[0002] The wheel hub is a cylindrical metal part that supports the tire on the axle. It is also called a wheel rim, a steel ring, a hub, and a tire bell. The wheel hub has many types according to its diameter, width, molding method, and material. The magnetic steel, also known as a counterweight, is a weight installed on the wheel to balance the uneven mass of the wheel, reducing vibration and shaking at high speed. The wheel hub usually has a magnetic steel on its inner side, which maintains the dynamic balance of the wheel and ensures the stability and comfort of the vehicle at high speed. Specifically, the magnetic steel in the wheel hub has the following functions: (1) maintaining dynamic balance: any object rotating at high speed will cause vibration and imbalance due to uneven mass. The magnetic steel increases or decreases the mass distribution of the wheel, maintaining the balance of the wheel at high speed, reducing vibration and noise. (2) improving driving experience: an unbalanced wheel will cause the vehicle to shake, sway, and vibrate, affecting the stability and comfort of driving. The use of magnetic steel can effectively reduce these phenomena and improve the driving experience. (3) prolonging the life of the tire: an unbalanced wheel will increase the wear of the tire and shorten its service life. By using the magnetic steel for dynamic balance adjustment, the abnormal wear of the tire can be reduced, and its service life can be prolonged.
