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 (404) is connected to a hub (106). The hub (106) is connected to a spoke (110) and a rim (102, 111). The wheel support axle (104) passes through a rotor sleeve (209) and is provided with a hub bearing (107) to support the hub (106) and a whole wheel. A sun gear (401) disposed at an end of the rotor sleeve (209) of the internal-rotor hub motor is a power input of the planetary gear speed reducer, and the planetary carrier (404) is a power output. A planetary gear (402) 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. The brake system adopts a drum brake, and a brake drum (301) is connected to the rotor sleeve (209). A braking force is amplified by the planetary gear reducer, thereby reducing a braking force necessarily provided by the brake system, and the motor can provide an electric braking force in a process of braking.
