The invention provides a coaxial driving device and a vehicle. The coaxial driving device comprises a shell supporting frame, a driving motor, a composite planet carrier, an NW planet row gear train and a differential gear train. Wherein the driving motor is mounted on the shell supporting frame; the compound planet carrier is rotationally mounted on the shell supporting frame; the NW planet row gear train is mounted on the compound planet carrier, a rotary center inner cavity is formed in the NW planet row gear train, and the NW planet row gear train is connected with the driving motor; the differential gear train is installed on the compound planet carrier and located in the rotary center cavity, and the outer diameter of the moving track of the differential gear train is larger than the inner diameter of the moving track of the NW planet row gear train; and the driving motor, the compound planet carrier, the NW planet row gear train and the differential gear train are coaxially arranged. The coaxial driving device is used for solving the problem that an existing coaxial driving device is large in radial size and axial size.
