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

[0015] The tread of a truck tire includes a central longitudinal circumferential groove 1 set at the central position of the tread, that is, the center line CL of the tread. The central longitudinal circumferential groove 1 divides the tire tread into two symmetrical parts. The central longitudinal circumference On the left and right sides of the pattern groove 1, the side pattern blocks 2 and the shoulder pattern blocks 6 are regularly arranged in order from the inside to the outside, and the side pattern blocks 2 and the shoulder pattern blocks 6 are separated by a longitudinal circumferential groove 9. The pattern blocks 2 on both sides are separated by auxiliary pattern grooves 3 ; the shoulder pattern blocks 6 form an integral structure along the circumferential direction of the tire tread.

[0016] The side pattern blocks 2 are inclined "8"-shaped structures. The inclination angle of the side blocks 2 relative to the tread centerline CL is 20°. The side corner of the si...

Abstract

The invention relates to a tire tread of a motortruck, in particular to a tread pattern structure of a motortruck tire. The tire tread of the motortruck comprises a central longitudinal circumferential pattern groove which is arranged on the center of the tire tread, namely the center line of the tire tread, wherein, the central longitudinal circumferential pattern groove equally divides the tire tread into a left part and a right part which are symmetrical to each other; lateral pattern blocks and tire shoulder pattern blocks are sequentially arranged on both sides of the central longitudinal circumferential pattern groove from the inside out and are partitioned by the longitudinal circumferential pattern groove, and every two adjacent lateral pattern blocks are partitioned by an auxiliary pattern groove; and the tire shoulder pattern blocks form an integral structure along the circumferential direction of the tire tread. The tire tread of the tire adopts the mixed patterns, and has enough braking force, favorable maneuvering performance and shapely configuration.

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...
