The invention provides a double-motor-driven multi-planet-row power coupling device of an electric tractor. The combination of three planetary gear mechanisms and a synchronizer gear shifting mechanism is used as the power coupling device of a driving motor and a PTO motor. Particularly, various working modes including dual-motor independent driving, dual-motor coupling driving running and dual-motor coupling driving rotary tillage can be realized through left-right engagement and disengagement of the synchronizer and locking and unlocking of a first brake and a second brake. And the application of various operation working conditions such as low-speed light load, low-speed heavy load and high-speed transportation of the tractor is met. Therefore, the adaptability of the electric tractor to the environment is improved, and the utilization rate of the motor is increased.
Description
technical field [0001] The invention belongs to the technical field of electric tractors, and in particular relates to a multi-planetary power coupling device for electric tractors driven by double motors. Background technique [0002] In recent years, due to the shortage of oil resources and increasingly serious environmental pollution, the global battle for emission reduction, zero emission, and green environmental protection has begun, leading to an increasingly urgent demand for agricultural vehicles with low emissions, less pollution, and low noise in modern agricultural production. . To this end, countries have begun to formulate relevant standards and regulations to promote the research and development of new energy agricultural vehicles. Strengthen the concept of green development and expand the development requirements for the application of resource-saving and environment-friendly agricultural mechanization technologies. [0003] Compared with traditional tractor...
