It is actually a pretty simple mechanism.
Simple rack and pinion steering diagram.
This pinion runs in mesh with a rack that is connected to the steering tie rods.
A rack and pinion is commonly found in the steering mechanism of cars or other wheeled steered vehicles rack and pinion provides less mechanical advantage than other mechanisms such as recirculating ball but less backlash and greater feedback or steering feel the mechanism may be power assisted usually by hydraulic or electrical means.
A rack and pinion gearset is enclosed in a metal tube with each end of the rack protruding from the tube.
A rod called a tie rod connects to each end of the rack.
Rack and pinion steering is quickly becoming the most common type of steering on cars small trucks and suvs.

It also provides a gear reduction so turning the wheels is easier.
Working principle of rack and pinion steering gear.
Rack and pinion steering uses a gear set to convert the circular motion of the steering wheel into the linear motion required to turn the wheels.
Helical gearing gives smoother and quieter operation for the driver.
The use of a variable rack still using a normal.
The rack and pinion steering box has a pinion connected to the steering column.
