AI Technical Summary
Conventional airless tires made from polymeric materials are incompatible with extreme temperature variations and result in high contact pressures, sinking into soft ground and high rolling resistance, while existing manufacturing methods suffer from poor adhesion and complex geometries, leading to suboptimal performance and high costs.
An airless tire design with a corrugated tread and a single-piece construction using high-performance thermoplastic materials, combined with additive manufacturing, ensuring elasticity, improved grip, and reduced contact pressure, and a manufacturing process that simplifies assembly and reduces costs.
The design achieves enhanced traction, reduced ground damage, and improved manufacturing quality with lower costs, while maintaining structural integrity and endurance across extreme temperature gradients.
