3. Introduction
 Steering is the term applied to the collection of
components, linkages, etc. Which will allow a vehicle to
follow the desired course.
 An automobile is steered with the help of steering gears
and linkages which transfer the motion of the hand
operated steering wheel to the pivoted front wheel hubs
via steering column. The other parts that are used for
steering a vehicle are steering wheel pads, steering shaft,
steering box, steering arm and steering stabilizers. These
parts are made of durable materials like stainless steel,
iron, aluminium, copper, magnesium, etc.

4. FUNCTION OF A STREEING SYSTEM
To Control The Angular Motion of Wheel And Thus
The Direction Of Motion Of The Vehicles.
To Provide Directional Stability Of The Vehicle While
Going Straight Ahead.
To Minimize Tyre Wear And Increase Its Life.

5. TYPE OF STEERING
 STEERING
 MANUAL
 RACK AND PINON
 WORM AND ROLLE
 POWER
 HYDRALIC
 ELECTRIC

6. Components of Steering System
 STEERING WHEEL : A wheel turned by the driver of a
motor vehicle, ship, etc, when he or she wants to
change the direction of the vehicle or ship.
 STEERING COLUMN : A shaft connecting the steering
wheel to the steering gear assembly. It is also called
steering shaft

7. BASIC RACK AND PINION STEERING
PINION GEAR : Rotated by the steering wheel and
steering shaft, it’s teeth mesh with the teeth on the
rack.
RACK : Long steel bar with the teeth along one
section, slides sideways as the pinion gear turns

8. STEERING LINKAGE
PITMAN ARM :
Transfers gearbox motion to the steering linkage. Pitman arm
is splinted to the gearbox

9. BASIC RACK AND PINION STEERING
GEAR HOUSING :
It Holds the pinion gear and rack.
 TIE RODS :
Connects the rack with the steering Knuckle

10. NEED POWER STEERING
 Power steering greatly reduces the effort needed
to turn the wheels of a car especially with front
drive cars, the extra weight and effort can be too
much for many drivers. Although not a major
concern at highways speeds, low speed turning
and manoeuvring are much easier to do. Most
power steering systems provide less and less boost
the faster you go

11. POWER STERING
An automobile steering system in which the
engine’s power is used to supplement the driver’s
effort in turning the steering wheel.
The first power steering system on an automobile
was apparently installed in 1876 by a man with the
surname of FITTS. Next power steering system
was put on a Columbia 5-ton truck in 1903
 There are two types of power steering
 1 Electric power steering
2 Hydraulic power steering

12. HYDRAULIC POWER STEERING
 Most power steering systems
work by using a hydraulic system
to steer the vehicle’s wheels. The
hydraulic pressure typically
comes from a rotary vane pump
driven by the vehicle’s engine. A
double acting hydraulic cylinder
applies a force to steering gear
which in turn steer the road
wheel. The steering wheel
operates valve to control flow to
the cylinder.

13. ELECTRIICAL POWER STEERING
 Electric power steering uses the
electric motor to assist the driver of
a vehicle. Sensors detect the
position and torque of the steering
column and computer module
applies assistive torque via the
motor, which connects to either the
steering gear or steering column.
