What is dynamic balance

carThe wheels are made oftire,Wheel hubConstitute a whole. However, due to manufacturing reasons, the mass distribution of each part of the whole cannot be very uniform.What is dynamic balance,When the wheels of a car rotate at a high speed, it will form a dynamic unbalanced state, causing the wheels to shake,steering wheelThe phenomenon of vibration. In order to avoid this phenomenon or eliminate this phenomenon that has occurred, it is necessary to increase the counterweight of the wheel in a dynamic situation, so that the wheel can correct the balance of each edge part. This correction process is what people often call dynamic balance.

Why is there an imbalance In fact, when a new car leaves the factory, it has already been dynamically balanced, but we often go on bad roads, and it is very likely that the wheels will be broken.tireOne layer is rubbed off, and over time, it becomes unbalanced. Most tire repairs will remove the tire from the wheel hub. Generally, the normal process, as long as the tire has been removed, it must be dynamically balanced; in addition, if the tire or hub has been changed, the internal or external tire pressure has been installed. In theory, monitoring is all dynamic balance to be done. The effect of wheel imbalance If the tires are not in a balanced state when rolling, they can be felt when driving. The main feeling is that the wheels will jump regularly, which is reflected in the car as steering wheel shaking, although the phenomenon of steering wheel shaking may also be other factors. However, it is recommended to check the dynamic balance first when the steering wheel shakes. This probability is relatively high. In addition, the vehicle will resonate at a certain speed. In short, it will be uncomfortable for people with obsessive-compulsive disorder. In addition to the pulsation of the people in the car, the wheel imbalance can also damage the car itself to a certain extent. Long-term driving of a vehicle with serious wheel imbalance (generally, the weight of the imbalance is more than 50g is more serious), then it also has an impact on the life of the bearing, and a long time will cause bearing strain. In addition, when the imbalance is serious, the tires may also wear out due to abnormal lateral swing, and the tire life will also be affected. In short, the impact of wheel imbalance on the vehicle itself is not worth the gain. Steps to do dynamic balance Before doing dynamic balancing, first need to remove the original counterweight and use a special dynamicBalancing machineMeasure the wheel weight distribution, and then add a suitable weight to the corresponding position. The adjustment of dynamic balance is relatively easy to achieve. Most 4S stores can provide this service, and all major brand tire service stations can also do this service. In addition, some brand car shops have such fast Repair service. Of course, the prices for dynamic balance in these places are different, you can buy them according to your actual situation.
