Description

Technical Field

[0001] This utility model belongs to the field of tires, and in particular relates to a solid tire with high wear resistance. Background Technology

[0002] Tires are annular, elastic rubber products fitted onto various vehicles or machinery for rolling on the ground, primarily serving to support the vehicle body and cushion external impacts. Tires are mainly divided into pneumatic tires and solid tires. Solid tires, as opposed to pneumatic or hollow tires, have a solid carcass, do not use cords as a skeleton, do not require inflation, and are characterized by wear resistance and high load-bearing capacity. They are widely used in industrial vehicles, often in low-speed, high-load vehicles or machinery, such as forklifts. However, existing solid tires are prone to problems such as rapid tread wear and insufficient anti-skid performance under prolonged high-load use, affecting their service life and safety. Therefore, a solid tire with higher wear resistance and anti-skid performance is needed.

[0003] For example, Chinese patent literature discloses a special vehicle wear-resistant solid tire [patent application number: CN201921204789.7], which includes a rim and a rubber block. The side wall of the rim is provided with a mating groove, and several positioning blocks are fixedly connected to the bottom of the mating groove. The inner side walls of the rim are provided with mounting grooves, and sliding blocks are slidably connected in the mounting grooves. A spring is fixedly installed on one end of the sliding block and the mounting groove. The side walls of the rubber block are provided with fixing grooves. Two layers of metal mesh are horizontally laid inside the rubber block. Several metal wires are vertically connected inside the rubber block. The bottom end of the rubber block is provided with a positioning groove. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems by providing a solid tire with high wear resistance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A solid tire with high wear resistance includes a solid tire carcass and a support ring embedded in the solid tire carcass. The support ring has an insertion cavity, and a portion of the solid tire carcass extends into the insertion cavity. The support ring has several through holes, and double-ended bolts pass through the through holes. The double-ended bolts pass through the portion of the solid tire carcass that extends into the insertion cavity. A wear-resistant layer is provided on the outer surface of the solid tire carcass, and a wear-resistant structure is provided on the outer surface of the wear-resistant layer.

[0007] In the aforementioned solid tire with high wear resistance, the solid tire body is also provided with several through holes, each through hole corresponding to a perforation hole. The through holes and the corresponding perforation holes are connected and configured, and each through hole is equipped with a double-ended bolt. The double-ended bolt passes through the perforation hole and the portion of the solid tire body that extends into the embedded cavity.

[0008] In the aforementioned solid tire with high wear resistance, the inner diameter of the through hole is larger than the outer diameter at the end of the double-ended bolt.

[0009] In the aforementioned solid tire with high wear resistance, a cushioning and shock-absorbing structure is also provided in the solid tire body, and the cushioning and shock-absorbing structure is connected to the wear-resistant layer.

[0010] In the aforementioned solid tire with high wear resistance, the shock absorption structure includes several shock absorption chambers arranged in a circular array along the solid tire body. The opening of each shock absorption chamber abuts against the inner wall of the wear-resistant layer. Each shock absorption chamber is equipped with a shock absorption spring or foamed rubber, which abuts against the inner wall of the wear-resistant layer.

[0011] In the aforementioned solid tire with high wear resistance, the shock absorption structure also includes reinforcing ribs arranged on both sides of each shock absorption cavity.

[0012] In the aforementioned solid tire with high wear resistance, the wear-resistant structure includes several sets of anti-skid structures disposed on the outer surface of the wear-resistant layer away from the solid tire body. The several sets of anti-skid structures are arranged in a circular array along the wear-resistant layer. The anti-skid structure includes a straight anti-skid arc block, and an oblique anti-skid arc block is provided on each side of the straight anti-skid arc block. The two oblique anti-skid arc blocks are placed in opposite directions.

[0013] In the aforementioned solid tire with high wear resistance, the wear-resistant structure further includes a side anti-slip block disposed on the side of the wear-resistant layer, one end of which extends to the outer surface of the wear-resistant layer away from the solid tire body.

[0014] In the aforementioned solid tire with high wear resistance, the side of the solid tire body is also provided with several side anti-slip blocks.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1. The solid tire body extends into the embedded cavity and is reinforced and fixed by double-headed bolts to increase the stability of the connection. The wear-resistant structure increases the wear resistance of the solid tire.

[0017] 2. The shock-absorbing springs or foamed rubber are used to offset the impact force received by the wear-resistant layer, which can play a role in shock absorption when passing through uneven road surfaces.

[0018] 3. The reinforcing ribs can support the damping springs or foam rubber in the damping cavity, and reduce the degree of deformation of the damping springs or foam rubber to both sides when they deform. On the other hand, they also increase the support force on the wear-resistant layer.

[0019] 4. The friction between the anti-slip blocks and the ground is increased by using straight anti-slip arc blocks, angled anti-slip arc blocks, and side anti-slip blocks to prevent slipping. In addition, the thickness of the wear-resistant layer is indirectly increased by using straight anti-slip arc blocks, angled anti-slip arc blocks, and side anti-slip blocks to improve wear resistance.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides a solid tire with high wear resistance, combined with Figure 1-4 As shown, the device includes a solid tire body 10 and a support ring 11 embedded in the solid tire body 10. The support ring 11 has an embedded cavity 12, and a portion of the solid tire body 10 extends into the embedded cavity 12. The support ring 11 has several through holes 13, and a double-ended bolt 14 passes through the through holes 13. The double-ended bolt 14 passes through the portion of the solid tire body 10 that extends into the embedded cavity 12. The outer surface of the solid tire body 10 is provided with a wear-resistant layer 15, and the outer surface of the wear-resistant layer 15 is provided with a wear-resistant structure 16.

[0027] In this embodiment, the solid tire body 10 extends into the embedded cavity 12 and is reinforced and fixed by the double-ended bolt 14 to increase the stability of its connection, and the wear-resistant structure 16 increases the wear resistance of the solid tire.

[0028] The solid tire body 10 is also provided with several through holes 17, each through hole 17 corresponding to a through hole 13. The through holes 17 and the corresponding through holes 13 are connected and configured. Each through hole 17 is equipped with a double-headed bolt 14, which penetrates the through hole 13 and the portion of the solid tire body 10 that extends into the embedded cavity 12.

[0029] In this embodiment, the connection between the solid tire body 10 and the support ring 11 is further strengthened.

[0030] The inner diameter of the through hole 17 is larger than the outer diameter at the end of the double-ended bolt 14.

[0031] In this embodiment, when replacing the solid tire body 10, the wrench can enter the through hole 17 and hold the double-ended bolt 14 for disassembly, making it convenient to replace the tire.

[0032] The solid tire body 10 is also provided with a buffer and shock absorption structure, which is connected to the wear-resistant layer 15.

[0033] In this embodiment, the buffer and shock-absorbing structure can play a role in shock absorption, and in addition, it can also support the wear-resistant layer 15.

[0034] The aforementioned buffer and shock-absorbing structure includes several shock-absorbing cavities 18, which are arranged in a circular array along the solid tire body 10. The opening of each shock-absorbing cavity 18 abuts against the inner wall of the wear-resistant layer 15. Each shock-absorbing cavity 18 is provided with a shock-absorbing spring 19 or foamed rubber, which abuts against the inner wall of the wear-resistant layer 15.

[0035] In this embodiment, the shock-absorbing spring 19 or foamed rubber is used to offset the impact force received by the wear-resistant layer 15, which can play a shock-absorbing role when passing through uneven road surfaces.

[0036] The aforementioned buffer and shock-absorbing structure also includes reinforcing ribs 20 disposed on both sides of each shock-absorbing cavity 18.

[0037] In this embodiment, the reinforcing rib 20 can support the damping spring 19 or foamed rubber in the damping cavity 18, and reduce the degree of deformation of the damping spring 19 or foamed rubber to both sides when the damping spring 19 or foamed rubber deforms. On the other hand, it also increases the support force on the wear-resistant layer 15.

[0038] The wear-resistant structure 16 includes several sets of anti-slip structures disposed on the outer surface of the wear-resistant layer 15 away from the solid tire body 10. The several sets of anti-slip structures are arranged in a ring array along the wear-resistant layer 15. The anti-slip structure includes a straight anti-slip arc block 21. An oblique anti-slip arc block 22 is provided on each side of the straight anti-slip arc block 21. The two oblique anti-slip arc blocks 22 are placed in opposite directions.

[0039] The wear-resistant structure 16 also includes a side anti-slip block 23 disposed on the side of the wear-resistant layer 15, one end of which extends to the outer surface of the wear-resistant layer 15 away from the solid tire body 10.

[0040] The solid tire body 10 is also provided with several side anti-slip blocks 23 on its side.

[0041] In this embodiment, the friction between the anti-slip arc block 21, the oblique anti-slip arc block 22, and the side anti-slip block 23 are used to increase the friction with the ground and prevent slipping. The anti-slip arc block 21, the oblique anti-slip arc block 22, and the side anti-slip block 23 are also used to indirectly increase the thickness of the wear-resistant layer 15 and improve wear resistance.
