3.  The wheel hub is one of the crucial part of
wheel that include spokes at the center of most
wheels.
 A hub assembly contains the wheel bearing ,
and the hub to mount the wheel to vehicle.
 It is located between the brake rotors and axle.

5.  By GERHARD FISCHER ,SAE
INTERNATIONAL
 Design of wheel should be based on stress
generated under consumer usage.
 It is highly steered safety components which
must not fail under loading condition.
 Main parameters for design is loading
condition , manufacturing process and material
behavior.

6.  BY : AUTHOR S DHAR ,VOL 9,
 Catastrophic failure of wheel hub occurred
during service.
 Nature of crack was corner crack.
 The initiation of crack is complex.

7. After studying the literature ,the failure of wheel
hub are due to the following reason:
1) lack of lubrication
2) overloading the vehicle
3) installing the nut either too tight or too loose
This all problem occur at the time of loading
condition.

9.  The bolt pattern is determined by the number
of bolts on the wheel hub.
 Selection of material strong enough to hold the
weight of car
 Type of lug nuts or bolts
 Standard dimensions of wheel hub used in
cars.

17.  After doing study on wheel hubs, we found
that the below mentioned materials are being
generally used for making of wheel hubs:
1. Aluminum (1060 alloy)
2. Steel (AISI 1035 steel)
3. Titanium
4. Composites (fiber and glass reinforced)

18.  Aluminum:
1. Advantages: Light in weight, Corrosion
Resistant, Recyclable after usage
2. Disadvantages: Cost, Machining
 Steel:
1. Advantages: Cost effective, Availability, Mostly
used, Moderate properties
2. Disadvantages: Weight

19.  Titanium:
1. Advantages: Corrosion Resistant, High
Strength, Light Weight
2. Disadvantages: Machining and
Manufacturability, Cost and Availability
 Composites:
1. Advantages: Mixed Properties, Light Weight
2. Disadvantages: Not Reliable, Developing
Technology

20.  After studying their properties we found that
aluminum 1060 alloy and AISI 1035 steel are best
suitable out of four materials for making wheel
hub. Their properties are as follows:
AISI 1035 Steel:

21.  Aluminum 1060 Alloy:

28.  With Minimum F.O.S = 5.4

34.  With minimum FOS =3.8

36.  Wheel hub has been designed in SOLID WORKS
software with the given parameters. The designed
assembly gives the stability during the rotation of
wheel
 Based on analysis of stress distribution ,strain ,
fatigue analysis we found that aluminum 1060
alloy is better material for the wheel hub than
AISI 1035 steel.
 The factor of safety for aluminum 1060 alloy and
AISI 1035 steel are 5.4 and 3.8 respectively. It
signifies that aluminum 1060 alloy is more reliable
than AISI 1035 steel
