Description

Technical Field

[0001] This utility model relates to the field of motorcycle tire technology, specifically a motorcycle tire with a quiet and noise-reducing honeycomb tread structure. Background Technology

[0002] With the acceleration of urbanization, motorcycles are widely used as a flexible commuting tool. However, tire noise during riding has become a shortcoming in environmental interference and riding experience. Especially in noise-sensitive areas such as residential areas and schools, traditional motorcycle tires lack effective sound-dampening structures, and the noise can easily affect the surrounding life.

[0003] However, existing motorcycle tires lack a stable honeycomb system, making them prone to deformation and damage due to localized stress concentration. They exhibit poor resistance to deformation and stability, and are difficult to convert vibration energy through elastic deformation, resulting in weak noise reduction. Furthermore, they lack targeted external noise reduction design, making it difficult to reflect and block noise when it propagates to the side air, leading to significant noise pollution problems as a large amount of noise diffuses into the surrounding environment. They fail to meet the dual requirements of quietness and stability. Therefore, there is an urgent need for a motorcycle tire with a quiet and noise-reducing honeycomb tread structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a motorcycle tire with a quiet and noise-reducing honeycomb tread structure, in order to solve the problems mentioned in the background art, such as the lack of a stable honeycomb system in existing motorcycle tires, their susceptibility to deformation and damage due to local stress concentration, and the difficulty in converting vibration energy through elastic deformation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motorcycle tire with a quiet, noise-reducing honeycomb tread structure, comprising an outer tire and further comprising: An internal noise reduction component is disposed on the inner wall of the outer tire for noise reduction treatment from the inside of the outer tire; An external noise reduction component is disposed on the surface of the tire and is used to reduce noise from the outside of the tire.

[0006] Preferably, the internal noise reduction component includes an inner tube disposed on the inner wall of the outer tire, the surface of the inner tube having multiple hexagonal grooves, and the inner tube being made of nitrile rubber.

[0007] Preferably, the external noise reduction component includes two annular sound insulation strips, both of which are disposed on the surface of the tire. Two fixing grooves are formed on the surface of the tire, and the annular sound insulation strips are fixedly connected to the inner walls of the fixing grooves. The annular sound insulation strips are made of neoprene rubber.

[0008] Preferably, the inner wall of the outer tire is fixedly connected to a ply layer, the inner wall of the ply layer is fixedly connected to the inner wall of the inner tire, and the inner tire is made of high-strength polyester fiber material.

[0009] Preferably, the surface of the outer tire is provided with multiple anti-slip grooves, which are divided into two groups and are arranged symmetrically.

[0010] Preferably, the inner wall of the anti-slip groove and the surface of the curtain layer are provided with multiple micro sound-absorbing holes, and the diameter of the multiple micro sound-absorbing holes is 0.5-0.8mm.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The internal sound-dampening components create a stable honeycomb structure with multiple hexagonal grooves, preventing deformation and damage caused by localized stress concentration and improving resistance to deformation and stability. Simultaneously, the elastic deformation of the hexagonal grooves during use generates friction, converting vibration energy into heat energy, effectively absorbing and attenuating energy to reduce noise. Furthermore, the external sound-dampening components facilitate the reflection of most noise back into the tire's interior via a ring-shaped sound-absorbing strip, reducing noise diffusion into the surrounding environment and minimizing noise pollution.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 - Figure 4 The present invention provides a motorcycle tire with a quiet and noise-reducing honeycomb tread structure, including an outer tire 1, and further including: An internal noise reduction component is located on the inner wall of the outer tire 1 and is used to reduce noise from the inside of the outer tire 1. An external noise reduction component is disposed on the surface of the tire 1 for noise reduction from the outside of the tire 1. The internal sound-dampening components convert vibration energy into heat energy, effectively absorbing and attenuating the energy and reducing noise transmission. At the same time, the external sound-dampening components reflect most of the noise back into the tire 1, reducing the spread of noise to the surrounding environment and thus reducing noise pollution.

[0016] Furthermore, the internal noise reduction component includes an inner tube 201, which is disposed on the inner wall of the outer tire 1. The surface of the inner tube 201 has multiple hexagonal grooves 202. A ply layer 203 is fixedly connected to the inner wall of the outer tire 1. The inner wall of the ply layer 203 is fixedly connected to the inner wall of the inner tube 201. Through the internal noise reduction component, the multiple hexagonal grooves 202 form a stable honeycomb structure system. The stable geometry of the hexagonal grooves 202 ensures that the stress on the surface of the inner tube 201 is evenly distributed to each unit when subjected to force, avoiding deformation and damage caused by local stress concentration, and improving the deformation resistance and stability. The ply layer 203, made of high-strength polyester fiber, enhances the bonding strength between the outer tire 1 and the inner tube 201, improves the overall rigidity of the tread, ensures that the ground force is evenly transmitted during driving, avoids local stress concentration, and ensures stable grip. It should be noted that the inner tube 201 is made of nitrile rubber. The inner tube 201 made of nitrile rubber has good elastic properties, which makes it easy to cooperate with the hexagonal groove 202 to generate friction during use by elastic deformation, converting vibration energy into heat energy, realizing effective energy absorption and attenuation, thereby reducing noise. The cord layer 203 is made of high-strength polyester fiber. The high-strength polyester fiber cord layer 203 has high strength, which makes it easier to greatly enhance the bonding force between the outer tire 1 and the inner tire 201, and avoid the problem of interlayer delamination.

[0017] Furthermore, the external noise reduction component includes two annular sound insulation strips 301, both of which are disposed on the surface of the outer tire 1. Two fixing grooves 302 are formed on the surface of the outer tire 1, and the annular sound insulation strips 301 are fixedly connected to the inner wall of the fixing grooves 302. By setting the external noise reduction component, the contact point between the outer tire 1 and the ground during use is set as the center of the outer tire 1, so that the two annular sound insulation strips 301 are respectively disposed on both sides of the outer tire 1. The annular sound insulation strips 301 facilitate the blocking of noise generated by the outer tire 1.

[0018] It should be noted that the annular sound insulation strip 301 is made of neoprene rubber. The annular sound insulation strip 301 made of neoprene rubber has high density and high acoustic impedance characteristics. By setting the annular sound insulation strip 301 made of neoprene rubber, most of the noise is reflected back into the interior of the tire 1 during the process of noise propagating to the side air of the tire 1, reducing the spread of noise to the surrounding environment and thus reducing noise pollution.

[0019] Furthermore, the surface of the outer tire 1 is provided with multiple anti-skid grooves 303, which are divided into two groups and arranged symmetrically. The anti-skid grooves 303 are arranged in an "S" shape. The "S" shape of the anti-skid grooves 303 helps to slow down the airflow speed in the grooves, reduce airflow impact and eddy current generation, and reduce aerodynamic noise. The symmetrical arrangement makes the airflow distribution even and avoids local noise concentration. At the same time, the "S" shape of the anti-skid grooves 303 helps to increase the contact friction between the tire tread and the ground. The symmetrical design makes the tire tread evenly stressed and facilitates rapid drainage on wet and slippery roads, improving grip on dry and wet roads and ensuring driving safety.

[0020] Furthermore, the inner wall of the anti-slip groove 303 and the surface of the curtain layer 203 are provided with multiple micro sound-absorbing holes 204. The diameter of the multiple micro sound-absorbing holes 204 is 0.5-0.8mm. Through the arrangement of the micro sound-absorbing holes 204, the multiple micro sound-absorbing holes 204 work together to facilitate the resonance structure formed by the honeycomb unit composed of the multiple micro sound-absorbing holes 204 and the multiple hexagonal grooves 202, thereby resonating and absorbing the incoming noise, and further suppressing the propagation of aerodynamic noise.

[0021] Working principle: Through the internal noise reduction components, multiple hexagonal grooves 202 form a stable honeycomb structure system. The stable geometry of the hexagonal grooves 202 ensures that the stress on the surface of the inner tube 201 is evenly distributed to each unit when subjected to force, avoiding deformation and damage caused by local stress concentration, and improving the deformation resistance and stability. At the same time, the inner tube 201, made of nitrile rubber, has good elastic properties, which facilitates the elastic deformation and friction generated by the hexagonal grooves 202 during use, converting vibration energy into heat energy, achieving effective energy absorption and attenuation, thereby reducing noise. Secondly, the cord layer 203, made of high-strength polyester fiber, enhances the bonding strength between the outer tire 1 and the inner tube 201, improves the overall rigidity of the tread, ensures the even transmission of ground force during driving, avoids local stress concentration, and ensures stable grip.

[0022] Furthermore, by setting the external sound-dampening components, the contact point between the outer tire 1 and the ground during use is set at the center of the outer tire 1, so that two annular sound-insulating strips 301 are respectively set on both sides of the outer tire 1. The annular sound-insulating strips 301 made of neoprene rubber have high density and high acoustic impedance characteristics. By setting the annular sound-insulating strips 301, most of the noise is reflected back into the interior of the outer tire 1 during the process of noise propagating to the side air of the outer tire 1, reducing the diffusion of noise to the surrounding environment, thereby reducing noise pollution.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
