How to solve the problem of tire noise and wind noise in the car?

Attention should be paid to a good solution in terms of equipment, and at the same time, attention should be paid to replacing tires, and care should be taken not to have too much air leakage sound, so as to ensure the safety and firmness of the tires. This will solve the problem.

The car should be added in time, put it in a special repair shop for testing, repair the car tires, and test the parts in the car to see if there is serious wear and tear, replace it in time, and at this time, you also need to change the oil in time to reduce the viscosity of the oil.

First of all, check whether there is a problem with the tightness and sealing strip of the car, and then check whether there is a problem with the tire, if there is a problem with the tire, you can go to the 4S shop to repair the tire.

The brands on the list of automotive tire brands are: Michelin, Goodyear, Bridgestone, Continental, Dunlop, Pirelli, etc.

The easiest way to do tire noise insulation:

1. Choose tires with better quietness, with specially designed sound insulation strips, which can reduce tire noise.

2. To do a good job in the sound insulation of the car, you can use sound-absorbing cotton, shock-absorbing glue, special wheel arc lining plate and other materials. Vehicle sound insulation can be divided into door sound insulation, chassis sound insulation, trunk sound insulation, and hood sound insulation.

3. Maintain proper tire pressure to reduce the impact of abnormal tire pressure on tire noise.

4. Try to choose to let the car drive on a smoother road surface with better road conditions, which can reduce friction and tire noise.

5. Regularly clean up stones or other foreign objects in the pattern ditch.

Introduction: The sudden increase in tire noise may be due to uneven wear of the individual tires of the car, and once the wear is more severe, it will cause the tire noise to continue to increase. It is also possible that the tire pressure of the car tire is too high or too low, and the tire pressure is too high, which will cause the tire rigidity to become greater and the tire noise to increase; If the tire pressure is too low, the contact area between the tire and the ground will also increase, and the friction resistance will increase, resulting in greater tire noise.

Tire pressure that is too high or too low can also cause tire noise to become louder, and the faster the car goes, the more noisy the tire will be.

It should also be noted that replacing tires that are inconsistent with the original tire pattern, specifications, brand, etc. will also affect the tire noise; Moreover, it should be noted that the asymmetrical pattern needs to be installed on the inside and outside, and the installation direction of the single guide pattern should be consistent with the rolling direction of the tire. In addition, dynamic balancing should be carried out after the tire is replaced to avoid causing the tire to wear eccentricly, which can cause noise.

The steps to solve the noisy car tires are as follows:1. Regularly remove stones or other debris in the tires, which can solve the problem of tire noise.

2. The problem of high tire noise can also be solved by maintaining proper tire pressure.

3. If it is caused by uneven tire wear, it can be solved by doing four-wheel alignment. In order to prevent uneven tire wear, four shifts should be implemented regularly to reduce tire noise.

4. The driving speed and the flatness of the ground are also factors that affect the tire noise.

Car noise is annoying. In daily life, due to mixed noises such as car noise, tire noise, and road noise, the car is not quiet when driving, and there is annoying noise. Vehicle noise not only increases the fatigue of drivers and passengers, but also affects the driving safety of vehicles.

On the other hand, noise also has serious adverse effects on the digestive and cardiovascular systems, which are not as simple as they sound. Today we will talk about tire noise and wind noise, which are common in cars.

First, tire noise.

General tire noise is mainly composed of three parts:

1.Air noise caused by air flow in the tread clearance of empty tires and air disturbances around tires; 2.tire vibration noise caused by vibration of carcass and tread parts;

3.Road noise caused by uneven road surfaces.

Tire noise is unavoidable, even with so-called low tire noise tires, there is no effect. The key is to look at the sound absorption and insulation effect of the vehicle itself. At present, the firewalls of new cars below 300,000 are basically not sound absorbent and insulated, resulting in engine sound and tire noise entering the car through the dashboard and chassis fenders.

Solution: Tire noise is usually caused by the vibration of tires and treads or the friction impact of the tread and the ground, which resonates with the vibration of fenders, fenders, etc. And it is amplified and transmitted into the car.

Therefore, our measures to reduce tire noise can be solved by attaching sound insulation materials to the doors, door edges, parts above the wheel arc, fenders and chassis.

2. Wind noise. Wind noise refers to the pressure at which the oncoming wind enters the car at high speeds that has exceeded the sealing resistance of the doors. The faster the driving speed, the greater the wind noise (mainly through the sealing gaps of the four doors, including the generation and transmission of the entire thin steel plate).

The body itself is like a box, and the sound itself has the properties of refraction and overlapping. When the sound is transmitted into the car, if there is no sound-absorbing and sound-insulating material to absorb and block it, the noise will continue to be refracted and overlapped, forming a resonant sound.

Solution: Wind noise is generated due to the wind pressure exceeding the sealing resistance of the door, so strengthening the sealing resistance is the most direct and fundamental solution, and the door sealing strip and the inner sealing strip can solve this problem very well.

Third, the tightness of the car is still very important. What do I need to pay attention to when buying car weatherstrips?

1.Seals are elastic.

Strong elasticity and flexibility can enhance the sealing effect and extend the life of the sealing strip.

m adhesive backing. The dense shirt round seals produced by regular manufacturers are made of 3M glue, which has strong adhesion and can be pasted firmly without adhesives.

3.Waterproof tanks.

High-quality seals are equipped with waterproof grooves for increased waterproofing performance.

4.Smell. The surface of the sealing strip made of ordinary rubber is bright, there is no obvious peculiar smell, and the swimming collapse file is non-toxic and harmless. If the owner of the car has a noticeable odor, he should be careful. After all, he has always emphasized that the air quality inside the car is empty.

In fact, the "whole body" of the car is the noise**. When there is noise in the car, it is necessary to find out the different noises in the car in a targeted manner**, so as to prescribe the right medicine. There are four types of general car noise**: engine noise, tire noise, air noise and noise caused by body structure.

Millions of car purchase subsidies.

1. Tire noise.

The general tire noise is mainly composed of three parts:

1. The air noise caused by the air flow between the tire pattern gap and the air disturbance around the tire;

2. Tire vibration noise caused by the vibration of the carcass and tread parts;

3. Road noise caused by uneven road surface.

Tire noise is inevitable, even if the so-called low tire noise tires are not effective, the key is to look at the sound absorption and sound insulation effect of the vehicle itself, now the new car firewall below 300,000 is not sound absorption and sound insulation, resulting in engine sound and tire noise through the dashboard, chassis fenders into the car.

Solution: Tire noise is generally caused by the vibration of tires and patterns or the friction impact of the tread of the tassel and the ground, and the vibration of fenders, fenders and other components resonate and amplify into the car, so our way to reduce tire noise can be solved by the door, door edge, above the wheel arc, fender and chassis pasted with sound insulation materials.

<><1. Isolated midrange: Reduce tire noise by blocking the propagation of tire noise to the cockpit reed. In addition to removing the front and rear seats and interior trim of the vehicle, the tires and fender lining were also removed, and sound insulation materials were applied to the four doors, door sides, above the wheel arc, the four fenders and the chassis.

2. The method of replacing comfortable tires to reduce tire noise: the factors related to noise and tires are mainly tread patterns, so comfort tires will take into account the quietness when designing the tread.

3. Clean up the debris: the tire noise is high, and the Mingmo Mountain is solved by regularly cleaning the stones or other debris in the tire.

Tire noise is the noise of air squeezing when the tire rolls over the road, as well as the noise of friction and bending.

Tire noise is related to the tread material and pattern design of the tire, and it is also related to the quality of the road surface.

Asphalt pavement is usually much quieter than concrete pavement, but there is usually no way to choose which way to go. Therefore, it is completely unrealistic to deliberately choose a driving route in order to reduce tire noise.

In addition, using the method of reducing tire pressure to reduce tire noise will have some effect, but it is definitely not recommended! Inappropriate tire pressures for the brigade can lead to fuel consumption and safety issues, and are therefore unrealistic.

There are three most realistic methods: one is to do vehicle sound insulation, especially the dismantling of the wheel socket part of the sound insulation to reduce noise is more obvious. The second is to change the silent tires. The third is to get used to it, and to get used to it when you listen to it.

The sound of tires rubbing the ground, you can replace the silent tires, if there is no effect after replacement, then it may be that the sound insulation effect of the vehicle is not good.

Hello landlord! To solve the noise of the car tires, one is to replace the silent tires. For example, Continental or Michelin, the second is to upshift and install shock absorbers and soundproof cotton at the position of the closed smile liner in the upper part of the tire. Such as satisfied!

1. Tire noise cannot be completely avoided, the simplest and most effective way to reduce tire noise is to adjust the tire pressure of the leaky luggage to a moderate state, the tire pressure is too high, and the noise will increase. In addition, if the economic conditions allow, it is recommended to replace the static single tire, which has a special pattern and can reduce tire noise to a certain extent.

2. The good sound insulation effect of the vehicle is also the main way to reduce tire noise, and the only way for tire noise to propagate to the cabin is to do a good job of shock absorption, sound insulation, sound absorption, and buffering, and the main propagation parts include: chassis, fenders, and wheel arcs; The materials used mainly include shock-absorbing glue, sound-absorbing cotton, and special wheel arc lining. Because of the complexity of sound insulation, it is recommended that the owner should go to a professional maintenance point for the replacement of relevant materials.

3. The so-called tire noise is generated by the friction between the tire and the road surface when the vehicle is driving, and the nucleus is pure and transmitted to the car through the four doors, trunk, front fenders, front wheel arc and other parts, the tire noise depends on the road conditions, the worse the road conditions, the greater the tire noise, and the tire irritability generated by the asphalt road and the concrete road surface is very different.
