Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following embodiments.

In the description of the present invention, it should be noted that, unless otherwise explicitly stated or limited, the terms "connected," "mounted," and "fixed" are to be construed broadly, and those skilled in the art can understand the specific meaning of the above terms in the present invention in a specific manner.

As shown in fig. 1 to 3, the pneumatic tire with compensation function includes a tire body a. As shown in the figure, the tire body a is a conventional tire, and comprises a rim 1 and a rubber tire casing 2 mounted on the rim 1. Rubber tire casing 2 wholly is the annular, and rim 1 is the annular, rubber tire casing 2 direct mount is on rim 1, and concrete connection lies in: as shown in fig. 1, the rubber tire casing 2 has a C-shaped cross section, and includes a crown portion 21 in the middle and side portions 22 on both sides, the crown portion 21 and the side portions 22 on both sides are integrally formed, and the lower ends of the side portions 22 on both sides are directly fixed to the rim 1. The rubber tyre shell 2 and the rim 1 form a closed space, so that the inflation is convenient. The crown 21 can be provided with the concave-convex structure 20 to achieve the anti-skid effect.

In order to achieve the compensation function of the tire, a supporting framework 3 is arranged inside the rubber tire shell 2. As shown in fig. 1-2, the support frame 3 is annular in shape, and the support frame 3 is directly mounted on the rim. Specifically, the supporting framework 3 has an approximately square cross section, and includes an arc top 31, two side surfaces 32 connected to the arc top 31, and a bottom 33. The bottom portion 33 is closely attached to the rim 1. The radius of the supporting framework is 2/3 that of the rubber tyre casing 2 for the subsequent air bag 4. The support frame divides the overall tire into an inner chamber a1 and an outer chamber a 2. Preferably, the volume of the inner cavity a1 is 60%, the volume of the outer cavity a2 is 40%, the supporting effect of the inner cavity a1 can be ensured, and when the outer cavity a2 is broken, the inner cavity a1 is quickly filled in the rubber tire casing 2.

To achieve release of the bladder 4 from the support frame 3, a tear seam 30 is provided in the support frame 3, the tear seam 30 being disposed at the top of the arcuate apex 31 as shown in the cross-section of fig. 1. The whole structure of the air bag 4 is also annular and is directly arranged in the supporting framework 3, the section of the air bag 4 is C-shaped, and the air bag 4 is tightly attached to the inner surface of the supporting framework 3. Furthermore, in order to ensure the air tightness of the air bag 4, the left and right opening ends of the air bag 4 are adhered to the left and right side surfaces of the supporting framework 3. The actual radius of the bladder 4 in this embodiment corresponds to the inner radius of the rubber tyre casing 2, which results in a fold 41 of the bladder 4 which facilitates the close fitting of the bladder 4 within the support frame 3. The present embodiment preferably has two folds, one on each of the left and right sides of the tear seam 30.

The support framework 3 in the embodiment is made of flexible materials, and can be a carbon fiber framework. In order to facilitate the inflation of the air bag 4, the present embodiment is provided with an inflation valve 5, the inflation valve 5 is fixed on the rim 1, and the inflation valve 5 penetrates through the rim 1 and the support framework 2 and is communicated with the air bag 4. The inflation valve 5 inflates the airbag 4 by an auxiliary inflation device.

In use of this embodiment, when the tire a is first used, both the inner chamber a1 and the outer chamber a2 are inflated, and when the pressure of the inner chamber a1 is higher than the pressure of the outer chamber a2, particularly when the pressure of the inner chamber a1 is 1.2 times the pressure of the outer chamber a2, the inflation is stopped. This operation ensures that the inner chamber a1 is subjected to a relatively small impact force when the outer chamber a2 is compressed during use.

When the crown portion 21 of the rubber tire housing 2 is punctured or cracked, the outer cavity a2 leaks air instantly, but the vehicle does not have serious unbalance to cause accidents due to the existence of the inner cavity a 1. The inflation pressure of the inner cavity a1 is increased sharply by inflating the inflation valve 5, when a certain pressure is reached, the inner cavity a1 is burst from the rupture seam 30, the air bag 4 is filled in the whole rubber tire casing 2, and the broken support framework 3 is extruded by the air bag 4 to the inner surface of the rubber tire casing 2, so that the support function is realized on one hand, and the protection function is also realized on the other hand. Furthermore, when the supporting frame 3 is just pressed on the inner surface of the rubber tire housing 2 to block the crack or the needle puncture portion as shown in fig. 3, the supporting frame 3 acts as a barrier to the damage of the air bag 4 or the needle puncture, thereby avoiding the problem that the whole tire is subjected to secondary tire burst.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
