Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a groove crack and stone clamping resistant tire pattern. Background Art

[0002] Compared with developed countries such as Europe and the United States, domestic commercial vehicle tires now mostly use striped patterns for tractor / truck models. Striped patterns are mostly suitable for use on high-speed and good road conditions. The existing striped pattern tire groove design generally adopts a straight groove bottom (or an additional stone platform), a stepped groove or a variable angle groove design.

[0003] However, the usage conditions in various regions of the country are different, and the existing design scheme cannot effectively prevent stones from damaging the groove bottom. Stones can easily damage the groove bottom, and in serious cases, they may touch the steel wire. Water, mud, and other substances may penetrate from the damaged position, causing the tire to delaminate and burst. Therefore, a groove-resistant and stone-clip-resistant tire pattern is needed to meet people's needs. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a groove-resistant and stone-crack-resistant tire pattern, comprising a tire, wherein the tire is provided with a groove and a stone-removing block, the stone-removing block is located at the lower end of the tire top pattern, the top of the stone-removing block is inclined, the groove is located on one side of the stone-removing block, and is connected to the downwardly inclined end of the stone-removing block, the two side walls of the groove respectively form a certain angle with the tire radial direction, and the opening width is greater than the bottom width.

[0006] Preferably, the angles between the sidewall of the groove connected to the stone removal block and the other sidewall and the tire radial direction are both 0° to 45°.

[0007] Preferably, the height between the connection between the stone removal block and the side wall of the groove and the top pattern is 0 to 10 mm.

[0008] Preferably, the height of the stone-removing block is between 0 and half of the overall depth of the tread groove.

[0009] Preferably, the depth from the connection between the pattern groove and the stone removal block to the bottom of the pattern groove is 0 to half of the overall depth of the pattern groove.

[0010] Preferably, the width of the stone removal block is 0 to the opening width of the groove.

[0011] Preferably, the length of the stone removal block is 0-50 mm.

[0012] The beneficial effects of the utility model are:

[0013] The utility model adopts a variable angle design for the tread grooves and adds a stone removal block design to the sidewalls of the tread grooves, thereby helping to prevent the tread from being cut and damaged by stones, thereby increasing the service life of the tire, preventing tire blowouts, and improving the driving safety of the driver.
