Abstract

The invention relates to the technical field of tractors, and discloses a series-parallel hybrid power tractor power system and a tractor. An output shaft of the engine is in transmission connection with the generator through a main shaft of the transfer case, the generator is connected with the motor through the electric control clutch, the generator and the motor are both electrically connected with the electric coupling device, and the electric coupling device is electrically connected with the electric energy storage device. The motor is in transmission connection with the AMT gearbox, and the AMT gearbox is in transmission connection with the wheels through the rear axle; an output shaft of the transfer case is connected with a power output device PTO through a rear axle; and the main shaft of the transfer case is in meshing transmission connection with the output shaft. Different power driving modes can be provided under different working conditions, the power economy of the tractor is improved, and pollutant emission is reduced; power transmission lines of the walking transmission mechanism and the power output device are mutually independent and do not interfere with each other; the power system is simple in structure, does not need a complex gearbox, occupies a small space, and facilitates arrangement of the whole vehicle.

Description

technical field [0001] The invention relates to the technical field of tractors, in particular to a power system of a series hybrid tractor and the tractor. Background technique [0002] Tractors are the main power machinery in agricultural production. At present, tractors in my country generally use fuel engines as power sources. This kind of traditional tractor has low traction efficiency, high energy consumption, and large exhaust particulate matter emissions, which seriously pollute the environment. Compared with pure electric tractors, although they have the advantages of low emission and no pollution, the technology is still immature and there are shortcomings such as insufficient battery life. Hybrid tractors can solve the above-mentioned problems existing in traditional tractors and pure electric tractors. [0003] The hybrid system is divided into series hybrid system, parallel hybrid system and hybrid hybrid system, among which the hybrid power system combines th...
