Often customers bring cars to check periodically, the car has been used for a long time, the distance is quite far and less attention to the weight of the wheel / pressure for the vehicles.
Why on the wheel rim, aluminum of automobile wheels, there are the pieces of iron (many pastries, little pastries), the inner edge of each wheel clamps a cylindrical piece of iron?
Effect wheel balancing by the process of manufacturing wheels of wheels, the accuracy is not absolute, like tires. When a combination of 2 details is added, it causes a cumulative error. This error will cause dynamic imbalance when the wheel works. Therefore, when assembling the wheel assembly, people often put it into the machine to check the dynamic stability of the wheel assembly. The iron piece works to balance when the wheels work.
If this work is not done periodically (usually once every 3 months), when the car is traveling at high speed, there is often a strong shaking phenomenon, fast gear reversal, so that it can wear rotuyn and the handlebar size is long .
These tasks are all done by machines so it can guarantee absolute accuracy. So the garage, Toyota, Honda, Hyundai ... must buy and equip the device called wheel balancing device with lead weight tray.
Dynamic balance is checked on a tray weighing machine that can sense at least 5 grams of weight difference around the wheel. Why should we care about 5 grams of small deviations on a wheel with more than 10kg? That's because when the car moves, the wheel can spin around the shaft at speeds up to hundreds of times per minute. The uneven 5 grams will create a certain vibration.
When all four wheels have this vibration, it will cause the vehicle to vibrate causing a hot (explosive) tire and irregular wear. In addition, the wheel imbalance also causes damage to the vehicle's suspension, bearing system ....
To Tire Balance, the technician will set a certain weight to compensate for the missing weight at specific points.
