B)과 제어라인(Y)(Z)에는 공압의 실린더(20)가 연결되며, 상기 트랜스퍼밸브(100)작동에 의해 피스톤(PISTON)(21)이 실린더(CYLINDER)(20)내에서 좌우로 유동가능케 구성되어 있다.Here, the supply line P of the transfer valve 10, which is a 5 / 2-way valve, is connected to a controller switch 11 and a filter 12, which are flow control valves, and are connected to the transfer line P. A pneumatic cylinder 20 is connected to the work line A, B and the control line Y, Z of the valve 10, and the piston 21 is operated by the transfer valve 100. The cylinder CYLINDER 20 is configured to be movable from side to side.

상기 실린더(20)의 피스톤(21)에는 랙(RACK)(22)이 형성되어 있고 이 랙(22)에 와이퍼(WIPER)(도시하지 않음)가 장착되는 브레이드 아암(BLADE ARM)(24)이 장착된 반달형의 피니언(PININ)(23)이 맞물려 있다.The piston 21 of the cylinder 20 has a rack 22 formed therein and a blade arm 24 having a wiper (not shown) mounted thereon. The mounted half moon pinion 23 is engaged.

이러한 종래의 철도차량용 와이퍼 구동시스템은 운전자가 콘트롤러 스위치(11)를 조작하므로 압축공기가 필터(12)를 경유하여 트랜스퍼밸브(10)에 들어간다. 이때 1단계로 트랜스퍼밸브(10)의 공급라인(P)와 작업라인(B)가 연결된 상태로서 실린더(20)의 작업라인(B)측에 공기압이 가해져 피스톤(21)이 좌측으로 이동하고 이에따라 피스톤(21)의 랙(22)에 맞물린 피니언(23)이 회전하므로서 브레이드아암(24)이 우측으로 회전된다.In this conventional railway vehicle wiper drive system, the driver operates the controller switch 11 so that the compressed air enters the transfer valve 10 via the filter 12. At this time, the supply line (P) and the work line (B) of the transfer valve 10 is connected in the first step, the air pressure is applied to the work line (B) side of the cylinder 20, the piston 21 moves to the left and accordingly As the pinion 23 engaged with the rack 22 of the piston 21 rotates, the braid arm 24 rotates to the right.

상기 실린더(20)내의 피스톤(21)이 제어라인(Y)점을 통과하면 실린더(20) 작업라인 (B)측의 제어라인(Y)를 따라 신호가 가해져 트랜스퍼밸브(10)의 작업라인(A)와 배기라인 (R)이 연결되고 작업라인(B)는 공급라인(P)에 연결되므로 실린더(20) 공급라인(P)와 작업라인(A)가 연결되고 작업라인(B)는 배기라인(R)에 연결되므로 실린더(20)의 작업라인(A)측에 공기압이 가해진다.When the piston 21 in the cylinder 20 passes the control line (Y) point, a signal is applied along the control line (Y) on the working line (B) side of the cylinder (20), so that the work line of the transfer valve (10) ( A) and the exhaust line (R) is connected and the work line (B) is connected to the supply line (P), so the cylinder 20 supply line (P) and the work line (A) is connected and the work line (B) is exhausted Since it is connected to the line (R), air pressure is applied to the work line (A) side of the cylinder (20).

실린더(20)의 작업라인(A)측에 공기압이 가해지면 2단계동작인 피스톤(21)이 우측으로 이동하고 이에따라 피스톤(21)이 랙(22)에 맞물린 피니언(23)이 회전하므로서 브레이드아암이 좌측으로 회전하게 된다.When air pressure is applied to the work line A side of the cylinder 20, the piston 21, which is a two-stage operation, moves to the right, whereby the braid arm rotates as the pinion 23, in which the piston 21 is engaged with the rack 22, rotates. Will rotate to the left.

상기 실린더(20)내의 피스톤(21)이 제어라인(Z)점을 통과하면 제어라인(Z)측의 제어라인(Z)을 따라 신호가 가해져 트랜스퍼밸브(10)의 작업라인(A)와 배기라인(R)이 연결되고 작업라인(B)는 공급라인(P)에 연결되므로 실린더(20)의 작업라인(B)측에 다시 공기압이 가해지게 된다.When the piston 21 in the cylinder 20 passes the control line Z point, a signal is applied along the control line Z on the control line Z side to exhaust the work line A and exhaust of the transfer valve 10. Since the line R is connected and the work line B is connected to the supply line P, air pressure is again applied to the work line B side of the cylinder 20.

상기한 작동이 순차적으로 순환되므로서 계속적으로 작동되는 것이다. 그러나, 이러한 종래의 철도차량용 와이퍼 구동장치는 수평왕복운동을 하는 공압의 실린더(20)은 각 운동을 하는 브레이드 아암(24)의 연결부가 랙(22)과 피니언(23)으로 구성되어 있기 때문에 결합부에 과도한 힘이 작용되어 피니언(23)의 마모 및 파손사고가 빈번하고 작동이 불안정하며, 소량주문 생산이 불가피하여 고가이면서도 품질이 안정되지 않아 실린더(20)의 취부나 누설사고가 잦고 정비 부품을 적기에 공급할 수 없는 것이었다.The above operation is continuously operated as it is sequentially cycled. However, such a conventional wiper drive device for railway vehicles is coupled to the pneumatic cylinder 20 for horizontal reciprocating motion because the connection portion of the braid arm 24 for each motion is composed of the rack 22 and the pinion 23. Excessive force is applied to the parts, causing frequent wear and breakage of the pinion 23 and unstable operation. Production of small quantities is inevitable, and the quality and stability are not stable. Could not supply timely.

또한, 브레이드아암(24)이 2개인 더블방식인 경우는 또 하나의 제어시스템이 필요하고 작동범위(각도)를 조정할 수 없는 것이었다.In addition, in the case of the double system having two braid arms 24, another control system was required and the operating range (angle) could not be adjusted.
