Tire tread of cargo truck

Abstract

The invention relates to a truck tire, in particular to a tire tread pattern structure of a truck tire. A tire tread of a cargo truck comprises a central longitudinal circumferential pattern groove which is arranged at the position of a longitudinal center line of the tire tread and enables the tire tread to be evenly divided into two symmetrical parts in a left-right mode. Side part pattern blocks and tire shoulder pattern blocks are sequentially arranged on two sides of the central longitudinal circumferential pattern groove form interior to exterior. The side part pattern blocks and the tire shoulder pattern blocks are separated by an auxiliary longitudinal circumferential pattern groove. Each two adjacent side part pattern blocks along the circumferential direction are separated by an auxiliary pattern groove. The central longitudinal circumferential pattern groove and the auxiliary longitudinal circumferential pattern groove are respectively in a wave shape. Two ends of each auxiliary pattern groove are respectively communicated with the central longitudinal circumferential pattern groove and the auxiliary longitudinal circumferential pattern groove. The side part pattern blocks on two sides of the central longitudinal circumferential pattern groove are in point symmetry and arranged in a vertically staggered mode. The tire shoulder pattern blocks are integral pattern blocks. According to the tire tread of the cargo truck, mixed patterns are adopted. The tire tread of the cargo truck has sufficient braking force and good operational properties, and is attractive.

Description

technical field [0001] The invention relates to an automobile tire, in particular to a tread pattern structure of an automobile tire. Background technique [0002] There are many truck tire patterns in the prior art, which are generally divided into driving patterns, guiding patterns and trailer patterns. The design of tire tread pattern generally adopts the combination of horizontal pattern and longitudinal pattern. In addition to the wear resistance, grip, drainage and other performances, the design of the pattern should also consider the aesthetics of the tire, and require the tire to have a stable Starting and braking performance. Studies have shown that under the same conditions, the wear resistance and braking performance of the transverse pattern is better than that of the longitudinal pattern; however, the lateral slip of the transverse pattern is greater than that of the longitudinal pattern, and the fuel consumption of the transverse pattern is large, and it is ea...

Studies have shown that under the same conditions, the wear resistance and braking performance of the transverse pattern is better than that of the longitudinal pattern; however, the lateral slip of the transverse pattern is greater than that of the longitudinal pattern, and the fuel consumption of the transverse pattern is large, and it is easy to fall quickly
