Automobile engineering is a growing aspect in todays world because of the steady growth of the automobile industry.This sample paper covers the course and is really very good for the automobile engineering students.
The Power Steering Rack is a link between the steering wheel and the inner
tie rods. The power steering rack makes it easy
for you to steer your vehicle in the right direction.
The rack and the pinion is confined in a metal tube. The ends of the
rack protrude from the sides of the tube and are connected to a rod called the tie rod.
In a power steering system, the rack has a cylinder with a piston.
There are two fluid channels, one on either side of the piston.
The piston is forced to move by supplying high pressure fluid from one side of the piston.
This results in the movement of the rack. The power steering rack
converts the steering wheel’s rotational motion into linear motion and provides gear reduction. If your car’s power steering rack is not
functioning properly, you must look into the issue as quickly as possible.
At Buy Auto Parts you will find high-quality power steering racks at the best prices, and
