The embodiment of the invention discloses a coaxial two-gear planet row electric drive axle for an automobile. The electric drive axle comprises a sun gear, a plurality of planet gears, a planet carrier, a gear ring, a synchronizer, a differential mechanism, a synchronizer gear shifting motor and a drive motor which are installed in a shell. The sun gear, the planet carrier, the gear ring, the differential mechanism and the synchronizer are coaxial, the axis of each planet gear is parallel to the axis of the sun gear, a power output shaft of the driving motor is connected with the sun gear, the sun gear is externally meshed with the plurality of planet gears, the planet gears are installed on the planet carrier and are internally meshed with the gear ring, the gear ring is fixedly installed on the inner wall of the shell, the synchronizer gear shifting motor is connected with the synchronizer, and the synchronizer is connected with the differential mechanism. By applying the scheme provided by the embodiment of the invention, when the torque and the rotating speed input by the driving motor are not changed, the high torque and the low rotating speed can be output, and the low torque and the high rotating speed can also be output, so that the driving requirements of different road conditions can be met.

    本发明实施例公开一种用于汽车的同轴式两档行星排电驱动桥。该电驱动桥包括安装于壳体内的太阳轮、多个行星齿轮、行星架、齿圈、同步器、差速器、同步器换挡电机和驱动电机,太阳轮、行星架、齿圈、差速器和同步器同轴,每个行星齿轮的轴线与太阳轮的轴线平行,驱动电机的动力输出轴与太阳轮连接,太阳轮与多个行星齿轮外啮合,多个行星齿轮安装于行星架,多个行星齿轮与齿圈内啮合,齿圈固定安装于壳体的内壁,同步器换挡电机与同步器连接,同步器与差速器连接。应用本发明实施例提供的方案,在驱动电机输入的扭矩和转速不变时,既可以输出高扭矩和低转速又可以输出低扭矩和高转速,可以满足不同路况的驾驶需求。
