The invention relates to a hydro-pneumatic suspension system design method of an 8 * 8 heavy high motor vehicle, and solves the problem that the heights of a left suspension and a right suspension are inconsistent under the condition of unbalance loading of the whole vehicle. The system adopts a structural form of a double-wishbone independent suspension and a hydro-pneumatic spring, double wishbones are of an unequal-length structure, and the outer ends of the wishbones are connected with hub reducers; the first axle and the second axle adopt the same suspension module, namely a front suspension module, the third axle and the fourth axle adopt the same suspension module, namely a rear suspension module, and the oil gas suspension system comprises the front suspension module, a hydraulic oil tank, the rear suspension module, an angle sensor, an oil cylinder, a pipeline, a main valve and a gear pump. The whole vehicle hydro-pneumatic springs are divided into six groups by the system, and main oil cavities and annular cavities of the hydro-pneumatic springs on the left side and the right side of the same axle are crossed and interconnected to form high-stability interconnected balanced suspension. The high-maneuverability off-road performance requirement of the 8 * 8 heavy truck, the anti-roll capacity requirement under the unbalance loading use working condition and the function use requirement of lifting the truck posture can be met.

    本发明涉及一种8×8重型高机动车的油气悬架系统设计方法,解决了整车偏载情况下左右悬架高度不一致的问题。系统采用“双横臂独立悬架+油气弹簧”的结构型式,双横臂为不等长结构,横臂外端连接轮边减速器;一、二桥采用相同的悬架模块即前悬架模块,三、四桥采用相同的悬架模块即后悬架模块,油气悬架系统包括前悬架模块、液压油箱、后悬架模块、角度传感器、油缸、管路、主阀和齿轮泵。系统将整车油气弹簧分成六组,对同桥左右侧油气弹簧的主油腔和环形腔进行交叉互联,形成高稳定性互联式平衡悬挂。本发明可以满足8×8重型卡车高机动越野性能要求,偏载使用工况下抗侧倾能力的要求,以及升降车姿的功能使用需求。
