Description

[0001] TIRE INCLUDING DETACHABLE AIR CHAMBER [0002]

The present invention relates to a tire comprising a detachable air chamber.

The tire has a function of supporting the entire load of the vehicle, a power transmission function of transmitting the driving force and the braking force of the vehicle to the road surface, a shock absorbing function of absorbing and alleviating the external impact from the irregular road surface, Position switching function, and the like.

Accordingly, if the tire is punctured, the tire can not be driven any more, and the tire air pressure is reduced instantaneously.

If you continue driving with a flat tire, it may cause damage to the wheel and suspension. In order to solve the problem of the tire puncture, a run flat tire capable of traveling a certain distance while supporting the load of the vehicle even in a state where the tire is punctured has been proposed.

Run-flat tires are suitable for drivers who frequently travel long distances, or for drivers who are not capable of replacing spare tires, especially female drivers. The conventional run flat tire enhances the strength of the sidewall so that the outer shape of the tire can be kept unchanged even if the tire air pressure is reduced due to air leakage.

However, such a conventional run flat tire has a problem in that the side wall side that absorbs and alleviates the external impact through the bending motion is formed of the solid member, so that the rigidity is more than necessary and the ride feeling is lowered.

In addition, a large amount of rubber is used to lower the fuel consumption characteristic, and there is a problem that the balance between the right and left sides of the tire is adversely affected.

Further, when the tire continues to run in the punctured state, severe compression and recovery occur repeatedly on the side of the side wall supporting the vehicle load, and the temperature locally rises rapidly. As described above, when the ambient temperature of the solid member rises due to the repetitive bending motion of the sidewall during the running of the tire, the joint portion with the inner liner and the carcass is separated and can lead to an accident. However, the maintenance method at this time had to replace the entire tire like the existing pneumatic tire.

The inner ring 10 is positioned at the center and performs the same function as a wheel that transmits the driving force of the vehicle to the tire 1. [ Further, since it carries the function of transmitting the driving force and the braking force of the vehicle to the road surface, it can be made of a plastic material satisfying the conditions of low weight and high strength. For example, PEEK (polyaryletherketone) .

A plurality of spokes (20) are formed at predetermined intervals along the outer peripheral surface of the inner ring (10). The spokes 20 may be formed of a plurality of plates formed in the shape of partitions along the outer circumferential surface of the inner ring 10 and the air chambers 30 And guide grooves 24 for fixing the position thereof can be formed.

In the present embodiment, eight spokes 20 are formed along the outer peripheral surface of the inner ring 10, but the spirit of the present invention is not limited thereto. The number of the spokes 20 can be freely modified It is possible.

The air chamber 30 may have a fan-shaped cross section and may include a tread 32 forming the outer surface of the tire 1, an inner wall 36 abutting the inner ring 10, And a sidewall 34 connecting the inner wall 36 with the sidewall 34. In addition, a hollow 38 is formed therein which is surrounded by the tread 32, the inner wall 36 and the side wall 34 and filled with air.

The hollow 38 can be filled with compressed air and can be selectively shielded from the outside. Further, a connecting element (not shown), which can be connected to the compressed air supply equipment so that the compressed air can be filled from the outside, may be additionally provided.

The air chamber 30 is detachably provided to the spoke 20 and the inner ring 10. The side wall 34 may be provided with a guide protrusion 35 protruding in a shape corresponding to the guide groove 24 of the spoke 20 for guiding the air chamber 30 when the air chamber 30 is detached or attached.
