在露天煤矿开采现场,已经很少能看见人工劳动,取而代之的是矿用卡车、电铲和拉斗铲三大“巨人”忙碌的身影。其中,矿用卡车是矿山开采过程中非常重要的运输工具,其性能的优劣直接影响到矿山的开采效率和运营成本。而驱动系统作为矿用卡车的灵魂,是保障“巨人”高效运作的基础,在矿用卡车性能方面起着举足轻重的作用。矿用卡车根据驱动方式不同可分为机械式矿用卡车和电动轮矿用卡车两种,由于电动轮矿用卡车具有结构简单、驱动力和电制动力强劲、配件损耗少、节省燃油等特点, In the open-pit coal mining scene, few have seen artificial labor, replaced by mining trucks, shovels and dragline three “giant” busy figure. Among them, mining trucks are very important transportation tools in the mining process. Their performance will directly affect the mining efficiency and operating cost. The drive system as the soul of mining trucks, is to protect the “giant” efficient operation of the foundation, in mining truck performance plays a decisive role. Mining trucks can be divided into mechanical mining trucks and electric mining trucks with different driving modes. Because the electric mining truck has the advantages of simple structure, strong driving force and electric braking force, less parts loss and fuel saving ,
