The invention discloses a loader walking hydrostatic and mechanical hybrid driving system, which belongs to the field of engineering machinery and comprises a machine body. A hydraulic system is mounted on the machine body. The hydraulic system comprises a hydraulic driving walking system and an oil tank; the mechanical system comprises a loader mechanical driving walking system; an engine and a transfer case are mounted on the machine body; the engine is connected with the transfer case, the transfer case is connected with a variable hydraulic pump, the variable hydraulic pump is connected with an oil inlet of a three-position three-way electromagnetic valve, one path of an oil outlet of the three-position three-way electromagnetic valve is connected with a hydraulic motor and the motor is driven to drive a load, and the other path enters an energy accumulator through the three-position three-way electromagnetic valve to store energy. The hydraulic motor is connected with the planetary gear set, torque is transmitted to the speed reducer after being converted by the motor through the gear set, and then an output shaft of the speed reducer drives the loader to walk. The actual usetime of the hydraulic torque converter is shortened, so that the energy utilization efficiency of the system is improved, and the braking energy of the hydraulic system recovery loader is improved.
