Why is the effect of tire sound insulation not good when the car is done?

1. Car sound insulation is divided into local sound insulation and whole vehicle.

Soundproofing, not all vehicles are suitable for doing.

The sound insulation of the whole car, some cars themselves are not badly insulated, or only a certain part of the sound insulation.

The tone is not in place, and there is no need to do it at this time.

The whole car is soundproof, as long as it is targeted.

All right; 2. Some people think that the sound insulation effect of the whole car will.

Obviously, but practically, like an engine.

Noise, sheet metal vibration and other noise belong to the middle and high frequency, which can be isolated by sound insulation, and like tire noise, especially the sound of the exhaust pipe, it belongs to the middle and low frequency, which is often difficult to isolate;

3. In addition, the sound insulation of the whole car needs to be removed.

The door panels of the four doors, the wheel arches of the four wheels, the seats, and even the center console were removed in pursuit of high ones, and various soundproofing materials and shock absorbers were laid.

Wait, and then put the dismantled things back in, which is equivalent to a big hand on your vehicle.

Technique. If it is an unprofessional tuning shop, it is very likely that it will bring sequelae to your vehicle, and then it will be troublesome.

For example, if you send tires for car sound insulation, it is mainly to isolate tires, and you are like other engine exhaust noise and land noise, so it is highlighted.

What effect? Soundproofing? This thing itself is minimal, and the psychological effect is greater than the actual effect. The effect is definitely there, and it has to be measured with a measuring instrument.

How to isolate the noise of the tires is obviously fooling.

The sound insulation of the wheel hub is done according to the needs of the owner, and the tire noise of some cars is very large, and it is very necessary to do the sound insulation of the wheel arc and fender for these cars. To be a soundproofing brand, it is recommended that you use Great White Shark car soundproofing, which is relatively good.

Related Notes:The car rim is the part of the wheel where the axle is installed in the center of the wheel, which is often referred to as the "rim" or "steel rim". The wheel hub is easy to get dirty, and if it is not cleaned for a long time, it may be corroded and deformed, resulting in potential safety hazards. Therefore, special attention should be paid to the maintenance of the wheel.

The main advantage of steel wheels is that the manufacturing process is simple (generally using the casting process, for example, aluminum alloy wheels are generally produced by low-pressure casting process), the cost is relatively low, and the ability to resist metal fatigue is very strong, which is what we commonly call cheap and strong.

I think it depends on the level of your car, the words of the common people, they are not so particular, and the general tire noise has no obvious effect; If you're a car perfectionist and want to dress up your car as the perfect car, then you can not only add sound insulation, but also get any side skirts, rear wings, fins, and what you can get on. In short, it's a personal favorite, but none of my colleagues or friends have heard of them adding wheel soundproofing. Hope it helps.

Wheel hub sound insulation is also known as fender sound insulation professionally, which can greatly reduce the incoming road noise and tire noise. Therefore, fender soundproofing is also very important.

The function of the automobile wheel hub is: the part of the axle is installed to support the tire, cushion the external impact, realize the contact between the tire and the road surface, and ensure the driving performance of the vehicle.

It is installed with another wheel liner that is better than the original wheel liner sound insulation and vibration damping effect, the original car is similar to rubber, and the material used in the wheel liner is the material corresponding to the reduction of tire noise, and the installation is softer than the original car, and the sound emitted when the vibration is smaller than that of the original car, and the sound insulation effect is better, and then let some stones splash on the wheel liner to produce a smaller blow sound, which is probably what it looks like

If necessary, tire noise can be reduced.

Changing tires can reduce noise, and the first 10,000 kilometers after changing tires will be obvious, and the effect will decrease as the tires age.

The wheels of sedans generally use radial tires. The specifications of radial tires include width, aspect ratio, inner diameter and speed limit symbol. Take Toyota sedan as an example, its tire specification is 195 65R15, which means that the width between the two sides of the tire is 195 mm, 65 represents the aspect ratio, and "R" stands for the word radial, which means that it is a radial tire.

15 is the inside diameter of the tire, measured in inches.

As the speed increases, the diameter of the tires decreases in order to lower the center of gravity and axle of the car. In order to ensure sufficient load capacity and improve driving stability and grip, the width of the wheel rim has to be continuously increased. Therefore, the cross-sectional shape of the tire has developed from the original approximately circular to a flattened oval.

The characteristics of this tire is that the direction of the cord cord arrangement is consistent with the radial section of the tire (that is, the crown angle of the tire is zero degrees), due to the arrangement of the cord, the strength of the emperor wire can be fully utilized, and the number of cord layers of the radial tire can generally be reduced by about 40-50% compared with the ordinary slash tire. The cords are connected only by rubber in the circumferential direction.

Under normal circumstances, the tires cannot be soundproofed.

If the noise of car tires is too loud, you can choose to replace the silent tires with soft rubber and special tread patterns, which is one of the solutions to solve tire noise. The rolling friction of tires on the road surface will produce a lot of noise, and these noises are closely related to the material and structure of the road surface. Driving in a road environment with good hardware and software can reduce most of the tire noise.

The material, pattern, and size of the tire will affect the tire noise, generally speaking, the harder the tire material, the louder the noise; If the tire pattern is not specifically designed for silence, it will also produce a lot of noise if the air is squeezed at high speeds.

Tires are not recommended to be soundproofed.

Abnormal tire noise is generally caused by abnormal tire wear, if you feel that the tire noise increases, you can try to regularly clean up the stones in the tire pattern, which can protect the tire and reduce the tire noise.

Generally speaking, the tire noise becomes less when driving after rain, and the tire noise becomes more after washing, due to the mud absorption on the inner fender. This can be avoided by gluing a layer of black felt or flannel to the inner fenders of the front wheels.

When using the car daily, adjust the tire position every 10,000 kilometers, check the four-wheel alignment every 20,000 kilometers, and correct and adjust if there is an abnormality.

The formation of tire noise is mainly determined by the tires and the road surface, so what about tire noise solutions? If the road conditions cannot be changed, the problem can only be solved by replacing the tires. Generally speaking, the pattern accounts for 70% and is also affected by tire pressure.

If the conditions are good, you can choose to change the tires, or you can reduce the impact of tire noise by insulating the sound.

1. The reason for the noisy tires of automobiles.

70% of car tire noise comes from tread design, while only 30% of truck tires are affected by tread design. But the factors that affect tire noise are not only the tread design, but also related to tire pressure, actual load, driving speed, etc. Generally speaking, the faster you drive, the louder the tire noise.

Undervoltage, overload, high pressure, and underload are not ideal tire working conditions, and have an obvious impact on noise.

Second, the solution to the high tire noise.

So how to solve tire noise? The most direct and effective way is to adjust the tire pressure to a moderate state and make appropriate adjustments according to different road conditions. It's troublesome, but it's the most economical and simple.

Of course, if you can, it is recommended to switch to silent tires. The rubber of this tire is relatively soft and has a special pattern, so the tire noise is relatively small, but generally this tire is not wear-resistant, so it is not only expensive, but also has a relatively short service life.

The other is to do sound insulation work, and do a good job of shock absorption, sound insulation, sound absorption, and buffering on the road where tire noise is the only one that spreads to the cabin. The main components are chassis, blade plate and wheel arc, and the materials used mainly include damping glue, sound-absorbing cotton and special wheel arc lining. Because the soundproofing work is complicated, we have to go to the repair shop.

<> "Car tires are too noisy and need to be replaced.

Acoustic insulation is used to eliminate tire noise. In fact, any car has tire noise, but the size is different, but the lower the grade of the car, the stronger the tire noise, which is mainly because the sound insulation effect is not good, so, in view of this situation, you can use sound insulation materials to eliminate the tire noise of the car, first of all, the door, in the gap of the door, the use of sound insulation materials, and the above part of the wheel arc, four fenders and the chassis are pasted with sound insulation materials.

Learn to adjust tire pressure to eliminate noise. In many cases, tire noise is also caused by the excessive tire pressure of car tires, and the tire pressure must be too high, so that the tire will appear hard, which directly leads to a decrease in the elasticity of the tire. Of course, if the tire pressure is low, tire noise will also occur, mainly because there is too much contact with the ground and too much friction with the ground.

So there was a ring. Therefore, everyone must pay attention to adjusting the tire pressure of the car. in order to reduce tire noise.

Clean up small stones from your tires. There are some situations where we usually drive without tire noise, but suddenly tire noise occurs, what is going on? The general reason is that there are small stones in the tire gap, so that there is a lot of friction with the ground, and tire noise will occur, so the old driver who knows how to use tools to clean up the small stones in the tires, which can eliminate the tire noise, and the small stones are also easy to cause car punctures.

Therefore, the Big Oak State Eggplant must be cleaned up in time.

Learn to drive on flat roads. In fact, the tire noise of the tire is also related to the condition of the road beam, if you drive without choosing the road, then it will inevitably rain on a rainy day, always drive in the waterlogged place, so that for a long time, it will also produce tire noise, so we must learn to choose a flat road to drive, away from the puddle road.

Open the window to remove the noise. If your car has a sunroof, then you can use the sunroof to eliminate tire noise, the main reason is because after the sunroof is opened, it can be ventilated in time, but it is worth reminding everyone that do not open the sunroof all, otherwise there will be a lot of wind noise, which will also affect the comfort, and it is enough to open a gap. In this way, the air in the car will be smoother.

The tire noise will be much reduced.

In addition to judging the performance of a car, it looks at the engine, chassis performance, and gearbox.

Exterior soundproofing is also an important criterion. If the sound insulation of a car is too poor, it will not only make people irritable when driving for a long time, but also make their vehicle feel less "advanced". There are not a few vehicles with poor sound insulation when leaving the factory on the market, so many car owners will choose to do four-wheel sound insulation in the later stage to improve the sound insulation effect, but a few people find that the tire noise is greater after doing it.

This situation is possible, first of all, the most important point is the construction process and material selection, if the construction process is too poor or the selection of the material itself is problematic, the effect is certainly not satisfactory, and if the sound insulation cotton is in the driving.

The peeling of the tire will cause the tire to rub against the soundproof cotton for a long time, which will also cause a significant increase in tire noise. Secondly, four-wheel sound insulation is not as useful as we think.

The best way to solve the problem of tire noise is to replace the silent tires, and each brand will launch a series of silent tires. Compared with ordinary tires, silent tires have a much better silent effect. At the same time, if you choose a run-flat tire, it will also cause more obvious tire noise.

If the effect is still limited after changing the silent tire, you should consider a spare tire for the vehicle.

I added soundproofing cotton at the place. Many vehicles are not equipped with soundproof cotton in the spare tire slot, which is the loudest noise for some models.
