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。
ロックアップ装置4は、タービン6とフロントカバー2との間に配置されており、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4は、図1及び図2に示すように、ピストン30と、ドライブプレート31と、ドリブンプレート32と、複数のトーションスプリング33と、複数の振り子ユニット34と、複数のストッパ35(図3及び図4参照)と、を有している。図2は、図1におけるロックアップ装置4の部分を抽出して示したものである。
ピストン30は、クラッチの連結及び遮断を行うための部材であり、中心孔が形成された円板形状である。ピストン30の内周縁には、軸方向トランスミッション側に延びる内周側筒状部30aが形成されている。内周側筒状部30aはタービンハブ18のエンジン側の外周面によって回転方向及び軸方向に移動可能に支持されている。なお、ピストン30は、タービンハブ18のトランスミッション側の面に当接することで、軸方向トランスミッション側への移動が規制されている。
ドライブプレート31は、円板状の部材であり、内周部に固定部31aを有し、外周部に複数の係合部31bを有している。固定部31aはリベット39によってピストン30に固定されている。また、複数の係合部31bは、ドライブプレート31の外周部の一部をタービン6側に折り曲げて形成されている。各係合部31bはトーションスプリング33の円周方向の端面に当接可能である。
ドリブンプレート32は、円板状の部材であり、内周部に固定部32aを有し、外周部に複数の係合部32bを有している。固定部32aは、タービンシェル16とともにリベット20によってタービンハブ18に固定されている。また、複数の係合部32bは、ドリブンプレート32の外周の一部をさらに外周に突出して形成し、この突出部をフロントカバー2側に折り曲げて形成されている。各係合部32bはトーションスプリング33の円周方向の端面に当接可能である。
複数のトーションスプリング33は、図1及び図2に示すように、ピストン30、ドライブプレート31、及びドリブンプレート32によって支持されている。そして、トーションスプリング33は、ドライブプレート31によって、軸方向及び径方向の移動が規制されている。
複数の振り子ユニット34は、それぞれ対応するガイド溝部40に支持されており、ドリブンプレート32の回転時にガイド溝部40に沿って揺動することにより振動を減衰するものである。
複数のストッパ35は、樹脂製の弾性部材であり、図3及び図4に示すように、ドリブンプレート32に固定されている。なお、図4は図3のIV-O線断面図である。
エンジン回転数が低回転数領域では、ピストン30の軸方向両側の作動油の圧力差によって、ピストン30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38はフロントカバー2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2からのトルクはインペラ5から作動油を介してタービン6に伝達される。
(1)振り子ユニット34の揺動範囲がストッパ35によって規制されるので、振り子ユニット34の軸受43がドリブンプレート32の溝32cの端部に衝突するのを避けることができる。したがって、ドリブンプレート32の異常摩耗や損傷及び軸受43の損傷を防止できる。
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。
