电动轮自卸车是露天矿山物料运输的重要工程车辆。矿区复杂的道路状况对电动轮自卸车的转向系统提出了较高的要求。针对载质量220t电动轮自卸车的全液压转向系统,从分析自卸车转向负载出发,计算了全液压转向系统的主要性能参数,并以此为基础,确定了转向液压缸、转向器、流量放大器、转向液压泵和转向蓄能器的主要性能参数。并给出了全液压转向系统的总设计图及元件布置图。
電動輪自卸車是露天礦山物料運輸的重要工程車輛。礦區複雜的道路狀況對電動輪自卸車的轉嚮繫統提齣瞭較高的要求。針對載質量220t電動輪自卸車的全液壓轉嚮繫統,從分析自卸車轉嚮負載齣髮,計算瞭全液壓轉嚮繫統的主要性能參數,併以此為基礎,確定瞭轉嚮液壓缸、轉嚮器、流量放大器、轉嚮液壓泵和轉嚮蓄能器的主要性能參數。併給齣瞭全液壓轉嚮繫統的總設計圖及元件佈置圖。

Motor dump trucks are important construction vehicles in open mine.The complexity of the open mine road requires a high quality steering system for the motor dump truck.Focusing on the 220 t load motor dump truck,the steering loads of the motor dump truck were analyzed and the main parameters of the full hydraulic system were calculated.Based on these,the parameters of steering cylinder,steering unit,flow amplifier,steering pump and steering accumulator were calculated.Finally the hydraulic schemat-ics and the hydraulic component layout of the full hydraulic system were given.
