Steering System

A steering wheel is a type of steering control in vehicles. The steering wheel is the part of the steering system that is manipulated by the driver; the rest of the steering system responds to the driver inputs. This can be through direct mechanical contact without or with the assistance of the Hydraulic Power Steering (HPS), or with the assistance of computer controlled motors, known as the Electric Power Steering (EPS).

The steering wheel is located directly in front of the driver’s seat. Turning the steering wheel transmits force, which turns the wheels to determine the direction of travel.

Most vehicles today have power steering, which makes turning the wheel relatively easy. The hydraulic power steering (HPS) is a hydraulic system for reducing the steering effort on vehicles by using hydraulic pressure to assist in turning the wheels. It is intended to provide for easier driving direction control of the car while preserving "feedback", stability and unambiguity of the trajectory specified.

The hydraulic power steering uses high pressure fluids for assisting the steering movement. When the driver turns the steering wheel, it opens up the flow or pressurized fluid in such a way that helps to turns the wheels in the required direction.

The electric power steering works with the help of an electric motor and an electronic control unit (ECU) which has some sensors.

The motor runs on battery and will use electric power to assist the movement of steering when the driver turns the wheel.

VII. Read the text “Exhaust System” and say why the exhaust system is very important for a good performance of a car.
