The three major parts of the car, especially the chassis, so what do you need to pay attention to in

What is included in car chassis maintenance.

1. Check the condition of car tires frequently.

The first thing to do is to check the air pressure of the tires and make sure that they are within the normal range at all times. If you often drive in bad road conditions, you should always check the tire tread pattern for sharp nails, stones and broken glass to avoid puncturing the tire.

In addition, after driving a certain mileage, the front and rear tires should be replaced, and according to the manufacturer's regulations, after driving to a certain mileage, the front and rear tires should be exchanged with each other. Because the load weight of the two is not equal, the wear is also unequal, so that the best use can be used to extend the service life of the tire.

2. Clean and scrub the chassis of the car regularly.

The automobile chassis is the closest part of the automobile parts to the ground, and in the process of driving, it often falls into the mud and sand, causing the automobile chassis to be stained with mud, garbage and other attachments. These pollutants will enter the chassis of the car, causing the pollution of the transmission system and other components of the car chassis, causing the friction between the parts to increase, accelerating the loss of parts, greatly shortening the service life of the car, and in rainy and snowy weather, the components in the rain and snow may corrode the parts of the chassis to a certain extent.

Therefore, we need to wash the chassis of the car regularly, and thoroughly clean the chassis frame, steering arm, steering tie rod, rotating shaft, tire fender and other positions after rain and snow to prevent the above parts from rusting.

3. Check the operation of each part of the vehicle chassis.

In the normal daily driving process of the vehicle, there will be no abnormal noise, and when there is a problem with the automobile chassis, there will be a more abnormal and huge sound, and the operation and control of the automobile will also be inconvenient at this time, for this reason, the operation of the above-mentioned parts needs to be analyzed in the process of driving the car, and the problem is found to be repaired in time to the maintenance plant.

The chassis of the car generally needs to be made of chassis armor, which can effectively prevent rust and the jumping of stones on the road, and also has a protective effect on the slight drag bottom.

The maintenance of the automobile chassis is mainly to carry out daily cleaning of the chassis, regular maintenance of the chassis shock absorption system and steering system, and maintenance and treatment of the rust of the car chassis.

The maintenance of automobile chassis is often regarded as dispensable, far less important than the engine and body, in fact, whether the automobile chassis is maintained properly, directly related to the safety, handling, comfort and economy of the car and other key performance, can not be taken lightly.

Automobile chassis maintenance is mainly cleaning and inspection, checking whether there is leakage and defect, whether there is deformation. There is a new car to make a chassis armor.

<> "Automobile chassis maintenance can not be ignored.

When it comes to car maintenance, the first reaction should be the engine, tires, brake system, etc., while car chassis maintenance is easy to be overlooked. It is important to know that the chassis of a car is directly related to the handling, comfort, and safety of the car. The importance is self-evident, so its maintenance should also be taken seriously!

1.Clean the chassis regularly.

Wash the chassis of the car regularly, and thoroughly clean the chassis frame, steering arm, steering tie rod, rotating axle and tire fender after rain and snow to prevent corrosion of parts. Be careful not to use alkaline detergents to clean the body and chassis during daily car washing, otherwise it will affect the anti-rust effect and shorten the anti-rust time.

2.Chassis armor.

The so-called chassis armor is to coat the chassis of the car with a layer of special elastic colloidal material, which can completely wrap the chassis of the car and become a special protective layer of the car chassis after curing. It can not only prevent the rust of the chassis, but also reduce the wear and tear of the chassis when it is hit by sand and gravel.

3.Check the condition of each part of the chassis.

In the process of daily driving, the vehicle generally does not produce abnormal noise, but when there is a problem with the chassis of the car, there will be obvious abnormal noise, and then the operation and control of the car will also be abnormal. For this reason, it is necessary to analyze the operation of the components during the driving of the car, and find problems in time to the repair shop for inspection and maintenance.

The chassis of the car is an important part to ensure the overall performance of the car, and whether the rubber is well maintained will affect the handling and comfort of the car. Therefore, we must pay more attention to the operation status of the car chassis, remember to clean and maintain it regularly, and once an abnormality is found, it should be sent to a professional institution for maintenance in time.

The chassis maintenance of the car is very important!

The car chassis inspection includes:1Whether the four-wheel shock absorber is leaking, 2

Brake pad thickness, 3The tie rods and rubber sleeves supporting the wheels are trapped in the town of Hu whether they are damaged and deformed, 4Tire wear (check the wheel alignment data if necessary), 5

Whether the steel rim is deformed, 6Whether there is an abnormal sound in the wheel bearing, 7The torque of the tire screw is enough for the trip, 8

Is the tire pressure sufficient, 9Whether the exhaust pipe and hanging feet are damaged, 10Whether there is oil leakage at the bottom of the engine and gearbox, 11

Whether there are scratches on the body while driving, 12Whether the steering ball head and swing arm ball head are loose, 13Whether the drive shaft is leaking oil.

After the above inspection, it is ensured that the car will not lose control of the vehicle direction, abnormal braking, vehicle deviation, abnormal tire wear and other phenomena that affect safe driving when driving on the road.

1) Clean regularly.

Rain and snow weather often have sediment, water stains on the chassis, in the north of the skin side even a lot of roads will be sprinkled snow melting agent to remove the ice and snow on the road, they are not only difficult to wash, but also have a strong corrosion of the vehicle chassis, for a long time, the chassis is easy to be eroded and rusted. Therefore, the first step in the maintenance of the chassis is to keep the chassis of the vehicle clean on a regular basis.

2) Chassis armor.

The chassis armor can dampen vibration and sound insulation and improve driving comfort. A large part of the noise of the car comes from the road noise and the sound of sand and gravel knocking, and the high elasticity of the chassis armor can effectively absorb and reduce these noises, and also reduce the noise caused by the vibration of the chassis steel plate, so as to achieve the purpose of noise reduction. Most importantly, this flexible material can greatly reduce the damage to the chassis caused by road surface rigidity.

3) Protective plate.

For drivers who often walk on the road in poor conditions, it is not enough to rely on chassis sealing, and you can consider installing chassis protection plates.

4) Regular maintenance.

The maintenance of the old vehicle is "three points of repair, seven points of maintenance", not all of them need to be replaced, but should be carefully taken care of bit by bit.

Chassis maintenance: 1. Protect the chassis; 2. Ensure driving safety; 3. Improve comfort; Fourth, the value of the vehicle preservation;

Chassis rust prevention is divided into six steps:

Step 1: Raise the car, rinse the chassis with a high-pressure water gun, first apply the engine exterior cleaner or engine degreaser, remove the oil sludge and sand bonded on the chassis, or use special sandpaper to polish off the original anti-rust layer.

Step 2: Use a water blowgun to blow out the water in the gap and dry the water with a towel.

Step 3: When preparing to spray the anti-rust treatment layer, you must first cover the tires and exhaust pipes with masking paper (mostly newspapers) and tape, especially the sensors and shock absorbers on the car body.

Step 4: Spray the chassis anti-rust material to the chassis in turn, spray at least 3 layers, with a thickness of about 3 mm (the national operating standard is 4 to 5 layers of material).

Step 5: Partial repair of the coating to ensure that the greater the opacity, the better.

Step 6: Remove the surrounding masking and wash the non-sprayed parts of the perimeter with a special detergent and wait for air to dry, about 4 to 5 hours. According to reports, the entire chassis rust prevention process takes about 7 to 8 hours.

Whenever possible, a less viscous oil should be used to keep the oil path clear. For example, in the high temperature season or under the condition of severe engine wear, the selection of high viscosity oil is conducive to the formation of oil film and reduces engine wear. Engine repair agent is a car maintenance product that repairs the most motivated problem in the field.

Oil consumption is not severe enough to survive the cycle between maintenances, but in the summer due to the hot weather, oil consumption will be a little higher than usual. If it is found that there are impurities or gasoline smell in the engine oil during the daily inspection, and the exhaust smoke is light blue, it means that there is a problem with the engine, and the parts may be abnormally worn, so you should enter the factory for maintenance as soon as possible.

1.Engine oil, that is, engine lubricating oil, can play a role in lubrication and wear reduction, auxiliary cooling and cooling, sealing and leakage prevention, distribution anti-rust and anti-corrosion, shock absorption and buffering and so on. It is known as the "blood" of automobiles.

2.Engine oil is made up of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of lubricating oil.

3.The 5W W-30 and so on in the engine oil indicate the viscosity grade of the engine oil, which is the SAE grade. "W" means winter.

The smaller the number in front of w, the smaller its low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature. The number after w does refer to the viscosity of the oil at 100 degrees Celsius, and the higher the number, the more viscous the oil. The number behind the spine mainly refers to the index of the high temperature resistance of the engine oil, and the better the protection performance at high temperatures.

4.There are the following brands to choose from, Shell, Castrol, etc.
