The invention belongs to the technical field of hybrid power gearboxes, and relates to a single-motor hybrid power gearbox and a control method thereof, the single-motor hybrid power gearbox comprises two power sources, namely an engine and a driving motor, which are coaxially arranged, and further comprises a gear transmission system consisting of a planet row, two brakes, an electromagnetic clutch, an output shaft and a differential mechanism. A planet carrier in the planet row is connected with an engine through an input shaft, a sun gear is connected with a rotor shaft spline of a driving motor, and the engine drives a transmission gear, an output shaft and a differential mechanism to jointly form a single-motor hybrid power driving system. On one hand, the functions of pure electric driving of the driving motor, power generation of the driving motor driven by the engine and multi-gear driving of the engine can be achieved by controlling the planet row through the electric control braking system, and on the other hand, compared with a traditional dual-motor hybrid power transmission scheme, a single-motor hybrid power scheme with complete functions is adopted. And the production cost of the transmission can be greatly reduced.

    本发明属于混合动力变速箱技术领域,由一种单电机的混合动力变速箱及其控制方式,包括同轴设置的发动机和驱动电机两个动力源,还包括由一个行星排、两个制动器、一个电磁离合器以及输出轴和差速器构成的齿轮传动系统。所述行星排中的行星架通过输入轴与发动机连接,太阳轮与驱动电机转子轴花键连接,以及发动机驱动传动齿轮、输出轴和差速器,共同构成一个单电机混合动力驱动系统;本发明一方面可以通过电控制动系统对行星排的控制,可以实现驱动电机纯电驱动、发动机驱动驱动电机发电以及发动机多档位驱动的功能,另一方面相对传统的双电机混合动力变速器方案,功能完善的单电机混合动力方案,可以大幅度降低变速器的生产成本。
