The invention provides a gearbox special for a hybrid electric vehicle and the hybrid electric vehicle comprising the gearbox. The gearbox comprises an engine, a driving motor, a generator, a planetary gear set, a clutch, a differential mechanism, a speed reducer, an input outer shaft and an input inner shaft. The generator is arranged between the planetary gear set and the clutch, and the driving motor is arranged between the clutch and the engine. The first end of the input outer shaft is fixedly connected with the driving motor, the second end of the input outer shaft extends towards the engine, and the driving motor is fixedly connected with the input outer shaft; the first end of the input inner shaft is fixedly connected to the planetary gear set, and the second end of the input inner shaft sequentially penetrates through the generator rotor, the clutch and the driving motor rotor and then is connected with the engine. The speed reducer is connected to the input outer shaft between the driving motor and the engine, and the differential mechanism is fixedly connected with the speed reducer. By the adoption of the gearbox, coaxial arrangement of the two motors can be achieved, the axial space is saved, and meanwhile the problem that bearings between the inner shaft and the outer shaft are poor in lubrication can be effectively solved.

    本发明提供一种混合动力汽车专用变速箱及包含其的混合动力汽车,包括发动机、驱动电机、发电机、行星齿轮组、离合器、差速器、减速器、输入外轴和输入内轴:发电机布设在行星齿轮组和离合器之间,驱动电机布设在离合器和发动机之间;输入外轴第一端与驱动电机固定连接,输入外轴的第二端向发动机方向延伸,驱动电机与输入外轴固定连接;输入内轴第一端固定连接在行星齿轮组上,输入内轴第二端依次穿过发电机转子、离合器、驱动电机转子后连接发动机;减速器连接在驱动电机和发动机之间的输入外轴上,差速器与减速器固定连接。采用本发明的变速箱可以实现双电机同轴布置、节省轴向空间同时还可以有效避免内轴和外轴之间的轴承润滑不良问题。
