Why does the front wheel hub get hot?

[OCharlie]

There are two possible reasons for the high temperature of the front wheel hub: one is the wheel hub (axle head), and the other is the heat generated by the brake drum. The following is an introduction about the wheel hub: 1. Introduction: The wheel hub is the rotating part of the wheel core connected by the wheel steel inside the tire, which is the metal component that supports the tire and is mounted on the axle. It is also called the rim, steel ring, or wheel. Wheel hubs come in various types depending on diameter, width, forming method, and material. 2. Types of wheel hubs: The wheel hub is also called the rim. Depending on the characteristics and needs of different vehicle models, the surface treatment process of the wheel hub will also adopt different methods, which can be roughly divided into painting and electroplating. For ordinary vehicle models, the appearance of the wheel hub is less considered, and good heat dissipation is a basic requirement. The process basically uses painting treatment, that is, spraying first and then baking, which is cost-effective and has bright colors that last for a long time. Even if the vehicle is scrapped, the color of the wheel hub remains unchanged.
