Study of Tweel Non-Pneumatic Tires

Abstract

Abstract: Non-Pneumatic Tyre (NPT) is an airless tire that supports the weight of the car. Although tires manufactured of solid rubber exist, they don't provide a smooth ride even though they have enough compliance if used in conventional vehicles. The NPT discussed here is mainly divided into three parts. Deformable spokes that support the downward weight, a rigid hub, Tread made out of rubber which comes into contact with the road and Reinforced shear band also plays a vital role. The properties of Non-Pneumatic Tyres like contact pressure, rolling resistance, and weight carrying capacity can be varied by differentiating the dimensions or the manufacturing materials used to produce NPT. Many kinds of research are taking place all over the world to make NPT an alternative option to the traditional pneumatic tire over a decade. This paper integrates an overview of the research works that were carried out to develop and improve NPT. Keywords: Pneumatic, Tweel, Honeycomb structure, Hyperelastic
