Description

Technical Field

[0001] This utility model relates to the field of tire design and manufacturing, and in particular to a low-noise tire. Background Technology

[0002] Tire design plays a crucial role in a vehicle's driving performance and the comfort of its occupants. Currently, high-profile tires, meaning tires with a higher width-to-height ratio, typically offer superior performance and stability. However, they also tend to be heavier and have a larger contact area with the air and ground. This results in increased sonic booms and tire-rim resonance noise during high-speed rotation, directly impacting occupant comfort. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem of how to reduce the noise of low-profile tires. This invention provides a tire that can effectively reduce the noise generated during tire operation.

[0004] To solve the above-mentioned technical problems, this utility model discloses a low-noise tire, comprising:

[0005] The tire crown includes a tread, the tread including a central region, the central region being arranged circumferentially;

[0006] A sidewall body, along the axial direction, is spaced apart on both sides of the tire crown away from the central region, and the sidewall body includes a shoulder;

[0007] At least one first tire tread pattern is provided along the axial direction, and the first tire tread pattern is symmetrically arranged on both sides of the central region;

[0008] Multiple second tire treads are symmetrically arranged between the first tire tread and the tire sidewall along the axial direction. The second tire treads are in the shape of an inclined triangle. Along the axial direction, one end of the second tire tread is located close to the tire shoulder, and the other end extends toward the central region.

[0009] Multiple third tire treads are symmetrically arranged on the tire shoulder along the circumferential direction.

[0010] Using the above technical solution, the first and second tire treads are distributed across the entire tire tread, and the third tire tread is located on the tire shoulder of the tire sidewall. This can suppress noise generated when the tire contacts the ground, resulting in a good noise reduction effect. The second tire tread is in the shape of an inclined triangle. Along the axial direction, one end of the second tire tread is located close to the tire shoulder, and the other end extends towards the center area. During vehicle operation, the second tire tread can guide airflow in and out, preventing airflow from impacting the tire tread and generating sonic booms, thereby reducing noise during tire operation.

[0011] According to another specific embodiment of the present invention, a low-noise tire is disclosed.

[0012] include:

[0013] A sound insulation layer, radially disposed on the side of the tire crown facing away from the tire tread;

[0014] A buffer layer is provided on the side of the sound insulation layer facing away from the tread along the radial direction, and the first tread pattern is provided around the tread along the circumferential direction, and the plurality of second tread patterns are provided at intervals on the tread.

[0015] The above technical solution has a sound insulation layer on the side of the tire crown facing away from the tread, which can prevent the rim and tire from resonating, thereby eliminating the resonance noise generated by the rim and tire. In addition, the buffer layer set on the side of the sound insulation layer facing away from the tread can play a buffering role, further disrupting the transmission of noise and improving the noise reduction effect.

[0016] According to another specific embodiment of the present invention, a low-noise tire is disclosed. The first tread includes a first groove and a second groove. Along the axial direction, the first groove and the second groove are spaced apart on both sides of the central region. Along the circumferential direction, a plurality of first reinforcing parts are spaced apart in the first groove, and a plurality of second reinforcing parts are spaced apart in the second groove, for increasing the strength of the first tread.

[0017] According to another specific embodiment of the present invention, the embodiment of the present invention discloses a low-noise tire, wherein the first reinforcing part includes a first reinforcing block, and along the axial direction, both sides of the first reinforcing block are connected to the groove wall of the first groove body. The first reinforcing block includes an inclined first guide surface, and the projection of the first guide surface on the axial direction forms a first angle with the bottom wall of the first groove body.

[0018] The second reinforcing part includes a second reinforcing block. Along the axial direction, the two sides of the second reinforcing block are connected to the wall of the second tank. The second reinforcing block includes an inclined second guide surface. The projection of the second guide surface on the axial direction forms a second angle with the bottom wall of the second tank. Both the first angle and the second angle are acute angles.

[0019] Using the above technical solution, when the tire is in motion, the first guide surface can guide the air flowing into the first groove to the outside, avoiding the air from hitting the groove wall inside the first groove and causing sonic booms; the second guide surface can guide the air flowing into the second groove to the outside, avoiding the air from hitting the groove wall inside the second groove and causing sonic booms.

[0020] According to another specific embodiment of the present invention, a low-noise tire is disclosed, wherein the first reinforcing block and the second reinforcing block are both in the shape of a square pyramid, the first guiding surface is the side surface of the first reinforcing block in the shape of a square pyramid, and the second guiding surface is the side surface of the second reinforcing block in the shape of a square pyramid.

[0021] According to another specific embodiment of the present invention, the embodiment of the present invention discloses a low-noise tire, wherein the first reinforcing part includes a third reinforcing block, the third reinforcing block is disposed on the side of the first reinforcing block opposite to the first guide surface along the circumferential direction, and the third reinforcing block is connected to the side wall of the first groove body along the axial direction.

[0022] The second reinforcing part includes a fourth reinforcing block. Along the circumferential direction, the fourth reinforcing block is disposed on the side of the second reinforcing block opposite to the second guide surface. Along the axial direction, the fourth reinforcing block is connected to the side wall of the second tank.

[0023] By adopting the above technical solution, by setting a third reinforcing block and a fourth reinforcing block in the first groove, with the third reinforcing block connected to the side wall of the first groove along the axial direction and the fourth reinforcing block connected to the side wall of the second groove along the axial direction, the strength of the central area between the first groove and the second groove can be increased, thus avoiding the impact sonic boom caused by the central area being squeezed or deformed during tire operation, thereby reducing the noise during tire operation.

[0024] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a low-noise tire, wherein along the radial direction, the height of the third reinforcing block is not higher than the height of the first reinforcing block, and the height of the fourth reinforcing block is not higher than the height of the second reinforcing block.

[0025] Using the above technical solution, the first reinforcing block can block the third reinforcing block and guide the airflow out of the interior of the first groove through the first guide surface. The second reinforcing block can block the fourth reinforcing block and guide the airflow out of the interior of the second groove through the second guide surface, thus preventing the airflow from hitting the third and fourth reinforcing blocks and generating sonic booms.

[0026] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a low-noise tire, wherein the third reinforcing block includes a first inclined surface and a second inclined surface, and the projections of the first inclined surface and the second inclined surface in the radial direction intersect and form a second included angle;

[0027] The fourth reinforcing block includes a third inclined surface and a fourth inclined surface, the projections of the third inclined surface and the fourth inclined surface in the radial direction intersect and form a third included angle.

[0028] According to another specific embodiment of the present invention, the present invention discloses a low-noise tire, wherein the plurality of second tread patterns include second tread patterns arranged symmetrically in pairs along the axial direction, each second tread pattern includes a third groove and a buffer pad, the buffer pad being slidably disposed in the third groove along a first direction.

[0029] By adopting the above technical solution, when air enters the third trough during vehicle operation, the buffer pad can slide in the first direction, which can effectively buffer and dampen the shock, reduce the impact intensity of the airflow, and thus reduce sonic boom, effectively reducing noise generation and improving driver comfort.

[0030] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a low-noise tire. Along the first direction, the groove wall of the third groove is provided with a connecting part. One end of the connecting part away from the groove wall is connected to the buffer pad. The end of the connecting part connected to the buffer pad can reciprocate along the first direction. The connecting part is provided with an elastic element. Along the first direction, one end of the elastic element is provided on the groove wall of the third groove, and the other end is connected to the buffer pad.

[0031] With the above technical solution, one end of the elastic element is located on the wall of the third groove, and the other end is connected to the buffer pad, which can further enhance the buffer pad's shock absorption capacity. When no airflow flows into the third groove, under the action of the elastic element's restoring force, both the buffer pad and the telescopic column can slide along the first direction away from the seventh side wall.

[0032] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a tire, wherein the plurality of third tread patterns include fourth grooves symmetrically arranged in pairs along the axial direction, and the fourth grooves are triangular in shape.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0044] In some embodiments, see Figure 1 , Figure 2 , Figure 3 This application provides a low-noise tire, including a tire crown 10 and a tire sidewall 20. The tire sidewall 20 includes a tire shoulder 201 and a tire sidewall 202. The tire crown 10 refers to the part of the tire that contacts the ground. The surface of the tire crown 10 that contacts the ground is the tread 11. The tread 11 includes a central region 111. The central region 111 is arranged around the tire in the circumferential direction R. The tire sidewall 20 is arranged at intervals along the axial direction X on both sides of the tire crown 10 away from the central region 111.

[0045] For example, the low-noise tire also includes a first tread pattern 30, a second tread pattern 40, and a third tread pattern 50. Along the axial direction X, multiple first tread patterns 30 are spaced apart on both sides of the central region 111, multiple second tread patterns 40 are spaced apart between the first tread patterns 30 and the sidewall body 20, and multiple third tread patterns 50 are spaced apart along the circumferential direction R on the shoulder 201. It can be understood that the first tread patterns 30, second tread patterns 40, and third tread patterns 50 not only have an aesthetic function, but also belong to the noise reduction structure of the low-noise tire provided in the embodiments of this application.

[0046] For example, see Figure 3 The low-noise tire also includes a sound insulation layer 60 and a buffer layer 70. The sound insulation layer 60 is located radially Y on the side of the crown 10 facing away from the tread 11, and the buffer layer 70 is located radially Y on the side of the sound insulation layer 60 facing away from the tread 11. The first tread pattern 30 is located circumferentially R around the tread 11, and a plurality of second tread patterns 40 are located circumferentially R spaced apart on the tread 11.

[0047] Using the above technical solution, the first tread 30 and the second tread 40 are evenly distributed on the entire tread 11, and the third tread 50 is provided on the tire shoulder 201. This can suppress the noise generated when the tire contacts the ground and has a good noise reduction effect. At the same time, a sound insulation layer 60 is provided on the side of the tire crown 10 facing away from the tread 11, which can prevent the rim and tire from resonating, thereby eliminating the resonance noise generated by the rim and tire. In addition, the buffer layer 70 provided on the side of the sound insulation layer 60 facing away from the tread 11 can play a buffering role, further disrupting the transmission of noise and improving the noise reduction effect.

[0048] In some embodiments, the low-noise tire further includes a belt protection layer 80, located radially Y, on the side of the sound insulation layer 60 facing away from the buffer layer 70. The material of the sound insulation layer 60 can be polyethylene, sponge, or other materials that provide sound insulation; the material of the buffer layer 70 can be rubber with good elasticity; the material of the belt protection layer 80 can be nylon, steel wire, etc. This application does not limit the materials of the sound insulation layer 60, buffer layer 70, and belt protection layer 80. The belt protection layer 80 is also called a support layer, hard buffer layer, or stabilizing layer, which can both mitigate impacts and tighten the tire body. Furthermore, the accompanying drawings only show the structure of the improved portion; the specific structure of each layer of the tire in the prior art is not described.

[0049] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The first tread pattern 30 includes a first groove 301 and a second groove 302. Along the axial direction X, the first groove 301 and the second groove 302 are spaced apart on both sides of the central region 111. Along the circumferential direction R, the first groove 301 has a plurality of first reinforcing parts 303 spaced apart, and the second groove 302 has a plurality of second reinforcing parts 304 spaced apart, for increasing the strength of the first tread pattern 30. Exemplarily, the first groove 301 includes a first sidewall 3011 and a second sidewall 3012, and the second groove 302 includes a third sidewall 3021 and a fourth sidewall 3022. This application embodiment does not limit the number of first tread patterns 30; for example, it can be 2, 3, 4, 5, etc., in which case the number of first grooves 301 and second grooves 302 also corresponds to 2, 3, 4, 5, etc., respectively.

[0050] In some embodiments, see Figure 2 , Figure 3 , Figure 4 and combined Figure 1The first reinforcing part 303 includes a first reinforcing block 3031 and a third reinforcing block 3032. Along the axial direction X, the two sides of the first reinforcing block 3031 are connected to the first sidewall 3011 and the second sidewall 3012 of the first groove 301. The first reinforcing block 3031 includes a first guide surface 30311 that is inclined relative to the bottom wall 3014 of the first groove 301. The first guide surface 30311 is used to guide the air flowing into the interior of the first groove 301 outward. The first guide surface 30311 intersects with the bottom wall 3014 of the first groove 301 and forms a first included angle α, which is an acute angle.

[0051] The second reinforcing part 304 includes a second reinforcing block 3041 and a fourth reinforcing block 3042. Along the axial direction X, the two sides of the second reinforcing block 3041 are connected to the third side wall 3021 and the fourth side wall 3022 of the second tank 302. The second reinforcing block 3041 includes a second guide surface 30411 that is inclined relative to the bottom wall 3024 of the second tank 302. The second guide surface 30411 is used to guide the air flowing into the second tank 302 outward. The second guide surface 30411 intersects with the bottom wall 3024 of the second tank 302 and forms a second included angle b.

[0052] For example, the first included angle α and the second included angle β can be 10°, 20°, 30°, 45°, 60°, 75°, etc., and this application does not limit the degree of the first included angle α and the second included angle β. When the tire is driving, the first guide surface 30311 can exhaust the air flowing into the first groove 301 to the outside, avoiding the air from hitting the groove wall inside the first groove 301 and causing sonic booms; the second guide surface 30411 can exhaust the air flowing into the second groove 302 to the outside, avoiding the air from hitting the groove wall inside the second groove 302 and causing sonic booms.

[0053] In some embodiments, see Figure 3 , Figure 4 and combined Figure 1 The first reinforcing block 3031 and the second reinforcing block 3041 are both in the shape of a square pyramid. The first reinforcing block 3031 includes a first guide surface 30311, a first side surface 30312, a second side surface (not shown in the figure), a third side surface (not shown in the figure), and a first bottom surface 30313. The second side surface is fitted to the bottom wall 3014 of the first tank 301. The first guide surface 30311 and the second side surface are arranged opposite each other in the radial direction Y. The first side surface 30312 and the third side surface are arranged opposite each other in the axial direction X.

[0054] The second reinforcing block 3041 includes a second guide surface 30411, a fourth side surface 30412, a fifth side surface (not shown in the figure), a sixth side surface (not shown in the figure), and a second bottom surface 30413. The fifth side surface is fitted to the bottom wall 3024 of the second tank 302. The second guide surface 30411 and the fifth side surface are arranged opposite each other in the radial direction Y, and the fourth side surface 30412 and the sixth side surface are arranged opposite each other in the axial direction X.

[0055] In some embodiments, see Figure 3 , Figure 4 and combined Figure 1 The third reinforcing block 3032 is disposed on the first bottom surface 30313 of the first reinforcing block 3031 along the axial direction X, and the third reinforcing block 3032 is connected to the first side wall 3011 and the second side wall 3012 of the first groove 301; the fourth reinforcing block 3042 is disposed on the second bottom surface 30413 of the second reinforcing block 3041 along the axial direction X, and the fourth reinforcing block 3042 is connected to the third side wall 3021 and the fourth side wall 3022 of the second groove 401.

[0056] By providing a third reinforcing block 3032 and a fourth reinforcing block 3042 within the first groove 301, with the third reinforcing block 3032 connected along the axial direction X to the first sidewall 3011 and the second sidewall 3012 of the first groove 301, and the fourth reinforcing block 3042 connected along the axial direction X to the third sidewall 3021 and the fourth sidewall 3022 of the second groove 401, the strength of the central region 111 between the first groove 301 and the second groove 302 can be increased. This prevents the central region 111 from deforming due to compression during tire operation, thus avoiding impact sonic booms with the airflow, and further reducing noise during tire operation.

[0057] For example, see Figure 3 , Figure 4 The third reinforcing block 3032 includes a first part 30321 and a second part 30322, and the fourth reinforcing block 3042 includes a third part 30421 and a fourth part 30422. The first part 30321 is disposed on the first side wall 3011, and the second part 30322 is disposed on the second side wall 3012; the third part 30421 is disposed on the third side wall 3021, and the fourth part 30422 is disposed on the fourth side wall 3022. The first part 30321, the second part 30322, the third part 30421, and the fourth part 30422 are all arranged in a triangular prism shape. It can be understood that the first part 30321, the second part 30322, the third part 30421, and the fourth part 30422 can also be other shapes such as square prisms and pentagonal prisms, and this application does not limit them.

[0058] In some embodiments, see Figure 4 and combined Figure 2Along the radial direction Y, the height of the third reinforcing block 3032 is no higher than the height of the first reinforcing block 3031, and the height of the fourth reinforcing block 3042 is no higher than the height of the second reinforcing block 3041. Thus, the first reinforcing block 3031 can block the third reinforcing block 3032, and the airflow is directed out of the interior of the first groove 301 through the first guide surface 30311. Similarly, the second reinforcing block 3041 can block the fourth reinforcing block 3042, and the airflow is directed out of the interior of the second groove 302 through the second guide surface 30411, preventing the airflow from impacting the third and fourth reinforcing blocks 3032 and causing a sonic boom.

[0059] In some embodiments, see Figure 4 The third reinforcing block 3032 includes a first inclined surface 30323 and a second inclined surface 30324, which intersect to form a third included angle c. The fourth reinforcing block 3042 includes a third inclined surface 30423 and a fourth inclined surface 30424, which intersect to form a fourth included angle d. Exemplarily, the first inclined surface 30323 is located in the first portion 30321, the second inclined surface 30324 is located in the second portion 30322, the third inclined surface 30423 is located in the third portion, and the fourth inclined surface 30424 is located in the fourth portion. The third included angle c and the fourth included angle d can be 30°, 60°, 90°, 120°, etc., and this application does not limit them.

[0060] In some embodiments, see Figure 1 , Figure 2 , Figure 5 The second tread pattern 40 is a triangular shape arranged at an angle along the axial direction X. One end of the second tread pattern 40 is located near the sidewall 20, and the other end extends towards the central region 111. In some embodiments, the plurality of second tread patterns 40 include second tread patterns 40 arranged symmetrically in pairs along the axial direction X. Each second tread pattern 40 includes a third groove 401 and a buffer pad 402. The buffer pad 402 is slidably disposed in the third groove 401 along a first direction w, which is the extension direction of the third groove 401. For example, the low-noise tire includes two rows of second tread patterns 40 arranged symmetrically along the axial direction X. Each row of second tread patterns 40 includes a plurality of second tread patterns 40. The embodiments of this application do not limit the number of second tread patterns 40. For example, it can also be 4 rows, 6 rows, 8 rows, etc.

[0061] For example, see Figure 1 , Figure 2The third tank 401 includes a fifth sidewall 4011, a sixth sidewall 4012, and a seventh sidewall 4013. The fifth sidewall 4011 and the sixth sidewall 4012 are respectively located at both ends of the seventh sidewall 4013. Along the first direction w, the fifth sidewall 4011 and the sixth sidewall 4012 intersect at the end away from the seventh sidewall 4013. The first direction w intersects with the circumferential direction R and forms a fifth included angle d. The fifth included angle d can be 30°, 60°, 90°, 120°, etc., and this application does not limit it.

[0062] In some embodiments, see Figure 1 , Figure 2 , Figure 5 Along the first direction w, the seventh sidewall 4013 of the third groove 401 is provided with a connecting part 403. One end of the connecting part 403 away from the seventh sidewall 4013 is connected to the buffer pad 402. The end of the connecting part 403 connected to the buffer pad 402 can reciprocate along the first direction w. An elastic member 404 is provided on the connecting part 403. Along the first direction w, one end of the elastic member 404 is provided on the seventh sidewall 4013 of the third groove 401, and the other end is connected to the buffer pad 402.

[0063] For example, the connecting part 403 includes a fixed post 4031 and a telescopic post 4032. Along the first direction w, one end of the fixed post 4031 is located on the seventh side wall 4013, and the other end is provided with the telescopic post 4032. The end of the telescopic post 4032 away from the fixed post 4031 along the first direction w is connected to the buffer pad 402. During tire travel, when the airflow entering the third groove 401 impacts the buffer pad 402, the buffer pad 402 slides towards the seventh side wall 4013 along the first direction w, causing the telescopic post 4032 to move towards the fixed post 4031 along the first direction w. The spring is compressed, and through the cooperation of the buffer pad 402, the connecting part 403, and the elastic member 404, the buffer effectively buffers and dampens the shock, reducing the impact intensity of the airflow, thereby reducing sonic booms, effectively reducing noise generation, and improving driver comfort. When no airflow flows into the third groove 401, under the restoring force of the elastic element 404, both the buffer pad 402 and the telescopic column 4032 can slide along the first direction w in a direction away from the seventh side wall 4013.

[0064] Exemplarily, the telescopic column 4032 can be supported by an elastic material, or a receiving groove (not shown in the figure) is provided in the fixed column 4031, and the telescopic column 4032 can reciprocate within the receiving groove along the first direction w. Exemplarily, the elastic element 404 includes a spring. It is understood that the elastic element 404 can also be other forms such as a spring sheet, and this application does not limit it in this regard.

[0065] In some embodiments, see Figure 1 , Figure 2The multiple third tread patterns 50 include fourth grooves 501 symmetrically arranged in pairs along the axial direction X, and the fourth grooves 501 are triangular in shape. It is understood that the fourth grooves 501 can also be quadrilateral, pentagonal, or other shapes, and this application does not limit this. For example, the low-noise tire includes two rows of third tread patterns 50 symmetrically arranged along the axial direction X, and each row of third tread patterns 50 includes multiple third tread patterns 50. This application does not limit the number of third tread patterns 50; for example, it can also be 4 rows, 6 rows, 8 rows, etc.

[0066] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
