The invention discloses a multi-planet-row hybrid power gearbox configuration. The multi-planet-row hybrid power gearbox configuration comprises two motors, five planet rows and an engine. The five planet rows are sequentially arranged, a first clutch and a second clutch are arranged between the first planet row and the second planet row, and a first brake, a second brake and a third brake are arranged at the corresponding positions of the second planet row, the third planet row and the fourth planet row respectively. One motor and the engine are in transmission connection with the first planet row, and the other motor is in transmission connection with the fifth planet row. The first planet row is used for power dividing, a middle speed change mechanism is consistent with a hydraulic automatic box in structure, six forward gears can be achieved, the speed ratio of the mechanical working condition is increased, the fifth planet row is used for increasing the output torque of the second motor, and the first motor and the second motor work in different combined working modes. The high dynamic property requirement of the vehicle under the special working condition and the low fuel property requirement of the vehicle under the conventional working condition are met.
本发明公开了一种多行星排混合动力变速箱构型,包括两个电动机、五个行星排和发动机。五个行星排依次排列布置,第一行星排与第二行星排之间设有第一离合器和第二离合器,第二行星排、第三行星排和第四行星排对应位置分别设置有第一制动器、第二制动器和第三制动器。一个电动机和发动机与第一行星排传动连接,另一个电动机与第五行星排传动连接。第一行星排用于功率分流,中间变速机构与液力自动箱结构保持一致,可实现6个前进挡,扩大机械工况的速比,第五行星排用于增加第二电动机的输出扭矩,第一电动机、第二电动机通过不同的组合工作方式,实现车辆特殊工况的高动力性要求和常规工况的低燃油性需求。
