Abstract

The invention relates to a structural design technology of an all-steel radial ply tire, in particular to the adjustment of the zero degree belt structure of the all-steel radial ply tire; the all-steel radial ply tire with zero degree belt structure comprises a tire face, a tire side, a tire ring and a cord ply; the exterior of the cord ply is sequentially 1# belt, 2# belt and zero degree belt; wherein, the 1# belt is wider than the zero degree belt; the grade difference between the 1# belt and the zero degree belt is at least 3mm. The invention breaks through the restrict of western design originator Pirelli SpA design conception on the zero degree belt structure, and provides an improved zero degree belt structure; namely, the zero degree belt is wider than the 1# belt; as the grade difference of the belt is increased, the stress is reasonably dispersed, in particular the shearing stress between ends of the 1#belt and 2# belt and the strain energy of the belt end region are reduced; the invention greatly improves the durability of the tire and reduces the shoulder vacancy defect of the tire.

Description

technical field [0001] The invention relates to the structural design technology of the all-steel radial tire, in particular to the adjustment of the 0-degree belt layer structure of the all-steel radial tire. Background technique [0002] With the upgrading of tire industry technology, all-steel radial tires have become the mainstream products in the tire industry. The main problems in the use of all-steel radial tires are the shoulder and bead problems, which are usually called "two-end point" problems and are worldwide. Difficult problems have become a sign that major tire companies at home and abroad are committed to solving and demonstrating their technological advancement. For example, improving shoulder defects by reducing tread heat generation is one of the measures. However, reducing tread heat generation often leads to a decrease in tire wear performance and sacrifices tire service life. [0003] Such as figure 1 As shown, the 0-degree belt structure design, as t...
