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.
