Power Steering System

The device that senses the force on the steering wheel is called the rotary valve.

Power steering system.

The electric power steering system is typically part of the hi speed can bus on the vehicle. Valves in the steering rack or box open whenever the driver turns the wheel allowing oil into the cylinder. These modules share information for vehicle speed steering angle and engine operation. 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.

When the driver is not exerting force such as when driving in a straight line the system shouldn t provide any assist. The oil works a piston that helps to push the steering in the appropriate direction. The engine drives a pump that supplies oil under high pressure to the rack or the steering box. A power steering system should assist the driver only when he is exerting force on the steering wheel such as when starting a turn.

Power assisted steering overcomes the problem.
