Description
トルコンタイプの発進方式の自動変速機であって、ロックアップクラッチを付加させたものにおいては、連結位置と非連結位置との間を移動可能とされたロックアップクラッチの如き比較的複雑且つ大型な構成をトルクコンバータ内の流体雰囲気中に形成させなければならず、トルクコンバータが大型化してしまうとともに当該トルクコンバータ内のレイアウトの自由度が著しく抑制されてしまうという問題があった。
また更に、クラッチ手段は、同一筐体内に前記第1クラッチ手段、第2クラッチ手段、及び当該第1クラッチ手段及び第2クラッチ手段に対応する2つの油圧ピストンを有するとともに、当該油圧ピストンを作動させる油圧を制御することにより、当該第1クラッチ手段又は第2クラッチ手段を任意選択的に作動可能とされたので、動力伝達装置全体を更に簡素化及び小型化することができる。
本実施形態に係る動力伝達装置は、自動車(車両)のエンジン(駆動源)による駆動力を車輪(駆動輪)に伝達又は遮断するためのものであり、図1、図2及び図5に示すように、トルクコンバータ1と、クラッチ手段3と、選択手段4と、第1駆動シャフト5と、第2駆動シャフト6と、ダンパ機構7と、第3クラッチ手段8とを主に有している。尚、図1は、本実施形態に係る動力伝達装置の主要部を表す縦断面図であり、図2、5は、同実施形態に係る動力伝達装置を模式化した模式図を示すものである。
