Will the hub be hot under normal circumstances?

Will the hub be hot under normal circumstances? Under normal circumstances, the hub will not heat up. For example, the brake pads and tires will heat up after the vehicle is driven for a long time. The hub is the rotating part of the wheel core of the tire inner contour wheel steel connected by the column, and it is a metal part that supports the tire center and is installed on the shaft. Also called rims, rims, wheels and tire bells. The hub has information about size, width, PCD and hole position, offset and central hole. The causes of hot wheels are: 1, friction: the heat generated by tires rubbing the ground for a long time; High temperature caused by long-term braking and brake pad friction; 2. Oil leakage: the brake cylinder or brake pipeline leaks oil. Under normal circumstances, the hub will not heat up. If the vehicle runs for a long time, the brake pads and tires will heat up. Causes of fever of wheels, brake pads and tires: 1. Braking causes its temperature to rise: as we all know, cars brake by friction between brake pads and calipers. The higher the vehicle speed and load, the higher the heat generated during braking. This is also why the tires and brakes of large trucks are easy to smoke after getting off the high speed. 2 @20 19
