Embodiment 1

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

[0034] This application is mainly aimed at improving the design of the belt layer of the tread and the geometrical features of the contour. At present, there are mainly two types of belt layers that are more common in China, namely, a four-layer belt stack structure, and a 0-degree belt layer + three-layer belt layer stack structure.

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

Abstract

The all-steel radial tire with a 90-degree belt structure according to the present invention improves the belt layer layout design and contour geometric features of the tread part, so as to significantly improve the lateral rigidity, and the shape of the tire footprint is more reasonable , Evenly distributed grounding pressure. The tire tread part is provided with a belt layer structure of at least 4 layers. The 1# belt layer close to the carcass cord and the bottom layer adopts a 90° carcass steel wire structure. According to the above basic design concept, the 1# belt layer adopts a 90° carcass steel wire structure, and integrates it with the existing technology belt layer structure, so as to increase the lateral rigidity and righting moment of the tire in a targeted manner. Its steering force can reduce the lateral deformation of the tread and restrain the lateral expansion of the groove, reducing the eccentric wear and groove cracking of the tire.

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 economy and handling stability. With rapid development and widespread popularization, it has become a mainstream product in the tire industry. In recent years, the global demand for green environmental protection has been increasing, which has 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] Flat metric all-steel radial truck tires (also known as "wide-base ...
