What is the reason for the car hub heating?

There are two sources of hub heating.

1. The heat generated by the tire rubbing on the ground for a long time is conducted to the wheel hub, resulting in an increase in the temperature of the wheel hub.

2. Even if the brake pad is braked for a long time, the friction of the brake pad will generate high temperature, which will be transmitted to the hub, leading to an increase in temperature.

Solution: Because hub fever is a normal phenomenon, you can pay attention to it at ordinary times and don't need to go to a repair shop.

Wheels on the market can be divided into steel wheels and alloy wheels according to their materials, each with its own advantages and disadvantages.

The main advantages of steel wheel hub are simple manufacturing process (generally casting process, for example, aluminum alloy wheel hub is generally produced by low-pressure casting process), relatively low cost and strong metal fatigue resistance, which is also commonly known as cheap and good quality.

However, the disadvantages of steel wheel hub are more prominent, such as ugly appearance (it can be said that there is no appearance at all), heavy weight (the same wheel hub steel material is much heavier than aluminum alloy material), large inertial resistance, poor heat dissipation and easy rusting.
