도 1은 본 고안의 실시예에 따른 차고높이 조절장치도1 is a height adjustment apparatus according to an embodiment of the present invention

이하 본 고안을 첨부한 도면을 참조하여 본 고안의 바람직한 실시예의 동작을 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the operation of the preferred embodiment of the present invention will be described in detail.

도 1은 본 고안의 실시예에 따른 차고높이 조절장치도이다.1 is a height adjustment apparatus according to an embodiment of the present invention.

차고조절스위치 10은 운전자가 조작하기 편리한 위치, 예를 들어 운전석도어나 운전석 전면에 설치되어 온시킬 경우 차고의 높이를 상승시키기 위한 키신호를 발생하고, 오프시킬 경우 차고의 높이를 하강시키는 키신호를 발생한다. 제어부(ECU : Electronic Control Unit) 12는 상기 차고조절스위치 10으로부터 발생한 차고선택키신호에 따라 차고를 상승시키거나 하강시킬 수 있도록 각 바퀴의 유압제어신호를 출력한다. 유압발생부 14는 파워스티어링(Power Stearing) 유압펌프로 구현할 수 있으며, 유압을 발생한다. 멀티제어밸브 16은 상기 유압발생부 14로부터 발생된 유압이 안정되게 공급되도록 제어한다. 4개의 압력제어밸브 18, 20, 22, 24는 상기 멀티제어밸브 16으로부터 공급되는 유압을 상기 제어부 12의 유압제어신호에 의해 각 바퀴의 작동유압을 제어한다. 4개의 유압 액츄에이터 26, 28, 30, 32는 상기 4개의 압력제어밸브 18, 20, 22, 24의 각 작동유압에 따라 전체적으로 차고를 높이거나 하강시키는 기능을 수행한다.The garage control switch 10 generates a key signal for increasing the height of the garage when the driver is installed at a position convenient for the driver, for example, on the driver's door or the front of the driver's seat. Occurs. An electronic control unit (ECU) 12 outputs a hydraulic control signal of each wheel to raise or lower the garage according to the garage selection key signal generated from the garage control switch 10. The hydraulic generator 14 may be embodied as a power steering hydraulic pump and generates hydraulic pressure. The multi control valve 16 controls the oil pressure generated from the oil pressure generating unit 14 to be stably supplied. The four pressure control valves 18, 20, 22, and 24 control the hydraulic pressure of each wheel by the hydraulic pressure control signal of the controller 12 for the hydraulic pressure supplied from the multi control valve 16. The four hydraulic actuators 26, 28, 30 and 32 perform a function of raising or lowering the garage as a whole in accordance with the respective hydraulic pressures of the four pressure control valves 18, 20, 22 and 24.

상술한 도 1을 참조하여 본 고안의 바람직한 일 실시예의 동작을 상세히 설명한다Referring to Figure 1 described above will be described in detail the operation of one preferred embodiment of the present invention

자동차의 운전자가 시동을 걸게되면 파워스티어링 유압펌프로 이루어진 유압발생부 14에서 유압을 발생한다. 이때 멀티제어밸브 16에서는 유압발생부 14로부터 발생한 유압을 4개의 압력제어밸브 18, 20, 22, 24로 안정하게 공급하도록 제어한다. 상기 멀티제어밸브 16은 메인릴리프밸브, 메인체크밸브, 오버렛체크밸브, 흐름제어밸브, 페일세이프밸브등으로 구성되어 있다. 메인릴리프밸브는 오일공급압이 예를 들어 약 100kgf/㎠이상이 되면 일부 오일 유량을 리턴측에 릴리프한다. 메인체크밸브는 라인에서 흐름제어밸브 방향으로 오일을 흘리고 역방향으로 흐르지 않도록 역지막으로 되어 있다. 오버렛 체크밸브는 공급압응동형의 개폐밸브 공급유압이 일정압, 예를 들어 51kgf/㎠이상에서 개방되고, 일정압 이하에서 닫히게 되면 엔진 오프시에 유압을 유지한다. 흐름제어밸브는 엔진시동시에 메인 통로를 닫고 바이패스 통로의 오리피스에서 완만하게 오일공급압을 시작하고 그후 메인 통로를 열어주어 엔진시동시에 차고의 급변을 방지하도록 한다. 페일 세이프밸브는 전기계통에 이상이 발생하였을 경우 오일의 통로를 새로 바꾸어 급격한 차고의 변화를 방지하여 안정성을 유지하도록 한다. 이와같이 유압발생부 14에서 유압이 발생되고 있는 상태에서 비포장도로나 포장도로의 과속방지턱등이 있는 도로를 주행할 시 운전자는 운전석 전면에 설치되어 있는 차고조절스위치 10을 조작하여 차고조절스위치 10을 온시키게 된다. 이때 제어부 12는 압력을 상승시키기 위한 제어신호를 발생하여 4개의 압력제어밸브 18, 20, 22, 24로 각각 인가한다. 상기 4개의 압력제어밸브 18, 20, 22, 24는 항공기에 사용하는 서보밸브같이 높은 응답성을 가진 파일럿형 비례전자 압력제어밸브를 사용하여 구현할 수 있다. 그러면 4개의 압력제어밸브 18, 20, 22, 24에서는 상기 멀티제어밸브 16으로부터 유로관 34를 통해 공급되는 유압을 각 바퀴 축에 연결된 4개의 엑츄에이터 26, 28, 30, 32로 각각 인가한다. 이로 인해 4개의 엑츄에이터 26, 28, 30, 32는 압력이 인가되므로 내부에 구비된 실린더내의 피스톤이 상부로 밀리게 되어 차고를 상승시키게 된다. 그러나 포장도로와 같이 평탄한 도로를 주행할 시에 운전자는 차고조절스위치 10을 조작하여 오프시키면 압력을 하강시키기 위한 제어신호를 4개의 압력제어밸브 18, 20, 22, 24로 인가한다. 그러면 4개의 압력제어밸브 18, 20, 22, 24는 각 바퀴축에 연결된 4개의 엑츄에이터 26, 28, 30, 32로 인가되는 유압을 차단하므로 4개의 엑츄에이터 26, 28, 30, 32는 실린더내의 피스톤이 하부로 밀리게 되어 차고를 하강시키게된다.When the driver of the vehicle starts, the oil pressure is generated in the oil pressure generating unit 14 formed of the power steering hydraulic pump. In this case, the multi control valve 16 controls the hydraulic pressure generated from the hydraulic generator 14 to be stably supplied to the four pressure control valves 18, 20, 22, and 24. The multi control valve 16 includes a main relief valve, a main check valve, an overflow check valve, a flow control valve, a fail safe valve, and the like. The main relief valve relieves some oil flow rate on the return side when the oil supply pressure is, for example, about 100 kgf / cm 2 or more. The main check valve has a check valve to prevent oil from flowing in the direction of the flow control valve in the direction of the line. The overflow check valve maintains the hydraulic pressure when the engine is turned off when the supply pressure actuated on-off valve supply hydraulic pressure is opened at a constant pressure, for example, 51 kgf / cm 2 or more, and closed at a constant pressure or less. The flow control valve closes the main passage at engine start and starts the oil supply pressure gently at the orifice of the bypass passage and then opens the main passage to prevent sudden changes in the garage at engine start. Fail-safe valve is to maintain the stability by preventing the sudden change of the garage by changing the passage of the oil in case of abnormality in the electrical system. Thus, when driving on the road with the speed bumps on the unpaved road or the pavement while the oil pressure is generated in the oil pressure generating unit 14, the driver operates the garage control switch 10 installed in the front of the driver's seat to turn on the garage control switch 10. Let's go. At this time, the control unit 12 generates a control signal for increasing the pressure and applies it to the four pressure control valves 18, 20, 22, 24, respectively. The four pressure control valves 18, 20, 22, and 24 may be implemented using a pilot type proportional electromagnetic pressure control valve having high responsiveness such as a servo valve used in an aircraft. Then, the four pressure control valves 18, 20, 22, and 24 apply hydraulic pressure supplied from the multi control valve 16 to the four actuators 26, 28, 30, and 32 respectively connected to the wheel shafts. As a result, four actuators 26, 28, 30, and 32 are applied with pressure, thereby causing the piston in the cylinder provided there to be pushed upward to raise the garage. However, when driving on a flat road such as a pavement, the driver applies a control signal to the four pressure control valves 18, 20, 22, and 24 to lower the pressure when the driver turns off the garage control switch 10. The four pressure control valves 18, 20, 22, and 24 shut off the hydraulic pressure applied to the four actuators 26, 28, 30, and 32 connected to each wheel axle, so that the four actuators 26, 28, 30, and 32 are pistons in the cylinder. This pushes down to lower the garage.

상술한 바와 같이 본 고안은, 자동차주행중에 비포장도로와 같은 평탄하지 않은 도로가 나타날 시 운전자가 운전석에 설치되어 있는 차고조절스위치를 온시켜 차고의 높이를 상승시키므로, 차제 하부가 노면에 부딪침을 방지할 수 있어 차량의 손상을 방지할 수 있는 이점이 있다.As described above, the present invention raises the height of the garage by turning on the garage control switch installed in the driver's seat when an uneven road such as an unpaved road appears while driving, thus preventing the lower part of the vehicle from hitting the road surface. There is an advantage that can be prevented to damage the vehicle.
