Will there be abnormal sound of the airbag hairspring, and what is the abnormal sound of the airbag

You can disassemble the downstream wire and then test it, if there is no abnormal sound after dismantling, replace it.

If you find that the sound is coming from the steering wheel, most of them are caused by the interference of the airbag hairspring in the steering wheel, remove the steering wheel airbag hairspring and apply some butter to see if it still sounds, if it still sounds, replace the airbag hairspring.

If the airbag hairspring is broken, the horn will not sound, the airbag light will be on, and the steering wheel audio control button will not work. The hairspring is a ring-shaped part that connects the airbag to ensure that there is still an electric current entering the airbag when it follows the rotation of the steering wheel, and the wires inside will not break due to frequent rotation and twisting, so that the airbag can ensure its operation at any time.

Precautions. The importance of airbags goes without saying, and the airbag balance spring is the wiring harness that ensures that the airbag can detonate normally in an emergency. Because the main airbag rotates with the steering wheel, there should be a margin for the connecting wiring harness to ensure that the steering wheel is turned to one side to the limit position without being broken.

This is especially important when installing, and try to keep it in the middle.

Taking Corolla as an example, the replacement of the airbag hairspring in the 4S shop is 600-800 yuan, and the replacement of the outside auto repair factory is 200-500 yuan, so it is not expensive to replace the airbag hairspring for 300 yuan. However, the ** of the airbag hairspring will also change according to the model, if the car is more advanced is a luxury brand, then the replacement of the airbag hairspring will also be increased accordingly, and the specific ** must be subject to the actual situation.

The abnormal sound of the airbag hairspring cannot be solved by oiling. The sound of the oil spool of the airbag is difficult to solve, and it cannot be solved if you add 1 point of lubricating oil to it, because it is fully sealed, and there is only one way to solve the problem of replacing the airbag balance spring.

Product Introduction. In the event of a car crash, airbag systems are effective in protecting the safety of drivers and passengers.

At present, airbag systems are generally steering wheel single airbag systems, or dual airbag systems. Twin airbags and seat belts are installed.

When the vehicle of the pretensioner system collides, regardless of the speed, the airbag and seat belt pretensioner act at the same time, so that the airbag is wasted during the low-speed collision, and the maintenance cost increases a lot.

The two-action dual airbag system can adapt to the speed and acceleration of the car in the event of a collision.

The size automatically selects whether to operate only with the seat belt pretensioner or with both the belt pretensioner and the dual airbag at the same time. In this way, in the event of a collision at low speeds, the system can protect the occupants with only seat belts without wasting airbags.

If a collision occurs at a speed greater than 30 km h, the seat belt and airbag operate at the same time, so as to protect the safety of the driver and passengers.

The airbag balance spring is damaged.

The role of the airbag hairspring is similar to that of the "wire", the airbag hairspring is to ensure that the steering wheel can still be energized in the case of rotation, and the car horn is an electric horn that needs to be transmitted by the driver to press the steering wheel to convey the electrical signal, so if the airbag hairspring is damaged, the horn will not sound, and the function buttons and airbags on the steering wheel cannot work normally, which seriously affects daily use. Therefore, when the airbag hairspring is damaged, we should replace it in time.

The ** of replacing the airbag hairspring in the 4S shop is 600-800 yuan, and the ** replaced by the outside auto repair shop is 200-500 yuan, so it is not expensive to replace the airbag hairspring for 300 yuan. However, the airbag hairspring will also change according to the model, if the user's car is more advanced, is a luxury brand, then the replacement of the airbag hairspring will also be improved accordingly, and the specific ** will be subject to the actual situation.

The airbag hairspring is easy to damage, in fact, it has a certain relationship with the usual driving habits, when the steering wheel kills the letter beat to the left and right, the airbag hairspring is easy to be pulled off. Secondly, if the vehicle is older, the airbag hairspring is also more likely to be damaged.

If the airbag hairspring is often damaged, you can check whether there is any foreign object in the installation position of the airbag hairspring, if there is a foreign body or improper installation, the wiring in the airbag hairspring is easy to break and cannot be used.

The abnormal sound of the airbag hairspring needs to be repaired, and now it will make a friction sound when playing the direction, the sound is sharp, very small, and you can't hear it carefully, the steering wheel is not abnormal, and the motor is not abnormal, mainly because the steering wheel hairspring has a problem, and you only need to go to the repair shop to replace it with a new one.

The airbag hairspring will affect safety, and the hairspring is a part of the automobile airbag, also known as the spiral cable, which is installed under the steering wheel and is an important part of the electrical connection between the electrical appliances on the steering wheel and the directional column.

The impact of the broken hairspring:

1. If the steering wheel hairspring is broken, the horn will not sound, the airbag light will be on, and the steering wheel audio control key will not be used.

2. The hairspring is a ring-shaped part connecting the airbag, and its design can ensure that the current still enters when the airbag follows the rotation of the steering wheel, and the wires inside will not be broken due to frequent rotation and twisting, so that the airbag can ensure its work at any time.

3. If there is a problem with the hairspring, then the airbag will be scrapped, and if it is an accidental ride, it will even explode by mistake.
