Abstract
Description
本発明は、鉄道車両用の車輪である。 The present invention is a wheel for a railway vehicle.
従来技術においては、鉄道車両に使用されている車輪は、その大半が鋼材のみで作られている。そのために、車輪とレールが擦れ合うことで騒音が発生する。
列車の騒音の主な原因は、▲１▼レールと車輪が振動することで放射される音。▲２▼車輪とレールが擦れ合うことで生じる音。▲３▼電車そのものから出る音等がある。In the prior art, most of the wheels used in railway vehicles are made only of steel. Therefore, noise is generated by the friction between the wheel and the rail.
The main cause of train noise is (1) the sound emitted by the vibration of rails and wheels. (2) Sound generated when the wheel and rail rub against each other. (3) There are sounds coming from the train itself.
現在の騒音対策としては、▲１▼車輪・レールの削正。▲２▼円弧踏面の車輪の導入。▲３▼弾性車輪や防音車輪の導入。▲４▼電車の軽量化と台車の改良。▲５▼線路の防振防音対策。▲６▼塗油器の設置等がある。
列車の騒音は、市街地の地上を走る鉄道においては、近隣住民への騒音被害をもたらし、地下鉄においては、トンネルという特殊な環境下でもあるため、乗員・乗客に多大な騒音をもたらしている。Current noise countermeasures are as follows: (1) Wheel and rail correction. (2) Introduction of wheels with arc treads. (3) Introduction of elastic wheels and soundproof wheels. 4) Lighter trains and improved carts. (5) Anti-vibration and sound-proofing measures for the track. (6) There are installation of oiling equipment.
The noise of trains causes noise damage to neighboring residents in railways that run on the ground in urban areas, and in the subway in a special environment called tunnels, it causes a great deal of noise to passengers and passengers.
踏面形状とフランジ遊間をもってしても吸収しきれない行路差のあるカーブにおいては、フランジがレールと接触しながら走行することになる。フランジとレールが接触することが、騒音（振動）の原因になっている。 In a curve with a path difference that cannot be absorbed even with the tread shape and flange clearance, the flange travels in contact with the rail. Contact between the flange and rail causes noise (vibration).
現在の鉄道車輪は、騒音対策として、先に挙げた弾性車輪や防音車輪を導入してはいるが、弾性車輪は普及せず、リング式防音車輪とゴムサンドイッチ式防音車輪が開発されている。これは、リム内周部分に防音リングをはめた車輪であり、騒音の発生原因であるフランジとレールの接触に対して対策を施したものではない。 The current railway wheels have introduced the elastic wheels and soundproof wheels mentioned above as noise countermeasures, but the elastic wheels are not widespread, and ring type soundproof wheels and rubber sandwich type soundproof wheels have been developed. This is a wheel in which a soundproof ring is fitted to the inner peripheral portion of the rim, and no measures are taken against contact between the flange and the rail, which is the cause of noise generation.
現在の鉄道車輪では、直線走行特性（蛇行動の防止）と曲線走行特性の両立のために、修正円弧踏面が多く採用されている。この修正円弧踏面では、フランジがレールと接触する過程で、その接触点が踏面からフランジにジャンプすることがないよう、接触点ができるだけ連続的に変化するように設計されている。 In current railway wheels, a modified arc tread is often used to achieve both a straight running characteristic (preventing snake behavior) and a curved running characteristic. The modified arc tread is designed so that the contact point changes as continuously as possible so that the contact point does not jump from the tread to the flange in the process of contact of the flange with the rail.
また、フランジは、脱線を食い止める最後の砦であり、フランジの立ち上がり角度が急なほど脱線しにくくなるが、分岐器の通過に問題が生じ、踏面との滑らかな接続が難しくなる。よって、フランジの立ち上がり角度は、修正円弧踏面の車輪では６５°、新幹線などでは７０°となっている。 In addition, the flange is the last fort to stop derailment, and the steep rise angle of the flange makes it difficult for derailment. Therefore, the rising angle of the flange is 65 ° for the modified arc tread wheel and 70 ° for the Shinkansen.
本発明は、このフランジの立ち上がり部分に、摩擦係数が低く尚且つ、耐摩耗性に優れた硬質樹脂を埋め込んだものである（図１）。
これにより、フランジとレールの金属同士の接触を減少させ、発生する金属音を大幅に小さくすることができる。In the present invention, a hard resin having a low friction coefficient and excellent wear resistance is embedded in the rising portion of the flange (FIG. 1).
Thereby, the contact between the metal of a flange and a rail can be reduced and the metal sound which generate | occur | produces can be made significantly small.
具体的には、図１にあるように、６５°ないし７０°の角度を持つフランジの立ち上がり部分に溝を作り、その溝に摩擦係数が低く耐摩耗性に優れた硬質樹脂を埋め込む。
樹脂においても当然摩耗するので、定期的に交換する必要がある。このことも考慮して、フランジへの樹脂の取り付け方法を決定するとよい（接着やはめ込み式等）。Specifically, as shown in FIG. 1, a groove is formed in the rising portion of the flange having an angle of 65 ° to 70 °, and a hard resin having a low friction coefficient and excellent wear resistance is embedded in the groove.
Since the resin naturally wears, it must be replaced periodically. Considering this, it is preferable to determine a method of attaching the resin to the flange (adhesion, fitting type, etc.).
地上を走行する鉄道においては、近隣住民への騒音公害を減らし、地下鉄においては、車両内部に居る乗員・乗客の環境を飛躍的に改善することができる。
また、鉄道車両の脱線の原因のひとつでもある、フランジのレールへの乗り上げの可能性を低下させ、鉄道の安全性の向上にも寄与することができる。In the railway running on the ground, noise pollution to neighboring residents can be reduced, and in the subway, the environment of passengers and passengers inside the vehicle can be dramatically improved.
In addition, the possibility of riding on the rail of the flange, which is one of the causes of derailment of the railway vehicle, can be reduced, which can contribute to the improvement of the safety of the railway.
