Problems solved by technology

After the tire is inflated and stressed, the steel cords of the first, second and third belt layers are pulled in the circumferential direction of the tire, so that the filling rubber between the end points of the first belt layer and the second belt layer is easily affected. The shear force of the two layers of the belt layer is the first to be destroyed, resulting in shoulder empty tires, resulting in economic losses

Embodiment Construction

[0010] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] Such as figure 1 The all-steel load-bearing radial tire with zero-degree belt structure shown, the all-steel load-bearing radial tire includes a crown 6, a belt layer, a shoulder pad rubber 7, a carcass ply 8, an inner liner 9 and a sidewall 10, The belt layer is composed of the first belt layer 1, the second belt layer 2, the third belt layer 3 and the zero degree belt layer 4, between the ends of the first belt layer 1 and the second belt layer 2 Nylon fiber cord 5 is arranged between them, nylon fiber cord 5 is inserted between the ends of the first belt layer 1 and the second belt layer 2, and extends to between the second belt layer 2 and the shoulder pad rubber , the ends of the nylon fiber cord 5 are flush with the ends of the second belt layer 2 .

[0012] The applicant added nylon fiber cord 5 between the end po...

Abstract

The invention relates to an all-steel loading radial tire with a zero-degree belted layer structure, which comprises a tire crown, a belted layer, a tire shoulder pad compound, a tire body cord fabric, an inner lining layer and a tire side wall, wherein the belted layer comprises a first belted layer, a second belted layer, a third belted layer and a zero-degree belted layer, and a fiber cord fabric is arranged between end parts of the first belted layer and the second belted layer. In the invention, the fiber cord fabric is made by applying rubber to fiber cord threads and has higher shearing resistance compared with pure rubber; and by additionally attaching the fiber cord fabric between the end parts of the first belted layer and the second belted layer, the damage of a tire shoulder part can be deferred and the service life of the tire can be prolonged.

Description

technical field [0001] The invention relates to an all-steel load-bearing radial tire with a zero-degree belt layer structure. Background technique [0002] The all-steel radial truck tire with zero-degree belt structure includes crown, belt layer, shoulder pad rubber, carcass ply, inner liner and sidewall, and the belt layer consists of the first belt layer, the second belt layer , The third belt layer and the zero-degree belt layer, the steel cords of the first, second and third belt layers are arranged crosswise to form a network structure, and there is a belt filling between the ends of the first and second belt layers glue. After the tire is inflated and stressed, the steel cords of the first, second, and third belt layers are pulled in the circumferential direction of the tire, so that the filling rubber between the ends of the first belt layer and the second belt layer is easily affected. The shear force of these two layers of belt layers is the first to be destroye...
