The invention discloses a dual-motor high-low speed interval power system. A first motor drives a planetary mechanism; the planetary mechanism and/or a second motor drive/drives a first input gear; the first input gear drives a differential mechanism or a drive axle to output power; power output of a vehicle is achieved by superposing the second motor on the basis that the first motor drives the planetary mechanism, the double motors can work independently to achieve multi-speed-stage driving, the acceleration performance can be guaranteed through combined complementation, power arrangement ismore flexible, energy distribution is more reasonable, and the energy saving performance and the power performance are both considered.
本发明公开了一种双电机高低速区间动力系统,其第一电机驱动行星机构,行星机构和/或第二电机传动第一输入齿轮,第一输入齿轮传动差速器或驱动桥以输出动力,车辆动力的输出是在第一电机驱动行星机构的基础上叠加第二电机,双电机既能够独立工作以实现多速级行驶,也能够联合互补保证加速性能,动力布置更灵活、能量分配更合理,兼顾节能性和动力性。
