The invention relates to an off-highway all-steel radial tire for load-carrying engineering machinery. The belted layer structure of the novel structure is composed of five layers of wirecord fabrics, a first layer of wirecord fabric is arranged on a tire body in an attached mode, the included angle between the first layer of wirecord fabric and the center line of a tire tread is 23 +/-1 degrees, a second layer of wirecord fabric is arranged on the first layer of wirecord fabric in an attached mode, the included angle between the second layer of wirecord fabric and the center line of the tire tread is 17 +/-1 degrees, a third layer of wirecord fabric and a fourth layer of wirecord fabric are sequentially and circumferentially arranged on the second layer of wirecord fabric in a laminated manner in a manner that the included angle between the third layer of wirecord fabric and the center line of the tire tread is 0 degree and the included angle between the fourth layer of wirecord fabric and the center line of the tire tread is 0 degree, a fifth layer of wirecord fabric is arranged on the fourth layer of 0-degree wirecord fabric, and the included angle between the fifth layer of wirecord fabric and the center line of the tire tread is 40 +/-1 degrees. Compared with the prior art, the structure provided by the invention can effectively relieve the phenomena of shoulder gaps, crown gaps and the like caused by large heat generation of the tire due to the deformation of the tire after long-term bending deformation in a heavy-load state of the tire.
本发明涉及非公路型全钢载重工程机械子午线轮胎,该新型结构的带束层结构由5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23±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17±1°,第三层钢丝帘布和第四层钢丝帘布采用与轮胎胎面中心线之间的夹角为0°的方式依次周向层贴排列在第二层钢丝帘布上,第五层钢丝帘布层贴排列在第四层0度钢丝帘布上,其与轮胎胎面中心线之间的夹角为40±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。
