What does dynamic balance mean?
2 Answers
Dynamic balance refers to the ability of a car's tires to maintain a relatively stable state when rotating at high speeds, ensuring normal driving. When the dynamic balance of tires fails, it can cause severe bumps, abnormal vibrations, increased fuel consumption, and abnormal tire wear during driving. This can shorten the tire's lifespan and even threaten driving safety. The principle of dynamic balance is mainly achieved through a dynamic balancing machine. The motor drives the tire to rotate, and due to the presence of unbalanced parameters in the tire, the centrifugal force exerted on the piezoelectric sensors in various directions is converted into electrical signals. By continuously measuring this signal and analyzing it through a computer system, the magnitude of the imbalance and the minimum parameter position are calculated and displayed. Finally, manual or auxiliary devices add or remove weight at the corresponding positions to achieve dynamic balance.
When I first started driving, I didn't understand wheel balancing well. Once on the highway, the steering wheel shook violently, which scared me into rushing to a repair shop. The mechanic said it was due to unbalanced tires and fixed it by adding lead weights, making it stable again. Wheel balancing refers to maintaining even weight distribution when the tires rotate to avoid vibrations caused by imbalance. This not only affects ride comfort but can also lead to abnormal tire wear, increased fuel consumption, and even damage to the wheel hubs or suspension. Every time I get new tires, after a tire repair, or when I feel vibrations after driving tens of thousands of kilometers, I recommend getting it checked. The repair process is simple and inexpensive—just a few minutes of testing with a machine—so don't delay. Saving a little money now might cost you big on repairs later.
