Abstract

The invention discloses a double-motor coupling driving electric tractor and a control method thereof. The tractor comprises a storage battery pack 1, a battery management system 2, a whole vehicle controller 3, a coordinating controller 4, a main motor controller 5, a main motor 6, an auxiliary motor controller 7, an auxiliary motor 8, a power coupling gearbox 9, a differential mechanism 10, a power output shaft 11, driving wheels 12, a steering wheel 13 and a frame 14, wherein the main motor 6 and the auxiliary motor 8 are arranged at the input end of the power coupling gearbox 9, the outputend of the power coupling gearbox 9 has two paths of power output, and one path of power is output to the differential mechanism 10 and then transmitted to the two driving wheels 12 to drive the electric tractor to run; the other path of power is output to the power output shaft 11 to drive the electric tractor PTO to work. The electric tractor can achieve zero-pollution discharge and meet the power requirements of different operation loads under different working conditions, the working efficiency of a driving system is improved, and the cruising ability is enhanced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an electric tractor, in particular to an electric tractor driven by a double-motor coupling and a control method thereof. Background technique [0002] At present, the overall diesel utilization efficiency of China's agricultural machinery is still very low. With the implementation of large-scale agriculture and the improvement of the mechanization level of crops, the development of agricultural machinery has shown the characteristics of large-scale, multi-functional and comprehensive, so the increasing energy consumption will be cause more pollution. From the perspective of the development direction of new energy and the application fields of new technologies, electric power agricultural machinery equipment has become an important way for the further development of agricultural mechanization, and efficient, intelligent and environmentally friendly agri...
