AI Technical Summary
In the existing technology, ordinary rubber tires and polyurethane tires have insufficient grip on low-temperature ice surfaces and are prone to slipping. Existing methods have limited effectiveness on thin ice surfaces and cannot completely solve the slipping problem.
A non-slip polyurethane tire is designed by filling silica gel particles into adsorption pores evenly distributed on the tire surface and connecting them to the outside through exhaust channels. The air in the adsorption pores is quickly squeezed out by the vehicle's compression action, keeping the tire adhering to the ground. At the same time, it absorbs ground moisture to increase friction. Combined with longitudinal and diagonal anti-slip patterns, the contact area is reduced, enhancing grip.
It significantly improves tire grip on cold, icy surfaces, prevents slippage, protects the integrity of the warehouse floor, extends tire life, and enhances handling stability and braking efficiency.
