Description

Technical Field

[0001] This utility model relates to the field of vehicle engineering technology, specifically a high-rigidity tire with a quick-installation structure. Background Technology

[0002] With the development of the automotive industry, the application of large-size tires is becoming increasingly widespread. These tires need to withstand higher loads and dynamic stresses, thus significantly increasing the rigidity requirements for the tread and sidewall sections. In traditional designs, tires typically use nylon crown belts, steel-wire-free reinforcement structures, and low-modulus tread compounds, resulting in insufficient rigidity in the tread and sidewall sections, posing safety hazards. Traditional tires rely on bolt fastening or complex mechanical structures for fixation, requiring specialized tools and considerable time for installation. Especially in field operations or emergencies, frequent tire removal and replacement is time-consuming and labor-intensive, severely impacting the connection efficiency between the rim and the tire carcass and increasing maintenance costs.

[0003] Based on this, a high-rigidity tire with a quick-installation structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide a high-rigidity tire with a quick-installation structure to solve the problem in the prior art of inconvenient quick connection between the rim and the tire body.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-rigidity tire with a quick-installation structure includes: a rim, a hub, a quick-installation mechanism, and a tire carcass unit. The hub is fixedly mounted on the central axis of the rim, and spokes are fixedly mounted on the rim. The inner wall of the rim is provided with a quick-installation mechanism for quickly installing the rim, and the outer side of the rim is fixedly provided with a tire carcass unit for contact.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative embodiment: the quick-release mechanism includes an adjusting block disposed on the inner wall of the rim, a sliding rod fixedly disposed on the top of the adjusting block, the sliding rod being slidably connected to the inner wall of the rim, sliding plates fixedly disposed on both the left and right sides of the sliding rod, the sliding plates being slidably connected to the inner wall of the rim, a first return spring fixedly disposed on the inner wall of the rim, the top of the first return spring being fixedly connected to the bottom of the sliding plate.

[0009] In one alternative: the inner wall of the adjusting block is fixedly provided with a locking unit for locking and facilitating the installation of the wheel rim.

[0010] In one alternative embodiment: the locking unit includes a limiting plate fixedly disposed on the inner wall of the adjusting block, a second return spring fixedly disposed on both sides of the limiting plate, a plug rod fixedly disposed at the end of each of the two second return springs, an mounting block fixedly disposed at the bottom of the adjusting block, and a pull rod slidably disposed on the inner wall of the mounting block.

[0011] In one alternative: the tire body unit includes a tire body fixedly disposed on the outside of the rim, a fixing seat adapted to the sliding rod is fixedly disposed on the inner wall of the tire body, and steel wire is disposed inside the tire body.

[0012] In one alternative: the inner wall of the rim is provided with a sliding groove that is adapted to the sliding rod and the sliding plate.

[0013] In one alternative: the inner wall of the adjusting block is provided with a sliding groove that matches the insert rod, the end of the insert rod is provided with a pressing ramp that matches the wheel spoke, the wheel spoke is provided with a locking groove that matches the insert rod, and the bottom of the pulling rod is provided with a slot that is the same width as the mounting block.

[0014] In one alternative: the inner wall of the tire carcass is provided with an aramid crown band, which has a double-layer cross-wound structure, and the tread of the tire carcass is made of a high-modulus formula.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model drives the adjusting block to move down by pressing down the pulling rod. The inclined structure squeezes the insert rod to slide towards the center and compresses the spring. After the rim and tire body are aligned, the spring pushes the insert rod to embed into the spoke locking groove to complete the pre-installation. Finally, the first spring resets and drives the sliding rod to insert into the tire body fixing seat to achieve a rigid connection, which significantly improves the efficiency of maintenance and replacement.

[0017] 2. This invention utilizes a high-modulus compound material, combined with aramid crown belts wrapped at a 45° angle around the sides, forming a composite reinforcement layer with steel wires. This significantly improves the rigidity of the tread and sidewalls, effectively enhancing the tire's resistance to deformation under high load conditions. Compared to traditional nylon crown belts and designs without steel wire reinforcement, this composite structure can greatly improve the overall load-bearing capacity and impact resistance of large-diameter tires, while maintaining the advantages of lightweight tire body, and balancing handling stability and service life.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4 As shown, a high-rigidity tire with a quick-installation structure includes: a rim 1, a hub 2, a quick-installation mechanism, and a tire carcass unit. The hub 2 is fixedly mounted on the central axis of the rim 1. A spoke 3 is fixedly mounted on the rim 1. The inner wall of the rim 1 is provided with a quick-installation mechanism for quickly installing the rim 1. The outer side of the rim 1 is fixedly provided with a tire carcass unit for contact.

[0025] In one embodiment, such as Figure 2 and Figure 3 As shown, the quick-installation mechanism includes an adjusting block 4 disposed on the inner wall of the rim 1. A sliding rod 5 is fixedly disposed on the top of the adjusting block 4. The sliding rod 5 is slidably connected to the inner wall of the rim 1. Sliding plates 6 are fixedly disposed on both the left and right sides of the sliding rod 5. The sliding plates 6 are slidably connected to the inner wall of the rim 1. A first return spring 7 is fixedly disposed on the inner wall of the rim 1. The top end of the first return spring 7 is fixedly connected to the bottom end of the sliding plate 6. A locking unit for locking and facilitating the installation of the rim 1 is fixedly disposed on the inner wall of the adjusting block 4.

[0026] The inner wall of the rim 1 is provided with a sliding groove that matches the sliding rod 5 and the sliding plate 6, so that the sliding rod 5 and the sliding plate 6 can slide up and down the inner wall of the rim 1 for adjustment.

[0027] The locking unit includes a limiting plate 8 fixedly disposed on the inner wall of the adjusting block 4. A second return spring 9 is fixedly disposed on both sides of the limiting plate 8. A plug rod 10 is fixedly disposed at the end of each of the two second return springs 9. An installation block 11 is fixedly disposed at the bottom of the adjusting block 4. A pull rod 12 is slidably disposed on the inner wall of the installation block 11.

[0028] The inner wall of the adjusting block 4 is provided with a sliding groove that matches the insert rod 10, facilitating the left and right sliding of the insert rod 10. The end of the insert rod 10 is provided with a pressing ramp that matches the spoke 3, so that when the adjusting block 4 moves the insert rod 10 downward, it presses the insert rod 10 to slide towards the center, while compressing the second return spring 9. The spoke 3 is provided with a locking groove that matches the insert rod 10, so that the insert rod 10 can be inserted into the locking groove, making it easy for the operator to install the rim 1 onto the tire body 13. The bottom of the pulling rod 12 is provided with a slot with the same width as the mounting block 11, so that when the pulling rod 12 is pressed down, the pulling rod 12 can be inserted into the slot on the mounting block 11, making it easier to bear force. After the installation is completed, the pulling rod 12 can be removed by sliding it on the inner wall of the mounting block 11, making it convenient for tire use.

[0029] By pressing down the pull rod 12 and causing the adjusting block 4 to slide downwards, the adjusting block 4 causes the sliding rod 5 to slide downwards. Simultaneously, the sliding rod 5 causes the sliding plate 6 to move downwards and compress the first return spring 7. As the adjusting block 4 descends, the spoke 3 compresses the compression ramp at the end of the insert rod 10, causing it to slide towards the center, while simultaneously compressing the second return spring 9. The second return spring 9 then causes the insert rod 10 to return to its original position and engage in the locking groove on the spoke 3. At this point, the sliding rod 5 is fully retracted into the rim 1, allowing the operator to easily install the rim 1 onto the tire body 13. The locking of the insert rod 10 is then manually released. The first return spring 7 then causes the sliding rod 5 and the sliding plate 6 to return to their original positions, allowing the sliding rod 5 to insert into the fixing seat 14 located on the inner wall of the tire body 13, completing the quick installation.

[0030] In one embodiment, such as Figure 4 As shown, the tire body unit includes a tire body 13 fixedly disposed on the outside of the rim 1, a fixing seat 14 adapted to the sliding rod 5 is fixedly disposed on the inner wall of the tire body 13, and a steel wire 15 is disposed inside the tire body 13.

[0031] The inner wall of the carcass 13 is provided with an aramid crown band, which has a double-layer cross-wound structure; the tread of the carcass 13 is made of a high-modulus compound.

[0032] The tread of the carcass 13 uses a high-modulus compound with an E* of 10 MPa at 30°C. Indoor testing has verified that this compound increases the CP (Constant Pressure) under high load by approximately 5%, significantly enhancing tread rigidity. An aramid crown belt is wrapped around the side of the carcass 13 at a 45° angle, forming a composite reinforcement layer with the steel wire 15, effectively improving side rigidity. Compared to traditional nylon crown belts and tires without steel wire reinforcement, this invention significantly improves side rigidity through the aramid crown belt (increasing CP by 3-8%) and steel wire reinforcement (increasing CP by 1-2%), ensuring the safety of large-diameter tires.

[0033] The above embodiment discloses a high-rigidity tire with a quick-installation structure. When the operator presses down on the pull rod 12, the adjusting block 4 moves vertically downwards along the inner wall of the rim 1. Simultaneously, the sliding rod 5 and sliding plate 6 move downwards, compressing the first return spring 7. During the downward movement of the adjusting block 4, its inclined structure presses against the compression ramp at the end of the insert rod 10, forcing the insert rod 10 to slide towards the center and compress the second return spring 9. When the rim 1 and tire body 13 are aligned, the second return spring 9 pushes the insert rod 10 to return to its original position, its end precisely embedding into the locking groove of the spoke 3, allowing the sliding rod 5 to fully retract into the rim 1, achieving quick pre-installation of the rim 1 and tire body 13. After installation, the locking state of the insert rod 10 is released, and the first return spring 7 pushes the sliding rod 5 and sliding plate 6 to return to their original positions. The sliding rod 5 inserts into the fixing seat 14 on the inner wall of the tire body 13, achieving quick installation of the rim 1 and tire body 13. The tread of the carcass 13 uses a high-modulus compound with an E* of 10 MPa at 30°C. Indoor testing has verified that this compound increases the CP (Constant Pressure) under high load by approximately 5%, significantly enhancing tread rigidity. An aramid crown belt is wrapped around the side of the carcass 13 at a 45° angle, forming a composite reinforcement layer with the steel wire 15, effectively improving side rigidity. Compared to traditional nylon crown belts and tires without steel wire reinforcement, this invention significantly improves side rigidity through the aramid crown belt (increasing CP by 3-8%) and steel wire reinforcement (increasing CP by 1-2%), ensuring the safety of large-diameter tires.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
