본 고안은 에어스프링 장착 차량에 있어서 승객의 승,하차에 편의를 도모하기 위한 에어스프링의 높낮이 조절장치에 관한 것으로서 보다 상세하게 설명하면, 에어탱크와 양측에 각각 설치되는 에어스프링이 동일 공기통로에 연결설치되는 3/2 웨이 마그네틱 밸브와 3/3 웨이 마그네틱 밸브에 의해 각각 연결되며, 상기 에어탱크와 양측 에어스프링이 마그네틱 밸브와 레벨링 밸브에 의해 연결되고, 상기 에어스프링이 파킹 브레이크의 작동시 작동토록 하여 에어탱크로부터 양측면 에어스프링에 유입되는 에어를 양측의 마그네틱 밸브가 설치되는 공기통로와 레벨링밸브가 설치되는 2개의 공기통로에 의해 유입 및 유출함으로써, 차량에 장착되는 에어스프링을 승객의 승,하차에 편의를 도모하기 위하여 에어스프링의 높낮이를 용이하게 조정토록 하며, 승차감의 변동없이 에어스프링의 승강 및 하강시의 작동시간을 현저히 감소시킬 수 있도록 한 에어스프링 장착 차량의 높낮이 조절장치에 관한 것이다.The present invention relates to a device for adjusting the height of the air spring for the convenience of passengers to get on and off in an air spring-equipped vehicle. More specifically, the air tank and the air springs installed on both sides of the air spring are installed in the same air passage. It is connected by a 3/2 way magnetic valve and a 3/3 way magnetic valve, respectively, and the air tank and both air springs are connected by a magnetic valve and a leveling valve, and the air spring is operated when the parking brake is operated. By inflowing and outflowing air from the air tank into the two side air springs through the air passages provided with both magnetic valves and the two air passages provided with the leveling valves, the air springs mounted on the vehicle can be lifted. Easily adjust the height of the air spring for convenience in getting off, The present invention relates to a device for adjusting the height of an air spring-equipped vehicle, which is capable of significantly reducing the operating time during lifting and lowering of the air spring without changing the riding comfort.
일반적으로 알려져 있는 에어스프링 장치는, 승차감을 향상시키는 에어스프링, 에어스프링에 유입되는 에어의 압력을 조절하는 서어지(surge)탱크, 에어를 분배하는 레벨링 밸브등으로 구성되며, 차량의 하중이 감소하여 차의 높이가 높아지면 레벨링 밸브가 작용하여 에어스프링내측의 공기가 방출되고, 하중이 증가하여 차 높이가 낮아지면 에어탱크에서 에어를 보충하여 차량의 높이를 일정하게 유지토록 하는 것이다.Generally known air spring device is composed of an air spring to improve the ride comfort, a surge tank to adjust the pressure of the air flowing into the air spring, a leveling valve for distributing the air, etc. As the height of the car increases, the leveling valve acts to release the air inside the air spring. When the load increases and the car height decreases, the air tank replenishes air to maintain the height of the vehicle.
이와같은 기술과 관련된 종래의 에어스프링 장착 차량의 높낮이 조정장치는, 컴프레셔(51)의 일측에 에어탱크(52)가 착설되고, 상기 에어탱크(51)와 양측으로 설치되는 에어스프링(56)(56')은 공기통로(57)(57')로서 연결되며, 상기 공기통로(57)에 3/2 마그네틱 밸브(53)와 레벨링 밸브(55)에 일체로 결합되는 덤프(DUMP)밸브(54)가 설치되고, 상기 레벨링 밸브(55)에 분기되는 공기통로(57')에 의해 에어스프링(56)(56')에 연결되어 에어스프링의 높이를 조절하는 구성으로 이루어진다.In the conventional air spring height adjusting device associated with such a technique, an air tank 52 is installed on one side of the compressor 51, and an air spring 56 installed on both sides of the air tank 51 ( 56 ′ is connected as air passages 57 and 57 ′, and a dump valve 54 integrally coupled to the air passage 57 with a 3/2 magnetic valve 53 and a leveling valve 55. ) Is installed and connected to the air springs 56 and 56 'by an air passage 57' branched to the leveling valve 55 to adjust the height of the air spring.
상기와 같은 에어스프링의 높이 조절장치는, 차량에 승객이 승,하차할때 차량 앞부분의 높이를 조절하여 승객의 승,하차 편의를 도모토록 닐링(KNEELING)시스템을 이용 에어스프링의 높낮이를 조절하며, 상기 닐링시스템의 작동시 3/2 마그네틱 밸브(53)가 작동하여 열리면서 덤프밸브(54)의 한쪽끝을 밀어 레벨링 밸브(55)의 레버위치에 관계없이 에어스프링(56)(56')내의 공기가 배출되어 차량의 높이가 낮아지게 되고, 역으로 작동하면 차량의 높이가 올라가게 되는 것이다.The above-mentioned height adjustment device of the air spring, by adjusting the height of the front part of the vehicle when the passengers get on and off the vehicle, adjusts the height of the air spring using the Domotolock KNELING system In operation of the niling system, the 3/2 magnetic valve 53 is operated to open and push one end of the dump valve 54 to operate in the air springs 56 and 56 'regardless of the lever position of the leveling valve 55. The air is exhausted and the height of the vehicle is lowered, and when operated in reverse, the height of the vehicle is increased.
그러나, 상기와 같은 장치로 에어스프링(56)(56')의 높,낮이가 조절되지만 에어스프링(56)(56')에 공기의 공급과 배기시간이 과다하게 걸리는 단점이 있으며, 이를 개선하고자 공기통로 배관의 굵기를 확대할 경우 차량주행시 도로여건에 너무 민감하게 작용하여 승차감에 악 영향을 초래하게 되는 문제점이 있는 것이다.However, although the height and height of the air springs 56 and 56 'are controlled by the above device, the air springs 56 and 56' have a disadvantage in that excessive air supply and exhaust time are taken. In order to increase the thickness of the air passage pipe, there is a problem that it is too sensitive to the road conditions when driving the vehicle, causing a bad effect on the ride comfort.
