Bending plate type tire and manufacturing method thereof

Abstract

The invention discloses a bending plate type tire device. The bending plate type tire device comprises a wheel rim, wherein a plurality sets of supporting pieces which are continuously bended are fixed on the circumference annular surface of the wheel rim through fastening pieces; a band lining is arranged on the outer parts of the supporting pieces in a padding manner, and is wrapped with a packing piece, or an inflatable cover tire is arranged on the outer part of each of the supporting pieces; the longitudinal section of each supporting piece is in a flat S shape, and each supporting piece is divided into a mounting section, a neck bend, a straight section, a shoulder bend, a working section and a tail section, wherein a tail inserting groove is formed in the surface of the tail end of the working section, and is circular; a jointed part of the tail inserting groove and the tail section of each supporting piece forms a triangular space; a plurality of bosses radially facing outwards are arranged at the position, close to the tail section, of the tail inserting groove. According to the bending plate type tire disclosed by the invention, compared with the prior art, one or more sets of plate-shaped elastic supporting pieces which are mutually connected and continuously bended are mounted on the wheel rim, so that the functions of elastically supporting a wheel load, driving and braking are realized, and the requirement that a vehicle can durably and safely operate in multiple complex and harsh environment is met.

Description

technical field [0001] The invention belongs to the technical field of non-pneumatic tire manufacturing, and in particular relates to a bent plate tire and a manufacturing method thereof. Background technique [0002] Pneumatic tires commonly used at present, after more than a hundred years of development, the technology has been quite mature, the structure is relatively simple, and the elasticity from the whole to the part is very good, but the manufacturing process is complicated, especially after the development of radial tubeless tires. In terms of meeting the increasingly stringent requirements of vehicles on tires such as high speed, heavy load, durability, comfort and safety, the corresponding technical improvement of pneumatic tires has stagnated for a long time. In particular, the chronic problems of inflation leakage and tire blowout have always made users feel inconvenient and worry about driving accidents. Therefore, many people have found another way to focus on...

AI Technical Summary

Problems solved by technology

The practicability of the above-mentioned tires is not ideal, and its tire support system is mostly constructed by elastic supports without effective preload; in the first four tires, the webs, spring sheets and spokes as support members work independently. When the tire is running, the support members lack the smooth transmission of support force among each other; there are many stress concentration parts in the first two tires, which will cause the elastic support function of single-piece web, spoke, spring leaf, etc. The excessively high requirements will make the wheels run unevenly; the number of elastic supports in the third and fifth types of tires is too large, and once foreign matter such as sand enters the carcass, it will not be easy to discharge, thus affecting the normal performance of the tire. to play
