Component Parts of Manual Steering
System

5. ATS NC IITraining Session
Objectives:
 Identify the component parts of a manual
steering system

6. LESSON:
Component Parts of Manual Steering
System

7. INTRODUCTION
The steering system converts the
rotation of the steering wheel into a
swiveling movement of the road wheels in
such a way that the steering-wheel rim turns
a long way to move the road wheels a short
way. The system allows a driver to use only
light forces to steer a heavy car.

8. Component Parts
of
Manual Steering
System

9. 1. STEERINGWHEEL
It used by the driver to rotate the steering
shaft that passes through the steering column.

13. 2. STEERING COLUMN
It is a housing and support the steering
shaft by its rotation.

17. Component Parts
of
Steering Column

18. A. STEERING SHAFTS
It connects to the steering gearbox
through one or more universal joints or
flexible steering coupler. It transfer the
rotating motion from the steering wheel to
the steering gearbox

21. B. UNIVERSAL JOINTS/FLEXIBLE
STEERING COUPLER
It provide the attachment between the
steering shaft and the splined in input shaft of
the steering gearbox.

25. 3. STEERING GEARBOX
It changes the rotary motion of the
steering wheel into linear motion of the
steering linkage

26. RACK AND PINION GEARBOX

27. RECIRCULATING BALL GEARBOX

28. Kinds
of
Steering Gearbox

29. TwoTypes of Steering System
1. Rack and Pinion Steering Gearbox
2. Recirculating Ball Steering Gearbox

30. 1.RACK AND PINION STEERING
GEARBOX
It converts the rotational motion of the
steering wheel into the linear motion needed
to turn the wheels. And also it is common used
by the light-duty vehicles.

33. Parts of Rack and
Pinion Steering Gearbox

34. A. PINION
It is connected to the steering column.
As the driver turns the wheel, the forces are
transferred to the pinion and it then causes
the rack to move in either direction. This is
achieved by having the pinion in constant
mesh with the rack.

39. 2. RACK
It slides in the housing and is moved by
the action of the meshed pinion into the teeth
of the rack. It normally has an adjustable bush
opposite the pinion to control their meshing,
and a nylon bush at the other end.

44. 2.RECIRCULATING BALL STEERING
GEARBOX
It is used on many trucks and SUVs
today. The linkage that turns the wheels is
slightly different than on a rack-and-pinion
system. The recirculating-ball steering gear
contains a worm gear.

50. Parts
of
Recirculating Ball
Steering Gearbox

51. A. WORM GEAR
It is a round-shaped threads that steel
balls fit in and holds the ball nut.

55. B. BALL NUT
It is a housing of recirculating ball
bearing and it drives the sector gear back
and forth.

60. C. SECTOR GEAR
It rotates around its axis as its teeth move
along the worm gear and moves the Pitman
arm.

65. D. Recirculating ball bearing
It act as a bearing to reduce the friction
between the worm and ball nut. Ball guides
on one side of the ball nut allow the balls to
recirculate as the worm turns to screw the
nut back and forth on the worm.

69. E. PITMAN ARM
It transfer steering box motion to the steering
linkage. The pitman arm is splined to the steering
box sector (output) shaft. A large nut and lock
washer secure the arm to its shaft.

74. 4. STEERING LINKAGES
It connects the linear motion of the
steering gear to the steering arms.

76. Parts
of
Steering Linkages

77. A. CENTER LINK
It is the steel bar that holds all other
steering and connecting arms such as the idler
arm, tie rod ends, and the rack end.

81. B. IDLER ARM
It supports the end of the centre link on
the passenger side of the car. The idler bolts to
the car frame or subframe.

86. C. RUBBER BELLOW
It is attached to the both end of rack and
pinion housing. It protects the inner joints of
rack end from dirt and contaminants. In
addition, it retains the grease lubricant inside
the rack and pinion housing.

91. D. RACK END
It also known as Axial Joints, are used in
rack-and-pinion steering systems. Providing a
connection to the outer tie rod ends, a Rack
End connects the steering rack to the tie rod,
which connects to the wheel.

94. E. TIE-ROD END
It is attached to the tie-rod shaft. These
pivot as the rack is extended or retracted
when the vehicle is negotiating turns. Some
tie-rods and tie-rod ends are left or right hand
threaded. This allows toe-in or toe-out to be
adjusted to the manufacturer's specifications.

105. F. STEERING ARM
It is the part of a vehicle's chassis that
directs the input from the steering box to its
components. It applies pressure from the
steering box to the tie rods and results in the
tires turning from left to right, or right to left.

109. G. STEERING KNUCKLE
It is a part of the suspension system which
links the wheel assembly and the steering
components.

112. H. BALL JOINT
It consist of a ball and socket similar to
the hip joint of the human body. Ball joints of
your front suspension provide pivoting
movement between the steering knuckles
and control arms to provide a safe, smooth
ride and allow you to precisely control your
vehicle.
