What is Wheel Alignment? What is a quad alignment?

To put it simply, wheel alignment is to adjust the position of the various parts of the chassis of the car to restore them to their factory settings.

Since the installation between the four wheels, steering mechanism, and front and rear axles of the vehicle should have a certain relative position, this relative position is the standard value set by the manufacturer, if deviation occurs, the car will have a variety of fault problems.

The installation of adjusting and restoring this position is the four-wheel alignment, which can ensure the vehicle's straightness, driving stability and automatic steering return to the center, etc., and reduce tire wear and extend service life.

The installation between the steering wheel, the steering knuckle and the front axle of the car has a certain relative position, and this 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.

Tire benefits: Since it is called four-wheel alignment, it must be a very big benefit to 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.

Improved handling: Keeping the tires in normal condition is of course very good 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.

Fuel saving: It is obvious that fuel consumption decreases as the rolling coefficient of friction decreases 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.

Safety guarantee: If the tires are good, the safety will be greatly improved. In fact, after the four-wheel alignment adjustment, the maintenance technician will also check the condition of the suspension system and other components of the car, 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.

1. The function of automobile four-wheel alignment is:

It is conducive to the car to maintain a stable straight line and light steering, and reduce the wear and tear of tires and steering parts during driving.

2. Under what circumstances do you need to do four-wheel alignment?

When driving the vehicle, you feel that the direction of the steering is heavy, shivering, misaligned, not homecoming, or you find that the tires are unilaterally worn, corrugated worn, block worn, eccentric wear and other abnormal wear and tear, as well as when driving, the car feels floating, trembling, swaying and other phenomena, you should do four-wheel alignment.

1) Tire pressure and tire tread wear: Uneven tire wear indicates a failure in certain aspects such as tires, steering or suspension. (There are many reasons why tires wear out irregularly and wear out too quickly.)

The most common reasons are improper inflation pressure, not regularly changing tires, improper driving habits, or incorrect alignment of the original four wheels. )

2) Wheel oscillation: Oscillation is a condition that causes unstable rotation of tires due to various reasons, and the oscillation of wheels and tires refers to irregular up-and-down or side-to-side movements. Left-right motion refers to the lateral oscillation of the wheel or tire, and up-down motion refers to the radial oscillation of the wheel or tire.

Vibration faults related to the oscillation can only be eliminated by looking for the ** of the oscillation.

3) Wheel deviation: Deviation refers to the deviation of the vehicle driving direction when the vehicle is driving on a straight road, and the steering wheel is not affected by any external force. Mistracking is usually caused by:

Tire structure (radial transverse force).

Improper fit or uneven wear of the tires.

Improper alignment of the front or rear wheels.

The steering valve is off-center.

Uneven brake adjustment or brake lag.

Since the installation between the car tires, steering mechanism and front and rear axles should have a certain angle and relative position, correct the angle and position between the chassis tire parts, which is the four-wheel alignment.

Four-wheel alignment is based on the vehicle's four-wheel parameters, which are adjusted to ensure good driving performance and certain reliability.

The front wheel alignment includes four contents: kingpin camber (angle), kingpin camber (angle), front wheel camber (angle) and front wheel toe. Rear-wheel alignment includes wheel camber and rear-by-wheel toe-in. In this way, the front wheel alignment and rear wheel alignment are collectively called wheel alignment, which is often referred to as four-wheel alignment.

The function of 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.

A certain relative position between the installation of chassis objects such as automobile wheels, shock absorption, and steering tie rods, and the installation of this relative position is called four-wheel alignment. To put it simply, there is a certain distance between the chassis objects, and the control between this distance is the so-called four-wheel alignment. Note!

Wheel alignment is not a maintenance item, but a means of maintenance, so the car generally has nothing to do with the wheel alignment.

What else can I do, continue to repair, is this warranty? If it is at your own expense, it is recommended that you can change to a 4S store, or change to a master.

Wheel alignment is an indispensable maintenance in car maintenance. If the car is driven in bad road conditions for a long time, or when the tire and chassis collide, the parameters of the four-wheel alignment will be inaccurate, affecting the driving of the car.

Because the installation of automobile tires, steering mechanisms and front and rear axles should have a certain angle and relative position, the angle and position between the chassis tire parts should be corrected, which is the four-wheel alignment.

Four-wheel alignment function.

The function of the four-wheel pair is to keep the car running in a straight line and smooth without deviation; Maintain the best angle with the fetus and will not eat the fetus; Reduces wear and tear between tires and steering components during driving.

Keeping your tires in good condition is great for driving safety. After the four-wheel alignment is adjusted, the driving maneuverability can be guaranteed accordingly. Moreover, after the four-wheel alignment is adjusted, the vehicle can follow the correct trajectory, which reduces wind resistance and fuel consumption to a certain extent.

Combined with the standard tire pressure value, the tire can not only maintain the best grip effect, but also minimize the friction between the tire and the ground, and extend the service life of the wheel book.

What do I need to do for wheel alignment? 1.When driving, the car is obviously driving in a straight line, but the steering wheel is crooked, or you feel that the direction is turning heavier, shaking, and not returning to the right position, etc. , which requires four-wheel alignment;

2.Abnormal tire wear, abnormal wear such as wavy wear, block wear or eccentric wear on one side of the tire, which requires four-wheel alignment;

3.Driving a car will have the feeling of floating, bouncing, guessing dates, swaying, etc. , which requires four-wheel alignment.

How often is wheel alignment done?

Under normal circumstances, the car travels about 10,000 kilometers a year, and you can choose to do four-wheel Zhaoxun positioning. However, the exact time depends on how often the car is used. If it is a taxi, it should be done every six months because the frequency of use is too high.

To do four-wheel alignment, find a regular, professional, technical support repair shop or 4S shop, which is safer.

Millions of car purchase subsidies.

Since the car tires, the steering machine Yang and the valence axle installed between the axle should have a certain angle and relative position, correct the angle and position between the bottom tire parts, which is the four-wheel alignment.

I found that there is an interesting phenomenon in the car rim, that is, many old drivers have some misunderstandings when driving, which indirectly leads to the understanding of some novice drivers for vehicle failures has also deviated, the biggest misunderstanding is the four-wheel alignment and dynamic balance, many novice drivers generally think that as long as the vehicle chassis is uncomfortable, the first thing that comes to mind is to do four-wheel alignment, in fact, this is a very big misunderstanding, this topic we will focus on four-wheel alignment and dynamic balance, to talk about the functions and roles of the two in detail.

High-speed jitter dynamic balance, the vehicle deviates and eats tires to do four-wheel alignment.

First of all, we must emphasize to you that four-wheel alignment and dynamic balance is not omnipotent, we must clearly know the cause of our vehicle failure before doing four-wheel alignment and dynamic balancing, and we must do the right medicine, otherwise it will be in vain.

1. Dynamic balance, the main function of dynamic balance is to balance both sides of the tire, so that when the tire is driving at high speed, the tire will not cause the entire body to swing because of the violent swing, under normal circumstances, as long as the tire of our vehicle is disassembled, the dynamic balance must be done, because the tire is not a uniform circle in the production process, if the vehicle travels to 80km h, the vehicle shakes violently, then it can basically be concluded that the dynamic balance data is too large.

2, four-wheel alignment, four-wheel alignment is more professional, four-wheel alignment involves the adjustment of the entire vehicle chassis, generally speaking, long-term driving in poor road conditions of the vehicle, the chassis will inevitably loosen the situation, at this time the chassis data error in all aspects will become larger, and these changes in the data directly reflect the situation is the vehicle deviation and tires eat tires, as long as the vehicle appears in such a situation, it must be immediately done four-wheel alignment.

There is a big difference between a vehicle mistracking and a tire eating a tire!

1. Vehicle deviation, in fact, vehicle deviation is divided into two situations, one is the steering wheel is crooked, and the other is the vehicle is crooked, everyone must learn to distinguish.

A crooked steering wheel is when the steering wheel of a vehicle deviates slightly at an angle, but the vehicle can stay in a straight line at that angle.

Crooked vehicle refers to the situation in which the steering wheel position is kept in the center, and the vehicle involuntarily looks at the left and right sides.

Under normal circumstances, the deviation only needs to adjust the ball head of the external tie rod on the steering machine, and the effect is very good with the data on the four-wheel positioning computer.

At this time, the first thing we need to adjust is the camber angle of the vehicle, generally starting from the rear suspension of the vehicle chassis, adjusting the inclination angle of the rear suspension after adjusting the rear suspension, and then adjusting the inclination angle of the front wheel and the toe, if the data error is relatively large, you may also need to use eccentric screws to adjust.

To sum up, when drivers find that there is a problem with the vehicle chassis, they must communicate clearly with the auto repair shop, first determine whether there is a problem with the vehicle chassis, and then they can do four-wheel alignment calibration, otherwise it is useless and cannot solve the problem in the real sense.

Four-wheel alignment refers to the adjustment of the four wheels of the car, turn into the organization, the installation and use of the front and rear left and right drive shafts should have the relative position and perspective, which is required by the manufacturer, and if the car is driven for a long time under the condition of poor real-time road conditions or tires, the chassis of the car is bumped and bumped, this relative position will be inaccurate, and the car will suffer from harm, it is necessary to carry out four-wheel alignment.

The effect of four-wheel alignment is that it can also make the car run in a parallel line for a long time, which is not easy to deviate from the direction and ensure safe driving; The tires maintain a better viewing angle with the body, and it is not easy to eat tires; Reduce the wear and tear between the tires and the rotating parts during the whole driving process of the car, and increase the service life of the tires.

The tires are in good condition, which is very good for safe driving. After the four-wheel alignment adjustment, safe driving maneuverability can be guaranteed. And, after the adjustment of the four-wheel alignment, the car can drive according to the reasonable movement trajectory, reduce the air resistance at a certain level, and the fuel consumption will also be reduced, and then cooperate with each other to standardize the tire pressure value of the car, the tire can not only ensure the best grip effect, but also minimize the friction between the tire and the road surface, and increase the service life of the tire.

Wheel alignment is necessary when:

1. When driving the car safely, the car is running parallel lines, but the steering wheel of the car is crooked, or it feels that the azimuth rotation is heavy, trembling, not returning, etc., which is also necessary to do four-wheel alignment;

2. Abnormal tire wear, wavy wear, small piece wear or eccentric wear on one side of the tire, must do four-wheel alignment;

3. When driving the car safely, it is necessary to do four-wheel alignment if it feels suspended, jolting, swinging, etc.

4. Overhaul or replace the suspension and automobile steering system, and also need to do four-wheel alignment.

Under normal circumstances, the car can be selected to do four-wheel alignment after driving 10,000 kilometers or every year. However, the exact time depends on the frequency of the car's application. If it is a taxi, because the number of car applications is too high, it needs to be inspected every six months.

To do four-wheel alignment, you should find a reliable, technically professional, and technically guaranteed auto repair shop or automobile 4S shop to do it, which is more secure.
