Technical Field

The utility model relates to the technical field of tires, in particular to a run-flat automobile wheel and an automobile.

Background

The automotive industry has previously provided spare tires for replacing tires that have punctured or ruptured during driving. Efforts have been made to eliminate the need for a spare tire by improving the design of the tire. In particular, efforts have been made to provide a stable and economical tire capable of running with little or no pressure (e.g., a deflated tire). This work is known as the "run-flat" (RFT) technique. The RFT concept allows the driver to continue driving or driving for an extended period of time without having to stop for a tire change or seek emergency assistance, and the tire can be repaired at a later more convenient time.

The prior art of run-flat provides a support between the inner surface of the tire and the outer circumferential surface of the rim that allows the tire to be offset by a limited amount so that the tire does not separate from the rim along each edge of the tire, which places severe demands on the strength of the support, which is costly and complex to manufacture.

Example 1

The vehicle wheel usually comprises a tire and a rim for supporting the tire, and a cavity formed by the tire and the rim is filled with air so as to ensure that the tire pressure is normal and the vehicle can normally run. When the tire leaks, if the tire is punctured by a sharp object, the tire pressure is reduced, and the tire needs to be repaired in time in order to ensure the driving safety. When the automobile is in the long way, the automobile cannot find a repair shop to repair the tire in time, and a driver needs to replace the spare tire by self operation, so that the automobile is strenuous and is difficult to operate.

The present invention provides a run-flat automobile wheel, as shown in fig. 1, comprising a wheel body 100, wherein the wheel body 100 comprises:

a tire 10 for supporting an automobile body;

a rim 20 for supporting the tire 10; the tire 10 is mounted on the outer peripheral side of the rim 20; the tire 10 and the rim 20 are clamped together to form an air cavity 30 for storing air;

a plurality of air bags 40 for storing air are arranged in the air cavity 30; when the tire 10 is deflated, the air bag 40 supports the tire; when the tire 10 together with at least one air bag 40 is broken and deflated, the rest of the air bags 40 support the tire. Specifically, an air bag 40 is provided in an air chamber 30 formed by the tire 10 and the rim 20, the air bag 40 is inflated to make the air bag 40 in an inflated state, and the air chamber 30 is inflated to ensure the supporting force of the tire 10. When the tire 10 leaks air and all the air bags 40 are not damaged, the air in the space between the air cavity 30 and the air bags 40 slowly escapes out of the tire 10 along with the prolonging of time, the air pressure of the tire 10 is slightly reduced, and on one hand, the air leakage speed of the tire 10 is delayed because part of the air is stored in the air bags 40; on the other hand, due to the supporting function of the air bags 40 on the tire 10, the wheel body 100 can still work normally, so that the service life of the tire 10 in a deflated state is prolonged, enough time is provided for a user to find a repair shop along the way, and the user does not need to change the spare tire by himself. When the tire 10 is punctured by a sharp object, the air bag 40 is punctured, so that the air bag 40 is also damaged and starts to leak, and at the time, the air escaping from the tire 10 comprises two conditions, namely, the air in the space between the air cavity 30 and the air bag 40 slowly escapes from the tire 10, and the air in the air bag 40 slowly leaks into the space between the air cavity 30 and the air bag 40 and then slowly escapes from the tire 10. The arrangement of the air bags 40 can delay the air leakage speed of the tire 10 under two air leakage conditions, and can support the tire 10 by the rest of the air bags 40 to prevent the tire from being flat, thereby prolonging the safe driving time of the tire 10 in the air leakage state.

In one embodiment, the material of the air bag 40 is preferably low density polyethylene, which is waterproof, moisture-proof, non-toxic and has good barrier properties.

In one embodiment, the airbag 40 is an inflatable airbag 40, and the airbag 40 can be inflated periodically to ensure the inflation degree of the airbag 40. In another embodiment, the airbag 40 is a non-inflatable airbag 40, and the replacement of the airbag 40 is performed periodically, which is relatively expensive.

In one embodiment, the plurality of air pockets 40 are arranged in an annular array. The air cavity 30 formed by the tire 10 and the rim 20 is annular, and the plurality of air bags 40 are uniformly distributed along the extending direction of the air cavity 30 so as to uniformly support each part of the tire 10 by the plurality of air bags 40.

In one embodiment, the air bag 40 is a gas column bag, which has good cushioning and supporting properties.

In one embodiment, the air pockets 40 are spherical or cylindrical. When the air bag 40 is spherical, the surface of each portion of the air bag 40 is curved, and is not easily damaged when it is pressed by the inner surface of the tire 10 or the surface of the rim 20. When the air bag 40 is cylindrical, two bottom surfaces of the air bag 40 are respectively opposite to the inner surface of the tire 10 and the surface of the rim 20, and the two bottom surfaces are flat surfaces, so that the air bag 40 is not easy to damage when being pressed by the inner surface of the tire 10 or the surface of the rim 20; the side surfaces of the air bags 40 are curved surfaces, and when the adjacent air bags 40 are designed to be close to each other, the opposite surfaces of the adjacent air bags 40 have no sharp angle, so that the abrasion between the adjacent air bags 40 is avoided.

In one embodiment, two adjacent air bags 40 are engaged (not shown) so that all the air bags 40 in the air cavity 30 form an integral support structure, thereby increasing the support strength of the tire 10 by all the air bags 40. When one or some of the air bags 40 are damaged, the two intact adjacent air bags 40 can still be connected together, and a certain supporting force is ensured.

In one embodiment, the air bag 40 is removably attached to the surface of the rim 20. The air bag 40 is fixed by the surface of the rim 20, and the air bag 40 is limited to be located at a set position, so that the air bag 40 is prevented from being displaced in the air cavity 30 along with the rotation of the wheel body 100, and the air pressure balance of each part in the air cavity 30 is influenced, and certain driving danger is caused. In one embodiment, after the tire body 100 is assembled, before the space between the air chamber 30 and the air bag 40 is inflated, two ends of the air bag 40 respectively abut against the inner surface of the tire 10 and the surface of the rim 20; when the space between the air cavity 30 and the air bag 40 is inflated, the air bag 40 is pressed to a certain extent due to the increase of the air pressure of the space where the air bag 40 is located, the volume of the air bag 40 is reduced, one end of the air bag 40 is adhered to the surface of the rim 20 through the adhering part 21, and the other end of the air bag 40 is separated from the abutting of the inner surface of the tire 10. When the tire 10 punctures the air leakage, the air bag 40 slightly increases in volume as the air pressure in the air chamber 30 decreases to support the tire 10.

Further, the tire 10 and the rim 20 are respectively provided with a repeatedly adhesive part 21 for adhering the two ends of the air bag 40. Fixing the air bag 40 by adhering the two ends of the air bag 40 to the tire 10 and the rim 20 respectively, and when the air bag 40 is damaged, separating the two ends of the damaged air bag 40, adhering the adhering part 21, and removing the damaged air bag 40; in addition, a new air bag 40 can be bonded due to the repeatable bonding performance of the bonding portion 21. When the tire 10 is repaired, the damaged air bags 40 are replaced in time, a plurality of air bags 40 are distributed, and all the air bags 40 and the air in the air cavity 30 form a stable supporting structure for the tire 10. Specifically, the adhesive portion 21 may be a sticky tape, and the adhesive portion 21 may be removed from the rim 20 under a certain external force. For example, when the user opens the air bag for a long period of time and can remove and bond the bonding portion 21, all the air bags 40 are taken out, and the wheel body 100 is of a conventional wheel structure, so that the maintenance cost of the air bags 40 is reduced; when the user needs to drive a long distance, the air bag 40 is attached after the upper and bonding portions 21 are attached.

In one embodiment, as shown in FIG. 2, the air bag 40 has a plurality of air reservoirs 41. When a partial surface of the air bag 40 at a certain position of the air cavity 30 is punctured, the air storage chamber 41 corresponding to the surface is leaked, and other independent air storage chambers 41 of the air bag 40 are still sealed spaces. When the air in the air storage chamber 41 of the air bag 40 is leaked out slowly, the rest air storage chambers 41 of the air bag 40 still have a certain space supporting function so as to reduce the degree of the surface of the tire 10 corresponding to the part of the air cavity 30 being deflated. Namely, the air bag 40 is provided with a plurality of mutually independent air storage chambers 41, one air storage chamber 41 is deflated to a flat state, and the other air storage chambers 41 still enable the air bag 40 to have a certain expansion degree so as to prevent the air bag 40 or some air bags 40 from being gradually deflated to be completely flat when being punctured, and the driving danger is increased without any supporting force on the tire 10 at the part.

Further, a plurality of the air reservoirs 41 are arranged in a radial direction of the wheel body 100. When the tire 10 is punctured normally, a sharp object penetrates the tire 10 from the outer surface of the tire 10 toward the air chamber 30, and since the plurality of air reservoirs 41 are arranged in the radial direction of the wheel body 100, the air reservoir 41 arranged adjacent to the tire 10 is punctured to cause air leakage, and the remaining air reservoirs 41 of the air bag 40 are left in an inflated state and arranged in the radial direction of the wheel body 100 to support the vehicle between the inner surface of the tire 10 and the surface of the rim 20.

Example 2

The utility model provides an automobile comprising a run-flat automobile wheel as described above. In order to ensure the driving safety, the automobile wheel with the air leakage protection function is applied to all four wheels. The wheel body 100 reduces the speed of the tire 10 when leaking air, reduces the speed of the tire 10 when collapsing, improves the driving safety, provides enough time for users to find a repair shop along the way, and the users do not need to replace spare tires with great effort by themselves by arranging the air bag 40 in the air cavity 30.

The foregoing is merely a preferred embodiment of the utility model and is not intended to limit the utility model in any manner; those skilled in the art can readily practice the utility model as shown and described in the drawings and detailed description herein; however, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the scope of the utility model as defined by the appended claims; meanwhile, any changes, modifications, and evolutions of the equivalent changes of the above embodiments according to the actual techniques of the present invention are still within the protection scope of the technical solution of the present invention.
