Traditional pneumatic tires have several drawbacks: they require air pressure maintenance, are prone to punctures, create rolling energy losses, and are difficult to recycle. Additionally, for vehicles like bicycles, where efficiency is crucial, energy loss from tire deformation can be a major limitation. Existing non-pneumatic tires, while puncture-proof, suffer from issues like material fatigue, excessive vibration, and uneven stress distribution.
The Invention
This new suspension tire eliminates the need for air by using corrugated rings made of resilient, elastic material. The tire consists of:
- A tread ring that contacts the ground.
- A mounting ring that connects to the wheel.
- Multiple corrugated rings between these two layers, which have alternating convex and concave curvatures to absorb impact and distribute force efficiently.
Instead of relying on air pressure, this design naturally bends and bulges upon contact with the ground, providing built-in suspension and reducing stress on the wheel.
The Key Innovation
Unlike traditional non-pneumatic tires that mainly absorb force in the vertical direction, this tire redirects the load forces tangentially, reducing resistance and enhancing suspension. The misaligned spacer mounts connecting the rings prevent stress concentration, ensuring a smoother ride.
Benefits
- Puncture-proof: Eliminates the risk of flats.
- Energy-efficient: Reduces rolling energy losses, improving efficiency for bicycles and electric vehicles.
- Better ride quality: The natural deformation of the tread ring provides superior suspension and reduces vibrations.
- Sustainable & easy to install: Made from recyclable materials, with an easy mounting system.
Impact
This tire could revolutionize industries by enhancing the durability and efficiency of vehicles, reducing waste from discarded rubber tires, and making transportation more sustainable. Whether for bicycles, cars, or other wheeled vehicles, it offers a smarter, greener alternative to traditional tires.
