Abstract
Description
たとえば特許文献1の変速機駆動装置では、シフト作動用モータと、セレクト作動用モータという2つのモータが備えられており、これらのモータにより、手動操作と同様の操作を行わせるようにしている。
そこで、本願発明者らは、1つの電動モータを用いて、シフト作動およびセレクト作動の両方を実現させることを検討している。たとえば、電動モータの回転トルクを、シフト作動用のシフト作動部材、およびセレクト作動用のセレクト作動部材の一方に選択的に伝達させるためのクラッチ機構を採用する。クラッチ機構は、シフト作動部材に連結された第1回転体と入力軸とを連結/解放する第1電磁クラッチ、およびセレクト作動部材に連結された第2回転体と入力軸とを連結/解放する第2電磁クラッチを備えている。第1電磁クラッチが励磁状態にあるときは、第2電磁クラッチは無励磁状態とされ、また、第2電磁クラッチが励磁状態にあるときは、第1電磁クラッチは無励磁状態とされる。
この構成によれば、第1ケーシング側係合部と係合可能な第1係合部が、第1回転体に一体回転可能に設けられている。第1電磁コイルの無励磁状態では、この第1係合部は第1ケーシング側係合部に係合する。また、第1電磁コイルの励磁状態では、第1係合部は第1電磁コイルに吸引されて、第1係合部と第1ケーシング側係合部との係合が外れるようになっている。
一方、入力軸と第2回転体とが連結される場合、第1クラッチの第1電磁コイルは無励磁状態にあるので、第1係合部と第1ケーシング側係合部とが係合し、第1回転体がケーシングに連結される。このケーシングへの連結状態では、第1回転体は回転不能である。したがって、入力軸からの解放状態にある第1回転体を回転不能とし、これにより、シフト作動部材またはセレクト作動部材に逆入力があった場合における当該作動部材の変位(移動または回転)を防止することができる。
本発明本発明野の第2の観点においては、前記第1電磁コイルと前記ケーシング側係合部との間において、前記第1回転体に一体回転可能かつ、軸方向に移動可能に配置された磁性リング(55,70)をさらに含み、前記第1係合部は、前記磁性リングに一体移動可能に設けられている、変速機駆動装置であってもよい。
第1電磁コイルの無励磁状態では、磁性リングは第1電磁コイル側に吸引されず、そのため、第1係合部は移動しない。そのため、第1係合部と第1ケーシング側係合部との間で係合状態が保たれている。すなわち、第1回転体がケーシングに連結される。
第1電磁コイルの無励磁状態では、アーマチュアは第1電磁コイル側に吸引されないので、アーマチュアは入力軸と係合しない。また、アーマチュアの吸引がないので第1係合部の移動はなく、第1係合部と第1ケーシング側係合部との係合状態が保たれる。したがって、この状態で、第1回転体は入力軸から解放され、かつケーシングに連結される。
第4の観点として、前記第1係合部は、前記ケーシング側係合部に対して摩擦係合する摩擦部(56)を含むものであってもよい。この場合、摩擦部は、円環状に形成されていてもよい。この構成では、入力軸に対する第1回転体の回転姿勢に拘わらず、第1ケーシング側係合部と第1係合部とが係合することが可能である。そのため、入力軸と第1回転体との連結状態における互いの回転姿勢に制約がない。
また、入力軸と第2回転体とが連結される場合、第2クラッチの第2電磁コイルは励磁状態にあるので、第2係合部と第2ケーシング側係合部との係合は外れている。すなわち、第2回転体がケーシングから解放されている。そのため、入力軸から第2回転体に回転トルクが伝達されると、第2回転体は入力軸とともに一体的に回転する。
変速機2は、公知の平行歯車式変速機(図示せず)であり、乗用車やトラックなどの車両に搭載される。変速機2は、ギヤハウジング4と、ギヤハウジング4内に収容される平行歯車式の変速機構(図示せず)と、この変速機構を駆動するための変速機駆動装置1とを備えている。変速機駆動装置1は、変速機構にシフト動作を行わせるシフトシャフト(シフト作動部材)8と、変速機構にセレクト動作を行わせるセレクトシャフト(セレクト作動部材)12と、シフトシャフト8およびセレクトシャフト12を駆動するための共通の駆動源として用いられる電動アクチュエータ3とを備えている。
前述のように、ケーシング5内には、電動モータ9(図1参照)の回転トルクが入力される入力軸30が収容されている。この入力軸30は、外郭円筒形状をなしており、第1出力軸6および第2出力軸7と同心に配置されている。入力軸30は、軸方向への移動(往復移動)が許容されている。ケーシング5内には、入力軸30を軸方向に挟むように、第1ロータ31および第2ロータ32が収容されている。第1ロータ31は、入力軸30の一方側(図3および図4に示す右側)に配置されている。第2ロータ32は、入力軸30の他方側(図3および図4に示す左側)に配置されている。なお、第1および第2ロータ31,32は、軸方向への移動が許容されていない。
次いで、第1ロータ31および第1クラッチ34について説明する。
第1ロータ31には、第1転がり軸受47および円環状の第1フィールド48(後述する)を介して、入力軸30と同軸に回転可能に支持されている。具体的には、ケーシング5に第1フィールド48が内嵌固定されるとともに、その第1フィールド48の内周に第1転がり軸受47の外輪が内嵌固定されている。第1ロータ31は、外郭略円筒状の本体部80と、本体部80の外周から径方向外方に突出する大径の第1アーマチュアハブ49と、本体部80の外周から径方向外方に突出する大径の第1ブレーキ用ハブ50と、第1出力軸6の端部を支持するための第1ボス51とを備えている。第1アーマチュアハブ49は、軸方向内端(入力軸30側端部。図3および図4で示す左端)に設けられている。第1アーマチュアハブ49は、第1転がり軸受47による支持位置よりも軸方向外側(入力軸30と反対側。図3および図4で示す右側)に設けられている。第1アーマチュアハブ49と第1ブレーキ用ハブ50とはほぼ同じ外径を有している。第1ボス51は、第1ブレーキ用ハブ50の軸方向外側(入力軸30側と反対側。図3および図4で示す右側)に形成されている。第1ボス51に第1出力軸6の端部(図3および図4で示す左端部)が固定的に取り付けられている。
第2ロータ32には、第2転がり軸受62および円環状の第2フィールド63(後述する)を介して、入力軸30と同軸に回転可能に支持されている。具体的には、ケーシング5に第2フィールド63が内嵌固定されるとともに、その第2フィールド63の内周に第2転がり軸受62の外輪が内嵌固定されている。第2ロータ32は、外郭略円筒状の本体部81と、本体部81の外周から径方向外方に突出する大径の第2アーマチュアハブ64と、本体部81の外周から径方向外方に突出する大径の第2ブレーキ用ハブ65と、第2出力軸7の端部を支持するための第2ボス66とを備えている。第2アーマチュアハブ64は、軸方向内端(入力軸30側端部。図3および図4で示す右端)に設けられている。第2アーマチュアハブ64は、第2転がり軸受62による支持位置よりも軸方向外側(入力軸30と反対側。図3および図4で示す左側)に設けられている。第2アーマチュアハブ64と第2ブレーキ用ハブ65とはほぼ同じ外径を有している。第2ボス66は、第2ブレーキ用ハブ65の軸方向外側(入力軸30側と反対側。図3および図4で示す左側)に形成されている。第2ボス66に第2出力軸7の端部(図3および図4で示す右端部)が固定的に取り付けられている。
入力軸30と第1ロータ31との連結時(図3参照)には、第1クラッチ34が連結状態にあり、第2クラッチ35が解放状態にある。このとき、第1電磁コイル36は励磁状態にあり、第2電磁コイル37は無励磁状態にある。
また、第2電磁コイル37の無励磁状態では、第2磁性リング70は第2電磁コイル37側に吸引されず、第2磁性リング70が軸方向に移動しない。そのため、第2磁性リング70に固定された第7フェーシング71と、第8フェーシング75(第2係合リング73)とは係合状態にある。すなわち、入力軸30と第1ロータ31との連結時には、第2ロータ32がケーシング5と連結している。このケーシング5への連結状態では、第2ロータ32はケーシング5によって保持されており、回転不能である。
この状態では、第2アーマチュア45は第2フィールド63に吸引されるが、第1アーマチュア41は第1フィールド48に吸引されない。したがって、第2アーマチュア45および入力軸30が第2フィールド63側に移動する。そして、第2アーマチュア45の一部を構成する第6フェーシング68が、入力軸30に固定された第2フェーシング44と摩擦係合する。これにより、第2アーマチュア45と入力軸30との係合が達成されて、第2出力軸7は入力軸30に連結する。
以上により、この実施形態によれば、第1ロータ31と入力軸30との連結状態では、第2ロータ32がケーシング5に連結される。ケーシング5への連結状態では、第2ロータ32は回転不能である。したがって、第2ロータ32に逆入力があった場合に、シフトシャフト8が回転するのを防止することができる。
また、クラッチ34,35の電磁コイル36,37を用いて、ロータ31,32のケーシング5に対する連結/解放を行う。したがって、ロータ31,32のケーシング5に対する連結/解放のための専用の磁気回路を設ける必要がなく、これにより、コストダウンを図ることができる。
電動アクチュエータ102は、電動モータ103と、電動モータ103の回転トルクを、シフトセレクトシャフト101をその中心軸線C3まわりに回転させる力に変換するためのシフト変換機構104と、電動モータ103の回転トルクを、シフトセレクトシャフト101をその軸方向Y2に移動させる力に変換するためのセレクト変換機構105と、電動モータ103の回転駆動力の伝達先を、シフト変換機構104とセレクト変換機構105との間で切り換えるため切換えユニット106とを備えている。これら電動モータ103、シフト変換機構104、セレクト変換機構105および切換えユニット106は、略筒状のケーシング107内に収容されている。
切換えユニット106は、電動モータ103の出力軸109と同軸に連結された第1伝達軸(入力軸)110と、第1伝達軸110と同軸にかつ、回転可能に設けられた第1ロータ(第1回転体)112と、第1伝達軸110に同軸にかつ、回転可能に設けられた第2ロータ111と、第1ロータ112と第2ロータ(第2回転体)111との間で第1伝達軸110の連結先を切り換える(第1伝達軸110の回転トルクを、第1ロータ112と第2ロータ111とに選択的に伝達する)ためのクラッチ機構113とを備えている。第2ロータ111は、第1伝達軸110に対し、電動モータ103と反対側に配置されている。
第1伝達軸110は、転がり軸受150および円環状の第1フィールド151(後述する)を介して電動モータ103の出力軸109と同軸に回転可能に支持されている。具体的には、ケーシング107に第1フィールド151が内嵌固定されるとともに(図8および図9では、ケーシング107は図示せず)、その第1フィールド151に転がり軸受150の外輪が内嵌固定されている。
アーマチュア支持用ハブ154は、たとえば円環状の板ばねによって形成されている。アーマチュア支持用ハブ154は、第2アーマチュアハブ156と対向する第1対向面157を有している。第1対向面157には、第2アーマチュアハブ156と係合するための第2アーマチュア158が固定配置されている。
また、円環板状の板ばね部165に対し、第2ロータ111の反対側(図8および図9で示す左側)に、第1伝達軸110の主軸部114および第1ロータ本体部164を取り囲む円環板状の係合板(固定部材)171が設けられている。係合板171は、ケーシング107に外付け固定されている。この係合板171として、たとえば切換えユニット106のケーシング107から抜止め用の板を用いることができる。係合板171は、板ばね部165の他方面168に対向する対向面172を有している。対向面172には、係合片170とロック係合するための係合溝169が形成されている。係合板171には、周方向の複数位置(たとえば3位置)に係合溝169が形成されている。前述のように、第1ロータ112の回転に伴ってシフトセレクトシャフト101が軸方向に往復移動するので、第1ロータ112の回転姿勢と、シフトセレクトシャフト101の軸方向位置とは連動している。係合溝169の形成位置は、シフトセレクトシャフト101が所定のセレクト位置(3位置)にあるときの第1ロータ112の係合片170と係合する位置に設定されている。そのため、いずれかの係合溝169が係合片170とロック係合する。これにより、第1ロータ112がケーシング107に連結する。このケーシング107との連結状態では、第1ロータ112はケーシング107によって保持されており、回転不能である。
一方、第1電磁コイル119の励磁状態(図9参照)では、第1アーマチュア167が第1電磁コイル119を含む第1フィールド151に吸引されて、第1アーマチュア167が第2ロータ111側(図8および図9に示す右側)に向けて移動し、第1アーマチュア167が第1アーマチュアハブ153と摩擦係合する。このとき、板ばね部165が、その周縁部が第1フィールド151側に近づくように弾性変形する。板ばね部165の弾性変形に伴って、係合片170が係合溝169から離反する方向(図8および図9に示す右方)に向けて移動し、これにより、係合片170と係合溝169とのロック係合が外れる。
第1伝達軸110と第2ロータ111との連結時(図8参照)には、第2クラッチ116が連結状態にあり、第1クラッチ117が解放状態にある。このとき、第2電磁コイル118は励磁状態にあり、第1電磁コイル119は無励磁状態にある。この状態では、第2アーマチュア158が第2フィールド159に吸引されて、第2アーマチュア158が第2アーマチュアハブ156と摩擦係合する。これにより、第2アーマチュア158と第1伝達軸110との係合が達成されて、第2ロータ111は第1伝達軸110に連結する。また、第1電磁コイル119が無励磁状態であるので、係合片170と係合溝169とがロック係合し、第1ロータ112がケーシング107に連結し、回転不能である。
また、係合片170が第1アーマチュア167と一体移動可能に設けられている。そのため、ケーシング107との連結のための部材を別途設ける必要がないので、さらにコストダウンを図ることができる。
以上、この発明の2つの実施形態について説明したが、この発明は他の形態でも実施することができる。
また、第2実施形態において、係合板171の形状は、円環板状に限られない。また、それぞれ係合溝169が形成された複数の板材を組み合わせて構成されていてもよい。
また、第2実施形態において、第1ロータ112とケーシング107との連結状態を、第1実施形態のような摩擦係合により実現するものであってもよい。
また、第2実施形態において、シフトセレクトシャフト101を軸方向に移動させる(セレクト動作させる)ための第1ロータ112と、ケーシング107とを連結させる構成を例に挙げて説明したが、これに代えて、シフトセレクトシャフト101を回転させる(シフト動作させる)ための第2ロータ111と、ケーシング107とを連結させる構成が採用されていてもよい。また、第1ロータ112およびケーシング107を連結させる構成、ならびに第2ロータ111およびケーシング107を連結させる構成の双方が採用されていてもよい。
