Embodiment Construction

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the detailed description is as follows in conjunction with the accompanying drawings: the tread structure of an all-weather tire includes a carcass 1, and an annular longitudinal main groove is arranged at the center of the carcass 1 Groove 3; the width of the top of the longitudinal main groove 3 is 4mm-6mm, the inclination angle range between the side wall of the groove section of the longitudinal main groove 3 and the vertical direction is 5°-12°, and the bottom of the longitudinal main groove 3 is inverted The angular range is R0.5mm-R2mm; the shape of the longitudinal main groove 3 presents a "U-shaped" shape, which accelerates the drainage performance of the tire. Both sides of the longitudinal main groove 3 are evenly provided with transverse main grooves 11 along the rolling direction of the tire, and the transverse main grooves 11 ...

Abstract

The invention discloses an all-weather tire tread structure, which comprises a tire body, wherein an annular longitudinal main groove is formed in a center of the tire body; transverse main grooves are uniformly formed on two sides of the longitudinal main groove in a rolling direction of a tire and the transverse main grooves corresponding to each other in a horizontal position at the two sides of the longitudinal main groove are of an upside-down V-shaped structure; single-guide transverse pattern blocks are arranged between the longitudinal transverse main grooves; straight steel sheet finegrooves, single-bending steel sheet fine grooves and double-bending steel sheet fine grooves are formed in sequence at one end close to the longitudinal main groove of each single-guide transverse pattern block; and crossed straight steel sheets are arranged in the middle of the double-bending steel sheet fine grooves. Compared with the prior art, the all-weather tire tread structure has the advantages that the defect of single tire performance in the prior art is overcome, dry land grabbing performance and wet land grabbing performance are met, snow land performance in winter is achieved, and low noise and low rolling resistance functions are achieved.

Description

technical field [0001] The invention relates to the field of tires, in particular to an all-weather tire tread structure. Background technique [0002] With the popularization of modern urban vehicles, people have higher and higher requirements for tires. Snow tires are used in winter, and summer tires are replaced in summer. Frequent tire replacement brings a lot of waste of time and energy to people. In order to meet the market demand, all-season tires that can adapt to different weathers and climate changes throughout the year are needed. They must not only meet the dry grip performance, wet grip performance, good noise performance, but also meet the snow performance. [0003] At present, in some foreign regions such as Canada, it snows for a long time in a year, and the government departments require that all tires be replaced with all-weather tires in order to increase the safety factor. It also accelerated the development of all-season tires. Contents of the inventi...
