The steering wheel is the driver¡¯s primary interface with the vehicle¡¯s steering system. When the driver turns the steering wheel, it initiates movement within the steering column.

2. The Steering Column

The steering column transmits the rotational force from the steering wheel to the pinion gear. It acts as a bridge, ensuring that the driver¡¯s input is accurately transferred to the steering mechanism.

3. The Pinion Gear

The pinion gear is a small gear connected to the end of the steering column. When the driver turns the steering wheel, the pinion gear rotates, engaging the rack¡¯s teeth and converting rotational motion into linear motion.

4. The Rack

The rack is a linear gear that moves horizontally when engaged by the pinion gear. This movement directly influences the position of the front wheels, guiding the vehicle¡¯s direction.

5. The Tie Rods

The tie rods connect the rack to the steering knuckles of the front wheels. As the rack moves, it pushes or pulls the tie rods, which in turn steer the wheels left or right.

6. The Steering Knuckles

The steering knuckles are the pivot points between the wheels and the suspension system. They allow the wheels to turn and align with the driver¡¯s input.

7. Turning the Wheels

As the steering knuckles pivot, they turn the front wheels in the desired direction, enabling the vehicle to navigate turns and curves smoothly.

8. Power Steering

In modern vehicles, power steering assists the driver by reducing the effort required to turn the steering wheel. This system uses hydraulic or electric power to amplify the driver¡¯s input.
