The invention discloses a hydro-pneumatic suspension system which comprises an energy accumulator unit and an oil cylinder unit, wherein the energy accumulator unit comprises a first energy accumulator and a second energy accumulator which are connected together in parallel, and the relationship among the preset pressure P1 of the first energy accumulator, the preset pressure P2 of the second energy accumulator, the system pressure P < empty > when the vehicle is in a no-load state and the system pressure P < full > when the vehicle is in a full-load state is as follows: P1 < P < empty > < P2< P < full >; the oil cylinder unit comprises an oil cylinder, the oil cylinder comprises a rodless cavity and a rod cavity, the rodless cavity is communicated with the rod cavity, the rodless cavityis communicated with the first energy accumulator and the second energy accumulator, one end of the oil cylinder is connected with a vehicle axle, and the other end of the oil cylinder is connected with a vehicle frame. The invention further provides a vehicle with the hydro-pneumatic suspension system. The hydro-pneumatic suspension system provided by the invention only comprises two main components, namely the energy accumulator and the oil cylinder, is simple in structure, easy to maintain and low in price, and can provide better damping performance under different working conditions of empty and full loads.

    本发明公开了一种油气悬架系统,包括蓄能器单元和油缸单元,其中,蓄能器单元包括并联在一起的第一蓄能器和第二蓄能器,第一蓄能器的预设压力P1、第二蓄能器的预设压力P2、车辆空载时的系统压力P空以及车辆满载时的系统压力P满之间的关系为:P1<P空<P2<P满;油缸单元包括油缸,油缸包括无杆腔和有杆腔,无杆腔与有杆腔连通,无杆腔与第一蓄能器以及第二蓄能器连通,油缸的一端与车轴连接,油缸的另一端与车架连接。本发明还提供了一种具有上述油气悬架系统的车辆。本发明提供的油气悬架系统仅有蓄能器和油缸两种主要元器件,其系统结构简单、易于维护、价格便宜,并且在空满载不同工况下均能提供较好的减震性能。
