Description

助力电动汽车的电动机结构
所属技术领域
本实用新型属于一种电动机，尤其是一种用于电力动力驱动的助力电动汽车的电动机。
背景技术
由于电力动力驱动的助力电动汽车的电动机是直接驱动球笼轴的，而球笼轴经常处于震动和轴心不定状态中运转，所以对结构有特殊要求。
发明内容
为了解决背景技术中环境对电动机的不利影响，本实用新型提供了一种助力电动汽车的电动机结构，助力电动汽车的电动机的转子设计在球笼轴上，定子外壳通过吊挂弹簧与助力电动汽车的机架连接。
本实用新型解决其技术问题采用的技术方案是：助力电动汽车的电动机转子轴两端为球笼轴的万向轴节，定子外壳与机架的固定采用弹簧吊挂柔性连接方式。
本实用新型的有益效果是：解决了震动和轴心不定的工作状态对电机的影响，实现了电动机对车轮的直接驱动。
附图说明。
下面结合附图和实施例对本实用新型进一步说明：
图1是助力电动汽车的电动机结构示意图
图1中，1.球笼轴，2.右端盖，3.定子外壳，4.转子，5.左端盖，6.霍尔总成，7.吊挂弹簧。
具体实施方案
