Description

Technical Field

[0001] This utility model belongs to the field of tire technology, and in particular relates to a wear-resistant tire. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, support the vehicle body, buffer external impacts, make contact with the road surface, and ensure the vehicle's driving performance.

[0003] Currently, tires on the market are not only suitable for cars, but also for non-motorized vehicles, such as electric bicycles. Existing tires for non-motorized vehicles are divided into pneumatic tires and solid tires. However, the internal structure of existing solid tires for non-motorized vehicles is mostly integrated. Therefore, when the internal structure of the tire is damaged, the entire tire needs to be replaced. In other words, it is difficult to repair or salvage the tire, resulting in low overall practicality. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a wear-resistant tire that can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a wear-resistant tire, including a hub, and further comprising: a tire body fitted on the outer side of the hub; a protrusion fixed on the outer arc surface of the hub; a through hole on the inner side of the hub; a groove on the upper surface of the protrusion; inner support steel plates distributed on the inner side of the tire body; a support seat fixed at the bottom of the inner support steel plates; a snap-fit ​​seat fixed on the side of the support seat away from the inner support steel plates; a positioning bolt passing through the inner side of the through hole; a pad provided on the inner sidewall of the hub; and a noise-absorbing structure provided on the inner side of the tire body.

[0007] Furthermore, the noise reduction structure includes a sound-absorbing cotton pad and an arc-shaped groove. The sound-absorbing cotton pad is disposed on the inner sidewall of the tire body, and the inner arc surface of the sound-absorbing cotton pad is provided with an arc-shaped groove.

[0008] Furthermore, the outer arc surface of the tire body is provided with anti-slip grooves, and the surface of the tire body is provided with anti-slip rubber strips.

[0009] Furthermore, the protrusions are equidistantly distributed along the center point of the hub, and the protrusions and the hub form an integrated structure.

[0010] Furthermore, the inner support steel plates are equidistantly distributed along the center point of the wheel hub, and the side of the inner support steel plate away from the support seat is an arc-shaped surface.

[0011] Furthermore, the inner side of the snap-fit ​​seat is provided with a threaded groove whose diameter is adapted to the outer diameter of the positioning bolt, and the snap-fit ​​seat is equidistantly distributed along the center point of the hub.

[0012] This utility model has the following beneficial effects:

[0013] This utility model, by setting up structures such as inner support steel plates, support seats and positioning bolts, can facilitate the subsequent disassembly and replacement of the internal structure of the tire. Compared with the existing integrated solid tires, it has greater flexibility and realizes the split design of the internal structure of the tire. When some inner support steel plates or support seats are damaged, only some structures need to be replaced, reducing resource consumption and making the overall practicality higher.

[0014] This invention, through the design of sound-absorbing cotton pads and arc-shaped grooves, can easily achieve the purpose of noise reduction, reducing tire noise generated during operation. Multiple arc-shaped grooves evenly distributed along the inner wall of the sound-absorbing cotton pad make the inner wall of the cotton pad wavy. When sound waves are incident, the structure of the crests and troughs on the inner wall of the wavy sound-absorbing cotton pad causes the sound waves to undergo multiple reflections, scattering, and diffractions. This complex path extends the propagation distance of the sound waves inside the material, increases the chance of energy loss, and thus achieves the purpose of sound absorption.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-5 As shown, this utility model is a wear-resistant tire, including a hub 1, and further including: a tire body 2 sleeved on the outer side of the hub 1, a protrusion 3 fixed on the outer arc surface of the hub 1, a through hole 4 opened on the inner side of the hub 1, a groove 5 opened on the upper surface of the protrusion 3, inner support steel plates 6 distributed on the inner side of the tire body 2, and a support seat 7 fixed on the bottom of the inner support steel plate 6, the outer side of the inner support steel plate 6 is an arc surface, and multiple inner support steel plates 6 are combined to form a ring, the support seat 7 is made of steel, a snap-fit ​​seat 8 is fixed on the side of the support seat 7 away from the inner support steel plate 6, a bolt groove with a diameter size adapted to the positioning bolt 9 is opened at the bottom of the snap-fit ​​seat 8, the positioning bolt 9 passes through the inner side of the through hole 4, a pad 10 is provided on the inner side wall of the hub 1, and a sound-absorbing structure is provided on the inner side of the tire body 2;

[0025] During operation, firstly, one end of the snap-fit ​​seat 8 at the bottom of the support base 7 is inserted into the groove 5 on the upper surface of the protrusion 3. The fit between the two achieves an initial connection between the support base 7 and the wheel hub 1. When the snap-fit ​​seat 8 and the protrusion 3 are fully engaged, the pad 10 is placed against the inner wall of the wheel hub 1. Then, the positioning bolt 9 is passed through the hole on the surface of the pad 10. The positioning bolt 9 then passes through the inner side of the through hole 4 and extends into the bolt groove at the bottom of the snap-fit ​​seat 8, whose diameter matches the bolt. Rotating the positioning bolt 9 then positions the snap-fit ​​seat 8, thus achieving a stable connection between the inner support plate 6 and the wheel hub 1. Similarly, multiple sets of inner support plates 6... The inner support plates 6 are installed on the outer surface of the wheel hub 1. After the inner support plates 6 are installed, since the outer side of the inner support plates 6 is curved, the multiple sets of inner support plates 6 form a ring. Then, the tire body 2 is fitted onto the outside of the ring, and the outer curved surface of the inner support plates 6 contacts the inner curved surface of the tire body 2. Thus, the multiple inner support plates 6 and the support seat 7 can be used to support the entire tire. Moreover, the easy-to-disassemble structure makes it convenient to replace the inner support plates 6 later. The splicing of multiple inner support plates 6 makes the internal structure of the tire a split design, which makes the overall practicality higher. After the multiple inner support plates 6 are installed, the tire body 2 can be installed on the wheel hub 1.

[0026] The noise reduction structure includes a sound insulation pad 11 and an arc groove 12. The sound insulation pad 11 is disposed on the inner side wall of the tire body 2, and the inner arc surface of the sound insulation pad 11 is provided with an arc groove 12.

[0027] When the tire generates significant noise during operation, the noise is transmitted through the sound-insulating pad 11 on the inner side of the tire body 2. The sound-insulating pad 11 serves to insulate the tire. Furthermore, the multiple arc-shaped grooves 12 on the inner wall of the sound-insulating pad 11 create a wavy appearance. When sound waves are incident, the wave crests and troughs on the inner wall of the wavy sound-insulating pad 11 cause multiple reflections, scattering, and diffractions of the sound waves. This complex path extends the propagation distance of the sound waves within the material, increasing the chance of energy loss and thus achieving sound absorption.

[0028] The outer arc surface of the tire body 2 is provided with anti-slip grooves 13, which are equidistantly distributed on the outer surface of the tire body 2. Anti-slip rubber strips 14 are provided on the surface of the tire body 2, which are equidistantly distributed along the center point of the tire body 2 and are made of rubber.

[0029] During operation, multiple anti-slip grooves 13 are evenly spaced on the outer surface of the tire body 2. These grooves can effectively prevent slippage during the tire body 2's movement. Furthermore, the multiple anti-slip rubber strips 14 evenly distributed on the surface of the tire body 2 can increase the friction between the outer surface of the tire body 2 and the ground, thereby improving the tire's grip and providing some protection for the tire, thus achieving wear resistance.

[0030] The protrusions 3 are equidistantly distributed along the center point of the hub 1, and the protrusions 3 and the hub 1 form an integrated structure;

[0031] During operation, the multiple protrusions 3 can be used to easily install the inner support steel plates 6, which are the same number as the protrusions 3, onto the outer surface of the wheel hub 1.

[0032] The inner support steel plates 6 are evenly distributed along the center point of the hub 1, and the side of the inner support steel plates 6 away from the support seat 7 is an arc-shaped surface;

[0033] During operation, since the inner support steel plates 6 are equidistantly distributed along the center point of the wheel hub 1, and the outer surface of the inner support steel plates 6 is an arc surface, when multiple inner support steel plates 6 are installed on the outer surface of the wheel hub 1, the multiple inner support steel plates 6 will combine into a circle, and the outer arc surface of the inner support steel plates 6 will contact the inner arc surface of the tire body 2, thereby providing better support for the tire.

[0034] The inner side of the snap-fit ​​seat 8 has a threaded groove with a diameter that matches the outer diameter of the positioning bolt 9, and the snap-fit ​​seats 8 are equidistantly distributed along the center point of the hub 1.

[0035] During operation, when the snap-fit ​​seat 8 is inserted into the groove 5 opened on the inner side of the protrusion 3, the initial connection between the inner support steel plate 6 and the hub 1 can be achieved. At this time, the positioning bolt 9 passes through the inner side of the through hole 4 under the action of external force and extends into the threaded groove opened at the bottom of the snap-fit ​​seat 8. Then, rotating the positioning bolt 9 can achieve the positioning of the snap-fit ​​seat 8.

[0036] Working principle: First, the snap-fit ​​seat 8 is inserted into the groove 5. After the snap-fit ​​seat 8 and the protrusion 3 are fully engaged, the pad 10 is attached to the inner wall of the wheel hub 1, and the positioning bolt 9 passes through the hole opened on the surface of the pad 10. At the same time, the positioning bolt 9 passes through the inner side of the through hole 4 and extends into the inner side of the snap-fit ​​seat 8. At this time, the positioning bolt 9 is rotated to achieve the positioning of the snap-fit ​​seat 8, thereby achieving a stable connection between the inner support steel plate 6 and the wheel hub 1. Similarly, multiple sets of inner support steel plates 6 are installed on the outer surface of the wheel hub 1. Since the outer side of the inner support steel plate 6 is an arc surface, multiple sets of inner support steel plates 6 form a ring. Then, the tire body 2 is fitted onto the outside of the ring, and the outer arc surface of the inner support steel plate 6 contacts the inner arc surface of the tire body 2. Thus, the multiple inner support steel plates 6 and the support seat 7 can be used to support the entire tire. Moreover, the easily detachable structure makes it convenient to replace the inner support steel plate 6 later. The splicing of multiple inner support steel plates 6 makes the internal structure of the tire more stable. The design is modular, which improves overall practicality. After the multiple inner support steel plates 6 are installed, the tire body 2 can be installed on the wheel hub 1. When the tire is in motion, the noise generated during driving is transmitted through the inner side of the tire body 2 and passes through the sound insulation pad 11. The sound insulation pad 11 can be used to achieve the purpose of sound insulation. At the same time, the multiple arc-shaped grooves 12 on the inner wall of the sound insulation pad 11 make the inner wall of the entire sound insulation pad 11 wavy. When the sound wave is incident, the structure of the crests and troughs on the inner wall of the wavy sound insulation pad 11 causes the sound wave to be reflected, scattered and diffracted multiple times. This complex path is extended. Since the outer surface of the tire body 2 is provided with multiple anti-slip grooves 13 at equal intervals, the multiple anti-slip grooves 13 can be used to facilitate the anti-slip purpose during the movement of the tire body 2. In addition, the multiple anti-slip rubber strips 14 distributed at equal intervals on its surface can increase the friction between the outer surface of the tire body 2 and the ground, thereby improving the tire's grip.

[0037] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
