How to do wheel dynamic balancing
Wheel dynamic balancing is an important part of vehicle maintenance. It can effectively prevent vehicle vibration and abnormal tire wear while driving. Recently, among the hot topics about car maintenance on the Internet, the attention of wheel dynamic balancing has increased significantly, especially among novice drivers and long-distance driving enthusiasts. This article will introduce in detail the steps, tools and precautions for wheel balancing to help you master this skill easily.
1. The function of wheel dynamic balancing
The main function of wheel dynamic balancing is to eliminate the centrifugal force caused by uneven mass distribution when the wheel rotates at high speed. If the wheels are unbalanced, it can cause the following problems:
| question | performance |
|---|---|
| Steering wheel shakes | This is especially obvious when the vehicle speed reaches 60-80km/h. |
| Abnormal tire wear | Increased local tire wear and shortened service life |
| Suspension system damaged | Long-term imbalance can cause suspension components to become loose or deformed. |
2. Tool preparation for wheel dynamic balancing
Before performing wheel dynamic balancing, you need to prepare the following tools:
| Tool name | Purpose |
|---|---|
| Dynamic balancing machine | Detect wheel imbalance position and value |
| balance weight | Glue or clip onto wheel hub to adjust balance |
| Jack | Lift the vehicle to remove the tires |
| wrench | Remove tire screws |
3. Steps of wheel dynamic balancing
The following are the specific steps for wheel dynamic balancing:
| steps | Operating Instructions |
|---|---|
| 1. Remove the tire | Use a jack to lift the vehicle and remove the tires that need balancing |
| 2. Clean the wheel hub | Clean the dirt and old balance weights from the wheel hub to make sure the surface is clean |
| 3. Install tires | Install the tire on the dynamic balancing machine and secure it firmly |
| 4. Enter parameters | Input parameters such as hub diameter and width on the dynamic balancing machine |
| 5. Start detection | Start the dynamic balancing machine and detect the unbalanced position and value |
| 6. Add balance weights | Follow the prompts to add a balance weight to the inside or outside of the wheel hub. |
| 7. Re-examination | Start the dynamic balancing machine again to confirm that the wheel has reached a balanced state |
| 8. Install tires | Reinstall the tire to the vehicle and tighten the screws |
4. Precautions for wheel dynamic balancing
When performing wheel dynamic balancing, you need to pay attention to the following points:
| Things to note | Description |
|---|---|
| Regular inspection | It is recommended to perform dynamic balancing every 10,000 kilometers or when replacing tires. |
| Choose professional equipment | Use high-precision dynamic balancing machines to ensure accurate test results |
| Balance weight type | Choose adhesive or clip-on balance weight according to wheel hub material |
| Avoid driving at high speeds | If the steering wheel is found to be shaking, check the dynamic balance in time |
5. Frequently Asked Questions
The following are frequently asked questions and answers about wheel balancing:
| question | Answer |
|---|---|
| The difference between dynamic balancing and four-wheel alignment | Dynamic balancing is to adjust the wheel mass distribution, and four-wheel alignment is to adjust the wheel angle. |
| Dynamic balancing price | The price of single wheel dynamic balancing is usually between 20-50 yuan, depending on the region. |
| Do all four wheels need to be dynamically balanced? | It is recommended to do this on all four wheels, especially when changing tires or noticing vibrations |
Through the above steps and precautions, you can easily complete wheel balancing to ensure driving safety and comfort. If you are not familiar with the operation, it is recommended to go to a professional repair shop for processing.
