Description

Technical Field

[0001] The utility model relates to a detachable solid tire. Background Art

[0002] A solid tire is a type of tire corresponding to an inflated tire (hollow tire), and its tire body is solid; solid tires are generally used under high loads, requiring the rubber compound to have sufficient pressure resistance and wear resistance, with sufficiently high modulus at 100% elongation, relatively high hardness, low permanent deformation, and good wear resistance.

[0003] Solid tires are generally divided into two types: bonded and non-bonded. The former refers to a tire in which rubber is directly vulcanized onto the wheel hub, and the latter refers to a tire that is fixed to the wheel hub after vulcanization; when the tread of a solid tire is punctured, as the solid tire continues to travel, the tire will crack from the puncture point (stress concentration) and expand to the entire tire until the entire tire is scrapped, and after scrapping, the entire or whole tire needs to be replaced.

[0004] Existing problems: For a bonded solid tire, replacement requires replacing the wheel hub together, and it is necessary to disassemble and assemble the wheel hub connected to the drive shaft, which is a cumbersome process and increases the usage cost of the tire; for a non-bonded one, the tread needs to be replaced. Replacing the tread of a solid tire is not like that of an inflated tire where it can be deflated and then wrapped around the wheel hub. For a solid tire, a special device is required to expand and wrap the tread around the outer ring of the wheel hub. In most cases, the wheel hub also needs to be removed and replaced with a special device, which takes a long time to operate. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the above defects and provide a detachable solid tire.

[0006] The utility model adopts the following technical solutions:

[0020] In order to make the objectives and technical solutions of the present utility model clearer, the present utility model will be further described below with reference to the accompanying drawings and embodiments:

[0021] Embodiment 1:

[0022] As Figures 1 to 3A detachable solid tire as shown includes: a wheel hub 1, and a plurality of fixing holes 11 are provided on the side surface of the wheel hub 1; in this embodiment, there are ten fixing holes 11, and the ten fixing holes 11 are annularly and evenly distributed on the side surface of the wheel hub 1.

[0023] A tire body 2 is provided on the outer ring of the wheel hub. The tire body includes: a connecting member 21 and a tread 22; the tread 22 is fixed to the outer ring of the connecting member 21; in this embodiment, the tire body is formed by vulcanizing a rubber material to form a structure in which the tread is fixed to the outer ring of the connecting member.

[0024] In this embodiment, the connecting member is a circular ring made of metal, and the circular ring is fixedly connected to the wheel hub; the fixed connection method is to provide a plurality of mounting holes 211 on the inner ring of the circular ring. In this embodiment, there are ten mounting holes 211, and they are evenly distributed on the inner ring of the circular ring and are arranged in a paired manner with the fixing holes 11 on the side surface of the wheel hub 1, and are fixedly connected by bolts.

[0025] The process of disassembling and replacing the tire body in this embodiment is as follows:

[0026] First, rotate and remove several bolts that fix the circular ring of the old tire body to the wheel hub;

[0027] Second, separate the circular ring from the wheel hub, that is, axially separate the circular ring from the wheel hub until the wheel hub protrudes from the inner side of the tread.

[0028] Third, bring the circular ring of the new tire body close to the wheel hub until they are in close contact. At this time, the tread is located on the outer ring of the wheel hub.

[0029] Fourth, adjust the tire body so that the mounting holes of the circular ring are paired with the fixing holes of the wheel hub, install the bolts, and complete the replacement.

[0030] Embodiment 2:

[0031] As Figures 4 to 5 A detachable solid tire as shown includes: a wheel hub 1, and a plurality of fixing holes 11 are provided on the side surface of the wheel hub 1; in this embodiment, there are ten fixing holes 11, and the ten fixing holes 11 are annularly and evenly distributed on the outer ring of the wheel hub.

[0032] A tire body is provided on the outer ring of the wheel hub 1. The tire body includes: a connecting member 21 and a tread 22; the tread 22 is fixed to the outer ring of the connecting member 21; in this embodiment, the tire body is formed by vulcanizing a rubber material to form a structure in which the tread is fixed to the outer ring of the connecting member.

[0033] In this embodiment, the connecting member is a circular ring made of metal. There are ten clamping blocks 23 on the inner ring of the circular ring, and each clamping block 23 is provided with one mounting hole 211.

[0034] In this embodiment, the clamping block and the ring are integrally formed, and the overall structure makes the connecting piece more secure.

[0035] The side of the wheel hub 1 is provided with ten grooves 12, and each of the grooves 12 is provided with a fixing hole 11; each of the grooves 12 cooperates with a block 23 at a corresponding position, and each of the blocks 23 is embedded in the corresponding groove 12 (it is also possible not to set grooves, and directly set a plurality of fixing holes on the outer ring of the wheel hub to cooperate with the mounting holes on the block); the setting of the grooves 12 can make it easier for the wheel hub and the ring to align the holes, and the whole will be more secure.

[0036] The ten clamping blocks 23 of this embodiment are evenly distributed on the circular ring, so that the mounting holes 211 on the clamping blocks are matched with the fixing holes 11 of the groove 12 of the hub 1, and the mounting holes 211 and the fixing holes 11 are fixedly connected by bolts.

[0037] The process of disassembling and replacing the tire body in this embodiment is as follows:

[0038] 1. Remove the bolts that fix the old tire ring to the wheel hub by rotating it;

[0039] Second, separate the ring from the wheel hub, that is, separate the ring from the wheel hub axially until the wheel hub comes out of the inner side of the tread.

[0040] 3. Move the new tire ring close to the wheel hub, and move the grooves corresponding to each block close to each other until they are close to each other. At this time, the tread is located on the outer ring of the wheel hub.

[0041] 4. Install the bolts to complete the replacement.

[0042] In this embodiment, since a plurality of grooves cooperate with the blocks at corresponding positions, the cooperation between the wheel hub and the connecting member during the rotation of the tire is more secure, which is more conducive to enhancing the overall durability of the solid tire.

[0043] In summary, the utility model can be disassembled and assembled only by removing the bolts on the connecting parts and the wheel hub, and can realize the disassembly and replacement of the solid tire tread, without the need to disassemble and replace the wheel hub, and without the need for special equipment to expand and wrap the tread around the outer ring of the wheel hub, which saves time and reduces the cost of using the tire.
