How Does the Steering Wheel Control the Direction?
1 Answers
Steering wheel control principle: The steering wheel is sequentially connected to the steering column, steering drive shaft, steering gear, steering arm, steering drag link, steering knuckle arm, and steering tie rod below it. When the steering wheel is turned, it drives the rotation of the steering column and steering drive shaft. This torque is input into the steering gear, amplified and decelerated, then transmitted to the steering arm. From there, it passes through the steering drag link to the steering knuckle arm and tie rod, causing both wheels to turn at a certain angle simultaneously. This is the basic steering principle. In reality, to reduce the force required by the driver to operate the steering wheel, vehicles are equipped with a specialized power steering system. Additionally, the front wheels are not installed straight on the front axle but have certain deflection angles, including toe-in, kingpin inclination, caster angle, and camber angle.
