The invention discloses a longitudinally-arranged series-parallel gearbox assembly and a hybrid electric vehicle. The gearbox assembly comprises a driving motor, a mode clutch, a generator, a split clutch and an engine which are longitudinally, coaxially and sequentially arranged. A hollow shaft of the driving motor sleeves a second shaft and is coaxial with the second shaft, a first gear is arranged on the hollow shaft, the first gear transmits power of the driving motor to a fourth gear after being decelerated by a speed reducer, and the fourth gear is fixedly connected to the end part of the second shaft; the mode clutch is mounted between a first shaft and the second shaft; and the generator is installed on the first shaft, and the engine is connected with the generator through a split clutch. According to the technical scheme, the vehicle can be driven in different modes according to the working conditions of the vehicle, the driving motor is a high-rotating-speed, large-torque and high-power-density motor, the system weight is reduced, oil ways in the gearbox are shared, motor cooling and gear and bearing forced lubrication are achieved, and the system integration degree and efficiency are high.

    本发明公开了一种纵置混联变速箱总成和混合动力汽车,其中变速箱总成包括纵向同轴依次设置的驱动电机、模式离合器、发电机、切分离合器和发动机;驱动电机的中空轴套设在第二轴上,与第二轴同轴设置,且中空轴上设置有第一齿轮,第一齿轮经减速器减速后将驱动电机的动力传递到第四齿轮,第四齿轮固定连接在第二轴的端部;模式离合器安装在第一轴和所述第二轴之间;发电机安装在所述第一轴上,发动机与发电机通过切分离合器联接。上述技术方案可以根据车辆工况,采用不同的模式驱动车辆,且驱动电机采用高转速大扭矩高功率密度电机,降低系统重量,而变速箱内油路共享,实现电机冷却、齿轮和轴承强制润滑,系统集成度高、效率高。
