The invention discloses an electric driving structure of an axle and the axle. The electric driving structure of the axle comprises an axle housing, a motor, a half shaft, a gear reducer and a planetary reducer. The body part of the motor is fixed on the axle housing; the gear reducer comprises a first gear driven by a motor and a second gear linked with the first gear, and the second gear is synchronously connected with a rotating shaft; the planetary reducer comprises a sun gear, a planetary support, a planetary gear and a gear ring, the sun gear sleeves the rotating shaft, and the planetary support is pivoted to the axle housing; the half shaft penetrates through the rotating shaft and is in pivot fit with the rotating shaft; the half shaft is synchronously connected with the planetary bracket; and a connecting assembly is arranged between the rotating shaft and the sun gear and can move between a first position for synchronously connecting the rotating shaft and the sun gear and a second position for mutually disconnecting the rotating shaft and the sun gear. According to the invention, the motor can be protected, the structure of the axle is simplified, the overall size of the axle is reduced, and the arrangement of the high-power motor on the axle is facilitated.

    本发明公开了一种车桥的电驱动结构及车桥,车桥的电驱动结构包括桥壳、电机、半轴、齿轮减速器、行星减速器;电机的机体部分固定在桥壳上;齿轮减速器包括由电机驱动的第一齿轮、与第一齿轮联动的第二齿轮,第二齿轮上同步联接有转轴;行星减速器包括太阳轮、行星支架、行星齿轮、齿圈,太阳轮套设在转轴,行星支架枢接在桥壳上;半轴穿接在转轴内并与转轴枢转配合,半轴与行星支架同步联接;转轴与太阳轮之间设置有连接组件,连接组件可在一将转轴和太阳轮同步联接的第一位置和一将转轴和太阳轮相互断开的第二位置之间运动。本发明可对电机起到保护作用,简化了车桥的结构,减少了车桥的整体体积,有利于在车桥上布置较大功率的电机。
