Engine accessories

The engine is the "heart" of a tractor, and its accessories include:

Cylinder block and cylinder liner: The basic components that make up the engine, responsible for accommodating the piston and forming the combustion chamber.
Piston and piston ring: The piston moves back and forth in the cylinder, converting thermal energy into mechanical energy through the connecting rod and crankshaft; The piston ring ensures the sealing between the cylinder and the piston, preventing gas leakage.
Crankshaft and connecting rod: convert the reciprocating motion of the piston into rotational power to drive the tractor forward.
Cylinder head and intake/exhaust valves: The cylinder head is equipped with a cooling water jacket and intake/exhaust valves, which are responsible for controlling the inflow and outflow of gases and the sealing of the combustion chamber.
Oil pump and oil filter: The oil pump is responsible for delivering lubricating oil to various friction surfaces to reduce wear; The oil filter filters out impurities in the engine oil and keeps it clean.

Transmission system accessories

The transmission system is responsible for transmitting the power of the engine to the driving wheels, achieving the driving and operational functions of the tractor. The main accessories include:

Clutch: Used to connect or disconnect the power transmission between the engine and gearbox, achieving smooth starting and shifting.
Gearbox: By changing the meshing relationship of gears, the tractor's driving speed and traction force can be adjusted to meet different operational needs.
Drive shaft and universal joint: transmit the power of the gearbox to the drive axle to achieve the driving of the tractor.
Differential: allows the driving wheels to rotate at different speeds, ensuring the stability of the tractor when turning.

Hydraulic system accessories

Hydraulic systems are used to generate pressure and transfer energy, driving agricultural tools to obtain power. The main accessories include:

Hydraulic pump: converts mechanical energy into hydraulic energy to provide power for hydraulic systems.
Hydraulic cylinder: Convert hydraulic energy into mechanical energy, achieve linear reciprocating motion, and drive agricultural tools for operation.
Distributor: controls the flow direction and flow rate of hydraulic oil to achieve various functions of the hydraulic system.
Hydraulic oil pipe and joint: Connect hydraulic components and transmit hydraulic oil.

Electrical system accessories

The electrical system is responsible for functions such as starting, lighting, and signal transmission of the tractor. The main accessories include:

Battery: stores electrical energy and provides power for the tractor's electrical system.
Generator and regulator: The generator is responsible for converting mechanical energy into electrical energy and charging the battery; The regulator controls the output voltage of the generator to ensure stable operation of the electrical system.
Starter: Used to start the engine and convert electrical energy into mechanical energy.
Instruments and sensors: display the operating status of the tractor, such as speed, oil pressure, water temperature, etc., to help the driver timely understand the working condition of the tractor.

Walking system accessories

The walking system is responsible for supporting the weight of the tractor and transmitting power to the ground, enabling the tractor to travel. The main accessories include:

Tire and wheel rim: The tire comes into contact with the ground, providing traction; The wheel rim supports the tire and transmits power.
Drive axle: includes components such as differential and half shaft, which transmit the power of the gearbox to the drive wheels.Suspension system: connects tractor and agricultural tools, transmits traction and buffers vibration, improving stability and comfort during operation.

Other accessories

In addition to the main accessories mentioned above, the tractor also includes many other accessories, such as:

Air filter: Filters the air entering the engine, preventing dust and impurities from entering the cylinder and protecting the engine.
Fuel filter: Filters impurities and moisture from the fuel to ensure cleanliness and normal engine operation.
Cooling system accessories: including radiator, water pump, fan, etc., responsible for engine cooling and preventing engine overheating.
Lubrication system accessories: including oil dipstick, oil filling port, etc., convenient for the driver to check and add lubricating oil.
