The invention discloses a compact rigidity damping inerter self-control type hydro-pneumatic spring and a working method. The bottom of the lower end of a plunger of a hollow structure is sealed, is downwards connected with a wheel and extends into an oil cylinder from bottom to top, the top of the upper end of the plunger is fixedly connected with a piston, and a row of plunger holes are formed in the upper portion of the plunger; the upper part of an upper cavity of the oil cylinder is sequentially connected with a damper and a small oil-gas chamber; the lower part of a lower cavity is sequentially connected with an inerter pipe, an adjustable throttle valve and a large oil-gas chamber; the upper end of the self-control device outer cylinder is fixedly connected with the piston; a self-control device inner barrel capable of moving up and down is coaxially sleeved in the self-control device outer barrel, the lower end of the self-control device inner barrel is sealed, and the upper section of the self-control device inner barrel is hinged to the oil cylinder upper end cover; an inner barrel upper row oil through hole formed in an inner barrel of the automatic control device is always located in an upper cavity of the oil cylinder, the upper edge of an inner barrel middle row oil through hole is aligned with the upper edge of an outer barrel upper row oil through hole, and the lower edge of an inner barrel lower row oil through hole is aligned with the lower edge of an outer barrel lower row oil through hole. The rigidity is changed, and the damping and the inerter can also be changed.

    本发明公开一种紧凑型刚度阻尼惯容自控型油气弹簧及工作方法,中空结构的柱塞其下端底部密封且向下连接车轮,由下向上伸入到油缸之内且上端顶部固定连接活塞,并在上部位置开有一排柱塞孔,油缸上腔室上部依次连接阻尼器和小油气室,下腔室下部依次连接惯容管、可调节流阀和大油气室;自控装置外筒位于柱塞内,上端固定连接活塞;自控装置外筒中同轴心套有能上下移动的自控装置内筒,自控装置内筒下端密封,上段与油缸上端盖铰接;自控装置内筒上开有的内筒上排通油孔始终位于油缸的上腔室内,内筒中排通油孔的上边沿与外筒上排通油孔的上边沿对齐,内筒下排通油孔的下边沿与外筒下排通油孔的下边沿对齐;除改变刚度外,还可改变阻尼和惯容。
