Description

Technical Field

[0001] This utility model belongs to the field of automotive tire technology, specifically a self-healing noise-reducing tire. Background Technology

[0002] Self-sealing tires are a type of tire that achieves active sealing by coating the inner wall of the tire with a special polymer self-sealing coating. When punctured by a sharp object with a diameter of ≤6mm, the coating will instantly wrap the foreign object and stop the air leakage due to its excellent viscoelasticity and fluidity.

[0003] When a car is running at high speed, the tire surface vibrates due to the contact between the tire and the road surface, which is uneven. This vibration causes the air inside the tire cavity to vibrate and resonate, creating noise that is uncomfortable for the human body. Therefore, manufacturers will carry out noise reduction treatments on tires during production.

[0004] Existing technologies typically reduce noise by attaching sound-absorbing cotton to the inner wall of the tire. However, the sound-absorbing cotton is only bonded by an adhesive coating, and it may fall off when the tire is rotated. Therefore, a self-healing noise-reducing tire is proposed to address this problem. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a self-healing noise-reducing tire.

[0006] The technical solution adopted by this utility model to solve its technical problem is a self-healing noise reduction tire, including a tire body, a steel belt layer inside the tire body, a noise reduction component inside the tire body, and a self-healing component inside the tire body. The noise reduction component includes a washer fixedly installed on the inner wall of the tire body. The outer surface of the washer has an installation opening, and sound-absorbing cotton is installed inside the installation opening. A stop post is installed on the top of the sound-absorbing cotton.

[0007] Preferably, the interior of the mounting port is coated with an adhesive coating, and the top of the abutment is fixedly mounted on the top of the inner wall of the tire body.

[0008] Furthermore, the sound-absorbing cotton is installed on the outer surface of the gasket with a certain gap from the bottom of the inner wall of the tire body. However, the tire body is curved. When the tire body is installed on the car, the weight of the car is applied to the tire body, which will make the tire body become horizontal. As a result, the inner wall of the tire body will come into contact with the sound-absorbing cotton to reduce the noise generated by the tire body.

[0009] Preferably, multiple abutments are provided, and the multiple abutments are arranged in a circumferential array on the top of the inner wall of the tire body.

[0010] Preferably, the self-healing component includes a groove formed on the inner wall of the tire body, and the outside of the groove is provided with a self-healing coating.

[0011] Preferably, the self-healing coating is applied to the bottom of the inner wall of the tire body, and multiple grooves are provided, which are distributed in a circumferential array on the inner wall of the tire body.

[0012] Preferably, the outer surface of the tire body is provided with grooves. Further, multiple grooves are provided on the outer surface of the tire body, distributed in a circumferential array, and symmetrically distributed on both sides of the outer surface of the tire body to reduce airflow noise.

[0013] The beneficial effects of this utility model are: This invention uses a gasket to increase the thickness of the tire body's sidewalls, suppressing vibrations on the tire sidewalls and blocking noise transmission to reduce noise generated during tire operation. The sidewalls of the sound-absorbing cotton are then bonded to the outer surface of the gasket using an adhesive coating. Multiple abutments are arranged in a circumferential array and installed on the top of the tire body's inner wall, with the abutments resting precisely against the top of the sound-absorbing cotton. This abutments limit the sound-absorbing cotton on the gasket, allowing it to cover the bottom of the tire body's inner wall, forming a buffer layer to isolate noise and further reduce the noise generated by the tire body.

[0014] 2. In this invention, when the self-healing coating is applied to the inner wall of the tire body, the self-healing coating can enter the inside of the groove, and thus the self-healing coating can be more firmly applied and adhered to the inner wall of the tire body. The self-healing coating can wrap and seal the puncture hole of the tire body, effectively preventing the leakage of compressed air inside the tire. Attached Figure Description

[0017] 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 scope of protection of the present utility model.

[0018] Please see Figures 1-5 As shown, a self-healing noise-reducing tire includes a tire body 1, a steel belt layer 11 disposed inside the tire body 1, a noise-reducing component 2 disposed inside the tire body 1, and a self-healing component 3 disposed inside the tire body 1. The noise reduction component 2 includes a washer 201 fixedly installed on the inner wall of the tire body 1. The outer surface of the washer 201 has an installation port 202. The installation port 202 is filled with sound-absorbing cotton 203. The top of the sound-absorbing cotton 203 is fitted with a stop post 204.

[0019] Through the above technical solution, a steel wire bundle layer 11 is provided inside the tire body 1. The steel wire bundle layer 11 is a skeleton structure located inside the tire body 1. Through the rigid support and load transmission capacity of high-strength steel wire, the support force of the tire body 1 is increased. A washer 201 is installed on the bottom side of the inner wall of the tire body 1. The washer 201 can increase the thickness of the side of the tire body 1, suppress the vibration of the tire sidewall, and block the transmission of noise to reduce the noise generated by the tire body 1 during operation. The side of the sound-absorbing cotton 203 is adhered to the outer surface of the washer 201 through an adhesive coating, so that the sound-absorbing cotton 203 covers the bottom of the inner wall of the tire body 1, forming a buffer layer to isolate noise. The sound-absorbing cotton 203 is easily detached from the outer surface of the washer 201 due to the adhesive coating. Multiple abutments 204 are arranged in a circumferential array and installed on the top of the inner wall of the tire body 1. The abutments 204 of appropriate length are selected according to the thickness of the sound-absorbing cotton 203 so that the abutments 204 are exactly against the top of the sound-absorbing cotton 203. The abutments 204 are installed on the inner wall of the tire body 1 by heat fusion. In this way, the multiple abutments 204 can limit the sound-absorbing cotton 203 on the washer 201, thereby achieving the effect of limiting the installation of the sound-absorbing cotton 203 into the interior of the tire body 1.

[0020] It should be noted that the adhesive coating is preferably a butyl rubber-based adhesive, which can adhere the sound-absorbing cotton 203 to the outer surface of the gasket 201.

[0021] Considering the issue of how the tire body 1 can self-repair after being punctured, refer to... Figure 3 and Figure 5 The specific structure of the self-healing component 3 is disclosed. The self-healing component 3 includes a groove 301 opened on the inner wall of the tire body 1, and a self-healing coating 302 is provided on the outside of the groove 301.

[0022] The self-healing coating 302 is applied to the bottom of the inner wall of the tire body 1. Multiple grooves 301 are provided, and the multiple grooves 301 are arranged in a circumferential array on the inner wall of the tire body 1.

[0023] Through the above technical solution, multiple circumferentially arrayed grooves 301 are opened on the inner wall of the tire body 1. When the self-healing coating 302 is applied to the inner wall of the tire body 1, the self-healing coating 302 can enter the interior of the grooves 301, and thus the self-healing coating 302 can be more firmly applied and adhered to the inner wall of the tire body 1. When the tire body 1 is punctured by a sharp object, the self-healing coating 302 has unique viscoelasticity and fluidity, and will actively flow to the puncture opening at the moment of puncture, tightly wrapping the puncture opening to form a tough sealing layer, effectively preventing the leakage of compressed air inside the tire body 1.

[0024] It should be noted that self-healing coating 302 is a special polymer material coated on the inner wall of a tire. Its main components usually include butyl rubber, other polymers, and some functional additives. When a tire is punctured, it can flow into the puncture site to seal it.

[0025] Finally, see Figure 1 The outer surface of the tire body 1 is provided with grooves 4. Multiple grooves 4 are provided on the outer surface of the tire body 1. The grooves 4 extend from the center of the outer surface of the tire body 1 to the side of the tire body 1 and gradually enlarge the opening 301 of the grooves 4. Enlarging the opening 301 of the grooves 4 can make the airflow in the grooves 4 more dispersed, avoid the airflow from concentrating in the narrow opening 301 and generating large noise, and reduce the noise generated by the rotation of the tire body 1.

[0026] In summary, the working principle of this utility model is as follows: When installing and using the tire body 1, the washer 201 increases the thickness of the tire body 1's sidewalls, suppressing vibrations on the tire body 1's sidewalls and blocking noise transmission to reduce the noise generated by the tire body 1 during operation. The sidewalls of the sound-absorbing cotton 203 are adhered to the outer surface of the washer 201 through an adhesive coating, so that the sound-absorbing cotton 203 covers the bottom of the inner wall of the tire body 1, forming a buffer layer to isolate noise. Multiple abutments 204 are installed in a circumferential array on the top of the inner wall of the tire body 1. The abutments 204 of appropriate length are selected according to the thickness of the sound-absorbing cotton 203, so that the abutments 204 exactly abut against the top of the sound-absorbing cotton 203. The abutments 204 are installed to the tire body 1 by heat fusion. On the inner wall of the tire body 1, multiple abutments 204 can limit the sound-absorbing cotton 203 on the washer 201, thereby limiting the sound-absorbing cotton 203 to be installed inside the tire body 1. This allows the washer 201 and the sound-absorbing cotton 203 to reduce the noise of the tire body 1. The grooves 4 on the outer surface of the tire body 1 extend from the center of the outer surface of the tire body 1 to the side of the tire body 1, gradually widening the groove opening 301. Widening the groove opening 301 can make the airflow in the groove 4 more dispersed, avoiding the airflow from concentrating in the narrow groove opening 301 and generating greater noise, further reducing the noise generated by the rotation of the tire body 1. When the self-healing coating 302 is applied to the inner wall of the tire body 1, the self-healing coating 302 can enter the interior of the groove 301, and thus the self-healing coating 302 can be more firmly applied and adhered to the inner wall of the tire body 1. When the tire body 1 is punctured by a sharp object, the self-healing coating 302 has unique viscoelasticity and fluidity, and will actively flow to the puncture opening at the moment of puncture, tightly wrapping the puncture opening to form a tough sealing layer, effectively preventing the leakage of compressed air inside the tire.
