Description

Technical Field

[0001] This invention belongs to the field of tire technology, specifically a novel belt layer structure for all-steel radial tires. Background Technology

[0002] Chinese patent application CN115352222A discloses a novel all-steel radial tire with a belt layer structure, comprising a carcass, a crown, two shoulders, two sidewalls, and belt layers. The belt layers include a first belt layer, a second belt layer, a third belt layer, and a fourth belt layer disposed in the middle of the crown, and zero-degree belt layers symmetrically disposed on the shoulders. The first, second, third, and fourth belt layers are sequentially bonded together radially from the carcass towards the crown in the middle of the crown. The zero-degree belt layers are circumferentially disposed at both ends of the axial direction of the third belt layer. This tire is suitable for medium- and long-distance use conditions, effectively controlling crown deformation, providing more uniform ground pressure distribution, reducing abnormal wear, and preventing early tire damage. Simultaneously, the belt layer structure enhances the strength and durability of the crown, thereby improving the tire's load capacity and impact resistance. However, this all-steel radial tire has some shortcomings in use: the tire has high overall hardness and poor elasticity; at the same time, excessive internal pressure can cause excessive stress on the tire sidewall, leading to deformation and bulges. Therefore, improvements are needed. Summary of the Invention

[0003] The purpose of this invention is to provide a novel belt layer structure for all-steel radial tires in order to solve the problems mentioned in the background art.

[0004] To address the above problems, the present invention provides a technical solution:

[0005] A novel belt layer structure for an all-steel radial tire includes a tire carcass with an adjustment mechanism. The carcass has multiple evenly distributed cavities inside. A connecting tube is fixedly connected to the inside of the carcass, communicating with the cavities. An air filling mechanism is installed on the connecting tube. A wound crown belt layer is bonded to the inside of the carcass. A segmented belt layer is bonded to the surface of the wound crown belt layer. A second belt layer is bonded to the surface of the segmented belt layer. A first belt layer is bonded to the surface of the second belt layer. A third belt layer is disposed between the segmented belt layer and the second belt layer.

[0006] Preferably, the adjusting mechanism includes a reinforcing plate fixedly connected to the tire carcass. A connecting rod is fixedly connected to the surface of the reinforcing plate, and a connecting plate is fixedly connected to the end of the connecting rod. A bidirectional screw is movably connected inside the connecting plate, and a top plate is threadedly connected to the outer side of the bidirectional screw. The top plate and the connecting rod are slidably connected, and a compression spring is provided on the outer side of the bidirectional screw. A limiting plate is fixedly connected to the surface of the tire carcass, and the limiting plate and the bidirectional screw are rotatably connected. By rotating the bidirectional screw and the top plate to perform threaded movement, the top plate compresses the compression spring, which in turn causes the connecting plate to move the reinforcing plate via the connecting rod. This results in the tire sidewall being elastically stretched, protecting the tire sidewall and preventing excessive tire pressure from causing bulges.

[0007] Preferably, one end of the compression spring is fixedly connected to the top plate, and the other end of the compression spring is fixedly connected to the connecting plate. By setting the compression spring, the connecting plate is elastically compressed.

[0008] Preferably, a retaining ring is fixedly connected to the outer side of the bidirectional screw, and the retaining ring contacts the limiting plate. By setting the retaining ring and the limiting plate in cooperation, the bidirectional screw is prevented from moving out of control.

[0009] Preferably, the inflation mechanism includes a support ring, a connecting ring fixedly connected inside the connecting pipe, a plug slidably connected inside the connecting pipe, a sliding rod fixedly connected to the surface of the plug, the sliding rod slidably connected to the connecting pipe, a guide rod fixedly connected to the surface of the plug, and a spring provided on the outer side of the guide rod. The spring provides elastic support to the plug, allowing the device to inflate the cavities through the connecting pipe and seal the connecting pipe after inflation to prevent leakage. Multiple cavities increase the tire's elasticity, resulting in better tire performance.

[0010] Preferably, a sealing ring is bonded to the outer side of the plug, and the sealing ring contacts the connecting ring. By providing the sealing ring, the sealing performance between the plug and the connecting ring is increased.

[0011] Preferably, one end of the spring is fixedly connected to the support ring, and the other end of the spring is fixedly connected to the plug. By providing the spring, the plug can be easily reset.

[0012] Preferably, a stop bar is fixedly connected to the end of the guide rod, and the stop bar contacts the support ring. The guide rod is limited by a baffle plate.

[0013] The beneficial effects of this invention are as follows: This invention relates to a novel belt layer structure for all-steel radial tires, which features greater overall tire elasticity, better cushioning during driving, and better protection of the tire sidewalls. In practical use, compared with traditional novel belt layer structures for all-steel radial tires, this novel belt layer structure for all-steel radial tires has the following beneficial effects:

[0014] First, by rotating the bidirectional screw and the top plate to make a threaded movement, the top plate compresses the compression spring, which in turn causes the connecting plate to move the reinforcing plate through the connecting rod. This causes the tire sidewall to be elastically pulled, protecting the tire sidewall and preventing excessive air pressure inside the tire from causing a bulge on the sidewall.

[0015] Secondly, the spring provides elastic support to the plug, allowing the device to inflate the cavity through the connecting pipe. After inflation, the connecting pipe is sealed to prevent leakage. Multiple cavities increase the elasticity of the tire body, resulting in better tire elasticity and improved tire performance.

[0023] like Figure 1-5As shown, the specific implementation adopts the following technical solution:

[0024] Example:

[0025] A novel belt layer structure for an all-steel radial tire includes a tire carcass 1, an adjustment mechanism 2 on the tire carcass 1, multiple evenly distributed cavities 3 inside the tire carcass 1, a connecting pipe 4 fixedly connected inside the tire carcass 1, the connecting pipe 4 communicating with the cavities 3, an air filling mechanism 5 on the connecting pipe 4, a wound crown belt layer 9 bonded inside the tire carcass 1, a segmented spliced ​​belt layer 8 bonded to the surface of the wound crown belt layer 9, a second belt layer 7 bonded to the surface of the segmented spliced ​​belt layer 8, a first belt layer 6 bonded to the surface of the second belt layer 7, and a third belt layer 10 disposed between the segmented spliced ​​belt layer 8 and the second belt layer 7.

[0026] The adjusting mechanism 2 includes a reinforcing plate 21, which is fixedly connected to the tire body 1. A connecting rod 22 is fixedly connected to the surface of the reinforcing plate 21, and a connecting plate 23 is fixedly connected to the end of the connecting rod 22. A bidirectional screw 24 is movably connected inside the connecting plate 23, and a top plate 25 is threadedly connected to the outside of the bidirectional screw 24. The top plate 25 and the connecting rod 22 are slidably connected. A compression spring 26 is provided on the outside of the bidirectional screw 24. One end of the compression spring 26 is fixedly connected to the top plate 25, and the other end of the compression spring 26 is fixedly connected to the connecting plate 23. By setting the compression spring 26, the connecting plate 23 is elastically compressed, and the tire... A limiting plate 27 is fixedly connected to the surface of the body 1. The limiting plate 27 and the bidirectional screw 24 are rotatably connected. A retaining ring 28 is fixedly connected to the outside of the bidirectional screw 24. The retaining ring 28 contacts the limiting plate 27. By setting the retaining ring 28 and the limiting plate 27 to cooperate, the bidirectional screw 24 is prevented from moving. By rotating the bidirectional screw 24 and the top plate 25 to make threaded movement, the top plate 25 compresses the compression spring 26, which in turn causes the connecting plate 23 to drive the reinforcing plate 21 to move through the connecting rod 22. This causes the tire sidewall of the tire body 1 to be elastically pulled, protecting the tire sidewall of the tire body 1 and preventing the tire sidewall from bulging due to excessive air pressure inside the tire body 1.

[0027] The gas filling mechanism 5 includes a support ring 51, a connecting ring 52 fixedly connected inside the connecting pipe 4, a plug 53 slidably connected inside the connecting ring 52, a sealing ring 54 bonded to the outside of the plug 53, the sealing ring 54 contacting the connecting ring 52, and the sealing ring 54 increasing the sealing between the plug 53 and the connecting ring 52. A sliding rod 55 is fixedly connected to the surface of the plug 53, and the sliding rod 55 is slidably connected to the connecting pipe 4. A guide rod 56 is fixedly connected to the surface of the plug 53, and a spring 57 is provided on the outside of the guide rod 56. One end of spring 57 is fixedly connected to the support ring 51, and the other end of spring 57 is fixedly connected to the plug 53. By setting spring 57, the plug 53 can be easily reset. The end of guide rod 56 is fixedly connected to a stop rod 58, which contacts the support ring 51. By setting baffle 58, guide rod 56 is limited. Spring 57 provides elastic support to plug 53, allowing the device to inflate the cavity through connecting pipe 4. After inflation, connecting pipe 4 is sealed to prevent leakage. Multiple cavities 3 increase the elasticity of tire body 1, resulting in better elasticity of tire body 1 and better tire performance.

[0028] The invention is used as follows: During use, by squeezing the plug 53, the spring 57 is elastically compressed, causing the plug 53 to separate the sealing ring 54 and the connecting ring 52. This allows the device to inflate the cavity 3 through the connecting pipe 4. The spring 57 elastically supports the plug 53, allowing the device to inflate the cavity through the connecting pipe 4. After inflation, the connecting pipe 4 is sealed to prevent leakage. Multiple cavities 3 increase the elasticity of the tire body 1, resulting in better tire elasticity and improved tire performance. Then, the bidirectional screw 24 is rotated. 4. The rotation and screw movement of the top plate 25 cause the top plate 25 to compress the compression spring 26, which in turn compresses the connecting plate 23. The connecting plate 23 drives the connecting rod 22 to move, which in turn drives the reinforcing plate 21 to move. This causes the reinforcing plate 21 to tighten the sidewall of the tire body 1. By rotating the bidirectional screw 24 and the screw movement of the top plate 25, the top plate 25 compresses the compression spring 26, which in turn causes the connecting plate 23 to drive the reinforcing plate 21 to move via the connecting rod 22. This causes the sidewall of the tire body 1 to be elastically pulled, protecting the sidewall of the tire body 1 and preventing excessive air pressure inside the tire body 1 from causing a bulge on the sidewall.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
