Abstract

The present application relates to the technical field of construction machinery and discloses a hydraulic walking system, a control method for the hydraulic walking system, and a static hydraulic loader. The system includes a piston pump, a front axle motor, a rear axle motor, and a flow dividing and converging valve. The piston pump is configured to drive forward or reverse movement based on hydraulic oil. The flow dividing and converging valve is connected to the piston pump, and is configured to adjust the flow direction of the hydraulic oil, enabling the hydraulic oil to flow into the front axle motor and the rear axle motor in a parallel-connection or series-connection form. The front axle motor and the rear axle motor are connected to the flow dividing and converging valve, and are configured to convert hydraulic energy of the hydraulic oil into mechanical energy. The present application enables the forward and reverse movement of the hydraulic walking system, and the series and parallel connection of the motors, wherein the flow direction of the hydraulic oil can be flexibly adjusted, thereby providing different walking speeds and traction forces, and ensuring the normal operation of a small-type static hydraulic loader under various working conditions.
