The invention relates to a tire body structure, in particular to a truck radial tire body structure. The tire body structure of the truck radial tire comprises a tire crown part, a base part positioned on the lower layer of the tire crown part and tire sidewalls below two tire shoulder parts, a lining layer is arranged on the inner side of the tire; a layer of tire body is arranged on the outer side of the lining layer; two sides of the tire body bypass the steel wire ring to be turned outwards and wrapped at a triangular part to form a tire bead part, the tire body is formed by calendering and combining a three-phase alloy steel wire cord and cobalt-free tire body rubber, and a plating layer of the steel wire cord contains 64.5%-69.5% of Cu, 26.5%-31.5% of Zn and 3%-5% of Co. According tothe tire body structure, the three-phase alloy steel wire cord threads (TAWI) and the cobalt-free tire body rubber are combined in a calendering mode, the tread structure can improve the adhesive force of rubber materials and steel wires under damp and hot aging, heat generation of a tire body is reduced, and the service life of a tire is prolonged.

    本发明涉及一种胎体结构,具体涉及一种载重子午线轮胎胎体结构。本发明载重子午线轮胎胎体结构包括胎冠部、位于胎冠下层的基部及两胎肩部下方的胎侧,在轮胎的里侧设有内衬层,内衬层的外侧设有一层胎体,胎体的两边绕过钢丝圈向外翻卷包置于三角部位形成胎圈部,所述胎体由三相合金钢丝帘线和无钴的胎体胶压延组合而成,钢丝帘线的镀层中含有64.5%~69.5%的Cu,26.5%~31.5%的Zn和3%~5%的Co。本发明的胎体结构使用三相合金钢丝帘线(TAWI)和无钴的胎体胶进行压延组合,这种胎面结构可以提升胶料与钢丝在湿热老化下的粘合力,降低胎体的生热,提升轮胎使用寿命。
