Abstract

The invention relates to a dual-motor multi-mode driving system of an electric tractor and a control method thereof; the dual-motor multi-mode driving system comprises an electromagnetic clutch, an A motor, a B motor, an A switching motor, a PTO high-low gear switching motor, a differential speed lock switching motor, I-gear and II-gear shifting motors, III-gear and IV-gear shifting motors, a B switching motor and a differential speed lock. The electric tractor is driven by the A motor and the B motor; after switching gears, the two motors are meshed and driven by a gear for respectively providing power output and driving wheel power. According to different positions of the control switch in the driving system, the driving system is under different power driving modes. According to the working unit information given by a complete controller, the power driving mode of the driving system is determined. The system and the method can fully display the performance of the tractor power driving system based on the dual-motor, flexibly switch according to the working condition and the motor state, and reach the purpose of enhancing the cruising ability and high-efficient driving.

Description

technical field [0001] The invention relates to the field of agricultural machinery, and in particular provides an electric tractor dual-motor multi-mode drive system and a control method for electric tractors. Background technique [0002] Increasingly severe energy and environmental issues have prompted the development of transportation and agricultural equipment in an efficient, clean and sustainable direction. From the perspective of the development direction of new energy and the application of new technologies, agricultural equipment will gradually become electrified. At present, it will be wise for electric tractors to replace traditional internal combustion tractors for operations such as greenhouses and other occasions that require high precision, garden maintenance, lawn trimming, light-load farmland operations, and occasions that require high environmental pollution. The choice, and the noise generated by the pure electric tractor during operation is relatively sm...
