Description
この種の外部制御式ファン・クラッチ装置としては、例えば回転軸体側に固定した電磁石に通電することにより駆動ディスクに取着された弁部材のアーマチャーを介して作動させて油循環流通路を外部から開閉制御する方式の外部制御式ファン・クラッチ装置があり、その構造は、電磁石のコイルの励磁による磁束を透磁率の高い磁性体からなる回転軸体の磁路を通して板ばねからなる弁部材のアーマチャーに伝え、再び電磁石に戻る磁気回路(磁気ループ)を構成し、電磁石によりクラッチ装置内部の弁部材を作動させてトルク伝達油の流量を制御する方式となしたものである(特許文献1等参照)。
すなわち、弁部材を作動させる電磁石を回転軸体に支持する軸受を介して磁気回路(磁気ループ)を構成しているため、磁気回路が長くなり電磁石の磁力を効率よくアーマチャーに伝達することができず、アーマチャーを吸引するために過剰な電磁力を必要とし、電磁石の寸法、重量が大きくなり、ファン・クラッチ装置の小型、軽量化がはかられない上、消費電力も多く必要となるという問題があった。
すなわち、本発明では電磁石16がON(励磁)の時、前記したように磁気回路は電磁石16、第1磁性体リング18、アーマチャー10−2、回転軸体1及び第2磁性体リング20で構成され、磁束は図2に矢印で示すように電磁石16→第1磁性体リング18→アーマチャー10−2→回転軸体1→第2磁性体リング20の順に流れるので、電磁石16の磁束が効率よく弁部材10のアーマチャー10−2に伝えられ消費電力を低減できるのみならず、電磁石16の小型・軽量化もはかられるという効果が得られる。
