여기서, 상기 관로(11,12,13,14)는, 상기 공기탱크(1)와 솔레노이드밸브(5)를 연결하는 제1관로(11)와, 상기 솔레노이드밸브(5)에서 레벨링밸브(7) 및 공기작동밸브(8)를 통과하여 공기스프링(9)과 연결되는 제2관로(12)와, 상기 솔레노이드밸브(5)에서 컨트롤밸브(6)를 통과하여 공기작동밸브(8)에 연결되는 제3관로(13)와, 상기 컨트롤밸브(6)에서 공기작동밸브(8)와 공기스프링(9)사이의 제2관로(12)와 연결되는 제4관로(14)로 이루어져 있다.Here, the pipes (11, 12, 13, 14), the first pipe (11) connecting the air tank 1 and the solenoid valve (5), and the leveling valve (7) in the solenoid valve (5) And a second conduit 12 connected to the air spring 9 through the air operated valve 8, and a control valve 6 connected to the air operated valve 8 from the solenoid valve 5. And a fourth conduit 14 connected to the third conduit 13 and the second conduit 12 between the air operated valve 8 and the air spring 9 in the control valve 6.
한편, 상기 차속센서(2)로부터 전달된 신호에 의해 상기 전자제어유니트(4)가 차량을 주행상태로 판별하게 되면, 상기 솔레노이드밸브(5)와 레벨링밸브(7) 및 공기작동밸브(8)는 전자제어유니트(4)의 제어신호에 의해 각각 개방되게 되고, 이에 따라 상기 공기탱크(1)내의 압축공기는 상기 밸브(5,7,8)들과 제1관로(11) 및 제2관로(12)를 순차적으로 경유하여 공기스프링(9)으로 공급되게 된다.On the other hand, when the electronic control unit 4 determines the vehicle as a driving state by the signal transmitted from the vehicle speed sensor 2, the solenoid valve 5, the leveling valve 7 and the air operated valve 8 Are respectively opened by the control signal of the electronic control unit 4, so that the compressed air in the air tank (1), the valves (5, 7, 8), the first conduit (11) and the second conduit Via 12 is sequentially supplied to the air spring (9).
이와 같이, 차량이 주행상태일 때 상기 레벨링밸브(7)가 전자제어유니트(4)에 의해 개방되면, 상기 레벨링밸브(7)는 주행중인 차량의 상태에 따라 공기스프링(9)으로 공급되는 압축공기의 양을 조절하게 되며, 이로 인해 주행중인 차량의 차고는 항상 일정한 상태를 유지하게 된다.As such, when the leveling valve 7 is opened by the electronic control unit 4 when the vehicle is in a running state, the leveling valve 7 is compressed to be supplied to the air spring 9 according to the state of the vehicle being driven. The amount of air is controlled so that the vehicle's garage is always in a constant state.
그리고, 상기 전자제어유니트(4)가 차량을 주행상태로 판별하게 되면, 상기 컨트롤밸브(6)는 전자제어유니트(4)의 제어신호에 의해 밀폐되게 되고, 이로 인해 상기 공기스프링(9)으로 공급되던 압축공기가 제4관로(14)를 통해 컨트롤밸브(6)쪽으로 이동되더라도 밀폐된 컨트롤밸브(6)에 의해 솔레노이드밸브(5)쪽으로 역류되는 것이 방지되게 된다.When the electronic control unit 4 determines the vehicle as the driving state, the control valve 6 is sealed by the control signal of the electronic control unit 4, which leads to the air spring 9. Even if the compressed air supplied is moved to the control valve 6 through the fourth pipe 14, the flow back to the solenoid valve 5 is prevented by the sealed control valve 6.
한편, 상기 주차브레이크센서(3)로부터 전달된 신호에 의해 상기 전자제어유니트(4)가 차량을 주정차상태로 판별하게 되면, 상기 솔레노이드밸브(5)와 컨트롤밸브(6)와 공기작동밸브(8)는 전자제어유니트(4)의 제어신호에 의해 각각 개방되게 되고, 이에 따라 상기 공기탱크(1)내의 압축공기는 상기 밸브(5,6,8)들과 제1관로(11)와 제3관로(13)와 제4관로(14) 및 제2관로(12)를 순차적으로 경유하여 공기스프링(9)으로 공급되게 된다.On the other hand, when the electronic control unit 4 determines the vehicle to be parked by the signal transmitted from the parking brake sensor 3, the solenoid valve 5, the control valve 6 and the air operated valve 8 ) Is opened by the control signal of the electronic control unit 4, so that the compressed air in the air tank (1), the valves (5, 6, 8), the first pipe (11) and the third Via the pipeline 13, the fourth pipeline 14 and the second pipeline 12 in order to be supplied to the air spring (9).
그리고, 상기 전자제어유니트(4)가 차량을 주정차상태로 판별하게 되면, 상기 레벨링밸브(7)는 전자제어유니트(4)의 제어신호에 의해 밀폐되게 되고, 이로 인해 상기 공기스프링(9)으로 공급되던 압축공기가 제2관로(12)를 통해레벨링밸브(7)쪽으로 이동되더라도 밀폐된 레벨링밸브(7)에 의해 솔레노이드밸브(5)쪽으로 역류되는 것이 방지되게 된다.When the electronic control unit 4 determines that the vehicle is in a parked state, the leveling valve 7 is sealed by the control signal of the electronic control unit 4, which leads to the air spring 9. Even if the compressed air supplied is moved toward the leveling valve 7 through the second conduit 12, it is prevented from flowing back toward the solenoid valve 5 by the sealed leveling valve 7.
또한, 상기 전자제어유니트(4)에 의해 차량이 주정차상태로 판별되면 리어데크(도시않됨)의 하중에 따라 상기 컨트롤밸브(6)의 개방각도(개방정도)가 조절되게 되며, 이로 인해 상기 공기스프링(9)으로 공급되는 압축공기의 양은 컨트롤밸브(6)의 개방각도(개방정도)에 따라 제어되게 된다.In addition, when the vehicle is determined to be in the stopped state by the electronic control unit 4, the opening angle (opening degree) of the control valve 6 is adjusted according to the load of the rear deck (not shown), and thus the air The amount of compressed air supplied to the spring 9 is controlled according to the opening angle (opening degree) of the control valve 6.
즉, 상기 컨트롤밸브(6)의 개방각도는 리어데크의 하중과 비례되는데, 상기 리어데크의 하중이 무거울수록 컨트롤밸브(6)의 개방각도(개방정도)는 커지게 되고, 반대로 상기 리어데크의 하중이 가벼울수록 컨트롤밸브(6)의 개방각도(개방정도)는 작아지게 된다.That is, the opening angle of the control valve 6 is proportional to the load of the rear deck, and the heavier the load of the rear deck, the larger the opening angle (opening degree) of the control valve 6 becomes, and conversely, The lighter the load, the smaller the opening angle (opening degree) of the control valve 6 becomes.
이와 같이, 1톤 트럭의 차체후방에 압축공기를 이용한 후방차고조정장치를 설치하게 되면, 리어데크(화물적재함)에 많은 양의 화물을 적재한 후 노면이 고르지 못한 도로를 주행하더라도 후방차체의 높이가 본 발명에 따른 후방차고조정장치의 레벨링밸브(7)에 의해 자동적으로 조절되면서 차체와 노면의 접촉이 방지되게 되고, 이로 인해 탑승자의 승차감을 향상되면서 아울러 차체의 파손도 예방되게 된다.In this way, if the rear height adjustment device using compressed air is installed in the rear of the body of a 1 ton truck, even if the road is uneven road after loading a large amount of cargo in the rear deck (cargo load), the height of the rear body Is automatically adjusted by the leveling valve 7 of the rear height adjustment apparatus according to the present invention is prevented from contacting the vehicle body and the road surface, thereby improving the ride comfort of the occupant and also prevent the damage of the vehicle body.
또한, 주정차된 1톤 트럭의 리어데크로 화물을 적재시키거나 또는 리어데크에 적재된 화물을 내리는 작업을 할 경우 후방차체의 높이가 본 발명에 따른 후방차고조정장치의 컨트롤밸브(6)에 의해 작업하기 편한 높이로 자동 조절되게 되며, 이로 인해 작업자의 편의성이 그만큼 향상되게 된다.In addition, when loading cargo to the rear deck of a parked 1 ton truck or lowering the cargo loaded on the rear deck, the height of the rear vehicle body is controlled by the control valve 6 of the rear height adjustment device according to the present invention. It is automatically adjusted to a height that is easy to work, which improves the operator's convenience.
이상 설명한 바와 같이 본 발명에 의하면, 주행중인 트럭의 차체후방 높이가 후방차고조정장치의 레벨링밸브에 의해 자동적으로 조절되어 차체와 노면의 접촉이 방지되면서 탑승자의 승차감이 향상됨은 물론 차체의 파손이 예방되게 되고, 아울러 차량의 주정차시 리어데크의 높이가 적재된 화물의 중량에 따라 후방차고조정장치의 컨트롤밸브에 의해 자동적으로 조절되게 됨으로써 작업자의 편의성이 향상되는 효과가 있게 된다.As described above, according to the present invention, the height of the rear body of the running truck is automatically adjusted by the leveling valve of the rear height control device to prevent contact between the vehicle body and the road surface, thereby improving the riding comfort of the occupant and preventing damage to the vehicle body. In addition, the height of the rear deck is automatically adjusted by the control valve of the rear height control device according to the weight of the loaded cargo when the vehicle is stopped, thereby improving the convenience of the operator.
