The invention provides a dual-motor hybrid power variable speed driving system. The dual-motor hybrid power variable speed driving system comprises an engine, a clutch, a first motor, a second motor,a first speed reducing mechanism, a second speed reducing mechanism, a power output mechanism, a first input shaft, a second input shaft, a second-gear driving gear, a first-and-second-gear synchronizer, a first-gear driving gear, a differential mechanism, a first inverter, a second inverter, a battery, a wiring harness and a parking system, the first motor can be connected with the first input shaft through a first speed reducing mechanism; one end of the first input shaft can be connected with an engine; a clutch is arranged between the first input shaft and the second input shaft; a second-gear driving gear, a first-gear synchronizer, a second-gear synchronizer and a first-gear driving gear are installed on the second input shaft, the first-gear driving gear or the second-gear driving gear can be connected with the differential mechanism through the power output mechanism, and the second motor can be connected with the power output mechanism or the differential mechanism through thesecond speed reducing mechanism. Different working condition modes can be adopted as required to improve the fuel economy.

    本发明提供了一种双电机混合动力变速驱动系统,包括发动机、离合器、第一电机、第二电机、第一减速机构、第二减速机构、动力输出机构、第一输入轴、第二输入轴、二档主动齿轮、一二档同步器、一档主动齿轮、差速器、第一逆变器、第二逆变器、电池、线束和驻车系统,第一电机可通过第一减速机构与第一输入轴连接,第一输入轴的一端可与发动机连接,第一输入轴与第二输入轴之间设有离合器,第二输入轴上安装有二档主动齿轮、一二档同步器及一档主动齿轮,一档主动齿轮或二档主动齿轮可通过动力输出机构与差速器连接,第二电机可通过第二减速机构与动力输出机构或差速器连接。本发明可根据需要采用不同工况模式以提高燃油经济性。
