The invention discloses a tractor electric suspension lifting system and a control method thereof. The suspension lifting system includes a mechanical structure part and an electrical control part; the mechanical structure part includes a lifting device, and the lifting device includes a driving motor, a reducer and a wire A rod and nut mechanism; a bracket is fixedly arranged on the vehicle frame, and a rotating base is fixedly connected to the bracket, and the lead screw is arranged inside a bearing provided inside the rotating base. The electrical control part includes a controller, a driver, a motor, a GPS speedometer and a wheel speed sensor. The controller is connected to the driver, the driver is connected to the motor, the GPS speedometer is installed on the frame, and the wheel speed sensor is installed on the driving wheel; the wheel speed sensor and The GPS speedometer communicates with the controller through the CAN bus. The invention has the functions of resistance adjustment and position adjustment. The resistance adjustment is realized by adding a GPS speedometer and a wheel speed sensor to detect the slip rate, and the position adjustment is realized by the precise rotation of the stepping motor and the geometric relationship of the lifting mechanism.
Description
technical field [0001] The invention relates to the field of agricultural machinery, in particular to a tractor electric suspension lifting system and a control method thereof. Background technique [0002] The automation and energy saving of agricultural machinery is a modern development trend. In recent years, the development of intelligent control technology and advanced machinery manufacturing technology have brought new technological changes to agricultural machinery and promoted the development of agricultural machinery in the direction of intelligence and automation.
