Summary of the invention
The purpose of this utility model is: a kind of whole steel wire radial tyre that adopts strengthening type three-layered steel belt structure is provided, it has avoided the existence of zero-degree belt structure overlapped joint, can make tire shoulder intensity be greater than the tire of common three layers of belt structure, the long-distance endurance quality of tire and overload performance are had to very big improvement, to overcome the deficiencies in the prior art.
The utility model is achieved in that the whole steel wire radial tyre that adopts strengthening type three-layered steel belt structure, comprise the carcass ply of tire and be arranged on the bracing ply member on carcass ply, the 1# bracing ply of bracing ply member is directly fitted on carcass ply; On 1# bracing ply, be fitted with 2# bracing ply; Above the both sides of 2# bracing ply, be wound around symmetrical 3# bracing ply, the circumferential enhancement layer that 3# bracing ply is spiral winding, the circumferential angle of the steel wire of 3# bracing ply and tire is less than or equal to 1 °, and the outer end of 3# bracing ply is no more than the outer end of 2# bracing ply; On 3# bracing ply, be fitted with 4# bracing ply, the outer end of 4# bracing ply exceedes the inner of 3# bracing ply, but does not exceed the outer end of 3# bracing ply, and the part exceeding covers on 3# bracing ply.
Described 1# bracing ply is that the severing of steel wire calendaring cord is made, and the circumferential angle of steel wire and tire is 15 °～90 °.
Described 2# bracing ply is that the severing of steel wire calendaring cord is made, and the circumferential angle of steel wire and tire is 15 °～90 °.
Described 3# bracing ply is taking the 1-3 root steel wire that is arranged parallel to each other as one group, and continuous helical is wrapped on 2# bracing ply, and the stretch ratio of steel wire is 2%～8%, and Steel Wire Surface is all covered with rubber.
Described 4# bracing ply is that the severing of steel wire calendaring cord is made, and the circumferential angle of steel wire and tire is 15 °～90 °, and the outer end of 4# bracing ply exceeds the inner 5～30mm that strengthens bracing ply.While avoiding tyre rebuilding, enhancement Layer steel wire is polished at random.
Owing to having adopted technique scheme, compared with prior art, the utility model improves existing three layers of belt structure, adopt this structure can increase tire shoulder intensity, reduce shoulder material, reduce shoulder shearing stress, reduce the generation of the empty phenomenon of shoulder, and can increase the intensity of taking turns crown part, and increase shock resistance and the endurance quality of tire, reduce hat sky, be preced with quick-fried occurrence probability; Make tire performance aspect long-distance durable, high speed performance more excellent.The utility model combines the advantage of zero-degree belt structure and three layers of belt structure, avoid the existence of zero-degree belt structure overlapped joint, tire shoulder intensity is greater than the tire of common three layers of belt structure, and the long-distance endurance quality of tire and overload performance are had to very big improvement.The utility model novel structure, result of use is good.
