Dynamic balance

times   2016-12-07

In the vehicle factory assembly, will do the dynamic balance test, is to make the wheels more stable high-speed. What is dynamic balancing? What should we do?

The wheel of an automobile is a whole made up of tire and wheel. However, due to manufacturing reasons, so that the overall quality of the various parts of the distribution can not be very uniform. When the car wheels rotate at high speed, it will form a dynamic imbalance, causing the vehicle in motion wheel jitter, steering wheel vibration phenomenon. To avoid this phenomenon or to eliminate this phenomenon has occurred, it is necessary to make the wheels under dynamic conditions by increasing the weight of the method, so that the wheel alignment of the edge of the balance. This correction process is often said that the dynamic balance.

Do the steps of balancing

 1. Steps to do the balancing: the wheel mounted on the dynamic balance, select the size of the fixation device. First, pull the ruler out of the balancing machine, measure, and then enter the first controller.

2. Then take out the bend rule and measure the rim width, as well as the second controller.

3. At the controller input rim diameter, press STRAR to start.

When the test is stopped, the computer will measure the weight inside and outside the rim need to increase the weight, first installed outside, turn the tire, according to the tips of the weight beat.

 The dynamic balance is for a single tire, the purpose is to make the tire itself does not occur when the rotation center of gravity deflection. Balance as long as the tire removed, the dynamic balancing machine, turn, look at the value displayed by the machine.

4. At the same time on both sides of the wheel and knock on the value of the weight of the corresponding weight (a buckle of small tin, marked above the weight), but note that, such as left and right respectively show 10,15, The weight of 10 and 15 were knocked on the two balance blocks, and not only in the right side of a weight of 5 weight balance, it is less than the required.

Tires should be regularly done balancing test, check with a dynamic balance detector. Tire balance is divided into two kinds of dynamic balance and static balance. Dynamic imbalance will cause the wheels to swing, so that tires produce wave-type wear; static imbalance will produce bumps and jumping phenomenon, tend to flatten the phenomenon of the tire. Therefore, the regular detection of balance not only can extend the tire life, but also improve the stability of the vehicle when driving, to avoid high-speed driving due to tire swing, beating, loss of control caused by traffic accidents.
