Description
図1は、実施形態のダイナミックダンパが設けられた車両を模式的に示すスケルトン図である。図1に示すように、車両Veは、動力源として、エンジン1と、第1モータ2と、第2モータ3とを備えたハイブリッド車両である。各モータ2,3は、モータ機能と発電機能とを有するモータ・ジェネレータであり、インバータを介してバッテリに電気的に接続されている。車両Veでは、動力源から出力された動力が動力伝達装置4を介して車輪5に伝達される。
ダイナミックダンパ20は、図2に示すように、中空状のカウンタシャフト92の内部に配置されている。このダイナミックダンパ20は、図3に示すように、質量体21と、ゴム22と、ホルダ23とを備えている。
カウンタドリブンギヤ91の共振モードについて説明する。カウンタドリブンギヤ91では、はすば歯車の噛み合いにより生じるスラスト力を強制力として、倒れ込み共振と、軸方向共振とが発生する。
ダイナミックダンパ20は、倒れ込み共振モードに対応した動吸振器の共振モードとしてのダンパ傾きモードと、軸方向共振モードに対応した動吸振器の共振モードとしてのダンパ前後モードとに振動することが可能である。
動吸振器の共振周波数fは、バネ定数kと質量mとを用いて、下式(1)により表される。
f=(1/2π)√k/m ・・・(1)
G=E/[2(1+ν)] ・・・(2)
ここで、ダイナミックダンパ20をより詳細に説明する。
図13は、ダイナミックダンパによる制振効果を示すグラフ図である。図13には、ダイナミックダンパ20における周波数とイナータンスとの関係が、太い実線で示されている。なお、図13には、比較のため、動吸振器が設けられてない場合の周波数とイナータンスとの関係が、細い実線で示されている。
