Introduction
Steering is the term applied to the collection of components, linkages, etc. which allow for a car or other vehicle to follow a course determined by its driver. Vehicle performance depends highly on good steering control, which provides an accurate feedback about how the vehicle reacts to the road.
What is Power steering?
Power steering is a system for reducing the steering effort on cars by using an external power source to assist in turning the wheels.
Most new vehicles now have power steering.
Advantages of using Power Steering
Requires minimal physical exertion.
Very fast to turn lock to lock without much force.
Can be set up permitting vehicle to travel in a straight line without driver input on a constant camber road in still conditions.
Blowouts etc. cannot affect steering wheel or the direction of the steered wheel which can only be moved by steering wheel input.
Electronic power steering
Electric power assisted steering (EPS) uses an electric motor to provide directional control to the driver. Most EPS systems have variable assist, which provides more assistance as the speed of a vehicle decreases and less assistance from the system during high-speed situations. This functionality requires a delicate balance of power and control that has only been available in recent years. The EPS system is replacing the hydraulic steering system and is destined to soon become mainstream among automotive manufacturers.
