The invention discloses a planetary speed reduction transmission electric driving wheel which comprises a planetary speed reducer, a direct-current motor, a planetary speed reduction inner gear shell and a rubber tire. The direct-current motor is directly installed on a second-stage planet carrier of the planetary speed reducer, the planetary speed reducer comprises a first-stage planet carrier, three first-stage planet gears, a first-stage sun gear, a second-stage planet carrier, a second-stage sun gear and a planetary reduction inner gear shell. Power of the direct-current motor is converted into low-speed large-torque power through an outer meshing-inner meshing planetary reduction transmission chain, and the low-speed large-torque power is output to the rubber tire. According to the planetary speed reduction transmission electric driving wheel, the high-speed stage of the planetary speed reducer adopts a planetary transmission floating technology, uniform load distribution of a high-speed stage planetary transmission planetary gear is achieved, and transmission noise is reduced; and due to the adoption of a planetary transmission mode, use of a duplicate gear is avoided, the manufacturing precision of the gear is improved, the manufacturing cost is reduced, and the planetary speed reduction transmission electric driving wheel is more suitable for mass production.
