Description
図1を参照して、エンジンマウント1は、自動車等の車両において、内燃機関であるエンジン2(第1部材の一例)と車体3(第2部材の一例)の間に配置されている。エンジンマウント1は、エンジン2の振動を抑制しつつ、エンジン2を支持するための部品である。
エンジン2が振動すると、第1取付部材5と第2取付部材6が相対変位するのに応じて、第1壁体7と第2壁体8が弾性変形し、第1液室10と第2液室11の容積が変化する。例えば、第1取付部材5が第2取付部材6に対して下降すると、第1壁体7及び第2壁体8が下方に弾性変形し、第1液室10の容積が減少すると共に第2液室11の容積が増加する。一方で、第2取付部材6が第1取付部材5に対して上昇すると、第1壁体7及び第2壁体8が上方に弾性変形し、第1液室10の容積が増加すると共に第2液室11の容積が減少する。
マウント液Mは、非ニュートン流体のみによって構成されている。なお、他の異なる実施形態では、マウント液Mは、非ニュートン流体とニュートン流体の両方によって構成されていても良い。
図3は、オリフィス通路12を示している。但し、図3では、実際には円弧状に湾曲しているオリフィス通路12が、模式的に直管状に表示されている。また、図3では、オリフィス通路12内を分かりやすく表示するために、オリフィス通路12の紙面奥側の半分のみが表示されている。図3の2点鎖線Xは、オリフィス通路12の軸心を示している。図3の点線矢印Aは、第1液室10から第2液室11に向かうマウント液Mの流れを示し、図3の点線矢印Bは、第2液室11から第1液室10に向かうマウント液Mの流れを示している。
マウント液Mが第1液室10から第2液室11に流入する場合、マウント液Mがオリフィス通路12を第1連通口31から第2連通口32に向かって流れる。この時、オリフィス通路12が第1連通口31から第2連通口32に向かって徐々に拡径しているため、マウント液Mを構成するチキソ流体のせん断速度は徐々に低下し、チキソ流体の粘度は徐々に上昇する。
上記のように、本実施形態では、第1連通口31の開口面積が第2連通口32の開口面積とは異なっている。そのため、マウント液Mの流れ方向によってマウント液Mのせん断速度が変化し、マウント液Mを構成するチキソ流体のせん断速度及び粘度も変化する。これにより、逆止弁を有するオリフィス通路を複数設けることなく、エンジンマウント1の振動減衰特性をマウント液Mの流れ方向によって変化させることができる。つまり、エンジンマウント1の大型化、製造コストの上昇、耐久性の問題を生じさせずに、マウント液Mの流れ方向によってエンジンマウント1の振動減衰特性に異方性を持たせることができる。
以下、本発明の好適な変形例について説明する。但し、上記実施形態と同様の事項については、説明を省略する。
図4は、本発明の第1変形例に係るオリフィス通路41を示している。
図5は、本発明の第2変形例に係るオリフィス通路51を示している。
図6は、本発明の第3変形例に係るオリフィス通路61を示している。
上記実施形態では、オリフィス通路12がその軸心方向において円弧状に湾曲している。一方で、他の異なる実施形態では、オリフィス通路12がその軸心方向において直線状に延びていても良い。
