The invention discloses an energy accumulator, a manufacturing method of the energy accumulator, a hydraulic suspension system and a vehicle, according to the scheme of the invention, oil liquid is filled firstly, then air is filled, the inner pressure and the outer pressure of the pipe wall of a metal corrugated pipe are balanced in the process of filling high-pressure air by utilizing the incompressibility of the oil liquid, and the probability that the pipe wall of the metal corrugated pipe is expanded to be broken is reduced. In addition, compared with a non-metal leather bag, the metal corrugated pipe which is sealed and welded after inflation is used, the corrosion resistance and the high and low temperature resistance of the energy accumulator are improved, inflation maintenance is omitted, and the service life is prolonged.
本发明公开了一种蓄能器及其制造方法、液压悬架系统和车辆,本申请的方案先充油液再充气,利用油液的不可压缩性,在充入高压气体的过程中使得金属波纹管的管壁的内外压得以平衡,降低了金属波纹管的管壁涨破的概率。另外,相较于非金属皮囊,本申请使用充气后封焊的金属波纹管,提高了蓄能器的耐腐蚀、耐高低温性能,免去充气维护,延长了使用寿命。
