摘要:当前国内外对于电动汽车的设计研究大都延用了传统的内燃机汽车底盘系统,其动力传动系统、驱动系统、行驶系统的设计都与传统的内燃机汽车大体一致。但是,这种设计思路存在着底盘系统结构复杂、制造成本高、动力损耗大及维修不便等不足。基于此,设计研究五轮结构的新型五轮电动汽车,采用单轮驱动装置,两前两后轮设为被动轮,简化了底盘系统,降低了动力损耗,对电动汽车技术发展具有一定的参考价值。

Abstract: The design and research of electric vehicle at home and abroad mostly use the traditional internal combustion engine vehicle chassis system, the design of its power transmission system, drive system and driving system are generally consistent with the traditional internal combustion engine vehicle. However, there are some disadvantages in this design, such as complicated structure of chassis system, high manufacturing cost, large power loss and inconvenient maintenance. Based on this, a new five-wheel electric vehicle with a five-wheel structure is designed and studied. The single-wheel drive device is adopted and the two front and rear wheels are set as passive wheels, which simplifies the chassis system and reduces the power loss, it has certain reference value to the development of electric vehicle technology.

为了解决能源危机和全球气候变暖的急剧恶化,追求汽车产业技术转型与升级,满足当今汽车产业绿色发展的迫切需求,电动汽车俨然成为全球各大汽车厂商必争的战略高地[1]。我国自2012年发布《节能与新能源汽车产业发展规划(2012—2020年)》到《新能源汽车产业发展规划(2021—2035年)》,国家长期坚持纯电驱动战略方向,电动汽车必将成为新能源汽车产业发展主流[2]。

近年来,电动汽车也取得了瞩目的成绩,2019年国内电动汽车新车销量达110万辆左右,2020年国内电动汽车新车销量达130万辆左右,增长18.2%。

电动汽车具备自身独特的优势,是传统燃油车在现有技术基础上无法突破与实现的。

①是无污染、噪音低:电动汽车动力是由电力转化,实现零排放、无污染;电动汽车运行过程中的噪声值比传统燃油车低20分贝左右。

②起步加速快:电动汽车0-100km/h加速时间一般为6-8s,传统燃油车一般为11-14s。……
