Power Steering System Components

Steering column or shaft.

Power steering system components. When the driver is not exerting force such as when driving in a straight line the system shouldn t provide any assist. There are several components in your vehicle s power steering system that make it easier to turn and steer the vehicle accurately. Typically the power steering system has been hydraulic but electric power steering systems are becoming increasingly more common. The following are the main components of steering system.

It serves the same function as a spool valve in a hydraulic power steering system. The steering torque sensor measures the steering force applied by the driver and enables sensitive control of the electric steering support. A power steering system should assist the driver only when he is exerting force on the steering wheel such as when starting a turn. In a modern power steering system the pump provides power steering fluid under pressure to the rack and pinion unit.

Each one of these components must stay functional for the steering to stay easy and simple. The system does not drag on the engine from. The configuration of an eps system can allow the entire power assist system to be packaged on the rack and pinion steering gear or in the steering column. Electric power steering systems consist of additional components including various sensors wires actuators motors and an electronic control unit.

Right tie rod arm spindle and kingpin 13. Left tie rod arm 11. Below is a list of the components of a car hydraulic power steering system. Track rod or tie rod 12.

The device that senses the force on the steering wheel is called the rotary valve. Electronic power steering systems eliminate the need for a pump hoses and a drive belt connected to the engine using variable amounts of power. Cars of old had huge steering wheels and required a lot of muscle to manage the manual steering system. The electric power steering system is typically part of the hi speed can bus on the vehicle.

The steering box system has many moving parts so is less precise than the rack system there being more room for wear and displacement. Hydraulic power steering system components. When the driver provides steering input by turning the steering wheel the power steering control valve applies fluid pressure to one side of a piston which assists the driver in turning the wheel. Thanks to technology modern vehicles are much easier to turn and steer.
