The invention discloses a load-adaptive pressure-adjustable hydro-pneumatic suspension which comprises a load detection device, a hydraulic control structure and a middle-rear axle hydro-pneumatic suspension body. The inflation pressure of the energy accumulator of the hydro-pneumatic suspension can be actively adjusted according to the load condition of a vehicle, and the problem that the compressible stroke of the hydro-pneumatic cylinder is insufficient when the vehicle is heavy-loaded is solved. The inflation pressure of the energy accumulator can be actively adjusted, the low rigidity during light load and the high rigidity during heavy load are achieved, the damping performance of the vehicle is met, the comfort of the vehicle is improved, and the load and passing performance of the vehicle are improved.
本发明公开了一种自适应载荷的可调压油气悬架,包括载荷检测装置、液压控制结构和中后桥油气悬架主体;其能够根据车辆载重情况主动调节油气悬架的蓄能器充气压力,解决油气缸在车辆重载时的可压缩行程不足的问题;能够主动调整蓄能器充气压力,实现轻载时刚度低、重载时刚度大,既满足了车辆的减震性能,提高车辆的舒适性,又提高车辆的载重和通过性能。
