The invention provides a double-motor two-gear electric drive axle structure which comprises a first drive motor and a second drive motor which are arranged in a spaced mode; a two-gear speed reducing mechanism which comprises an input shaft, a first driving gear, a first driven gear, a first intermediate shaft, a second intermediate shaft, a clutch, a brake, a double-star planet row, a second driving gear and a second driven gear; and a differential. According to the structure, the double-motor and parallel-shaft structure arrangement is adopted, the axial length of the output shaft is reduced, whole-vehicle arrangement of an independently-suspended vehicle is facilitated, high and low gears are achieved on a double-star planet row after the motors are subjected to first-stage speed reduction, the transmission ratio is reduced, and the economical efficiency and gear shifting comfort of the vehicle are improved.

    提供了一种双电机两档电驱动桥结构,包括:第一驱动电机和第二驱动电机,相互间隔布置;两档减速机构,包括输入轴、第一主动齿轮、第一从动齿轮、第一中间轴、第二中间轴、离合器、制动器、双星行星排、第二主动齿轮与第二从动齿轮;以及差速器。该结构采用双电机和平行轴结构布置,减小了输出轴的轴向长度,有利于独立悬挂的车辆实现整车布置,电机经过一级减速后在双星行星排实现高低档有利于缩小传动间比,提高了车辆的经济性和换挡舒适性。
