Steering
Facts about steering systems
Rack-and-pinion is the most common steering system in late-model cars. It can be part of a hydraulic or electric power steering system. The steering rack, which is controlled by the steering wheel, directs the rod-operated linkages, which turn the wheels.
In a hydraulic power steering system, a high-pressure pump provides the required pressure.
Hybrid and electric vehicles use electric power steering systems, which are gaining in popularity because they reduce fuel consumption. Electric power steering can increase driving autonomy with new options, such as parking assistance.
Most vehicles today have a hydraulic steering pump that helps you steer. The pump is usually driven by the serpentine belt, but some newer vehicles have an electric pump.
