Description

Technical Field

[0001] The present invention relates to the technical field of tire patterns, and in particular to a pattern structure of an RT tire and a pattern processing device thereof. Background Art

[0002] Tire patterns are various longitudinal, transverse and diagonal grooves on the tire tread. Their main functions include increasing the friction between the tire and the ground, reducing tire noise, dissipating heat and water from the tire, improving vehicle handling performance and appearance, etc.

[0003] In the existing technology, tire pattern design is mostly single-function oriented, often sacrificing other performances when improving a certain performance. For example, the deep grooves and nail hole structures designed to enhance snow grip may lead to poor drainage on slippery roads, increasing the risk of hydroplaning; while the fine grooves designed to optimize drainage performance are easily blocked by mud on muddy roads and lose traction. Existing processing equipment also mostly uses a single mold molding technology, which makes it difficult to achieve precise manufacturing of complex pattern blocks. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1 , the present invention provides a technical solution:

[0034] A tread structure of an RT tire, comprising:

[0035] A tire, wherein a first shoulder pattern group 1 and a second shoulder pattern group 4 are respectively distributed on the left and right sides of the surface of the tire, and a first central pattern group 2, a second central pattern group 3, a third central pattern group 5 and a fourth central pattern group 6 are sequentially distributed between the first shoulder pattern group 1 and the second shoulder pattern group 4;

[0036] The first shoulder pattern group 1 is provided with a first pattern block 101 and a second pattern block 105, both of which are provided with nail holes 102 and a first steel sheet 106, a pattern rib 103 is provided between the first pattern block 101 and the second pattern block 105, a longitudinal pattern groove 104 is provided on the second pattern block 105, and the first pattern block 101 and the second pattern block 105 are arranged at intervals in a circumferential manner.

[0037] Specifically, the second shoulder pattern group 4 is provided with a first pattern block 101 and a second pattern block 105, both of which are provided with nail holes 102 and a first steel sheet 106, a pattern rib 103 is provided between the first pattern block 101 and the second pattern block 105, and a longitudinal pattern groove 104 is provided on the second pattern block 105. The first pattern block 101 and the second pattern block 105 are arranged at intervals in a circumferential manner, and the nail holes 102 and the pattern grooves 104 of the second shoulder pattern group 4 are staggered with the nail holes 102 and the pattern grooves 104 of the first shoulder pattern group 1.

[0038] Specifically, the first central pattern group 2 and the second central pattern group 3 are both in the shape of maple leaves, the first central pattern group 2 and the second central pattern group 3 are arranged 180 degrees apart, and the first central pattern group 2 and the second central pattern group 3 are both installed with a second steel sheet 201 .

[0039] Specifically, the third central pattern group 5 and the fourth central pattern group 6 are both in a blade shape, and the third central pattern group 5 and the fourth central pattern group 6 are arranged 180 degrees off-set, and the third central pattern group 5 and the fourth central pattern group 6 are distributed and installed with a third steel sheet 501 and a fourth steel sheet 601.

[0040] Specifically, the first shoulder pattern group 1, the second shoulder pattern group 4, the first central pattern group 2, the second central pattern group 3, the third central pattern group 5 and the fourth central pattern group 6 all adopt a stepped pattern design, and the bottom of the pattern group is 2 mm wider than the top.

[0041] In this embodiment, the left and right sides of the tread surface of the tire are respectively provided with a first shoulder pattern group 1 and a second shoulder pattern group 4, and the first to fourth central pattern groups 6 are sequentially spaced in the circumferential direction between the two, wherein the first and second shoulder pattern groups 4 adopt a symmetrical and staggered functional design, and each shoulder pattern group includes a first pattern block 101 and a second pattern block 105 arranged at intervals in the circumference, and the surface of the pattern block is provided with a nail hole 102 and an embedded first steel sheet 106, the nail hole 102 is used to adapt to the installation of snow anti-skid spikes, and the first steel sheet 106 is embedded in the first steel sheet 106. The sheet 106 is embedded in the rubber matrix through a hot melt die-casting process to enhance the shear strength of the pattern block; adjacent pattern blocks are connected by radial pattern ribs 103, and the height of the ribs is lower than the pattern block to form a self-cleaning gap. A longitudinal S-shaped groove with a depth of is opened on the second pattern block 105, and the end of the groove forms an angle of 30°-45° with the nail hole 102, so that the shoulder area produces a rotary cutting effect on muddy roads to quickly peel off the attached silt. At the same time, the staggered arrangement of the nail hole 102 and the groove effectively disperses the water flow path and improves wet grip.

[0042] The first central pattern group 2 and the second central pattern group 3 are maple leaf-shaped three-dimensional structures, with a serrated edge with a chamfer of 15° at the end of the blade, and a second steel sheet 201 with a thickness of 1.2 mm embedded in the base of the blade. The two groups of patterns are symmetrically distributed at 180° to balance the circumferential stress. The third central pattern group 5 and the fourth central pattern group 6 are blade-type streamlined shapes, with an arc-shaped protrusion on the leading edge and a three-dimensional groove with a gradually changing width at the rear. The third and fourth special-shaped steel sheets 601 (the third steel sheet 501 is wavy, and the fourth steel sheet 601 is a trapezoidal cross-section) are embedded inside the blade, and the two groups of blade patterns are also arranged with a 180° phase difference. This combined design enables the maple leaf-shaped pattern to improve traction through multi-directional engagement under low-speed off-road conditions, while the blade-shaped pattern enhances drainage efficiency through groove directional diversion when driving at high speed on paved roads, and combined with the differentiated stiffness distribution of the steel sheets, the ground pressure is evenly distributed in the full speed range of 40-120km / h.

[0043] In this embodiment, the entire tread adopts a stepped hierarchical structure, and the bottom width of each pattern group is 2mm wider than the top, forming a trapezoidal cross-section with a bottom width of 8mm and a top width of 6mm. The step surface is inclined at an angle of 5°-8° to the tread centerline. While enhancing the tread rigidity, the stepped inclined surface guides road debris to both sides for discharge. Combined with the micro-guide grooves at the bottom of the pattern blocks (groove depth 0.5mm, width 1mm), the stone sticking rate can be reduced, making it easier for the tire to throw out mud and water when driving on muddy roads. After the tire is worn out by half, due to the trapezoidal design, the pattern area becomes larger, avoiding the problem of excessive wear of the tire in the later stage. At the same time, the pattern design shortens the braking distance on snow and improves the traction efficiency on muddy roads, combining all-terrain passability with highway economy.

When engraving is performed, the driving structure 11 can drive the tire embryo 13 to rotate, so that the milling cutter 25 does not need to rotate, and at the same time, the engraving part is heated in cooperation with the heating tube 19. After the engraving is completed, the inflation port 1202 is opened to quickly deflate the inflation belt 1201, and the engraved tire embryo 13 can be taken out to enter the subsequent process. The tire embryo 13 can be quickly fixed through the inflation belt 1201 without the use of tools, thereby reducing labor intensity.

The inflation port 1202 is connected to the air pump 10 through an air pipe 1001.

[0051] In this embodiment, the tool holder 20 is sleeved on the screw rod 17 and the guide rod 18. The screw rod 17 is driven by a motor hidden in the electric slider 15. Due to the guide rods 18 on both sides, after the screw rod 17 rotates, the tool holder 20 can achieve left and right translation according to the steering direction, so that the milling cutter 25 can engrave different positions on the surface of the tire blank 13. At the same time, a steering motor 21 is provided under the tool holder 20, and the lower end of the steering motor 21 is connected to an adjustment box 23. The adjustment box 23 is used to adjust the elevation angle of the milling cutter 25.

The outer diameter of the fixed hub 12 is smaller than the inner diameter of the tire blank 13. The staff can directly place the tire blank 13 above the fixed hub 12. An inflatable belt 1201 is installed on the fixed hub 12, and an inflatable port 1202 is opened on the side. The inflatable port 1202 is connected to an external air pump 10 through an air pipe 1001. After the embryo is placed, the air pump 10 is started. The air pump 10 quickly inflates the inflatable belt 1201, so that the inflatable belt 1201 expands rapidly, so that the outer side of the inflatable belt 1201 is tightly fitted with the inner circle of the embryo, thereby quickly fixing the tire blank 13. The fixed hub 12 is connected to the driving structure 11. When engraving is performed, the driving structure 11 can drive the tire blank 13 to rotate, so that the milling cutter 25 does not need to rotate, and at the same time, the engraving part is heated in cooperation with the heating tube 19. After the engraving is completed, the engraving is completed. The inflation port 1202 is opened to quickly deflate the inflation belt 1201, and the engraved tire blank 13 can be taken out to enter the subsequent process. The tire blank 13 can be quickly fixed by the inflation belt 1201 without using tools, which reduces labor intensity. The tool holder 20 is sleeved on the screw rod 17 and the guide rod 18.
