Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically a quiet tire with noise reduction function. Background Technology

[0002] More stringent requirements have been placed on driving comfort, especially on vehicle noise. Vehicle noise mainly comes from the power transmission system, aerodynamic noise, tires, and vehicle parts. Tire noise includes external noise and internal cavity noise, among which cavity noise is the noise factor that has the greatest impact on vehicle comfort.

[0003] According to the utility model patent application CN221819817U, a quiet tire is disclosed, including a tire body, a noise-reducing component, and an adhesive component. The tire body includes an inner circumferential surface defining a cavity within the tire body. The noise-reducing component extends circumferentially along the tire body and covers at least a portion of the inner circumferential surface. Although this device improves the structure of the adhesive component, with the two adhesive components complementing each other and achieving full-time adhesion between the noise-reducing component and the inner circumferential surface of the tire body, preventing displacement and detachment of the noise-reducing component, when the quiet tire is punctured by a foreign object and needs repair, the noise-reducing component and adhesive component inside the tire must be manually removed before the tire can be repaired. After repair, the noise-reducing component needs to be glued to the inner wall of the quiet tire using the adhesive component, thus increasing the repair cost and making repair more complicated, thereby affecting the use of the quiet tire. Therefore, we provide a quiet tire with noise reduction function to solve the above problems. Utility Model Content

The bottom end of the inflation tube passes through the tire body and extends into the interior of the tire body, while the top end of the inflation tube passes through the tire body and the wheel hub in sequence and extends into the interior of the wheel hub.

[0013] Compared with existing technologies, this noise-reducing silent tire has the following beneficial effects: This invention, through the combination of a tire body, mounting box, mounting block, mounting arc plate, and sound insulation cotton, allows for convenient installation of the mounting box fixed inside the tire body. The mounting block, fixed on one side of the mounting arc plate, is then inserted into the mounting box, enabling the sound insulation cotton, fixed on the other side of the mounting arc plate, to be installed inside the tire body. Because the four sound insulation cotton pieces are installed close together, with one side of each piece contacting the outer surface of the wheel hub, the sound insulation cotton is stably installed inside the tire body. Furthermore, the combination of wedge blocks and locking grooves allows for further installation of the sound insulation cotton inside the tire body by having two wedge blocks engage with two locking grooves. This facilitates the removal and installation of the sound insulation cotton inside the silent tire, reducing maintenance costs and simplifying its maintenance and use. Attached Figure Description

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] This embodiment provides a quiet tire with noise reduction function. The device is used to drive quietly on the road using the quiet tire with noise reduction function. It can easily remove and install the sound insulation cotton inside the quiet tire, thereby reducing the maintenance cost of the quiet tire and facilitating the maintenance and use of the quiet tire.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A noise-reducing silent tire includes a tire body 1. The tire body 1 uses low-noise tire materials, such as polymer materials or high-viscosity rubber, to reduce friction noise when the tire contacts the ground. Auxiliary mechanisms 2 are provided on both sides and inside the tire body 1. Noise-reducing mechanisms 3 are provided inside and outside the tire body 1. A wear-resistant strip 301 is fixedly connected to the outer surface of the tire body 1. The wear-resistant strip 301 is made of ultra-high molecular weight polyethylene with a wear resistance of PA66. Several irregular tread grooves 302 are formed on the outer surface of the wear-resistant strip 301. The wear-resistant strip 301 improves the wear resistance of the silent tire. The multiple irregular tread grooves 302 on the outer surface of the wear-resistant strip 301 can reduce resonance and noise generated when the tire contacts the ground. The irregular tread grooves 302 can disperse the contact points and reduce continuous vibration.

[0022] Reference Figure 3 and Figure 4 The noise reduction mechanism 3 includes mounting boxes 303 arranged in a circular pattern at equal intervals. The sides of several mounting boxes 303 that are far apart from each other are fixedly connected to the inner wall of the tire body 1. The inner wall of the tire body 1 is fixedly connected with lower Velcro straps 308 arranged in a circular pattern at equal intervals. The sides of several lower Velcro straps 308 that are close to each other are provided with upper Velcro straps 309. The upper Velcro straps 309 are attached to the lower Velcro straps 308 by the multiple lower Velcro straps 308 fixed to the inner wall of the tire body 1, thereby facilitating the installation of the noise reduction structure.

[0023] Reference Figure 2 , Figure 3 and Figure 4Each mounting box 303 has a mounting block 305 snapped into its interior. A mounting arc plate 306 is fixedly connected to one side of each mounting block 305 that is close to each other. The opposite sides of the mounting arc plates 306 contact the opposite sides of each mounting box 303 that are close to each other. Two wedge-shaped blocks 307 are fixedly connected to the opposite sides of each mounting arc plate 306. Each mounting box 303 has snap-fit ​​grooves 304 on both sides. The two sets of wedge-shaped blocks 307 snap into the two sets of snap-fit ​​grooves 304 respectively. The opposite sides of the mounting arc plates 306 that are close to each other... Sound insulation cotton 311 is fixedly connected, and several sound insulation cotton 311 are in contact with each other on their close sides. Several upper Velcro straps 309 are fixedly connected to each other on their close sides. Several silent airbags 310 are in contact with each other on their close sides and the sides of several sound insulation cotton 311 are in contact with each other on their far sides. By using the adhesive cooperation of upper Velcro straps 309 and lower Velcro straps 308, the silent airbags 310 can be installed between the tire body 1 and the sound insulation cotton 311. The silent airbags 310 can absorb low-frequency vibrations, reduce noise, and further improve the noise reduction performance of the silent tire.

[0024] Reference Figure 1 and Figure 2 The auxiliary mechanism 2 includes a hub 201. The hub 201 is made of lightweight material, which can reduce the vibration of the hub 201 and thus reduce noise. Several sound insulation cotton 311 are close to each other on one side and contact the outer surface of the hub 201. The inner wall of the tire body 1 is in contact with the outer surface of the hub 201. By setting the hub 201 of lightweight material, the noise reduction performance of the quiet tire can be improved, and several sound insulation cotton 311 are installed between the tire body 1 and the hub 201.

[0025] Reference Figure 1 Both sides of the wheel hub 201 are fixedly connected with blocking rings 202. The side of the two blocking rings 202 that are close to each other are in contact with the two sides of the tire body 1. Through the blocking rings 202, the tire body 1 can be stably fitted onto the outside of the wheel hub 201, thereby forming the body of the silent tire.

[0026] Reference Figure 1 A mounting bracket 203 is fixedly connected to the inner wall of the hub 201, and a rotating shaft 204 is fixedly connected to the inner wall of the mounting bracket 203. By utilizing the cooperation between the mounting bracket 203 and the rotating shaft 204, the main body of the quiet tire can be installed on both ends of the vehicle drive shaft, thereby facilitating the use of the main body of the quiet tire.

[0027] Reference Figure 1 , Figure 2 and Figure 3An inflation tube 205 is attached to the inside of the wheel hub 201. The bottom end of the inflation tube 205 passes through the tire body 1 and extends into the interior of the tire body 1. The top end of the inflation tube 205 passes through the tire body 1 and the wheel hub 201 in sequence and extends into the interior of the wheel hub 201. By fixing the inflation tube 205 to the inner wall of the tire body 1 and passing through the wheel hub 201, it is convenient to inflate the tire body 1.

[0028] Working principle: When using this noise-reducing tire, first hold the fully inflated noise-reducing airbag 310 manually so that the upper Velcro 309 fixed on one side of the noise-reducing airbag 310 can be glued together with the lower Velcro 308 fixed on the inner wall of the tire body 1, so that the noise-reducing airbag 310 can be installed on the inner side of the tire body 1.

[0029] Next, by manually holding the sound insulation cotton 311 to be installed, the mounting arc plate 306 fixed on the bottom surface of the sound insulation cotton 311 can be slid to the upper surface of the mounting box 303. At the same time, the mounting block 305 fixed on the bottom surface of the mounting arc plate 306 can be slid into the interior of the mounting box 303. Furthermore, the two wedge blocks 307 fixed on the bottom surface of the mounting arc plate 306 can be respectively engaged in the engagement grooves 304 opened on both sides of the mounting box 303. Since the wedge blocks 307 can be tilted along the direction close to the mounting block 305, the wedge structure of the wedge blocks 307 will engage in the engagement grooves 304, thereby making it easy to securely install the sound insulation cotton 311 into the interior of the tire body 1.

[0030] Then, the wheel hub 201 is manually installed into the tire body 1, and two retaining rings 202 are used to securely fasten the wheel hub 201 into the interior of the tire body 1. At the same time, the inflation tube 205, which is fixedly connected to the inside of the tire body 1, passes through the wheel hub 201, which makes it easy to inflate the tire body 1. The outer surface of the installed wheel hub 201 is in contact with the side of the multiple sound insulation cotton 311, and the mounting bracket 203 and the rotating shaft 204 can be used to install the silent tire in the required position.

[0031] The noise reduction function of the quiet tire is improved by fixing the wear-resistant strip 301 and the irregular tread groove 302 on the outer surface of the tire body 1. By repeating the above steps, the noise reduction airbag 310 and the sound insulation cotton 311 can be removed from the tire body 1 by manually squeezing the wedge block 307 in the locking groove 304. This makes it easy to disassemble and install the sound insulation structure inside the quiet tire, reduce the maintenance cost of the quiet tire, and facilitate the maintenance and use of the quiet tire.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
