Description

車両用駆動装置
 この技術は、例えばハイブリッド車両等の車両に搭載される車両用駆動装置に係り、詳しくは、クラッチの外周側に回転電機のロータが配置される車両用駆動装置に関する。
 近年、内燃エンジンとモータ・ジェネレータ(以下、単に「モータ」という)とを動力源として組合せたハイブリッド車両の開発が進められている。このようなハイブリッド車両に用いられるハイブリッド駆動装置の一形態として、一般的な自動変速機の発進装置(例えばトルクコンバータ等)の部分に、変速機構の入力軸に駆動連結された回転電機(モータ・ジェネレータ)と、内燃エンジンに駆動連結されるエンジン連結軸と該入力軸とを係脱(係合又は解放)するエンジン接続用クラッチと、を配置して、簡易な置換でパラレル式のハイブリッド車用駆動装置を構成するものが提案されている(特許文献1参照)。
 このようなハイブリッド車用駆動装置にあって、コンパクト化のために、エンジン接続用クラッチの一部がロータの内周側に軸方向に重なる位置に配置され、そのクラッチドラムが、ロータを支持するロータ支持部材の内周側にスプライン係合するように構成されたものもある(特許文献1の図6参照)。
特開2004-1708号公報
 ところで、上記特許文献1の図6に示すようなハイブリッド車用駆動装置にあっては、エンジン接続用クラッチを冷却するため、内周側の回転軸(変速機構の入力軸)から当該クラッチの摩擦板に油を供給するように構成されている。この摩擦板を冷却した油は、クラッチドラムに形成した貫通孔から外周側に排出することが求められるが、ロータ支持部材がクラッチドラムの外周側を塞ぐ形となっているため、油の排出性が良好でないという問題がある。
 クラッチドラム内部の油の排出性が良好でないと、クラッチの摩擦板の冷却性も良好でなくなるため、摩擦板に貼付けする摩擦材を高温に耐え得るものにする必要があるが、そのような摩擦材を用いると、コストアップを招いてしまうという問題がある。また、摩擦材のコストアップを防ぐためには、クラッチドラムの外周側を空けるように配置することが考えられるが、その場合は、モータとクラッチとを軸方向にオフセットして配置することになり、軸方向のコンパクト化の妨げになるという問題が生じる。
 そこで、ロータが複数の摩擦板に径方向から視て軸方向に少なくとも一部が重なるように配置され、かつクラッチドラムとロータ支持部材とがスプライン係合する構造にあって、摩擦板を冷却した油の排出性の向上を図ることが可能な車両用駆動装置を提供することを目的とするものである。
 本車両用駆動装置(1)は(例えば図1及び図2参照)、複数の摩擦板(17,19)と、それら摩擦板(17,19)を押圧する油圧サーボ(40)と、前記複数の摩擦板(17,19)及び前記油圧サーボ(40)を内包すると共に、径方向から視て前記複数の摩擦板(17,19)と軸方向に重なる位置に複数の貫通孔(42c)が貫通形成されたクラッチドラム(50)と、を有し、前記複数の摩擦板(17,19)と内周側から油を供給することにより前記複数の摩擦板(17,19)を冷却し、前記複数の摩擦板(17,19)から外側に通過した油が前記複数の貫通孔(42c)から前記クラッチドラム(50)の外側に排出されるクラッチ(K0)と、
 ステータ(5)と、前記複数の摩擦板(17,19)に径方向から視て軸方向に少なくとも一部が重なるように配置されたロータ(4)と、を有する回転電機(3)と、
 前記ロータ(4)の内周側を覆うと共に、内周側にて前記クラッチドラム(50)にスプライン係合するドラム状のドラム部(51b)を有し、前記ロータ(4)を支持するロータ支持部材(51)と、を備え、
 前記ロータ支持部材(51)のドラム部(51b)は、内周側に、軸方向の端部から前記複数の貫通孔(42c)に対向する部分を溝形状に形成した複数の溝部(51f)を有することを特徴とする。
 これにより、ロータ支持部材のドラム部が、内周側に、軸方向の端部からクラッチドラムの複数の貫通孔に対向する部分を溝形状に形成した溝部を有しているので、クラッチドラムの複数の貫通孔から溝部の溝形状を通って油を円滑に排出させることができ、油の排出性を良好にすることができる。これにより、クラッチドラムの内部に油が溜まることを防止でき、冷却性を良好にできるため、摩擦材のコストアップを招くことなく、軸方向のコンパクト性も維持することができる。また、ロータ支持部材のドラム部の内周側にあって、例えば全周に亘って隙間を形成すると、ドラム部の剛性が低下する虞があるが、溝部を形成しただけであるので、ドラム部の剛性の低下も防止することができる。

 以下、本実施の形態に係るハイブリッド駆動装置(車両用駆動装置)1を図1及び図2に沿って説明する。なお、本実施の形態に係るハイブリッド駆動装置1は、FF(フロントエンジン・フロントドライブ)タイプの車両に搭載されて好適なものであり、図中における左右方向は実際の車両搭載状態における左右方向に対応するが、説明の便宜上、エンジン等の駆動源側を「前方側」、駆動源とは反対側を「後方側」というものとする。
 [ハイブリッド駆動装置の概略構成]
 図1に示すように、ハイブリッド車両(以下、単に「車両」という)100は、駆動源として、内燃エンジン2の他に、回転電機(モータ・ジェネレータ)3を有しており、この車両100のパワートレーンを構成するハイブリッド駆動装置1は、内燃エンジン2と車輪6との間の動力の伝達経路L上に設けられる変速機構7と、該変速機構7と内燃エンジン2との間に配置され、内燃エンジン2からの動力が入力される入力部9と、内燃エンジン2の脈動を吸収しつつ入力部9と該内燃エンジン2とを接続する接続部14と、を有して構成されている。
 上記接続部14には、内燃エンジン2のクランク軸2aにドライブプレート11を介して接続されるダンパ12が備えられており(図2参照)、該ダンパ12は、入力部9としての入力部材でもあるエンジン連結軸(エンジン連結軸部材)13に接続されている。つまりエンジン連結軸13は、ダンパ12を介して内燃エンジン2に駆動連結されていることになる。
 上記入力部9は、エンジン連結軸13と変速機構7の入力軸15との間の動力伝達を断接するクラッチ(エンジン接続用クラッチ)K0と、クラッチドラム50に駆動連結されたモータ・ジェネレータ(回転電機)3と、を備えて構成されている。該モータ・ジェネレータ(以下、単に「モータ」という)3は、該クラッチドラム50に連結された中空円柱状のロータ4と、該ロータ4の径方向外側に対向配置された中空円柱状のステータ5と、を有して構成されている。
 また、上記クラッチK0は、中空円板状の複数の内摩擦板(摩擦板)17及び外摩擦板(摩擦板)19がクラッチドラム50に内包された多板クラッチによって構成されており、このクラッチドラム50は、上記変速機構7の入力軸15と一体に回転するように連結されている。即ち、クラッチK0は、上記伝達経路Lの内燃エンジン側の伝達経路Lに駆動連結される内摩擦板17と、車輪側の伝達経路Lに駆動連結される外摩擦板19とを有していると共に、上記クラッチドラム50も車輪側の伝達経路Lに駆動連結されている。
 変速機構7は、例えば複数の摩擦係合要素(クラッチやブレーキ)の係合状態に基づき伝達経路を変更して前進6速段及び後進段を達成し得る変速機構からなる。変速機構7の出力部材は、ディファレンシャル装置Dを介して駆動車輪6に接続されている。なお、変速機構7としては、例えば前進3~5速段や前進7速段以上を達成する有段変速機構であってもよく、また、ベルト式無段変速機、トロイダル式無段変速機、コーンリング式無段変速機などの無段変速機構であってもよく、つまりどのような変速機構であっても本発明を適用し得る。
 以上のように、ハイブリッド駆動装置1は、内燃エンジン2側から車輪6側に向かって、接続部14、クラッチK0及びモータ3を有する入力部9、変速機構7が順次配置されており、内燃エンジン2及びモータ3の両方を駆動させて車両を走行させる場合には、制御部(不図示)によって油圧制御装置(不図示)を制御してクラッチK0を係合させ、車輪側の伝達経路Lに駆動連結されたモータ3の駆動力だけで走行するEV走行時には、クラッチK0を解放して、内燃エンジン2側の伝達経路Lと車輪6側の伝達経路Lとを切り離すようになっている。
 [入力部の構成]
 ついで、入力部9の構成について図2に沿って詳細に説明する。図2に示すように、変速機構7を収納するミッションケース(不図示)に固定されたハウジングケース26の内部には、クラッチK0及びモータ3が収納されており、これらクラッチK0及びモータ3が収納されたハウジングケース26の内包空間は、該ハウジングケース26に一体に取り付けられた隔壁27によって上記接続部14と仕切られ、閉空間を構成している。
 また、上記ハウジングケース26の中心側には、上記接続部14のダンパ12を介して内燃エンジン2に接続されるエンジン連結軸13と、変速機構7の入力軸15と、が軸心を一致するようにして配置されており、このエンジン連結軸13は、上記隔壁27に対して回転自在に支持されている。また、一方の入力軸15は、ミッションケース(不図示)に固定された隔壁24に回転自在に支持されている。
 上記エンジン連結軸13の変速機構7側である後端部には、クラッチK0の複数の内摩擦板17がスプライン部49sにてスプライン係合するクラッチハブ49が固着されている。つまり内摩擦板17は、エンジン連結軸13に駆動連結されている。また、このクラッチハブ49の先端内周側には内周側から供給される油を溜めるための突起部49bが形成されており、スプライン部49sの谷部の底部分(最内周部分)には、溜めた油を内摩擦板17及び外摩擦板19に供給するための複数の油孔49aが形成されている。なお、これら油孔49aは、周方向の異なる位相にそれぞれ形成されていると共に、それぞれが軸方向に少しずつズレた位置となるように配置されている。これら油孔49aは、図示を省略したが、本実施の形態では軸方向の例えば4箇所にズレるように配置され、それぞれが後述の4枚の外摩擦板19に対応する位置となるように配置されている。
 クラッチK0は、大まかに、上記複数(例えば4枚)の内摩擦板17と、それら内摩擦板17と交互に配置される複数(例えば4枚)の外摩擦板19と、それら内摩擦板17と外摩擦板19とを押圧することでクラッチK0の係合状態を自在に変化させる油圧サーボ40と、これら内摩擦板17、外摩擦板19、及び油圧サーボ40を内包するクラッチドラム50と、を有して構成されている。
 クラッチドラム50は、その油圧シリンダを構成すると共に入力軸15に駆動連結されたシリンダ部材41と、該シリンダ部材41の外周側に固着されたドラム部材42と、が一体に固着されることで構成されている。このドラム部材42は、ドラム状に形成されたドラム部42aとフランジ状に延びるフランジ部42bとを有している。ドラム部42aにはスプライン形状となるスプライン部(第1スプライン部)42sが形成されており、スプライン部42sの内周側には上記複数の外摩擦板19がスプライン係合されていると共に、スナップリング20によりそれら外摩擦板19が抜け止めされている。つまり外摩擦板19は、ドラム部材42及びシリンダ部材41を介して入力軸15に駆動連結されている。また、ドラム部材42のドラム部42aには、内摩擦板17及び外摩擦板19と径方向から視て軸方向に重なる位置にあって、スプライン部42sの谷部の底部分(最外周部分)に、複数の貫通孔42cが貫通形成されている。
 油圧サーボ40は、上記シリンダ部材41に対して軸方向に移動自在に配置されると共に先端部が外摩擦板19(又は内摩擦板17)に対向配置されるピストン43と、シリンダ部材41に対してスナップリング48で位置決めされたリターンプレート44と、これらピストン43及びリターンプレート44との間に縮設されたリターンスプリング45と、を有しており、シリンダ部材41及びドラム部材42とピストン43との間に作動油室46を形成すると共に、ピストン43とリターンプレート44との間に遠心油圧をキャンセルするためのキャンセル油室47が形成されている。
 一方、クラッチK0の外周側にあって、ハウジングケース26の内周側にはモータ3のステータ5が固定されている。該ステータ5は、ステータコア5aと、該ステータコア5aに巻回されたコイルの折り返し部分であって、該ステータコア5aの軸方向両側に突出したコイルエンド5b,5bとを有する形で構成されている。ステータコア5aの内周側には、モータ3のロータ4が所定隙間を存して対向配置されている。このモータ3は、その一部がクラッチK0の外周側に軸方向に重なる位置に配置されており、つまり、ロータ4が内摩擦板17及び外摩擦板19に少なくとも一部が径方向から視て軸方向に重なる位置に配置されている。
 上記ロータ4は、ロータ支持部材51によってハウジングケース26に対して回転自在となるように支持されている。ロータ支持部材51は、軸方向にスリーブ状に延びるスリーブ部51cと、スリーブ部51cに一体的に固定され、該スリーブ部51cから外周方向にフランジ状に延びるフランジ部51aと、フランジ部51aと一体に形成され、該フランジ部51aの外周部分から軸方向にドラム状に延びるように形成されたドラム部51bと、を有して構成されている。
 スリーブ部51cは、アンギュラボールベアリング90と、固定支持部材86とを介して上記隔壁27に対して回転自在となるように支持されている。一方のドラム部51bは、ロータ4のロータコア4aをカシメ部51dと挟持部51eとで挟持しつつ、該カシメ部51dをカシメることにより該ロータコア4aを一体的に固着している。ロータコア4aにはキー部4kが形成されており、キー部4kがドラム部51bのキー溝51kに嵌合することで、ロータコア4aがドラム部51bに回転不能に固定されている。
 また、ドラム部51bの内周側(内周面)には、フランジ部51aが接続された接続部分から軸方向一方側に向けて、上記クラッチドラム50におけるドラム部材42のドラム部42aのスプライン部42sがスプライン係合するスプライン部(第2スプライン部)51sが形成されている。クラッチドラム50とロータ支持部材51とは、このようにスプライン係合により駆動連結するため、ある程度の隙間があるものの、その隙間を存して略々密着する形で近接配置されている。
 そして、ドラム部51bの内周側には、スプライン部51sに対してフランジ部51aとは軸方向反対側(後方側)にあって、軸方向の端部からスプライン部51sの軸方向端部まで上記クラッチドラム50の複数の貫通孔42cに対向する部分を溝形状に形成した複数の溝部51fが形成されている。即ち、この溝部51fは、クラッチドラム50の複数の貫通孔42cがスプライン部42sの谷部の底部分(最外周部分)に形成されており、かつクラッチドラム50とロータ支持部材51との間に相対回転が生じないことから、その溝形状がスプライン部51sにおける谷部と同位相となる位置に周方向に複数箇所形成されている。また、ドラム部51bにおける複数の溝部51fが形成された部分の内周面は、スプライン部51sのスプライン歯の先端の径よりも大きい径に形成されている。この溝部51fは、それぞれの溝形状が軸方向の端部のカシメ部51dの近傍まで形成されているので、油が溝部51fの溝形状に溜まることなく、軸方向の端部から(つまり後方側に)流れるように形成されている。
 ところで、上述のようにロータ支持部材51のドラム部51bのカシメ部51dをカシメるために、ドラム部51bには所定の剛性が必要であり、ドラム部51bの径方向の肉厚がその剛性を維持する厚みに形成されている必要がある。ドラム部51bは、上記キー溝51kが例えば周方向の2箇所に形成されているが、これ以外の部分は肉厚が所定の厚みとなるように構成されている。そして、上記溝部51fは、クラッチドラム50の複数の貫通孔42cに対向する部分のみが溝形状に形成されているので、全周に亘って肉厚を薄くすることなく、つまりドラム部51bの剛性を維持できる構造となっている。また、スプライン部51sのスプライン溝を溝部51fと同じ深さに形成してしまうと、スプライン部51sの強度が低下してしまう虞があるが、本実施の形態では、スプライン部51sのスプライン溝がクラッチドラム50のスプライン部42sにスプライン係合するための深さだけに形成されているので、このスプラインによるトルク伝達を維持しつつ強度も確保されている。
 [潤滑・冷却する油の流れ]
 ついで、クラッチK0を潤滑・冷却する油(潤滑油)の流れについて図2に沿って説明する。変速機構7の入力軸15には、軸方向に油の供給油路a1が形成されている。この供給油路a1には、不図示の油圧制御装置から潤滑圧に基づき隔壁24内部の油路を介して油が供給される。供給油路a1の軸方向端部(前方側)には、外周面に向かって径方向に径方向油路a2が貫通形成されており、供給油路a1の油は、径方向油路a2から上記シリンダ部材41の内周側の空間a3に供給される。
 上記シリンダ部材41の軸方向端部(前方側)には、径方向に貫通油路a4が貫通形成されており、上記シリンダ部材41の内周側の空間a3に溜まった油をクラッチハブ49の内周側に飛散させる。クラッチハブ49には、上述のように内周側に突起部49bにより油溜りが形成されており、貫通油路a4から飛散された油を捕集して溜めると共に、上述の複数の油孔49aから、それぞれ対応する外摩擦板19に向けて油を供給し、それら外摩擦板19や内摩擦板17を潤滑・冷却する。
 上記外摩擦板19や内摩擦板17を通過して、それら外摩擦板19や内摩擦板17を潤滑・冷却した油は、クラッチドラム50におけるドラム部材42のドラム部42aに形成された複数の貫通孔42cから該クラッチドラム50の外周側に排出される。この際、ロータ支持部材51に形成された溝部51fが油の排出を塞ぐことなく、円滑にカシメ部51dの方向に向けて油を排出する。なお、このようにクラッチドラム50の外周側に排出された油は、外摩擦板19や内摩擦板17を潤滑・冷却しているので高温となっており、ステータ5のコイルエンド5bの耐久性を確保するため、該コイルエンド5bに導きたくない。そのため、ハウジングケース26には、コイルエンド5bを覆うカバー部26aが形成されており、クラッチドラム50の外周側に排出された油は、カバー部26aによってコイルエンド5bを迂回して外周方向に導かれ、ハウジングケース26の内壁に沿って下方に流れ、最終的に、ハイブリッド駆動装置1の下方に設けられたオイルパン(不図示)に回収される。
 [本実施の形態のまとめ]
 以上説明したように、本ハイブリッド駆動装置1によると、ロータ支持部材51のドラム部51bが、内周側に、軸方向の端部からクラッチドラム50の複数の貫通孔42cに対向する部分を溝形状に形成してスプライン形状にした溝部51fを有しているので、クラッチドラム50の複数の貫通孔42cから溝部51fを通って油を円滑に排出させることができ、油の排出性を良好にすることができる。これにより、クラッチドラム50の内部に油が溜まることを防止でき、冷却性を良好にできるため、摩擦材のコストアップを招くことなく、軸方向のコンパクト性も維持することができる。また、ロータ支持部材51のドラム部51bの内周側にあって、例えば全周に亘って隙間を形成すると、ドラム部の剛性が低下する虞があるが、溝部51fを形成しただけであるので、ドラム部51bの剛性の低下も防止することができる。
 また、クラッチドラム50は、スプライン部42sを有し、複数の貫通孔42cは、スプライン部42sの外周側に突出した山部に形成され、ドラム部51bの溝部51fのそれぞれが、クラッチドラム50のスプライン部42sにスプライン係合するスプライン部51sにおける谷部と同位相となる位置に形成されているので、ロータ支持部材51のスプライン部51sに影響を与えることなく、溝部51fを形成することを可能とすることができる。
 そして、ドラム部51bは、軸方向の端部をカシメてロータを一体的に固着するカシメ部51dを有しており、ドラム部51bの径方向の肉厚がその剛性を維持する厚みに形成されている必要があるが、クラッチドラム50の複数の貫通孔42cに対向する部分のみが溝部51fとして溝形状に形成されているので、ドラム部51bの剛性を維持したまま、油の排出性を良好にすることができる。
 なお、以上説明した本実施の形態においては、本発明をハイブリッド駆動装置1に適用したものを一例として説明したが、これに限らず、例えば電気自動車に搭載される車両用駆動装置であってもよく、クラッチの外周側に回転電機が配置され、かつクラッチドラムとロータ支持部材とがスプライン係合するものであれば、どのような車両用駆動装置であってもよい。
 また、クラッチドラム50の複数の貫通孔42cは、スプライン部42sの谷部の全ての底部分に形成する方が潤滑油の排出性が良好であり、溝部51fの溝形状も全ての貫通孔42cに対向する位置に形成されている方が排出性が良好であるが、これに限らず、貫通孔42cや溝部51fの溝形状は、その溝形状が貫通孔42cに対向する位置に配置されていれば、所定の間隔ごとに配置されていてもよい。
 また、本実施の形態においては、ロータ4の一部が内摩擦板17及び外摩擦板19に対して軸方向に重なる位置に配置されたものを説明したが、ロータ4が内摩擦板17及び外摩擦板19に対して覆い被さるように重なって配置されていても構わない。また、クラッチの軸方向の向きや、ロータ支持部材に対するクラッチの軸方向の配置は、どのような向きや配置であってもよく、ロータ4の一部又は全部が内摩擦板17及び外摩擦板19に対して軸方向に重なる位置にあるものであればよい。
 本車両用駆動装置は、乗用車、トラック等の車両に用いることが可能であり、特にクラッチと回転電機とが軸方向に少なくとも一部が重なるように配置される構造にあって、クラッチを通過する油の排出性を向上することが求められるものに用いて好適である。
