Tire tread pattern structure of all-terrain vehicle pneumatic tire

Abstract

The invention discloses a tire tread pattern structure of an all-terrain vehicle pneumatic tire. A tire tread comprises a left circumferential bar-shaped pattern column and a right circumferential pattern column which are symmetrically arranged along a central plane of the tire and are respectively formed by discontinuous left pattern blocks and discontinuous right pattern blocks in circumferential arrangement, and the left pattern blocks and the right pattern blocks are arranged in a staggered manner, wherein distances from the left pattern blocks and the right pattern blocks to the central plane of the tire are 7%~15% of the width of a tire section; the ground surfaces of the left pattern blocks and the right pattern blocks respectively consist of constant altitude parts positioned at a first ground end, and convergent parts which are positioned at later ground ends and are formed by contracting the constant altitude parts to the bottoms of pattern grooves; at the same time, concave arrangement is formed in the side walls of the first ground ends. Through the arrangement, the tire last is not influenced, and at the same time, the control performance of the tire on the sandy land can also be improved.

Description

technical field [0001] The invention relates to a tread pattern structure of a pneumatic tire, in particular to a tread pattern structure of an all-terrain vehicle pneumatic tire used on sandy ground. Background technique [0002] At present, the domestic all-terrain vehicle market is developing rapidly, and more and more consumers are keen on this multi-functional new model, and driving all-terrain vehicles under sand dunes and desert terrain has become a new entertainment item. When an all-terrain vehicle is driving on sand dune terrain, because the sand particles are relatively soft, it is difficult for the tires to gather to provide corresponding traction, resulting in poor handling of the tires, especially in the front wheels. light phenomenon. In order to improve the poor handling of the front wheels, the commonly used tire tread pattern structure is an asymmetrical circumferential stripe pattern design, such as figure 1 As shown, the circumferential stripe-shaped le...

When an all-terrain vehicle is driving on sand dune terrain, because the sand particles are relatively soft, it is difficult for the tires to gather to provide corresponding traction, resulting in poor handling of the tires, especially in the front wheels. light phenomenon

In order to improve the poor handling of the front wheels, the commonly used tire tread pattern structure is an asymmetrical circumferential stripe pattern design, such as figure 1 As shown, the circumferential stripe-shaped left tread row 10' and the circumferential stripe-shaped right tread row 20' are designed asymmetrically along the center plane of the tire. When the tire is installed, the circumferential stripe-shaped left tread row 10' and the circumferential stripe-shaped The right pattern row 20' is arranged on the inner side of the axial direction. At the same time, the characteristics of the shock absorber system of the all-terrain vehicle can be used to increase the driving responsiveness. However, when it is used on a high-load all-terrain vehicle, due to the high load of the vehicle, the tire The grounding area on the axially outer side of the tire is enlarged. At this time, because of the lack of effective grounding tread pattern design on the axially outer side of the tire, its handling performance is not good.

In addition, in order to improve the corresponding sand removal effect, the circumferential stripe pattern is often divided into discontinuous pattern blocks, such as figure 1 , figure 2 As shown, this design can form interpenetrating sand discharge spaces to enhance the sand discharge ability of the tire when turning. However, because the first ground contact end of the tire is designed with a larger tread block root, when the tire is running, the first ground contact end cuts into the sand. The increased resistance makes it impossible for the pattern block to quickly and effectively cut into the sand, and it is also prone to poor handling responsiveness
