The active oil-gas hybrid suspension mechanism comprises a hydraulic cylinder, a piston, a piston rod, an energy accumulator, a spiral pipe and a control valve system, the piston is transversely arranged in the hydraulic cylinder and divides the hydraulic cylinder into an upper cavity and a lower cavity, and the piston rod extends out of the lower cavity of the hydraulic cylinder after being perpendicularly connected with the piston; an upper oil port formed in one end of the upper cavity is communicated with an energy accumulator, the other end of the energy accumulator is communicated with a spiral pipe, the other end of the spiral pipe is communicated with a lower oil port of the lower cavity through a control valve system, and damping holes and/or one-way valves are arranged at the two ends of the piston. The defect that dynamic adjustment of the inerter cannot be achieved by packaging a flywheel or an inerter with mass inertia is overcome, the damping of a traditional hydro-pneumatic suspension can only be changed by actively adjusting the flow of a damping hole, dynamic adjustment and control of the damping and the inerter are achieved at the same time, and therefore the vibration reduction effect of the hydro-pneumatic suspension is improved.
本发明公开了一种基于惯容器的主动油气混合悬架机构,包括液压缸、活塞、活塞杆、蓄能器、螺旋管和控制阀系统,所述活塞横置在所述液压缸内将其分为上下两个腔体,所述活塞杆与所述活塞垂直相连后从液压缸的下腔伸出,上腔的一端设有的上油口与蓄能器连通,所述蓄能器的另一端与螺旋管连通,所述螺旋管的另一端通过控制阀系统与下腔的下油口连通,在所述活塞的两端具有阻尼孔和/或单向阀,克服了封装飞轮或者质量惯性的惯容器不能实现动态调节惯容的缺点,以及传统油气悬架只能通过主动调节阻尼孔流量的方式改变油气悬架阻尼,同时实现阻尼和惯容的动态调节与控制,从而提高油气悬架的减振效果。
