When does the car do four wheel alignment to balance

Why do cars do four-wheel alignment, this is a problem that the majority of users and drivers are very concerned about. Let's start with the construction of the car. Take most of the four-wheeled cars driving on the current road as an example, the installation between the steering wheel, the steering knuckle and the front axle of the car has a certain relative position, and the installation with a certain relative position is called steering wheel alignment, also known as front wheel alignment.

The front wheel alignment includes four contents: kingpin camber (angle), kingpin camber (angle), front wheel camber (angle) and front wheel toe. This is the relative position of the two steering front wheels and the rear axle for the two rear wheels, which is called rear wheel alignment. Rear wheel alignment includes wheel camber (angle) and rear-wheel toe-in by rear.

In this way, the front wheel alignment and the rear wheel alignment are collectively called four-wheel alignment.

The function of the four-wheel alignment is to keep the car stable and straight, and to steer lightly, and to reduce the wear and tear of the tires and steering parts of the car while driving. Due to the different original designs and manufacturing of the four-wheel alignment of various automobile manufacturers, the various inclination angles and beam values of each wheel are different, and there are adjustable parts and non-adjustable parts; Doing four-wheel alignment is to detect whether the inclination angle and beam value of each wheel of the tested vehicle meet the original factory standards through the four-wheel aligner, and if not, random adjustments can be made.

In other words, when the driver feels that the direction of the steering is heavy, shivering, misaligned, not homecoming, or finds that the tires are unilaterally worn, corrugated wear, block wear, eccentric wear and other abnormal wear, as well as the phenomenon of floating, jolting, and swaying while driving, he should consider doing four-wheel alignment.

1.The vehicle has mistracked.

The steering wheel has an automatic centering function, which is actually due to the accurate four-wheel alignment. If one day you find that the car will involuntarily deviate to the left or right, and you have to keep aligning the steering wheel to keep driving in a straight line, then you need to do a wheel alignment.

2.Tires are severely eccentric.

We usually don't check the tires carefully when driving, but we recommend that every 20,000 kilometers or 1 year carefully check the tire condition to see if there is eccentricity.

3.After an accident with a vehicle.

After the car is hit, if the suspension is damaged, the four-wheel parameters also need to be readjusted. In addition, the steering wheel fluttering, shaking or excessive weight during driving can also be caused by inaccurate wheel alignment parameters.

It is necessary to do a four-wheel alignment for general family cars during annual maintenance, and some vehicles that are frequently used under special conditions should be positioned every three months.

Under normal circumstances, after the car does four-wheel alignment, there will be some of the following benefits:

1. Increase the safety of driving.

2. Reduce the abnormal wear and tear of tires.

3. Keep the steering wheel straight when driving straight and keep driving in a straight line.

Tires are basically caused by two reasons, 1. The deformation of the wheel hub 2. The four-wheel alignment is set incorrectly, and the four-wheel alignment often causes the tire to be worn by the beam angle rather than the camber angle.

In this case, you need to do a four-wheel alignment for 20,000.

The role of car wheel alignment:

Tires benefit greatly.

Since it is called four-wheel alignment, it must be very beneficial to the tires in the first place. After the four-wheel alignment, the tires can maintain the optimal angle between the tire and the car body, which improves the grip and ensures comfort. Of course, if the vehicle does not carry out four-wheel alignment in the event of an abnormal phenomenon, it will not only have a greater impact on safety, but also greatly reduce the life of the tire.

The ** of a tire is about a few hundred yuan to several thousand yuan, if you don't take care of the tire, you will lose a lot of money.

Improved handling.

Keeping the tires in normal condition is of course very helpful for driving safety. After the four-wheel alignment adjustment, the driving handling can be guaranteed accordingly. Especially in case of emergency, the tires have enough grip to follow the driver's trajectory as much as possible.

Although this is only an emergency, there are certain dangers in driving, and if you can make a corresponding judgment at the moment when danger is imminent, I believe that your safety will be fully guaranteed.

The effect of fuel saving is good.

It is obvious that fuel consumption decreases with the decreasing coefficient of rolling friction of the tire. After the adjustment of the four-wheel alignment, the vehicle can follow the correct trajectory, which reduces the wind resistance to a certain extent, and of course, the fuel consumption will also be reduced. Combined with the standard tire pressure value, the tires not only maintain the best grip on the road, but also reduce the friction between the tires and the ground as much as possible, killing two birds with one stone.

Driving safety is guaranteed.

If the tires are good, the safety will be greatly improved. In fact, after adjusting the wheel alignment, the service technician will also check the condition of the car's suspension system and other (torture) components, and this inspection can determine whether the tires have an adverse effect on the chassis system. If an abnormality is found, not only the tires are optimized, but the chassis is also trimmed accordingly, so that the wear degree of the corresponding components can be judged through the tires, and the potential safety hazards can be found as soon as possible and completely eliminated.

If the dynamic balance is not good, it will shake badly when the 80 horses are on the high speed, if the four-wheel alignment is not good, the car will eat tires unilaterally, and if the gap is large, a new tire will be installed for a month, and it will be fully polished on the side, and the car deviates, some cars can be adjusted, and some have to go to the repair shop to pull the beams.

It's good to change it, but I don't know if it's charged, it's just that the four wheels are transposed. The most authentic transposition is to connect the spare tire and cross the five wheels.

For more information, please check Ekcar Cars.

Because if the wheel clearance is large, the car will automatically deviate

If the dynamic balance is not good, the steering wheel will shake at high speeds, and if the wheel alignment is not good, the car will eat tires or deviate.

Reduce fuel consumption, avoid unnecessary wear and tear, and maintain smooth driving.

Dynamic Balancing:

The new tire must be dynamically balanced. Theoretically, you have to balance the tire when you remove it from the rim and put it back on, because you can't restore the position of the removed tire and the rim.

Four-wheel alignment: 1) Routinely speaking, the car should be re-positioned every 8000-10000 kilometers or so, so at least twice a year to do the positioning inspection.

2) Check the tire wear at least once a month. If the tire wears unevenly, for example, one side of the tire shoulder wears out faster than the rest of the tread.

Or if you notice that your vehicle is shaking or mistracking, your vehicle may be poorly positioned or unbalanced. These conditions not only shorten the life of the tires, but also affect the handling of the vehicle and can be dangerous. If you notice irregular wear or shaky or mistracking, check the wheel alignment and balance right away.

3) In addition, it is recommended to do a four-wheel alignment when replacing new tires.

4) Quad wheel alignment check can also be carried out every time the tire is rotated.

Summary. Hello, I'm helping you sort out the answers to your questions, please wait a while Why do vehicles need to do four-wheel alignment and four-wheel balance.

Hello, I'm helping you sort out the answers to your questions, please wait a while Why do vehicles need to do four-wheel alignment and four-wheel balance.

Hello, according to the problem you described, what is to do a quad wheel alignment? To prevent the wheels from eating tires or running off. If you don't do dynamic balancing, it is easy to shake.

That four wheels are balanced.

If the dynamic balance is not done, it is easy to shake the wheels and shake the steering wheel.

Replacement standards for manual transmissions and their operating procedures.

This one is not clear.

Brake fluid spark plugs, replacement standards and their operating procedures.

Replace the original parts.

If the tire system is replaced or repaired, it is necessary to do dynamic balancing, and if the shock absorption and steering system are replaced, it is necessary to do 4-wheel alignment. In this way, the car can be driven better.

When the car deviates, these two maintenance needs to be done.

When the car deviates, you should consider doing a 4-wheel alignment, and the second is that when the tires have some very serious wear and tear, you should also do a balance.

At high speeds, if the body shakes a lot and there is a deviation, it is necessary to do dynamic balancing and 4-wheel alignment.

The role of car wheel alignment:

1. The tires benefit greatly, and after the four-wheel alignment, the tires can maintain the best angle with the car body, which improves the grip and ensures the comfort;

2. Improve handling, after the four-wheel alignment adjustment, the driving handling can be guaranteed accordingly;

3. The fuel saving effect is good, after the adjustment of the four-wheel alignment, the vehicle can drive according to the correct trajectory, which reduces the wind resistance to a certain extent, and the fuel consumption will also be reduced with the excitement of the family.

Under what circumstances do you need to do four-wheel alignment:

1. The driving performance of the car has been affected (the most direct feeling of the driver is that it deviates, and the direction is not automatically returned);

2. Damage to the chassis and suspension caused by accidents;

3. Abnormal tire wear (but also consider whether it is due to abnormal tire pressure that causes abnormal wear, under normal circumstances, high tire pressure will aggravate the wear of the tread, and low tire pressure will aggravate the wear on both sides of the tread; If there is eccentricity on one side, it is possible that the camber angle is misaligned);

4. The axle and suspension parts have been removed.

<> "Four-wheel alignment can ensure that the car runs in a straight line and ensures driving safety, but four-wheel alignment does not belong to the maintenance items of the vehicle. So when will the car do wheel alignment?

When the driver is driving, he finds that the steering wheel has a slight shake or feels too heavy and too light, then he needs to do four-wheel alignment.

When the driver is driving, the steering wheel is aligned, but the car has been misaligned, and then it is necessary to do four-wheel alignment.

When the chassis parts of the car are replaced, such as the steering tie rod or the suspension, it is necessary to do four-wheel alignment.

When the vehicle drives a certain number of kilometers and the tires have abnormal wear and tear, if the wear of a tire is inconsistent with that of other tires, it is also necessary to do four-wheel alignment at this time.

When the vehicle has the above problems, it can do four-wheel alignment, but it can not be done at will, and it is not accurate, which will change the original coefficient of each part of the vehicle, which will have a certain impact on the stability of the vehicle, and may lead to the development of accidents.
