Tire with three-dimensional steel sheet pattern arranged on tread

Abstract

The invention discloses a tire with a three-dimensional steel sheet pattern arranged on a tread. The three-dimensional steel sheet pattern comprises a first pattern surface and a second pattern surface which are vertically and oppositely arranged and spaced by a pattern gap, and the first pattern surface and the second pattern surface are alternately provided with grooves and convex blocks in thehorizontal direction and the vertical direction; each convex block on any pattern surface has a groove corresponding to the convex block on the other pattern surface; each convex block comprises a round or oval convex block top face which is vertically arranged and a convex block inclined face which transits from the convex block top face to the pattern face where the convex block inclined face islocated; the intersection lines of the convex block inclined surface of one convex block and the pattern surface where the convex block is located form a first polygon; each groove comprises a circular or oval groove bottom face which is vertically arranged and a groove inclined face which is in transition from the groove bottom face to the pattern surface where the groove inclined face is located, and the intersecting lines of the groove inclined face of one groove and the pattern surface where the groove inclined face is located form a second polygon.

Description

technical field [0001] The invention relates to the field of tires, in particular to a tire with three-dimensional steel sheet patterns arranged on the tread. Background technique [0002] With the continuous development of technology in the global automobile industry, high-performance cars are gradually popularized. People's concept of cars is constantly improving, and the performance requirements for tires are also getting higher and higher. It is generally required that tires can match the driving of cars and provide Excellent handling performance and gripping performance, it can still provide good handling and gripping force on dry and wet roads or snow, so as to ensure good driving experience and safety. [0003] In winter tires or all-weather tires, the total length of the steel pattern in the tread pattern block is usually increased to improve the drainage performance of the tire pattern contact area and increase the contact area between the pattern and the road surfa...

AI Technical Summary

Problems solved by technology

[0005] Due to the small geometric size of the three-dimensional steel sheet pattern, the three-dimensional steel sheet in the prior art will have difficulties in demoulding during actual processing and production, damage to the pattern surface during demoulding, and wear of the steel sheet mold.
