Embodiment Construction

[0028] By changing the belt width, the effect of different belt widths on tire shoulder durability is studied, and five different belt widths are mainly compared. The specific scheme is shown in Table 1 (the unit is mm).

[0029] Table 1 Different Belt Width Parameters

[0030]

[0031] Using finite element analysis software and tire-specific finite element analysis preprocessing software TYABAS 3.0, the above five different belt width design schemes were modeled and simulated, and the belt tension amplitude and angle transformation were mainly analyzed. The results of finite element analysis are shown in Table 2.

Abstract

The invention discloses a tire belt ply structure, in particular to an all-steel meridian (TBR) tire, and aims to improve the durability of the tire by designing the width and angle of a belt ply.

Description

technical field [0001] The invention belongs to the field of tire belt structure design, in particular to a belt-optimized all-steel radial (TBR) tire structure. Background technique [0002] Tires are typical elastic structures composed of rubber and skeleton materials. The fatigue damage of tires is the main form of tire damage. According to the damage location, it can be divided into the bottom of the groove, the belt layer and the end, and the mouth. Part cords and reinforcing material between layers and ends. Around tire fatigue damage, tire structural engineers and many scholars have done a lot of research work. The existing technology includes increasing the hardness and thickness of the bead apex, while appropriately increasing the height of the apex (but the height of the turn-up should not be increased), and adding steel wire cloth to the sidewall to greatly increase the rigidity of the sidewall, thereby improving the bezel. durability etc. [0003] The belt lay...
