Power Steering System

Power assisted steering overcomes the problem.

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. The oil works a piston that helps to push the steering in the appropriate direction. These modules share information for vehicle speed steering angle and engine operation. When the driver is not exerting force such as when driving in a straight line the system shouldn t provide any assist.

A power steering system should assist the driver only when he is exerting force on the steering wheel such as when starting a turn. The device that senses the force on the steering wheel is called the rotary valve. On this network is the ecm for the engine and abs stability control system. 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.

Valves in the steering rack or box open whenever the driver turns the wheel allowing oil into the cylinder.
