2. Steering system
❖ Steering:
➢ To control/steer something or to handle
something.
❖ System consist of…
❖ Basically,It is the key interface
between driver and vehicle.
❖ Its mechanism used to control the
path followed by vehicle.

3. Steering linkages
There are certain types of linkages shown below

4. Terms related to steering

5. Continue..
The caster angle is the game between vertical axis and steering axis!

6. Continue..
● Seen Position!
● Can be effect on in ______ at some terrain situations.

7. SAE forces and moment on tire

8. Steering
Geometry
It is the
geometric
arrangement
of the parts of
steering
system

9. Ackermann Geometry
The typical steering system is used in
road cars.
It has tie-rod linkages and steering arm
that form an approximate parallelogram,
If the steering arm are angled,this is
known as Ackermann geometry.
If the steering arms are parallel, then
both wheels are steered to the same
angle.

10. The perfect Ackermann is difficult to
achieve but
Another condition of ackermann
To have all wheels turning freely on a
curved road, all the tire axes must
intersect at a common point. This
criteria is the Ackerman condition.
Ackermann Geometry

11. Anti-Ackerman Geometry
The typical steering system is used in
race cars.
The key-difference between ackerman
and anti-akermann is the turning of the
_____ wheel.
THe effort of the driver in this anti
Ackerman geometry is____

12. Geometry effects on Steering condition
The Ackerman geometry sometimes
cause the ________ steering effect
while turning.
And the anti Ackerman geometry
sometimes cause the -----------steering
effect while turning.
