Mining pattern of load meridian automobile tire

Abstract

The invention discloses a mining pattern of a load meridian automobile tire. The mining pattern comprises pattern grooves, wherein pattern blocks are formed among the pattern grooves; each pattern groove comprises tire shoulders at the two sides of a center line of a tread, and a left long oblique pattern groove and a right long oblique pattern groove which are formed in a staggered way at an interval on a crown; the inner ends of the corresponding left long oblique pattern grooves and right long oblique pattern grooves are connected with each other by reversed short oblique pattern grooves; the midpoints of the short oblique pattern grooves are positioned on the center line of the tread; the outer ends of all the long oblique pattern grooves horizontally extend to the side walls of the tire from the tire shoulders; the adjacent long oblique pattern grooves formed in the tire shoulder and the crown which are positioned at the same side are connected by longitudinal short pattern grooves. The mining pattern of the load meridian automobile tire is powerful in road holding, enough in rigidity, less in creep temperature rise, good in heat dispersion and long in service life.

Description

technical field [0001] The invention relates to an engineering machinery tire structure, in particular to a mine-used pattern for a load radial automobile tire. Background technique [0002] Due to factors such as heavy load bearing, large traction force, and complex road conditions, the tread of radial tires usually adopts different types of patterns in order to take into account the requirements of grip, wear resistance, and heat dissipation. structure to suit its performance requirements. [0003] For example, the tread pattern of the most common mine-used radial vehicle tire adopts wavy pattern grooves, which are arranged at intervals in the transverse direction (the axial direction of the tire) on the tread surface and divide the tread into uniformly distributed circles. Tread blocks, this kind of truck radial tire has the following defects found in use: [0004] 1. The direction of the pattern groove is more in the horizontal direction and less in the vertical direct...

AI Technical Summary

Problems solved by technology

[0004] 1. The direction of the pattern groove is more in the horizontal direction and less in the vertical direction, which makes the lateral grip of the tire insufficient and easy to slip

[0005] 2. Each pattern block is relatively independent and has a large area, which is easy to creep and cause temperature rise and slow heat dissipation, which makes the tire easy to age

[0006] 3. It is easy to get stuck in the groove of foreign matter and not easy to discharge, easy to damage the tread
