What are the working principles of bike headset bearings?

In our previous life, as long as it is to travel that can not be separated from the bicycle, at that time the most famous bicycle ride, with four or five people that is no problem, until now many bicycles are basically not to talk about people, and riding for a period of time the car will be quack sound.Later, through the solution of the old master, I came to understand that there was something wrong with the bike headset bearings, so I had to remove the bad bike headset bearings and replace it with a new one.

What are the working principles of bike headset bearings?
Both front and rear wheel bearings rotate with outer rings, equivalent to double row angular contact ball bearings.
The rear wheel bike headset bearings mainly bears the rotating load;Front wheel bike headset bearings mainly bear fixed loads.
The bicycle is a chain drive. The foot pedal drives the front sprocket wheel and transfers it to the back sprocket wheel.The chain gives a torque to the rear wheel and drives the rear wheel to rotate.

The forward force gives a torque to the front wheel. The outer ring of the front wheel bearing rotates with the front wheel, and the steel ball rotates with revolution to move forward.
When turning, the front wheel bearing bears tilting torque on one side.
Because a safety clutch is installed on the bike headset bearing (consisting of star wheel, ball, spring, etc.), when pushing forward, a spring supports the ball to make the bike headset bearings and the gear chain run synchronously. When pushing backward, the spring is squeezed and shortened, and the ball moves backward.
