The steering wheel is the primary input device used by the driver to provide steering inputs. When the steering wheel is turned, the steering column transmits the rotational motion to the steering rack. The steering rack, in turn, converts this rotational motion into linear motion, which is then transmitted to the tie rods. The tie rods are connected to the ball joints, which are then connected to the vehicle's wheels. As a result, the wheels are turned in the desired direction, causing the vehicle to change its direction.
The purpose of steering gear is to provide a convenient and efficient way for the driver to control the direction of the vehicle. It allows the driver to make precise adjustments to the vehicle's heading, even at high speeds, ensuring safe and controlled driving.
