본 고안은 자동차의 차고조정장치에 관한 것으로, 더욱 상세하게는 동력원으로 브레이크 부스터를 이용하여 차체를 지탱하고 있는 댐퍼를 승강시켜 차체의 높이를 조절할 수 있도록 한 자동차의 차고조정장치에 관한 것이다.The present invention relates to a vehicle height adjustment device, and more particularly to a vehicle height adjustment device that can adjust the height of the vehicle body by raising and lowering the damper holding the vehicle body using a brake booster as a power source.

일반적으로 차체의 높이는 일반 포장도로에서는 공기 저항이 작고 조정 안정성을 좋게 하기 위하여 차고를 낮추고, 험한 길에서는 주파성을 좋게 하기 위하여 차고를 높이는 것이 유리한데 이와같이 자동차의 차고를 조절하기 위한 것이 차고조정장치이다.In general, the height of the car body is advantageous to lower the height of the garage to improve the stability of adjustment and to improve the stability of the pavement on the general pavement, and to increase the height of the garage to improve the frequency on rough roads. .

이와같은 종래의 예로서, 예시도면 제1도는 종래의 차고조정장치의 구성도를 나타낸 것이다.As such a conventional example, Figure 1 shows a schematic view of a conventional garage adjustment apparatus.

도시한 바와 같이, 높이가 조정되는 댐퍼(1)가 차체와 바퀴사이에 설치되고, 자동차의 전자제어장치인 ECU(2)의 제어에 의해 상기 댐퍼(1)의 높이를 제어할 수 있는 HCU(Hight control unit)(3)가 유압모터(4) 및 구동풀리 등으로 구성되어 ECU(2)에 연결되며, 상기 ECU(2)를 조작할 수 있는 스위치(5)가 운전석 주변이나 계기판에 설치되어 이루어진다.As shown in the drawing, a damper 1 whose height is adjusted is installed between the vehicle body and the wheels, and the HCU capable of controlling the height of the damper 1 under the control of the ECU 2, which is an electronic controller of an automobile ( Hight control unit (3) is composed of a hydraulic motor (4) and a drive pulley and connected to the ECU (2), a switch (5) for operating the ECU (2) is installed around the driver's seat or instrument panel Is done.

미설명부호 6은 넌리턴밸브, 7은 리저버이다.Reference numeral 6 is a non-return valve, and 7 is a reservoir.

그런데 이와 같은 종래의 차고조정장치의 HCU는 상당히 고가이므로 고급차종에만 적용되고 있으며, 일반적인 승용차나 소형차에는 적용하기 힘든 문제가 있었다.However, the HCU of the conventional garage adjustment apparatus is very expensive, so it is applied only to high-end models, and it is difficult to apply to general passenger cars or small cars.

본 고안은 이와 같은 종래의 문제점을 감안하여 고안한 것으로, 차고조정장치의 동력원으로 유압식 브레이크장치에 설치되어 높은 유압을 발생시키는 부스터를 이용하여 댐퍼를 승강시킬 수 있도록 하므로써 차고조정장치의 설치비용을 절감시켜 일반적인 승용차나 소형차에도 차고조정장치를 장치할 수 있도록 하는데 본 고안의 목적이 있다.The present invention has been devised in view of such a conventional problem, and the installation cost of the garage adjustment device can be increased by allowing the damper to be raised and lowered by using a booster that generates high oil pressure installed in the hydraulic brake device as a power source of the garage adjustment device. It is an object of the present invention to reduce the height can be installed in the general car or compact car height adjustment device.

상기와 같은 목적을 실현하기 위한 본 고안은 이미 차량에 설치되어 있는 부스터를 이용한 브레이크 장치에 부가하여 ECU의 신호를 받아 차고조정기능을 선택 및 제어할 수 있는 HCU와 상기 HCU에 신축 가능한 댐퍼를 설치하여 스위치조작에 따라 ECU의 전기적인 신호가 HCU를 제어하여 평상시에는 브레이크페달의 답력이 브레이크에 장치에 공급되어 휠실린더의 작동으로 제동력이 발생되며, 차고조정시에는 브레이크페달의 답력이 댐퍼에 유도되어 댐퍼의 길이를 신축시킬 수 있도록 이루어진 것이다.The present invention for achieving the above object is installed in addition to the brake device using a booster already installed in the vehicle to install an HCU capable of selecting and controlling the garage adjustment function in response to the signal from the ECU and the flexible damper on the HCU In response to the switch operation, the ECU's electrical signal controls the HCU, and normally, the pedal pedal's power is supplied to the brake to the device, and the braking force is generated by the wheel cylinder's operation. It is made to stretch the length of the damper.

이하 상기한 바와 같은 본 고안에 의한 자동차의 차고조정장치를 첨부도면에 의거하여 보다 상세히 설명한다.Hereinafter, the vehicle height adjusting apparatus of the present invention as described above will be described in more detail based on the accompanying drawings.

본 고안은 ECU(10)의 신호를 받아 차고조정기능을 선택 및 제어할 수 있는 HCU(12)가 브레이크 페달(14)의 답력을 큰 유압으로 발생시키는 부스터(16)의 출력부에 설치되고, 상기 HCU(12)에 신축 가능한 댐퍼(18)가 파이프(20)를 매개로 연결됨과 더불어 상기 HCU(12)에 앞, 뒤바퀴의 제동을 위한 휠실린더(22)가 파이프(20)를 매개로 연결되며, 상기 HCU(12)를 작동시킬 수 있는 선택/제어 스위치(30)가 ECU(10)에 연결되어 설치된 구조로 되어 있다.According to the present invention, the HCU 12 capable of selecting and controlling the garage adjustment function in response to a signal from the ECU 10 is installed at the output of the booster 16 which generates a large hydraulic pressure of the brake pedal 14, The flexible damper 18 is connected to the HCU 12 via the pipe 20, and the wheel cylinder 22 for braking the front and rear wheels is connected to the HCU 12 via the pipe 20. Is connected, the selection / control switch 30 capable of operating the HCU (12) is connected to the ECU 10 has a structure installed.

예시도면 제2도는 본 고안에 따른 차고조정장치의 구성도로서, 상기 HCU(12)는 부스터(16)에서 공급되는 유압을 휠실린더(22)와 댐퍼(18)측으로 선택할 수 있는 솔레노이드밸브(24)와 댐퍼(18)에 공급된 유압이 언로딩상태를 유지할 수 있는 넌리턴밸브(26)와 유압을 복귀시켜 댐퍼(18)를 수축시킬 수 있는 리턴밸브(28)등으로 구성된다.Exemplary Drawing 2 is a configuration diagram of a height adjusting device according to the present invention, the HCU 12 is a solenoid valve 24 that can select the hydraulic pressure supplied from the booster 16 to the wheel cylinder 22 and the damper 18 side. ) And a non-return valve 26 capable of maintaining the unloading state of the hydraulic pressure supplied to the damper 18, and a return valve 28 capable of retracting the hydraulic pressure to contract the damper 18.

이하 본 고안의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

평상시에는 선택/제어 스위치(30)가 브레이크장치로 선택되어 있어 브레이크 페달(14)의 답력이 앞바퀴 및 뒷바퀴의 휠실린더(22)에 작동되어 감속 및 제동이 이루어지며, 차고높이를 조정하고자 하는 경우에는 선택/제어 스위치(30)를 조작하면 부스터(16)의 큰 유압이 상기 스위치의 제어신호를 입력받은 ECU(10)가 신축가능한 댐퍼(18)측으로 공급되도록 솔레노이드밸브(24)를 제어하여 절환시키며 이때 브레이크 페달(14)의 답력은 부스터(16)를 통해 증대되어 댐퍼(18)를 상승시키게 된다.When the selection / control switch 30 is normally selected as a brake device, the pedal pedal 14 acts on the wheel cylinders 22 of the front wheel and the rear wheel to decelerate and brake, and to adjust the height of the garage. When the selection / control switch 30 is operated, the large hydraulic pressure of the booster 16 is controlled by switching the solenoid valve 24 so that the ECU 10 receiving the control signal of the switch is supplied to the flexible damper 18. At this time, the pedal effort of the brake pedal 14 is increased through the booster 16 to raise the damper 18.

이후 원하는 높이까지 차고를 높인 후 선택/제어 스위치(30)를 이용하여 브레이크 장치측으로 솔레노이드밸브(24)를 절환시키면 HCU(12)의 넌리턴밸브(26)에 의해 유압을 언로딩 상태로 고정시켜 설정높이를 유지하게 된다.After raising the garage to a desired height and then switching the solenoid valve 24 to the brake unit by using the select / control switch 30, the hydraulic pressure is fixed in the unloading state by the non-return valve 26 of the HCU 12. It will maintain the set height.

한편, 차고의 낮추고자하는 경우에 선택/제어 스위치(30)를 하강으로 조작하면 HCU(12)의 리턴밸브(28)가 작동되어 유압을 복귀시켜 댐퍼(18)의 높이가 수축되도록 한다.On the other hand, when the garage is to be lowered, when the selection / control switch 30 is operated downward, the return valve 28 of the HCU 12 is operated to return the hydraulic pressure so that the height of the damper 18 is contracted.

이상에서 상세히 설명한 바와 같이, 본 고안에 의한 자동차의 차고조정장치에 따르면 차고조정장치의 동력원을 브레이크 장치의 부스터에서 발생되는 유압을 이용하므로 설치비용이 절감되어 일반 승용차 및 소형차에도 차고조정장치를 보급할 수 있는 효과를 얻을 수 있다.As described above in detail, according to the vehicle height adjusting device of the present invention, the power source of the height adjusting device uses the hydraulic pressure generated from the booster of the brake device, thereby reducing the installation cost and spreading the height adjusting device to general passenger cars and small cars. The effect can be obtained.
