Abstract
Description
以下、第1の実施形態に係る自動変速機10の油圧制御装置12を、図1乃至図4に沿って説明する。尚、本明細書中で駆動連結とは、互いの回転要素が駆動力を伝達可能に連結された状態を指し、それら回転要素が一体的に回転するように連結された状態、あるいはそれら回転要素がクラッチ等を介して駆動力を伝達可能に連結された状態を含む概念として用いる。
次に、第2の実施形態に係る自動変速機110の油圧制御装置112を、図5及び図6に沿って説明する。本実施形態の自動変速機110は、動力伝達経路bが1本のみである点で、第1の実施形態とは構成を異にしている。このため、第1の実施形態で備えられているシンクロ機構S1や第2のクラッチC2は備えられていない。その他、同様の構成の部分は、符号を同じくして詳細な説明を省略する。
次に、第3の実施形態に係る自動変速機110の油圧制御装置212を、図7に沿って説明する。本実施形態の自動変速機110は、第2の実施形態の自動変速機110と同様の構成であるので、図面を援用して詳細な説明は省略する。
