The invention relates to the technical field of planetary gear sets, and discloses an electric vehicle planetary gear set driving type axle which comprises a first-stage planetary gear set A, a second-stage planetary gear set B and an axle differential assembly C. The first-stage planetary gear set A and the second-stage planetary gear set B are fixedly connected through bolts. The second-stage planetary gear set B is fixedly connected with the axle differential assembly C through a bolt, the outer side of the first-stage planetary gear set A and the outer side of the second-stage planetary gear set B are connected in a meshed mode through a gear ring, and a hollow motor shaft is arranged in the center of the first-stage planetary gear set A and the center of the second-stage planetary gear set B. And the outer side of the hollow motor shaft is fixedly connected with a driving motor. Compared with an existing electric vehicle reduction gear set, the planetary gear set driving type axle of the electric vehicle has the advantages of being smaller in installation space requirement, highly integrated in equipment structure, light in weight, large in power torque, coaxial and concentric in input and output and the like.
