Abstract

쇽 업소버는 완충 매체로 채워지는 실린더를 포함하고, 이 실린더 안에서 피스톤을 갖춘 피스톤 로드가 피스톤과 함께 축방향을 움직이도록 형성되는데, 이때 피스톤이 실린더를 두개의 작동실로 분리하고, 상기 피스톤 로드가 완충 밸브를 포함하는데, 이 완충 밸브의 감쇠력은 솔레노이드에 의해 회수체(return body)내에 발생된 자력을 이용하여 아마추어에서 최소한 하나의 스프링의 탄성력에 부딪쳐서 변형될 수 있다. 이때 솔레노이드의 다른 흐름에 의해 서로 구별되는 최소한 두개의 특성 곡선의 조절을 위해 최소한 두개의 조절 매개변수가 존재한다. 이는 완충 밸브를 끌어올리는 위치와 연관되어 작용하는 탄성력이 변화되고 계속해서 조절 장치를 이용하여 회수체의 자력의 전도율을 조절함으로써 탄성력이 변화되기 때문이다. 상기 조정 장치는 자력을 띠는 가이드 몸체와 서로 병렬로 위치하는 자력을 띠는 좁은 틈새로 구성된다.The shock absorber comprises a cylinder filled with a buffer medium, in which a piston rod with a piston is formed to move axially with the piston, where the piston separates the cylinder into two operating chambers and the piston rod And a damping force of the buffer valve can be deformed by striking the elastic force of at least one spring in the armature using magnetic force generated in the return body by the solenoid. At least two control parameters exist for the adjustment of at least two characteristic curves distinguished from one another by different flows of solenoids. This is because the elastic force acting in association with the position where the buffer valve is pulled up is changed and the elastic force is changed by continuously adjusting the conductivity of the magnetic force of the recovery body using the adjusting device. The adjusting device is composed of a guide body with magnetic force and a narrow gap with magnetic force positioned in parallel with each other.
