A plurality of support rings 20 are each independently installed so as to be detachably attached to the inside of the tire 2 so as to be supported inside the tire 2. The support ring 20 can be easily fixed to the annular ring 22 formed with a diameter capable of accurately supporting the tread 4 and the shoulder 6 and the tread 4 and the shoulder 6. It is made by forming the ring mounting bolt 24 so as to protrude on the outer circumferential surface of one side of the annular ring 22.

In addition, the support ring 20 may be formed by changing into a ring shape of various shapes according to a design in addition to a circular shape.

In addition, the support ring 20 is screwed to the fastening hole 32 for the tread formed in the inside of the tread 4 and the shoulder 6 and the fastening hole 34 for the shoulder. Accordingly, the support ring 20 can be simply replaced when damaged or damaged.

And the support ring 20, a large diameter support ring (20a) coupled to the tread fastening hole 32 to support the tread (4) with a ring mounting bolt (24), and shoulders (6) on both sides It is composed of a small diameter support ring (20b) coupled to the ring mounting bolt 24 to the fastening hole for the shoulder 34 to support the. That is, the support ring 20 can be installed in a diameter size suitable for the installation position inside the tire 2, so that it is possible to appropriately respond to the load pressure acting on the tire.

In addition, the support ring 20 is formed of an elastic body so that restoration of elastic force can be quickly achieved in response to a load pressure acting on the left and right sides of the tread 4 and the tire 2. The support ring 20 formed of an elastic body supports while receiving the maximum pressure when receiving a load pressure, and elastic force is exerted at the time when the load pressure is released to quickly restore the deformation of the tire.

In addition, the small-diameter support ring 20b is formed to have a diameter such that a portion of the inner curved surface formed over the shoulder 6 and the side wall 8 can closely adhere. That is, when the small diameter support ring 20b is installed in close contact with the shoulder 6, the pressure applied in the left-right direction of the tire 2 is firmly supported.

Formed at regular intervals along the center line CL formed on the tread 4 along the circumferential direction of the tire 2 so as to correspond accurately, the fastener 34 for the shoulder is also left right of the tire 2 It is formed at regular intervals along the side line SL drawn along the circumferential direction on the shoulder 6 so that the small diameter support ring 20b can accurately correspond to the load pressure acting in the direction.

In the fastening hole 32 for the tread and the fastening hole 34 for the shoulder, as shown in Fig. 1 or 3, the screws of the ring mounting bolt 24 in the tread 4 and the shoulder 6 A bolted fastening pipe 40 having a buried support 40a is buried so that the coupling can be maintained firmly.

Hereinafter, an installation example and an operation example of the present invention made as described above will be described in detail with reference to the drawings.

First, when the installation example of the detachable type support ring is described, as shown in FIG. 1, the fastening hole 32 for the tread formed on the tread 4 and both shoulders 6 and the fastening hole 34 for the shoulders are provided. The support ring 20 is engaged. That is, a large diameter support ring 20a is coupled to and installed in the fastening hole 32 for tread, and a small diameter support ring 20b is coupled to and installed in the fastener 34 for shoulder. Further, depending on the design selection, the fastening hole 32 for the tread and the fastening hole 34 for the shoulder may have a fastening tube 40 for fastening a bolt formed with a buried support 40a in advance.

In addition, a ring mounting bolt 24 coupled to the fastening hole 32 for the tread and the fastening hole 34 for the shoulder may optionally have a close contact support 24a formed according to design needs. And, as shown in Figs. 1 to 5, the support ring 20 is provided solely for each fastening hole 32 for the tread and the fastening hole 34 for the shoulder. Therefore, during the driving between the large diameter support ring 20a and the small diameter support ring 20b constituting the support ring ring 20, the load pressure applied to the tire is supported without interference with each other. Accordingly, when the run flat tire 2 is repaired, for example, because it is a detachable type, only the damaged or damaged support ring 20 needs to be simply replaced, thereby reducing management costs.

In addition, among the support rings 20, the large-diameter support rings 20a, as shown in Fig. 4(a)(b), are installed to be in a linear posture like a '1' with respect to the circumferential direction of the tire 2 Can. That is, by allowing the installation position of the large-diameter support ring 20a to be diversified, it is possible to appropriately cope with the load pressure applied to the tread 4 and the tire 2 in various directions.

On the other hand, when explaining an example of the operation of the support ring 20, a puncture occurs in the run flat tire 2 while driving, and the air pressure of the tire is reduced. Accordingly, in the run flat tire 2, the tread 4 in contact with the ground receives the load pressure of the vehicle, but supports the load pressure by the support ring 20 inside the tire. That is, among the support rings 20, the large-diameter support ring 20a supports the tread 4, and the small-diameter support ring 20b supports both shoulders 6 so that the side wall 8 is excessively deformed. This prevents the tire from being damaged.

When the support ring 20 is subjected to the pressure of the load of the vehicle, the support ring 20 formed of an elastic body absorbs pressure while being deformed at least, and when the portion subjected to the load pressure changes, the elastic force of the elastic body is restored and the tread 4 is restored. And supporting the shoulder 6 as if pushing it out, so that the shape of the tire is maintained.

As described above, the support ring 20 is disposed at regular intervals along the circumferential direction of the tire to safely move the tire 2 in the puncture state from the inside of the run flat tire 2 to a place where it can be maintained while driving. To maintain the durability of the tire within a certain driving distance.
