Abstract: 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.
