一种带后辅助支撑的集成式壳体电机增程器
技术领域
本发明属于发动机技术领域，具体涉及一种带后辅助支撑的集成式壳体电机增程器。
背景技术
节能和环保是汽车领域永恒的主题，众所周知纯电动汽车受目前动力电池比能量较小、价格高等因素的影响，续驶里程不能满足远距离出行，人民对纯电动汽车存在里程焦虑。增程器能有效解决纯电动汽车里程焦虑问题，已经成为新能源汽车发展趋势。增程器一般由发动机+发电机组成。其中，发动机的曲轴通过一个电磁离合器与电机连接，就是采用电机直接通过扭减连接到发动机上，虽然扭减集成到转子组件中，但长度上依旧没有优势，并且增加了一个扭减的成本；其次，转子组件的稳定性与可靠性不足。
如公开号为CN208664976U的中国实用新型专利公开了一种电机集成式电动汽车用增程器，该结构作为上一代增程器技术，直接取消了飞轮，通过减少零件实现长度缩短，但也会带来弊端；同时，在长时间工作运行环境下，存在转子组件的可靠性和稳定性变差的问题。
发明内容
