Abstract
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.
