The quality of any part of the object itself is different. Under static and low-speed rotation, the uneven quality will affect the stability of the rotation of the object. The higher the rotation speed, the greater the vibration. As we all know, with the improvement of road conditions in China and the rapid development of automobile technology, the speed of vehicles is getting faster and faster. If the quality of the car wheel is not uniform, in this high-speed driving process, not only will the ride comfort be affected, but also the abnormal wear of the car tire and the suspension system will be increased, and the difficulty of controlling the car during driving will be increased, resulting in driving. Unstable.
In order to avoid this, the wheel is subjected to dynamic balance testing by a special equipment-wheel balance machine before installation, and the appropriate weight is added to the wheel mass to make the wheel maintain dynamic balance under high-speed rotation. The counterweight is the wheel balancer.
China's current car balance block standard-setting system is still a system of the planned economy era. This makes companies that have mastered a lot of new product information and technology actually lack a say in standard setting, especially on the issue of stainless steel car balance blocks. About the counterfeit and inferior car balance block brings great hidden dangers to the industry. The situation of lead-type car balance blocks is quite confusing and serious. At present, the top three manufacturers in the industry account for 65%-70% of the production of car balance blocks, and the top 10 manufacturers account for 90% of the total, but the products of these manufacturers Basically sold abroad, or to the domestic car factory. These manufacturers account for about 50% of the domestic retail market. The quality of these products is basically guaranteed, but 50% of the products in the domestic retail market are mostly from Wuzhou, Hebei and Zhuji, Zhejiang. These products are cheap but not produced to standard. The car balance block is small, but it is a requirement. The quality of the product is not good and it is very easy to cause an accident. This is also an issue that the industry needs to solve.
