Description

Technical Field

[0001] The utility model relates to the technical field of engineering tires, in particular to an engineering tire reinforcement structure. Background Art

[0002] Engineering tires refer to tires with good wear resistance and low heat generation. They are usually composed of four parts: cord layer, bead, buffer layer and tread.

[0003] The buffer layer is also called the belt layer, support layer, hard buffer layer, etc. The belt layer is relatively thin, which leads to a smaller contact area between the edge of the belt layer and the tread, resulting in a higher pressure at the contact point. Since the hardness of the belt layer is greater than that of the tread, and due to the difference in physical properties between the belt layer and the tread, the degree and speed of deformation are different. Therefore, when the engineering tire undergoes elastic deformation, there is a slight difference in the degree of strain between the belt layer and the tread. For example, when the left side of the tire is subjected to force, the rubber material of the tire itself deforms first and transmits the external force to the belt layer. At this time, there is an interaction force between the belt layer and the tire. Since the contact area here is small, the pressure is large. The large pressure will damage the contact between the tire and the belt layer. Long-term extrusion will cause the damage to accumulate, and then cause cracks to appear inside the tread. Therefore, an engineering tire reinforcement structure is proposed to solve the above-mentioned problems. Utility Model Content

[0004] Based on the above description, the utility model provides an engineering tire reinforcement structure to solve the problem that the pressure between the belt layer and the tread is relatively large, resulting in damage to the inside of the tread.

[0005] The utility model provides a technical solution to the above technical problems as follows: an engineering tire reinforcement structure, comprising: a carcass, and a belt layer, a cord layer and a bead wire are all arranged inside the carcass, a side ring structure is arranged inside the carcass, and is respectively arranged on both sides of the belt layer, and comprises a mounting block, a connecting block and a movable connecting rod, a receiving groove is arranged on the surface of the connecting block, the belt layer extends to the inside of the receiving groove, and the movable connecting rod is movably connected to the mounting block and the connecting block at the same time.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the mounting blocks, the connecting blocks and the movable connecting rods are all distributed in an annular manner and at equal distances along the outer ring of the carcass.

[0008] Furthermore, the mounting block and the connecting block are mutually formed into a cylindrical block, and the cylindrical block and the movable connecting rod are cross-distributed.

[0009] Furthermore, the mounting block includes a first block body, a positioning blind hole is provided on one side of the first block body close to the connecting block, and first movable grooves are provided at both ends of the first block body.

[0010] Furthermore, the first block is a semi-cylindrical block, and the first movable groove is a hemispherical groove.

[0011] Furthermore, the connecting block includes a second block body, and a positioning column is provided on a side of the second block body close to the mounting block, and the positioning column extends to the inside of the positioning blind hole.

[0012] Furthermore, a receiving groove is provided on a side of the second block close to the belt layer, and second movable grooves are provided at both ends of the positioning column, and the second movable grooves are hemispherical grooves.

[0013] Furthermore, the movable connecting rod includes a rod body, and spherical blocks are arranged at both ends of the rod body. The spherical blocks are arranged inside the second movable groove and the first movable groove.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] 1. The utility model provides a side ring structure and other components, and the side ring structure cooperates with the belt layer, so that when the belt layer is deformed, the force acts on the connecting block. The cylindrical body composed of the mounting block and the connecting block has an arc surface. Therefore, when the cylindrical block is squeezed by the belt layer to squeeze the carcass, the interaction force between the cylindrical block and the carcass can be dispersed to the surface of the cylindrical block;

[0016] 2. By setting the mounting block, the connecting block and the movable connecting rod, the effect of the angle between the cylindrical block and the movable connecting rod can be changed, so that the side ring structure can deform normally along with the carcass when the tire is in use, so that the side ring structure weakens the influence of the belt layer on the carcass without affecting the normal use of the tire.

[0029] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0031] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0032] See also Figure 1 , an engineering tire reinforcement structure, comprising:

[0033] a carcass 1; and

[0034] The belt layer 2, the carcass layer 3 and the bead wire 4 are all arranged inside the carcass 1;

[0035] Based on the above, the carcass 1, belt layer 2, cord layer 3 and bead wire 4 are all prior art, and their specific positional relationship in the tire is also prior art. These existing structures are cited here only to facilitate the understanding of the positional relationship of the side ring structure 5. Therefore, the specific structures of the belt layer 2, cord layer 3 and bead wire 4 are not repeated here.

[0036] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, the side ring structure 5 is arranged inside the carcass 1 and respectively arranged on both sides of the belt layer 2, and includes a mounting block 51, a connecting block 52 and a movable connecting rod 53, the mounting block 51, the connecting block 52 and the movable connecting rod 53 are all distributed in an annular shape and equidistantly along the outer ring of the carcass 1, the mounting block 51 and the connecting block 52 form a cylindrical block, and the cylindrical block and the movable connecting rod 53 are cross-distributed;

[0037] Based on the above, the internal structure of the side ring mechanism 5 forms a complete annular block, which can be subjected to the force of the belt layer 2, and the mounting block 51 and the connecting block 52 form a cylindrical block, and the contact between the cylindrical block and the inside of the tire body 1 is an arc surface. Therefore, when there is an interaction force between the tire body 1 and the cylindrical block, the force can be dispersed to the entire surface of the cylindrical block, thereby dispersing the force and avoiding the occurrence of excessive pressure.

[0038] like Figure 7-Figure 9 As shown, the mounting block 51 includes a first block 511, a positioning blind hole 513 is provided on one side of the first block 511 close to the connecting block 52, first movable grooves 512 are provided at both ends of the first block 511, the first block 511 is a semi-cylindrical block, and the first movable groove 512 is a hemispherical groove;

[0039] The connecting block 52 has a receiving groove 524 on its surface, and the belt layer 2 extends to the inside of the receiving groove 524. The connecting block 52 includes a second block 521, and a positioning column 522 is provided on the side of the second block 521 close to the mounting block 51. The positioning column 522 extends to the inside of the positioning blind hole 513. The second block 521 has a receiving groove 524 on the side close to the belt layer 2, and both ends of the positioning column 522 are provided with second movable grooves 523, and the second movable grooves 523 are hemispherical grooves.

[0040] Based on the above, the connecting block 52 and the mounting block 51 cooperate with each other to form a cylindrical block. At this time, the positioning blind hole 513 and the positioning column 522 cooperate with each other to play a positioning role, thereby avoiding misalignment between the connecting block 52 and the mounting block 51. The first movable groove 512 and the second movable groove 523 cooperate with each other to restrict the spherical block 531, so that the spherical block 531 can only rotate around its center of circle. The setting of the receiving groove 524 plays a role of contacting the belt layer 2, thereby avoiding the situation where the force of the belt layer 2 directly acts on the tire body 1.

[0041] like Figure 5 and Fig.10 As shown, the movable connecting rod 53 includes a rod body 532, and spherical blocks 531 are arranged at both ends of the rod body 532. The spherical blocks 531 are arranged inside the second movable groove 523 and the first movable groove 512;

[0042] Based on the above, the movable link 53 cooperates with the cylindrical block composed of the connecting block 52 and the mounting block 51, so that the angles of the movable link 53 and the cylindrical block can change after being subjected to force, thereby enabling the side ring structure to undergo elastic deformation along with the tire, and the side ring structure itself does not have elastic force after deformation, and can only move and recover along with the tire body 1, so it will not have a negative impact on the interior of the tire body 1.

[0043] In actual use, this embodiment is implemented by placing both sides of the belt layer 2 inside the storage groove 524, and placing the movable connecting rod 53 inside the first movable groove 512 and the second movable groove 523;

[0044] When the engineering tire is elastically deformed by external force, the belt layer 2 is deformed together and squeezes the connecting block 52, so that the side ring structure 5 and the inside of the carcass 1 are squeezed against each other. Firstly, the surface area of ​​the side ring structure 5 is larger than the surface area of ​​the side of the belt layer 2. Under the same force, the pressure between the side ring structure 5 and the carcass 1 is smaller, so as to reduce the negative impact of the interaction force on the inside of the carcass 1. Secondly, the surface of the cylinder composed of the mounting block 51 and the connecting block 52 is a circular surface. Therefore, when the cylindrical block is squeezed against the carcass 1 by force, the interaction force will be dispersed to the entire circular surface, so as to achieve the effect of dispersing pressure and further reduce the negative impact on the carcass 1.

[0045] The reinforcement structure of the engineering tire is provided with a side ring structure, so that the compression of the belt layer 2 on the inside of the carcass 1 is weakened, thereby avoiding the situation where the inside of the carcass 1 is damaged or even broken due to the high pressure during the compression process.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
