Abstract
Description
図1は、本発明の一実施形態としてのロックアップ装置が採用されたトルクコンバータ1の断面部分図である。図1の左側にはエンジン(図示せず)が配置され、図の右側にトランスミッション(図示せず)が配置されている。図1に示すO-Oは、トルクコンバータ及びロックアップ装置の回転軸線である。図2は図1の拡大部分図であり、図3はロックアップ装置の正面図である。
図1~図3に示すように、ロックアップ装置7は、タービン22とフロントカバー11との間の空間9に配置されており、必要に応じて両者を機械的に連結するための機構である。ロックアップ装置7は、空間9を、フロントカバー11とロックアップ装置7との間の第1油圧室Aと、ロックアップ装置7とタービン22との間の第2油圧室Bと、に分割している。
エンジン始動直後には、第1ポート17及び第3ポート19からトルクコンバータ本体5内に作動油が供給され、第2ポート18から作動油が排出される。第1ポート17から供給された作動油は第1油圧室Aを外周側に流れ、第2油圧室Bを通過して流体作動室6内に流れ込む。このため、第1油圧室Aと第2油圧室Bとの油圧差によってピストン71はトランスミッション側に移動している。すなわち摩擦フェーシング76はフロントカバー11から離れ、ロックアップが解除されている。このロックアップ解除時には、フロントカバー11からのトルクは作動油を介してタービン22に伝達される。
トルクコンバータ1の速度比が上がり、入力シャフトが一定の回転数に達すると、第1ポート17から第1油圧室Aの作動油が排出される。この結果、第1油圧室Aと第2油圧室Bとの油圧差によって、ピストン71がフロントカバー11側に移動させられ、摩擦フェーシング76がフロントカバー11の摩擦面に押し付けられる。この結果、フロントカバー11のトルクは、ピストン71から、ドライブプレート72及びトーションスプリング74を介してドリブンプレート73に伝達される。さらに、トルクは、ドリブンプレート73からタービン22に伝達される。すなわち、フロントカバー11が機械的にタービン22に連結され、フロントカバー11のトルクがタービン22を介して直接入力シャフトに出力される。
この装置では、ドライブプレート72の受け部72cが、トーションスプリング74の中心よりエンジン側においてトーションスプリング74の内周側を支持している。このため、トーションスプリング74が圧縮されて変形した際に、受け部72cによってトーションスプリングの中心部内周側が確実に支持され、トーションスプリング74が内周側に落ち込むのが防止される。
本発明は以上のような実施形態に限定されるものではなく、本発明の範囲を逸脱することなく種々の変形又は修正が可能である。
