Abstract
Description
以下では、制御部40による制御について説明する。制御部40は、第1クラッチ10または第2クラッチ20の作動、および、各シンクロ機構の作動を制御することで、自動変速機1における変速動作を制御する。より具体的には、自動変速機1は、例えば第1シンクロ機構61を作動させる際には、シフトフォーク(不図示)を移動させる油圧アクチュエータ(不図示)を制御することで第1シンクロスリーブ61bを移動させ、第1ドグギヤ61cまたは第2ドグギヤ61dと係合させることで、第1入力軸31と第3入力側ギヤ53aまたは第4入力側ギヤ54aとを選択的に同期結合させる。制御部40は、シフト位置検出部41が検出したシフト位置に基づいてシンクロ機構を制御して、所望の回転軸と所望のギヤとを結合させることで、自動変速機1を所望の変速段へと切り替える。
以下では、本発明の実施の形態に係る自動変速機1において、図2で説明した制御部40の制御によって生じる効果について具体的に説明する。
第1の例として、発進段として第1速段が用いられる場合について説明する。
第2の例として、発進段として第3速段が用いられる場合について説明する。
第3の例として、発進段として第2速段が用いられる場合について説明する。図6は、第2速段における駆動力伝達経路を示す模式図である。図6に示す第2速段では、第2クラッチ20が接続状態とされ、第4シンクロ機構64によって第2出力側ギヤ56aと出力軸35とが結合される。
本発明の実施の形態に係る自動変速機1は、駆動力を出力する出力軸35を含む複数の回転軸と、出力軸35に設けられた出力側ギヤ(第1出力側ギヤ55a、第2出力側ギヤ56a、第3出力側ギヤ57a)を含む複数のギヤと、出力軸35と出力側ギヤとを結合させる出力側シンクロ機構(第2シンクロ機構62、第4シンクロ機構64)を含む複数のシンクロ機構と、ニュートラル位置およびパーキング位置を含む複数のシフト位置のいずれが選択されたかを検出するシフト位置検出部41、および、シフト位置検出部41においてニュートラル位置またはパーキング位置が検出された場合に、出力側シンクロ機構以外のシンクロ機構(第1シンクロ機構61および/または第3シンクロ機構63)を作動させて、出力軸以外の回転軸と出力側ギヤ以外のギヤとを結合させる制御部40と、を備える。
以上、図面を参照しながら各種の実施形態について説明したが、本開示はかかる例に限定されない。当業者であれば、特許請求の範囲に記載された範囲内において、各種の変更例または修正例に想到しうることは明らかであり、それらについても当然に本開示の技術的範囲に属するものと了解される。また、開示の趣旨を逸脱しない範囲において、上記実施の形態における各構成要素は任意に組み合わせられてもよい。
