轮边驱动电机专利技术发展

Development of patent technology of in-wheel motor

利用轮边电机直接驱动电动汽车采用轮边电机,避免了机械传动系统中的能量损失,使电能得到了最大的利用。电动汽车采用轮边直驱式可立即产生旋转动力,减少了加速时间,并且对每个车轮实施单独控制非常方便,具有较高的灵敏度。本文主要以DWPI专利数据库以及CNABS数据库中的检索结果为分析样本,从专利文献的视角对轮边驱动电机的技术发展进行了全面的统计分析,总结了与轮边驱动电机相关的国内和国外专利的申请趋势、主要申请人分布以及重点技术分支:轮边驱动电机的发展路线做了一定的分析,并从中得到一定的规律。

Driving the electric vehicle by in-wheel motor directly,the energy loss of transmission system is evitable and the electric power is greatly saved.Circumrotate momentum is generated immediately by inwheel motor system.This paper mainly to DWPI patent database and CNABS database retrieval results for the analysis of the sample,from the patent literature from the perspective of the development of in-wheel motor system were comprehensive statistical analysis,summarized and in-wheel motor related domestic and foreign patent application trend,mainly distributed in the applicant and the main development route do some analysis, and the obtained certain rules.
