Claims (2)
- 磁気粘性流体を満たしたシリンダ(21)の内部をピストン(22)で第1流体室(25)および第2流体室(26)に区画し、ピストン(22)を貫通するように形成した流体通路(22a)で前記第1流体室(25)および第2流体室(26)を相互に連通させ、制御手段(U)によりピストン(22)に設けたコイル(28)に通電して流体通路(22a)中の磁気粘性流体の粘性を変化させて減衰力を制御する、車両のサスペンション装置用可変減衰力ダンパーにおいて、
前記ピストン(22)に設けられると共に前記コイル(28)に対しピストン(22)の軸線に沿って並ぶように縦列配置されて前記制御手段(U)により通電制御可能なサブコイル(28′)を備え、
前記制御手段(U)は、前記コイル(28)の断線が検出されないときは車両の運動状態に応じた前記コイル(28)への通電制御を行い、また前記コイル(28)の断線が検出されたときは前記サブコイル(28′)に所定の定電流を供給することを特徴とする、車両のサスペンション装置用可変減衰力ダンパー。 - 前記コイル(28)及びサブコイル(28′)は、前記流体通路(22a)よりもピストン(22)の径方向内側に且つ該流体通路(22a)に隣接して配置されることを特徴とする、請求項1に記載の車両のサスペンション装置用可変減衰力ダンパー。
