本発明は、飛行機が滑走路に着陸する際の接地車輪のタ
イヤの表面の摩耗を少なくして安定良く着陸し得る飛行
機用接地車輪に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grounding wheel for an airplane that can reduce wear on the tire surface of the grounding wheel when the airplane lands on a runway and land stably. It is.
一般に、飛行機が滑走路に着陸する際は接地車輪は停止
の状態から回転の状態に変わる。Generally, when an airplane lands on a runway, the ground wheels change from a stopped state to a rotating state.
この際には急に接地車輪か滑走路面に圧接され、進行速
度と回転速度とが同しになるまで回転を強いられる。At this time, the ground wheels are suddenly pressed against the runway surface, and the aircraft is forced to rotate until its forward speed and rotational speed are the same.
このときに、接地車輪のタイヤが急に摩耗するが、その
摩耗が多くなるほどタイヤの取替、再製の費用が多くか
かり、接地車輪か急に高速に回り出すほど着陸の円滑さ
がわるくなる欠点がある。At this time, the tires of the grounding wheels suddenly wear out, but the more they wear, the more it costs to replace and remanufacture the tires, and the more quickly the grounding wheels start rotating at high speeds, the less smooth the landing becomes. There is.
C問題点を解決するための手段〕
本発明はこの点を解決したもので、添付図面を参照して
その構成を詳述すると次の通りである。Means for Solving Problem C] The present invention solves this problem, and its configuration will be described in detail with reference to the accompanying drawings as follows.
飛行機1の接地車輪2の側面に接地車輪2か露出した際
に飛行風圧を受けて接地車輪2を自転せしめる風圧受は
袋3を開閉自在に付設したことを特徴としている。A wind pressure receiver that rotates the ground wheel 2 by receiving flight wind pressure when the ground wheel 2 is exposed on the side surface of the ground wheel 2 of the airplane 1 is characterized by having a bag 3 attached to the ground wheel 2 so as to be openable and closable.
第1図の矢印方向に飛行機1が進行してきて着陸するた
めに予め飛行機1が接地車輪2を露出すると開口部4に
飛行風圧を受けた風圧受は袋3は開く。When the airplane 1 advances in the direction of the arrow in FIG. 1 and exposes the grounding wheels 2 in advance for landing, the bag 3 of the wind pressure receiver which receives the flight wind pressure at the opening 4 opens.
このために着陸の前に接地車輪2が矢印方向に自転゛す
る。For this reason, the grounding wheels 2 rotate in the direction of the arrow before landing.
この状態で着陸を開始すると接地車輪2が滑走路面5に
対して摩擦抵抗の小さいころがり接触をするため、それ
だけ飛行機1が円滑に着陸する。When landing is started in this state, the grounding wheels 2 come into rolling contact with the runway surface 5 with low frictional resistance, so that the airplane 1 can land more smoothly.
この風圧受は袋3は開口部4に風圧を受けるときには第
4図に示したように大きく開き、開口部4の反対側に風
圧を受けるときには第3図に示したように偏平になる。In this wind pressure receiver, when the bag 3 receives wind pressure at the opening 4, it opens wide as shown in FIG. 4, and when it receives wind pressure on the opposite side of the opening 4, it becomes flat as shown in FIG.
このために、接地車輪2の一定方向回転が良好に行なわ
れる。For this reason, the rotation of the grounding wheel 2 in a certain direction is performed satisfactorily.
また風圧受は袋3は飛行機1の発進のときにはあまり風
圧を受けずに、偏平になり、その進行を殆ど妨げない。In addition, the wind pressure receiver bag 3 does not receive much wind pressure when the airplane 1 starts, becomes flat, and hardly impedes its progress.
接地車輪2の側面に風圧受は袋3を回転方向に沿って9
個設けた場合を図示している。The wind pressure receiver on the side of the grounding wheel 2 moves the bag 3 along the rotation direction 9
The figure shows a case in which each is provided.
図面の風圧受は袋3は中央で折りたたまれる三角形状の
厚いゴム板で形成した左右側板7と、台形状のやや薄い
ゴム板で形成した上板8と、ゴム板で形成した底板9と
から形成され、上板8と底板9との間に中央で折りたた
まれろ三角形状の薄いゴム板で形成した中仕切板10を
2枚を設けた場合を示している。The wind pressure receiver in the drawing is made up of left and right side plates 7 made of triangular thick rubber plates that can be folded at the center, a top plate 8 made of a trapezoidal slightly thin rubber plate, and a bottom plate 9 made of a rubber plate. The figure shows a case in which two partition plates 10 made of triangular thin rubber plates folded at the center are provided between the top plate 8 and the bottom plate 9.
底板9は接地車輪2のタイヤ6の側面に止着している。The bottom plate 9 is fixed to the side surface of the tire 6 of the grounding wheel 2.
また磁石11を取付けて風圧受は袋3の開閉を確実にな
らしめている。Furthermore, a magnet 11 is attached to the wind pressure receiver to ensure that the bag 3 can be opened and closed.
なお、風圧受は袋3はタイヤ6に一体に設けても良く、
またタイヤ6の両側面に設けても良い。In addition, the wind pressure receiver bag 3 may be provided integrally with the tire 6,
Further, it may be provided on both sides of the tire 6.
本発明は飛行機が着陸するにあたり、接地車輪が露出し
た際に接地車輪の側面の風圧受は袋が飛行風圧を受けて
開閉し、このため滑走路面に対する摩擦抵抗を減らす一
定回転方向に接地車輪が自転し、着陸のときには滑走路

するから、それだけ接地車輪のタイヤの表面の摩擦を少
なくして着陸の開始の際に飛行機が得る衝撃を緩和する
ことができる。In the present invention, when an airplane lands, when the grounding wheel is exposed, the wind pressure receiver on the side of the grounding wheel opens and closes as the bag receives the flight wind pressure, and as a result, the grounding wheel rotates in a constant rotation direction to reduce frictional resistance against the runway surface. The aircraft rotates on its own axis, and during landing, the grounding wheels rotate in the direction of rotation on the runway surface as it starts landing, which reduces the friction on the surface of the tires of the grounding wheels, thereby alleviating the shock the airplane receives when it starts landing. can do.
