【摘 要】汽车目前对我们生活来说十分关键,随之而来的,生产制造技术也在不停创新中,特别是电动汽车生产越来越多,已经不再单纯是研发阶段,而到了量化生产的时刻。为让电动汽车运行更加安全,应及时分析轮毂电机的普遍故障及原因,并通过有效技术诊断,最后选中一个适当的对策维护,尽快排除故障,防止出现更深入的影响,因此,论文对电动汽车轮毂电机故障诊断进行研究。
【Abstract】Automobile is very important to our life at present. Along with it, the production and manufacturing technology is constantly innovating, especially the electric automobile production is more and more, which is no longer just the stage of research and development, but the moment of quantitative production. In order to make the operation of electric automobile safer, we should analyze the common faults and causes of hub motor in time, and through effective technical diagnosis, finally select an appropriate countermeasure for maintenance, and eliminate the faults as soon as possible to prevent further impact. Therefore, this paper studies the fault diagnosis of hub motor of electric automobile.

1 引言
现在市场上出现了不少新能源汽车,代表是混合动力与纯电动新能源汽车,并且备受市场喜爱。对纯电动汽车而言,诊断轮毂电机的故障以及选择维护技术时,需要注意和之前的选择不同。为确保维修效果,应该尽可能专业化,并充分考虑纯电动汽车的特点,选择可靠的技术进行维护,防止故障给汽车运行带来阻碍。不过,由于之前的汽车维修人员缺乏深入的维修知识,在新能源汽车维修方面经验不足,因此,希望本文中提出的诊断对策可以给该领域带来一定的借鉴价值。
2 故障现象的分析与诊断
某轮毂驱动式纯电动汽车的用途是科研,运行时忽然降低了动力,没有需要的动力来继续进行加速、爬坡等动作。检查分析:通过举升机举起车辆后,发现挂前进挡与倒挡,用脚踩进行加速,车辆后轮中的右轮没有反应,所以先判断为右轮动力系统出现问题[1]。……
