Such resonance noise is often transmitted to the inside of the vehicle, and the resonance noise may cause the driver or the occupant to feel uncomfortable and fatigue may be increased.

Accordingly, a method for reducing such resonance noise has been studied, and a method of processing a material such as a polyurethane foam having a sound absorbing performance into a cavity inside a tire, or attaching the material to the inner surface of the rim surface or the inner liner inside the tread portion And a tire equipped with such a sound absorbing body is referred to as a low noise tire.

As shown in Fig. 1, a conventional low-noise tire has a structure in which a sound-absorbing material is attached to an inner liner inside a tread, and a sound-absorbing material is attached to the inner liner inside the tread using a double-sided tape. The use of double-sided tape in this way has advantages in that the working process is clean and the working time is short. However, the double-sided tape does not adhere well at the initial stage of attaching the double-sided tape to the absorbent article, There is a drawback that the tape falls off.

Accordingly, spray adhesives are applied to the inside of the pores of the tire to adhere the sound absorbers. However, the use of the spray adhesives as environmentally hazardous materials is limited, and it is difficult to use the spray adhesives in the mass production line due to the risk .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a sound absorbing body fixing device for a low noise tire according to the present invention will be described with reference to the accompanying drawings.

The sound absorbing body fixture for a low noise tire according to the present invention fixes the sound absorbing body 30 in a low noise tire in which the sound absorbing body 30 is fixed to the inner liner 21 inside the tread portion 21, A pair of elastic rings 11 having a diameter larger by about 2 to 4% than the inner diameter of the sound absorbing body 21 and being elastically deformed by an external force and arranged at a larger interval than the width of the sound absorbing body 30; Both ends of the sound absorbing body 30 are connected to the elastic rings 11 so as to cross the upper surface of the sound absorbing body 30 to press the sound absorbing bodies 30 and are disposed at regular intervals along the circumferential direction of the elastic rings 11 And a plurality of support members (12).

Here, it is preferable that the support member 12 has a shape corresponding to the contour of the scratch-resistant body 30. That is, by forming the support member 12 in a shape corresponding to the upper structure of the sound-sensitive body 30, the support member 12 is firmly adhered to the upper portion of the sound-

Further, the support member 12 may be formed in a network structure. This is to enable the support member 12 to firmly support the sound absorbing body 30 without affecting the performance of the sound absorbing body 30.

On the other hand, the elastic ring 11 is preferably formed of high carbon steel or high elasticity plastic, but is not limited to these materials. Since the elastic ring 11 requires a high elastic force, high carbon steel or highly elastic plastic having excellent elasticity and low weight is used. In order to reduce the weight of the elastic ring 11, it is more preferable that the elastic ring 11 has a hollow structure. The reason for reducing the weight of the elastic ring 11 as described above is that the larger the weight of the elastic ring 11, the worse the fuel consumption is.

The sound absorbing body fixture of the low noise tire of the present invention constituted as described above is fixed by using the elasticity of the elastic ring without attaching the sound absorbing body to the inner liner of the tire.

The sound absorbing body 30 is positioned inside the inner liner 22 inside the tread portion 21 of the tire so that the elastic rings 11 are positioned on both sides of the sound absorbing body 30, The support member 12 whose both ends are connected to the elastic ring 11 is brought into close contact with the sound absorbing body 30 from above the sound absorbing body 30 when the fixture 10 is inserted. The sound absorbing body 30 is fixed without moving.

That is, since the diameter of the elastic ring 11 is larger than the inner diameter of the inner liner 22, the elastic ring 11 is strongly adhered to the inner surface of the inner liner 22, Tightly presses the upper surface of the sound absorbing body 30, so that the sound absorbing body 30 is fixed.

If the support member 12 does not strongly press the sound absorbing body 30, the support member 12 can strongly press the sound absorbing body 30 by widening the interval between the elastic rings 11 have.

As described above, the sound absorbing body fixture 10 of the present invention fixes the sound absorbing body 30 using the elastic force of the elastic ring 11. Accordingly, the sound absorbing body fixing member 10 and the sound absorbing body 30 of the present invention can be supplied to a dealer or the like as a single unit, so that a consumer can use the sound absorbing body 30 as a low noise tire by installing the sound absorbing body 30 in a general tire.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated by those of ordinary skill in the art that numerous changes and modifications can be made to the invention without departing from the spirit and scope of the invention.
