Description
請求項2記載の発明は、回転電機、内燃機関、および駆動輪間の動力分割のための回転体であって且つ互いに連動して回転する複数の動力分割用回転体を備える車載動力伝達装置において、前記動力分割用回転体のうちの第1の回転体と前記内燃機関との間の動力の伝達および遮断を行なう動力伝達制御手段を備え、前記動力伝達制御手段によって前記第1の回転体の正の出力回転エネルギが前記内燃機関に伝達される場合、前記動力分割用回転体のうち前記第1の回転体以外の複数の回転体の出力回転エネルギの符号に互いに相違するものがあり、前記動力分割用回転体は、互いの回転速度が共線図において1直線上に並ぶ4つの回転体を備え、前記駆動輪には、前記4つの回転体のうちの前記共線図上の中間の回転速度に対応する回転体であって且つ前記第1の回転体と相違する回転体が機械的に連結されてなることを特徴とする。
さらに、上記発明では、中間の回転速度に対応する回転体に駆動輪が機械的に連結されるため、駆動輪の正回転、停止、逆回転が容易となる。また、駆動輪に機械的に連結される回転体と第1の回転体とを別とすることで、内燃機関を始動するに際し、第1の回転体の回転速度を駆動輪の回転速度とは別に設定することができる。
加えて、請求項1記載の発明では、変速装置の変速比を操作することで、共線図の傾きを制御することができる。このため、駆動輪が様々な速度をとる場合であっても、変速比の操作によって第1の回転体の回転速度を制御することができる。このため、動力伝達制御手段によって第1の回転体のトルクが内燃機関に伝達される際の第1の回転体の回転速度を好適に制御することができる。
さらに、上記発明では、中間の回転速度に対応する回転体に駆動輪が機械的に連結されるため、駆動輪の正回転、停止、逆回転が容易となる。また、駆動輪に機械的に連結される回転体と第1の回転体とを別とすることで、内燃機関を始動するに際し、第1の回転体の回転速度を駆動輪の回転速度とは別に設定することができる。
以下、本発明にかかる車載動力伝達装置及び車両用駆動装置の第1の実施形態について、図面を参照しつつ説明する。
Ts=−ρTc/(1+ρ) …(c2)
β(Tm+Tr)=Ts …(c3)
上記の式(c1)及び式(c2)を用いて上記式(c3)からトルクTr,Tsを消去することで、下記の式(c4)を得る。
上記の式(c4)によれば、比ρと比βとを近似させることで、第2遊星歯車機構24のキャリアC(動力分割装置20の出力軸)のトルクTcは、非常に大きなものとなり得ることがわかる。換言すれば、駆動輪14に伝達されるトルクが非常に大きなものとなり得ることがわかる。このため、モータジェネレータ10を大型化することなく、発進時のトルクを確保することができる。
以下、第2の実施形態について、先の第1の実施形態との相違点を中心に図面を参照しつつ説明する。
以下、第3の実施形態について、先の第1の実施形態との相違点を中心に図面を参照しつつ説明する。
以下、第4の実施形態について、先の第1の実施形態との相違点を中心に図面を参照しつつ説明する。
以下、第5の実施形態について、先の第1の実施形態との相違点を中心に図面を参照しつつ説明する。
以下、第6の実施形態について、先の第1の実施形態との相違点を中心に図面を参照しつつ説明する。
以下、第7の実施形態について、先の第1の実施形態との相違点を中心に図面を参照しつつ説明する。
なお、上記各実施形態は、以下のように変更して実施してもよい。
