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

[0016] The central position of the tire tread is provided with V-shaped grooves 2 at intervals along the circumferential direction, and the central pattern block 1, the shoulder pattern block 3, and the central pattern block are sequentially arranged along the direction of the groove wall of the V-shaped groove 2 from the bottom of the groove to the top of the groove. 1 and the shoulder pattern blocks 3 are separated by lateral grooves 4, and the two ends of the lateral grooves 4 are connected to two adjacent V-shaped grooves; the central pattern blocks 1 are stacked and staggered in sequence along the circumferential direction. The inclination direction of two adjacent central pattern blocks 1 is symmetrical with respect to the central position; two adjacent shoulder pattern blocks 3 are separated by lateral auxiliary grooves 5, and the lateral auxiliary grooves 5 communicate with V-shaped grooves 2 and transition smoothly .

[0017] Adjacent V-shaped grooves 2 communicate th...

Abstract

The invention relates to an automobile tire structure, in particular to a tread pattern structure of a load-carrying automobile tire. In a tread pattern for a radial ply tire of a sedan, V-shaped pattern grooves are formed at the central position of a tire tread along the circumferential direction at intervals; central pattern blocks and tire shoulder pattern blocks are arranged in the groove wall directions of the V-shaped pattern grooves from groove bottoms to groove tops sequentially; the central pattern blocks are spaced from the tire shoulder pattern blocks through lateral pattern grooves; the two ends of the lateral pattern grooves are communicated with two adjacent V-shaped pattern grooves; the central pattern blocks are arranged in a sequentially superposed and staggered way along the circumferential direction; the inclined directions of the two adjacent central pattern blocks are symmetrical to each other relative to the central position; every two adjacent tire shoulder pattern blocks are spaced from each other through a transverse pattern groove; and the transverse pattern grooves are communicated with the V-shaped pattern grooves and are smoothly transitioned. 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 a car tire structure, in particular to a tread pattern structure of a car tire. Background technique [0002] In the prior art, there are many car tire patterns, which are usually divided into driving patterns, guiding patterns and the like. 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 easy to fall quickl...
