摘要摘要 大型礦用自卸車是現(xiàn)代礦山企業(yè)重要的運輸工具之一，目前普遍使用的是大型電動輪自卸車，已暴露出其體積龐大、重量大、故障率高等缺點。由于靜液壓傳動具有工作平穩(wěn)、沖擊小、重量輕、無級調(diào)速及調(diào)速范圍大、易于實現(xiàn)自動化、在惡劣工作條件下相對電傳動性能更可靠等優(yōu)點，近年來發(fā)展迅速，已受到車輛傳動領(lǐng)域的廣泛重視。在分析了礦用電動輪自卸車電動輪傳動型式、工作條件及負(fù)載變化后，參考由湘潭電機(jī)集團(tuán)有限公司生產(chǎn)的108t電動輪自卸車，結(jié)合靜液壓傳動的優(yōu)點，設(shè)計了大型礦用自卸車的靜液壓傳動系統(tǒng)，驅(qū)動是由四個液壓馬達(dá)輸出扭矩驅(qū)動車輛的四輪驅(qū)動型式，采用雙泵供油的閉式變量系統(tǒng)；鑒于轉(zhuǎn)向和舉傾不同時發(fā)生，在設(shè)計中采用舉傾時雙泵合流的供油方式，從而充分利用了發(fā)動機(jī)功率，減少了能量損耗；同時還對大型礦用自卸車的制動性能進(jìn)行了分析，能夠滿足其制動要求。關(guān)鍵詞：礦用自卸車；電動輪自卸車；靜液壓傳動AbstractThe heavy duty mineral Self-Dumping Truck is one of the important transport means in modern mine enterprise. The heavy duty Electric - Wheeled Self - Dumping Truck is widespread at present. But it has huge size, heavy weight, high failure and so on. Because the hydrostatic transmission device works steadily and is easily to realize the automation and is of small impact, light weight, large variable speed range and enabled to step-less speed and under the bad working conditions, the hydrostatic transmission device is of more reliable performance than electrical transmission device. It develops rapidly in recent years. It has been valued by more and more people in vehicle transmission. By analyzing the Electric-wheel drive forms, working conditions and variation of load of the mineral Electric - Wheeled Self-Dumping Truck, this paper designs the hydrostatic driving system of the heavy duty mineral Self-Dumping Truck using hydrostatic merits, refer to the 108t Electric-Wheeled self - Dumping Truck which produced by the Xiangtan Electric Manufacturing Corporation LTD. The Truck is four-wheel-drive vehicle type. There are four hydraulic motors output torque to drive vehicle. The hydraulic system which supplied flow and pressure by double-pumps is closed variable system. Due to the turning and dumping occur at different time, two pumps merge their flow to supply system when dumping. This means makes full use of engine power and reduces energy loss. Braking performance of the heavy duty mineral Self-Dumping Truck is also analyzed in this paper and it is meet the requirements of its braking. Keywords: The mineral Self-Dumping Truck, The Electric - Wheeled Self - Dumping Truck, Hydrostatic transmission I
