The invention provides an all-steel truck radial tire. The belted layer structure of the tire is composed of four layers of wirecord fabric, the first wirecord fabric layer is arranged on the tire body in an attached mode, the included angle between the first wirecord fabric layer and the center line of the tire tread is 52 +/-1 degrees, the second wirecord fabric layer is arranged on the first wirecord fabric layer in an attached mode, the included angle between the second wirecord fabric layer and the center line of the tire tread is 15 +/-1 degrees, the third wirecord fabric layer is arranged on the second wirecord fabric layer, the included angle between the third wirecord fabric layer and the center line of the tire tread is 15 +/-1 degrees, the fourth wirecord fabric layer is arranged on the third wirecord fabric layer, and the included angle between the fourth wirecord fabric layer and the center line of the tire tread is 18 +/-1 degrees. Compared with the prior art, the structure provided by the invention can effectively relieve shoulder empty, crown empty and other diseases caused by large tire heat generation due to tire deformation caused by long-term bending deformation of the tire in a heavy load state.
本发明涉及一种全钢载重子午线轮胎,该轮胎的带束层结构由4层钢丝帘布组成,第一层钢丝帘布层贴排列在胎体上,其与轮胎胎面中心线之间的夹角为52±1°,第二层钢丝帘布层贴排列在第一层钢丝帘布上,其与轮胎胎面中心线之间的夹角为15°±1°,第三层钢丝帘布层贴排列在第二层钢丝帘布上,其与轮胎胎面中心线之间的夹角为15°±1°,第四层钢丝帘布层贴排列在第三层钢丝帘布上,其与轮胎胎面中心线之间的夹角为18°±1°。与现有技术相比,本发明结构可以有效缓解轮胎重载状态下长期曲饶变形后造成轮胎的形变,而带来的轮胎生热大产生的肩空和冠空等病象。
