しかしながら、上記した従来の電機子１１１の場合、レール１０５，１０６と対向していない面に磁束が漏れてしまうと、その磁束はブレーキ力として作用しないため、無駄になってしまう。結果的に変換器容量の増大や、鉄心の飽和を引き起こすことになる。   However, in the case of the above-described conventional armature 111, if the magnetic flux leaks to a surface that does not face the rails 105 and 106, the magnetic flux does not act as a braking force and is wasted. As a result, the converter capacity increases and the iron core is saturated.

本発明は、上記状況に鑑みて、渦電流ブレーキ装置の電機子の環状巻コイルの中心線がレールと平行に配置されるとともに、前記渦電流ブレーキ装置の電機子の鉄芯のレール対向面以外の部分であって、側面鉄板及び上面鉄板が前記電機子の鉄芯の両側面及び上面に配置することにより、ブレーキ力の増大を図り得る鉄道車両に装備される渦電流ブレーキ装置を提供することを目的とする。 In view of the above situation, the present invention is such that the center line of the annular winding coil of the armature of the eddy current brake device is arranged in parallel with the rail, and other than the rail facing surface of the iron core of the armature of the eddy current brake device. And providing an eddy current brake device mounted on a railway vehicle capable of increasing the braking force by arranging the side iron plate and the upper iron plate on both sides and the upper surface of the iron core of the armature. With the goal.

本発明は、上記目的を達成するために、
〔１〕鉄道車両に装備される渦電流ブレーキ装置において、前記渦電流ブレーキ装置の電機子の環状巻コイルの中心線がレールと平行に配置されるとともに、前記渦電流ブレーキ装置の電機子の鉄芯のレール対向面以外の部分であって、側面鉄板及び上面鉄板が前記電機子の鉄芯の両側面及び上面に配置されることを特徴とする。 In order to achieve the above object, the present invention provides
[1] In the eddy current brake device installed in a railway vehicle, the center line of the annular coil of the armature of the eddy current brake device is arranged in parallel to the rail, and the armature iron of the eddy current brake device A portion of the core other than the rail-facing surface, wherein the side iron plate and the upper iron plate are disposed on both side surfaces and the upper surface of the iron core of the armature.

本発明によれば、鉄道車両に装備される渦電流ブレーキ装置において、前記渦電流ブレーキ装置の電機子の環状巻コイルの中心線がレールと平行に配置されるとともに、前記渦電流ブレーキ装置の電機子の鉄芯のレール対向面以外の部分であって、側面鉄板及び上面鉄板が前記電機子の鉄芯の両側面及び上面に配置されるようにしたので、前記電機子の環状巻コイルによって生成される磁束の一部による渦電流が前記側面鉄板及び上面鉄板に生じ、その渦電流に起因したブレーキ力が増大する。 According to the present invention, in the eddy current brake device installed in a railway vehicle, the center line of the annular coil of the armature of the eddy current brake device is arranged in parallel with the rail, and the electric machine of the eddy current brake device It is a part other than the rail facing surface of the iron core of the child, and the side iron plate and the upper iron plate are arranged on both side surfaces and the upper surface of the iron core of the armature, so generated by the annular winding coil of the armature An eddy current due to a part of the generated magnetic flux is generated in the side iron plate and the upper iron plate, and the braking force due to the eddy current is increased.

なお、通常のリニア誘導モータの場合は、鉄心に渦電流が流れると、発熱損失が発生し、モータ効率が低下するが、渦電流ブレーキ装置の場合は、その損失分もブレーキエネルギーの消費に寄与するため問題がない。   In the case of a normal linear induction motor, if an eddy current flows through the iron core, a heat loss occurs and the motor efficiency decreases, but in the case of an eddy current brake device, the loss also contributes to the consumption of brake energy. So there is no problem.
