Description

  The present invention relates to a puncture detection device for supporting wheel tires of a magnetically levitated vehicle.

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.

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.

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.

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).

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.

  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.

In order to achieve the above object, the present invention provides
[1] In a puncture detection device for a supporting wheel tire of a magnetically levitated vehicle,
A supporting wheel tire, a circumscribing auxiliary wheel provided on a side surface of the supporting wheel tire , a radio transmitter including a power source, a transmitting unit, and a transmitting antenna disposed on a side surface of the circumscribing auxiliary wheel, and a head surface portion of the circumscribing auxiliary wheel A wiring for connecting the power source and the transmission unit disposed in the radio, and a radio receiver for receiving radio waves from the radio transmitter when the wiring is healthy , and the supporting wheel tire is punctured. and, by contact with the circumscribed auxiliary wheel head surface portion running road surface, the the wire is disconnected, wherein the benzalkonium be reported that the a puncture of the support wheel tires with a possible signal is interrupted from the wireless receiver And

  ADVANTAGE OF THE INVENTION According to this invention, the puncture detection apparatus of the support wheel tire of a magnetic levitation type vehicle can be provided with a simple structure and a reliable and inexpensive system.

A puncture detection device for a support wheel tire of a magnetically levitated vehicle according to the present invention includes a support wheel tire, a circumscribed auxiliary wheel provided on a side surface of the support wheel tire , a power source and a transmission unit disposed on a side surface of the circumscribed auxiliary wheel. And a radio transmitter comprising a transmission antenna, a wiring connecting the power source and the transmission unit disposed on the head surface of the circumscribed auxiliary wheel , and a radio wave from the radio transmitter when the wiring is sound When the wiring is disconnected due to the support wheel tire being punctured and the head surface portion of the circumscribed auxiliary wheel being in contact with the road surface, the signal from the wireless receiver is interrupted. with a function indicating that a puncture of the support wheel tires.

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a schematic diagram of a puncture detection device for supporting wheel tires of a magnetically levitated vehicle according to the present invention, FIG. 2 is a schematic diagram showing an arrangement state of the radio transmitter, and FIG. 3 is a block diagram of the radio transmitter.
