図1の(a),(b)に示すように、ガス分離機能付きホイール1は図示しない車軸に連結される円盤状のディスク4と、タイヤ2が装着される環状のリム3とを有し、タイヤ2とリム3の間にタイヤ室5が形成される。 As shown in FIGS. 1A and 1B, the wheel 1 with a gas separation function has a disk-like disk 4 connected to an axle (not shown) and an annular rim 3 on which a tire 2 is mounted. A tire chamber 5 is formed between the tire 2 and the rim 3.
リム3には環状の隔壁6が取り付けられ、リム3と隔壁6の間にガス分離チューブ収容室7が画成される。隔壁6はタイヤ室5とガス分離チューブ収容室7を仕切るものであり、リム3に溶接等によって結合され、タイヤ室5が密閉空間として画成される。 An annular partition wall 6 is attached to the rim 3, and a gas separation tube storage chamber 7 is defined between the rim 3 and the partition wall 6. The partition wall 6 divides the tire chamber 5 and the gas separation tube storage chamber 7 and is joined to the rim 3 by welding or the like, so that the tire chamber 5 is defined as a sealed space.
なお、タイヤ2とリム3の間にタイヤチューブを介装し、このタイヤチューブによってタイヤ室を画成しても良い。 A tire tube may be interposed between the tire 2 and the rim 3, and a tire chamber may be defined by the tire tube.
リム3には複数の空気抜き穴8が周方向に並んで形成され、各空気抜き穴8によってガス分離チューブ収容室7とホイール1の外部が連通される。 A plurality of air vent holes 8 are formed in the rim 3 side by side in the circumferential direction, and the gas separation tube housing chamber 7 and the outside of the wheel 1 communicate with each other through the air vent holes 8.
ガス分離チューブ収容室7には筒状のガス分離チューブ20が介装され、リム3にはガス分離チューブ20の両端に接続した第一プラグ21と第二プラグ22がそれぞれ取り付けられる。 A cylindrical gas separation tube 20 is interposed in the gas separation tube storage chamber 7, and a first plug 21 and a second plug 22 connected to both ends of the gas separation tube 20 are attached to the rim 3.
図1の(b)図は図1の(a)図のB−B線に沿う断面図である。ガス分離チューブ20はガス分離チューブ収容室7にてC字形に延び、第一プラグ21と第二プラグ22は互いに近接して配置される。 FIG. 1B is a cross-sectional view taken along the line BB in FIG. The gas separation tube 20 extends in a C shape in the gas separation tube storage chamber 7, and the first plug 21 and the second plug 22 are disposed close to each other.
図2に示すように、ガス分離ユニット19は、ガス分離チューブ20の一端に絞り23を介して第一プラグ21が接続され、ガス分離チューブ20の他端に絞り24を介して第二プラグ22が接続される。 As shown in FIG. 2, in the gas separation unit 19, a first plug 21 is connected to one end of a gas separation tube 20 via a throttle 23, and a second plug 22 is connected to the other end of the gas separation tube 20 via a throttle 24.

第一プラグ21には図示しない逆止弁が介装され、図示しない空気ポンプ等の空気充填口から導入される高圧空気がこの逆止弁を通ってガス分離チューブ20の一端に充填される。 A check valve (not shown) is interposed in the first plug 21, and high-pressure air introduced from an air filling port such as an air pump (not shown) is filled into one end of the gas separation tube 20 through the check valve.
ガス分離チューブ20は図に矢印で示すように空気中の酸素リッチガス(酸素濃度が大気より高くなったガス)を透過させるガス分離膜によって形成される。第一プラグ21からガス分離チューブ20に充填された空気が第二プラグ22の方に流れる過程で図2に矢印で示すように酸素リッチガスがガス分離膜を透過してガス分離チューブ20の外部に出される。ガス分離チューブ20の外に出された酸素リッチガスはガス分離チューブ収容室7から各空気抜き穴8を通ってホイール1の外部に排出される。 The gas separation tube 20 is formed of a gas separation membrane that allows oxygen-rich gas in the air (gas whose oxygen concentration is higher than the atmosphere) to pass through, as indicated by arrows in the figure. In the process in which the air filled in the gas separation tube 20 from the first plug 21 flows toward the second plug 22, the oxygen-rich gas permeates the gas separation membrane as shown by the arrow in FIG. Is issued. The oxygen-rich gas discharged out of the gas separation tube 20 is discharged from the gas separation tube housing chamber 7 through the air vent holes 8 to the outside of the wheel 1.
第二プラグ22には図示しない逆止弁が介装され、ガス分離チューブ20によって導かれる窒素リッチガス(窒素濃度が大気より高くなったガス)がこの逆止弁を通ってタイヤ室5に充填される。 A check valve (not shown) is interposed in the second plug 22, and nitrogen-rich gas (gas whose nitrogen concentration is higher than the atmosphere) guided by the gas separation tube 20 is filled into the tire chamber 5 through the check valve. The
ガス分離機能付きホイール1は以上のように構成されて、次に作用及び効果について説明する。 The wheel 1 with a gas separation function is configured as described above, and the operation and effect will be described next.
タイヤ室5に窒素リッチガスを充填する場合、図示しない空気ポンプ等の充填口を第一プラグ21に装着し、充填口に供給される高圧空気を第一プラグ21からガス分離チューブ20内に充填し、この空気がガス分離チューブ20の一端から他端に流れる過程で酸素リッチガスがガス分離膜を透過してガス分離チューブ20の外に出されて空気中の窒素濃度が次第に高くなって窒素リッチガスとなり、この窒素リッチガスが第二プラグ22からタイヤ室5に充填される。 When filling the tire chamber 5 with nitrogen-rich gas, a filling port such as an air pump (not shown) is attached to the first plug 21, and high-pressure air supplied to the filling port is filled into the gas separation tube 20 from the first plug 21. As the air flows from one end of the gas separation tube 20 to the other end, the oxygen-rich gas permeates the gas separation membrane and exits the gas separation tube 20, and the nitrogen concentration in the air gradually increases to become nitrogen-rich gas. The nitrogen rich gas is filled into the tire chamber 5 from the second plug 22.
ガス分離チューブ20の外に出された酸素リッチガスは各空気抜き穴8を通ってホイール1の外部へと排出される。 The oxygen-rich gas discharged out of the gas separation tube 20 is discharged to the outside of the wheel 1 through each air vent hole 8.
本実施形態において、ガス分離機能付きホイール1はホイール1とタイヤ2の間に画成されるタイヤ室5と、ホイール1に取り付けられる酸素透過用ガス分離チューブ20と、このガス分離チューブ20に接続される第一、第二プラグ21,22とを備え、この第一プラグ21からガス分離チューブ20内に充填された空気の酸素リッチガスがガス分離チューブ20の外部に出され、ガス分離チューブ20によって導かれる窒素リッチガスが第二プラグ22からタイヤ室5に充填される構成としたため、通常の空気ポンプによってタイヤ室5に窒素リッチガスを容易に充填することができ、例えば窒素リッチガスの製造装置や窒素ガスボンベ等を用いる必要がない。 In the present embodiment, the wheel 1 with a gas separation function is connected to a tire chamber 5 defined between the wheel 1 and the tire 2, an oxygen permeable gas separation tube 20 attached to the wheel 1, and the gas separation tube 20. The first and second plugs 21 and 22 are provided, and the oxygen rich gas of the air filled in the gas separation tube 20 is discharged from the first plug 21 to the outside of the gas separation tube 20. Since the introduced nitrogen rich gas is filled into the tire chamber 5 from the second plug 22, the tire chamber 5 can be easily filled with a normal air pump. Etc. need not be used.
本実施形態において、ガス分離機能付きホイール1はホイール1とタイヤ室5との間に形成されガス分離チューブ20が介装される環状のガス分離チューブ収容室7と、このガス分離チューブ収容室7とホイール1の外部を連通する空気抜き穴8とを備えたため、ガス分離チューブ20から出た酸素リッチガスが空気抜き穴8からホイール1の外部に排出される。また、ガス分離チューブ20の取り付けが確実に行われる。 In this embodiment, the wheel 1 with a gas separation function is formed between the wheel 1 and the tire chamber 5 and has an annular gas separation tube housing chamber 7 in which a gas separation tube 20 is interposed, and the gas separation tube housing chamber 7. And the air vent hole 8 communicating with the outside of the wheel 1, the oxygen-rich gas discharged from the gas separation tube 20 is discharged from the air vent hole 8 to the outside of the wheel 1. Further, the gas separation tube 20 is securely attached.
本実施形態において、ガス分離機能付きホイール1はガス分離チューブ20の両端に第一、第二プラグ21,22をそれぞれ接続したため、第一プラグ21からガス分離チューブ20に充填された空気が第二プラグ22の方に流れる過程で透過してガス分離チューブ20の外部に出され、第二プラグ22からタイヤ室5に充填されるガスの窒素濃度を高められる。 In this embodiment, since the wheel 1 with a gas separation function has the first and second plugs 21 and 22 connected to both ends of the gas separation tube 20, the air filled in the gas separation tube 20 from the first plug 21 is second. The nitrogen concentration of the gas filled in the tire chamber 5 from the second plug 22 is increased by permeating in the process of flowing toward the plug 22 and exiting the gas separation tube 20.
本実施形態において、ガス分離機能付きホイール1は第二プラグ22にタイヤ室5からガス分離チューブ20へのガスの流れを止める逆止弁を介装したため、タイヤ室5の圧力を維持できる。 In the present embodiment, the wheel 1 with a gas separation function can maintain the pressure in the tire chamber 5 because the second plug 22 is provided with a check valve that stops the flow of gas from the tire chamber 5 to the gas separation tube 20.
次に図3の(a),(b)に示す他の実施形態は、図示しない既存のホイールに取り付けられるガス分離チューブ収容管30を備え、このガス分離チューブ収容管30内に図2に示すガス分離ユニット19が介装される。 Next, another embodiment shown in FIGS. 3A and 3B includes a gas separation tube housing tube 30 attached to an existing wheel (not shown), and this gas separation tube housing tube 30 is shown in FIG. A gas separation unit 19 is interposed.
ガス分離チューブ収容管30はゴム材によって形成され伸縮可能なベローズ筒部31と、このベローズ筒部31の一端に接続される第一アダプタ32と、ベローズ筒部31の他端に接続される第二アダプタ33とを備える。なお、ベローズ筒部31はゴム材に限らず、金属、樹脂等によって形成しても良い。 The gas separation tube housing tube 30 is formed of a rubber material and can be expanded and contracted, a first adapter 32 connected to one end of the bellows tube portion 31, and a first adapter connected to the other end of the bellows tube portion 31. Two adapters 33 are provided. The bellows cylinder portion 31 is not limited to a rubber material, and may be formed of metal, resin, or the like.
ガス分離チューブ収容管30はタイヤ室に設けられ、図示しないテープあるいは接着剤等によってリムに固定される。 The gas separation tube housing tube 30 is provided in the tire chamber and is fixed to the rim with a tape or an adhesive (not shown).
第一アダプタ32はホイールのリムに形成された穴に取り付けられ、第一アダプタ32内にガス分離ユニット19の第一プラグ21が介装される。 The first adapter 32 is attached to a hole formed in the rim of the wheel, and the first plug 21 of the gas separation unit 19 is interposed in the first adapter 32.
図3の(a)に示すように、第一アダプタ32には複数の空気抜き穴34が形成され、各空気抜き穴34によってガス分離チューブ収容管30内とホイールの外部とが連通される。 As shown in FIG. 3A, a plurality of air vent holes 34 are formed in the first adapter 32, and the inside of the gas separation tube housing tube 30 and the outside of the wheel communicate with each other through the air vent holes 34.
第二アダプタ33内にガス分離ユニット19の第二プラグ22が介装される。 The second plug 22 of the gas separation unit 19 is interposed in the second adapter 33.
以上のように構成されて、タイヤ室に窒素リッチガスを充填する場合、図示しない空気ポンプ等の充填口を第一プラグ21に装着し、充填口に供給される高圧空気を第一プラグ21からガス分離チューブ20内に充填し、この空気がガス分離チューブ20の一端から他端に流れる過程で酸素リッチガスがガス分離膜を透過してガス分離チューブ20の外に出されて空気中の窒素濃度が次第に高くなって窒素リッチガスとなり、この窒素リッチガスが第二プラグ22からタイヤ室に充填される。 When the tire chamber is filled with nitrogen-rich gas configured as described above, a filling port such as an air pump (not shown) is attached to the first plug 21, and high-pressure air supplied to the filling port is gas from the first plug 21. In the process of filling the separation tube 20 and this air flows from one end of the gas separation tube 20 to the other end, the oxygen-rich gas passes through the gas separation membrane and is discharged out of the gas separation tube 20 so that the nitrogen concentration in the air is increased. The gas gradually increases to become a nitrogen-rich gas, and the nitrogen-rich gas is filled into the tire chamber from the second plug 22.
ガス分離チューブ20の外に出された酸素リッチガスはガス分離チューブ収容管30内から各空気抜き穴34を通ってホイールの外部へと排出される。 The oxygen-rich gas discharged out of the gas separation tube 20 is discharged from the gas separation tube housing tube 30 through the air vent holes 34 to the outside of the wheel.
本実施形態において、ガス分離機能付きホイールはホイールの外周に取り付けられるガス分離チューブ収容管30を備え、このガス分離チューブ収容管30内にガス分離チューブ20を介装したため、既存のホイールにガス分離チューブ収容管30を取り付けることにより容易に実施できる。 In the present embodiment, the wheel with a gas separation function includes a gas separation tube housing tube 30 attached to the outer periphery of the wheel, and the gas separation tube 20 is interposed in the gas separation tube housing tube 30, so that gas separation is performed on the existing wheel. This can be easily implemented by attaching the tube housing tube 30.
本実施形態において、ガス分離チューブ収容管30は第一プラグ21が介装される第一アダプタ32をホイールに取り付け、この第一アダプタ32にガス分離チューブ収容管30内とホイールの外部を連通する空気抜き穴34を形成したため、ガス分離チューブ20から出た酸素リッチガスが第一アダプタ32の空気抜き穴34からホイールの外部に排出され、ホイールに空気抜き穴を形成する必要がない。 In this embodiment, the gas separation tube housing tube 30 is attached to the wheel with a first adapter 32 in which the first plug 21 is interposed, and the inside of the gas separation tube housing tube 30 communicates with the outside of the wheel. Since the air vent hole 34 is formed, the oxygen-rich gas emitted from the gas separation tube 20 is discharged from the air vent hole 34 of the first adapter 32 to the outside of the wheel, and there is no need to form an air vent hole in the wheel.
本発明は上記の実施の形態に限定されずに、その技術的な思想の範囲内において種々の変更がなしうることは明白である。 The present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.
