The invention discloses a nested double-planet-row electric driving system, and relates to the technical field of electric automobiles. A nested double-planet-row electric driving system comprises a motor and a double-planet-row speed reducing mechanism, and the motor comprises a rotating shaft; the double-planet-row speed reducing mechanism comprises a first planet row and a second planet row, wherein the first planet row is arranged on the rotating shaft in a sleeving mode and is in transmission connection with the rotating shaft, the second planet row is arranged on the periphery of the first planet row in a sleeving mode and is in transmission connection with the first planet row, and an output shaft far away from the rotating shaft is arranged on the second planet row. According to the technical scheme, the structure that the second planet row is arranged on the periphery of the first planet row in a sleeving mode and is in transmission connection with the first planet row is adopted, so that the double-planet-row speed reducing mechanism is distributed in the radial direction, the overall structure is more compact, the axial occupied space is effectively reduced, carrying performance is improved, more arrangement space is provided for a battery, and the service life of the battery is prolonged. And the cruising ability of the whole vehicle is further improved.

    本发明公开了一种嵌套式双行星排电驱动系统,涉及电动汽车技术领域。一种嵌套式双行星排电驱动系统,包括:电机、以及双行星排减速机构,所述电机包括转轴;所述双行星排减速机构包括套设在所述转轴上且与所述转轴传动连接的第一行星排、以及套设在所述第一行星排的外周且与所述第一行星排传动连接的第二行星排,所述第二行星排上设置有远离所述转轴的输出轴。本发明的技术方案通过采用第二行星排套设在第一行星排的外周且与第一行星排传动连接的结构,使得双行星排减速机构沿着径向分布,整体结构更为紧凑,有效减少了轴向占用空间,提升了搭载性,为电池提供更多的布置空间,进一步提升整车的续航能力。
