[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tire having a hollow portion filled with a liquid together with air.

[0002]

[Prior Art]

 BACKGROUND ART Tires used in vehicles such as automobiles are filled with pressurized air in order to absorb a shock from the road surface and ensure smooth running. In addition, in order to improve maneuverability and stability during driving, the amount of air pressure to be charged was adjusted in the current pneumatic tires.

However, merely adjusting the air pressure in the tire is not sufficient for achieving the above-described maneuverability and stability during traveling. From this point of view, the present inventors have The invention of Japanese Patent Laid-Open No. 2-141303 has been proposed. The present invention has a configuration in which a liquid is filled together with air in the hollow portion of a tube tire or a tubeless tire.

In the above-described invention, when the tire is running and rotating, the liquid filled inside is localized on the outer diameter side of the tire due to the action of centrifugal force, so that the mass of the tire as a high-speed rotating body is increased. An increase in inertia due to the increase, that is, a so-called flywheel effect is formed.

As a result, for example, a braking distance can be shortened when a brake is applied, fuel consumption can be reduced, a cooling effect that heat can be taken by high-speed rotation can be obtained, and vibration during traveling can be absorbed. There are many advantages.

[Problems to be solved by the device]

However, in the above-described conventional invention, if there is only one valve port for injecting air or liquid inside, various problems may occur. That is, there is no problem in first filling a predetermined amount of liquid and then filling air. However, if it is attempted to fill the liquid after filling the air as necessary, there is a problem that the liquid is difficult to fill because the air is filled under a predetermined pressure.

Further, when the liquid inside is to be discharged in order to replace the liquid, it is extremely difficult to discharge the liquid if there is only one valve port. As explained in the above-mentioned conventional example, the liquid to be filled in is mainly water, but there are cases where an antifreeze liquid is used from the viewpoint of preventing freezing. It is necessary to drain the internal liquid when exchanging with the liquid or vice versa. Therefore, the present invention makes it possible to drain the internal liquid very easily.

[0008]

[Means for Solving the Problems]

 The present invention is a tire in which a hollow portion of a tube tire or a tubeless tire is filled with a liquid together with air, and has a structure in which a ventilation valve and a water passage valve are provided on the inner peripheral surface.

Further, the rim wheel mounted on the inner peripheral surface of the tire may be provided with holes through which the ventilation valve and the water passage valve pass.

[0010]

[Action]

 As a result of the configuration described above, air is filled from the ventilation valve and liquid is filled and discharged from the water passage valve. In particular, when the liquid is discharged from the water passage valve, if the ventilation valve is left open, the ventilation valve acts as a so-called air hole, and the liquid can be discharged very smoothly.

However, if the ventilation valve and the water passage valve are located close to each other, the ventilation valve is not opened because the liquid blocks the liquid inside the ventilation valve. Therefore, it is desirable that the ventilation valve and the water passage valve be installed at some distance from each other.

[0012]

【Example】

 The drawing shows a cross section of a tubeless tire 1, in which a rim wheel 2 is mounted on the inner peripheral surface, and a ventilation valve 3 and a water passage valve 4 communicating with the tire 1 and protruding from the inner peripheral surface are The rim wheel 2 is located in the rim wheel 2 by penetrating a hole 5 formed in the rim wheel 2.

The mutual positions of the ventilation valve 3 and the water passage valve 4 are set such that the liquid A does not block the ventilation valve 3 when the liquid A is discharged from the water passage valve 4 and the ventilation valve 3 is in an open state. It is set from the viewpoint of being able to maintain it. In the illustrated embodiment, the ventilation valve 3 is used as a reference, and the tire 1 is set at any position with a central angle of 45 degrees from the imaginary center point.

The liquid A filled inside is mainly water, but antifreeze is used in regions and seasons where freezing is likely to occur. The filling amount of the liquid A varies depending on the vehicle type, weight, etc., but assuming that this amount is large, it is preferable that the ventilation valve 3 and the water passage valve 4 be located as far apart as possible.

Further, the mutual position of the ventilation valve 3 and the water passage valve 4 is set to any position of the central angle of 45 degrees from the central point of the tire 1 because the rim wheel 2 is fixed to the axle. It corresponds to the fixing bolt at the time.

[Effect of the device]

 INDUSTRIAL APPLICABILITY As described above, the present invention relates to a tire in which a hollow portion of a tube tire or a tubeless tire is filled with a liquid together with air, and a ventilation valve for filling the inner peripheral surface of the tire with a fluid for filling and discharging the liquid. Since the water valve and the water valve are separately provided, an excellent effect that the work can be smoothly performed when the liquid is discharged is exhibited.
