Tread pattern structure of radial tire

Abstract

A radial tire tread pattern structure, which includes at least one zigzag central groove arranged along the tire tread circumferential direction and located at the center of the tread, and a second groove located on both sides of the central groove and arranged along the tire tread circumferential direction. Two main grooves; side pattern blocks are formed between the central pattern groove and the second main groove, and sipe grooves are arranged on the side pattern blocks; shoulder pattern blocks are formed between the second main groove and the tire sidewall, Adjacent pattern blocks on both sides are spaced by inclined side pattern grooves, and the two ends of the side pattern grooves are respectively connected to the central pattern main groove and the second main groove; while the shoulder pattern blocks are longitudinally arranged along the tire circumferential direction. One-piece pattern blocks, with transverse sipe grooves arranged on the shoulder pattern blocks. This tread pattern structure not only meets the requirements of tire load resistance and wear resistance, but also takes into account the tire's comprehensive performance such as wet performance and anti-stone trapping, so as to ensure the safety and service life of the tire.

Description

technical field [0001] The invention relates to an automobile tire structure, in particular to an automobile radial tire tread pattern structure. Background technique [0002] As we all know, the tread pattern of the tire plays a very important role in the performance of the tire, and the performance of the tread pattern is easy to influence each other and restrict each other. When designing the tread pattern, it should be designed according to different vehicle types and service conditions. Different vehicle types have different requirements for tire performance and focus. [0003] The truck has a heavy load, and its pattern must have good traction performance. Whether it is on a dry or wet road, the safety of its driving must be guaranteed. In order to ensure the service life of the tire, the wear resistance of the tread must also be considered. This requires the designer to reasonably match the grooves and blocks in order to optimize the performance of the tread and achi...

AI Technical Summary

Problems solved by technology

Existing truck tires have many patterns, most of which are mainly based on load resistance and wear resistance. They are usually designed as large blocks, and the pattern grooves are designed laterally to meet the requirements of traction and wear resistance. However, this design not only reduces the handling performance , and it is difficult to take into account the wet performance of tires, especially for light-duty trucks that have certain requirements for speed. Cracks the bottom of the ditch, reducing the service life of the tire
