The invention relates to a dual-motor multi-mode driving system based on planetary gears. The dual-motor multi-mode driving system comprises a driving motor I, an input shaft I, a driving motor II, an output shaft II, a double-row single-sun-gear planetary gear mechanism, a brake I, a brake II, a gear train shell and a transmission mechanism. The driving motor I is connected to a sun gear of the double-row single-sun-gear planetary gear mechanism through an input shaft I; the driving motor II is connected to a gear ring of the double-row single-sun-gear planetary gear mechanism through an input shaft II; the brake I works to brake a major planet carrier of the double-row single-sun-gear planetary gear mechanism, and the brake II works to brake a gear ring of the double-row single-sun-gear planetary gear mechanism. A small planet carrier of the double-row single-sun-gear planetary gear mechanism serves as an output component of the mechanism and is connected with a transmission mechanism, and power is output to drive an automobile. The system can realize five driving modes, so that a plurality of driving modes can be selected in the driving process of the automobile, and different driving requirements are met.

    本发明涉及一种基于行星齿轮的双电机多模式驱动系统,包括驱动电机Ⅰ、输入轴Ⅰ、驱动电机Ⅱ、输出轴Ⅱ、双排单太阳轮行星齿轮机构、制动器Ⅰ、制动器Ⅱ、轮系壳体和传动机构;所述驱动电机Ⅰ由输入轴Ⅰ连接至双排单太阳轮行星齿轮机构的太阳轮;所述驱动电机Ⅱ由输入轴Ⅱ连接至双排单太阳轮行星齿轮机构的齿圈;所述制动器Ⅰ工作可将双排单太阳轮行星齿轮机构的大行星架制动,制动器Ⅱ工作可将双排单太阳轮行星齿轮机构的齿圈制动;所述双排单太阳轮行星齿轮机构的小行星架作为机构的输出构件与传动机构连接,输出动力驱动汽车。该系统可实现五种驱动模式,使汽车在行驶过程中有多种驱动模式可选择,满足不同的驾驶需求。
