| description | The invention discloses a direct-drive type high-response axial plunger type variable hydraulic motor with a servo motor. The variable displacement mechanism of the direct-drive type high-response axial plunger type variable hydraulic motor comprises a servo motor, a variable control lever, a displacement sensor and a servo driving controller, wherein the output end of the servo driving controller is connected with the servo motor, and a rotor of the servo motor is fixedly connected with one end of the variable control lever; the other end of the variable control lever is positioned in a sliding groove of the displacement sensor, and the variable control lever can move to and fro in the sliding groove; and the end part of a driver pin of an oil distribution disc of the hydraulic variable displacement motor is fixedly connected with the variable control lever, and the displacement sensor is connected with a first signal feedback end of the servo driving controller. The variable hydraulic motor is simple and reasonable in structure, variable displacement and high frequency response and high precision stepless adjustment of variable torque output are realized on the axial plunger type variable hydraulic motor, and the whole adjustment process is smooth and is free of vibration. |
