Tread pattern structure of air-filled tyre used for motorcycle

Abstract

The invention discloses a tread pattern structure of an air-filled tyre used for a motorcycle. A tyre tread is composed of a plurality of pattern units which are symmetrical by taking the center line of the tread and are arranged in a staggered manner, wherein each pattern unit comprises two h-shaped pattern main channels which are arranged in the circumferential direction of the tread obliquely; the long edge of each h-shaped pattern main channel comprises a first folding line, a second folding line and a third folding line which extend from the center of the tread to the tyre shoulder, and the inclination angles of the first folding line, the second folding line and the third folding line relative to the center line of the tread are gradually increased; a fourth folding line and a fifth folding line form the cross edge and the short edge of each h-shaped pattern main channel, and the fourth folding lines communicate the third folding lines with the fifth folding lines; the fourth folding lines and the fifth folding lines extend from the middle part of the tread to the tyre shoulder. Each folding line extends from the center of the tread to the tyre shoulder obliquely, the functions of guidance and drainage performances can be guaranteed, the inclination angle of each folding line relative to the center line of the tread is gradually increased, the edge ingredients of the pattern channels are improved by using the change of angles, and therefore the traction performance and the wetland holding performance are improved.

Description

technical field [0001] The invention relates to a pneumatic tire for a motorcycle, in particular to a tread pattern structure of a pneumatic tire for a scooter. Background technique [0002] In recent years, large scooters have become more and more popular among consumers. In order to ensure the guiding and drainage performance of pneumatic tires for large scooters, cooperation with figure 1 As shown, the tread pattern 1' is generally composed of streamlined inclined grooves. In order to improve the traction performance of the tire and improve its edge composition, the edge of the main groove 21' is designed with a concave-convex drop, but the main groove 21 is set in this way. 'There is a problem of different sizes of the ditch width, which reduces the drainage performance to a certain extent. In addition, in order to improve the wet grip performance when cornering, an inclined auxiliary groove 22' is added between the main grooves 21' to increase the contact area of ​​the...
