Description

이륜차 및 자동차 유압 완충기의 감쇠력 조절장치 {Decrease the shock of shockabsorber}Damping force control device for motorcycle and automobile hydraulic shock absorber {Decrease the shock of shockabsorber}

본 발명은 이륜 및 자동차 주행시 발생하는 노면과의 충격을 감소시키는 유압완충기에 관한 것으로 운전자가 자동차의 승차감을 조절해 운전 중 피로를 감소시켜 안전성을 향상하는데 목적이 있다.The present invention relates to a hydraulic shock absorber for reducing the impact of the two-wheel and the road surface generated when driving the vehicle is aimed to improve safety by reducing the fatigue during driving by the driver to adjust the riding comfort of the car.

이륜차 및 자동차 유압 완충기는 감쇠력을 조절하는 피스톤이 실린더 안에서 작동하고 실린더는 고압을 견뎌내야 하기 때문에 단단히 밀폐돼 있다. 운전자가 완충기의 감쇠력을 조절하려면 피스톤을 열고 닫는 디스크 밸브를 수정해야 가능하기 때문에 쉽지 않았다. 자동차에는 솔레노이드를 이용하거나 피스톤 또는 실린더를 변형하여 감쇠력을 조절하려는 시도는 많았으나 설치공간의 제약과 외관이 직접노출되는 이륜차에서는 적용이 어려웠다.Motorcycles and automotive hydraulic shock absorbers are tightly sealed because the pistons that control the damping force operate inside the cylinder and the cylinder must withstand high pressure. It was not easy because the operator could modify the piston valve to open and close the piston to adjust the damping force of the shock absorber. In automobiles, many attempts have been made to control damping forces by using solenoids or by modifying pistons or cylinders.

이륜차 및 자동차의 승차감을 운전자가 노면상태와 자신의 감각에 맞도록 감쇠력을 조절해 편안한 운전과 안전을 향상하는데 목적이 있다.Its purpose is to improve comfortable driving and safety by adjusting the damping force to fit the driver's road condition and his / her sense of riding comfort.

피스톤 로드(9)에 구멍을 뚫고 그 안쪽에 유량 조절봉(10)을 삽입하여 오리피스(8)를 개폐할 수 있도록 한다.Drill a hole in the piston rod (9) to insert the flow control rod 10 therein to open and close the orifice (8).

자동차 운전자가 장시간 운전에서 느끼는 피로감을 줄임으로써 운전에 대한 집중성을 높여 안전성을 향상시키고 사고를 줄이는 효과가 있으며, 차에 대한 애착심을 고취시켜 제품수명도 연장시킬 수 있다.By reducing the fatigue that a car driver feels in driving for a long time, the driver can concentrate on driving to improve safety and reduce accidents, and can increase the life of the product by inspiring attachment to the car.

첨부된 도면을 참조하여 상세히 설명을 하면 다음과 같다.When described in detail with reference to the accompanying drawings as follows.

제1도는 유압 완충기 내부를 설명한 것으로, 피스톤(4)은 실린더를(1) 하중과 충격에 의해 상하왕복 운동하게 된다. 피스톤(4)은 스톱퍼(6)와 밸브 세트(3, 5)가 조합되어 너트(2)로 피스톤 로드(9)와 결합돼 있다. 완충기 외부에서 힘이 가해지면 1차적으로 스프링(13)이 충격을 흡수하며 피스톤(4)에 힘을 전달하고, 피스톤(4)은 디스크 밸브(3, 5)가 피스톤(4) 내부의 오리피스를 통과하려는 유압오일에 적당한 저항을 발생시켜 스프링(13)의 탄성력을 감쇄하여 준다. 이러한 구조는 현재 가장 많이 사용하고 있는 일반적은 형태의 피스톤 구조다. 1 illustrates the inside of the hydraulic shock absorber, and the piston 4 moves up and down the cylinder by the load and the impact. The piston 4 is combined with the piston rod 9 by a nut 2 by the combination of the stopper 6 and the valve sets 3 and 5. When a force is applied outside the shock absorber, the spring 13 first absorbs the shock and transmits force to the piston 4, which causes the disc valves 3 and 5 to orifice inside the piston 4. Produces a proper resistance to the hydraulic oil to pass through to reduce the elastic force of the spring (13). This structure is the most common type of piston structure currently in use.

이런 구조의 유압 완충기는 차체와 운전자의 무게로 인해 실린더 내부는 일정 이상의 압력이 형성되고 이 압력은 평형을 유지하기 위해 피스톤(4)을 밀게 된다. 피스톤(4)은 압력의 힘에 비례하여 디스크 밸브(5)가 열려 유압오일을 뒤쪽으로 보내게 되고, 압축 스프링(13)의 반발력과 실린더 디스크 밸브(5)의 저항력이 내부압력과 평형이 될 때까지 오일이 흐르게 된다.Due to the weight of the body and the driver, the hydraulic shock absorber of this structure creates a certain pressure inside the cylinder, and this pressure pushes the piston 4 to maintain an equilibrium. The piston 4 opens the disc valve 5 in proportion to the force of the pressure to send the hydraulic oil to the rear, and the repulsive force of the compression spring 13 and the resistance of the cylinder disc valve 5 are in equilibrium with the internal pressure. Oil will flow until

이때 디스크 밸브(5)를 열 정도가 아닌 작은 힘이 노면에서 전달된다면 이는 운전자에게 그대로 전달되며 완충기는 그 역할을 하지 못하게 된다.At this time, if a small force is transmitted from the road surface rather than opening the disc valve 5, it is transmitted as it is to the driver and the shock absorber does not play its role.

본 발명은 이점을 개선한 것으로, 피스톤 로드(9)에 구멍을 뚫고 그 속으로 유량을 제어할 끝 부위를 뾰족하게 가공한 유량 조절봉(10)을 삽입해 오리피스(8)를 통과하는 유압오일을 미세하게 제어 가능하도록 했다. 가이드(7)와 캡(14)을 조립하고 피스톤 로드(9) 끝 부분에 오일이 새지 않도록 오 링(11)과 부시(12)를 삽입 후 브래킷(18)을 조립한다. 브래킷(18)에는 유량 조절봉(10)을 조종할 수 있는 스크루볼트(19)와 사용자가 조정할 레버(20)를 결합한다.The present invention improves the advantages, the hydraulic oil passing through the orifice (8) by inserting a flow control rod (10) with a pointed end of the hole to control the flow rate into the piston rod (9) The fine control was made possible. Assemble the guide (7) and cap (14), insert the o-ring (11) and bush (12) so that oil does not leak to the end of the piston rod (9), and then assemble the bracket (18). The bracket 18 combines a screw bolt 19 that can operate the flow adjusting rod 10 and a lever 20 to be adjusted by the user.

피스톤 로드(9)는 피스톤(4) 앞뒤로 관통됐기에 디스크 밸브가 열리지 않는 작은 힘에도 유압오일을 흐르게 하여 완충작용을 할 수 있으며 강한 충격에 있어서도 한결 부드러운 작동이 가능하다. The piston rod 9 penetrates the piston 4 back and forth to allow the hydraulic oil to flow even with a small force that does not open the disc valve, thereby providing a cushioning function and smooth operation even in a strong impact.

유량 조절봉(9)의 열림은 실린더(1) 내부에서 발생한 압력으로 자연스럽게 후진하며 유압오일 리턴 시는 후미 쪽의 오 링(10)이 봉(9)을 강하게 지지하기 때문에 레버(20)를 돌려 닫아 주기 전에는 전진하지 않는다.The opening of the flow regulating rod 9 is naturally reversed by the pressure generated inside the cylinder 1, and when the hydraulic oil is returned, the lever 20 is rotated because the rear o-ring 10 strongly supports the rod 9. Do not advance until you close it.

이 구조는 간단하고 미세한 조절이 가능하며 고장가능성이 거의 없다.This structure is simple, finely tuned and very unlikely to fail.
