All-steel tubeless radial tire with high load performance and manufacturing method thereof

Abstract

The invention discloses an all-steel tubeless radial tire with a high load performance and a manufacturing method thereof. A rectangular bead ring is arranged in a compound bead ring; a section designangle is adopted by a profile curve at the bottom of a bead base; a tangent design angle is adopted by the profile curve of a tire bead heel; a sizing material is thickened on a contact position of the bead heel and the rim; binding rubber slices are arranged at two endpoints of a tire cord fabric and a reinforced cord fabric; the height of reverse binding sections of the binding rubber slices isarranged close to the height H1 of a horizontal shaft; an upper filling glue and a lower filling glue for isolation are successively arranged between the reverse binding sections of the binding rubber slices and the tire body from top to bottom; a U-shaped reinforced cord fabric layer is paved on the outer layer of the tire cord fabric; an inside liner and a sidewall compound piece are respectively arranged on the inner and outer sides of the reinforced cord fabric. The bead ring is stable in construction, is free from deformation under a stressed state and is high in strength use ratio; thebottom of the bead ring is in surface contact with the rim; the stress is uniform and the load resistance is promoted; the stress between the tire body and the tire cord fabric is buffered by the isolating rubber slices; the loading capacity is promoted by the reinforced cord fabric.

Description

technical field [0001] The invention belongs to the technical field of all-steel tubeless radial tire production, and in particular relates to a high-load performance all-steel tubeless radial tire and a manufacturing method thereof. Background technique [0002] The tubeless ratio of radial tires is getting higher and higher. Most of the existing all-steel tubeless radial tires are only suitable for use under standard loads or light loads. Load-bearing performance all-steel radial tubeless tires. [0003] The tubeless tire bead is usually wound with a rubber-coated steel wire with a circular cross section; the contact part of the tire contour curve and the rim is designed with two different angles; the heel position is designed with an anti-arc. [0004] To improve the load performance, some are reinforced with U-shaped reinforced layer cords, some are reinforced with U-shaped reinforced layer cords with one or two layers of fiber-wrapped cloth, and some are reinforced wit...

AI Technical Summary

Problems solved by technology

[0011] Aiming at the technical problems of poor tire load performance in the prior art that lead to bead voids, ring cracks, and wire bursts, the purpose of the present invention is to provide a high-load performance all-steel tubeless radial tire and its manufacture The method is applied to tires with high load performance, that is, to enhance the ability of tires to carry loads and run normally, and adopt a new structure and manufacturing process
