輪胎胎邊強化結構Tire bead reinforcement structure

本發明係涉及一種輪胎，特別是指一種輪胎之胎邊強化結構創新結構型態揭示者。The present invention relates to a tire, and more particularly to an innovative structural type revealer of a bead reinforcement structure of a tire.

傳統輪胎結構型態設計上，具有凹凸紋型態的部份係集中於輪胎的胎面區域，藉以達到止滑及排水等功效，而輪胎的兩側胎邊部位則通常為平滑之環面型態。In the traditional tire structure design, the part with the embossed pattern is concentrated on the tread area of the tire, so as to achieve the effect of slippage and drainage, and the sidewalls of the tire are usually smooth and toroidal. state.

雖然，後續亦有相關業界開發出一些於輪胎胎邊設置凹凸紋路的結構型態，但此等設計通常為圖案裝飾或廣告表現性質，對於輪胎的結構功能部份並無助益；而縱使有少數標榜具有胎邊保護功能之紋路型態者，亦因其型態設計考量不週，因此實際上往往仍舊無法對輪胎胎邊產生較為理想實用的結構強化效果，此部份實為值得相關業界再思索改進之重要技術課題。Although there are some related industries that have developed some embossed textures on the sidewalls of tires, these designs are usually patterned or advertised, which does not help the structural function of the tires. A few of the styling patterns with the bead protection function are also considered by the type design. Therefore, in fact, it is still impossible to produce an ideal and practical structural strengthening effect on the tire bead. This part is worthy of the relevant industry.
