The invention discloses a hydro-pneumatic suspension module which comprises a lifting control valve unit, a first adjusting valve unit, a second adjusting valve unit, a left suspension oil cylinder unit, a right suspension oil cylinder unit, a first energy storage unit and a second energy storage unit; the lifting control valve unit is arranged on an oil supply and return path of the hydro-pneumatic suspension module, and the two energy storage units are arranged on working oil paths of the left and right suspension oil cylinder units; the first adjusting valve unit and the second adjusting valve unit are arranged between the lifting control valve unit, the left suspension oil cylinder unit and the right suspension oil cylinder unit so as to control on-off of an oil way where the first adjusting valve unit and the second adjusting valve unit are located and the through-flow flow rate and switch the oil supply modes of the suspension oil cylinder units; each of the left suspension oil cylinder unit and the right suspension oil cylinder unit comprises at least one suspension oil cylinder. The hydro-pneumatic suspension module has multi-stage rigidity adapting to various working states. The invention further discloses a hydro-pneumatic suspension system and a vehicle, wherein the suspension rigidity is adjustable, and the driving comfort level is high.
