Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to an anti-stone pinching tire structure. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

[0003] During the tire production process, grooves are opened on the tires. Since there are gaps between adjacent tread blocks, when the tire rolls on the road, hard objects such as stones on the road surface will be sandwiched between the tread blocks through the gaps. After the tire continues to roll for a period of time with the stones sandwiched between them, the stones will scratch the tire, resulting in a shorter service life of the tire. Therefore, an anti-stone sandwich tire structure is proposed. Utility Model Content

[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] Reference Figure 1-4A stone-crushing-proof tire structure comprises a tire body 1, a tire pattern groove 1 2 is provided on the surface of the tire body 1, a tire pattern groove 2 3 is provided inside the tire pattern groove 1 2, a tire pattern groove 3 4 is provided inside the tire pattern groove 2 3, a gravel pushing ring 5 is fixedly provided on the lower side wall of the tire pattern groove 3 4, the number of the tire pattern groove 1 2, the tire pattern groove 2 3 and the tire pattern groove 3 4 is several, and the several tire pattern grooves 1 2, the several tire pattern grooves 2 3 and the several tire pattern grooves 3 4 are all distributed in a linear array, the longitudinal cross-section of the tire pattern groove 1 2, the longitudinal cross-section of the tire pattern groove 2 3 and the longitudinal cross-section of the tire pattern groove 3 4 are all in an inverted trapezoidal shape, and the tire The longitudinal cross-sectional areas of the tread groove 1 2, the longitudinal cross-sectional areas of the tread groove 2 3 and the longitudinal cross-sectional areas of the tread groove 3 4 decrease from top to bottom in sequence. The tread groove 1 2, the tread groove 2 3 and the tread groove 3 4 have inverted trapezoidal longitudinal cross-sections, so that the inner walls of the tread groove 1 2, the tread groove 2 3 and the tread groove 3 4 are inclined, so that the cross-sectional areas of the gravel and the tread groove 1 2, the tread groove 2 3 and the tread groove 3 4 are reduced, thereby making it easier for the gravel to be pushed by the gravel pushing ring 5. The longitudinal cross-sectional area of ​​the gravel pushing ring 5 is triangular, and the gravel pushing ring 5 is made of rubber material. The interior of the gravel pushing ring 5 is elastic. Through the setting of the gravel pushing ring 5 , the gravel entering into the tire tread groove 1 2, the tire tread groove 2 3 and the tire tread groove 3 4 can be quickly pushed out, so that the gravel will not be stuck in the tire body 1. The surface of the gravel pushing ring 5 is penetrated with sand and gravel blowing holes 6. There are a plurality of sand and gravel blowing holes 6. The plurality of sand and gravel blowing holes 6 are penetrated and arranged on the surface of the gravel pushing ring 5 and are distributed in a circular array. Through the arrangement of the sand and gravel blowing holes 6, when the gravel pushing ring 5 is squeezed, the air inside it is blown out, so that the gravel is blown out of the tire body 1, avoiding excessive gravel adhering to the tire body 1. The gravel pushing ring 5 is composed of two semicircular rings, and the two semicircular rings are bonded together. The ring 5 is convenient for being installed inside the tire pattern groove three 4, making the installation of the gravel pushing ring 5 more convenient and quick. The tire pattern groove one 2, the tire pattern groove two 3 and the tire pattern groove three 4 are arranged in a stepped manner to avoid the deformation of the tire pattern groove two 3 and the tire pattern groove three 4 due to the entry of large gravel, causing the gravel to be stuck in the tire body 1. Secondly, the elastic gravel pushing ring 5 is arranged so that after the gravel pushing ring 5 is squeezed and deformed by the gravel, the gravel can be pushed out from the tire pattern groove one 2, the tire pattern groove two 3 and the tire pattern groove three 4 by the rebound thrust, thereby avoiding the gravel being stuck in the tire body 1, so that the tire body 1 has the function of preventing stone clamping.

[0020] In use: after the tire body 1 is installed on the vehicle, during the driving process of the vehicle, gravels enter the tire tread groove 1 2, wherein small gravels cannot get stuck in the tire tread groove 1 2, tire tread groove 2 3 and tire tread groove 3 4, and thus will be thrown out, while large gravels first enter the tire tread groove 1 2, and because during the driving process, the road surface will push the gravels to squeeze the gravel pushing ring 5, causing the gravel pushing ring 5 to deform. When the tire body 1 moves to a position where it is not in contact with the road surface, the gravel pushing ring 5 will rebound and push the gravel out of the tire tread groove 1 2, the tire tread groove 2 3 and the tire tread groove 3 4. When the gravel squeezes the gravel pushing ring 5, the air in the gravel pushing ring 5 is discharged through the gravel blowing hole 6, so that the air blows the gravel out of the tire.

[0021] To summarize, the anti-stone pinching tire structure avoids the deformation of tire pattern groove 2 3 and tire pattern groove 3 4 due to the entry of large gravel, causing the gravel to be stuck in the tire body 1, by arranging the tire pattern groove 1 2, tire pattern groove 2 3 and tire pattern groove 3 4 in a stepped manner. Secondly, by arranging the elastic gravel pushing ring 5, the gravel pushing ring 5 is squeezed and deformed by the gravel, and the gravel can be pushed out of the tire pattern groove 1 2, tire pattern groove 2 3 and tire pattern groove 3 4 by the rebound thrust, thereby avoiding the gravel from being stuck in the tire body 1, so that the tire body 1 has an anti-stone pinching function, which is used to solve the problems raised in the above-mentioned background technology.
