The invention provides a double-planet-row electric drive assembly. The double-planet-row electric drive assembly comprises a shell; the driving mechanism is arranged in the shell and comprises a hollow shaft and a motor for driving the hollow shaft to rotate; the double-planet-row two-gear transmission is connected with the driving mechanism and comprises a first planet row and a second planet row; the differential mechanism is connected with the second planet row, and the two ends of the differential mechanism are connected with a first half shaft and a second half shaft respectively. The four modes of a neutral gear, a low gear, a high gear and parking can be achieved, braking energy recovery can be achieved, and economical efficiency is improved while the advantage that power is not interrupted in the gear shifting process is kept; the adopted hollow shaft motor can guarantee that power input and power output are coaxial, the transmission efficiency is improved, and the integration degree is improved.
本发明提出了一种双行星排电驱动总成,包括外壳;设在所述外壳内的驱动机构,所述驱动机构包括中空轴以及带动所述中空轴转动的电机;连接所述驱动机构的双行星排两档变速器,所述双行星排两档变速器包括第一行星排和第二行星排;以及连接所述第二行星排的差速器,所述差速器的两端分别连接第一半轴和第二半轴。本发明能够实现空挡、低速档、高速档、驻车四种模式,且能实现制动能量回收,这保持了换挡过程的动力无中断优点的同时,提升了经济性;采用的中空轴电机能保证动力输入、输出的同轴,提高了其传动效率且提高了集成度。
