（産業上の利用分野）
本発明は主として鉄道車両に使用される弾性車輪の改良
に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates primarily to improvements in elastic wheels used in railway vehicles.
（従来の技術）
従来から、鉄道車両用の車輪にはタイヤ部と輪 １心

向の弾性で、また車軸直角方向の変位を弾性体３の圧縮
方向の弾性で抑制するように構成し、振動を吸収するも
のである。(Prior art) Conventionally, wheels for railway vehicles have been divided into a tire part and a wheel core part, and an elastic body such as rubber is interposed between the two parts.
An elastic wheel aiming at soundproofing and vibration-proofing effects is well known, and its structure includes an elastic body 3 with an initial pressure tank provided between the rim part of the wheel center 1 and the tire 2, as shown in FIG. Seshime,
It absorbs vibrations by suppressing displacement in the axle direction that occurs during wheel shifting by the elasticity in the shearing direction of the elastic body 3, and suppressing displacement in the direction perpendicular to the axle axis by the elasticity in the compression direction of the elastic body 3.
（発明が解決しようとする問題点）
ところが、この形式の弾性車輪は、ディスクブレーキを
採用している車両には使用可能であるが、踏面ブレーキ
を採用している車両には前記弾性体３の耐熱温度が問題
となり適用が極めて困難である。(Problems to be Solved by the Invention) However, although this type of elastic wheel can be used for vehicles that employ disc brakes, it is necessary to use the elastic body 3 for vehicles that employ tread brakes. It is extremely difficult to apply due to the problem of heat resistance.
すなわち、踏面ブレーキは周知の通り車輪の転動面（踏

高熱が熱伝導により、車輪踏面から輪心に向かって伝導
してゆき、弾性体３の特性に影響を与えるからである。In other words, as is well known, tread brakes obtain the required braking force by pressing brake shoes made of a material such as cast iron or resin against the rolling surface (tread) of a wheel.
In recent years, railway vehicles have become faster and faster, and when the brakes are applied, the temperature of the wheel tread reaches a red-hot state of several hundred degrees, and this high heat is conducted from the wheel tread to the wheel core by heat conduction, and the elastic body 3 This is because it affects the characteristics of
従って、第４図に示すような従来の弾性車輪の構成では
タイヤ２と弾性体３が直接接触しているために前記の車

年の特性変化が著しく短期間での保守を必要とするため
、大多数の鉄道車両には使用されζいないのが現状であ
る。Therefore, in the configuration of a conventional elastic wheel as shown in FIG. At present, the elastic body 3 is not used in most railway vehicles because its characteristics change significantly over time and require maintenance in a short period of time.
本山別人が前記の弾性車輪を試作して特性試験を行ない
、適用の可否を調査した結果でも、鉄道車両においては
、ディスクブレーキを採用した車両と低速で走行する市
電紙の車両には採用できることが確認されている。Betsuto Motoyama made a prototype of the elastic wheel mentioned above, conducted a characteristic test, and investigated its applicability, but the results showed that it could be used for railway vehicles equipped with disc brakes and streetcars that run at low speeds. Confirmed.
しかしながら欧米諸国の鉄道車両には、ディスクブレー

弾性車輪の形式でも問題なく使用されているが、国内の
鉄道車両においてはディスクブレーキは踏面ブレーキに
比べ重量増、コスト高等の問題がある為、一部の車両に
限定して使用されてはいるが、従来から大多数の鉄道車
両は踏面ブレーキを採用しているのが現状である。However, disc brakes are often used in railway vehicles in Western countries, and the elastic wheel type described above can be used without any problems, but in domestic railway vehicles, disc brakes are replaced by tread brakes. Due to the problems of increased weight and high cost, the majority of railway vehicles have traditionally used tread brakes, although their use is limited to some vehicles.
また鉄道車両は寿命が長く昭和初期に製造された車両が
現在依然として使用されており、この鉄道車両のブレー
キ装置を踏面ブレーキからディスクブレーキに改造する
のは台車全体の構造に係わるため、改造不可能である。In addition, railway vehicles have a long lifespan, and vehicles manufactured in the early Showa period are still in use today, and it is impossible to modify the brake system of these railway vehicles from tread brakes to disc brakes because it involves the structure of the entire bogie. It is.
本発明は上記した問題点を解決するためになされたもの
で、主として鉄道車両において踏面ブレーキを採用して
