The invention discloses a four-gear new energy automobile hub motor driving device and a speed regulation method. The hub motor driving device comprises a motor, a shell, a first brake, a first-stage planetary gear train, a synchronizer, a second brake, a third brake, a fourth brake, a second-stage planetary gear train, a double clutch, a first shaft, a second shaft and a hub. The synchronizer is located in the rotation space of the special-shaped gear ring, the first shaft is an input shaft of the first-stage planetary gear train, and the second shaft is an input shaft of the second-stage planetary gear train. The second combined gear ring is connected with the special-shaped gear ring, and the first combined gear ring is connected with the first-stage planet carrier; through axial movement of the combination sleeve, the second shaft can be combined with the first-stage planet carrier or the special-shaped gear ring, the first-stage planet carrier and the special-shaped gear ring can transmit power to the second-stage sun gear, input of two rotating speeds of the second-stage sun gear is achieved, and through matching of two-stage input and two-stage output of the second-stage planet gear train, the four-gear speed regulation effect is achieved. According to the invention, the output torque can be increased, and more stable output power and speed regulation of more gears can be realized.
