Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Such as Figure 2 to Figure 3 As shown, the present invention discloses a tire tread pattern structure. The tread 0 is cut from several inclined pattern groove groups, and each pattern groove group is arranged symmetrically and staggered relative to the center line of the tread. The tire tread is divided into a central contact area and two shoulder areas. The axial width Cr of the central contact area is set to 1 / 3 of the total tread width TW, and the axial width S of the shoulder areas on both sides is the total tread width TW. 1 / 3 of. Each groove group includes main grooves 20 and auxiliary grooves, and the auxil...

Abstract

The invention discloses a pattern structure of a tire tread and relates to the field of tires. The tire tread is formed by cutting a plurality of oblique pattern groove groups, and the pattern groovegroups are symmetrically staggered relative to the center line of the tire tread; each pattern groove group comprises a main pattern groove and an auxiliary pattern groove, and each auxiliary patterngroove is composed of a first auxiliary pattern groove and a second auxiliary pattern groove; and each main pattern groove obliquely extends upward to a tire shoulder from the position close to the center line of the tire tread, each first auxiliary pattern groove obliquely extends upward to the tire shoulder from the edge of a center grounding area, and each second auxiliary pattern groove is formed in the tire shoulder and is close to the middle section of each main pattern groove. The pattern structure of the tire tread, provided by the invention, can ensure drainage performance and traction performance, can enhance the rigidity of patterns in tire shoulder areas to improve the turning performance, and can effectively break a water film to improve the ground gripping performance duringturning.

Description

technical field [0001] Embodiments of the present invention relate to tires, and more particularly, embodiments of the present invention relate to a tire tread structure. Background technique [0002] In recent years, the models of electric motorcycles on the market are constantly changing, and the appearance, style and performance of the vehicles are also constantly changing. Now, the speed of vehicles is getting faster and faster, and the requirements for vehicle handling, tire grip and cornering stability are increasing. In order to reduce power consumption and extend the cruising range of electric motorcycles, it is necessary to reduce tire rolling resistance. Generally, tread grooves are reduced to ensure a continuous ground contact surface. Tires are generally designed with streamlined inclined grooves. However, the smooth tread will reduce the drainage performance and grip when driving on wet ground, affect the braking performance, and lead to potential safety hazar...
