Tire bead structure having high density exhaust line

Abstract

The invention relates to a tire bead structure having high density exhaust line. The tire bead structure comprises a lining layer, a steel wire seam allowance, a tire body, a triangular body, a steelwire ring, a wear-resistant colloid and an exhaust line, which are sequentially distributed from inside to outside; the exhaust line is of a high-density latticed structure and comprises radial linesand circumferential lines, the radial lines are arranged in the circumferential direction in a 32-equal-division mode, the multiple circumferential lines are concentrically arranged at intervals, andthe radial lines and the circumferential lines are arranged in a crossed mode. By means of the latticed structure, the heat dissipation factor is fully considered, wherein the four-direction exhaust is more beneficial to uniform transition of rubber materials during tire vulcanization, so that the material of the tire bead part is fuller, the strength of the tire bead is higher, and the bearing capacity is better.

Description

technical field [0001] The invention belongs to the technical field of tire structures, and in particular relates to a bead structure with high-density exhaust lines. Background technique [0002] The domestic transportation industry is developing faster and faster, which brings more and more tire wear and tear. Tires have two hard contact points, namely, the contact between the tread and the ground, and the contact between the bead and the rim. With the complexity of tire use, Such as long-distance driving, the use of overloading will lead to an increase in tire deformation, and the increase in tire deformation will lead to excessive heat generation, which in turn will cause the phenomenon of tire shoulder empty, slit empty and so on. [0003] The bead part structure of normal tires will be provided with an exhaust line at the contact between the bead and the rim, which mainly plays the role of exhausting the tire during vulcanization, so that the rubber material transition...

AI Technical Summary

Problems solved by technology

In fact, this is a difficult problem faced by tire companies. The common practice of tire companies is to reduce the diameter of the bead and increase the amount of interference fit. The disadvantages are also obvious, and the displacement is less, but the circumferential position is moved downward instead, and there is no heat generation. Reduce; it will easily cause wire snagging, broken wire explosion, etc.
