The invention discloses a dual-motor hybrid power transmission system and a hybrid electric vehicle. Wherein a generator is connected with a sun gear of the first planetary gear set; an engine is connected with the first planetary gear set planet carrier; the engine is connected with the driving end of a first clutch; the engine is connected with the driving end of the second clutch; the driven end of the first clutch is connected with the generator; the driven end of the second clutch is connected with the driving motor; the driving motor is connected with a sun gear of the second planetary gear set; a planet carrier of the second planetary gear set is connected with a gear ring of the first planetary gear set; the first planetary gear set gear ring is connected to the output end; the second planetary gear set ring gear is fixed relative to the vehicle body. According to the system, the two independent clutches and a double-row planetary mechanism are adopted to form a two-gear mode and an ECVT mode, and the acceleration power performance is obviously improved; the high-speed engine is directly driven, so that no extra energy loss is caused, and the oil consumption of the whole vehicle is favorably improved; and the control is simple.

    本申请公开了一种双电机混合动力传动系统及混合动力汽车;其中,发电机与第一行星齿轮组的太阳轮连接;发动机与第一行星齿轮组行星架连接;发动机与第一离合器主动端连接;发动机与第二离合器主动端连接;第一离合器被动端与发电机连接;第二离合器被动端与驱动电机连接;驱动电机与第二行星齿轮组太阳轮连接;第二行星齿轮组行星架与第一行星齿轮组齿圈连接;第一行星齿轮组齿圈连接到输出端;第二行星齿轮组齿圈相对于车身固定。本发明采用两个单独离合器与双排行星机构形成两档模式和ECVT模式的混动变速器,加速动力性明显改善;高速发动机直驱,从而无额外的能量损耗,有利于改善整车油耗;且控制简单。
