The invention provides a hybrid electric driving device. The hybrid electric driving device comprises an engine, a first motor, a second motor, a first planetary line, a second planetary line, a shuntspeed change mechanism and an output shaft. The first planetary line comprises a first sun wheel, a first planet carrier and a first gear ring. The second planetary line comprises a second sun wheel,a second planet carrier and a second gear ring. The first planet carrier is fixedly connected with the second planet carrier and is connected with the engine, the first sun wheel is fixedly connectedwith the second sun wheel and is connected with the first motor, the shunt speed change mechanism can selectively connect the first gear ring and/or the second gear ring with the output shaft, and therefore power output by the first gear ring and/or the second gear ring and the power of the second motor are converged and then output to drive vehicle wheels. According to the hybrid electric driving device, by means of the arranged two planetary lines and shunt speed change mechanism, multiple work modes can be achieved, and therefore the performance of the hybrid electric driving device is improved.
本发明提供了一种混合电驱动装置,其包括:发动机、第一电机、第二电机、第一行星排、第二行星排、分流变速机构和输出轴,第一行星排包括第一太阳轮、第一行星架和第一齿圈,第二行星排包括第二太阳轮、第二行星架和第二齿圈,第一行星架与第二行星架固接并与发动机连接,第一太阳轮与第二太阳轮固接并与第一电机连接,分流变速机构可选择性地将第一齿圈和/或第二齿圈与输出轴连接,从而将经由第一齿圈和/或第二齿圈输出的动力与第二电机的动力汇流后输出驱动车轮。本发明的混合电驱动装置,通过设置的两个行星排和分流变速机构,可以实现更多种工作模式,从而提高了混合电驱动装置的性能。
