What is the metal piece inside the wheel hub?
1 Answers
The metal piece inside the wheel hub is a tire balancing weight. Here is the relevant introduction about tire balancing weights: 1. Tire unevenness: The car's wheel is a whole composed of the tire and the wheel hub. However, due to manufacturing reasons, the mass distribution of each part of this whole cannot be very uniform. 2. Rotational imbalance: When the car wheel rotates at high speed, it will form a dynamic imbalance state, causing the wheel to shake and the steering wheel to vibrate while driving. To avoid this phenomenon or eliminate an already occurring phenomenon, it is necessary to correct the balance of each edge part of the wheel by adding counterweights under dynamic conditions.
