A wheel hub motor drive system is provided comprising a knuckle (1), a drive mechanism (2), a wheel bearing (3) and a brake system (4). In the axial direction (A) of an output shaft (24) of the driving mechanism (2), the driving mechanism (2) is located on one side of the steering knuckle (1), and the wheel bearing (3) and the braking system (4) are located on the other side of the steering knuckle (1). An outer ring (32) of the wheel bearing (3) is detachably installed on the steering knuckle (1), an inner ring (31) of the wheel bearing (3) is in transmission connection with the output shaft (24) through a spline, and a brake caliper mechanism of the brake system (4) is detachably installed on the installation portion (11). According to the structural design, the steering knuckle and other structures of the hub motor driving system can be conveniently matched with different braking systems and wheel bearings, and dismounting and mounting of the steering knuckle and other structures of the hub motor driving s
