The invention discloses a driving method of an engine-flywheel power coupling system.The system comprises an engine, a power dividing system, a stepless speed change system and a flywheel energy storage system.The power dividing system comprises three sets of planetary gear mechanisms, and due to the fact that the multiple sets of planetary gear mechanisms output in a coupling mode, the power dividing system can drive the flywheel to rotate; the coupling relation between the engine rotating speed and the flywheel rotating speed and the main speed reducer rotating speed is controlled by changing the transmission ratio of the stepless speed change system, then power distribution among the engine power, the flywheel energy storage system power and the main speed reducer power is adjusted, and finally switching of the driving modes of the hybrid power system is achieved. According to the engine-flywheel power coupling system, a complete hybrid power function can be provided within a large speed range, and therefore high fuel economy and acceleration performance are achieved.

    本发明公开了一种发动机‑飞轮动力耦合系统的驱动方法,系统包括发动机、功率分流系统、无级变速系统和飞轮储能系统,所述功率分流系统包括三组行星齿轮机构,由于多组行星齿轮机构耦合输出,通过改变无级变速系统的传动比控制发动机转速和飞轮转速与主减速器转速之间的耦合关系,进而调整发动机功率,飞轮储能系统功率与主减速器功率之间的功率分配,最终实现混合动力系统驱动模式的切换。本发明发动机‑飞轮动力耦合系统能够实现在大速度范围内都能提供完全的混合动力功能,从而实现较高的燃油经济性和加速性能。
