Abstract

The invention discloses an electric suspension and lifting system for a tractor and a control method thereof. The suspension and lifting system comprises a mechanical structure part and an electricalcontrol part; the mechanical structure part comprises a lifting device, and the lifting device comprises a driving motor, a speed reducer and a lead screw nut mechanism; a support is fixedly arrangedon a frame, a rotation base is fixedly connected to the support, and a lead screw is arranged in a bearing in the rotation base. The electrical control part comprises a controller, a driver, a motor,a GPS velometer and a wheel speed sensor, the controller is connected with the driver, the driver is connected with the motor, the GPS velometer is arranged on the frame, and the wheel speed sensor isarranged on a driving wheel; the wheel speed sensor and the GPS velometer are in communication with the controller through CAN buses. According to the electric suspension and lifting system for the tractor, the functions of resistance adjustment and position adjustment are achieved, resistance adjustment is achieved by additionally arranging the GPS velometer and the wheel speed sensor for detecting the sliding rotation rate, and position adjustment is achieved through precise rotation of the stepping motor and a geometrical relationship of a lifting structure.

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. As an important agricultural machinery, tractors are also developing towards automation and intelligence in modern times. Realizing the electrification of each subsystem of the tractor is an effective way to make the tractor intelligent. [0003] The tractor hitch is an important device for the tractor to connect and pull agricultural implements. Its main function is to control the raising and lowering...
