The balance block is the basic material used for wheel balance block correction. According to the fixed type of the balance block, it can be divided into two types: hook type and paste type. Among them, according to the quality, it is divided into several specifications of different sizes, including 5g, 10g, 15g, 20g, etc., and the gauge interval of the balance block is usually 5g. The adhesive weight is mainly used for the hub with no fixed hook on the edge, and the balance block is fixed to the inner wall of the hub through the high-strength double-sided adhesive on the back.
Not only the material of the wheel hub is divided into steel and aluminum alloys, but also the material of the balance block is different. At present, the texture of the balance block mainly includes iron, zinc and lead. In order to ensure that the balance block has the characteristics of environmental protection and anti-corrosion and aesthetics, many manufacturers need precision machining in the manufacturing process, and also carry out galvanizing, spray coating and even resin treatment on the surface of the balance block.
In order to avoid the occurrence of dangerous situations, the wheel is subjected to dynamic balance test by 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 weight is the wheel balance block.
