How is the force analysis of the steering wheel conducted?

[VonPhoebe]

It is subjected to friction and corresponding resistance. The principle of the steering wheel: When the driver starts to turn the steering wheel, the tires actually rotate around the kingpin as the center. However, this rotation is not parallel to the ground, so part of the wheel should theoretically sink into the ground, which is impossible. Ultimately, the ground's reaction force on the tire will slightly lift the front of the car. Under the car's own gravity, the wheels will return to a position parallel to the direction of travel, making the steering wheel easier to return to center. Interaction of forces: Since forces are mutual, the lateral reaction force of the road surface on the wheels will form a moment around the kingpin axis that is exactly opposite to the direction of wheel deflection, generally called the stabilizing moment. As a result, the wheels will return to their original position and resume stable straight-line driving.
