摘　　要：在现有纯电动汽车直驱结构中增加锥环式无级变速器,形成一整套紧凑的集成驱动系统,同时在满足整车动力性要求的前提下对驱动电机进行选型与匹配,对装配该驱动系统的纯电动汽车进行动力性计算和校核,并采用ADVISOR软件对整车性能进行仿真并实车测试。结果表明:所选动力电机与该款变速器搭配后可使目标车辆最高车速达到120km/h,最大爬坡度为57.69%,EUDC工况法测得的百公里能耗为13.46kW·h,续驶里程达到140km,满足设计要求。In the existing direct drive structure of pure electric vehicle,the cone-ring transmission（KRG）was added to form a complete set of compact integrated drive system,and the drive motor was selected and matched under the premise of satisfying the power requirements of the whole vehicle.Then the dynamic performance calculation and check were carried out for the electric vehicle equipped with the drive system.Finally,the ADVISOR software was used to simulate the vehicles performance and test the actual vehicle.The results show that the selected power motor equipped with KRG enables the target vehicle to reach the maximum speed of 120 km/h,the maximum gradient of 57.69%,the driving range up to 140 km and the energy consumption of 13.46 kW·h by EUDC loading method.All those cases met the design requirements.
