Abstract
Description
(第1実施形態)
本開示のパワーユニット1は、様々な形態において利用可能である。第1実施形態のパワーユニット1は、一例として車両11に搭載される。図1は、第1実施形態に係る車両11の右側面図である。図2は、図1の車両11の全体的な動力伝達経路を示す模式図である。図3は、図1の車両11の動力系統の部分的な模式図である。
図7は、第2実施形態に係る車両111の動力系統の部分的な模式図である。車両111のパワーユニット101は、単一の走行用の駆動源を備える。この駆動源は、本実施形態ではエンジンEであるが、電動モータMでもよい。エンジンEは、車両11と同様に、クランクケース26と貯留パン27とを有する(図1参照)。またパワーユニット101は、第1ポンプと第2ポンプとを備える。第1ポンプと第2ポンプとしては、所定対象に流体を供給する各種ポンプを選択できる。本実施形態の第1ポンプと第2ポンプとは、互いに異なる回転数で駆動される。また一例として、第1ポンプと第2ポンプとのうち、高回転で駆動される一方のポンプは、他方のポンプよりも高出力又は低脈動が要求されるポンプである。第1ポンプと第2ポンプとは、同一形状であるが、第1ポンプと第2ポンプとの各形状は、これに限定されない。
