The invention belongs to the field of mechanical transmission, and relates to a single-motor double-pump motor parallel synchronous walking driving system. The device has the effects of large torque, low energy consumption and recovery of part of energy. According to the technical scheme, the device comprises a motor driving unit, a hydraulic motor driving unit and a planet wheel unit. The motor driving unit includes a first output shaft. The hydraulic motor drive unit includes a second output shaft. The planet wheel unit comprises a sun wheel, a planet wheel module and an outer ring. The sun gear is coaxially and fixedly connected with at least one first output shaft. The planet wheel module comprises a plurality of planet wheels, a planet wheel support and a straight gear, the planet wheels are meshed with the sun wheel and movably connected with the planet wheel support, the planet wheel support is fixedly connected with the straight gear, the center line of the straight gear and the center line of the sun wheel are collinear, and the straight gear is driven by the first output shaft. The outer ring is an inner gear and is arranged on the outer sides of the planet gears in a sleeving mode, the planet gears are further meshed with the outer ring, and the outer ring is fixed in the circumferential direction relative to the ground.
