본 발명은 승용차 차체 높이 조절장치에 관한 것이다. 통상적으로 승용차는 스트러트(a)에 코일스프링(b)을 설치하여 스프링시트(c)로 탄지되게 하여 차체에 전달되는 충격을 완충시키게 되어 있다.The present invention relates to a vehicle body height adjusting device. Typically, a passenger car is provided with a coil spring (b) on the strut (a) to be carried by the spring seat (c) to cushion the shock transmitted to the vehicle body.
이와 같은 구조로 되어 있는 승용차는 차체가 낮아 돌출 굴곡이 심한 비포장 도로를 주행시 차체의 하부구조부가 노면에 닿게 되어 손상을 입게 되고 돌출굴곡이 심한 비포장 도로를 승용차로 주행시 많은 불편을 겪게 되는 폐단이 있는 거이다.Passenger cars having such a structure are damaged due to low body, and the lower part of the body touches the road surface when driving on unpaved roads with high protruding bends, and suffers a lot of inconvenience when driving on unpaved roads with high protruding bends. That's it.
본 발명은 이러한 점을 감안하여 승용차 차체 하부에 연결되는 스트러트하단에 유압액츄에이터를 설치하여 피스톤에 의해 스프링시트를 상·하 이동되게 하므로서 노면의 굴곡사태가 심한 비포장도를 주행시 유압액츄에이터로 피스톤을 상승시켜 승용차의 차체 높이를 높여주고 일반포장도로를 주행시에는 정상높이로 승용차의 차체 높이를 낮춰서 주행할 수 있도록 하므로서 노면이 굴곡상태가 심한 비포장도로를 주행시에도 차체의 하부가 노면에 닿지 않게 하여 차체의 손상을 방지하고 운전을 편안하게 할 수 있도록 한 것으로서 첨부도면에 의거 상세히 설명하면 다음과 같다.In view of the above, the present invention installs a hydraulic actuator at the bottom of the strut connected to the lower part of the passenger car body to move the spring seat up and down by the piston, so that the piston is raised by the hydraulic actuator when driving the unpaved road with severe bend conditions. By raising the height of the car body and driving the general pavement, the vehicle height can be lowered to the normal height, so that the lower part of the body does not touch the road surface even when driving on the unpaved road. It is to prevent damage and to make driving comfortable and described in detail according to the attached drawings as follows.
승용차 바퀴에 연결되어 코일스프링(2)이 장착된 스트러트(1)의 하단에 피스톤(5)을 상승·하강시키는 유압액츄에이터(6)를 고착시켜 피스톤(5)을 코일스프링(2)을 지지하는 스프링시트(3) 저면에 고착 연결시켜서 된 것이다.A hydraulic actuator 6 is fixed to the lower end of the strut 1, which is connected to the wheel of the passenger car, on which the coil spring 2 is mounted, to thereby secure the piston 5 to support the coil spring 2. The spring seat 3 is fixedly connected to the bottom.
이와 같이 된 본 발명은 승용차가 노면의 굴곡이 심한 비포장도로를 주행할 때에는 운전자가 유압액츄에이터(6)를 제3도 b에 도시한 바와 같이 작동시키게 되면 피스톤(5)이 작동되어 피스톤(5)이 상승하면서 스프링시트(3)를 상승시키게 된다. 스프링시트(3)가 피스톤(5)에 의해 상승되면 스프링시트(3)가 상승된 만큼 차체가 들리게 된다.According to the present invention as described above, when the passenger car drives the unpaved road with severe curvature of the road, the driver operates the hydraulic actuator 6 as shown in FIG. The spring sheet 3 is raised while this rises. When the spring seat 3 is raised by the piston 5, the body is lifted as much as the spring seat 3 is raised.
이렇게 차체가 들려 차체의 높이가 높아진 상태에서 노면의 굴곡이 심한 비포장도로를 주행하게 되면 노면에 차체 하부가 닿지 않게 되어 차체 하부가 손상하지 않고 편안하게 운전을 하게 되는 것이다.When the body is lifted up and the height of the car body is raised, driving on the uneven road with severe curvature of the road will prevent the lower part of the body from reaching the road surface, and the lower part of the car body will operate comfortably without damage.
한편, 노면이 포장된 일반도로를 주행시에는 유압액츄에이터(6)를 반대로 작동시켜 피스톤(5)을 하강시키게 되면 스프링시트(3) 또한 하강되므로서 차체가 그만큼 하부로 내려오게 되어 차체의 높이는 원상태가 되게 된다.On the other hand, when driving on a road paved with road surface, if the hydraulic actuator 6 is operated in reverse, and the piston 5 is lowered, the spring seat 3 is also lowered, so that the vehicle body is lowered by that much and the height of the vehicle body is unchanged. Will be.
이와같이 본 발명은 승용차가 노면의 굴곡이 심한 비포장도로를 주행시 승용차의 차체 하부가 노면에 닿지 않게 승용차의 차체 높이를 조절할 수 있게 하므로서 노면의 굴곡이 심한 비포장도로에서는 차체 높이를 높여 차체 하부가 노면에 닿지 않도록 하여 차체 하부손상을 방지하고 편안한 운전을 할 수 있게 하며, 일반포장도로에서는 차체 높이를 정상상태로 조절하여 주행할 수 있도록 한 것이다.As described above, the present invention enables the vehicle body to adjust the height of the car so that the lower part of the car does not touch the road surface when the passenger car is driving on the unpaved road with severe curvature of the road. It prevents damage to the lower part of the body and allows comfortable driving, and it is possible to drive by adjusting the height of the body to the normal state on the pavement.
