摘要：纯电动汽车作为一种新的出行工具选择对于能量安全和多样化有重要作用。然而,有限的行驶里程对纯电动的广泛运用形成了巨大阻碍。此探讨针对二驱纯电动汽车的传动系统进行浅析,以试图延长电动汽车的行驶里程。纯电动汽车拓扑结构设计包括两方面：传动系统零部件的选择和零部件的布置方式。为评价不同的传动系统拓扑结构,根据中国目前的技术水平,本探讨定义了两个新的评价指标：能量经济性和生命周期碳排放。本探讨建立了电动汽车各种拓扑结构的工程模型,并对模型进行了验证。对各种传动系统拓扑结构进行优化后获得了最佳的性能体现。此外,本探讨对影响汽车系统性能的影响因子进行了敏感性浅析,分别选择汽车设计参数车重和汽车动力性能参数最高车速的影响。结果显示1)双轮毂电机无减速器传动系统的电动汽车性能在优化后有最大幅度的提升,安装此种传动系统的电动汽车也最具备能源经济性,碳排放最少；2)与传统的内燃机汽车性能相比较,电动汽车在能源经济性上显示出了非常显著的优势,但是在生命周期碳排放的体现上电动汽车没有显示出显著降低,这产生于中国目前电力系统对煤能源的重大依赖；3)汽车整车整备质量对电动汽车的能源消耗和碳排放性能有较大的影响,而转变汽车最大速度的要求对电动汽车的性能体现没有产生较大的影响。关键词：
