Abrasion wear mark of truck tire with zigzag tread pattern

Abstract

The invention relates to a wear indicator for a flexuose flower pattern loading automobile tyre, which is characterized in that the shape of the novel wear indicator is designed, namely the wear indicator consists of cylindrical rubber columns; the rubber columns are positioned on the groove bottom of a flower pattern groove, and the arrangement direction of the rubber columns is as same as the flower pattern direction; and the number of the rubber columns of each group of the wear indicator is between 3 and 5, the cylinder diameter (1) is between 1.5 and 1.8 mm, the space length of a cylinder (2) space is between 3 and 5 mm, and the cylinder height (3) is between 1.6 and 2.0 mm. Thus, the wear indicator can effectively prevent the flower pattern groove from deforming, reduce cracks of the wear indicator, avoid cracks at other positions, prolong the service life of the tyre and is particularly suitable to be used in the tyre industry.

Description

Technical field: [0001] The invention relates to a tire wear mark, in particular to a wear mark of a zigzag pattern truck tire. Background technique: [0002] At present, my country's regulations on truck tires require that each tire be equidistant along the circumference to set no less than 4 signs of the remaining depth of the pattern groove, 2.0mm for medium-duty and heavy-duty truck tires, 1.6mm for miniature and light-duty truck tires, and 1.6mm for miniature and light-duty truck tires. The wear marks of traditional zigzag pattern truck tires are usually blocks or several ridges connected to both sides of the groove wall. During use, due to the repeated bending and deformation of the pattern grooves, the wear marks become the concentrated points of force, which is easy to cause wear marks Cracks, which in turn cause cracks in other parts. Invention content: [0003] The purpose of the present invention is to provide a tire wear indicator with a zigzag pattern that can ...
