The invention relates to a wheel edge driving device. The wheel edge driving device comprises a driving motor; the speed reducer comprises a rotating component which is in transmission connection with the driving motor; the output shaft is in transmission connection with the speed reducer; the parking locking mechanism is used for locking rotation of the rotating component, the parking locking mechanism comprises a plug pin, a plurality of locking holes extending in the axial direction of a rotating shaft of the rotating component are formed in the rotating component in the circumferential direction, and the plug pin can move in the axial direction so as to be inserted into or separated from the locking holes. Parking locking of the wheel edge driving device is achieved. The plug pin is inserted into the locking hole of the rotating component in the axial direction, and compared with the mode that the periphery of the rotating component is clamped with the rotating component, the whole parking locking mechanism can be more compact, the space in the axial direction can be fully utilized, extra space in the speed reducer is not occupied, and the wheel edge driving device tends to be miniaturized so as to adapt to a small mobile chassis.
