Description

쇽 업소버의 성능을 튜닝하기 위한 장치장치 Device for tuning the performance of the absorber

본 발명은 쇽 업소버의 감쇠력 특성을 용이하게 튜닝할 수 있도록 제작된 튜닝 장치에 관한 것으로, 쇽 업소버 내에 오일과 가스를 주입한 후 패킹 캡과 외측 튜브를 용접 결합하지 않고, 외측 튜브에 결합된 하부 지그에 대해 상부 지그를 나사 결합함에 의해서 패킹 캡과 외측 튜브가 결합되도록 하여, 쇽 업소버의 해체 및 조립이 용이하도록 하고 이에 따라 감쇠력 특성에 대한 조정작업이 용이하도록 하는 쇽 업소버의 성능을 튜닝하기 위한 장치에 관한 것이다.The present invention relates to a tuning device that can be easily tuned the damping force characteristics of the shock absorber, and after the oil and gas is injected into the shock absorber, the lower portion is coupled to the outer tube without welding the packing cap and the outer tube By screwing the upper jig against the jig, the packing cap and the outer tube are joined to facilitate the disassembly and assembly of the shock absorber and thus to tune the performance of the shock absorber to facilitate the adjustment of the damping force characteristics. Relates to a device.

일반적으로 쇽 업소버는 차량과 같은 진동체에 발생된 진동을 신속히 흡수하여 지속적인 잔류진동을 소멸시키기 위한 것으로서, 주로 스프링의 상부에 위치하는 바디부와 스프링의 하부에 위치하는 샤시부 사이에 설치되어져 사용된다.In general, shock absorbers are used to quickly absorb vibrations generated in a vibrating body, such as a vehicle, to extinguish continuous residual vibrations. do.

쇽 업소버는 오일이 충진된 튜브의 내부에서 선단에 피스톤 밸브가 결합된 피스톤로드가 왕복하도록 하여, 오일의 점성에 의해 차량에 발생된 진동이 감쇠되도록 하는 장치로서, 피스톤 로드가 신축운동할 시 튜브내의 오일이 피스톤 밸브를 통해 흐르면서 운동에너지가 열에너지로 변환되어지므로 차량에 발생된 진동이 감쇠되는 것이다.쇽 Absorber is a device that allows the piston rod combined with the piston valve to be reciprocated in the inside of the oil filled tube so that vibration generated in the vehicle is attenuated by the viscosity of the oil. As the oil inside flows through the piston valve, the kinetic energy is converted into thermal energy, thereby damping the vibration generated in the vehicle.

이와 같이 차량진동에 대한 감쇠작용은 대부분이 쇽 업소버의 피스톤 밸브에서 이루어 지는데, 튜브내에 충진된 오일의 점도와 가스압력등이 상기 피스톤 밸브에 의한 감쇠력 형성에 영향을 미치며 상기 피스톤 밸브의 오리피스와 디스크 매수등도 감쇠력에 결정적인 역할을 하게된다.In this way, the damping effect on the vibration of the vehicle is mostly performed in the piston valve of the shock absorber. The viscosity and gas pressure of the oil filled in the tube affect the formation of the damping force by the piston valve. Buying and the like also play a decisive role in damping force.

도 1은 종래 기술에 따른 쇽 업소버의 단면도로서 상기 도면에서 보면,1 is a cross-sectional view of a shock absorber according to the prior art, as seen from the above figure,

내부에 오일이 충진된 내측 튜브(5)와, 상기 내측 튜브(5)의 외측에 위치하는 외측 튜브(6)와, 상기 내측 튜브(5)의 내부에서 왕복운동하도록 위치하며 하단에는 피스톤 밸브(미도시함)가 결합되고 상단에는 스토퍼(31)와 수나사부(32)가 형성된 피스톤 로드(4)와, 상기 외측 튜브(6)의 상단에 결합되는 패킹 캡(4)과, 상기 패킹 캡(4)과 내측 튜브(5)의 상단 사이에 순차적으로 구비되는 씰링재(41) 및 로드 가이드(42)로 구성된다.An inner tube (5) filled with oil therein, an outer tube (6) located outside the inner tube (5), and a reciprocating motion inside the inner tube (5), and at the bottom of a piston valve ( And a piston rod 4 having a stopper 31 and a male screw portion 32 formed thereon, a packing cap 4 coupled to an upper end of the outer tube 6, and the packing cap (not shown). It consists of a sealing member 41 and a rod guide 42 which are sequentially provided between the 4) and the upper end of the inner tube (5).

그런데, 이와 같은 종래의 쇽 업소버에서는 외측 튜브(6)와 패킹 캡(4)이 용접 결합부(50)에 의한 영구적인 결합방법에 의해 결합되어지므로, 초기 조립시 튜브내의 오일 점도, 가스압력, 피스톤 밸브의 구조와 같은 제반 조건들이 일단 결정되고 나면 새로운 쇽 업소버를 다시 제작하기 전에는 상이한 조건으로 튜닝하기 어렵게 되는 문제점이 있었다.However, in the conventional shock absorber, since the outer tube 6 and the packing cap 4 are joined by a permanent bonding method by the weld joint 50, the oil viscosity, gas pressure, Once the various conditions, such as the structure of the piston valve, were determined, there was a problem that it was difficult to tune to different conditions before remanufacturing a new shock absorber.

쇽 업소버의 감쇠력 특성은 위에서 언급한 바와 같이, 튜브내의 오일 점도등과 같은 여러가지의 조건등에 의해 결정되어 지므로 차종별로 감쇠력 특성을 적합하게 설계하기 위해서는 무수한 튜닝테스트가 요구되어 지는 것이다.As mentioned above, the damping force characteristics of the absorber are determined by various conditions such as the oil viscosity in the tube. Therefore, numerous tuning tests are required to properly design the damping force characteristics for each vehicle type.

그런데, 종래에는 이와 같은 튜닝 테스트를 용이하게 실시할 수 있도록 결합 및 해체가 용이하게 제작된 쇽 업소버 튜닝 장치가 없었으므로, 쇽 업소버에 대한 효율적인 튜닝 테스트가 이루어 지지 않았으며 이에 따라 쇽 업소버의 품질향상에 어려움이 많게되는 문제점이 있었다.However, in the related art, there was no shock absorber tuning device which was easily manufactured to be combined and disassembled to easily perform such a tuning test, and thus, an efficient tuning test for the shock absorber was not performed, thereby improving the quality of the shock absorber. There was a problem with a lot of difficulty.

본 발명은 이와같은 문제점을 해결하기 위한 것으로, 쇽 업소버 내에 오일과 가스를 주입한 후 패킹 캡과 외측 튜브를 용접 결합하지 않고, 외측 튜브에 결합된 하부 지그에 대해 상부 지그를 나사 결합함에 의해서 패킹 캡과 외측 튜브가 결합되도록 하여, 쇽 업소버의 해체 및 조립이 용이하도록 하고 이에 따라 감쇠력 특성에 대한 튜닝작업이 용이하도록 하고 있다.The present invention is to solve such a problem, and after the oil and gas is injected into the shock absorber packing by screwing the upper jig against the lower jig bonded to the outer tube without welding the packing cap and the outer tube The cap and the outer tube are coupled to facilitate the disassembly and assembly of the shock absorber, thereby facilitating tuning of the damping force characteristics.

이를 위한 해결방안으로 본 발명에서는, 외측튜브의 상단에는 내측에 암나사가 형성된 하부 지그를 결합하고, 상기 하부 지그의 상부에는 상기 암나사부와 나합되도록 외주면에 수나사부가 형성된 상부 지그를 결합하되, 상기 상부지그에 의해서 패킹 캡등이 상기 내측 튜브 및 외측 튜브의 상단에 밀착 결합되도록 하고 있다.In the present invention as a solution for this, the upper end of the outer tube is coupled to the lower jig formed with a female screw on the inside, the upper jig of the upper jig to combine the upper jig formed on the outer circumferential surface to be mated with the female screw, A packing cap or the like is tightly coupled to the upper ends of the inner tube and the outer tube by the jig.
