What is the principle of steering wheel controlling the wheels?

[JoshuaFitz]

The steering wheel is connected to the steering shaft via splines. Its function is to convert the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft. The steering shaft controls the rotation of the front wheels. Whether the car is moving forward or reversing, the steering wheel controls the rotation of the front wheels through the rotating shaft, meaning it adjusts the direction of the car's front. Brief introduction: Below the steering wheel are sequentially connected the steering shaft, steering transmission shaft, steering gear, steering rocker arm, steering tie rod, steering knuckle arm, and steering tie rod. After turning the steering wheel, it drives the rotation of the steering shaft and steering transmission shaft, and this torque is input into the steering gear. Extended information: If the rear of the car needs to move to the right rear, turn the steering wheel to the right; conversely, if the rear of the car needs to move to the left rear, turn the steering wheel to the left.
