Problems solved by technology

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

Embodiment Construction

[0014] The tread of a truck tire includes a central pattern block 1 arranged at the center of the tread, and a central longitudinal circumferential groove 3 is arranged in the middle of the central pattern block 1, and the central longitudinal circumferential groove 3 divides the tire tread into left and right symmetrical sections. Two parts; the central pattern block 1 is provided with auxiliary pattern grooves 2 at intervals; the left and right sides of the central pattern block 1 are respectively provided with shoulder pattern blocks 5; the central pattern block 1 and the shoulder pattern blocks 5 pass through longitudinal circumferential pattern grooves 4 intervals, the shoulder pattern blocks 5 are in an integral structure.

[0015] Both the central longitudinal circumferential groove 3 and the circumferential groove 4 adopt a zigzag structure. Bottoms of the central longitudinal circumferential groove 3 and the circumferential groove 4 are provided with protrusions 6 , a...

Abstract

The invention relates to a tire structure for an automobile, in particular to a tread pattern structure of a load-carrying automobile tire. A tire tread for a load-carrying automobile comprises central pattern blocks which are arranged at the central position of the tread, wherein central longitudinal circumferential pattern grooves are formed in the middle of the central pattern blocks, and are used for dividing the tire tread into a left part and a right part which are symmetrical to each other; auxiliary pattern grooves are formed on the central pattern blocks at intervals; the left and right sides of each central pattern block are provided with a tire shoulder pattern block respectively; the central pattern blocks are spaced from the tire shoulder pattern blocks through the longitudinal circumferential pattern grooves; and the tire shoulder pattern blocks have an integrated structure. Mixed patterns are used for the tread of the tire, and have sufficient braking force, high maneuvering performance and aesthetic and elegant appearance.

Description

technical field [0001] The invention relates to an automobile tire structure, in particular to a tread pattern structure of a truck tire. Background technique [0002] Due to the continuous improvement of the performance of existing automobiles and the popularization and application of radial tires, the performance requirements of tires are further improved, especially at high speeds, the handling stability, ground adhesion, driving safety, fuel saving, and durability of automobiles are greatly affected. Grinding and low noise have put forward higher requirements. Therefore, the design of the pattern plays a vital role in the performance of the tire. 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 performanc...
