Description

本発明は、磁気浮上式車両の支持車輪タイヤのパンク検知装置に関するものである。   The present invention relates to a puncture detection device for supporting wheel tires of a magnetically levitated vehicle.

従来、磁気浮上式車両は、浮上時には支持車輪タイヤを用いる必要はないが、車両が浮上する前、及び車両が着陸する時には支持車輪タイヤを使用するようになっている。
磁気浮上式車両は車輪走行時に各台車に装備する支持車輪タイヤで走行する。したがって、万一支持車輪タイヤにパンクが発生した場合には、速やかに停止処置を取る必要があるので、支持車輪タイヤのパンク発生の検出機能が重要である。 Conventionally, a magnetically levitated vehicle need not use a supporting wheel tire when ascending, but uses a supporting wheel tire before the vehicle ascends and when the vehicle lands.
A magnetically levitated vehicle travels with supporting wheel tires that are mounted on each vehicle during wheel traveling. Therefore, in the unlikely event that puncture occurs in the support wheel tire, it is necessary to take a stop treatment promptly, so the function of detecting the occurrence of puncture in the support wheel tire is important.

一方、使用する支持車輪タイヤは中空であるため、現在は各支持車輪タイヤの内圧を直接センサで検出する内圧検知装置を各支持車輪に装備して、支持車輪パンクに至る前の内圧を監視しているが、現状の装置は構造が非常に複雑で、且つ高価なシステムとなっている。
図４はかかる従来の磁気浮上式車両のタイヤを示す図、図５はそのタイヤの空気圧を検出する圧力センサを示す図である。 On the other hand, since the supporting wheel tires used are hollow, each supporting wheel is now equipped with an internal pressure detection device that directly detects the internal pressure of each supporting wheel tire to monitor the internal pressure before reaching the supporting wheel puncture. However, the current apparatus has a very complicated structure and is an expensive system.
FIG. 4 is a view showing a tire of such a conventional magnetically levitated vehicle, and FIG. 5 is a view showing a pressure sensor for detecting the air pressure of the tire.

図４及び図５において、１０１は磁気浮上式車両の支持車輪タイヤ（中空）、１０２は外接補助輪、１０３は圧力センサの取付部、１０４は引出しケーブル、１０５はセンサ信号伝達回路を収納するケース、１０６はタイヤホイールである。
このような磁気浮上式車両の支持車輪タイヤ１０１には、圧力センサ（図示なし）が設けられ、その圧力センサからの出力信号が、引出しケーブル１０４を介して、ケース１０５に導出されるようになっている。 4 and 5, 101 is a supporting wheel tire (hollow) of a magnetically levitated vehicle, 102 is a circumscribing auxiliary wheel, 103 is a pressure sensor mounting portion, 104 is a drawer cable, and 105 is a case for housing a sensor signal transmission circuit. 106 are tire wheels.
The support wheel tire 101 of such a magnetically levitated vehicle is provided with a pressure sensor (not shown), and an output signal from the pressure sensor is led out to the case 105 via the lead-out cable 104. ing.

また、普通の自動車用タイヤにおいては、（１）タイヤセンサをインテロゲートするシステムがあり、センサと電気導体を備えるホイールが設けられ、電気導体はホイールの回転軸の周囲に延び、センサは電気導体に電気的に連結される。このように構成することで、センサとインテロゲーション用遠隔装置との間の通信が改善されるようにしている（下記特許文献１参照）。（２）タイヤホイールのリムの一部に監視センサーを取付けるタイヤ状態監視装置の取付け構造において、前記リムの一部にセンサー本体とセンサーホルダーとで構成される監視センサーを嵌合装着するための嵌合部を形成し、この嵌合部に、前記リムの表面から前記監視センサーを突出しないように取り付けるようにしたものが開示されている（下記特許文献２参照）。
特表２００５−５３７１６６号公報 特開２００５−３２４７３２号公報 Also, in ordinary automobile tires, (1) there is a system that interrogates a tire sensor, a wheel including a sensor and an electric conductor is provided, the electric conductor extends around the rotation axis of the wheel, and the sensor is electrically Electrically connected to the conductor. With this configuration, communication between the sensor and the remote device for interrogation is improved (see Patent Document 1 below). (2) In a tire condition monitoring device mounting structure in which a monitoring sensor is attached to a part of a rim of a tire wheel, a fitting for fitting and mounting a monitoring sensor composed of a sensor body and a sensor holder on the part of the rim. A joint portion is formed, and the monitoring sensor is attached to the fitting portion so as not to protrude from the surface of the rim (see Patent Document 2 below).

しかしながら、上記したように、現状の内圧検知装置は、高速でかつ振動がある劣悪な環境下での使用となるために、構造が非常に複雑で信頼度を確保するために高価なシステムとなっている。
また、従来の普通の自動車用タイヤの監視装置は、その構成が複雑であるといった問題があった。 However, as described above, the current state of the internal pressure sensing device, a high speed huge one vibration there Ru for the use in harsh environment, expensive system in order to ensure a very complex reliability structure It has become.
Moreover, the conventional monitoring device for ordinary automobile tires has a problem that its configuration is complicated.

本発明は、上記問題点を除去し、磁気浮上式車両の支持車輪タイヤのパンクを信頼度を損なうことなく簡単な構造による安価なシステムで検出することができる磁気浮上式車両の支持車輪タイヤのパンク検知装置を提供することを目的とする。   The present invention eliminates the above-mentioned problems, and provides a support wheel tire for a magnetic levitation vehicle that can detect a puncture of a support wheel tire for a magnetic levitation vehicle with a simple system without impairing reliability. An object is to provide a puncture detection device.
