多轴重型车辆的油气悬架系统及其优化设计方法
摘要：
本发明涉及一种多轴重型车辆的油气悬架系统及其优化设计方法，油气悬架系统包括设置在各车桥两端的油气悬架，油气悬架包括上横臂、下横臂和油气弹簧，上横臂和下横臂的里端与车架铰接，上横臂和下横臂的外端与轮组铰接，油气弹簧的下端与上横臂铰接，油气弹簧的上端与车架铰接；多个车桥分为前桥组和后桥组，前桥组左侧的油气弹簧相互连通，前桥组右侧的油气弹簧相互连通，后桥组左侧的油气弹簧相互连通，后桥组右侧的油气弹簧相互连通，其具体结构简单、性能稳定、减振性能好、抗侧倾能力强的优点，提高了车辆在复杂路路行驶时的平顺性。油气悬架系统的优化设计方法具有流程简单、实现容易的优点。
摘要（英）：

The invention relates to an oil-gas suspension system of a multi-axle heavy vehicle and an optimized design method of the oil-gas suspension system. The oil-gas suspension system includes pieces of oil-gas suspension arranged at the two ends of all axles, each oil-gas suspension includes an upper transverse arm, a lower transverse arm and an oil-gas spring, the inner ends of the upper transverse arms and the lower transverse arms are hinged to a vehicle frame, the outer ends of the upper transverse arms and the lower transverse arms are hinged to wheel sets, the lower ends of the oil-gas springs are hinged to the upper transverse arms, and the upper ends of the oil-gas springs are hinged to the vehicle frame; and the multiple axles are divided into a front axle set and a rear axle set, theoil-gas springs on the left side of the front axle set communicate with each other, the oil-gas springs on the right side of the front axle set communicate with each other, the oil-gas springs on theleft side of the rear axle set communicate with each other, and the oil-gas springs on the right side of the rear axle set communicate with each other. The oil-gas suspension system has the advantages of simple specific structure, stable performance, good vibration reduction performance and high anti-roll ability, and the riding comfort when the vehicle travels on a complex road is improved. Theoptimized design method of the oil-gas suspension system has the advantages of simple process and easy realization.
