Problems solved by technology

The main feature of this kind of all-steel wire radial truck tire is that it can improve the rigidity of the tire shoulder, prevent the deformation of the end of the belt layer, reduce the heat generation of the tire shoulder, and improve the load-carrying capacity of the tire, which is more suitable for medium and short distances with large cargo capacity. Transportation and use on ordinary mixed roads; its disadvantage is that it is not suitable for medium and long-distance road high-speed transportation because it is prone to bulges and cracks at the tire mouth

Embodiment Construction

[0010] As shown in the figure: on the cross-section of the annular tire, the inner wall of the tire is an airtight layer 5, the outer wall of the tire is a tread 1 with a pattern, and the inner wall of the tire is bent into an open cavity that can accommodate the inner tube. The edge of the tire shrinks inwardly, and a steel ring 6 is buried on the edge of the inner wall. From the airtight layer 5 of the tire to the tread 1, there are steel wire carcass 4, four-layer steel wire belt layer 3, and transition rubber layer 2.

[0011] Tread 1 wherein is positioned at the outermost of tire, mainly provides the adhesion force of tire to ground. The transition rubber layer 2 is the lower layer of the tread, which has the characteristics of low heat generation and is used to improve the high-speed and durability performance of the tire. The steel wire carcass 4 is the radial structure of the tire, which can improve the safety performance of the carcass when the tire is used continuous...

Abstract

The invention relates to a four-layer steel belt tyre, belonging to the vehicle tyre technique. The inner wall of tyre on the section of circular tyre is airtight layer; the outer wall is the tyre surface with pattern; the inner wall can be bended to form a open chamber to contain the inner tyre; and the edge of inner wall can retract and have steel ring embedded in it. The invention is characterized in that: the steel wire tyre, the four-layer steel belt layer, and transition rubber layer are sequentially arranged between airtight layer and the tyre surface. The invention via enlarging the driving surface can increase the volume of inner chamber to increase the grounding area, improve the operation stability and reduce the rolling resistance of tyre.

Description

technical field [0001] The present invention relates to automobile tires, in particular to a tire with a four-ply structure. Background technique [0002] Most of the existing car tires are all-steel wire radial truck tires with a 0° belt structure. The belt layer of this tire has three layers, and the third layer of belt layer reduces the width and is placed in the center of the crown. There are double-layer narrow strips on both sides of the belt layer, and the belt layer is arranged at 0° at an angle parallel to the crown centerline, so it is sometimes called 0° belt layer. The main feature of this kind of all-steel wire radial truck tire is that it can increase the rigidity of the tire shoulder, prevent the deformation of the end of the belt layer, reduce the heat generation of the tire shoulder, and improve the load-carrying capacity of the tire, which is more suitable for short- and medium-distance large-cargo loads. Transportation and use on ordinary mixed roads; its...
