In the industrial system, cars, as an important means of transportation, play an irreplaceable role in people's daily life. And a car with excellent performance and stable operation can not be separated from every precision design and manufacturing parts. As a technician who has been engaged in automobile repair and maintenance for a long time, I will start from my actual work and share some experience summary about key parts of automobile parts.
I. Engine related parts
1. Piston: The piston is one of the core moving parts in the engine, which directly participates in the energy conversion in the combustion process. Attention should be paid to check its wear and tear and whether there are cracks and other damage phenomena during maintenance.
2. Crankshaft: The crankshaft is responsible for converting linear reciprocating motion into rotary power and outputting it to the transmission. It is very important to check the bearing clearance and lubrication condition regularly to ensure its normal operation.
3. Connecting rod: an important component connecting the piston and the crankshaft, we should pay attention to the change of the hole size of the big end of the connecting rod to ensure the matching accuracy meets the requirements.
Second, the transmission system
1. Gearbox: Gearbox can realize power distribution at different speeds, which has a direct impact on vehicle running efficiency. Changing gear oil in time and regular cleaning and maintenance can effectively prolong the service life.
2. Drive axle: The drive axle undertakes the task of transmitting power to the wheels, so it is necessary to pay attention to the quality management and replacement cycle management of differential lubricating oil.
Third, the braking system
Brake disc/drum: As the main deceleration device, the brake disc or drum needs to be regularly checked for thickness reduction, and replaced in time if necessary to ensure driving safety.
Fourth, the suspension system
Spring and shock absorber: both of them work together to reduce the impact of road impact on the car body. In addition to the routine visual inspection, we should also judge whether there is abnormal noise or bumps through the test drive feeling.
Five, electrical equipment
Battery: keep the battery terminals clean and free from corrosion, and regularly check the electrolyte level and voltage value; At the same time, we should also pay attention to the moderate tension of the generator belt to prevent slippage from affecting the charging effect.
Six, cooling system
Radiator: Clean up the blockage to ensure smooth air circulation and avoid engine damage caused by high temperature. In addition, check the water pump for signs of water leakage and ensure that the antifreeze is within the appropriate proportion.
The above is only an overview of some important parts and their common problems. In the specific operation process, it is necessary to respond flexibly according to the characteristics of the vehicle type and personal experience. In a word, no matter which part, we need to pay enough attention and take scientific and reasonable measures to maintain it, so that the whole car can always be in the best condition.
