The invention relates to a hydro-pneumatic suspension and a mining dump truck. The hydro-pneumatic suspension comprises a cylinder barrel, a cylinder bottom, a piston rod, a first piston, a second piston and an elastic piece, wherein the cylinder barrel is pre-filled with oil gas; the cylinder bottom is arranged at the end part of the cylinder barrel; the first end of the piston rod is movably arranged in the cylinder barrel, and the second end of the piston rod is located outside the cylinder barrel; the first piston is arranged in the cylinder barrel and connected to the first end of the piston rod; the second piston is arranged in the cylinder barrel and located between the first piston and the cylinder bottom; and the elastic piece is connected with the second piston and the cylinder bottom. According to the hydro-pneumatic suspension, double buffering and vibration reduction are achieved through the oil gas and the elastic piece, the reliability is high, and the problem that a vehicle cannot run normally under the conditions of oil gas leakage and vibration reduction failure of a hydro-pneumatic suspension with single oil gas vibration reduction is solved.

    本发明涉及一种油气悬架及矿用自卸车。其中,油气悬架包括:缸筒,其内预填充有油气;缸底,设于所述缸筒的端部;活塞杆,第一端可动地设于所述缸筒内,第二端位于所述缸筒外;第一活塞,设于所述缸筒内,且连接于所述活塞杆的第一端;第二活塞,设于所述缸筒内,且位于所述第一活塞与所述缸底之间;以及弹性件,连接所述第二活塞与所述缸底。本发明提供的油气悬架通过油气和弹性件双重缓冲减振,可靠性高,解决了单一油气减振的油气悬架在油气泄漏、减振失效的情况下,车辆无法正常行驶的问题。
