The car chassis carries many important assemblies of the car, including transmission, braking, and steering. It is an important support for the car structure and accepts engine power to ensure the normal driving of the car. Its importance is self-evident. However, the chassis does not have a smooth and beautiful appearance of the body, nor can it directly provide a comfortable riding environment like a seat, and there are very few opportunities for direct contact with the owner, which is often ignored by the owner.
The car is rotten before the bottom.
There is a saying in the industry that "a car is bad before the bottom". The car chassis can reflect the "life" of a car to a certain extent: use, maintenance, etc. In the used car market, the condition of the car chassis is one of the most intuitive criteria for the owner to judge the quality of the vehicle.
Regarding "the car is rotten before the bottom", Master Xiong of a 4S store said that the first is the influence of road conditions. In addition to the tires, the chassis is the closest part of the car to the road. Generally, the minimum ground clearance of a family car is about 110~170mm. The chassis close to the road has to withstand the test from various road conditions. Complex road conditions are easy to cause damage to the chassis, such as water, sand and gravel on the road. "Accumulated water, especially rainwater, is acidic, and it will corrode the chassis if it is not cleaned in time; sand and gravel splashed during the driving of the vehicle will hit the chassis, damage the protective layer on the surface, and cause corrosion".
Another reason is the neglect of car owners. Under normal circumstances, there are very few opportunities for car owners to have direct contact with the chassis, and it is unrealistic to check the chassis by themselves. As a result, some car owners lack the awareness of taking the initiative to maintain the chassis. Generally, they will only send them to the repair shop for maintenance when problems are found, and the chassis cannot be repaired. Maintenance.
Chassis problems easy to recruit losses
The automobile chassis carries many assemblies and components of the automobile, and it is also an important part of supporting the entire vehicle. Another technician, Master Hu, said that if there is a lack of maintenance, once the chassis parts rust and corrode, it will cause the structure of the vehicle to loosen, which will affect normal driving, and seriously cause traffic accidents, economic losses, and endanger life. safety.
The owner of the car, Mr. Wu, was on a business trip. When he passed one of the corners, the steering of the car suddenly failed and hit a tree on the side of the road. Fortunately, the speed was not fast at that time, so it did not cause serious consequences. The cause of the accident was the damage of the steering ball head.
Afterwards, Mr. Wu recalled that on the road, he found that the lower chassis of the engine felt loose and accompanied by abnormal noise, but the situation was slight at that time and did not affect normal driving, so he did not care. Mr. Wu said that the car in the accident is a means of transportation and is usually busy at work, so unless there is a problem, it is rarely submitted for inspection and maintenance.
Chassis maintenance needs attention
"Now the general new car chassis will have a protective film, but will slowly lose the effect of oxidation, so still need to rust treatment." When it comes to the maintenance of the chassis, Master Xiong and Master Hu both believe that rust prevention should be done well.
First of all, pay attention to cleaning the chassis. Especially in the rainy season, rainwater mixed with silt and other dirt is particularly harmful to the chassis. Carefully cleaning the chassis when washing the car can clean up the rainwater and dirt attached to the chassis in time to minimize the damage to the chassis.
"However, attention should be paid to selecting appropriate special cleaning agents, and do not use alkaline cleaning agents, washing powder, etc. to wash the body and chassis," Master Xiong reminded, "otherwise it will damage the protective film of the chassis, affect the anti-rust effect and shorten the anti-rust time."
Secondly, it is also very important to do daily maintenance. It is best to go to a professional repair shop regularly to check and maintain the chassis.
In addition, you should also pay attention to the daily driving. If you encounter complex road conditions, you can avoid them. If you need to pass, you must first observe clearly, try to avoid scraping the bottom and other situations, so as to minimize the impact of road conditions on the chassis. Chassis can also be sealed for vehicles, especially vehicles that have to pass through complex road conditions such as village roads and mountain roads. Enclosing plastic can play a very good protective effect on the chassis.
Master Hu reminded that because the chassis sealing plastic has very high professional requirements, the owner had better choose a regular service shop. (trainee reporter ouyang jinhong)
