All Terrain Vehicle Pneumatic Tires

Abstract

The invention discloses a pneumatic tire for an all-terrain vehicle. A tire tread comprises a plurality of pattern units which are uniformly distributed in a circumferential direction of the tire, wherein each pattern unit comprises main pattern blocks and auxiliary pattern blocks, the main pattern blocks and the auxiliary pattern blocks are symmetrically and alternately arranged in the circumferential direction of the center of the tire tread in sequence, each group of the main and auxiliary pattern blocks extend from the center of the tire thread to tire shoulders on two sides, the head part of each main pattern block close to the center of the tire tread crosses the plane of the center of the tire tread, and a spacing distance is formed between the head part, close to the main pattern block, of the corresponding auxiliary pattern block and the main pattern block is formed; section contours of each group of the main and auxiliary pattern blocks located nearby the center of the tire tread are set as a main pattern block reduction arc and an auxiliary pattern block reduction arc with difference respectively, that is, the heights of the main pattern block and the auxiliary pattern block are reduced from the start ends of the main pattern block reduction arc and the auxiliary pattern block reduction arc to the inner end edge, crossing the plane of the tire tread, of the main pattern block. Therefore, the controllability of the tire traveling on off-road terrain can be improved while the traveling comfort of the tire is effectively guaranteed.

Description

technical field [0001] The invention relates to a tire tread profile and pattern structure, in particular to an all-terrain vehicle pneumatic tire used on off-road roads. Background technique [0002] At present, the domestic all-terrain vehicle market is developing rapidly, because all-terrain vehicles can be driven on various terrains such as mud, hard ground, woodland, sandy ground, etc. More and more consumers are keen on this new multi-functional vehicle. In recent years, driving all-terrain vehicles under muddy terrain has also become a new entertainment item. Most enthusiasts need to enter the muddy terrain to participate in entertainment competitions after driving on normal off-road roads. All-terrain vehicle tires driving on muddy terrain are prone to mud gathering at the bottom of the tire tread block, which will reduce the depth of the tread pattern, reduce the original traction performance of the tread pattern, and increase the weight of the tire, which will affe...

AI Technical Summary

Problems solved by technology

Under the combined action of the two, the tires are prone to deflection during driving, resulting in a decrease in tire handling, and also prone to circumferential ground jumping, which affects the driving comfort of the vehicle.

[0004] For example, the concave tread profile disclosed in the Chinese utility model patent with the application number CN201320466368.8 mainly has a central groove penetrating in the circumferential direction at the position of the center surface of the tread pattern, which still needs to be formed after inflation. The concave tread profile forms a certain drainage space. This design is mainly to improve the drainage of the tire and prevent cracks and partial wear at the bottom of the center groove, but it has no direct effect on the stability of the tire.
