Description
Technical Field
The invention relates to the technical field of tractors, in particular to an electric unmanned intelligent tractor.
Background
The wheel type farm tractor is a very important mechanical device in the agricultural mechanized production process, although it is a relatively complex machine, its type and size are different, but they are all composed of three major parts of engine, chassis and electric equipment. The liquid or gas fuel and air are mixed by internal combustion engine and then fed into the interior of machine to produce heat energy, then converted into mechanical energy. However, the internal combustion engine of the tractor generally uses petroleum fuel, and the exhaust gas discharged therefrom has a high content of harmful gases. The piston reciprocating in the cylinder is hinged to one end of the connecting rod via piston pin, and the other end of the connecting rod is connected to the crankshaft to constitute the crank-link mechanism. As the piston reciprocates within the cylinder, the connecting rod forces the crankshaft to rotate, or vice versa. The power of the cylinder makes the driving wheel obtain driving torque force through the transmission system, the driving wheel obtaining driving torque gives the horizontal force (tangent force) backwards to the ground through the tyre pattern and the tyre surface, and the ground has the same horizontal reaction force with the driving force and the opposite direction, and the reaction force is the driving force for pushing the tractor to run forwards. When the driving force is enough to overcome the forward rolling resistance of the front and rear wheels and the traction resistance of the attached farm implement, the tractor runs forward. If the driving wheel is supported off the ground, namely the driving force is equal to zero, the driving wheel can only idle in situ, and the tractor cannot run; if the sum of the rolling resistance and the traction resistance is larger than the driving force, the tractor cannot run. It can be seen that the running of the wheeled tractor is achieved by the interaction of the driving torque driving wheels and the ground, and the driving force is larger than the sum of the rolling resistance and the traction resistance. Therefore, the structure and the principle of a power transmission system of the internal combustion engine are complex relative to a motor transmission system, the power transmission system is easy to damage, more and complex in maintenance parts, simple in structure, high in efficiency and very convenient to disassemble and maintain. After the petroleum fuel used by the internal combustion engine is combusted, a large amount of harmful gas is emitted, and the environment and crops are polluted. The motor and the motor are in electric transmission, and zero emission can not cause pollution to the environment and crops.
