Pneumatic tire tread structure for uneven ground

Abstract

The invention discloses a pneumatic tire tread structure for an uneven ground. The tire tread consists of a plurality of pattern units which are uniformly distributed along the circumferential direction of a tire, wherein each pattern unit comprises two triangular pattern block groups which are sequentially and axially symmetrically arranged along the center of the tire tread and the tire, and each triangular pattern block group stretches across the center of the tire tread, consists of main V-shaped grooves which stretch across the center of the tire tread, and is divided into irregular central pattern blocks, transition pattern blocks, spacing pattern blocks and shoulder pattern blocks by auxiliary grooves; the center pattern blocks stretch across the central line of the tire tread, and the transition pattern blocks and the spacing pattern blocks are positioned between a tire shoulder area and a tread central area; the shoulder pattern blocks are positioned at the tire shoulder. By reasonably arranging the tread pattern blocks and corresponding sludge discharge channels, the traction performance of tires on the uneven ground in the driving process can be effectively enhanced, and meanwhile, the adequate comfort can be ensured.

Description

technical field [0001] The invention relates to an all-terrain vehicle tire, in particular to a tread structure of an all-terrain vehicle pneumatic tire for running on uneven ground. Background technique [0002] With the overall development of the automobile market, all-terrain vehicles, as a new type of vehicle, are getting more and more attention from consumers, especially practical all-terrain vehicles. More and more sports-loving consumers regard it as the first choice for work and leisure sports. A practical all-terrain vehicle is a commonly used vehicle for work and leisure, and its common terrain is a neutral uneven road surface. In order to take into account the particularity of its use occasions, general all-terrain vehicle tires are often designed with a larger mud discharge channel on the tread pattern to prevent mud from clogging and achieve sufficient traction performance, but because of its low ground contact ratio, it is easy to This results in a decrease i...

Problems solved by technology

In order to take into account the particularity of its use occasions, general all-terrain vehicle tires are often designed with a larger mud discharge channel on the tread pattern to prevent mud from clogging and achieve sufficient traction performance, but because of its low ground contact ratio, it is easy to The comfort performance is reduced, and at the same time, the rigidity of a single pattern block is insufficient, and the phenomenon of pattern block creep is easy to occur during the driving and braking process of the vehicle, which affects the durability of the tread pattern, resulting in a tendency to decrease the traction performance of the tire.

Therefore, it is difficult for general all-terrain vehicle tires to combine traction and comfort well when driving on uneven ground to achieve comprehensive performance.
