本発明は、電気車両用たわみ板継手に備えたクラッチ装置に関するものである。
【0002】
【従来の技術】
一般に、通常のたわみ板継手は、車両台車部の主電動機と歯車装置の間に設置されており、軸ばねより上方に装荷されている主電動機と、軸ばねの下方に装荷されている歯車装置との変位差を吸収し、主電動機の動力を歯車装置を介して車輪に伝え、車両を走行又は停止させている。(例えば特許文献1参照)
この状態を図6(a)、図6(b)、図7により説明する。
図6(a)、図6(b)、図7はその従来の一例を示す説明図であり、図6(a)はその平面図、図6(b)は側面図、図7はたわみ板継手であり、1は主電動機、2はたわみ板継手、3は歯車装置、4は台車、5は車輪である。
図6(a)、(b)、図7において、電車の走行中および停車時には、乗客数の変動による荷重の変動や走行中の振動により主電動機1と歯車装置3の間には相対的に変位が生じ、たわみ板継手2は、たわみ板2cのばね効果によりその変位を吸収し、主電動機1の駆動力を、歯車装置3を介して車輪5に伝え、車両を走行及び停止させている。
図7において、たわみ板継手は、主電動機側固定継手2fと主電動機側中間継手2a、および歯車装置側固定継手2gと歯車装置側中間継手2bがそれぞれたわみ板2cを介して固定継手−中間継手締鋲材2dで密に固定されており、また、主電動機側中間継手2aと歯車装置側中間継手2bについても中間継手締鋲材2dで密に固定されている。

しかしながら、このような手段では、次のような課題があった。
永久磁石式同期電動機方式の主電動機は、主電動機固定子巻線の層間短絡故障時に車輪から与えられる回転によって制御不能な大きな短絡電流と大トルクが発生し、その大トルクによって主電動機と結合されている歯車装置等の機械装置を破壊する危険性がある。また、その大きな短絡電流により主電動機が焼損する危険性もある。これは、歯車装置と主電動機間のたわみ板継手の結合がボルト、ナットで機械的に密に結合しているためである。これを解消するためには、主電動機と歯車装置間の機械的結合を開放し、短絡電流およびトルクを発生させない機構が必要となる。
本発明は、上述した点に鑑みて創案されたもので、その目的とするところは、これらの課題を解消し、主電動機と歯車装置間の機械的に密な結合を開放する手段として、電気車両用たわみ板継手の中間継手間にクラッチ装置を提供することにある。

【0007】
3.請求項3において、
前記棒の外周にばねを入れ、前記中間継手を引っ張った状態または押し付けた状態として中間継手間を分離又は接合した状態とし、車両の乗務員室又は客室から電気的又は機械的に指令を与えることによって前記電磁アクチュエータ又は電磁石を駆動し、任意に中間継手間を接合および開放することができる請求項1から請求項2記載のクラッチ装置付き電気車両用たわみ板継手である。
【0008】
4.請求項4において、

【0014】
図1(b)において、車両の乗務員室または客室から電気的又は機械的に指令を与えることにより、主電動機軸端に取り付けられたスリップリング1bから電磁アクチュエータ7に給電が開始され、電磁アクチュエータ7は棒8を図1(b)の右方向に動かし、ばね6の引っ張り力に打ち勝つことによりクラッチは接合され、この状態で、主電動機1と歯車装置3は結合される。
また、ばね6を主電動機側中間継手2aを押す方向に設置して主電動機側と歯車装置側の中間継手2a、2bを常時結合させておき、電磁アクチュエータ7を棒8を引っ張る方向に動作させることにより開放する方法も考えられる。
図1(a)、(b)において、主電動機1と歯車装置3の間に生じる変位により、あらゆる方向に外力を受けるため、緩衝ゴム10によりその外力を吸収する。
また、緩衝ゴム10の代わりに、棒8に自在継手を用いる方法も考えられる。

【0018】
図5(a)、(b)は、本発明のクラッチ装置付き電気車両用たわみ板継手の第5実施形態を示す図である。
図5(a)は、前記クラッチ板9又は歯車12を角度をつけて配置した実施例であり、鋭角側が歯車装置側であるが、主電動機側を鋭角側にすることも考えられる。
図5(b)は、主電動機側中間継手2aを凹形に、歯車装置側中間継手を凸形に配置した実施例であり、この凹凸の関係についても、主電動機側中間継手2aを凸形に、歯車装置側中間継手2bを凹形とすることも考えられる。
それ以外は図1(b)と同様であるが、この第5実施形態は、前記の実施形態第1から第4に対し、主電動機1と歯車装置3の変位が大きくなった場合のクラッチの結合度を高めることができる。
【0019】
第6実施形態として、図示はしていないが、前記の実施形態第1から第5に対し、クラッチ装置を歯車装置3側、または主電動機1と歯車装置3の両側に設置する場合もある。
