Tyre makers Bridgestone have unveiled a new tyre they have created that requires no air inside to make it functional. The new airless tyres are instead equipped with resin spokes inside the tyre that provide support for the load of the vehicle.
The new resin spoke technology does not run from the inner circumference (rim) of the tyre to the outer circumference (tread) in a radial pattern. Instead, as pictured below, the angle of each spoke on the inner circumference of the tyre is about 45° different from that on the outer circumference, to provide extra support.
Innovative Design and Benefits
Also, because the new tyre design uses both dextral and sinistral spokes, the forces that deform the tyre tread do not become a turning force. This innovative design ensures that the tyre maintains its shape and functionality even under stress. The airless tyre also enables drivers to continue even if the outer skin of the tyre is punctured. This is a significant advantage over traditional pneumatic tyres, which can become unusable after a puncture.
The new tyre is also created from recycled rubber and plastics, and can be recycled again after use. This makes the tyre not only a technological marvel but also an environmentally friendly option. By using recycled materials, Bridgestone is contributing to reducing waste and promoting sustainability in the automotive industry.
Applications and Future Prospects
The potential applications for these airless tyres are vast. They could be particularly beneficial for off-road vehicles, military applications, and heavy machinery, where the risk of punctures is high and reliability is crucial. Additionally, the reduced maintenance requirements and longer lifespan of airless tyres could make them an attractive option for commercial fleets and public transportation systems.
Moreover, the airless tyre technology could pave the way for further innovations in the automotive industry. For instance, the integration of smart sensors within the tyre structure could provide real-time data on tyre performance, wear, and road conditions, enhancing safety and efficiency.
The new Bridgestone airless tyre technology is going to be showcased at the 2011 Tokyo Motor Show, which runs from December 3-11. This event will provide an excellent platform for Bridgestone to demonstrate the capabilities and advantages of their new airless tyres to a global audience.
In conclusion, Bridgestone’s airless tyre represents a significant advancement in tyre technology. With its innovative design, environmental benefits, and potential applications, it is poised to revolutionize the way we think about tyres and their role in transportation. As the automotive industry continues to evolve, innovations like these will be crucial in driving progress and sustainability.
