Description

本発明は、動力アセンブリに関し、具体的に、車両を駆動するか又は電気を発生させるために使用されるエンジンとモータのアセンブリに関する。本発明は、更に、車両駆動装置に関する。
ハイブリッド自動車は、省エネ、排出ガス削減、長続航距離という利点を有し、持続可能な開発に適した電気自動車である。現在、ハイブリッド自動車のエンジンとモータのアセンブリは、ほとんどがエンジンとモータの単純な機械的統合であり、エンジンの後端にフライホイールが接続されており、モータの入力軸がねじり振動ダンパーを介してフライホイールに接続されており、統合度が低い、構成部品が多い、質量が大きい、体積が大きい、信頼性が低い、コストが高い等の欠点が存在する。技術進歩及び量産化の要求に応えることができず、駆動アセンブリの小型化及び軽量化の目標を実現することも困難である。
従来技術における上記問題に鑑みて、本発明は、エンジンとモータとが統合に設けられた構造を採用し、エンジンとモータのアセンブリの統合度を向上させ、エンジンとモータのアセンブリの重量及び体積を効果的に減らしたエンジンとモータのアセンブリを提供する。
本発明は、更に、上記エンジンとモータのアセンブリが設けられた車両駆動装置に関する。
上記目的を達成するために、本発明の技術案は、以下のように実現される。
本発明は、エンジンとモータのアセンブリを提供している。前記エンジンとモータのアセンブリは、エンジンとモータとを含み、前記エンジンの中にクランクシャフトが設けられており、前記クランクシャフトには、前記エンジンの外部に延びた延伸部が設けられており、前記延伸部が前記モータの回転軸を構成し、前記モータのロータが前記延伸部に取り付けられている。
また、前記エンジンが前記モータに隣接して設けられ、前記モータにハウジングが設けられ、前記ハウジングの左端がエンジンのシリンダブロックに直接に取り付けられ、固定面及びシール面を形成し、前記モータには、右エンドカバーがさらに設けられており、前記モータのハウジングが右エンドカバーと一体に形成されているようにしてもよい。
また、前記モータのハウジングは、前記エンジンのシリンダブロックと接続する端にフランジが設けられており、ボルトによって前記エンジンのシリンダブロックと接続され、接続箇所には、シール構造が設けられていてもよい。
また、前記エンジンと前記モータとが隣接する位置には、前記エンジンと前記モータを双方向でシールするダブルオイルシール構造が設けられていてもよい。
また、前記モータの右エンドカバーには、前記モータの回転軸を支持する補助軸受を取り付けるための軸受座が設けられていてもよい。
また、前記モータが、永久磁石モータ、誘導モータ、ハイブリッド励磁モータ、又はスイッチドリラクタンスモータのいずれかであってもよい。
また、前記モータの冷却方式が、油冷、水冷又は空冷のいずれかであり、前記モータのロータと回転軸とが、スプラインを介して接続固定されるか、又は、締まりばめによって接続固定されてもよい。
また、前記モータのハウジング内に油路又は水路が設けられていてもよい。
本発明は、上記に記載のエンジンとモータのアセンブリを含む車両駆動装置をさらに提供しており、前記車両駆動装置が減速機をさらに含み、前記モータの回転軸が前記減速機に接続され、前記減速機が車両伝動軸に接続される。
また、前記車両駆動装置が主駆動モータをさらに含み、前記主駆動モータの回転軸も前記減速機に接続されてもよい。
上記構造を用いて設けられたエンジンとモータのアセンブリは、以下の利点を有する。
本発明では、エンジンとモータとが統合に設けられており、構成部品が少なく、体積が小さく、軽量であり、軸方向の長さが短く、エンジンルームのレイアウトが便利である。
上記構造を用いて設けられた車両駆動装置は、以下の利点を有する。
本発明では、車両駆動装置は、主駆動モータを含んでおり、ハイブリッド自動車に使用可能である。
本発明の実施例１におけるエンジンとモータとの接続構造の模式図である。 本発明の実施例１におけるクランクシャフトの構造模式図である。 本発明の実施例２における車両駆動装置の構造模式図である。
本発明の目的、技術案及び利点が更に明白になるように、以下、図面を参照して、本発明の実施形態をさらに詳しく説明する。
［実施例１］
図１、図２に示すように、本発明の実施例１に係るエンジンとモータのアセンブリは、エンジン８とモータ９とを含み、エンジン８が燃料モードであり、モータ９として、発電機又はＩＳＧモータを用いてもよく、電動機を用いてもよい。
エンジン８には、クランクシャフト７が設けられ、クランクシャフト７には、エンジン８の外部に延びた延伸部７−３が設けられており、延伸部７−３がモータ９の回転軸６を構成し、モータ９のロータ３が延伸部７−３に取り付けられている。
本実施例において、モータ９のロータ３がエンジン８のクランクシャフト７に直接に取り付けられているか、又は、モータ９の回転軸６がエンジン８のクランクシャフト７と一体に形成されているとはいえる。
本実施例において、エンジン８とモータ９とが一体的に統合されており、従来のモータとエンジンとを接続するフライホイールやねじり振動ダンパー等の構造がなく、構成部品が少なく、体積が小さく、軽量であり、構造がコンパクトである。
構成部品及び重量をさらに減らすために、本実施例において、エンジン８がモータ９に隣接して設けられ、モータ９にハウジング２が設けられ、ハウジング２の左端がエンジンのシリンダブロック１に直接に取り付けられ、具体的に、シリンダブロック１の前フランジ面に取り付けられており、固定面及びシール面を形成する。
モータ９には、右エンドカバー１０がさらに設けられており、モータ９のハウジング２が右エンドカバー１０と一体に形成され、このように設計すると、モータ９のハウジング構造を簡素化し、統合度をさらに向上させることができる。
モータ９では、左エンドカバーが取り消されており、これにより、エンジンとモータのアセンブリの軸方向の長さを短縮することもできる。
図１に示すように、モータ９のハウジング２は、エンジン８のシリンダブロック１と接続する端にフランジが設けられており、ボルトによってエンジン８のシリンダブロック１に接続され、エンジン８のシリンダブロック１には、ネジ穴を設ける必要がある。接続箇所には、モータ９のハウジングの内部をシールするためのシール構造、例えばシールリングが設けられている。
エンジン８とモータ９とが隣接する位置には、エンジン８とモータ９を双方向でシールするダブルオイルシール１２という構造が設けられている。ダブルオイルシール１２という構造がエンジン８のシリンダブロック１に設けられてもよく、それに応じて、エンジン８のシリンダブロック１に、シール部品を取り付けるためのシール溝を設ける必要がある。
図２に示すように、クランクシャフト７は、本体７−１と延伸部７−３との間に移行部７−２が設けられており、ダブルオイルシール１２が移行部７−２とシリンダブロック１のシール溝との間の隙間をシールすることにより、エンジン８とモータ９を双方向でシールしている。
図１に示すように、モータ９の右エンドカバー１０には、モータ９の回転軸６を支持する補助軸受５を取り付けるための軸受座が設けられている。ロータ３の半径方向の振れを低減し、モータのエアギャップが大きく変化しないことを保証するために、補助軸受５と回転軸６とが中間ばめ又は締り嵌めを用いる。
エンジン８とモータ９とが隣接する位置において、クランクシャフト７には、すべり軸受１１が設けられており、このすべり軸受１１は、クランクシャフト７と回転軸６とが共有する軸受とみなすことができる。
本実施例において、モータ９は、永久磁石モータ、誘導モータ、ハイブリッド励磁モータ、又はスイッチドリラクタンスモータのいずれであってもよく、モータ９のステータ４が分布巻又は集中巻のいずれを用いてもよい。
モータ９の冷却方式が、油冷、水冷又は空冷のいずれかであり、モータ９のロータと回転軸６とが、例えばスプラインやフラットキーなどのキーを介して接続固定されるか、又は、締まりばめによって接続固定される。図２に示すように、クランクシャフト７には、延伸部７−３にキー溝が設けられている。スプライン接続を用いる場合、延伸部７−３に雄スプラインが、モータ９のロータに雌スプラインが設けられてもよい。
モータ９のハウジング２内に油路又は水路が設けられており、冷却モードが油冷の場合は油路を、冷却モードが水冷の場合は水路を設ける必要がある。
また、放熱効果を向上させるように、モータ９のハウジング２の外側に放熱リブが設けられてもよい。
［実施例２］
図３には、本発明の実施例２が示されており、本実施例において、実施例１に記載のエンジンとモータのアセンブリを含む車両駆動装置であって、主駆動モータ１４をさらに含み、主駆動モータ１４のタイプが電動機である車両駆動装置が提供されている。
車両駆動装置が減速機１６をさらに含み、モータ９の回転軸、主駆動モータ１４の回転軸が共に減速機１６に接続され、減速機１６が車両伝動軸に接続される。エンジンとモータのアセンブリ、主駆動モータ１４のいずれも、個別に、減速機１６を介して車両を駆動することができる。
主駆動モータ１４の回転軸１５がモータ９の回転軸６と同軸に設けられてもよく、このとき、回転軸１５と回転軸６との間にクラッチ１３が設けられている。
好ましくは、クラッチ１３には、電磁クラッチが用いられている。
車両駆動装置は、主駆動モータ１４を備えており、ハイブリッド自動車に使用可能である。車両は、主駆動モータ１４によって単独に駆動されてもよく、エンジン８によって単独に駆動されてもよく、エンジン８と主駆動モータ１４との両方によって駆動されてもよく、また、エンジン８、モータ９、主駆動モータ１４の三者によって駆動されてもよい。
主駆動モータ１４を用いて自動車の走行を駆動する場合、クラッチ１３が切断されてもよいが、エンジン８を用いて自動車の走行を駆動する場合、クラッチ１３を締結する必要がある。
本発明の実施例２におけるエンジンとモータのアセンブリは、他の構造が実施例１と同じであり、ここで繰り返して説明しない。
上記内容は、あくまでも本発明の具体的な実施形態であり、本発明の上記教示の下で、当業者は、上記実施例に基づいて他の改良又は変形を行うことができる。当業者であれば、上記の具体的な記載は本発明の目的をより良く解釈するためのものであり、本発明の保護範囲が特許請求の範囲の保護範囲に基づくものであることが理解されるべきである。
