Description

Annular mute sponge strip attached to inner wall of tire

Technical Field

The utility model relates to the technical field of production of mute tires, in particular to an annular mute sponge strip adhered to the inner wall of a tire.

Background

Tire noise is generated by the friction of tires with the road surface when the vehicle is traveling at high speed. In order to reduce the tire noise, the existing solution is to attach a layer of mute sponge (sponge for short in this text) on the inner side wall of the tire. Normally, one side of the mute sponge strip facing the inner wall of the tire is flatly adhered to the inner wall of the tire through glue solution. While a tire to which a mute sponge is attached is also commonly referred to as a mute tire (herein simply referred to as a tire).

However, when the sponge strip is curled into a ring shape and fixedly attached to the inner wall of the tire, gaps are usually formed between the ends of the ring-shaped sponge strip, i.e. the length of the sponge strip is smaller than the inner circumference of the tire. The existence of the notch can lead the sponge strip not to be externally expanded towards the inner wall of the tire, so the sponge strip is only attached to the inner wall of the tire by means of glue solution. The gravity of the sponge strip can lead the sponge strip to have a tendency of separating from the inner wall of the tire, so that when the service time is longer, the sponge strip is easy to separate from the inner wall of the tire, and the service life of the mute tire can be reduced. Especially when the glue is not dried completely, the adhesive force of the glue is limited, and the gravity of the sponge strip can lead the sponge strip to be partially or completely separated from the inner wall of the tire, so that the attaching effect is poor or fails. In addition, the notch reduces the silencing effect of the tire.

Disclosure of Invention

The utility model aims to provide an annular mute sponge attached to the inner wall of a tire so as to solve the problems in the prior art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the annular mute sponge strip comprises a sponge strip curled into an annular shape, wherein the head and tail ends of the sponge strip are contacted with each other, the head and tail end faces of the sponge strip are adhered through double-sided adhesive tapes, the length of the sponge strip is longer than the inner circumference of the tire by-100-100 mm, and the annular sponge strip is adhered to the inner wall of the tire.

As a preferable technical scheme of the utility model, the annular sponge strip consists of 1-8 sponge sections, and the ends of the adjacent sponge sections are adhered by double-sided adhesive tapes.

As a preferable technical scheme of the utility model, the area of the double-sided adhesive tape occupies 50-100% of the area of the head end face and the tail end face of the sponge strip.

As a preferable technical scheme of the utility model, the thickness of the double-sided adhesive tape is 0.01-5mm.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, gaps between the ends of the sponge strips can be avoided by limiting the head-to-tail contact of the silence sponge strips curled into a ring shape, so that the silence effect can be improved; secondly, through limiting the head and the tail contact of the annular silence sponge strip of curling, the silence sponge strip of head and the tail contact can produce certain external tension, and this external tension is towards the tire inner wall, so silence sponge strip natural laminating on the tire inner wall, this external tension can offset the trend that makes silence sponge strip break away from the tire inner wall that gravity produced completely, even still has the balance, consequently can make silence sponge strip and tire inner wall's bonding force more firm, the sponge strip is difficult for droing, be favorable to prolonging silence tire's life. In addition, in the process of completely drying the glue, the external tension can enable the sponge strip to be clung to the inner side wall of the tire until the glue is thoroughly solidified, so that the attaching operation of the mute sponge strip is simpler and more convenient, and the attaching success rate and the attaching efficiency are higher.

Detailed Description

In order that those skilled in the art will better understand the present application, a clear and complete description of the technical solutions in the embodiments of the present application will be provided below, and it is apparent that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, based on the embodiments herein, which would be apparent to one of ordinary skill in the art without having made inventive work, are intended to be within the scope of the present application.

It should be noted that, without conflict, the embodiments and features in the embodiments may be combined with each other, and the present application will be described in detail with reference to the embodiments.

As shown in fig. 1-6, the embodiment provides an annular mute sponge strip attached to the inner wall of a tire, which comprises a sponge strip 1 curled into an annular shape, wherein the head and the tail of the sponge strip 1 are contacted, the head and the tail of the sponge strip 1 are adhered through a double-sided adhesive tape 2, and the length of the sponge strip 1 is 100-100mm longer than the inner circumference of the tire 3.

As shown in fig. 2, 3 and 7, the annular sponge strip may be composed of 1-8 sponge sections, and the ends of adjacent sponge sections are adhered by double-sided adhesive tapes.

Further, the area of the double-sided adhesive tape 2 accounts for 50-100% of the area of the head-tail overlapping area of the sponge strip 1.

Further, the thickness of the double-sided tape 2 is 0.01-5mm.

The working principle of the embodiment is as follows: according to the embodiment, gaps between the head and the tail of the sponge strip 1 can be avoided by limiting the head and the tail of the silence sponge strip 1 curled into the ring shape, so that the silence effect is improved; secondly, through limiting the head and the tail contact of the silence sponge strip 1 curled into the ring shape, the silence sponge strip 1 contacted from head to tail can produce certain external tension, and this external tension is towards the tire inner wall, so silence sponge strip 1 naturally laminates on tire 3 inner wall, and this external tension can offset the trend that makes silence sponge strip 1 break away from tire 3 inner wall that gravity produced completely, even still has the balance, therefore can make silence sponge strip 1 more firm with the adhesive force of tire 3 inner wall, silence sponge strip 1 is difficult for droing, is favorable to prolonging the life of silence tire 3. In addition, in the process of completely drying the glue, the external tension can enable the sponge strip 1 to be clung to the inner side wall of the tire until the glue is thoroughly solidified, so that the attaching operation of the mute sponge strip 1 is simpler and more convenient, and the attaching success rate and the attaching efficiency are higher.

The area of the double-sided adhesive tape 2 is limited to be 50-100% of the area of the head-to-tail overlapping area of the sponge strip 1, so that the usage amount of the double-sided adhesive tape 2 can be reduced on the basis of ensuring the head-to-tail connection firmness of the sponge strip 1; the thickness of the double-sided adhesive tape is limited to be 0.01-5mm in the same way, so that the weight of the double-sided adhesive tape 2 can be effectively reduced, and the sponge strip is not easy to fall off from the tire.
