What is the principle of dynamic balancing on a car

1. The reason why automobile tires need to be dynamically balanced is that they need to be dynamically balanced when replacing new tires or after tire disassembly and assembly. It is usually impossible to distribute the weight evenly 100% after the tire is mounted on the rim, use a balancing machine to test the balance of the tire rim in a sports situation, and use a balance weight counterweight at the unbalanced point to ensure that the tire can run smoothly and avoid shaking.

2. The meaning of dynamic balance is.

One of the studies of rotor dynamics is defined as determination.

The operation of eliminating the position and magnitude of the unbalance (centrifugal force and centrifugal force, see Relative Motion) generated by the rotation of the rotor. The amount of unbalance causes lateral vibrations of the rotor and subjectes the rotor to unnecessary dynamic loads, which is not conducive to the normal operation of the rotor. Therefore, most rotors should be dynamically balanced.

In machine manufacturing or maintenance, balancing becomes a process.

3. The specific meaning of dynamic balance may not directly cause tire eccentricity caused by dynamic balance, but the shake caused by long-term imbalance will affect suspension and other components. The balance is corrected on the two sides of the rotor at the same time, and the remaining unbalance after correction is carried out to ensure that the rotor is within the specified range of the allowable unbalance when it is dynamic, and the dynamic balance is also called double-sided balance.

This means that after the tire is installed on the wheel, the mass distribution on the whole wheel is not balanced, such as the valve, the pattern and markings on the tire, etc., due to manufacturing reasons.

When the tires rotate at high speed when the vehicle is moving, these insignificant mass deviations will cause the tires to shake during the vehicle, which will drive the steering wheel and even the entire body to vibrate. This vibration phenomenon usually occurs in the speed range of 90-120 km/h.

In order to solve this phenomenon, under normal circumstances, we can find the required weight and position of the counterweight of each tire through the method of tire dynamic balancing, and then at the edge of both ends of the wheel, find the required counterweight position, add the appropriate counterweight "lead block", so that the tire deviation does not exceed 5 grams, when the counterweight deviation exceeds 10 grams, there will be a corresponding vibration feeling in driving, and the dynamic balance of the tire will be completed.

The main advantage is poor silver.

1.Enhance driving comfort;

2.reduce gasoline consumption;

3.Increase the life of your tires.

4.Ensure the straight-ahead stability of the Tsai Qingxiao vehicle;

5.Reduce the wear and tear of chassis suspension accessories;

6.Enhance driving safety.

If it is necessary to do balancing.

1.After replacing a new tire or repairing it in a collision accident;

2.unilateral eccentric wear of front and rear tires;

3. The steering wheel is too heavy or floating and shaking when driving;

4.When driving straight, the car deviates to the left or right;

5.Although there is no such condition, for maintenance purposes, it is recommended that the new car should be driven for 3 months and then once every six months or 10,000 kilometers.

The wheels of a car are made up of tires and hubs. However, due to the reason of slag in manufacturing, the mass distribution of each part of the whole cannot be chained, and it can be very uniform.

When the wheels of the car are rotated at pure speed, a dynamic imbalance will be formed, resulting in the phenomenon of wheel shaking and steering wheel vibration during driving.

In order to avoid this phenomenon or to eliminate the phenomenon that has already occurred, it is necessary to make the wheel correct the balance of each edge part by increasing the counterweight in the dynamic situation. This process of correction is often referred to as dynamic equilibrium.

There are two types of tire balancing: dynamic balancing and static balancing.

Dynamic imbalance causes the wheels to sway, causing the tires to wear in waves. Static imbalance can cause bumps and runouts, often causing flat spots in the tires.

Therefore, checking the balance regularly not only prolongs the life of the tires, but also improves the stability of the car while driving.

I believe that many friends may not be so familiar with the word "dynamic balance". So, what exactly is balance? What would happen to the vehicle if it wasn't balanced? Is it dangerous? Let's talk about these questions today!

What is Balancing?

To put it more bluntly, dynamic balancing means that when the wheels are turning, the vehicle can still maintain a state of balance. And four-wheel alignment is not a concept. The difference between the two is that the dynamic balance is to adjust the balance, and the four-wheel alignment is the adjustment of the suspension parameters!

Why do we need to do balancing?

The reason why you do dynamic balancing is because the tires are not completely round. You may be puzzled by this. Actually, it's like this.

When the tires and rims are combined, it is difficult to achieve a balanced state due to structural limitations. There are many reasons for this, such as the distribution of valve and tire weight. In this way, the tires are not completely round, and deformation will occur.

Under what circumstances should I do balancing?

Change the tire, take the tire down and check it, as long as the tire and the rim are separated, you must do dynamic balancing.

In addition to this, the pay-off reel has jitter, steel ring deformation, tire repair, increase tire pressure monitoring module, valve replacement, the occurrence of these situations is likely to be related to the dynamic balance. Don't forget to check it out!

How to solve the problem of imbalance?

Some repair shops solve the problem of imbalance by possibly attaching weights to the tires. In fact, sticking a counterweight is not a particularly good way, but it is just a remedy. Because if there are too many counterweights, not only will the vehicle not balance, but the weight will rise, and the greater the inertia, the more the wheel shake.

If the tire on one side, with a 70-gram weight on it, has not yet reached a balanced state, then the repairman has to use another method!

If the lead trail fruit is knocked and beaten, it can round the wheel, which is the good skill of the repair master. If it doesn't work, spend money on a new set!

What is the effect of not balancing?

Without dynamic balancing, the tires will jump regularly during the driving of the vehicle, and the reaction to the cockpit is the shaking of the steering wheel. After driving to a certain speed, the vehicle develops a sense of "resonance". It's particularly uncomfortable to drive!

In the long run, the tire will be eccentric wear, and if it is serious, it will also have a lot of impact on the suspension and bearings!

The wheels of a car are made up of tires and hubs. However, due to the reasons of the system and the world, the mass distribution of the various parts of the whole cannot be very uniform. When the wheels of the car rotate at high speed, the sail limbs will form a dynamic imbalance, resulting in the phenomenon of the wheels shaking and the steering wheel vibrating during driving.

In order to avoid this phenomenon or to eliminate what has already occurred.

The dynamic balance of a car usually refers to the balance between the 4 wheels of the car during driving. Because the quality of the tires will not be particularly uniform after the tire is repaired, the balance of the tire will be adjusted by using the balance weight.

When the vehicle is running at high speed, the tires will be unbalanced, and this unbalanced force will be fed back to the steering wheel, causing the steering wheel to shake. Adding a counterweight to the tires solves this problem, resulting in better balance at high speeds.

The dynamic balance is for a single tire, and the main purpose is to make the tire not deflect the center of gravity when rotating, so as to ensure the dynamic balance of the vehicle. If the dynamic balance is adjusted well, we can increase driving comfort, reduce car fuel consumption, increase tire service life, ensure the stability of the vehicle, reduce the wear and tear of suspension accessories, and enhance driving safety. The dynamic balance of the tire is detected by a dynamic balancer, and the computer measures the weight of the weight that can be increased inside and outside the wheel.

Dynamic balance refers to the balance between the wheels in the process of running the vehicle, the reason why the balance weight is needed is because the mass distribution of each tire in the manufacture of the whole parts can not be very uniform, when the car wheels rotate at high speed, it will form a dynamic unbalance state, which will be reflected on the steering wheel of the car, and the steering wheel shakes or vibrates.

The steps to do balancing are:

1. Remove the logo and install the wheels on the dynamic balancer, choose the fixer that adapts to the size, pull out the ruler on the talking balance meter to measure, and enter the first controller;

2. Take out the rear curved ruler, measure the width of the rim, and also input it on the second controller;

3. Enter the rim diameter in the controller and press strand to start;

4. When the detection stops, the computer will measure the weight of the weight that needs to be increased on the inside and outside of the rim, install the outside first, and turn the wheel Sakura Min tire according to the weight of the lifting Songchang.

It is generally believed that the dynamic balance of a vehicle is the balance between the wheels of the vehicle when it is moving. It is commonly referred to as the addition of balance weights.

5.reduce the wear and tear of chassis suspension accessories;

6.Enhance driving safety.

The method of dynamic balancing of automobile tires is as follows:

Preparation materials: tires, dynamic balancing machines, calipers.

1. Put the tires on the dynamic balancing machine.

Fix it with a buckle, if the tire has an old balance weight, you need to put down the old balance weight first.

2. Measure the distance from the machine to the tire rim.

Enter the appropriate values on the machine.

3. Measure the width of the steel ring with a caliper.

Once the value is obtained, the data is entered into the machine.

4. Read the radius of the tire rim.

Usually there will be specifications on the tires, and you can enter the value in the machine.

5. Then press the start button on the machine.

At this time, the tire rotates, the tire deviation value will be displayed on the machine, manually rotate the tire, when the inside of the machine shows the full grid, you can add the balance weight of the phase permeable mask on the inside.

If the value is too large, you can use several balance weights to add up to get the displayed value, after the inner side is added, continue to rotate the tire by hand, wait for the outer side to be full, and then add the outer balance weight, press the start button on the machine again, the tire rotates, stops, Mach. The machine displays two 00 values, indicating that the dynamic balancing has been completed.

Balancing effect:

When doing dynamic balancing, the machine plexus liquid can detect which part of the wheel is lighter and the key is lighter, and then the technician can attach the weight to the lighter part, so that the weight of each part of the wheel is the same.

If the wheels are unusually shaking at high speeds, the car's handling and driving stability will suffer. And it can also cause the comfort of the car to suffer.
