Description

Truck tire tread

technical field

The utility model belongs to the technical field of tires, in particular to a tread pattern structure of a truck tire.

Background technique

Due to the continuous improvement of the performance of existing automobiles and the popularization and application of radial tires, the performance requirements of tires are further improved, especially at high speeds, the handling stability, ground adhesion, driving safety, fuel saving, and durability of automobiles are greatly affected. Grinding and low noise have put forward higher requirements. Therefore, the design of the pattern plays a vital role in the performance of the tire. There are many truck tire patterns in the prior art, which are generally divided into driving patterns, guiding patterns and trailer patterns. The design of tire tread pattern generally adopts the combination of transverse pattern and longitudinal pattern. The designed pattern needs to consider the performance of wear resistance, grip, drainage and other properties, and requires the tire to have stable starting and braking performance. At present, the market requires automobile tires to be green and environmentally friendly. Domestic and foreign tire manufacturers have conducted a lot of research on pattern design in order to achieve excellent performance such as low noise, low rolling resistance, high safety performance, and long service life. When designing a tire tread, the tread designer uses a combination of blocks and grooves in order to optimize the tire's tread performance.

Technical research shows that under normal circumstances, the longitudinal pattern has good guiding and drainage performance, low noise and low rolling resistance when driving at high speed; the driving performance and braking performance of the transverse pattern are better than that of the longitudinal pattern; the lateral slip of the transverse pattern It is larger than the longitudinal pattern, and the noise of the transverse pattern is high and the rolling resistance is large; the mixed pattern has the advantages of the above two patterns. In order to ensure the comprehensive performance of the tire, the transverse pattern and the longitudinal pattern are often used together. Compared with light vehicles such as cars, trucks have higher requirements on the control ability of the road surface and the degree of tread wear. The use of pattern blocks or grooves in the tread can be determined by the end use of the tire. When designing the tread pattern, factors such as the road conditions, load capacity, driving speed, and weather conditions of the tire should be fully considered. Therefore, how to develop a new type of truck tire tread, so that it has more comprehensive performance, has important practical significance.
