The invention discloses a longitudinal front-drive power split hybrid power speed change system which comprises an input shaft, a first motor, a second motor, a differential mechanism, an output shaft and a planetary gear train, the output shaft is connected with the differential mechanism, the input shaft is connected with an input bevel gear, and the planetary gear train is connected with the differential mechanism. The input bevel gear is associated with the planetary gear train, a rotating shaft of the first motor is associated with a sun gear of the planetary gear train, and a rotating shaft of the second motor is associated with a planet carrier or a gear ring of the planetary gear train. Stepless speed change can be achieved, an engine can intervene earlier in the low-speed stage, power performance is provided, the engine is driven efficiently in the high-speed stage, and the fuel economy of the whole vehicle is improved; and the structure is compact, the occupied axial and radial space is small, and the arrangement of a hybrid power system of a vehicle with a longitudinally-arranged engine is facilitated.

    本发明公开了一种纵置前驱功率分流混合动力变速系统,包括输入轴、第一电机、第二电机、差速器、输出轴以及行星齿轮系,所述输出轴与差速器相连,所述输入轴上连有输入锥齿轮,行星齿轮系与差速器相连,输入锥形齿轮与行星齿轮系相关联,所述第一电机的转轴与行星齿轮系的太阳轮相关联,所述第二电机的转轴与行星齿轮系的行星架或齿圈相关联。其能实现无级变速,发动机可以在低速阶段更早介入,提供动力性,高速阶段发动机高效驱动,提高整车燃油经济性;并且结构紧凑,轴向和径向空间占用少,易于发动机纵置车型的混动系统布置。
