装置
　本発明は、装置に関する。
　ＪＰ２０１５－２１１５４３Ａには、冷媒流路管を用いて回転電機に冷却油等を供給する回転電機の冷却構造が開示されている。
　ＪＰ２０１５－２１１５４３Ａに開示される構造では、冷媒流路管の供給口側をステータの外周よりも突出させることで、冷媒流路管に冷却油等の液体を供給できるようにしている。そのため、回転電機を含む装置全体の小型化を図ることが難しいという問題がある。
　本発明は、このような技術的課題に鑑みてなされたもので、回転電機に液体を供給する構造を備えた装置の小型化を図ることを目的とする。
　本発明のある態様によれば、回転電機と、前記回転電機へ液体を供給する液体供給部材と、前記液体供給部材を介して前記回転電機と軸方向に対向する対向部材と、を備え、前記液体供給部材には、前記対向部材を介して液体が供給される、装置が提供される。

　以下、添付図面を参照しながら、本発明の実施形態に係る装置としての動力伝達装置１０を備えたハイブリッド車両（以下、単に「車両」という。）１００について説明する。

　クラッチ４８は、ノーマルオープンの油圧式クラッチである。クラッチ４８は、油圧コントロールバルブユニット（図示せず）によって調圧された油圧により、締結・解放が制御される。なお、本実施形態では、クラッチ４８は湿式多板式クラッチであるが、他のクラッチを用いてもよい。
　クラッチ４８が締結されると、入力軸１１とロータ８０とが直結する。すなわち、入力軸１１と回転軸４４とが直結して同速回転する。
　回転センサ４７は、回転電機４０の回転速度及び角度（位相）の少なくとも一方を検知するセンサである。本実施形態では、回転センサ４７はホールセンサであって、ロータ８０に固定された保持部材４９には、回転センサ４７の被検出部としてのマグネット５２が取り付けられている。

　前後進切換え機構３０は、ダブルピニオン遊星歯車組３０ａを主たる構成要素とし、そのサンギヤは回転電機４０の回転軸４４に結合され、キャリアはバリエータ２０のプライマリプーリ２に結合される。前後進切換え機構３０は、さらに、ダブルピニオン遊星歯車組３０ａのサンギヤおよびキャリア間を直結する前進クラッチ３０ｂ、及びリングギヤを固定する後進ブレーキ３０ｃを備える。そして、前進クラッチ３０ｂの締結時には、回転軸４４からの入力回転がそのままの回転方向でプライマリプーリ２に伝達され、後進ブレーキ３０ｃの締結時には、回転軸４４からの入力回転が逆転されてプライマリプーリ２へと伝達される。

　これら可動円錐板２ｂ、３ｂは、油圧コントロールバルブユニットからプライマリプーリ圧及びセカンダリプーリ圧を供給することにより固定円錐板２ａ、３ａに向けて付勢され、これによりベルト４を円錐板に摩擦係合させてプライマリプーリ２及びセカンダリプーリ３間での動力伝達を行う。
　変速に際しては、目標変速比に対応させて発生させたプライマリプーリ圧及びセカンダリプーリ圧間の差圧により両プーリ２、３のＶ溝の幅を変化させ、プーリ２、３に対するベルト４の巻き掛け円弧径を連続的に変化させることで目標変速比を実現する。
　回転電機４０と前後進切換え機構３０との間には、液体供給部材としての弧状のパイプ５３と、前後進切換え機構３０の回転電機４０側を覆い、パイプ５３を介して回転電機４０と軸方向に対向する対向部材としての中間カバー３１と、が設けられる。
　中間カバー３１には、ブッシュ５４を介してスプロケット５５が回転自在に支持されている。スプロケット５５は、接続部材５６を介して回転電機４０の回転軸４４と接続されており、スプロケット５５はさらに、オイルポンプ６の入力軸６ａに設けられたスプロケット６ｂとチェーン５７で連結されている。これにより、回転電機４０が回転すると、オイルポンプ６が駆動されて油圧コントロールバルブユニットにオイルが供給される。
　図２は、中間カバー３１、パイプ５３、及びチェーン５７を回転電機４０側から見た図である。図３は、ハウジング４１及びパイプ５３の斜視図である。
　図２、図３に示すように、パイプ５３は、上方に凸となる曲線状に回転電機４０の周方向に沿って延伸し、下方に切欠き部５３ｂを有する。図２に示すように、パイプ５３の回転電機４０側の側面には、複数の孔５３ａが設けられる。なお、パイプ５３の形状は、上方に凸となる曲線状であればよく、例えば、円弧状、楕円弧状等とすることができる。
　パイプ５３には複数のクランプ３４が取り付けられている。パイプ５３は、これら複数のクランプ３４を中間カバー３１と共締めしてケース１２に固定される。
　パイプ５３は、中間カバー３１の内部に設けられた油路３１ｃと中間部材３２を介して接続されており（図４参照）、中間カバー３１から供給された液体としてのオイルを複数の孔５３ａから回転電機４０に向けて噴出させるようになっている。なお、中間部材３２については後で詳しく説明する。
　ハウジング４１における中間カバー３１と対向する面には、図３に示すように、周方向に沿って複数の孔４１ｃが形成されており、パイプ５３の複数の孔５３ａから噴出したオイルが、複数の孔４１ｃを通ってステータ４３のコイルに直接吹き付けられる。これにより、回転電機４０に上方からオイルを供給でき、回転電機４０を効率よく冷却することができる。なお、孔４１ｃの形状及び数は適宜変更可能である。
　このように、本実施形態では、回転電機４０と軸方向に対向する中間カバー３１を介してパイプ５３にオイルを供給できるので、軸方向から見て回転電機４０の外周側へのパイプ５３のはみ出しを抑制できる。よって、動力伝達装置１０を小型化することができる。なお、軸方向から見て回転電機４０の外周からパイプ５３がはみ出さないようにすることも可能であり、動力伝達装置１０の小型化の観点からはより好ましいと言える。
　また、中間カバー３１から中間部材３２を介してパイプ５３にオイルを供給する構成とすることで、中間部材３２によって油路の向きを変えることができる。言い換えると、中間部材３２は、第１油路と、第１油路と交差する第２油路と、を少なくとも有するということになる。そのため、例えば、パイプ５３を途中で折り曲げるような必要がなくシンプルな形状にできる等、各種部材の設計自由度を高めることができる。そして、各種部材の設計自由度が高まることで、動力伝達装置１０の小型化が容易となる。
　また、本実施形態では、ブッシュ５４、スプロケット５５、及びチェーン５７は、図１に示すように、径方向においてパイプ５３とオーバーラップする位置に設けられ、チェーン５７は、図２に示すように、弧状のパイプ５３の内周側からパイプ５３の切欠き部５３ｂを通ってパイプ５３の外周側へ延びるように配置される。「径方向にオーバーラップする」とは、径方向から見たときに少なくとも一部が重なるように配置されることを意味する。
　上述したように、パイプ５３は、回転電機４０の上方側にオイルを供給する。そのため、パイプ５３を周方向全周に設ける必要はない。つまり、パイプ５３の切欠き部５３ｂを大きくすることができる。これにより、切欠き部５３ｂを経由するようにチェーン５７を配置することが可能となり、パイプ５３の内周側にチェーン５７の一部及びスプロケット５５等を配置できる。よって、動力伝達装置１０全体のサイズを抑制できる。
　また、中間カバー３１は、図２に示すように、パイプ５３に沿って設けられる弧状のリブ３１ａを有し、ハウジング４１は、図３に示すように、パイプ５３に沿って設けられる弧状のリブ４１ｄを有する。
　中間カバー３１のリブ３１ａとハウジング４１のリブ４１ｄとは、回転電機４０をケース１２に組み付けた状態において、リブ４１ｄの内側にリブ３１ａが嵌合するようになっている。これにより、リブ３１ａ及びリブ４１ｄは、チェーン５７を囲うようにしてパイプ５３とチェーン５７との間を隔てる隔壁部３５を構成する（図５参照）。
　これによれば、パイプ５３やハウジング４１から流れ落ちるオイルがチェーン５７に付着することを防止でき、オイルの攪拌抵抗によりチェーン５７の駆動効率が低下することを防止できる。
　車両１００は以上のように構成され、運転モードとして、バッテリから供給される電力によって回転電機４０を駆動して回転電機４０のみの駆動力によって走行するＥＶモードと、エンジン１のみの駆動力によって走行するエンジン走行モードと、エンジン１の駆動力と回転電機４０の駆動力とによって走行するＨＥＶモードと、を有する。
　ＥＶモードでは、車両１００は、クラッチ４８を解放し、前進クラッチ３０ｂ及び後進ブレーキ３０ｃのいずれか一方を締結した状態で、バッテリからの電力によって回転電機４０のみを駆動して走行する。
　エンジン走行モードでは、車両１００は、クラッチ４８と、前進クラッチ３０ｂ及び後進ブレーキ３０ｃのいずれか一方と、を締結した状態で、エンジン１のみを駆動して走行する。
　ＨＥＶモードでは、車両１００は、クラッチ４８と、前進クラッチ３０ｂ及び後進ブレーキ３０ｃのいずれか一方と、を締結した状態で、エンジン１と回転電機４０とを駆動して走行する。
　続いて、図４を参照しながら、中間部材３２について詳しく説明する。図４は、図２におけるＩＶ－ＩＶ断面図である。
　中間部材３２は、中間カバー３１の表面と当接する規制部３２ａと、規制部３２ａと隣接しシールリング３３を保持するシールリング溝３２ｂと、シールリング溝３２ｂと隣接するフランジ状の先端部３２ｃと、パイプ５３が挿入されるパイプ穴３２ｄと、一端がパイプ穴３２ｄの底面に開口する第１油路としての油路３２ｅと、一端側が油路３２ｅと連通し他端が先端部３２ｃの端面に開口する第２油路としての油路３２ｆと、を有する。
　パイプ５３は、パイプ穴３２ｄに挿入されており、例えば、ロウ付けや溶接等で中間部材３２に固定される。また、パイプ５３は、パイプ穴３２ｄに圧入で固定することもできる。シールリング３３は、例えば、Ｏリング等である。
　中間部材３２は、中間カバー３１に挿入されている。具体的には、中間部材３２は、中間カバー３１に設けられた収容孔３１ｂに先端部３２ｃを挿入した状態で、中間カバー３１と共締めしてケース１２に固定される。
　中間部材３２を中間カバー３１に取り付けた状態では、図４に示すように、規制部３２ａが中間カバー３１の表面と当接し、先端部３２ｃが収容孔３１ｂに収容される位置になる。「先端部３２ｃが収容孔３１ｂに収容されている」とは、先端部３２ｃの少なくとも一部が収容孔３１ｂに収まっていることを意味する。これにより、収容孔３１ｂの内壁と当接する位置にシールリング３３が保持されるので、中間カバー３１と中間部材３２との間のシール性を確保できる。
　例えば、中間カバー３１に座ぐりを設けること等によりシールリング３３を保持することも考えられるが、その場合は、シールリング３３を保持する構成の軸方向の長さが大きくなる。よって、結果的に、中間カバー３１の軸方向の長さ、すなわち厚みが大きくなることになる。これに対して、中間部材３２にシールリング３３を保持する先端部３２ｃを設けることで、中間カバー３１の厚みを小さくすることができる。
　また、本実施形態では、中間カバー３１の収容孔３１ｂにおけるシールリング３３が当接するシール面３１ｄは、中間部材３２側に向けて拡がるテーパ状になっている。つまり、シール面３１ｄは傾斜面になっている。
　シールリング３３の取付性の観点から、収容孔３１ｂの入口部分に傾斜面を設けることが考えられる。しかしながら、入口部分のみを傾斜面にした場合は、傾斜面とシール面との間に境界が存在することになり、シールリング３３を取り付ける際にシールリング３３が傷つくことが考えられる。そのため、図４に示すように、入口部分だけでなく、入口部分からシールリング３３が当接する部分までの全体を傾斜面とすることが好ましい。
　続いて、図５を参照しながら、回転電機４０の構成について詳しく説明する。図５は、回転電機４０の断面図である。
　ハウジング４１は、外周側に設けられた筒状部４１ａと、内周側に設けられてハウジング４１の内側に向かって延びる筒状部４１ｂと、複数の孔４１ｃと、リブ４１ｄと、を有する。
　筒状部４１ａの内周には、ステータ４３が固定される。筒状部４１ｂは、ベアリング５１を介して回転軸４４を回転自在に支持する。
　リブ４１ｄは、中間カバー３１のリブ３１ａと共に、パイプ５３とチェーン５７との間を隔てる隔壁部３５を構成する。
　複数の孔４１ｃは、ハウジング４１におけるパイプ５３と対向する面に形成されている。これにより、矢印で示すように、パイプ５３の複数の孔５３ａから噴出したオイルが、複数の孔４１ｃを通ってステータ４３のコイルに直接吹き付けられる。
　カバー４２は、外周側が動力伝達装置１０のケース１２に固定される。また、カバー４２は、内周側に設けられてハウジング４１側に向かって延びる筒状部４２ａを有する。
　筒状部４２ａの外周には、回転センサ４７が収容されたホルダ５８が固定される。また、筒状部４２ａは、ベアリング５０を介して入力軸１１を回転自在に支持する。
　ホルダ５８は、内部に回転センサ４７を保持する環状部５８ａと、環状部５８ａから径方向に延びる支持部５８ｂと、支持部５８ｂの先端に設けられた変換部５８ｃと、を有する。
　回転センサ４７と接続された電線７０は、フィルム状部分７０ａと、ケーブル７０ｂと、を有する。フィルム状部分７０ａとケーブル７０ｂとは、変換部５８ｃ内で結線されている。
　フィルム状部分７０ａは、支持部５８ｂに固定されたフレキシブルプリント基板７０ｃ上に設けられる。
　ホルダ５８は、環状部５８ａにカバー４２の筒状部４２ａを挿入してカバー４２に取り付けられる。
　これにより、ホルダ５８は、ロータ８０や保持部材４９等の回転体と軸方向に隣接して設けられる。「軸方向に隣接」とは、２つの部材が他の部材を介さず軸方向に隣り合って配置されていることを意味し、２つの部材が接触していてもよいし、隙間をあけて配置されていてもよい。
　筒状部４２ａの外周におけるホルダ５８よりも先端側には、溝に固定されたリング７１が環状部５８ａと軸方向にオーバーラップして設けられる。「軸方向にオーバーラップする」とは、軸方向から見たときに少なくとも一部が重なるように配置されることを意味する。そのため、ホルダ５８は、筒状部４２ａの先端側への移動がリング７１によって規制される。これにより、筒状部４２ａからホルダ５８が脱落することを防止できる。
　また、カバー４２には、筒状部４２ａの基端部から径方向に延びる溝４２ｂが形成されている。ホルダ５８の支持部５８ｂはカバー４２の内壁に沿うように形成されており、ホルダ５８をカバー４２に取り付けると支持部５８ｂが溝４２ｂに嵌まった状態となる。このように、径方向に延びる溝４２ｂに径方向に延びる支持部５８ｂを収容することで、ホルダ５８の周方向への回転を規制できる。また、これによれば、カバー４２に溝４２ｂを設けない場合と比較して、軸方向におけるカバー４２とロータ８０や保持部材４９等の回転体との距離を近づけることができる。
　なお、回転体は、回転物であれば限定されない。例えば、回転センサ４７の被検出部であるマグネット５２の保持部材４９、クラッチ４８、回転電機４０のロータ８０等は回転体である。
　筒状部４２ａと入力軸１１との間には、外部へのオイルの漏出を防止するためのシール部材５９が設けられる。
　入力軸１１と回転軸４４との間には、軸方向の荷重を受けるニードルベアリング６０と径方向の荷重を受けるニードルベアリング６１と、が設けられる。
　入力軸１１における前後進切換え機構３０側の端部には、クラッチハブ６２が溶接で固定される。クラッチハブ６２は、外周側に設けられてエンジン１側に向かって延びる筒状部６２ａを有する。筒状部６２ａの外周には、スプライン結合によって軸方向に摺動自在にクラッチ４８の複数のドライブプレート４８ａが取り付けられる。
　回転軸４４の外周には、ロータフレーム８１が溶接で固定される。ロータフレーム８１は、外周側に設けられた筒状部８１ａを有する。筒状部８１ａの外周には、コア８２が固定される。
　筒状部８１ａの内周には、スプライン結合によって軸方向に摺動自在にクラッチ４８の複数のドリブンプレート４８ｂが取り付けられる。リテーナプレート６３は、ピストンアーム６４とは反対側の端部に配置されたドリブンプレート４８ｂと、筒状部８１ａの内周の溝に固定されたリング６５との間に介装される。リテーナプレート６３は、軸方向の厚みがドリブンプレート４８ｂより厚く、ドライブプレート４８ａ及びドリブンプレート４８ｂの倒れを防止する。
　油圧コントロールバルブユニットからピストン油室６６に締結圧が供給されると、ピストン６７がリターンスプリング６８を圧縮しながらエンジン１側に向けて移動する。クラッチ４８は、ニードルベアリング６９及びピストンアーム６４を介してピストン６７から伝達される押圧力によって締結状態となる。
　なお、ニードルベアリング６９は、ピストン６７がピストンアーム６４の回転に伴って連れ回ることを抑制している。
　また、ロータフレーム８１には、マグネット５２を保持する保持部材４９が取り付けられる。
　保持部材４９は、外周側に設けられた圧入部４９ａによって筒状部８１ａの外周側に圧入で固定されている。なお、保持部材４９は、例えば、リテーナプレート６３に圧入や溶接で固定するように構成してもよい。
　また、保持部材４９は、内周側に設けられて前後進切換え機構３０側に向かって延びる筒状部４９ｂを有する。筒状部４９ｂは、径方向におけるクラッチハブ６２とホルダ５８に保持された回転センサ４７との間に位置しており、内周にマグネット５２が取り付けられる。なお、マグネット５２は、保持部材４９を設けることなく、他の回転体に保持されるように構成してもよい。
　以上述べたように、本実施形態の動力伝達装置１０は、回転電機４０と、回転電機４０へオイルを供給するパイプ５３と、パイプ５３を介して回転電機４０と軸方向に対向する中間カバー３１と、を備え、パイプ５３には、中間カバー３１を介してオイルが供給される。
　これによれば、回転電機４０と軸方向に対向する中間カバー３１を介してパイプ５３にオイルを供給できるので、軸方向から見て回転電機４０の外周側へのパイプ５３のはみ出しを抑制できる。よって、動力伝達装置１０を小型化することができる。
　また、動力伝達装置１０は、中間カバー３１に接続される中間部材３２を備え、パイプ５３は、中間部材３２に接続される。
　このように、中間カバー３１から中間部材３２を介してパイプ５３にオイルを供給する構成とすることで、中間部材３２によって油路の向きを変えることができる。言い換えると、中間部材３２は、第１油路と、第１油路と交差する第２油路と、を少なくとも有するということになる。そのため、例えば、パイプ５３を途中で折り曲げるような必要がなくシンプルな形状にできる等、各種部材の設計自由度を高めることができる。そして、各種部材の設計自由度が高まることで、動力伝達装置１０の小型化が容易となる。
　また、動力伝達装置１０は、中間カバー３１と中間部材３２との間をシールするシールリング３３を備え、中間部材３２は、中間カバー３１の表面と当接する規制部３２ａと、規制部３２ａと隣接しシールリング３３を保持するシールリング溝３２ｂと、シールリング溝３２ｂと隣接する先端部３２ｃと、を有し、中間カバー３１は、シールリング３３を収容する収容孔３１ｂを有し、先端部３２ｃは、収容孔３１ｂに収容されている。
　例えば、中間カバー３１に座ぐりを設けること等によりシールリング３３を保持することも考えられるが、その場合は、シールリング３３を保持する構成の軸方向の長さが大きくなる。よって、結果的に、中間カバー３１の軸方向の長さ、すなわち厚みが大きくなることになる。これに対して、中間部材３２にシールリング３３を保持する先端部３２ｃを設けることで、中間カバー３１の厚みを小さくすることができる。
　また、収容孔３１ｂの内壁におけるシールリング３３と当接するシール面３１ｄは傾斜面である。
　これによれば、収容孔３１ｂの入口部分だけでなく、シールリング３３が当接するシール面３１ｄまでの全体が傾斜面となるので、シールリング３３を取り付ける際にシールリング３３に傷がつくことを防止できる。
　また、パイプ５３は弧状であって、動力伝達装置１０は、パイプ５３の内周側からパイプ５３の切欠き部５３ｂを経由してパイプ５３の外周側へ延びるチェーン５７を備える。
　パイプ５３を周方向全周に設ける必要はないので、パイプ５３の切欠き部５３ｂを大きくすることができる。これにより、切欠き部５３ｂを経由するようにチェーン５７を配置することが可能となり、パイプ５３の内周側にチェーン５７の一部及びスプロケット５５等を配置できる。よって、動力伝達装置１０全体のサイズを抑制できる。
　また、動力伝達装置１０は、パイプ５３とチェーン５７との間にチェーン５７を囲うように設けられた隔壁部３５を備える。
　これによれば、パイプ５３やハウジング４１から流れ落ちるオイルがチェーン５７に付着することを防止でき、オイルの攪拌抵抗によりチェーン５７の駆動効率が低下することを防止できる。
　以上、本発明の実施形態について説明したが、上記実施形態は本発明の適用例の一つを示したものに過ぎず、本発明の技術的範囲を上記実施形態の具体的構成に限定する趣旨ではない。
