To operate the solenoid 71 of the solenoid valve 37.
상기와 같이 솔레노이드(71)가 작동함에 따라 플런저(73)가 아래로 이동하고, 상기 플런저(73)에 연동하는 피스톤(69)도 하강하게 된다.As the solenoid 71 operates as described above, the plunger 73 moves downward, and the piston 69 which interlocks with the plunger 73 also descends.
따라서, 제2공기탱크(35)와 제1 및 제2압력조절밸브(39, 41)가 연통되어, 상기 솔레노이드밸브(37)를 통해 제2공기탱크(35)내의 공기가 제1 및 제2압력조절밸브(39, 41)로 공급된다.Accordingly, the second air tank 35 and the first and second pressure regulating valves 39 and 41 communicate with each other so that the air in the second air tank 35 passes through the solenoid valve 37. It is supplied to the pressure regulating valves 39 and 41.
이때, 상기 전자제어유니트(49)가 헛도는 바퀴측의 에어마스터로 압력을 조절하여 공기를 공급하도록 제1 및 제2압력조절밸브(39, 41)를 제어함에 따라 제1 또는 제2에어마스터(43, 45)가 동작하여 바퀴가 헛도는 것을 방지하기 위한 제동이 이루어진다.At this time, the electronic control unit 49 controls the first and second pressure regulating valves 39 and 41 to supply air by regulating the pressure to the air master on the wheel side where the electronic control unit is idle. The masters 43 and 45 operate to provide braking to prevent the wheels from spinning.
이상에서 설명한 바와 같이 본 발명에 따르면, 더블체크밸브를 사용하지 않고 앤티스핀 레귤레이션 장치를 구성함으로써 그 구성이 간단할 뿐만 아니라 조립하기가 쉬운 효과가 있다.As described above, according to the present invention, by configuring the anti-spin regulation device without using the double check valve, the configuration is not only simple but also easy to assemble.
