Abstract
【解決手段】防振装置10は、筒状の外側取付け部材11および内側取付け部材12と、外側取付け部材11と内側取付け部材12とを連結するとともに、外側取付け部材11の中心軸線Oに沿う軸方向に間隔をあけて配置された一対の本体ゴム13と、外側取付け部材11と内側取付け部材12とを連結するとともに、一対の本体ゴム13間の液室25を、軸方向に第1液室26と第2液室27とに仕切る仕切り部15と、を備え、仕切り部15は、第1液室26と第2液室27とを連通する制限通路33が形成された環状の剛体部30と、剛体部30に対して径方向に連なる環状の弾性部29と、を備え、弾性部29は、剛体部30に対して非接着状態で径方向に圧縮変形させられて当接している。
【選択図】図1
Description
この防振装置では、振動の入力時に、液体が、第1液室と第2液室との間を、制限通路を通して往来することで、入力された振動が減衰、吸収される。
なお、大きな振幅の振動が入力された場合には、弾性部と剛体部とを離間させ、この隙間を通して第1液室と第2液室とを直接連通させることも可能になり、前述の高ばね化をより一層確実に抑えることができる。
この場合、剛体部に突出部が形成されているので、弾性部の前記径方向の大きさを抑えつつ、弾性部の前記径方向の圧縮変形量を確保することが可能になり、弾性部の前記軸方向の曲げ剛性が高められ、防振性能を安定して発揮させることができる。
この場合、突出部の頂面に対する弾性部の接触面積が、頂面の面積より小さくなっているので、突出部の前記軸方向の剛性が確保されるとともに、液室内の液圧が上昇して弾性部が変形若しくは変位したときに、弾性部が剛体部から外れてしまうのを防ぐことができる。
この場合、制限通路の形成された剛体部が、弾性部より前記径方向の外側に配置されているので、制限通路の流路長を容易に確保することが可能になり、チューニングの容易な防振装置を得ることができる。
この場合、弾性部が本体ゴムと一体に形成されているので、この防振装置を容易に形成することができる。
図1に示すように、防振装置10は、内部に液体(例えばエチレングリコール、水、シリコーンオイル等)が封入された、いわゆる液体封入型である。防振装置10は、例えばキャビンマウント等に適用される。
以下では、前記軸方向から見た平面視において、前記中心軸線Oに直交する方向を径方向といい、前記中心軸線O回りに周回する方向を周方向という。
内側取付け部材12は、筒状に形成され、前記中心軸線Oと同軸に配設されている。内側取付け部材12における前記軸方向の両端部は、外側取付け部材11から前記軸方向の外側に突出している。内側取付け部材12における前記軸方向の両端部には、径方向の外側に向けて突出するフランジ部12aが、全周にわたって延設されている。
剛体部30は、全周にわたって連続して延在している。剛体部30は、外側取付け部材11の本体筒11a内において、上リング体11bと下リング体11cとの間に位置する部分に嵌合されている。剛体部30における前記軸方向の両端開口縁は、上リング体11bの下端縁および下リング体11cの上端縁に各別に液密に当接している。制限通路33は、剛体部30の外周面に形成されている。
突出部31の内周面32における前記軸方向の両端部には、全周にわたって連続して延びる若しくは間欠的に延びる突条部32aが各別に形成されている。これらの突条部32aにより、突出部31の内周面32および弾性部29の外周面の相対的な前記軸方向の位置ずれを防いでいる。
また、大きな振幅の振動が入力された場合には、弾性部29と剛体部30とを離間させ、この隙間を通して第1液室26と第2液室27とを直接連通させることも可能になり、前述の高ばね化をより一層確実に抑えることができる。なお、大きな振幅の振動が入力された場合にも、弾性部29と剛体部30とを離間させないようにしてもよい。
また、突出部31の内周面32に対する弾性部29の接触面積が、突出部31の内周面32の面積より小さくなっているので、突出部31の前記軸方向の剛性が確保されるとともに、液室25内の液圧が上昇して弾性部29が変形若しくは変位したときに、弾性部29が剛体部30から外れてしまうのを防ぐことができる。
また、弾性部29が本体ゴム13と一体に形成されているので、この防振装置10を容易に形成することができる。
また、前記実施形態に代えて例えば、弾性部が外側取付け部材の内周面に加硫接着され、この弾性部内に剛体部が嵌合された構成を採用してもよい。
また、剛体部30に突出部31を形成しなくてもよい。
また、前記実施形態に代えて例えば、突出部31の内周面32に対する弾性部29の接触面積を、突出部31の内周面32の面積以上としてもよい。
また、弾性部29として、本体ゴム13に対して分離された構成を採用してもよい。
また、突出部31の内周面32に突条部32aを形成しなくてもよい。
防振装置10は、車両のキャビンマウントに限定されるものではなく、例えば、車両用のエンジンマウントおよびブッシュ、建設機械に搭載された発電機のマウント、並びに、工場等に設置される機械のマウント等に適用してもよい。
