The invention discloses a dual-two-gear dual-motor hybrid power system which comprises an engine, a first motor and a second motor, wherein a first motor shaft of the first motor is connected with an output shaft of the engine through a transmission mechanism, and the transmission mechanism comprises a first clutch; a first gear shifting mechanism is arranged between the output shaft of the engine and an automobile driving shaft and comprises a transmission shaft, a second clutch, a third clutch and a differential mechanism arranged on an automobile output shaft; and a second motor shaft of the second motor is connected with the automobile driving shaft through a second gear shifting mechanism, and the second speed change mechanism comprises a single-row planet mechanism and a synchronizer. The four functions of engine two-gear driving, motor two-gear switching driving, generator decoupling and driving motor decoupling can be achieved. The power acceleration performance of high and low vehicle speeds can be better covered, and meanwhile, the economical efficiency is improved.

    本发明公开了一种双两档位双电机混动系统,包括发动机、第一电机、第二电机,所述第一电机的电机轴一与发动机的输出轴之间通过传动机构进行联接,所述传动机构包括离合器一;所述发动机的输出轴与汽车驱动轴之间设置有第一换挡机构,所述第一换挡机构包括传动轴、离合器二、离合器三和设置在汽车输出轴上的差速器;所述第二电机的电机轴二与汽车驱动轴通过第二换挡机构相联接,所述第二变速机构包括单排行星机构、同步器。本发明可以实现发动机两档位驱动、电机两档位切换驱动、发电机解耦及驱动电机解耦等四个功能。可以更好的覆盖高低车速的动力加速性,同时提高经济性。
