Description

Tire with a tire cover Technical Field The utility model relates to the technical field of tire production, in particular to a tire. Background Tires are ground-engaging rolling, annular elastomeric rubber articles assembled on a variety of vehicles or machines. The automobile body is usually arranged on a metal rim, can support the automobile body, buffer external impact, realize contact with a road surface and ensure the running performance of the automobile. Tires are often used under complex and severe conditions, and they are subjected to various deformations, loads, forces and high and low temperatures during running, and therefore must have high load-bearing, traction and cushioning properties, and at the same time, high wear and flex resistance, as well as low rolling resistance and heat generation. In order to facilitate the drainage of the tire, most of the existing tires are provided with longitudinal grooves, the rigidity of the tread of the tire is damaged due to overlarge angles of the longitudinal grooves, rolling resistance is adversely affected, and the damage to the tire is easily caused by stone clamping due to overlarge angles of the grooves. The information disclosed in this background section is only for enhancement of understanding of the general background of the utility model and should not be taken as an acknowledgement or any form of suggestion that this information has been made as prior art that is well known to a person of ordinary skill in the art. Disclosure of utility model The utility model aims to solve the technical problem that the tire is easy to clamp stone on the basis of ensuring the rigidity of the tire. The utility model solves the technical problems by the following technical means: The utility model claims a tire, the tire tread is provided with at least two grooves along the circumferential direction, the tire treads at two sides of the grooves form pattern blocks, the grooves are uniformly distributed along the width direction of the tire, each groove comprises a first notch section, a transition section and a second notch section, the grooves are distributed with the first notch section and the second notch section at intervals along the length direction of the groove, the sizes of the ravines of the first notch section and the second notch section are different, and the first notch section and the second notch section are connected through the transition section to form wavy grooves. Through the different sizes of the ravines of the first notch section and the second notch section, the rigidity of the tire is ensured, and when the groove is used for clamping stones, the stones can be rapidly discharged along the transition section to protect the groove bottom. Preferably, the longitudinal cross-section of the first slot segment is of V-groove cross-sectional configuration. The gully of first notch section is comparatively mild to the gully of second notch section narrow degree, even the clamp stone gets into, also can discharge fast smoothly. Preferably, the longitudinal section of the second notch section comprises a bevel part and a notch part, the tread of the tire is provided with a trapezoid groove, the inner side wall of the trapezoid groove forms the bevel part, and the bottom of the trapezoid groove is provided with a U-shaped groove to form the notch part. The inclined surface part is more severe than the V-shaped groove, and the U-shaped groove opening is smaller, so that the rigidity of the tire can be well ensured even if the tire tread is provided with a groove. Preferably, the second included angle formed by the trapezoid groove surface and the vertical line passing through the V-shaped groove opening is beta, wherein beta is more than or equal to 1 degree and less than or equal to 30 degrees. Preferably, the bottom of the V-shaped groove is provided with an arc chamfer. The arc chamfer can play a good buffering role on the trapezoid groove surface, and the problem of stone clamping caused by excessive narrowing is avoided. Preferably, the first included angle formed by the V-shaped groove surface and the vertical line passing through the V-shaped groove opening is alpha, wherein alpha is more than or equal to 1 degree and less than or equal to 30 degrees. The second contained angle and the first contained angle are arranged, so that the rigidity of the tire can be guaranteed while the smooth drainage of the groove is guaranteed. Preferably, the inner wall of the transition section is an arc surface, and the inner wall of the first notch section and the inner wall of the second notch section are smoothly transited by the arc surface along the length direction to form a wavy groove. In the continuous transition change of the transition section, the groove surface is periodically contracted and expanded, and finally the wavy groove is formed. Preferably, the surfaces of the pattern blocks are provided with steel sheets along the circumferential di
