The invention relates to a hydro-pneumatic spring, and belongs to the technical field of automobile chassis suspensions, the hydro-pneumatic spring comprises a cylinder body assembly, a hydraulic piston assembly and a gas piston assembly, the cylinder body assembly comprises an upper connecting support and a cylinder body, the upper part of the cylinder body is mounted in the connecting support and is locked by a fastening assembly, and the upper connecting support is provided with a hydraulic channel communicated with the interior of the cylinder body; the hydraulic piston assembly comprises a lower connecting support of an integrated structure and a hollow piston rod, the upper portion of the piston rod is located in the cylinder body, and a piston sleeve is arranged between the top end of the piston rod and the inner wall of the cylinder body; a hydraulic guide pipe is fixedly arranged at the upper end of the gas spring piston and penetrates through the piston ring. And the working pressure of gas is reduced, and the rigidity and damping of the hydro-pneumatic spring can be adjusted in real time by a vehicle-mounted air pressure system on the premise that the performance requirement and the response speed of the wheel are guaranteed, so that the method is an active suspension core technology.

    本发明涉及一种油气弹簧,属于汽车底盘悬架技术领域,包括缸体组件、液压活塞组件及气体活塞组件,缸体组件包括上连接支座和缸体,缸体上部安装在连接支座内并使用紧固组件锁紧,上连接支座上开设有与缸体内部连通的液压通道,液压活塞组件包括一体式结构的下连接支座和内部中空的活塞杆,活塞杆上部位于缸体内,活塞杆顶端与缸体内壁之间设有活塞套,气体活塞组件包括活塞杆内部活动设置的气体弹簧活塞以及固定设置的液压隔环,气体弹簧活塞上端固定设有液压导管,液压导管贯穿活塞环。降低了气体的工作压力,保证车轮性能要求和响应速度的前提下,实现了车载气压系统可以实时调节油气弹簧的刚度和阻尼,为一种主动悬架核心技术。
