Pneumatic tire tread pattern structure for motorcycle

Abstract

The invention discloses a pneumatic tire tread pattern structure for a motorcycle, and relates to the technical field of tires, the pneumatic tire tread pattern structure is composed of a plurality of inclined pattern groove groups, the inclined pattern groove groups are symmetrically and uniformly arranged along the left side and the right side of a tread center line in a staggered mode, and the inclined pattern groove groups are arranged in the circumferential direction of the tire at intervals; the inclined pattern groove group comprises a main pattern groove, a first auxiliary pattern groove, an auxiliary pattern groove and a second auxiliary pattern groove, and the main pattern groove, the first auxiliary pattern groove, the auxiliary pattern groove and the second auxiliary pattern groove obliquely extend in an arc shape from the position close to the center of the tread to the tire shoulder and are sequentially connected. After the technical scheme is adopted, the wear resistance of the tire can be ensured, the drainage performance of the tire in a wet road condition in which the rainfall is changed from shallow to deep can be improved when the tire is driven on a rainy road condition, and the wet ground gripping performance of the tire is effectively improved.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a tread pattern structure of a pneumatic tire for motorcycles. Background technique [0002] With the continuous change of the motorcycle market, especially the heavy machine market, in addition to the continuous increase in the displacement of the vehicle, it has been continuously upgraded from the previous ordinary road vehicle to the track vehicle, and at the same time the requirements for the road conditions are also constantly changing. The use of pure dry land and pure wet road conditions is changed to dry and wet road conditions. For large-displacement motorcycle tires, the larger the displacement, the higher the driving speed, especially for wet tires. In order to improve the safety of pedestrians, the performance requirements of tires are also relatively strict. The previous tires only focused on the wet grip performance of shallow water roads to the wet grip performance o...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 As shown, in the past motorcycle tires, in order to ensure tire wear performance and improve drainage performance, the tire tread is composed of a plurality of main and auxiliary inclined grooves, including main groove 10', two auxiliary grooves 11', 12', The pattern grooves are set in the same direction and are set independently. They all extend obliquely from the tread to the shoulder, which can ensure the wet grip performance of the tire when driving in shallow water wetlands. When the shallow water volume is converted to deep water volume, the drainage space of this style tire Limited, insufficient driving force, unable to effectively break the water film, prone to tire idling or skidding, affecting the personal safety of riders
