Abstract

This invention relates to the field of walking motor technology, and particularly to a walking motor control system and mechanical device, comprising: a first control valve, a second control valve, a drive assembly, an oil inlet pipe, an oil drain pipe, and a motor body. The drive assembly is used to control the displacement of the motor body. The drive assembly includes a first piston chamber, a second piston chamber, a servo piston, a regulating piston, a first auxiliary oil inlet pipe, and a second auxiliary oil inlet pipe. The servo piston is disposed in the first piston chamber, and the regulating piston is disposed in the second piston chamber. The second piston chamber is larger than the first piston chamber, and the regulating piston is larger than the servo piston. The first piston chamber and the second piston chamber are connected, thereby enabling the servo piston to drive the motor body to obtain a larger displacement, thereby driving the brake to obtain a larger torque and ensuring that the mechanical device does not experience a lack of walking power.
