Tread pattern structure of pneumatic tires for two-wheelers

Abstract

The invention discloses a tread pattern structure of pneumatic tires for two-wheelers. Each tire tread consists of a plurality of tread pattern units arranged alternately and symmetrically along the circumferential direction of the corresponding pneumatic tire, wherein each of the tread pattern units comprises a primary angle groove and a subsidiary angle groove; each primary angle groove extends from a tire equatorial plane towards a tire shoulder, and is formed by connecting a wide primary angle groove of which the opening faces the inside of the axial direction with a narrow primary tread of which the opening faces the outside of the axial direction; and each subsidiary angle groove is arranged between the two corresponding primary angle grooves of two tread pattern units adjacent to each other at the same side of the tire equatorial plane, and is formed by connecting a wide subsidiary angle groove of which the opening faces the outside of the axial direction with a narrow subsidiary tread of which the opening faces the inside of the axial direction. The openings of each primary angle groove and the corresponding subsidiary angle groove at the same side are alternately arranged in the opposite direction, so as to ensure good abrasion resistance performance and drainage performance of the tire tread and improve the traction performance of the tire tread of the pneumatic tires at the same time.

Description

technical field [0001] The invention relates to a tread pattern structure of a pneumatic tire, in particular to a tread pattern structure of a pneumatic tire for two-wheeled vehicles. Background technique [0002] With the continuous development of two-wheeled vehicles, the displacement of vehicles is also increasing, requiring vehicles to be used in various road conditions, including asphalt roads, cement roads and combined urban and rural roads. More and more, the demand for its tires can also exert excellent performance in various road conditions. In the past, if two-wheeled vehicles were used on asphalt roads and concrete roads, their tire treads were often designed with inclined transverse groove patterns (such as figure 1 shown), which can ensure drainage performance and wear performance, but when used on urban and rural roads, the tread pattern of the tire is relatively large, the edge composition of the groove is low, and the traction performance is poor. If the ti...

Problems solved by technology

In the past, if two-wheeled vehicles were used on asphalt roads and cement roads, the treads of their tires were often designed with inclined transverse groove patterns (such as Figure 1), can ensure drainage performance and wear performance, but when used on urban and rural roads, the tread pattern of the tire is relatively large, and the edge composition of the groove is low , poor traction performance

If the tires are used on both urban and rural roads, the tire tread often adopts a vertical and horizontal mixed block pattern design (such as Figure 2), it can increase the edge composition of the pattern and improve the traction performance, but the land ratio of the pattern is low, and its wear performance is not good
