AIRLESS TYRE/ NON-PNEUMATIC TYRE

Presented

by

Team No.1Slide2

TopicsWhat is a pneumatic tyre and its drawbacks.

What is an airless tyre?

How it works?

Different design approaches.

Advantages and disadvantages.

Applications.Slide3

Pneumatic tyres

pneumatic

, or 

air-filled

, tyre is made of an air tight inner core filled with pressurized air.The pressure of the air inside the tyre is greater than atmospheric air pressure, so the tyre remains inflated even with the weight of a vehicle resting on it.It gives a certain degree a cushioning effect as the tyre hits bumps in the road.Slide4

Drawbacks

Puncture or Blowout

.

A

 

blowout at high speeds can lead to a dangerous car accident.Variations in air pressure changes tyre performance.Can blow out by gunfire or explosion.Slide5

What is airless tyre?

Airless

tyres

or

Non-pneumatic tyres (NPT) , are tyres that are not supported by air pressure.Slide6

continued..Slide7

How it works?

The flexible tread and shear bands deform temporarily as the spokes bend, then quickly go back to the initial shape.Slide8

Advantages

Eliminates

air leaks or tyre blow

outs.

No

maintenance required.Facilitate recycling.Remains mobile even with some of the spokes are damaged or missing.Durability & Long Life.Can take gunfire or explosion.Less environmental impact.Slide12

Disadvantages

Lack of

adjustability.

Vibration.

Different

Manufacturing technique.Not as economic as pneumatic tyres.Slide13

Applications

U

sed

on some small vehicles such

as riding lawn

mowers andmotorized golf carts.In backhoe or bulldozers.Slide14

continued..

For Military vehicles

Also used in

All Terrine Vehicles (ATV)Slide15

Conclusion

For years, vehicles have been running on pneumatic

tyres

and there was almost a full stop for any further improvement of

tyres

. In 20th century the engineers have come up with a new concept where the tyres never require air, if the drawbacks that are being encountered presently are and improved then there is good future for these tyres. And the vehicles can run without the necessity of air.Slide16
