Embodiment 1

[0033] Example 1, an all-steel radial tire is made of a rubber steel wire reinforced material. Due to the viscoelasticity of the rubber material, it exhibits technical characteristics such as large deformation nonlinearity, temperature sensitivity, and easy thermal-oxidative aging. All-steel radial tires can be roughly divided into three parts: tread, sidewall and bead.

[0034] The present application is mainly aimed at making targeted improvements to the belt layer design and contour geometric features of the tread portion. At present, there are two main types of belt structures commonly used in China, namely, a four-layer belt stack structure, and a 0-degree belt layer + three-layer belt layer stack structure.

[0035] The present application is based on the existing technology, the 1# belt adopts a 90° carcass steel wire structure and supplements the comprehensive optimization configuration of the belt layer range and shoulder thickness, so as to increase the tire lateral ...

Abstract

The invention discloses an all-steel radial tire with 90-degree belt ply structures. According to the all-steel radial tire with the 90-degree belt ply structures, the layout design of belt plies on atire surface portion and the contour geometrical features are improved so that the lateral rigidity can be remarkably improved, a tire contact-to-ground print shape can be more reasonable, and grounding pressure can be uniformly distributed; the tire surface portion of the tire is provided with at least four layers of belt ply structures, a tire body approaching cord fabric and a 1 # belt ply onthe bottom layer each adopt a 90-degree tire body steel wire structure; as the above basic design concept, the 1 # belt ply adopts the 90-degree tire body steel wire structure, and is fused with a belt ply structure in the prior art so that the transverse rigidity and the aligning moment of the tire can be increased in a targeted mode, by improving the steering force of the tire, the transverse deformation of the tire surface can be reduced, moreover, the transverse expansion of a pattern groove can be inhibited, and eccentric wear and groove cracking of the tire can be reduced.

Description

technical field [0001] The invention relates to the improvement of the structure of an all-steel radial tire, and belongs to the field of rubber products and machinery manufacturing. Background technique [0002] At present, the performance requirements of rubber tires used in aviation, road and water transportation are getting higher and higher. Compared with traditional bias tires, all-steel radial tires have many advantages, such as wear resistance, fuel saving and handling stability. With rapid development and widespread popularity, it has become a mainstream product in the tire industry. In recent years, the increasing global requirements for green environmental protection have continuously promoted the development of tire manufacturing in the direction of fuel saving and emission reduction. Flat metric all-steel radial truck tires have become one of the main research directions. [0003] Flattened metric all-steel radial truck tires (also known as "wide-base all-steel...
