AI Technical Summary
The design of existing tire pattern groove bottoms is poor in terms of anti-stone and anti-ditch capabilities, making it difficult to provide good grip and handling performance under complex road conditions.
A trench-resistant and anti-scratch stone tread structure is designed, using wavy groove bottom pattern grooves and asymmetric cross-sections, built-in rubber strips and positioning beads. The rubber strips are fixed in the tread through positioning beads, instead of being stabbed by stones at the bottom of the pattern groove bottom, and can be replaced to protect the tread.
It effectively reduces the possibility of stone clamping on the bottom of the pattern groove, improves the tire's anti-trough performance and service life, and improves the grip and handling performance under complex road conditions.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tread structures, in particular to a tread structure that resists groove cracking and stone clamping. Background Art
[0002] The bottom of the tire pattern groove refers to the bottom part of the groove in the tire pattern. These grooves are designed in different shapes and depths to provide good traction and drainage performance. The main function of the tire pattern groove bottom is to increase the contact area between the tire and the road, and provide better grip and handling performance. In addition, the pattern groove bottom can also help drain water, prevent water from accumulating between the tire and the road, and improve the safety of wetland driving. For example, the invention patent with the announcement number CN111619291A discloses a design method for a load-bearing tire, and in particular, it relates to a design method for a durable groove bottom pattern of a load-bearing tire and its application. The design method of the durable groove bottom pattern of a load-bearing tire, the tire pattern groove adopts a rounded design, and the risk of groove bottom cracking is small. The design of the existing tire pattern groove bottom is a linear design, and the groove bottom is mostly symmetrical, which is suitable for driving on very good road conditions such as long-distance / high-speed, and its straight-line driving performance is good, but the anti-stone clamping and groove cracking capabilities of this pattern are relatively poor. Therefore, it needs to be improved. Utility Model Content
[0003] The utility model aims to provide a groove crack and stone clamping resistance tread structure, which solves the problem that the stone clamping and groove crack resistance capabilities of this type of pattern are relatively poor.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-groove crack and anti-stone pinching tread structure, comprising a tire, the tread of the tire is provided with a groove bottom pattern groove, a rubber strip is placed on the inner side of the groove bottom pattern groove, and a positioning bead is fixedly connected to the bottom of the rubber strip, and the positioning bead is clamped with the tread of the tire.
[0005] Preferably, the groove bottom pattern is wavy and has an asymmetric cross section. The wavy groove bottom pattern design ensures the performance of anti-stone clamping and groove cracking.
[0006] Preferably, the tire tread is provided with a positioning card slot, and the positioning card bead is located in the positioning card slot, and the positioning card slot is communicated with the groove bottom pattern groove. The positioning card slot is provided to facilitate the accommodation of the positioning card bead in the tire tread.
[0007] Preferably, the rubber strip is wavy and made of rubber. The rubber strip can replace the tire tread that is punctured by stones and can be replaced later.
[0008] Preferably, there are multiple positioning beads, and the positioning beads and the rubber strip are an integrated structure. The positioning beads are arranged to facilitate the fixing of the rubber strip in the groove bottom pattern.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] 1. The utility model can effectively reduce the possibility of stone clamping at the bottom of the tread pattern of the tire by designing the tread pattern of the tire into a wavy groove bottom and designing the cross section of the groove bottom into an asymmetric form.
[0011] 2. The utility model accommodates a rubber strip with the same wave path as the groove bottom in the newly designed groove bottom, and the rubber strip is fixed in the groove bottom by the positioning beads at the bottom thereof. In this way, the rubber strip can replace the bottom of the groove bottom that is pierced by stones, and at the same time, the replaceability of the rubber strip is used to protect the tread, thereby increasing the service life of the tire.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-5A tread structure for resisting groove cracking and stone pinching includes a tire 1. The tread of the tire 1 is provided with groove bottom pattern grooves 2. The groove bottom pattern grooves 2 are wavy and have an asymmetric cross-section. The wavy design of the groove bottom pattern grooves 2 ensures the performance of resisting stone pinching and groove cracking. A rubber strip 3 is placed on the inner side of the groove bottom pattern grooves 2. A positioning bead 4 is fixedly connected to the bottom of the rubber strip 3. The positioning bead 4 is clamped with the tread of the tire 1. The tread of the tire 1 is provided with a positioning card groove 5. The positioning card groove 5 is located in the positioning card groove 5. The positioning card groove 5 is in communication with the groove bottom pattern groove 2. The provision of the positioning card groove 5 facilitates the placement of the positioning card bead 4 in the tread of the tire 1.
