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. A typical rack and pinion steering layout showing how the rack acts directly on the road wheel steering arms. Helical gearing gives smoother and quieter operation for the driver.

Working principle of rack and pinion steering gear. 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. It is actually a pretty simple mechanism.

Both the pinion and the rack teeth are helical gears. A rack and pinion gearset is enclosed in a metal tube with each end of the rack protruding from the tube. It also provides a gear reduction so turning the wheels is easier. The steering system converts the rotation of the steering wheel into a swivelling movement of the road wheels in such a way that the steering wheel rim turns a long way to move the road wheels a short way.
