The invention relates to the technical field of tires, in particular to an all-steel radial truck tire which comprises a triangular rubber core, a tire body cord fabric layer, an outer seam allowance reinforcing cord fabric layer, an inner seam allowance reinforcing cord fabric layer and an outer fiber cord fabric layer. The tire body cord fabric layer wraps the apex rubber core, and the upper end of the tire body cord fabric layer is wrapped with a first protective layer; the outer seam allowance reinforcing cord fabric layer is arranged on the surface of one side, far away from the apex core, of the part, located on the outer side of the tire bead structure, of the tire body cord fabric layer, and the end of the upper end is coated with a second protective layer; the inner seam allowance reinforcing cord fabric layer is arranged on the surface of one side, far away from the triangular rubber core, of the part, located on the inner side of the tire bead structure, of the tire body cord fabric layer, and the upper end is coated with a third protective layer; the outer fiber cord fabric layer is arranged on the side, away from the tire body cord fabric layer, of the outer seam allowance reinforcing cord fabric layer, and the upper end of the outer fiber cord fabric layer is higher than the outer seam allowance reinforcing cord fabric layer. According to the all-steel radial truck tire, endpoint protection can be achieved, tire body endpoint stress is effectively dispersed, and early damage to tire body endpoints is avoided.
本发明涉及轮胎技术领域,尤其涉及一种全钢子午线载重轮胎,包括:三角胶芯、胎体帘布层、外子口加强帘布层、内子口加强帘布层以及外纤维帘布层;胎体帘布层包裹于三角胶芯外部,上端端头包覆有第一保护层;外子口加强帘布层设于胎体帘布层位于胎圈结构外侧方位的部分远离三角胶芯的一侧表面,上端端头包覆有第二保护层;内子口加强帘布层设于胎体帘布层位于胎圈结构内侧方位的部分远离三角胶芯的一侧表面,上端端头包覆有第三保护层;外纤维帘布层设于外子口加强帘布层远离胎体帘布层的一侧,上端端头高于外子口加强帘布层。该全钢子午线载重轮胎可以实现端点保护,有效分散胎体端点应力,避免胎体端点的早期损坏。
