Tire with low cavity noise and processing device therefor

Abstract

A tire with low cavity noise, the tire comprising: a tire (1) having a cavity noise reduction device; a silencing element (2); and an adhesive (3), wherein the silencing element (2) is in the shape of a long strip, and is helically attached to the inner wall of the tire (1) by means of the adhesive (3). Further disclosed is a tire processing device. The aim of increasing the contact area between the silencing element and the air inside the tire can be achieved by controlling the spacing width between two sections of the silencing element and the thickness of the silencing element; as the silencing element is prepared in the shape of a long strip and is entirely wound around and attached to the inner wall of the tire, the silencing element has only two end points on the inner wall of the tire, thus reducing the risk of conventional tires with low cavity noise being damaged due to having a large number of end points; in addition, as the width of the silencing element is reduced compared with the width of silencing elements in conventional tires with low cavity noise, the stress concentration at the end points is reduced, and the damage risk at the end points is further reduced.

Description

A tire with low cavity noise and a processing device thereof Technical Field

[0001] The present invention relates to the technical field of tire processing, in particular to a tire with low cavity noise and a processing device thereof. Background Art

[0002] Typically, when a vehicle is traveling at high speed, the tires generate a lot of noise when they come into contact with road irregularities or are impacted by external forces. This noise propagates within the tire, causing the air inside to vibrate through the tire itself. This noise acts as a sound amplifier, amplifying the noise. This noise is called tire cavity noise, and it is one of the most important factors affecting driver and passenger comfort. A more mature technology currently available involves applying highly foamed, silent elements to the inner wall of the tire. This changes the volume and shape of the tire cavity, disrupting air circulation and reducing the resonance of sound waves propagating within the tire cavity, thereby reducing tire cavity noise.

[0003] Currently, all tires sold on the market have highly foamed silent elements applied to the tire's inner wall. This changes the volume and shape of the tire's inner cavity, thereby achieving the purpose of air disturbance, reducing the resonance of sound waves propagating within the tire cavity, lowering noise peaks, and thus reducing tire cavity noise. Typically, such silent elements are applied to the tire's inner wall in one or more sections. The width, thickness, and number of sections of the silent element determine the contact area between the silent element and the air in the tire's inner cavity. Generally, when the width and thickness of the silent element are the same, the more sections there are, the greater the contact area between the silent element and the air in the tire's inner cavity, the more significant the absorption and air disturbance effect on sound waves, and thus the better the effect of reducing tire cavity noise.

[0004] When a vehicle is traveling at high speed, the tire will be subjected to impact force from the ground during the high-speed rotation process. This impact force and the air resistance inside the tire will generate stress on the silent element, causing the silent element to age faster and reduce fatigue life. Usually, the front and rear ends of the silent element are more prone to damage such as tortuosity, cracks, and warping. Increasing the number of segments of the silent element will produce more front and rear endpoints, and the risk of damage to the silent element will also increase with the increase in the number of segments.

They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0034] The present invention provides the following embodiments Example 1

[0035] An embodiment of the present invention provides a low-cavity noise tire and a processing device thereof, as shown in Figures 1-9. The tire includes a cavity noise reduction device consisting of a tire 1, a silent element (2), and an adhesive rubber 3. The silent element 2 is in the shape of a long strip and is adhered to the inner wall of the tire 1 in a spiral manner through the adhesive rubber 3.

[0036] Preferably, the silent element 2 is a polyurethane foam element, and the cross section of the silent element 2 is any one of rectangular, trapezoidal, and semicircular.

[0037] Preferably, the thickness H of the silent element 2 is in the range of 10 mm ≤ H ≤ 50 mm; the width W1 of the silent element 2 is in the range of 15 mm ≤ W ≤ 150 mm, and H ≤ W1.

[0038] Preferably, the silent element 2 is adhered to the inner wall of the tire 1 in a spiral manner with the axis of the tire 1 as the axis, and the interval between adjacent spiral turns of the silent element 2 is d; 3mm≤d≤30mm, and d≤2H.

[0039] The working principle and beneficial effects of the above technical solution are as follows: by reducing the width of the conventional silent element 2 and preparing it into a long strip, the entire strip is applied to the inner wall of the tire in a spiral manner. In the transverse direction (tire width direction) of the tire, the spacing between the two circles of silent elements 2 increases the contact area between the silent element 2 and the air inside the tire. In the radial direction (tire height direction), the two additional side surfaces on the left and right sides of the silent element 2 increase the contact area between the silent element 2 and the air inside the tire and in the thickness direction of the silent element 2. The present invention achieves the purpose of increasing the contact area between the silent element 2 and the air inside the tire by controlling the width of the spacing between the two sections of silent element 2 and the thickness of the silent element 2.

[0040] At the same time, because the silent element 2 is prepared in a long strip shape and the entire strip is wrapped and applied to the inner wall of the tire, the silent element 2 has only two endpoints in the inner wall of the tire, reducing the damage risk caused by the large number of endpoints in traditional low-altitude noise tires. In addition, because the width of the silent element 2 of the present invention is smaller than that of traditional low-altitude noise tires, stress concentration at the endpoints is reduced, further reducing the risk of damage at the endpoints.

[0041] H≤W1 can ensure the stability of the silent element 2 during the pasting process and reduce the difficulty of pasting; 3mm≤d≤30mm. If the interval d is designed to be too small, due to the curvature of the inner wall of the tire, the silent element 2 will easily come into contact with adjacent spiral coils after spiral pasting. If the interval d is designed to be too large, the contact area between the silent element 2 and the air inside the tire will be reduced. At the same time, if the interval d is designed to be too large, the number of pasting coils of the silent element 2 will be reduced, so that the total length of the silent element 2 is reduced, the contact area between the silent element 2 and the air inside the tire is reduced, and the noise reduction effect of the tire is reduced. Example 2

[0042] Based on Example 1, the overall width of the noise-reducing element 2 formed on the inner wall of the tire 1 is W, 60 mm ≤ W ≤ 300 mm, W ≤ the belt width of the tire 1 - 40 mm;

[0043] In a 235 / 45R18 tire, the width W is designed to be 165 mm. The number of laps of the silent element 2 is 4.

[0044] The working principle and beneficial effects of the above technical solution are as follows: Here, if the width W is designed to be too wide, the silent element 2 is likely to be attached to the tire shoulder area, that is, the transition area between the tire tread and the sidewall. The transition curvature here is large, making it more difficult to attach the silent element 2. In addition, during use, the sidewall is deformed due to ground impact, making the silent element 2 more likely to fall off.

[0045] Theoretically, the more turns N of the silent element 2, the better the noise reduction effect. Here, the number of turns of the silent element 2 is determined by the tire specifications, the inner wall width of the tire, the width W1 of the silent element 2, and the spacing d of the silent element 2. For tires of the same specifications, the more turns N of the silent element 2, the smaller the width W1 of the silent element 2 and the spacing d of the silent element 2 need to be designed. However, a small width W1 of the silent element 2 may easily lead to a decrease in the overall strength of the silent element 2, thereby reducing its service life. If the spacing d of the silent element 2 is designed to be too small, after the silent element 2 is spirally applied, adjacent spiral turns may easily come into contact, thereby reducing the noise reduction effect. Here, the overall width W=N*W1+(N-1)*d, and W≤tire 1 belt layer width-40mm. Example 3

[0047] The working principle and beneficial effects of the above technical solution are as follows: during operation, the tire mounting assembly sends the tire 1 to the processing area, that is, directly in front of the silent element covering assembly, waiting to be processed. At the same time, the silent element 2 is cleaned and glued by the feeding assembly and output to the silent element covering assembly. After that, the silent element covering assembly carries the silent element forward and covers the silent element on the silent element covering assembly on the inner wall of the tire 1. Example 4

[0050] The working principle and beneficial effects of the above technical solution are as follows: when working, the power supply box 4000 drives the adjusting roller body 1 4007, the adjusting roller body 2 4008, the transition roller 1 4003 and the transition roller 2 4004 to rotate, and the silent element 2 on the silent element cylinder 4009 starts from the silent element cylinder 4009 and passes through the fixed cleaning roller 402 and the movable cleaning roller 4020, the adjusting roller body 1 4007, the adjusting roller body 2 4008, the transition roller 1 4003 and the transition roller 2 4004 in sequence, and is output to the silent element covering component, wherein when between the fixed cleaning roller 402 and the movable cleaning roller 4020, the fixed cleaning roller 402 and the movable cleaning roller 4020 can clean the surface of the silent element 2, and the fixed cleaning roller The distance between the movable cleaning roller 4020 and the fixed cleaning roller 4020 is adjustable.
