Principles of Steering

1 What isthe purpose of the steering ?
provides control over direction of travel, good manoeuvring, smooth recovery from turns and minimum transmission of road shocks.
2 How is four wheel steering controlled ?
can be controlled electronically or mechanically.
3 What is the purpose of power steering ?
to help the driver turn the wheel with less effort.
4 How do you describe steering geometry ?
the relationships between the steering system, the wheel positions and the suspension system form what is called the steering geometry.
5 What 2 different types of steering are there ?
Rack and pinion and worm gear
6 What connects to the steering rack to the wheels ?
tie-rods
7 Why is a rack and pinion used ?
because the construction is compact and light weight
8 What are the purpose of of the bearings in the steering box ?
to reduce friction and wear and to reduce end  float
9 What is the purpose of a worm gear steering box ?
for better control steering
10 How does the power steering work ?
the power steering pump, pumps the steering fluid to the steering gear box, which flows to the valve body unit. once you turn the wheel to the left or to the right , the computer tells the steering fluid to push against the crank to make the wheels move, taking less stress off the driver.
11 What is the purpose of the steering column ?
to transfer the drivers input torque from the steering wheel.

12 What has been added to some modern steering columns to reduce the risk of injury in a front end collision. Explain what happens to the steering column in a front end collision ?
