Simple rack and pinion steering diagram.
Rack and pinion steering is quickly becoming the most common type of steering on cars small trucks and suvs.
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.
Helical gearing gives smoother and quieter operation for the driver.
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 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.
Both the pinion and the rack teeth are helical gears.
