An energy accumulator suspension oil cylinder comprises a cylinder barrel and two piston rod mechanisms, the two piston rod mechanisms are arranged at the upper end and the lower end of the cylinder barrel respectively in a sliding mode, and a first oil cavity is formed between the two piston rod mechanisms, wherein at least one piston rod mechanism is a piston rod mechanism provided with a gas energy storage part. The invention further provides an oil-gas balance suspension system comprising the energy accumulator suspension oil cylinder and a vehicle. The oil-gas balance suspension system comprises two energy accumulator suspension oil cylinders and an oil pipe, and first oil cavities in the two energy accumulator suspension oil cylinders are communicated through the oil pipe. According to the oil-gas balance suspension system and the vehicle adopting the energy accumulator suspension oil cylinder, overload of a single axle can be effectively avoided, the smoothness and comfort of the vehicle in the no-load state and the full-load state can be met at the same time, the design requirement for light weight and compactness is met, and a larger installation space is provided for other components; and the whole machine assembly quality is reduced, and the vehicle loading capacity is improved.

    一种蓄能器悬挂油缸,包括缸筒及两个活塞杆机构,两个所述活塞杆机构分别滑动地设于所述缸筒的上、下两端,并在两个所述活塞杆机构之间形成第一油腔;其中,至少一所述活塞杆机构为设有气体储能部的活塞杆机构。本发明还提供一种包括所述蓄能器悬挂油缸的油气平衡悬架系统及车辆。所述油气平衡悬架系统包括两个蓄能器悬挂油缸及油管,两个所述蓄能器悬挂油缸中的第一油腔通过油管连通。采用所述蓄能器悬挂油缸的油气平衡悬架系统及车辆,可以有效避免单桥超载,还可同时满足车辆在空载和满载时平顺性和舒适性,且符合轻量化紧凑化设计要求,为其他元器件提供更大的安装空间;降低了整机装配质量,提高了车辆装载能力。
