According to the system, two drive motor assemblies and two right-angle reducer assemblies are used. The two drive motor assemblies are distributed in the way of vertical and parallel separation of axes of the motors and a certain distance is left in the middle; the drive motor assemblies are installed by using a spherical hinge hanging method; and spherical joints of the drive motor assemblies can oscillate little at any direction to absorb air and thus move in a suspension mode. The input shafts of the two right-angle reducer assemblies are long spline shafts, wherein the spline shafts and the motor axes share the same axis; the spline shafts are respectively inserted into output spline holes of the two drive motor assemblies; and the output shafts can move up and down to absorb air and thus move up and down in a suspension mode. The right-angle reducer assemblies are one pair of right-angle transmission gear wheels having a certain speed ration; the output shafts and a vehicle wheel assembly share the same axis; an output shaft central axis direction of a driven gear wheel is a splined hole; one end of a jack shaft is inserted into the splined hole of the driven gear wheel to realize torque transmission; and a flange plate at the other end of the jack shaft is fixedly connected with a flange plate installed at a hub of the vehicle wheel assembly; and the hub and the vehicle wheel assembly are linked, thereby realizing driving of the vehicle wheel assembly.
