Zusammenfassung: | The present invention relates to a closed damper using a magneto rheological-grease (MRG) fluid, capable of providing a normal control force. According to the present invention, the closed damper using an MRG fluid comprises: a cylinder having a hollow part formed therein in a longitudinal direction; a piston rod inserted from the upper part of the cylinder; a yoke connected to the piston rod to reciprocate in the cylinder; a plurality of elastic members to provide an initial control force between the cylinder and the yoke; a sealing member installed in each groove, which is formed on both end parts of the outer circumferential surface of the yoke, to be closely attached to the inner circumferential surface of the cylinder; the MRG fluid received in an internal space between the sealing members; and a coil disposed in the yoke to allow an electromagnet to form a magnetic field upon the application of current.
본 발명은 MRG유체(Magneto-Rheological-Grease Fluid)를 이용한 전단형 댐퍼에 관한 것으로서, 내부에 길이방향으로 중공부를 가지는 실린더와 상기 실린더의 상부로부터 삽입되는 피스톤로드와 상기 피스톤로드에 연결되어 실린더의 내부에서 왕복운동 하는 요크와 상기 실린더와 요크 사이에서 초기제어력을 제공하는 복수개의 탄성부재와 상기 요크의 외주면 양 단부에 홈을 형성하고, 상기 홈에 각각 설치되어 실린더의 내주면에 밀착되도록 구비된 씰링부재와 상기 씰링부재 사이의 내부공간에 수용되는 MRG유체(Magneto-Rheological-Grease Fluid); 및 상기 요크에 구비되어 전류 공급시 전자석으로 하여금 자기장을 발생시키도록 설치된 코일을 포함한다. |
