Pneumatic tire tread structure for uneven ground

Abstract

The invention discloses a tread structure of a pneumatic tire for uneven ground. The tire tread is composed of several pattern units uniformly distributed along the tire circumferential direction, wherein each pattern unit includes Two symmetrical △-shaped pattern block groups, each △-shaped pattern block group spans the center of the tire tread, and each △-shaped pattern block group is formed by a V-shaped main groove across the tire tread center; each △-shaped pattern block group is formed by The auxiliary groove is divided into irregular central pattern block, transition pattern block, spacer pattern block and shoulder pattern block; the center pattern block spans the centerline of the tire tread; and the transition pattern block and spacer pattern block are located between the shoulder area and the tire between the center of the face; the shoulder blocks are located at the tire shoulders. By reasonably setting the tread block and its corresponding mud discharge channel, the traction performance of the tire during driving on uneven ground can be effectively improved, and sufficient comfort can be ensured at the same time.

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.
