The invention discloses a semi-steel radial tire capable of improving tire bead separation. The semi-steel radial tire comprises a tire crown, the tire side wall comprises a tire side wall rubber layer, a tire side wall filling layer and a reinforcing body; the tire bead comprises a tire bead steel wire and a tire bead filling body; the tire body comprises a tire body rubber layer and a tire body filling layer; and the reinforcing body is embedded in the sidewall filling layer and is opposite to the tire bead filling body. On one hand, by arranging the tire body rubber layer and the tire body filling layer, the tire bead can be wrapped in the tire body, so that the condition that the tire bead is easy to deform or is separated from the tire body and the tire side wall when being stressed is improved; on the other hand, the tire sidewall rubber layer and the tire sidewall filling layer are arranged, so that the tire bead steel wire and the tire bead filling body can be protected from the outer side of the tire, and the condition that the tire bead is easy to deform or is separated from the tire body and the tire sidewall when being stressed is further improved; and finally, the reinforcing body and the tire bead filling body are oppositely arranged, so that the condition that the tire bead is easy to deform or is separated from the tire body and the tire side wall when being stressed can be further improved.
本申请公开了一种改善胎圈分离的半钢子午胎,包括胎冠;胎侧,胎侧包括胎侧橡胶层、胎侧填充层和增强体;胎圈,胎圈包括胎圈钢丝和胎圈填充体;胎体,胎体包括胎体橡胶层和胎体填充层;增强体嵌设于胎侧填充层内并与胎圈填充体相对设置。本申请在一方面,通过设置胎体橡胶层和胎体填充层,能够将胎圈包覆于胎体中,从而改善胎圈受力时易变形或与胎体和胎侧分离的情况;另一方面,通过设置胎侧橡胶层和胎侧填充层,能够从轮胎外侧对胎圈钢丝和胎圈填充体进行保护,进一步改善胎圈受力时易变形或与胎体和胎侧分离的情况;最后,增强体与胎圈填充体相对设置,能够更进一步地改善胎圈受力时易变形或与胎体和胎侧分离的情况。
