Power matching method for electric tractor

Abstract

The invention discloses a power matching method for an electric tractor. A power output shaft transmission box, a second differential box, a rear transmission, a first driving motor, a front controller, a rear controller, a first differential box, a front axle transmission and a second driving motor are included. According to the power matching method of the electric tractor, the motor efficiencyduring working is high, the rotating speed range of an efficient area is wide, the transmissions with 1-3 gears can be adopted, a transmission system is simplified, meanwhile, the motor high-torque range is wide, the torque reserve coefficient is high, the start-up and acceleration properties are superior to the start-up and acceleration properties of a traditional internal combustion engine, compared with an ordinary fuel vehicle, the advantages of zero emission, low noise, easy operation and the like are further achieved, the power matching method is an optimal alternative scheme for solvingthe various problems confronted by the fuel vehicle, through arrangement of the power output shaft transmission box, power supply of a rear agricultural machine is convenient, through arrangement ofa PTO clutch, the power output shaft transmission box can be conveniently disconnected and connected, and some drawbacks of the internal combustion engine type tractor can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of electric tractor power systems, in particular to an electric tractor power matching method. Background technique [0002] In the field of agricultural machinery based on fuel oil, including tractors, the rapid development of agriculture has been affected by the supply of petroleum energy and its price. In the field of storage battery application technology, people have overlooked the importance of technical application in this field. At the same time, there are various disadvantages in the operation of fuel engines. First, traditional fuel tractors have low efficiency, narrow speed range in high-efficiency zone, and complex transmission system; Not good enough; in addition, traditional fuel tractors have high pollution emissions, high noise, and relatively difficult operation; according to such situation and background, the present invention provides a power matching method for electric tractors.
