What are the mechanical accessories of the card.
Caterpillar is one of the world's leading manufacturers of construction machinery and its products are used in a wide range of engineering applications. In order to maintain the good performance of the equipment and prolong its service life, it is very important to regularly replace and repair the parts of construction machinery. This article will introduce the main accessories and their functions of the truck machine.
1. Engine parts.
The engine is the core component of construction machinery, so its accessories are crucial. The common ones mainly include:
1.Air filter: Used to filter the air entering the engine and prevent impurities and dust from entering.
2.Oil filter: Used to filter engine oil and prevent impurities and dirt from entering the engine.
3.Diesel filter: used to filter diesel fuel and ensure the cleanliness of the fuel.
4.Coolant filter: Used to filter coolant and prevent impurities and dirt from entering the heat dissipation system.
5.Spark plug: used to generate an electric spark and ignite the combustible mixture in the gas cylinder.
6.Injector: Used to inject fuel into the cylinder and cooperate with the spark plug to achieve the ignition of the combustible mixture.
7.Cylinder head: It is used to close the cylinder and provide it with a proper combustion environment.
8.Piston rings: used to seal cylinders and prevent gas leakage.
2. Transmission system accessories.
The transmission system is an important part of construction machinery, and its main accessories include:
1.Gearbox: used to change the speed and torque of the engine to meet different working needs.
2.Clutch: Used to connect or disconnect the power transmission between the engine and the drivetrain.
3.Transmission shaft: used to transmit power so that the machine can run normally.
4.Reducer: It is used to reduce the speed and increase the torque to meet the specific work needs.
5.Power take-off: Used to take power from the transmission system to drive other equipment or devices.
6.Transfer case: It is used to distribute power to multiple output shafts to realize the multi-functional operation of the machine.
7.Differential: It is used to realize the differential speed of the left and right wheels and improve the steering performance and passing performance of the machine.
8.Final reducer: used to further reduce the speed and increase the torque to meet the needs of walking and operation.
9.Chains and sprockets: used to transmit power and ensure the normal operation of machinery.
10.Belts and timing belts: used to transmit power and reduce noise and vibration.
3. Hydraulic system accessories.
Hydraulic system is one of the important driving methods of construction machinery, and its main accessories include:
1.Hydraulic Tank: Stores hydraulic oil to supply the hydraulic system with the required fluid.
2.Hydraulic pump: converts the power of the engine into the pressure of the hydraulic oil and drives the hydraulic system to work.
3.Hydraulic motor: converts the pressure of hydraulic oil into mechanical energy to drive machinery to run.
4.Hydraulic valve: control the flow direction, flow and pressure of hydraulic oil, and realize the adjustment and control of various actions.
5.Oil pipes and fittings: used to connect hydraulic components to ensure the normal flow of hydraulic oil.
6.Seals and oil seals: used to seal the joint surface and oil port of hydraulic components to prevent oil leakage.
7.Oil Filter: Used to filter impurities and dirt in hydraulic oil and maintain the cleanliness of the oil.
8.Pressure gauges and sensors: Used to monitor the pressure and flow of the hydraulic system and provide the necessary feedback to the operator.
9.Oil cooler: It is used to reduce the temperature of the hydraulic oil and maintain its normal working performance.
10.Accumulator: Used to store hydraulic energy and release it when needed to achieve a specific action or to compensate for leakage.
Fourth, chassis and walking system accessories.
The chassis and walking system are the basic support and moving parts of construction machinery, and its main accessories include:
1.Frame and underframe: As the basic structure of construction machinery, it carries various components and equipment.
