The invention discloses an industrial vehicle tire using a rubber reinforcing part on outside of a bead. The industrial vehicle tire comprises a tire body, a tire main cord fabric layer is arranged onthe inner wall of the tire body, and a tire main cord fabric layer turn-up part is arranged at the edge of the tire main cord fabric layer; a tire bead filler, a steel wire ring and a tire bead constraint reinforcing part are arranged on the inner side of the tire main cord fabric turn-up part, the tire bead constraint reinforcing part is spirally wound on the steel wire ring in a wrapping mode,a reinforcing assembly is arranged on the outer side wall of the tire main cord fabric turn-up part, and the part, making contact with the ground, of the tire body is a tire crown. The inner wall of the tire crown is provided with a belt beam layer assembly. According to the industrial vehicle tire, the thickness of the tire bead filler is moderate, secondary molding is not hindered, the quality control cost in the production and storage processes of parts and the manufacturing process of a green tire can be reduced, and the crescent-shaped rubber reinforcing part is added to the outer side ofthe turn-up part of the main cord fabric layer of the tire. The hardness is higher than that of sidewall rubber and the heat generation is lower than that of the sidewall rubber, so that the bead part heat generation problem can be controlled.
本发明公开了一种胎圈外侧使用橡胶增强件的工业车辆轮胎,包括轮胎本体,轮胎本体的内壁设置有轮胎主帘布层,轮胎主帘布层的边缘处设置有轮胎主帘布层反包部,轮胎主帘布层反包部内侧设置有胎圈填充料、钢丝圈以及胎圈约束增强件,胎圈约束增强件螺旋缠绕包裹在钢丝圈上,轮胎主帘布层反包部的外侧壁上设置有增强组件,轮胎本体与地面相接触的部分为胎冠,胎冠的内壁上设置有带束层组件,本发明中,胎圈填充料厚度适中,不会对二次法成型带来阻碍,可降低部件生产、存储过程以及生胎制造过程中的品控成本,本发明在轮胎主帘布层反包部外侧外侧添加新月形的橡胶增强件,硬度高于胎侧胶且生热低于胎侧胶,可控制胎圈部生热问题。
