摘要： Disclosed are an electric wheel assembly applicable for a parallelly mounted dual-tire wheel, an axle, and a vehicle. The electric wheel assembly includes a wheel and support axle assembly, an internal-rotor hub motor, a planetary gear reducer and a brake system. A planetary carrier is connected to a hub. The hub is connected to a spoke and a rim. The wheel support axle passes through a rotor sleeve and is provided with a hub bearing to support the hub and a whole wheel. A sun gear disposed at an end of the rotor sleeve of the internal-rotor hub motor is a power input of the planetary gear speed reducer, and the planetary carrier is a power output. A planetary gear of the planetary gear reducer is a tower-shaped gear and realizes a relatively high transmission ratio under a condition that an axial length is relatively small.

摘要： A low-floor electric axle assembly including: an axle housing, two hub motors, two planetary gear reducers, two hubs, a brake system, two C-shaped beams, and a suspension system. Mechanical mounting of the suspension system is compatible with a conventional axle. The axle housing has a left and right symmetrical dumbbell-shaped structure configured to bear a weight of a vehicle. The hub motors are inner rotor type motors and are separately arranged at two ends of the axle housing left and right symmetrically. The hub motors are arranged coaxially with two wheels respectively. Two hub motor rotors are connected to the planetary gear reducers respectively. Each of the planetary gear reducers is a single-stage planetary gear reducer. A sun gear of each of the planetary gear reducers receives power outputted by each of the hub motor. Two planetary gear reducer housings are power output ends connected to two rims respectively.
