【発明の属する技術分野】
この発明は、自動車の自動変速機（ＡＴ）用トルクコンバ−タのステ−タに装着される一方向クラッチと軸受との組立体、特に部品点数や組立工数を低減し且つニ−ドルロ−ラベアリングも取り込んだステ−タ組立体（ステ−タＡＳＳ’Ｙ）とすることができる一方向クラッチと軸受との組立体に関する。
【０００２】
【従来の技術】
自動車の自動変速機（ＡＴ）用トルクコンバ−タでは、エンジンより取り出した動力でポンプインペラを駆動し、ステ−タを介してＡＴ用オイル（自動変速機油）によりタ−ビンランナを回転駆動する。前記ステ−タには一方向クラッチが装着されており、前記ポンプインペラと同方向には回転するが逆方向には回転不可としてある。そして一方向クラッチにはステ−タの羽根角度によりアキシャル荷重がかかるのでこれを吸収させるため両側或いは片側にスラストベアリングが配置されている。
【０００３】
図６は、従来のステ−タＡＳＳ’Ｙの縦断面図である。この図に示すように、ステ−タ１のボス部１ａには一方向クラッチを構成する外輪２と内輪３とが配置され、更に、これら外・内輪の間の環状空間１１には係合部材のスプラグ４が配置される。そして前記外輪２及び内輪３の側面には前記環状空間１１を密封状態とするベアリングサポ−ト５が固定され、該ベアリングサポ−ト５の外側にはスラストニ−ドルロ−ラベアリング１６が装着される。
【０００４】
【発明が解決しようとする課題】
従来のステ−タ１の側面に使用されるスラストニ−ドルロ−ラベアリング１６は、レ−ス１８とニ−ドルロ−ラ１７と保持器１９とより構成されるが、一方向クラッチを組み込んだステ−タＡＳＳ’Ｙとは別体である。該スラストニ−ドルロ−ラベアリング１６は、組み込み時ベアリングサポ−ト５のボス部５ａに前記レ−ス１８の円筒部１８ｂを嵌め込み、また、ベアリングサポ−ト５もスナップリング１５でステ−タ１のボス部１ａに固定するようになっている。従って、トルクコンバ−タの組み込み時にはスラストニ−ドルロ−ラベアリング１６やベアリングサポ−ト５等の組立作業は別工程となりしかも煩雑な作業となっている。
【０００５】
この発明は上記する課題に着目してなされたものであり、部品点数及び組立工数を低減し、ステ−タＡＳＳ’Ｙの幅をスリムとし、且つスラストニ−ドルロ−ラベアリングも取り込んだステ−タＡＳＳ’Ｙとすることのできる一方向クラッチと軸受との組立体を提供することを目的としている。
【０００６】
【課題を解決するための手段】
即ち、この発明は上記する課題を解決するために、▲１▼ステ−タのボス部内径側に外輪を固定すると共に該外輪との間に一定の環状空間を形成するよう固定軸若しくは固定軸に固定した内輪を配置し、前記環状空間に係合部材を配置して一方向クラッチを構成し、更にベアリングサポ−トを前記環状空間を密封するようステ−タボス部に固定すると共に、該ベアリングサポ−ト外側にレ−スとニ−ドルロ−ラと保持器とで構成されるスラストニ−ドルロ−ラベアリングを装着してなる一方向クラッチと軸受との組立体において、前記ステ−タのボス部外周端部に溝を形成し、前記レ−スの径をステ−タのボス部の径とほぼ同程度の径とすると共に、該レ−スの外周には取付部を設け、該取付部を前記ボス部の溝に係止させることを特徴とする。
【０００７】
或いは、▲２▼ステ−タのボス部内径側に外輪を固定すると共に該外輪との間に一定の環状空間を形成するよう固定軸若しくは固定軸に固定した内輪を配置し、前記環状空間に係合部材を配置して一方向クラッチを構成し、更にベアリングサポ−トを前記環状空間を密封するようステ−タボス部に固定すると共に、該ベアリングサポ−ト外側にレ−スとニ−ドルロ−ラと保持器とで構成されるスラストニ−ドルロ−ラベアリングを装着してなる一方向クラッチと軸受との組立体において、前記ステ−タのボス部外周端部に溝を形成し、前記レ−スの径をステ−タのボス部の径とほぼ同程度の径とすると共に、該レ−スの外周には取付部を設け、また該レ−ス内周側には前記ベアリングサポ−トのボス部に嵌合させるための円筒部を形成し、該円筒部と前記保持器とをかしめて一体とし、該レ−スに設けた取付部を前記ボス部に形成した溝に係止させることを特徴とする。
【０００８】
【発明の実施の形態】
以下、この発明の具体的実施の形態について図面を参照しながら説明する。
尚、従来と同一の構成要素には重複記載を避けるために同一の符号を用いて説明する。図１はこの発明の一方向クラッチと軸受との組立体を備えたステ−タＡＳＳ’Ｙの縦断面図である。ステ−タ１は、図示しないポンプインペラとタ−ビンランナとの間に配置されるが、ボス部１ａ内径には外輪２が固定して配置され、一定の環状空間４を形成するよう内輪３が配置される。この場合、前記外輪２はステ−タ１が合成樹脂製の場合射出成形時に一体に固定され、金属製の場合はスプライン嵌合等により一体に固定して配置される。また、内輪３は図示しない固定軸にスプライン嵌合等により固定される。前記外輪２と内輪３との間の環状空間１１にはスプラグ４や該スプラグ４を保持するための保持器及びスプラグをロック方向に付勢するためのばね等が配置され一方向クラッチを構成する。この一方向クラッチの構造は従来周知である。そして該環状空間１１は、ステ−タ１のボス部１ａに嵌め込むようにして取り付けるベアリングサポ−ト５により密封される。
【０００９】
図２はスラストニ−ドルロ−ラベアリング６の縦断面図であり、図３はステ−タ１とスラストニ−ドルロ−ラベアリング６の一部拡大縦断面図である。
ベアリングサポ−ト５の外側にはスラストニ−ドルロ−ラベアリング６が装着されるが、該スラストニ−ドルロ−ラベアリング６は、レ−ス８とニ−ドルロ−ラ７と保持器９とで構成される。
前記ステ−タ１のボス部１ａの外周端部には溝１０が設けられている。また、前記レ−ス８は、図からも判るように、その径をステ−タ１のボス部１ａの径とほぼ同程度の径とし、更に、該レ−ス８には外周数箇所（実施例では４箇所）取付部８ａが設けられている。該取付部８ａはステ−タ１のボス部１ａに設けた溝部１０に係止させるためのものであって、ニ−ドルロ−ラ７を保持させた保持器９を前記レ−ス８に組み込み一体としたものを、該レ−ス８を前記ステ−タ１のボス部１ａに当てて押し込めば取付部８ａが溝部１０にパチンと嵌まって一体に固定される。この場合、ステ−タ１のボス部１ａの内径側には従来のようなスナップリング１５（図６参照）を固定するための溝及び幅を設ける必要がないからその分ステ−タ１はスリムになる。また、上記説明のようにスラストニ−ドルロ−ラベアリング６の取り付けが極めて簡単となる。
【００１０】
図４は前記スラストニ−ドルロ−ラベアリング６の平面図、図５は図４のＡ−Ａ矢視断面図である。
前記レ−ス８には、内周側に前記ベアリングサポ−ト５のボス部５ａを嵌合させるための円筒部８ｂが形成されている。また、前記保持器９は、平面状の板で製作され、一定半径の周方向所定間隔に多数のポケット９ａ，９ａ，・・・を設けてあり該ポケット９ａ、９ａ，・・・にニ−ドルロ−ラ７を嵌め入れるようになっている。
【００１１】
次に、前記レ−ス８と保持器９とは一体とするが、この場合、該レ−ス８の内径側に形成した円筒部８ｂにニ−ドルロ−ラ７を保持した保持器９の内径側の穴９ｂを嵌め入れ、該円筒部８ｂの数箇所（図では３箇所）をかしめることによりレ−ス８と保持器９とを一体とする。即ち、スラストニ−ドルロ−ラベアリング６のレ−ス８に保持器９を固定し、更に、該レ−ス８にスナップリングと同様のベアリングサポ−ト５を固定する機能を持たせてかしめて一体としてある。
【００１２】
この発明の一方向クラッチと軸受との組立体は以上のような構成からなり、スラストニ−ドルロ−ラベアリング６のレ−ス８は、ステ−タ１のボス部１ａに取り付けられたベアリングサポ−ト５の外側から該ベアリングサポ−ト５を固定する状態でステ−タ１のボス部１ａの溝１０にその取付部８ａを嵌め込み固定される。従って、従来のようにベアリングサポ−ト５をステ−タ１に固定するためのスナップリング１５（図６参照）は不要となり、また取り付け作業も容易となる。更に、スラストニ−ドルロ−ラベアリング６は、レ−ス８と保持器９とが一体となっているため組み込み時の取り扱いが極めて容易となる。
【００１３】
尚、図１に示すように、ステ−タ１のボス部１ａのもう一方の側には径方向内側にベアリングサポ−トとなる鍔部１ｂが延設してあるが、かかる鍔部１ｂを設けることなく前記ベアリングサポ−ト５を嵌め込み、両側にスラストニ−ドルロ−ラベアリング６を固定するようにしても良い。
【００１４】
【発明の効果】
以上詳述したようにこの発明の一方向クラッチと軸受との組立体によれば、スナップリング等の部品が不要となるため部品点数を減らし且つ加工組立工数を低減することができる。また、ステ−タにスナップリングを固定するための溝及び幅を設ける必要がないからその分ステ−タＡＳＳ’Ｙはスリムになる。
更に、ニ−ドルロ−ラベアリングはレ−スとニ−ドルロ−ラを保持するリテ−ナワッシャとを一体としたので、ニ−ドルロ−ラベアリングも一体に取り込んだステ−タＡＳＳ’Ｙとすることができる。その結果、トルクコンバ−タの組み込みが容易となり作業効率も大幅に向上させることができる。
