The principle of wheel weights
Every part of the mass of any object will be different, in the static and low-speed rotation, the uneven mass will affect the stability of the object rotation, the higher the speed, the greater the vibration will be. The role of the balance block is to let the wheel quality gap as close as possible to achieve a state of relative balance.
Research and development background of wheel weights
Along with our country highway condition improvement and the automobile technical level development is rapid, the vehicle traveling speed is also more and more fast. If the quality of the automobile wheel is not uniform, it will not only affect the ride comfort, but also increase the abnormal wear of the automobile tire and suspension system, increase the difficulty of vehicle control in the course of driving, resulting in unsafe driving. In order to avoid this situation, the wheel must pass through the special equipment-the wheel dynamic balance machine to carry on the dynamic balance test before the wheel is installed, make the wheel in high-speed rotation to maintain dynamic balance, this weight is the wheel balance.
Main function
Because the driving mode of the car is usually the front wheel, and the front wheel load is greater than the rear wheel, after a certain mileage of the car, there will be differences in the degree of fatigue and wear of the tires at different parts of the car, therefore, it is recommended that you change your tires according to the mileage of your car or the road conditions. Due to the complicated road conditions, any situation on the road may have an impact on your tires and rims, such as collision with the road, high-speed through the Pothole Road, etc. , easy to cause deformation of the steel ring, so it is recommended that you do the tire dynamic balance in transposition at the same time.
The effect of installing the wheel weights on the balance result
wheel weight often has two forms, one is hook type, one is paste type. The clip-on wheel weight is arranged on the wheel flange of the tire, and the clip-on wheel weights is deformed and clamped on the wheel flange by knocking. The adhesive wheel weight is mounted on the inner side of the wheel rim using the pasting mounting method. As for the clip-on wheel weight, it is difficult to control the clamping force stably after assembly because it is installed by the way that the clip-on is deformed by percussion, and it is easy to fall off the balancing block in the course of driving. Therefore, in the production process, the need to pull out of the test into the control plan. As for the adhesive wheel weight, the cleanliness of its mounting surface will affect the pasting effect. Therefore, before the assembly, the need to wipe the wheel installation location, and suggest the use of isopropyl alcohol for cleaning, to be dry after the installation. After pasting, it is necessary to put pressure on the wheel weight and keep a certain length of time. For stability control, it is recommended that special equipment be used for this operation. At the same time, the installation position of the wheel weight needs to have a clear reference, to prevent the assembly of the greater deviation.
