본 발명은 차량의 차고 조정장치에 관한 것으로, 특히 쇽업소버(shock absorber)의 설치 높이를 쇽업소버몸체에 설치된 랙크(rack)와 너클브라켓트(knuckle bracket)에 설치된 피니언(pinion)을 매개로하여 차고를 조정할 수 있도록 된 차량의 차고 조정장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle height adjustment apparatus, and in particular, the height of the shock absorber may be set via a pinion installed on a rack and a knuckle bracket installed on the shock absorber body. It relates to a vehicle height adjustment device that can be adjusted.

일반적으로 차량에 설치되는 쇽업소버는 댐퍼(damper)라고도 불리우는 것으로, 차량주행시 서스펜션을 구성하는 스프링에 가해지는 충격으로 발생되는 고유진동을 흡수함으로써 승차감을 향상시키도록 하는 장치이다.Generally, a shock absorber installed in a vehicle is also called a damper, and is a device for improving ride comfort by absorbing natural vibration generated by an impact applied to a spring constituting a suspension when the vehicle is driven.

즉, 제3도에 도시된 것과 같이, 원통형상을 이룬 쇽업소버몸체(101)의 외주면 상부에 스프링시이트(spring seat,102)가 용접으로 고정되고 하부면에는 차체에 연결고정시키기 위한 너클브라켓트(103)가 용접되어, 상기 스프링시이트(102)을 매개로 스프링(도시안됨)을 끼워 고정시킴으로써, 이 스프링에서 차체에 가해지는 충격을 흡수토록 되어있다.That is, as shown in FIG. 3, a spring seat 102 is fixed to the upper portion of the outer circumferential surface of the shock absorber body 101 having a cylindrical shape by welding, and a knuckle bracket for fixing the lower surface to a vehicle body. 103 is welded to fix a spring (not shown) through the spring sheet 102 to absorb the shock applied to the vehicle body in the spring.

한편, 차량용 쇽업소버(104)는 차량의 운행조건, 예컨대 승객이 많이 탑승하거나 적재시킨 화물이 지나치게 많을 경우 차체가 수평을 유지하지 못하고 한쪽으로 기울게 되는데 이러한 현상이 반복적으로 지속되면 한쪽 스프링으로 하중이 집중되므로 하중이 집중되는 쪽에 설치된 스프링시이트(102)에 처짐이 발생되는 경우가 있다.On the other hand, the vehicle shock absorber 104 is inclined to one side of the vehicle body is not leveled when the operating conditions of the vehicle, for example, a lot of passengers boarding or loading a lot of load, if this phenomenon is repeated repeatedly the load is applied to one spring Because of concentration, deflection may occur in the spring sheet 102 provided on the side where the load is concentrated.

그러나, 이 스프링시이트(102)는 조립시 쇽업소버몸체(101)에 용접시키게 되므로, 보수작업이 용이하지 못하여 차체가 한쪽으로 기울어지는 경우 이를 바로잡아 주기가 매우 불편하여 주행시 승차감을 저하시키게 될 뿐 아니라, 조정 안정성에도 영향을 미치게 되어 안전운행에 해를 끼치게 된다는 문제가 있었다.However, since the spring sheet 102 is welded to the shock absorber body 101 during assembly, it is not easy to repair and thus it is very inconvenient to correct it when the vehicle body is inclined to one side, thereby lowering the riding comfort during driving. In addition, there is a problem that it will affect the stability of the adjustment and harm the safe operation.

이에 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로, 쇽업소버의 외주면에 형성된 랙크에 너클브라켓트에 설치된 피니언을 치차결합시켜 피니언과 랙크를 매개로 쇽업소버의 설치높이를 조절하여 차량 자세를 수평으로 유지할 수 있도록 된 차량의 차고 조정장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, by coupling the pinion installed on the knuckle bracket gear to the rack formed on the outer circumferential surface of the shock absorber to adjust the installation height of the shock absorber through the pinion and the rack. It is an object of the present invention to provide a vehicle height adjustment device capable of maintaining a horizontal position.

상기한 바의 목적을 달성하기 위한 본 발명은, 쇽업소버몸체의 외주면에 랙크가 형성되고, 상기 쇽업소버에 결합된 너클브라켓트에 피니언이 설치브라켓트를 매개로하여 설치되어, 상기 랙크와 치차결합됨에 따라, 상기 쇽업소버몸체를 상하로 이동시켜 쇽업소버의 설치높이를 재셋팅할 수 있도록 구성되어 간단한 방법으로 차량높이를 가변시킬 수 있도록 되어 있다.The present invention for achieving the above object, the rack is formed on the outer circumferential surface of the shock absorber body, the pinion is installed on the knuckle bracket coupled to the shock absorber via the mounting bracket, and the gear is coupled to the rack Accordingly, the shock absorber body is configured to reset the installation height of the shock absorber by moving the shock absorber body up and down so that the vehicle height can be changed in a simple manner.

이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 따른 쇽업소버의 개략적인 단면도이고, 제2도는 제1도에서 너클브라켓트만을 나타낸 사시도로서, 쇽업소버몸체(1) 외주면하단에 랙크(2)가 형성되고, 상기 쇽업소버몸체(1)에 결합된 너클브라켓트(3)에 피니언(4)이 설치브라켓트(5)를 매개로하여 설치되어, 상기 랙크(2)와 치차결합된 상태에서 피니언(4)을 회전시킴으로써 쇽업소버몸체(1)에 형성된 랙크(2)가 상하운동되어 쇽업소버(6)의 설치위치를 상하로 조정할 수 있도록 되어 있다.FIG. 1 is a schematic cross-sectional view of the shock absorber according to the present invention, and FIG. 2 is a perspective view showing only the knuckle bracket in FIG. 1, wherein the rack 2 is formed at the lower circumferential surface of the shock absorber body 1, and the shock absorber body is shown. A pinion (4) is installed on the knuckle bracket (3) coupled to (1) via the mounting bracket (5), and the shock absorber body is rotated by rotating the pinion (4) in a state of gear engagement with the rack (2). The rack 2 formed in (1) is moved up and down so that the installation position of the shock absorber 6 can be adjusted up and down.

그리고, 상기 피니언(4)의 회전축(7)일단에는 소정형상의 요홈부(7a)가 형성되어, 이 요홈부(7a) 형상에 대응되는 랜치(wrench)를 결합시켜 이 렌치를 회전시킴에 따라 회전될 수 있도록 되어 있다.In addition, at one end of the rotation shaft 7 of the pinion 4, a recessed portion 7a of a predetermined shape is formed, and a wrench corresponding to the recessed portion 7a shape is engaged to rotate the wrench. It can be rotated.

한편, 상기 너클브라켓트몸체(8)에 형성된 고정구멍(9)을 매개로 보울트(10)와 같은 부재를 조여줌으로써 쇽업소버몸체(1)가 너클브라켓트몸체(8)에 조립된 상태를 유지할 수 있도록 되어 있어, 차량 주행에 따른 충격이나 기타 외적인 요인으로 인하여 쇽업소버몸체(1)가 회전되는 것이 방지하도록 되어 있다.Meanwhile, by tightening a member such as the bolt 10 through the fixing hole 9 formed in the knuckle bracket body 8, the shock absorber body 1 can be maintained assembled to the knuckle bracket body 8. Therefore, the shock absorber body 1 is prevented from rotating due to an impact or other external factors caused by the vehicle driving.

이에 따라 상기 쇽업소버몸체(1)와 이에 일체로 형성된 랙크(2)가 수직높이가 일정한 피니언(4)의 회전에 의해 상하운동되어 쇽업소버(6)의 설치위치를 가변시킬 수 있게 됨에 따라, 상기한 바와 같이 차체가 어느 한쪽 방향으로 기울어 차량자세가 불량해져 있는 경우에 이를 용이하게 재셋팅할 수 있어, 종래와 같이 스프링 전체를 교환한다든가 스프링시이트(2)를 다시 고정시켜야 하는 작업을 할 필요가 없게 된다.Accordingly, the shock absorber body 1 and the rack 2 formed integrally therewith are vertically moved by the rotation of the pinion 4 having a vertical height, thereby changing the installation position of the shock absorber 6, As described above, when the vehicle body is inclined in either direction and the vehicle posture is poor, the vehicle body can be easily reset, so that the work of replacing the entire spring or fixing the spring sheet 2 again as in the prior art can be performed. There is no need.

이상 설명한 바와 같이 본 발명에 따른 차량의 차고 조정장치에 의하면, 쇽업소버의 외주면에 랙크를 형성하고 이와 치차결합되는 피니언을 너클브라켓트에 설치시켜 줌으로써 랙크와 피니언을 매개로 쇽업소버의 설치높이를 조절하여 차량 자세를 수평으로 유지할 수 있도록 되어 차량자세를 용이하게 재셋팅할 수 있는 효과가 있다.As described above, according to the vehicle height adjusting apparatus of the present invention, by forming a rack on the outer circumferential surface of the shock absorber and installing the pinion coupled to the knuckle bracket, the height of the shock absorber is adjusted through the rack and the pinion. The vehicle posture can be maintained horizontally so that the vehicle posture can be easily reset.
