A heavy truck electric drive axle transmission system comprises a first driving motor, a first speed reducing mechanism and a planet row speed reducing mechanism which are sequentially in transmission connection, the output end of the first driving motor is in transmission connection with the first speed reducing mechanism, and the output end of the first speed reducing mechanism is in transmission connection with a sun gear of the planet row speed reducing mechanism. And a planet carrier of the planet row speed reducing mechanism is connected with the output half shaft and a driving wheel. According to the heavy truck electric drive axle transmission system, the planet row is combined with the parallel shaft speed reducing mechanism to serve as a transmission mechanism, and large speed reducing and torque increasing output can be achieved. The intermediate shaft of the parallel shaft speed reducing mechanism can be used as a multi-motor torque input confluence shaft, and the planet row speed reducing mechanism can converge the output torque of the plurality of parallel shaft speed reducing mechanisms, so that corresponding expansion can be carried out according to the actual power torque output requirement of a vehicle; therefore, the electric drive axle transmission system has good flexibility and expansibility.

    一种重卡电驱桥传动系统,包括依次传动连接的第一驱动电机、第一减速机构以及行星排减速机构,所述第一驱动电机输出端和第一减速机构传动链接,第一减速机构输出端和行星排减速机构的太阳轮传动连接,行星排减速机构的行星架和输出半轴连接并连接驱动轮。本发明提出的重卡电驱桥传动系统,采用了行星排结合平行轴减速机构作为传动机构,可以实现较大的减速增扭输出。平行轴减速机构的中间轴可以作为多电机扭矩输入汇流轴,而行星排减速机构则可将多个平行轴减速机构的输出扭矩汇流,从而可以根据车辆实际功率扭矩输出需求而进行相应拓展,因此该电驱桥传动系统具有良好的灵活性和可拓展性。
