Description

Inflation-free hollow tire with Lelo triangular structure

Technical Field

The utility model relates to an exempt from to aerify tire technical field, the more specifically exempt from to aerify hollow tyre with lai luo triangle-shaped structure that says so.

Background

The non-pneumatic tire has been widely noticed, popularized and applied because of the advantages of no need of inflation, convenient maintenance, long service life, puncture resistance, wear resistance and the like, and the non-pneumatic tire comprises a non-pneumatic solid tire and a non-pneumatic hollow tire, the traditional molding process is mature for the production of the non-pneumatic solid tire, but the non-pneumatic hollow tire is difficult to finish by the traditional molding process. Meanwhile, the comfort problem of the non-pneumatic tire during riding is not fundamentally solved, and the production process is relatively complex. The traditional inflation-free tire represents an inflation-free hollow tire produced by Jiangxi tires, and the inflation-free hollow tire proposed by the company improves the comfort of the solid tire by arranging a hollow porous structure on the basis of the traditional solid tire, and adopts a screw extruder and a porous die head to extrude a tubular tire blank to obtain the inflation-free hollow tire by a butt joint molding process and the traditional mould pressing vulcanization molding; the bicycle has the advantages of no need of inflation, convenient maintenance, long service life, puncture resistance, wear resistance and the like, and has the disadvantages that the comfort problem in riding is not fundamentally solved, the tire body can only be designed in a miniaturized manner, and the production process is relatively complex.
