there are three different types of power steering systems available today; rack and pinion, recirculating-ball, and the steer-by-wire. the rack and pinion power steering system is on most modern passenger vehicles today. how it works is when you turn you're steering wheel there's teeth on the rack and teeth on the pinion that fit in with each other. as you turn the steering wheel, the pinion turns which turns the rack, and the rack is indirectly connected to the wheels. you may be asking where the power comes from then, well there's two possibilities; hydraulic and electric.
in hydraulic power steering there is what's called a power steering pump which connects to the engine by a belt which in turn is wrapped around a pulley. power steering fluid is pushed into a piston which is located at the center of the rack. the amount of power steering fluid dispersed is determined by the speed of the engine. when the power steering fluid enters the hydraulic piston it tells the wheels which way to turn depending on which way the steering wheels is turning because its allows the fluid to move through it.
electric power steering systems are just like they sound. they use either one or more electric motors to operate the steering system, they're called the ecu or electronic control unit. if the ecu fails, you still have steering, but it won't be powered.
