a tire

Abstract

The invention discloses a tire, comprising a tire tread, an outer secondary tap drain, a first cross ditch, an outer cross groove, a longitudinal groove, an inner secondary tap drain, a second cross ditch and an inner cross groove, wherein the tire tread is provided with an outer tap drain and an inner tap drain of the longitudinal groove structure; a cross groove forms an included angle together with the inner tap drain; the outer secondary tap drain is parallel to the outer tap drain; the first cross ditch forms an included angle together with the outer secondary tap drain; an auxiliary cross ditch is formed in one side of the outer secondary tap drain; the cross groove is an arc groove of which the width is gradually reduced; a distance is formed between the auxiliary cross ditch and the outer cross groove; a longitudinal groove communicated with the outer cross groove is arranged at one end of the outer cross groove; the inner secondary tap drain is parallel to the inner tap drain; the second cross ditch forms an included angle together with the inner tap drain; and the inner cross groove communicated with the inner secondary tap drain is an arc groove of which the width is gradually increased from the center of the tire to the edge. The outer pattern is complicated in structure, the road holding force of the tire is improved, the tire has good control when a vehicle turns, the anti-skidding performance is improved, the drainage property can be improved by the inner cross groove, a wetland water film is broken, the vehicle has good control and brake properties in the wetland, and the abrasion on the inner side of the tire is reduced, thus the service life of the tire is prolonged.

Description

technical field [0001] The present invention relates to the technical field of vehicle tires, and more specifically relates to a tire. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires, as the only medium for the vehicle to contact the ground, shoulder important responsibilities such as load bearing, braking and driving safety. When the vehicle is running on normal roads, the area where the tires really come into contact with the ground will never be much larger than the area where the soles of our shoes are in contact with the ground when we walk on the road. With such a small contact area, so many important and complex tasks need to be completed, and the pattern on the tire plays a vital role at this ...

AI Technical Summary

Problems solved by technology

Since the pattern is set as a symmetrical structure, the processing can be simplified. However, in practice, because the vehicle is turning, the force on the inner side and the outer side of the wheel is different, which will cause serious wear inside the tire and reduce the wear of the tire. service life
