본 발명은 승용차 차체 높이 조절장치에 관한 것이다.The present invention relates to a vehicle body height adjusting device.

통상적으로 승용차는 차체가 낮아 돌출 굴곡이 심한 비포장도로를 주행시 차체의 하부구조부가 노면에 닿게되어 손상을 입게되고 돌출굴곡이 심한 비포장도로를 승용차로 주행시 많은 불편을 겪게 되는 폐단이 있는 것이다.In general, when a passenger car runs on an unpaved road with low protruding curves, the undercarriage of the car body is damaged by contact with the road surface, and there is a discomfort when driving a non-paved road with severe protrusion bends.

본 발명은 이러한 점을 감안하여 승용차 차체 하부에 연결되는 쇼크압소바 상단에 유압실린더로 회동되어 승용차 차체 높이를 조절하게 되는 회동구를 장착하므로서 노면의 굴곡상태가 심한 비포장도로를 주행시 유압실린더로 회동구를 회동시켜 승용차 차체 높이를 높여주고 일반포장도로를 주행시에는 정상높이로 승용차 차체 높이를 낮춰서 주행할 수 있도록 하므로서 노면의 굴곡상태가 심한 비포장도로를 주행시에도 차체의 하부가 노면에 닿지않게 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 is equipped with a rotational port which is rotated by a hydraulic cylinder on the top of a shock pressure soba connected to the lower part of a passenger car body to adjust the height of the passenger car body, and is driven by a hydraulic cylinder when driving on an unpaved road with a severe curved surface. By raising the height of the passenger 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 where the road is severely curved. 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 쇼크압소바(1) 상단에 굴곡형성된 회동구(3)의 일측단을 힌지(4)로 연결하고 타측단은 차체(8)에 고정된 유압실린더(6)의 실린더축(7)에 힌지(4')로 연결하며, 중간부는 차체(8)에 고착된 고정구(5)에 힌지(4')로 연결시켜서 된 것이다.A hydraulic cylinder fixed to the vehicle body 8 by connecting one end of the bend-shaped turning hole 3 connected to the wheel of the passenger car and having the coil spring 2 mounted thereon to a hinge 4. It connects to the cylinder shaft 7 of (6) by the hinge 4 ', and the intermediate part is connected by the hinge 4' to the fixture 5 fixed to the vehicle body 8.

이와 같이 된 본 발명은 승용차가 노면의 굴곡이 심한 비포장도로를 주행할 때에는 운전자가 유압실린더(6)를 제2도에 도시한 바와 같이 작동시키게 되면 실린더(6)가 작동되어 실린더(6)의 실린더축(7)이 힌지(4')로 연결된 회동구(3)를 당기게 된다. 실린더축(7)이 회동구(3)를 당기게 되면 회동구(3)는 차체(8)에 고정된 고정구(5)에 힌지(4'')로 연결되어 있어 힌지(4'')를 중심으로 회동되면서 차체(8)가 들리게 된다.According to the present invention as described above, when the passenger car drives the hydraulic cylinder 6 as shown in FIG. 2 when driving on the uneven road with severe curvature of the road surface, the cylinder 6 is operated to operate the cylinder 6. The cylinder shaft 7 pulls the pivoting hole 3 connected by the hinge 4 '. When the cylinder shaft 7 pulls the pivoting hole 3, the pivoting hole 3 is connected to the fixture 5 fixed to the vehicle body 8 by a hinge 4 '' so that the center of the hinge 4 '' is centered. As the body rotates, the body 8 is heard.

이렇게 차체(8)가 들려 차체의 높아진 상태에서 노면의 굴곡이 심한 비포장도로를 주행하게 되면 노면에 차체(8)의 하부가 닿지 않게 되어 차체(8)의 하부가 손상되지 않고 편안하게 운전을 하게 되는 것이다.When the body 8 is lifted up and the vehicle body is raised, driving on a dirt road with severe curvature of the road surface prevents the lower portion of the vehicle body 8 from touching the road surface, thus allowing the lower portion of the vehicle body 8 to be operated comfortably without being damaged. Will be.

한편, 노면이 포장된 일반도로를 주행시에는 실린더(6)를 반대로 작동시켜 실린더축(7)을 밀어주면 실린더축(7)에 힌지(4')로 연결된 회동구(3)가 회동되므로서 실린더축(7)이 회동구(3)를 하부로 밀어준 높이 만큼 회동구(3)가 힌지(4")를 중심으로 회동되면서 회동구(3)의 중간에 고정구(5)로 연결된 차체(8)가 하부로 내려오게 되어 차체(8)의 높이는 원상태가 되게 된다.On the other hand, when driving on a road paved with a road surface, the cylinder 6 is operated reversely to push the cylinder shaft 7 so that the pivoting hole 3 connected to the cylinder shaft 7 by the hinge 4 'is rotated. The body 8 connected by the fastener 5 in the middle of the pivot 3 while the pivot 3 is rotated about the hinge 4 "by the height that the shaft 7 pushes the pivot 3 downward. ) Is lowered to the bottom, the height of the vehicle body 8 is in the original state.

상기와 같이 구성된 본 발명은 제4도에 도시한 바와같이 회동구(3)의 일측을 랙기어(9)로 형성하여 차체(8)에 고정되어 모터(10)로 회전되는 워엄기어(11)에 이맞물림시켜 구성할 수도 있다.According to the present invention configured as described above, as shown in FIG. It can also be configured to mesh with.

이렇게 회동구(3)의 일측을 랙기어(9)에 형성하고 모터(10)로 회전되는워엄기어(11)에 이맞물림시켜 구성된 것은 노면의 굴곡이 심한 비포장도로를 주행시 모터(10)를 작동시켜 워엄기어(11)를 회전시키면 워엄기어(11)에 이맞물림된 랙기어(9)가 워엄기어(11)를 타고 상부로 올라가게 되어 고정구(5)가 힌지(4")로 연결된 부분이 상승되므로 차체(8)의 높이가 높아지게 되어 노면의 굴곡이 심한 비포장도로를 차체(8) 하부가 노면에 닿지 않고 주행할 수 있게 되며, 노면이 포장된 일반도로를 주행시에는 모터(10)를 역회전시켜 워엄기어(11)를 역회전 시키면 랙기어(9)가 워엄기어(11)를 타고 내려오게 되면서 회동구(3)와 고정구(5)가 힌지(4")로 연결된 부분이 하강하게 되어 차체(8)의 높이가 정성높이로 되어 포장 도로를 정상상태로 주행하게 되는 것이다.One side of the turning hole 3 is formed on the rack gear 9 and engaged with the worm gear 11 that is rotated by the motor 10 to operate the motor 10 when driving on an unpaved road with severe curvature of the road surface. When the worm gear 11 is rotated, the rack gear 9 meshed with the worm gear 11 is lifted upward by the worm gear 11 so that the part 5 is connected to the hinge 4 ". Since the height of the vehicle body 8 is increased, the vehicle 8 can be driven on the unpaved road where the curvature of the road surface is severe, and the lower part of the vehicle body 8 does not touch the road surface. Rotating the worm gear 11 by rotating the rack gear 9 descends while riding the worm gear 11 so that the pivoting hole 3 and the fixture 5 connected by the hinge 4 "are lowered. The height of the vehicle body 8 becomes the qualitative height, so that the pavement road is driven in the normal state.

이와같이 본 발명은 승용차가 노면의 굴곡이 심한 비포장도로를 주행시 승용차의 차체(8) 하부가 노면에 닿지 않게 승용차의 차체(8)높이를 조절할 수 있게 하므로서 노면의 굴곡이 심한 비포장도로에서는 차체(8)높이를 높여 차체(8)하부가 노면에 닿지 않도록하여 차체(8) 하부손상을 방지하고 편안한 운전을 할 수 있게 하며, 일반포장도로에서는 차체(8) 높이를 정상상태로 조절하여 주행할 수 있도록 한 것이다.As described above, the present invention allows the vehicle body 8 of the passenger car to be adjusted so that the lower part of the vehicle body 8 of the passenger car does not touch the road surface when the passenger car runs on the unpaved road where the road surface is severely curved. By raising the height, the lower part of the body (8) does not touch the road surface to prevent damage to the lower part of the body (8) and comfortable driving.On the general pavement, the height of the body (8) can be adjusted to the normal state to drive. It would be.
