双转子混合动力系统研究

开发出一种以双转子电机为动力耦合器的混合动力系统。样机试验证明该系统能够实现混合动力汽车所要求的各项功能,而且制造成本低廉。其特点是:发动机独立于车轮运转,可始终在高效区工作;发动机的动力主要通过电磁力直接传给驱动桥,仅有少部分动力经过机械能—电能—机械能的转换,降低了能量转换过程中的损失;且该系统兼备无级变速器的功能。

A Study on Hybrid Power System with Double Rotor Motor

A novel hybrid power system with a double rotor motor as drive coupler is developed.The prototype test shows that the system can meet all functional requirements of hybrid electric vehicles with low manufacturing cost.The main features of the system are as follows:(1)There is no direct mechanical connection between engine and wheel,so the engine can be adjusted to work at high efficiency zone.(2)The power of the engine can be transmitted to driving axle directly by the electromagnetic force,and only part of power is converted from mechanical energy into electric energy,so the power losses in energy conversion can be reduced.(3)The system can also operate as electronic continuously variable transmission.
