The invention discloses a coaxial planet row driving device for a vehicle. The coaxial planet row driving device comprises a shell, a power motor, a planetary reducer gear mechanism and a planet row differential mechanism. The power motor comprises a rotor assembly, a stator assembly and a rotor shaft; the planetary reducer gear mechanism comprises a first sun gear connected with the rotor shaft, a first planet carrier and a gear ring which are arranged in the shell, and a first duplex planetary gear set arranged on the first planet carrier; the rotor shaft, the planetary reducer gear mechanism and the planet row differential mechanism are coaxially arranged, a first output part and a second output part at the two ends of the rotor shaft are connected to the driving wheel, and the first sun wheel is in meshed connection with the first duplex planetary gear set. By designing the planetary reducer gear mechanism with coaxial input and output and the planetary row differential mechanism with parallel axis design, the axial and radial sizes of the driving device are shortened to the maximum extent on the basis of ensuring the gear performance, the miniaturization and light weight of the driving device are facilitated, and the applicability is greatly improved.
