What is the Principle of Car Steering?

[ValeriaAnn]

Car steering principle is: By turning the steering wheel, the car transmits torque to the rack and pinion mechanism, thereby pushing the wheels to turn left or right. The longer the rack pushes, the greater the angle the tires turn. When the vehicle leans forward, the engine makes both wheels rotate forward to maintain balance; when the vehicle leans backward, the engine makes the wheels rotate backward. Simply put, the steering wheel can be understood as a lever, with the radius of the steering wheel being the length of the force arm. The larger the steering wheel, the less effort is required. Currently, the automotive market universally adopts power steering. By detecting the direction in which the driver turns the steering wheel and the vehicle speed, the power steering motor controls the amount of steering torque applied to achieve the steering function.
