Description

Technical Field

[0001] The utility model relates to the technical field of agricultural radial tires, in particular to a novel belt layer structure of an agricultural radial tire. Background Art

[0002] Currently, the belt layer of agricultural radial tires is made of polyester cord or steel belt layers arranged and laminated in a cross pattern. The durability of the tire determines its service life, and the shear force between the belt layer and the tread causes rapid heat generation, which is one of the factors that shortens the tire life. The belt layer is one of the key components of the tire. In addition to mitigating the impact, it mainly plays the role of tightening the tire body. For radial tires, it is also the main load-bearing component. When the shear force is too large, it can easily cause the belt layer endpoints (on both sides) to delaminate early, affecting the safety of the user. At present, the steel belt layer of most tires is wrapped with thin and soft rubber strips on both sides. The rubber strips are easy to loosen at the ends of the steel cords, causing localized rapid heat generation during driving, affecting driving safety. Utility Model Content

[0003] The purpose of the utility model is to provide a new belt layer structure for agricultural radial tires, which solves the problem that the steel belt layers of most tires now are wrapped with rubber strips on both sides. The rubber strips are thin and soft, and the ends of the steel cords are easy to loosen, resulting in rapid local heating during driving and affecting driving safety.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new belt layer structure of an agricultural radial tire, comprising a tread, wherein a belt layer 1 is provided at the upper end of the tread, a belt layer 2 is provided at the upper end of the belt layer 1, a belt layer 3 is provided at the upper end of the belt layer 2, a belt layer 4 is provided at the upper end of the belt layer 3, a mesh cloth 1 is provided at the upper end of the mesh cloth 1, a support layer is provided at the upper end of the mesh cloth 2, and a carcass is provided at the upper end of the support layer.

[0005] Preferably, the tread is composed of multiple layers of steel belts, which are pressed together with mesh cloth one and mesh cloth two, so that mesh cloth one and mesh cloth two can limit the positions of belt layer one, belt layer two, belt layer three and belt layer four.

[0006] Preferably, the belt layer 1 and the belt layer 2 are cross-pressed on the tread, which can make the belt layer 1 and the belt layer 2 pressed against the tread more stable.

[0007] Preferably, the support layer is pressed together with the belt layer 4, and the support layer is pressed together with the mesh cloth 1, which can fix the belt layer 1, the belt layer 2, the belt layer 3 and the belt layer 4 together and provide additional support and protection.

[0008] Preferably, the support layer is a carcass weft colloid, and the support layer is pressed together with the tread. The support layer can be used to enhance the connection and fixing performance of the tire and provide good adhesion and flexibility.

[0009] Preferably, the carcass is made of polyester fiber, and a buffer groove is provided inside the carcass. The design of the buffer groove can ensure stability between the carcass and the support layer.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. The utility model adds two layers of mesh cloth between the tread and the ends of multiple belt layers, and optimizes the belt layer structure. When the edge rubber strip is frosted or the size is not properly positioned, or the belt layer edge is loose, it can prevent friction between the tread and the belt layer, reduce heat generation, improve tire stability, reduce delamination caused by stress concentration in the shoulder area, and enable the tire to have good cornering performance when driving at high speeds, thereby improving tire life.

[0012] 2. The utility model is provided with a support layer, the material of which is a carcass weft colloid. The support layer has good adhesion and flexibility, can fix multiple belt layers together and provide additional support and protection, and by providing a buffer groove, can effectively increase the service life of the carcass.
