Some knowledge about automobile dynamic balance

The dynamic balance data is poor, and there are many balance blocks. In addition to the poor dynamic balance data, the balance weight also fell off

There are two types of balance weights, the plug-in type and the paste type

Dynamic balance data is perfect

Many car owners will ask, why do tire repairs and tire replacements require dynamic balancing?

First of all, the wheel is a whole composed of tires and hubs. However, due to the manufacturing process and materials, the mass distribution of each part of the whole wheel cannot be completely uniform. For example, the tire has the most important and lightest points.

Wheels with uneven mass distribution will be unstable when they turn, and vibrations will cause the steering wheel to vibrate and other problems, especially when rotating at high speeds (for example, the fan will be unstable if there is one less leaf). Dynamic balance is to make the mass distribution of the wheel as uniform as possible by adding counterweights, which is also the working principle of dynamic balance. New cars are usually dynamically balanced when they leave the factory. When tires are repaired or replaced, the original dynamic balance is destroyed (the mass distribution of the wheels is destroyed), so it needs to be done again.

In fact, in addition to tire repair and tire replacement, when the wheels are hit, the vehicle deviates, the balance weight falls off, the wheel hub is replaced, and the tire pressure monitoring is installed, etc., it is necessary to re-balance the dynamics to ensure that the wheels are in good condition and extend the life of the tire.
