Power Steering System

And the power steering system is the advanced steering system in which the effort required to steer the front wheels of the vehicle side to side is reduced by using intermediate electric or hydraulic devices that multiplies the force applied by the driver through steering wheel in order to achieve smooth and quick directional change of the vehicle.

Power steering system.

On this network is the ecm for the engine and abs stability control system. The device that senses the force on the steering wheel is called the rotary valve. When the driver is not exerting force such as when driving in a straight line the system shouldn t provide any assist. The engine drives a pump that supplies oil under high pressure to the rack or the steering box.

These modules share information for vehicle speed steering angle and engine operation. Power assisted steering overcomes the problem. Valves in the steering rack or box open whenever the driver turns the wheel allowing oil into the cylinder. A power steering system should assist the driver only when he is exerting force on the steering wheel such as when starting a turn.

Hydraulic or electric actuators add controlled energy to the steering mechanism so the driver can provide less effort to turn the steered wheels when driving at typical speeds and reduce considerably the physical effort necessary to turn the wheels when a vehicle is stopped or moving slowly.
