Abstract

軸方向にコンパクトな自動変速機のクラッチユニットを提供する。 それぞれ油圧サーボ２０、４０及びキャンセル油室２８、４８を有する第３のクラッチＣ３と第４のクラッチＣ４とを、軸方向にオーバラップして径方向の異なる位置に配置する。第３のクラッチＣ３のキャンセル油室２８を構成するキャンセルプレート２５は、第４のクラッチＣ４のクラッチドラムの段差部５３に嵌合していると共に、該第４のクラッチＣ４のキャンセル油室４８を構成するキャンセルプレート４５はスナップリング３０によって抜止め配置されている。第３のクラッチＣ３のキャンセル油室２８に配設されるリターンスプリング２６は、第４のクラッチＣ４のキャンセル油室４８に配設されるリターンスプリング４６と比して付勢力が大きいため、第４のクラッチＣ４のクラッチドラム４２は、常にスナップリング５０に当接して位置決めされる。
