Off-road tyre with low tyre noise

Abstract

The invention discloses an off-road tyre with low tyre noise. According to the design principle of a low-noise tyre, pitches of tyre patterns are optimized, and are enlarged or narrowed so as to form five kinds of different pattern pitches, and specific permutation and specific combination are performed, so that the purpose of reducing the tyre noise is achieved; besides, pattern blocks are arrayed on the tyre in a stagger manner in the width direction and arranged on the tyre in an interlocked manner, so that an excellent edge effect can be realized, and pattern noise is reduced; five kinds of the different pattern pitches, namely a first pattern pitch a, a second pattern pitch b, a third pattern pitch c, a fourth pattern pitch d and a fifth pattern pitch e, are arranged in the circumferential direction of the tyre, ,are in a relationship that a / b is greater than or equal to 0.91 and smaller than or equal to1.28, b / c is greater than or equal to 0.94 and smaller than or equal to1.37, c / d is greater than or equal to 0.93 and smaller than or equal to 1.43, and d / e is greater than or equal to 0.85 and smaller than or equal to1.37; tyre crown pattern blocks and tyre shoulder pattern blocks are arrayed on the tyre in the stagger manner in the width direction, and the tyre shoulder pattern blocks and the adjacent tyre crown pattern blocks are arranged in the interlocked manner.

Description

technical field [0001] The invention relates to the technical field of off-road tires, in particular to an off-road tire with low tire noise. Background technique [0002] The common off-road tires currently sold in the domestic market are mainly to meet the basic requirements of automobiles on tires, that is, the performance requirements of tire load capacity, tire pressure, and tire size. Most of these products do not reduce tire noise. Put it first. Because in the past, there was no sufficient understanding of the noise of automobiles in China, so the noise of tires has not received due attention. However, with the rapid development of my country's economic construction and the improvement of people's living standards, people are paying more and more attention to tires with low noise. more attention. The pattern shape of the tire is repeated in the circumferential direction, and the length of a group of repeated patterns is called a pattern pitch. For the convenience of ...

AI Technical Summary

Problems solved by technology

The pattern shape of the tire is repeated continuously in the circumferential direction, and the length of a group of repeating patterns is called a pattern pitch. For the convenience of production, ordinary tires generally adopt an equal-pitch design. During the use of this kind of tire, it is easy to produce a larger pattern. loud tire noise

In addition, the pattern blocks on the tread of the tire are mostly designed with left and right symmetry, the effect of the edge of the pattern block is poor, and the tire noise is relatively large, and the traction and grip effect of the tire with the left and right symmetrical pattern blocks on off-road terrain is average.
