Pneumatic tire tread pattern structure for two-wheeled vehicle

Abstract

The invention discloses a pneumatic tire tread pattern structure for a two-wheeled vehicle. A tire tread comprises a plurality of inclined pattern main groove groups which are symmetrical with the center line of the tire tread and are arranged in a staggered manner; each inclined pattern main groove group comprises a first inclined pattern main groove and a second inclined pattern main groove which extend from a part, close to the center of the tire tread, to a tire shoulder in an inclined arc manner, and the arc shapes of the first inclined pattern main groove and the second inclined pattern main groove are arranged in a forward and reverse direction; each first inclined pattern main groove close to the center of the tire tread is in a downwards concave arc shape so as to be same with the rotation direction; each second inclined pattern main groove far from the center of the tire tread is in an upwards convex arc shape so as to be opposite with the rotation direction; the first inclined pattern main grooves and the corresponding second inclined pattern main grooves are in partial overlapping arrangement in the axial direction and the circumferential direction, so that a water discharging performance of a tire is ensured, edge constituents of the pattern grooves are increased, and dragging and braking performances are improved.

Description

technical field [0001] The invention relates to a tread pattern of a tire, in particular to a tread pattern structure of a pneumatic tire for a two-wheel vehicle. Background technique [0002] Such as figure 1 In the past, pneumatic tires for two-wheeled vehicles generally consisted of inclined longitudinal grooves 20' in order to ensure tire guiding and drainage performance. Each inclined longitudinal groove 21', 22' The surface extends obliquely to the shoulder area, and the oblique grooves are arranged in the same direction. But in this way, since the inclined grooves are set independently and in the same direction, the ground contact area between the inclined grooves is relatively large, and the edge components of the grooves are low. , unable to brake and drive normally and cause accidents, affecting the safety of travel. Based on the above problems, it is proposed to design an optimized tread pattern structure pattern of pneumatic tires for two-wheelers to improve t...
