The invention provides an electric variable-speed hub. The rotor of the motor is a spline housing and can be an inner rotor and an outer rotor. The spline housing is in sliding connection with a first spline section of a spline shaft in the gear shifting device and rotates simultaneously. And a second section of spline of the spline shaft is connected with the gear planetary transmission. A stator of the motor and the gear planetary transmission are installed on an axle connecting hub through bolts, and the brake disc and the hub are installed on a power output disc of the gear planetary transmission through bolts. A push rod of the gear shifting device pushes a spline shaft to move in a motor rotor spline sleeve and a spline sleeve in the center of a sun gear of the gear planetary transmission, and a second section spline of the spline shaft is combined with sun gears of different stages of gear planetary transmission mechanisms so that different rotating speeds and torques can be transmitted to a hub through a power output flange. The requirements of low speed and large torque of the driving wheel when the tractor for agriculture and forestry and the special driving chassis work in the field and forest land are met.

    本发明提供一种电动变速轮毂。电动机的转子为花键套,可以是内转子和外转子。花键套与换挡装置中的花键轴第一段花键滑动连接同时转动。花键轴的第二段花键与所述齿轮行星传动变速器连接。电动机的定子和齿轮行星传动变速器通过螺栓安装在车桥连接毂上,制动盘和轮毂通过螺栓安装在齿轮行星传动变速器的动力输出盘上。换档装置的推杆推动花键轴在电动机转子花键套内和齿轮行星传动变速器太阳轮中心的花键套内移动,花键轴的第二段花键与不同级齿轮行星传动机构的太阳轮结合便有不同的转速和扭矩通过动力输出法兰传给轮毂,以满足农林用拖拉机和专用行驶底盘在田间、林地作业时要求驱动轮的低速和大扭矩。
