If you re replacing your car s airbags, what s the first thing you ll consider?

Introduction: In today's society, there are cars are very common, I believe that every car owner, in order to drive safely will be installed in the main driver and co-pilot of the car airbags, in order to reduce accidental traffic accidents, a kind of trauma to the driver. Therefore, it is very effective to install airbags in the car.

And after an accident, the airbag should be replaced in time, so what is the first thing to consider when replacing the car airbag? <>

One:What role do airbags play in accidents?

In people's daily driving, vehicle accidents are frequent. Then when there is a traffic accident, the role of airbags is very large. The function of the airbag is reflected in the fact that if the vehicle is violently attacked, it will be activated instantly, and the state of an airbag will be quickly formed to protect the driver and reduce the violent impact with the vehicle and reduce the driver's body abrasions, so as to better protect the safety of the driver.

Two:What to know when replacing an airbag?

The role of airbags can not be ignored in daily life, so we should also pay attention to the replacement of airbags, before disassembling must be lighted to check whether the airbags are working properly and then replaced, can not use some simple tools, such as detection lights to check, and then use some professional equipment to check, and then when dismantling, it must be disassembled in the case of the car turned off. Also, when disassembling, do not touch the sensor and turn the steering wheel sharply, and do not smoke when replacing the airbag, and replace the airbag carefully. After replacing the airbag, be sure to keep it properly.

Three:How often do airbags change?

Everything has a useful life and time, and when the car is installed with airbags, it must be replaced for a certain period of time to avoid being unable to deploy normally in an emergency. In general, airbags can last for seven to ten years without incident. In daily life, the owner should also repair and maintain the airbag, and if an accident occurs, the airbag is used to replace it in time, so as not to pop up normally next time, and there is no way to better protect the life safety of the owner and relatives.

The first thing to consider should be what kind of air is in the airbag, and how long the airbag will open directly, and then the airbag will be tested before use, after all, it is our life, and it must be treated strictly.

I will consider the cost, if the cost is particularly high, then it will not be replaced, and the cost performance is quite low.

The first thing I think about is the safety of the airbag and the quality of the airbag, because the airbag is a matter of life.

If you want to replace the car airbag, the first thing to consider is whether the airbag is the original of the car.

Foreword: Airbags.

In the process of driving the owner, the life of the owner and passengers is guaranteed, so the airbag is very important to us, and it is also the item that the manufacturer must install, so what happens to replace the airbag?

1. Where is the car airbag located? Many people don't even know that the car's axle airbag is in the end, which will be briefly explained. The airbags of the car are mainly distributed in front of the interior of the car, that is, the position of the front and co-pilot.

Or the side, that is, the front and rear seats in the car and the roof, and the car's airbags are printed with the S R S logo on the outside. Many drivers are familiar with the airbag located in the driver's seat, which is located on the steering wheel.

The airbag in the center disc and the passenger seat is generally in the front panel.

Second, the car airbag is opened, if you are in the process of driving, trigger the car's airbag, then the airbag should be replaced in time. Theoretically, when the front of the vehicle is about 60 degrees to the left and right. Impacting a stationary object at a speed above 30 km/h allows the car's airbag to deploy.

However, depending on the design of the vehicle, it may vary slightly depending on the model. If the car's airbags are able to open normally in the event of an accident, and you wear your seat belts correctly.

Then the airbag will successfully save your life. However, if the airbag in your car is suddenly activated under normal driving conditions, it may cause your life to be in danger.

3. ConclusionSo in the process of normal driving, the driver must pay attention to whether the vehicle airbag can be used correctly, we do not use some inferior or refurbished airbags, if the spine of the development of these problems should be replaced in time.

The airbag has exploded, and there is a problem with the airbag, so the airbag needs to be replaced, and the right one must be chosen.

If the vehicle has a serious collision and the vehicle airbag deploys, then the airbag needs to be replaced.

If the car has had a safety traffic accident, and the airbag has been used once or the airbag has been damaged, it is necessary to replace the airbag of the car.

If the airbag has been damaged, or because of a traffic accident, it needs to be replaced.

If the airbag pops out due to a safety accident in the vehicle, the car airbag should be replaced in time.

Generally, when the car has been driving for about 8 to 10 years, it is necessary to go to the 4S shop to check the performance of the car airbag.

As the name suggests, airbags are designed to ensure the safety of the driver and passengers. An airbag won't work when driving safely, but it will protect you in an emergency, especially in a head-on collision. Therefore, carefully understanding and maintaining the car's airbags is something that cannot be overlooked.

But when it comes to replacing an airbag, it's not an easy task, and here are the steps to replace an airbag:

When unpacking a new component, first check whether there are any foreign objects falling in to ensure that there are no foreign objects in the assembly;

Firstly, the pin in the assembly is aligned with the joint bottom plate and the hole on the steering wheel, then the component is firmly pressed on the generator-sensor assembly, and the fixing bracket holes on the component are guaranteed to be aligned with the holes on both sides of the steering wheel, if these fixing brackets are not installed in place, the cover can not be completely covered tightly on the assembly, and the effect of affecting the appearance is affected, pay attention to not to hit and knock any part on the component and the steering wheel during installation;

Install the bolts, maintain the pressure on the assembly, let the shell buckle intact, and install four bolts alternately from one side to the other, and the tightening torque is 7-11N·m;

Finally, install the covers on both sides.

The following procedures should be strictly followed when disassembling the airbag:

1. Wear fireproof gloves and protective goggles;

2. Disassemble the covers on both sides of the steering wheel;

3. Unscrew the four fixing bolts on both sides;

4 Carefully remove the airbag assembly;

5 Use a small screwdriver to turn the black plastic cleats outward, and carefully rotate the generator counterclockwise until the generator - the sensor seat is aligned with the steering wheel matching slot. Gently take the generator-sensor out of the steering wheel interface;

6. Turn the front wheel to the position in front of you, if you still need to continue to use the steering column and steering wheel, you should mark the relative position of the steering wheel and the steering direction, and then remove the fixing nut of the steering wheel, remove the nut and flat washer, and remove the steering wheel. And before installing the airbag, you should pay attention to: wear fireproof gloves and protective goggles; Smoking is prohibited during operation.

To replace the new airbag, first align the components correctly with each hole, press and fix them, and then fix the shell to it, and tighten the screws around it.

I don't know this very well, because I usually don't pay much attention to this aspect, if you need to replace, you should go to a professional repair shop to replace, so that there will be no hidden dangers when it is replaced.

If you want to save your life, the most effective and correct way is to send it to a 4S store to replace the original airbag.

Airbags are not as simple as changing parts for other things, they need the right signal, and each manufacturer has its own calibration type.

Summary. Pro, the steps to replace the airbag: When unpacking the new component, first check whether there is any foreign object falling in to ensure that there is no foreign object in the component; Firstly, the pin in the assembly is aligned with the joint bottom plate and the hole on the steering wheel, then the component is firmly pressed on the generator-sensor assembly, and the fixing bracket holes on the component are guaranteed to be aligned with the holes on both sides of the steering wheel, if these fixing brackets are not installed in place, the cover can not be completely covered tightly on the assembly, and the effect of affecting the appearance is affected, pay attention to not to hit and knock any part on the component and the steering wheel during installation; Install the bolts, maintain the pressure on the assembly, let the shell buckle intact, and install four bolts alternately from one side to the other, and the tightening torque is 7-11N·m; Finally, install the covers on both sides.

It is nitrogen, which expands in seconds, and there is a solid sodium azide in the airbag, which quickly generates a large amount of nitrogen after being impacted.

The gas in the car airbag is nitrogen, which will expand in seconds after dismantling, and there is a solid sodium azide in the airbag, which will quickly generate a large amount of nitrogen after being impacted, and the calculation formula is nan = nah + n, and the use of airbags can have the effect of protecting the safety of passengers in the car.

Role of car airbags: In the event of a road accident, car airbags help reduce the severity of injuries to the chest, head, and face in the event of a collision. Before a collision, the car stops moving, and the occupants of the car continue to move forward at the original speed under the action of the inertial force.

As the car stops moving, it gradually stops moving forward, and when the collision is more ferocious, the occupants move forward faster, even if they are wearing seat belts, they will still collide with the contents of the car until the seat belts bring the occupants to a complete stop. If the airbag installed in the steering wheel or instrument panel is inflated and popped out at this time, it can protect the occupants and reduce the possibility of collision with the objects in the car, more evenly disperse the impact force of the head and chest, absorb the movement energy of the occupants, and thus play a role in supplementing the effect of seat belts.

The working principle of the automobile airbag: during the driving of the car, the sensor system continuously sends speed change information to the control device, and the control device analyzes and judges this information, if the measured acceleration, speed change or other indicators exceed the predetermined value (that is, the collision really occurred), the control device sends an ignition command to the inflator or the sensor directly controls the ignition, and the first reaction occurs after ignition, generating N2 or releasing the compressed nitrogen in the gas storage tank to fill the collision air bag. When the occupants are in contact with the air bag, the collision energy is absorbed through the damping of the exhaust hole on the side bag of the air bag, so as to achieve the purpose of protecting the occupants.

What are the main gases used in automotive airbags?

Answer: The gas in a car airbag is nitrogen. The gas in the car airbag is nitrogen, which will expand in seconds, and there is solid sodium azide in the airbag, which will quickly generate a large amount of nitrogen after being impacted, and the calculation formula is Nan3=NAH+N2, and the use of airbags can effectively protect the safety of passengers in the car.

The main gases used in automotive airbags are:

Answer: There is solid sodium azide NAN3 in the airbag, which quickly decomposes to generate a large amount of nitrogen when it is violently impacted, so the airbag is filled with nitrogen Nan3=NAH+N2. An airbag system is a protection system for passive safety (see Automotive Safety Performance) that works in conjunction with seat belts to provide effective collision protection for occupants.

The main gases used in automotive airbags are:

Answer: It is mainly nitrogen, which can inflate the airbag in seconds, thereby protecting the driver's life, but these nitrogen gases are produced by the rapid decomposition of the solid sodium azide Nan3 in the airbag when it is subjected to a violent impact. It should be noted that when the occupants of the car are closed and deviate from their seats, the effect of the airbag will be counterproductive.

It will cause some damage to the people in the car.
