Description

Double gas storage wheel

The present invention relates to a wheel, and more particularly to a dual gas storage wheel.

Most of the wheels used in existing automobiles and locomotives do not have inner tubes, that is, directly join a tire to a rim, and then fill the gas between the tire and the rim to provide the required strength and cushioning capacity of the wheel. However, once the tire is pierced by foreign objects or the gas pressure inside the wheel is too high, the tire will be deformed if the vehicle is driving. Even if the tire skin is scattered everywhere and directly contact the ground with the rim, it is easy to cause The vehicle is out of control and even a traffic accident.

Therefore, the advent of explosion-proof tires, such as the Republic of China Bulletin No. M291376 "Structure of automobile explosion-proof tires" invention patent case is an example. The utility model mainly comprises adding a sub-tire in a pneumatic tire, and if the puncture occurs when the vehicle is running, the pneumatic tire and the rim are spaced by the sub-tire, thereby preventing the rim from being deformed due to contact with the ground, thereby preventing the automobile from being damaged. Lost balance due to a puncture. However, when assembling the pneumatic tire before the rim, the sub-tire must be installed on the limit seat on the periphery of the rim. Since the sub-tire is elastic material, the sub-tire is to be placed. Fixed in the limit seat and Not easy, resulting in increased assembly difficulties.

In addition, since the pneumatic tire is only the thickness of a general tire specification, although the subtire can be obtained by the tire when the tire is blown, the pneumatic tire is easily subjected to sharp object puncture and has a risk of bursting without adjusting the thickness. .

Therefore, an object of the present invention is to provide a double-layer gas storage space between a rim and a tire, and when the tire is blown up, the piston assembly can still drive the piston assembly through the pressure change of the double-layer gas storage space. Prevents excessive deformation of the tires to avoid double-storage wheels that are out of control during vehicle travel.

Thus, the dual gas storage wheel of the present invention comprises a rim, a tire, and a plurality of single acting cylinders. The rim includes an inner wheel frame, a wheel frame surrounding the outer circumference of the inner wheel frame, and a first gas storage space defined by the inner wheel frame and the outer wheel frame and filled with a gas. The tire is joined to the outer circumference of the outer wheel frame, and a second gas storage space filled with gas is defined between the inner wall surface of the tire and the outer wheel frame. The single-acting cylinders are disposed in the inner wheel frame and are located in the first gas storage space. Each single-acting cylinder includes a gas chamber communicating with the first gas storage space, and the air chamber and the first a venting opening in the gas storage space, and a piston assembly displaceable relative to the plenum between a fully extended position and a fully collapsed position, the piston assembly being capable of being in the fully extended position when the tire is intact Supporting the inner wall surface of the tire and disengaging the second gas storage space with the gas chambers, wherein the first gas storage space and the second gas storage space are equal to the internal gas pressure of the gas chambers; When traveling on an uneven road surface, the piston assemblies are linearly displaced between the fully extended position and the fully collapsed position, and when the tire is pressed against one of the uneven portions of the uneven road surface, the tire is pushed The piston assemblies are moved away from the fully extended position such that the second gas storage space communicates with the gas chambers and the air chambers are separated from an upper interval and a lower interval, and gas inflows in the second gas storage space In the upper sections of the plenums, the gases in the lower sections of the plenums flow from the vents into the first gas storage space, the tires leaving the protuberances on the uneven road surface At the time, the gas in the first gas storage space flows into the lower intervals of the gas chambers through the vents and pushes the piston assemblies toward the fully extended position, thereby simultaneously urging the gas chambers The gas in the upper section flows into the second gas storage space, and the upper sections of the gas chambers disappear when the piston assemblies return to the fully extended position; and when the tire is broken, the second storage Gas leakage in the gas space, the The air pressure in the air chamber and the first air storage space is greater than the air pressure in the second air storage space, so that the piston assemblies are still in the fully extended position and supported on the inner wall surface of the tire to maintain the tire in a circular shape. motion.

The effect of the present invention is that, by the arrangement of the first gas storage space and the second gas storage space, and the operation of the single-acting cylinders, the single-acting cylinders are driven by the change of the air pressure in the double-layer gas storage space. The telescopic displacement of the piston assembly, especially when the tire is blown, the air pressure inside the second gas storage space may be decreased due to gas leakage, but the gas pressure inside the gas chamber and the first gas storage space is greater than The air pressure inside the second gas storage space, so as to drive the piston assemblies to maintain the protrusion and support the inner wall surface of the tire. In this way, it can ensure that the tire maintains circular motion for a period of time even if a tire burst occurs, avoiding the vehicle from being out of control, and allowing the driver to have sufficient reaction time to do the corresponding measures, which is not easy to cause a traffic accident.

Of course, the shape of the concave groove 364 is not limited to a star shape.

Referring to Figures 1, 2, and 3, in use, an inflating tool (not shown) is used to input gas into the first gas storage space 13 through the first valve 14, in the first gas storage space 13. The gas is further circulated through the vents 312 through the vents 312. It is to be noted that the gas used in the embodiment is air, but is not limited thereto. By controlling the intake air amount, the air pressure level, and the air pressure balance, the piston assemblies 32 are outwardly protruded by the air pressure thrust in the air chambers 311 and are supported on the inner wall surface of the tire 2, waiting for the first After the air storage space 13 and the air pressure values in the air chambers 311 reach a preset value, the air inflating tool can be pulled out. The gas is introduced into the second gas storage space 23 through the third valve 16 by using the inflation tool (not shown). After the gas pressure value in the second gas storage space 23 reaches a preset value, Pull out the inflatable tool. So the double gas storage wheel can be further A hub 4 is coupled, that is, by placing the hub 4 into the central cylinder 111 from the opening 114, and is screwed to the first cover 112 of the inner wheel frame 11 by a plurality of screw-locking elements 6, thereby It is then installed at the end of an axle 5 to provide the vehicle for driving.

In the initial state, the piston assemblies 32 of the dual-gas storage wheel are subjected to the air pressure thrust in the air chambers 311 to be in the fully extended position (ie, the position shown in Figures 2 and 3). The support plate 36 is supported by the inner wall surface of the tire 2, and the top surfaces of the piston bodies 333 are in close contact with the piston caps 35 to close the working holes 353, and the second gas storage space 23 and the gas chambers 311 are Not connected.

Referring to Figures 3 and 5, when the dual-gas storage wheel travels on an uneven road surface (not shown), the piston assemblies 32 are interlocked in the fully extended position (as shown in Figure 2) and The telescopic displacement is performed between the fully collapsed position (the position shown in FIG. 7), and when the tire 2 is pressed to one of the protrusions on the uneven road surface, the support plate 36 of the piston assembly 32 is pushed toward the outer wheel. The displacement of the frame 12 is such that the piston bodies 333 are disengaged from the piston caps 35, so that the second gas storage space 23 communicates with the gas chambers 311, and the displacement of the piston bodies 333 is such that The gas chamber 311 is divided into an upper section and a lower section, and the gas in the second gas storage space 23 flows into the upper section of the gas chamber 311 through the working holes 353, and the gas located in the lower section of the gas chamber 311 is The pressure of the gas in the second gas storage space 23 is smaller than the gas pressure in the gas chambers 311 by the venting of the piston bodies 333. The gas pressure in the gas chamber 311 is smaller than the gas pressure in the first gas storage space 13 Therefore, when the tire 2 leaves the ridge on the road surface, the top thrust of the support plate 36 acting on the piston assemblies 32 disappears, and the gas in the first gas storage space 13 is then ventilated. The port 312 flows into the lower section of the plenums 311, thereby generating an urging force for the piston bodies 333 to cause the movable rods 33 to generate an extension displacement toward the fully extended position (ie, the position shown in FIG. 2). The gas in the upper section of the gas chambers 311 also flows into the second gas storage space 23 from the working holes 353 under the pushing of the piston bodies 333, and the piston assemblies 32 return to the fully extended position. The upper intervals of the air chambers 311 disappear.

When the tire 2 is punctured or a puncture occurs, the internal air pressure is lowered due to the leakage of the gas in the second gas storage space 23, and the gas chamber 311 and the first gas storage space 116 are at this time. The internal air pressure is greater than the air pressure in the second air storage space 23, and the piston assemblies 32 are subjected to the air pressure thrust in the air chambers 311, and the top surfaces of the piston bodies 333 are more closely attached to the surrounding wall of the outer wheel frame 12. 121, to strengthen the sealing of the working holes 353, so that the supporting plate 36 of the piston assembly 32 can be continuously supported on the inner wall surface of the tire 2, thereby ensuring that the tire 2 can be maintained for a period of time even if a puncture occurs. The circular motion avoids the out-of-control situation of the vehicle due to the puncture, so that the driver has enough reaction time to do the corresponding measures, so it is not easy to cause traffic accidents, and can also protect the safety of the driver and others around.

Referring to Figures 3, 6, and 7, when the tire 2 needs to be replaced, the gas in the first gas storage space 13 can be discharged by simply pumping the second valve 15 with an air suction tool. The gas in the chamber 311 is also discharged to the outside through the vent 312 and the first gas storage space 13 along with the gas The air pressure in the chamber 311 and the first gas storage space 13 is reduced, and is affected by the air pressure in the second gas storage space 23, and the piston assemblies 32 are gradually retracted until the pressing nuts 34 are in conflict with each other. The piston cover 35, the piston assemblies 32 are in the fully collapsed position, and the support plates 36 are adjacent to each other. The third valve chamber 16 is further exhausted by the third valve chamber 23. Thus, the tire 2 can be detached from the outer wheel frame 12 by the easy operation of the ripper tool.

In summary, the dual gas storage wheel of the present invention can be designed to interlock the displacement of the piston assembly 32 of the single-acting cylinder 3 when the uneven surface is encountered during the traveling process. When a puncture occurs, the internal air pressure of the second gas storage space 23 is lowered due to gas leakage, because the internal gas pressure of the gas chamber 311 and the second gas storage space 23 is greater than the inside of the second gas storage space 23 The air pressure, so that the piston assembly 32 can still be supported against the inner wall surface of the tire 2, thus ensuring that the tire 2 maintains a circular motion for a period of time even if a tire blow occurs, thereby preventing the vehicle from being out of control and allowing the driving The personnel have sufficient reaction time to do the response measures, which is not easy to cause traffic accidents, thus ensuring the safety of the driver and others around. In addition, when the tire 2 needs to be replaced, the first gas storage space 13, the gas chamber 311, and the second portion can be made through the second valve 15 and the third valve 16 by using an air suction tool. The gas in the gas storage space 23 is discharged, and the tire 2 can be easily detached from the outer ring frame 12 or attached to the outer ring frame 12 by the easy operation of the ripper tool, thereby having the advantage of being more convenient to use. Therefore, the object of the present invention can be achieved.

However, the above is only an embodiment of the present invention, when The scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the present invention in the scope of the invention and the patent specification are still within the scope of the invention.
