Power Assisted Rack And Pinion Steering System

There are advantages to both but there are some.

Power assisted rack and pinion steering system. There is fluid on both sides of the piston. A rack and pinion gearset is enclosed in a metal tube with each end of the rack protruding from the tube. Power steering in a recirculating ball system works similarly to a rack and pinion system. It is actually a pretty simple mechanism.

Power assisted steering on a heavy car either the steering is heavy or it is inconveniently low geared the steering wheel requiring many turns from lock to lock. This allows for a better steering feel at speed and reduces the possibility of over steering in a evasive or abrupt maneuver. Rack and pinion is almost always power assisted. Assist is provided by supplying higher pressure fluid to one side of the block.

As epas electric power assisted steering systems have been developed and refined however manufacturers like porsche have managed to create electronic systems that all but match the feel of a. Working of basic power steering system. Rack and pinion steering is quickly becoming the most common type of steering on cars small trucks and suvs. A rod called a tie rod connects to each end of the rack.

Now let s take a look at the other components that make up a power steering system. Variable assist power steering is a nice system that regulates hydraulic pressure to provide greater assist at idle or slow speeds and reduce the assist at higher speeds. Rack and pinion systems are a common component in railways. A typical power steering system utilizes the same mechanism as the normal steering with the addition of a hydraulic system that generates the power needed to assist in the steering effort.

When pressure is placed on the fluid on one side of the piston it forces the piston to move which turns the rack and assists with steering. When comparing steering systems you really only need to think about two types standard mechanical steering and rack and pinion steering. A cylinder with a piston in the middle is placed in the rack. The standard mechanical steering system is either power assisted or non power.

With rack and pinion steering the rotation of the pinion causes linear motion of the rack which turns the vehicle s wheels left or right. The following describes how a basic power rack and pinion steering system works. When a rack and pinion system is connected to a power steering system the design changes slightly. For use on all power assisted sterndrive boats with steering wheels up to 16 diameter.
