Abstract

본 발명은 요동하는 두 부재사이에 취부되어 진동 및 충격을 흡수하는 장치에 관한 것으로, 특히 실린더를 이중으로 설치하여 가진력에 따라 댐핑상수를 변화시킴으로써 가진력에 맞는 적절한 완충력을 갖도록 하여 기기를 보호하고 수명을 연장할 수 있는 이중실린더형 충격흡수장치에 관한 것이다. 본 장치는 제1실린더의 내부에 제2실린더를 삽입하여 두개의 공동으로 구획하고 이 공간상을 제2실린더가 이동케 설치한다. 그리고 제2실린더의 양단부상에 제1, 제2탄성부재를 탄설하여 압착력을 받도록 한다. 또한, 제2실린더의 내부에 피스톤을 장착하여 두개의 공동으로 분할하고 피스톤에 제2오리피스를 설치하여 이 오리피스를 통하여 유체가 유동하도록 구성했다. 아울러 제2실린더에도 제1오리피스를 형성하여 작은 충격이 미칠 경우 제2오리피스를 통하여 유체가 흐르도록 하며, 중간 정도의 힘이 작용하면 제2실린더가 이동하여 탄성부재에 의해 완충된다. 또한, 큰 힘이 작용할 경우는 제1오리피스를 통하여 유체가 흘러 가진력에 크기에 따라 댐핑상수가 변화되도록 구성했다. 이와 같이 구성함으로 기기의 수명을 연장시킬수 있으며, 가진력에 따른 적절한 완충효과를 가질 수 있다.The present invention relates to a device mounted between two swinging members to absorb vibration and shock, in particular, by installing a double cylinder to change the damping constant according to the excitation force to have a proper buffering force suitable for the excitation force to protect the device and life It relates to a double cylinder-type shock absorbing device that can extend. The apparatus inserts a second cylinder into the interior of the first cylinder and divides it into two cavities so that the second cylinder moves in this space. Then, the first and second elastic members are coalesced on both ends of the second cylinder to receive the compressive force. In addition, a piston was mounted inside the second cylinder to divide it into two cavities, and a second orifice was installed on the piston so that fluid flowed through the orifice. In addition, the first cylinder orifice is also formed in the second cylinder so that a small impact causes the fluid to flow through the second orifice. When a medium force is applied, the second cylinder moves and is buffered by the elastic member. In addition, when a large force is applied, the damping constant is changed according to the magnitude of the force of the fluid flowing through the first orifice. In this way, the life of the device can be extended, and it can have an appropriate cushioning effect according to the excitation force.
