How often does it take to maintain the suspension system of automobile chassis parts?

Car chassis. The suspension system is generally maintained once for 50,000 kilometers, and the maintenance items are: check the shock absorption system, replace the shock absorber assembly, various support arm tie rods, and check the degree of tire wear.

The chassis suspension system of the car is usually serviced once every 50,000 kilometers. Maintenance items: check the shock absorption system, replace the shock absorber assembly, various arm tie rods, and check the degree of tire wear.

Automobile chassis suspension, if there is a major accident, it must be replaced in time, if not, maintenance, maintenance once every two years.

There is no fixed maintenance cycle for the driving chassis, only the need for regular inspection, the main thing is to lift your vehicle up every time you maintain it, and then take a look at it through visual inspection, and when you find that there is an abnormal situation in the driving, you should do some maintenance in time, such as the common clanging noise, or there is a deviation to eat the tire, the steering machine is obviously heavier than before, and you have to check some data of the chassis suspension.

The chassis suspension system of the car does not need maintenance, and it is normal to check whether the chassis bolts are loose when doing maintenance.

For example, the rubber of the suspension is replaced according to the degree of aging of the rubber and the time. In general, the rubber life time is within two to three years. It is recommended to replace the rubber wear parts within three years. I hope to adopt.

1. The maintenance items include checking the shock absorption system, replacing the shock absorber assembly, various arm tie rods for potato residue, and checking the degree of tire wear and trouble;

2. The chassis suspension system is the general name of all the force transmission connection devices between the frame of the car and the axle or wheel;

3. The main function of the suspension is to transmit all the forces and moments acting between the wheels and the body, such as the supporting force, braking force and driving force;

4. And alleviate the impact load transmitted to the body by the uneven road surface, attenuate the vibration caused by it, ensure the comfort of the occupants, and reduce the dynamic load of the goods and the vehicle itself.

The automobile chassis suspension system is usually maintained once every 50,000 kilometers: 1. The maintenance items include checking the shock absorption system, replacing the shock absorber assembly, various arm tie rods, and checking the degree of tire wear; 2. The chassis suspension system is the general name of all the force transmission connection devices between the frame of the car and the axle or wheel; 3. The main function of the suspension is to transmit all the forces and moments acting between the wheels and the vertical body of the car, such as supporting force, braking force and driving force; 4. And alleviate the impact load transmitted to the body by the uneven road surface, attenuate the vibration caused by the disorderly response, ensure the comfort of the occupants, and reduce the dynamic load of the goods and the vehicle itself.

The so-called suspension system is to carry the body, absorb the vibration between the wheels and the body, and provide the best ride comfort. Usually, shock absorbers are hot when they work. Otherwise, it means that the shock absorber is leaking.

During driving, the suspension system makes a "claw" sound whenever the vehicle vibrates up and down. When the road surface is uneven, the sound increases, which indicates that there is a malfunction in the suspension system, possibly a damage to the shock absorber or the rubber sleeve of the shock absorber.

Suspension - shock absorber check.

The suspension system not only affects the ride comfort of the vehicle (ride) through the impact on other properties, stability and adhesion, etc. But it is included in the suspension system, shock absorbers, springs, anti-roll bars, rods and other components. Further, especially when in a sharp turn, the body rolls too much, the shock absorbers described, the stabilizer bars, or the guiding components are damaged.

Brake system, brake oil, brake pads.

In daily use, it is necessary to pay attention to check whether the vehicle is moving, how good the braking performance is, and the effect of the parking brake (hand brake). When the vehicle is repaired, the braking system should first check the brake oil, such as whether the brake pipe is broken, whether the brake fluid is leaking, etc. The brake pedal is also a part to look out for.

After replacing the brake pads, check that the brake pedal returns normally, and pay attention to prevent the pad brake pedal from sliding under the pad during daily driving, so as not to step on the brakes.

Brake system brake fluids are not currently mixed, and most cars on the market are equipped with two braking systems: foot-operated service brakes (brakes) and hand-operated parking brakes (hand brakes). When changing the brake fluid, be sure to polish the original brake fluid, it should not be mixed together, and there is less air in the brake fluid that can be mixed.

Generally speaking, the degree of wear and tear of brake pads has a lot to do with usage habits. Automatic brake pads are more expensive than manual brake pads. Generally, after driving more than 20,000 kilometers, the sprinkler brake pads should be checked every time they are maintained.

This allows for better protection of the suspension system. If the rubber sleeve is badly damaged, the shock absorber should be repaired and replaced.

Suspension - shock absorber check.

The suspension system not only affects the ride comfort (ride comfort) of the car, but also affects other properties such as passability, stability and adhesion. It turns out that the suspension system includes shock absorbers, springs, anti-roll bars, connecting rods and other parts. When cornering, especially when making sharp turns, the body rolls too much, indicating damage to the shock absorbers, stabilizer bars, or guide mechanism components.

After replacing the brake pads, check whether the brake pedal return is normal, and pay attention to prevent the foot pad from slipping under the brake pedal during daily driving, so as not to prevent the brake from being stepped on.

Clean the vehicle in time after driving in bad road conditions, especially the chassis, suspension, wheels, tire fenders and other positions to prevent corrosion. If there is a large abnormal noise in daily driving, it should be checked in time, and the speed of the vehicle should be reduced when passing through the pothole, so as to reduce the impact on the suspension of the vehicle. Prevention is greater than the first, frequent inspection, frequent maintenance, timely treatment and maintenance in the early stage of the problem, to avoid "minor illness" dragged into "major disease".

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 well maintained, directly related to the safety, handling, comfort and economy of the car and other key performance, can not be taken lightly.

1. Clutch system.

1) The clutch booster rubber parts and dust jacket cycle is 80,000 kilometers or about 3 years of use.

2) Clutch booster oil, service life of 80,000 kilometers or 3 years.

3) The clutch friction plate is 80,000 kilometers, and the depth of the rivet should not be less than.

2. Brake system.

1) The general wear of the brake drum cannot exceed 2mm, which means that if it exceeds this value, it is a replacement cycle.

2) The use of brake discs and brake drums is the same, and the limit wear cannot exceed 2mm, and they must be replaced if they are exceeded.

3) Brake pump rubber parts and dust jacket. The service life is 80,000 km, or about 3 years.

4) Brake fluid, also known as brake fluid. The service life is 80,000 km or 2 years.

5) Brake hose. This general car repairer knows that the cycle is 80,000 kilometers or 3 years.

Figure 4-116 Checking the spring.

2.Inspection of shock absorbers.

1) Check whether there are dents on the shock absorber. Also, inspect the dust cover for cracks, cracks, or other damage. At the same time, check the shock absorber for oil leakage.

2) Check whether the shock absorber bolts are loose.

3.Check the suspension connection swing.

Check the bushing for wear or cracks by shaking the connection on the suspension joint by hand, and check for swing.
