[0002] With the improvement of my country's road conditions and the rapid development of automobile technology, the speed of vehicles is getting faster and faster. If the quality of the car wheels is uneven, it will not only affect the comfort of the ride during high-speed driving, but also increase the abnormal wear of the car tires and suspension system, increase the difficulty of controlling the car during driving, and lead to unsafe driving. In order to avoid this situation, the wheels must be tested for dynamic balance by special equipment - wheel dynamic balancing machine before installation. Appropriate counterweights are added to the parts where the wheel mass is relatively small to keep the wheel in dynamic balance under high-speed rotation. This counterweight is the wheel balance block.
