Description

Technical Field

[0001] The invention relates to the technical field of tire preparation, in particular to a noise-reducing and shock-absorbing solid tire and a preparation method thereof. Background Art

[0002] Solid tires are a type of tire that corresponds to pneumatic tires (hollow tires). Their carcass is solid, does not use cords as a skeleton, and does not need to be inflated. They are also called airless tires. Solid tires are mainly suitable for low-speed, load-bearing vehicles. Because solid tires will not burst or leak, they are widely used in mineral mining, engineering construction, and cargo transportation. Sprinkler trucks, sweepers, and other vehicles operating at medium and low speeds on urban roads have begun to promote the use of solid tires.

[0003] Since the carcass of existing solid tires is solid, when subjected to external vibration, the solid tires will almost completely transfer the vibration force to the vehicle body itself, causing greater vibration and bumps to the vehicle body, that is, the shockproof performance of the solid tires is poor. The tire radiation noise is mainly caused by the vibration of the surrounding air caused by the vibration of the tire surface. The poor shockproof performance of solid tires leads to greater tire radiation noise. Therefore, how to make solid tires have corresponding shock absorption and noise reduction performance is a problem that existing solid tires need to solve. To this end, we propose a noise-reducing and shock-absorbing solid tire and a preparation method thereof. Summary of the invention

[0060] The cross damping block is made of a relatively soft rubber material. When the solid tire base is in operation, the solid tire base squeezes the cross damping block inside, so that the cross damping block is deformed.

[0061] The multi-sided shock-absorbing block is made of a relatively soft rubber material. When the solid tire base is in operation, the solid tire base squeezes the internal multi-sided shock-absorbing block, thereby causing the multi-sided shock-absorbing block to deform. Since the multi-sided shock-absorbing block is large in volume, when deformation and extrusion occur, it can provide a greater buffering for the vibration force received by the outer side of the solid tire base, thereby reducing the vibration of the vehicle and the noise generated by the vibration of the vehicle;

[0062] By connecting the side plates, the top and bottom of the solid tire base layer can be sealed, and sand and gravel can be prevented from entering the interior of the solid tire base layer, and the supporting strength of the solid tire base layer can be increased.

DETAILED DESCRIPTION

[0076] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0077] The present invention provides a noise-reducing and shock-absorbing solid tire and a preparation method thereof, which has the advantages of being able to greatly buffer the vibration force received by the inner and outer sides of the solid tire base layer 1, thereby reducing the vibration of the vehicle and reducing the noise generated by the vibration of the vehicle. Figure 1-12, comprising a solid tire base layer 1, a shock absorbing assembly 2, a cross shock absorbing block 3, a multilateral shock absorbing block 4, a connecting side plate 5 and a solid tire preparation device 6;

[0078] A solid tire base layer 1 is thermally connected to a variety of components. The solid tire base layer 1 uses rubber materials with good rigidity and strong wear resistance during production, so that the solid tire base layer 1 can support and operate the vehicle, and through the through grooves at the top and bottom, the cross shock-absorbing blocks 3 and the multilateral shock-absorbing blocks 4 can be thermally connected, which is convenient for installation. The solid tire base layer 1 includes: a solid tire 11, an internal groove 12, a side ear 13, a first placement groove 14, a first connection groove 15, a first functional groove 16, a second placement groove 17, a second connection groove 18 and a second functional groove 19. The solid tire 11 is installed on the outer wall of the wheel hub of the car. The internal groove 12 is arranged on the inner side of the solid tire 11, and the inner wall contacts the outer wall of the wheel hub of the car. The side ear 13 is arranged at the top and bottom of the internal groove 12 , and can limit the installed solid tire 11. After the solid tire 11 is placed and installed, the vehicle may be detached while driving. The first placement groove 14 is arranged on the inner side of the top and bottom of the solid tire 11. The first connecting groove 15 is arranged at both ends of the surface of the first placement groove 14 and can be thermally connected to the connecting side plate 5. The first functional groove 16 is arranged around the surface of the first placement groove 14 and can place the cross shock-absorbing block 3. The second placement groove 17 is arranged on the outer side of the top and bottom of the solid tire 11. The second connecting groove 18 is arranged on the outer side of the surface of the second placement groove 17 and can be thermally connected to the connecting side plate 5. The second functional groove 19 is arranged around the surface of the second placement groove 17 and can place the multilateral shock-absorbing block 4.

[0079] The shock absorbing component 2 is arranged around the outer wall of the solid tire base layer 1 and can provide corresponding buffering performance. The shock absorbing protrusions 21 of the shock absorbing component 2 can buffer the ground pressure when the vehicle is driving, thereby achieving the effect of shock absorbing the vehicle. When the solid tire base layer 1 supports the vehicle, the fold line texture block 22 contacts the ground, so that a large friction force is generated when the vehicle is driving to prevent the vehicle from sliding. The shock absorbing component 2 includes: a shock absorbing protrusion 21 and a fold line texture block 22. The shock absorbing protrusion 21 is arranged around the outer wall of the solid tire 11 and contacts the ground. The shock absorbing protrusion 21 is arranged in an arc spherical shape. When the shock absorbing protrusion 21 contacts the ground, the shock absorbing protrusion 21 is deformed to reduce the shock of the vehicle. The fold line texture block 22 is arranged around the outer wall of the solid tire 11 and between the shock absorbing protrusions 21. Through the design of the fold line texture block 22, the fold line texture block 22 contacts the ground when the vehicle is driving, thereby increasing the friction of the vehicle and preventing the vehicle from sliding.

[0080] The cross damping block 3 is thermally connected to the inner side of the solid tire base layer 1 and can cushion the tire during movement. The cross damping block 3 is made of a relatively soft rubber material. When the solid tire base layer 1 is in operation, the solid tire base layer 1 squeezes the cross damping block 3 inside, thereby deforming the cross damping block 3. The cross damping block 3 is arranged in a cross shape and has strong toughness, so that the inner side of the solid tire base layer 1 has a strong buffering capacity, thereby dispersing the vibration force, thereby reducing the vibration of the vehicle, and at the same time reducing the noise generated by the vibration of the vehicle.

[0081] The polygonal shock-absorbing blocks 4 are thermally connected to the inner side of the outer side of the solid tire base layer 1 and are placed alternately with the cross shock-absorbing blocks 3. The polygonal shock-absorbing blocks 4 are made of a softer rubber material. When the solid tire base layer 1 is in operation, the solid tire base layer 1 squeezes the internal polygonal shock-absorbing blocks 4, thereby deforming the polygonal shock-absorbing blocks 4. Since the polygonal shock-absorbing blocks 4 are relatively large in size, when deformation and squeezing occur, they can provide a greater buffer for the vibration force exerted on the outer side of the solid tire base layer 1, thereby reducing the vibration of the vehicle and the noise generated by the vibration of the vehicle.

[0082] The connecting side plate 5 is thermally connected to the top and bottom of the solid tire base layer 1, and can seal the cross shock-absorbing block 3 and the multilateral shock-absorbing block 4 placed inside, and can fill the groove. By connecting the side plates 5, the top and bottom of the solid tire base layer 1 can be sealed, and the inside of the solid tire base layer 1 can be prevented from entering sand and gravel, and the supporting strength of the solid tire base layer 1 can be increased. The connecting side plate 5 includes: a side plate connecting block 51 and a side groove 52. The side plate connecting block 51 is installed at the bottom of the connecting side plate 5 and inserted into the first connecting groove 15 and the second connecting groove 18. The side groove 52 is set at the center of the surface of the connecting side plate 5 and is on the same vertical plane as the built-in groove 12.

[0083] The solid tire preparation device 6 includes a preparation mold assembly 61, a pressing assembly 62 and a pressing top plate 63. The preparation mold assembly 61 can be used to place the mixed rubber fluid, which is convenient for limiting the shape of the solid tire and pressing the fluid. The preparation mold assembly 61 includes: a rubber mold 611, a base mold 612, a center column 613, a cross shock-absorbing groove 614, a polygonal shock-absorbing groove 615, a shock-absorbing convex groove 616, and a broken line texture groove 617. The rubber mold 611 is set on the ground and can place the mixed rubber fluid inside. The base mold 612 is set at the bottom of the rubber mold 611 and can limit the shape of the bottom of the solid tire base layer 1. The center column 613 is set It is arranged at the bottom center of the base mold 612, and can limit the shape of the side ear 13 and the built-in groove 12. The cross shock-absorbing groove 614 is arranged around the inner side of the surface of the base mold 612, and can shape the first functional groove 16 and the cross shock-absorbing block 3. The polygonal shock-absorbing groove 615 is arranged around the outer side of the surface of the base mold 612, and can shape the second functional groove 19 and the polygonal shock-absorbing block 4. The shock-absorbing convex groove 616 is arranged around the inner wall of the rubber mold 611, and can shape the shock-absorbing convex block 21. The fold line texture groove 617 is arranged around the inner wall of the rubber mold 611 and between the shock-absorbing convex grooves 616, and can shape the fold line texture block 22.

[0084] The pressing top plate 63 can be driven by the pressing component 62 to make the pressing top plate 63 close to the preparation mold component 61 to press the fluid inside the preparation mold component 61. The pressing component 62 includes: a fixed bottom plate 621, a bracket 622, a screw 623, a driving motor 624 and a movable plate 625. The fixed bottom plate 621 has an inner wall connected to the rear end of the outer wall of the base mold 612, a bracket 622, which is arranged at the rear end of the surface of the fixed bottom plate 621, a screw 623, which is rotatably connected between the brackets 622 and is arranged in two groups, and the upper end of the outer wall connects the two groups of screws 623 through a belt, a driving motor 624, which is arranged at the top of the bracket 622, and the output end is connected to the top port of the screw 623, and a movable plate 625, whose inner rear end is threadedly connected to the outer wall of the screw 623 on both sides.

[0085] By pressing the top plate 63, the fluid inside the preparation mold assembly 61 can be pressed, so that the fluid inside the preparation mold assembly 61 is pressed into a corresponding shape, and by pressing the convex block at the bottom of the top plate 6, the shape of the top of the solid tire base layer 1 can be pressed and formed. The pressing top plate 63 includes: a pressing cover plate 631 and a pressing convex edge 632. The pressing cover plate 631 has a rear end of an outer wall connected to the inner wall of the movable plate 625. The pressing convex edge 632 is arranged at the bottom of the pressing cover plate 631 and can press the fluid inside the rubber mold 611 and press and form the shape of the top of the solid tire 11.

[0086] During specific use, technicians in this field put the raw materials of synthetic rubber with wear resistance into an internal mixer for primary mixing to copolymerize the rubber and mix the rubber with the filling material, put the catalyst, accelerator, antioxidant and wear-resistant agent into the mixture in S1, mix the rubber and various additives for secondary mixing through the internal mixer, and introduce the fluid after secondary mixing into the inner periphery of the preparation mold component 61 of the solid tire preparation device 6, put the rubber raw materials with good toughness into the internal mixer, add the corresponding filling materials and additives, and pour the mixed fluid into the cross damping groove 614 and the multilateral damping groove 615 inside the preparation mold component 61, start the pressing component 62 of the solid tire preparation device 6, so that the pressing component 62 drives the pressing top plate 63 to press the fluid inside the preparation mold component 61, and let it stand for a period of time to cool the fluid and make the fluid relatively solidified. By taking out the solidified material and putting the solidified material into a vulcanizer for vulcanization operation, a solid tire base layer 1 can be obtained after the vulcanization is completed, by heating the outer wall of the vulcanized cross shock-absorbing block 3 and the inner wall of the first functional groove 16, and inserting the cross shock-absorbing block 3 into the first functional groove 16 for thermal connection, and at the same time heating the outer wall of the multilateral shock-absorbing block 4 and the inner wall of the second functional groove 19, and inserting the multilateral shock-absorbing block 4 into the second functional groove 19 for thermal connection, by heating the prepared side plate connecting block 51 at the bottom of the connecting side plate 5, and heating the inner walls of the first connecting groove 15 and the second connecting groove 18 at the top and bottom of the solid tire 11, by inserting the side plate connecting block 51 into the first connecting groove 15 and the second connecting groove 18, the connecting side plate 5 is thermally connected to the solid tire 11, thereby obtaining an assembled noise reduction and shock absorbing solid tire.
