The invention relates to the technical field of automobile transmission, in particular to a hub dual-motor driving device which comprises a hub, a tire, motors, a planetary gear mechanism and an output shaft, the tire is connected with the output shaft through the hub, the motors comprise the first motor and the second motor, stators of the first motor and the second motor are both fixedly arranged in a shell, and the planetary gear mechanism is arranged in the shell. A rotor of the first motor is connected with the output shaft through a planetary gear mechanism, a rotor of the second motor is connected with a sun wheel hollow shaft of the planetary gear mechanism through a supporting frame, and brake clutches are arranged between the rotor of the first motor and the shell and between the rotor of the second motor and the shell respectively. The two brake clutches are matched with the planetary gear mechanism and the double-motor drive hub, energy recovery and brake speed reduction capacity of different degrees can be achieved, driving power of different speed ratios is achieved, the structure is simple, cost is low, and integrated matching of a vehicle transmission system is facilitated.
