Description

Technical Field

[0001] The present invention relates to a bulletproof tire structure and belongs to the technical field of safety tires. Background Art

[0002] Existing bulletproof tires basically have bulletproof supports or other supports such as bulletproof inner tubes arranged inside pneumatic tires. After the tire is shot and penetrated, or suddenly bursts during driving, or is punctured and leaks air, other supports such as bulletproof supports or bulletproof inner tubes inside the tire (hereinafter collectively referred to as supports) can replace the pneumatic tire to support the weight of the vehicle body, and ensure that the tire does not come off the rim, so as to achieve the purpose of enabling the vehicle to continue driving. In the actual use process of the existing inner supports of bulletproof tires, the situation of sliding left and right along the rim contact surface will occur, resulting in poor dynamic balance of the safety tire and reduced controllability during high-speed driving.

[0003] In order to ensure that the support does not slide left and right during use, the existing method is to use the method of increasing the pre-tightening force to tightly hoop the support on the rim. The alternating forces and alternating accelerations generated during the actual driving process of the vehicle, the vibration of the vehicle caused by the uneven road surface, and the thermal expansion and contraction caused by the change of the environmental temperature can all cause the material of the inner ring of the support to age due to the large sliding distance and frictional heating, the tightening force to decrease, and the support still slides left and right along the rim contact surface and cannot automatically return to the center of the rim. Therefore, there are still deficiencies in the existing technology and further improvement is needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a bulletproof tire structure, so that the support inside the bulletproof tire can automatically center and always be located on the center line of the rim, so as to improve the balance performance after the vehicle tire bursts, thereby overcoming the deficiencies of the existing technology.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A bulletproof tire structure of the present invention includes a tire; one or more centering positioning pins are arranged on both sides of the support inside the tire; the support contacts the inner edge of the bottom of the tire on the inner side of the rim through the centering positioning pins on both sides to keep the support always located at the center line position of the rim.

[0007] In the foregoing bulletproof tire structure, the centering positioning pin is a component made of an elastic flexible material or a compression deformation elastic component that can return to the initial state after the external force is released.

[0008] In the foregoing bulletproof tire structure, the centering positioning pin is in a columnar structure or a sheet structure; the columnar structure is a cylindrical shape or a polygonal columnar shape; the inside of the columnar structure or the sheet structure is a hollow structure or a solid structure.

[0009] In the aforementioned bulletproof tire structure, the support body is an annular structure formed by splicing one or more fan-shaped support units through bolts at the Z-shaped interface; the cross-section of the fan-shaped support unit is in the shape of an I-beam track, and one or more positioning holes are provided on both sides of the lower flange of the I-beam track, and centering positioning pins are installed in the positioning holes.

[0010] In the aforementioned bulletproof tire structure, the Z-shaped interface is formed by docking connection notches provided on different sides at both ends of the fan-shaped support unit; bolt holes are provided at the connection notches.

[0011] The above tire is an inflatable tire.

[0012] Due to the adoption of the above technical solution, compared with the prior art, the present invention adopts the technology of installing centering positioning pins on the side of the support body. The centering positioning pins installed on the side of the support body do not affect the assembly of the bulletproof tire. During the inflation use process, the centering positioning pins absorb the pressure and vibration generated during the left and right sliding of the support body, realizing the automatic centering of the support body on the left and right, and the support body is always located at the center of the rim. The present invention has the characteristics of simple structure, convenient installation, good dynamic balance performance, etc., and can be used for vehicles with bulletproof and air leakage prevention requirements, and the effect is better.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following further describes the present invention in detail with reference to the drawings and embodiments.

[0019] A bulletproof tire structure of the present invention, as shown in Figure 1 and Figure 2As shown in the figure, it includes a tire 1; the tire 1 is an inflated tire, and one or more centering positioning pins 3 are provided on both sides of the support body 2 inside the tire 1; the support body 2 contacts the inner edge 5 of the bottom of the tire on the inner side of the rim 4 through the centering positioning pins 3 on both sides to keep the support body 2 always located at the position of the rim center line 6. The centering positioning pins 3 are made of an elastic flexible material or a compression-deformed elastic component, and can return to the initial state after the external force is released. The centering positioning pins 3 are in a columnar structure or a sheet structure; the inside of the columnar structure or the sheet structure is a hollow structure or a solid structure; the cross-section of the columnar structure is circular or polygonal.

[0020] The support body 2 is composed of one or more Figure 4 shown fan-shaped support units 7 spliced together by bolts 9 at the Z-shaped interface 8 to form a Figure 3 shown annular structure; the cross-section of the fan-shaped support unit 7 is in the shape of an I-beam track, and one or more positioning holes 10 are provided on both sides of the lower flange of the I-beam track, and the centering positioning pins 3 are installed in the positioning holes 10; the Z-shaped interface 8 is formed by docking connection notches 11 provided on different sides at both ends of the fan-shaped support unit 7; bolt holes 12 are provided at the connection notches 11. Embodiment

[0021] As Figure 1 and Figure 2 shown, a support body 2 is provided inside the tire 1, and the support body 2 is a circular ring structure spliced by three fan-shaped support units 7 through bolts. Three positioning holes 10 are provided on both sides of the lower part of each fan-shaped support unit 7, and the centering positioning pins 3 are installed in each positioning hole 10. The centering positioning pins 3 are a compression-deformed structure and can return to the initial state after the external force is released. The inside of the centering positioning pins 3 can be a hollow structure or a solid structure; the centering positioning pins 3 can be a sheet structure or a columnar structure. The elastic coefficient of the centering positioning pins 3 is set according to the pressure required for installing the wheel rim. After the bulletproof tire is assembled, the centering positioning pins 3 return to the initial shape. After the tire is inflated and used, the centering positioning pins 3 can absorb the pressure and vibration generated during the left and right sliding of the support body 2, prevent the support body 2 from sliding left and right, and realize the automatic centering of the support body 2, always located on the rim center line 6. Bolt holes 12 are provided at both ends of the three fan-shaped support units 7, and the three fan-shaped support units 7 are fixed through bolts 9 passing through the bolt holes 12. This not only ensures the reliability of the installation but also facilitates disassembly.
