A low-floor electric axle assembly including: an axle housing (11), hub motors, planetary gear reducers, hubs (17), a brake system, C-shaped beams (19), and a suspension system. Mechanical mounting of the suspension system is compatible with a conventional axle, and arrangement manners of the brake system, the hub motors, and the planetary gear reducers are capable of expanding a width of a coach aisle. Each of the hub motors is arranged coaxially with a rim (18); a first-stage cylindrical gear drive, bevel gear drive, or hypoid gear drive is removed; an unconventional-structure planetary gear reducer is provided to ensure a high transmission ratio and transmission efficiency; the brake system is arranged at two ends of the axle and at inner sides of the motors, thereby making full use of space at the two ends of the axle, and forming the low-floor electric axle assembly.
