摘　　要：为了提高电动叉车的续航里程及动力性能,提出了加装两挡变速器的传动方案。首先,基于驱动电动机的外特性与效率特性提出了两挡传动系统参数匹配方法;其次,以某型电动叉车为研究对象,对其驱动系统进行了改进:在不改变驱动电动机各项参数的基础上,将传动系统由一挡改为两挡,并对主减速比及变速器的两挡减速比进行匹配;最后,利用ADVISOR软件对电动叉车进行了平衡重式叉车循环工况仿真分析。结果显示,在不改变驱动电动机各项参数的基础上加装两挡变速器,可提升整个电动叉车的动力性和经济性;车速由0加速到最高车速的时间缩短了0.4s,满载爬坡度提高了2.5%,2小时叉车等效工况循环的电池能耗降低了3.5%。In order to improve the range of the electric forklift and climbing performance,a transmission scheme with a two speed gearbox was proposed in this study.First of all,based on the external characteristics and efficiency characteristics of the drive motor,a two-speed transmission system parameter matching method was proposed.Secondly,taking an electric forklift as the research object,its drive system was changed:on the basis of not changing the various parameters of the driving motor,change the transmission system from one gear to two gears,and match the main reduction ratio and the two gear reduction ratios of the transmission.Finally,using ADVISOR software to counterbalance electric forklift driving cycles simulation analysis.Results show that installing a two speed gearbox without changing the parameters of the driving motor can improve the power performance and fuel economy of the whole electric forklift;the acceleration time from zero to the maximum speed increases by 0.4 seconds,the full load climbing slope increases by 2.5%,and the battery energy consumption of the 2-hour equivalent working cycle of the forklift decreases by 3.5%.
