Description

【０００１】
【技術分野】
本発明は、自動車に搭載されるエンジンもしくはそのユニットのロール方向の動きや振動を抑制するためのトルク支持用の連結ロッドに関するものである。
【０００２】
【背景技術】
乗用車等の自動車に搭載されるエンジンは、通常、トランスミッション等を含めたユニットに構成されて車体に組み込まれ、防振マウントにより支持される。この際、前記エンジンユニットのロール方向の動き又は振動を抑制するために、該ユニットの一部（主に下部）が車輌走行方向とは反対方向に延びるトルクロッドと称する連結ロッドにより車体に連結されている。
【０００３】
前記の連結ロッドは、図１４に例示するように、例えば金属製のパイプ材よりなるロッド本体１０１と、該ロッド本体１０１の両端に連設された二つの筒体１０２，１０３と、両筒体１０２，１０３内に装設された防振ブッシュ１０４，１０５とからなる。防振ブッシュ１０４，１０５は、内筒１４１，１５１と外筒１４２，１５２との間にゴム状弾性体１４３，１５３を介在させてなり、外筒１４２，１５２を前記筒体１０２，１０３に圧入することにより固着されている。
【０００４】
かかる連結ロッドにおいて、防振特性を改善する目的で、前記ロッド本体１０１にダイナミックダンパー２００が設けられており、このダンパー２００を構成する質量調整用の質量部材１０６がロッド本体１０１の一部に取着されている。
【０００５】
従来、前記質量部材１０６は、図１４のように、例えばロッド本体１０１に対して、該質量部材１０６と固定板１０６ａとにより該ロッド本体１０１を挟んでリベット止めすることにより取り付けられている。１０６ｂはリベット止め部分を示す。
【０００６】
しかし、取付位置を調整しながらのリベット止めによる取付けは、その作業に手数がかかり、固有振動数のチューニングも容易ではない。しかも、質量部材１０６がロッド本体１０１より外方へ大きく張り出した状態になるため、これがエンジンユニットを車体に連結して支持する場合に邪魔になることがあり、またエンジンルームに余分なスペースを確保する必要もある。
【０００７】
本発明は、上記のトルク支持用の連結ロッドとして、ダイナミックダンパーとしての機能を持たせるための質量調整用の質量部材を、ロッド本体に対して外方へ張り出さないように取付でき、さらには固有振動数のチューニングも容易で、組立性および搭載性に優れたものを提供する。
【０００８】
【発明の開示】
本発明の請求項１に係る連結ロッドの製造方法は、ロッド本体と、その両端に連設されたブッシュ保持用の筒体と、両筒体の内部に装備された内筒付の防振ブッシュと、前記ロッド本体に付設された質量部材を含むダイナミックダンパーとからなり、前記ロッド本体が断面略Ｕ字形をなしており、前記質量部材が、前記ロッド本体の内側に配置されて、ゴム状弾性体を介して前記ロッド本体の一部に取付けられてなる連結ロッドの製造方法であって、断面略Ｕ字形をなすロッド本体の中央板部に長手方向の長方形をなす取付用孔を開設し、前記質量部材にゴム状弾性体を介して取付板部材を連設するとともに、該取付板部材に前記取付用孔の相対向する孔縁部に対応させて一対の係合片を起立状に設け、前記ロッド本体の内側から前記一対の係合片を前記取付用孔に嵌入させて、前記取付板部材が前記中央板部の内面に対接せしめられた状態にて前記一対の係合片をそれぞれ外側に折り曲げて、前記取付用孔の相対向する孔縁部に対して前記係合片をかしめ固定することにより、前記取付板部材を前記ロッド本体に取付けることを特徴とする。
【０００９】
これにより、ロッド本体をダイナミックダンパーとして機能させるための前記質量部材は、断面略Ｕ字形をなすロッド本体の内側に配置されて、ロッド本体から外方へ大きく張り出すことがない。そのため、エンジンユニットを支持するトルクロッドとして使用する場合において、スペース的に前記質量部材が邪魔になることがなく、またエンジンルームに余分なスペースを確保する必要もない。
【００１０】
また、前記のかしめ固定による取付構造によれば、前記質量部材を、ロッド本体に対して所定の位置に正確に取付けることができる。また、リベット止め等の作業を必要としないため、質量の調整や固有振動数のチューニングも容易になる。
【００１１】
なお、前記のように質量部材を取付けることにより、連結ロッドによる支持対象物の振動に対して質量部材が前記ゴム状弾性体のばね作用により共振して、ダイナミックダンパーとしての振動吸収作用を良好に果たす。
【００１２】
また、この場合、前記質量部材に取付板部材をゴム状弾性体の加硫成形により連設しておきさえすれば、前記取付板部材の係合片をロッド本体の取付用孔に対し嵌入してかしめ固定するだけで所定位置に取付けでき、取付け操作を容易に行える。
【００１３】
特に、前記ロッド本体の中央板部に長手方向の長方形をなす取付用孔を開設し、該取付用孔の相対向する孔縁部に対して係合片をかしめ固定するので、係合片のかしめ作業を、前記取付用孔から質量部材を確認しながら容易に行える。
【００１４】
本発明の請求項２に係る連結ロッドは、ロッド本体と、その両端に連設されたブッシュ保持用の筒体と、両筒体の内部に装備された内筒付の防振ブッシュと、前記ロッド本体に付設された質量部材とからなり、前記ロッド本体が断面略Ｕ字形をなしており、前記質量部材は、前記ロッド本体の内側に配置されて、ゴム状弾性体を介して前記ロッド本体の一部に取付けられてなる連結ロッドであって、断面略Ｕ字形をなすロッド本体の中央板部にロッド本体の長手方向に間隔をおいて二つの取付用孔が設けられ、長方形の板材を略Ｕ字形に折曲形成してなる取付板部材を備え、前記質量部材が、前記取付板部材の内側に配されて前記ゴム状弾性体を介して連設されており、前記取付板部材の略Ｕ字形の両側板部の上端部分が、前記質量部材の上面位置よりも上方の位置でそれぞれ外方に折曲されて対接用の段面を形成してから、上方に折曲されることで前記取付用孔に対する係合片として延設され、前記二つの取付用孔に対して前記ロッド本体の内側から前記係合片が挿入されてかしめ固定されることにより、前記取付板部材は、前記段面が前記中央板部の内面に対接した状態で、前記ロッド本体に取付けられてなることを特徴とする。
【００１５】
この場合も、取付板部材の係合片をロッド本体の取付用孔に対し挿入してかしめ固定するだけで、質量部材をロッド本体内の所定の位置に確実に取付けでき、外観的な体裁も良好になる。
【００１６】
また、この場合、特に質量部材およびゴム状弾性体がロッド本体と取付板部材とにより囲まれることになり、他物との接触等による破損を防止できる。
【００１７】
本発明の請求項３に係る連結ロッドは、請求項２記載のものにおいて、前記質量部材と前記取付板部材とが両者に加硫接着されたゴム状弾性体により連設されてなるものであり、この場合、質量部材と取付板部材との一体性に優れる。
【００１８】
本発明の請求項４に係る連結ロッドは、ロッド本体と、その両端に連設されたブッシュ保持用の筒体と、両筒体の内部に装備された内筒付の防振ブッシュと、前記ロッド本体に付設された質量部材とからなり、前記ロッド本体が断面略Ｕ字形をなしており、前記質量部材は、前記ロッド本体の内側に配置されて、ゴム状弾性体を介して前記ロッド本体の一部に取付けられてなる連結ロッドであって、断面略Ｕ字形をなすロッド本体の中央板部に取付用孔が設けられ、長方形の板材を略Ｕ字形に折曲形成してなる取付板部材を備え、前記質量部材が、前記取付板部材の内側に配されて前記ゴム状弾性体を介して連設されており、前記取付板部材の両端部が前記取付用孔に対する係合片として延設され、前記取付用孔に対して前記両端部の係合片が挿入されてかしめ固定されることにより、前記取付板部材が前記ロッド本体に取付けられ、前記質量部材が、その両側に加硫接着されたゴム状弾性体を介して前記取付板部材の略Ｕ字形の両側板部間に前記ゴム状弾性体の弾性力を利用して嵌着されるとともに、該ゴム状弾性体がロッド本体と取付板部材との間に挟着されて保持されてなることを特徴とする。この場合、ゴム状弾性体を加硫接着した質量部材を、取付板部材とロッド本体の中央板部との間に挟み込むようにして係合片をかしめ固定することにより容易に取着できる。
【００１９】
本発明の請求項５に係る連結ロッドは、ロッド本体と、その両端に連設されたブッシュ保持用の筒体と、両筒体の内部に装備された内筒付の防振ブッシュと、前記ロッド本体に付設された質量部材とからなり、前記ロッド本体が断面略Ｕ字形をなしており、前記質量部材は、前記ロッド本体の内側に配置されて、ゴム状弾性体を介して前記ロッド本体の一部に取付けられてなる連結ロッドであって、断面略Ｕ字形をなすロッド本体の中央板部の略中央部分が略円形に拡張形成されるとともに、該中央部分に円形の取付用孔が設けられ、前記質量部材が、前記円形の中央部分より径小の円形状をなしており、該質量部材にゴム状弾性体を介して連設された円環状の取付板部材の内外縁の一方が前記取付用孔に嵌合されてその孔縁部に対しかしめ固定されることにより、円形の中央部分の内側に配されてなるものである。
【００２０】
この場合も、取付板部材の係合片のロッド本体の取付用孔に対するかしめ固定作業を容易に行え、質量部材をロッド本体の中央部分の内側に確実に配置でき、ダンパーとしての作用も良好に行われる。しかも、質量部材が大きく外方に張り出すことがなく、前記質量部材が使用上の邪魔になることもない。
【００２１】
本発明の請求項６に係る連結ロッドは、ロッド本体と、その両端に連設されたブッシュ保持用の筒体と、両筒体の内部に装備された内筒付の防振ブッシュと、前記ロッド本体に付設された質量部材とからなり、前記ロッド本体が断面略Ｕ字形をなしており、前記質量部材は、前記ロッド本体の内側に配置されて、ゴム状弾性体を介して前記ロッド本体の一部に取付けられてなる連結ロッドであって、前記質量部材は、略Ｕ字形をなす取付板部材の内側にゴム状弾性体を介して連設されてなり、該取付板部材が前記ロッド本体に対し圧入手段により嵌着されることにより、ロッド本体の内側に配置されて取付けられてなり、断面略Ｕ字形をなすロッド本体の中央板部に取付用孔が設けられ、前記質量部材が該取付用孔を通してロッド本体の内側に配置されるように、略Ｕ字形の取付板部材がロッド本体の外側に嵌着されてなることを特徴とする。
この連結ロッドにおいても、ロッド本体に対する取付板部材の圧入により、質量部材を断面略Ｕ字形をなすロッド本体内側の所定の位置に容易に確実に取着でき、質量の調整やチューニングが容易であり、しかも外方へ大きく張り出すこともない。しかも、この場合、圧入時の位置決めが容易であり、圧入操作を容易に行える。
【００２２】
【発明を実施するための最良の形態】
以下に、発明の連結ロッドの好適な実施例を図面を参照しながら説明するが、本発明はこれに限定されるものではない。
【００２３】
図１〜図４は、本発明の連結ロッドの第１実施例を示している。
【００２４】
図において、１は所要長さの金属材よりなるロッド本体を、２，３はロッド本体１の両端にそれぞれ連設されたブッシュ保持用の筒体を、４，５は両筒体２，３の内部にそれぞれ装設した内筒付の防振ブッシュを示し、６は前記ロッド本体１に付設された質量部材を示す。
【００２５】
前記ロッド本体１は、図のように断面略Ｕ字形をなし、その両端が前記両筒体２，３の外周に溶接されて連設されている。断面略Ｕ字形としては、図のような角張った断面略Ｕ字形のものに限らず、中央板部１ａと両側板部１ｂ，１ｂとの間の角部のアールを大きくとったもの、また両側板部１ｂ，１ｂをテーパ状に開口側を拡開させたもの、あるいは両側板部１ｂ，１ｂを湾曲させたもの等、他の断面略Ｕ字形をなすものであってもよい。
【００２６】
前記防振ブッシュ４，５は、いずれも軸部材（図示せず）に対する取付部材となる内筒４１，５１と外筒４２，５２との間にゴム状弾性体４３，５３を介在させてなり、前記筒体２，３に対して外筒４２，５２が圧入されて固着されている。図の場合、径大側の防振ブッシュ５は、ゴム状弾性体５３に軸方向に貫通した空洞５４が設けられている。防振ブッシュは、前記の外筒４２，５２を省略して、筒体２，３内に装設するることもできる。
【００２７】
そして、この第１実施例の場合、前記質量部材６は次の構成により前記ロッド本体１の略中央部の内側に配置されて取付けられている。
【００２８】
前記ロッド本体１の中央板部１ａの略中央部に長方形の取付用孔９が開設されている。この取付用孔９の位置は、ダンパーとしての共振作用等に応じて適宜設定できる。前記質量部材６は直方体形状をなしており、その片側面にゴム状弾性体７を介して取付板部材８が連設されている。ゴム状弾性体７は質量部材６と取付板部材８との双方に加硫接着されている。質量部材６は、円柱形状や角形や円形の環状をなすもの、その他のどのような形態であってもよく、その大きさについても要求される質量等に応じて適宜設定できる。
【００２９】
前記取付板部材８は、図４のように、長方形の板材の中央部に前記ロッド本体１の取付用孔９に対応する開口が設けられ、該開口の一方の相対向する両辺部、例えば図のようにロッド長手方向に相対向する両辺部に係合片８ａ，８ａが起立状に設けられてなる。
【００３０】
質量部材６は、前記係合片８ａ，８ａがロッド本体１の内側から前記取付用孔９に嵌め込まれて、該取付板部材８が前記中央板部１ａの内面に対接せしめられた状態において、前記係合片８ａ，８ａがかしめ固定手段により外側に折り曲げられて孔縁部に対し固定されることにより、ロッド本体１の内側にゴム状弾性体７を介して支持されている。これにより支持対象物の振動に対して前記質量部材６がロッド本体１内で共振でき、ダイナミックダンパーとしての振動吸収作用を果たす。
【００３１】
この実施例の連結ロッドによれば、ロッド本体１をダイナミックダンパーとして機能させるための質量部材６を、取付用孔９の縁部に対する取付板部材８のかしめ固定により所定の位置に正確に付設できるので、質量の調整及び固有振動数のチューニングや設定が容易になる。しかも、前記質量部材６が、断面略Ｕ字形のロッド本体１内にあって、ロッド本体１から大きく張り出すことがない。
【００３２】
図５〜図７は、本発明の連結ロッドの第２実施例を示している。この第２実施例において、第１実施例と共通する構成部材及び構成部位については同符合を付している。
【００３３】
この第２実施例においては、断面略Ｕ字形をなすロッド本体１の中央板部１ａにロッド本体の長手方向に間隔をおいて二つの取付用孔９２，９２が設けられ、この二つの取付用孔９２，９２に対して、質量部材６にゴム状弾性体７２を介して連設されている取付板部材８２の両側に存する係合片８２ａ，８２ａが挿入されてかしめ固定されている。
【００３４】
この実施例において、前記取付板部材８２は長方形の板材を略Ｕ字形に折曲形成したものよりなり、この取付板部材８２の内側に前記質量部材６が配されて、該取付板部材８２との間に介在するゴム状弾性体７２により連設されている。ゴム状弾性体７２は質量部材６と取付板部材８２の中央部との両者に加硫接着されている。前記ゴム状弾性体７２を、質量部材６の両側面と取付板部材８２の両側板部８２ｃ，８２ｃとの間に介在させることもできる。
【００３５】
前記取付板部材８２の両端部、すなわち略Ｕ字形の両側板部８２ｃ，８２ｃの上端部分が、前記質量部材６の上面位置よりやや上方の位置で外方へ折曲されて対接用の段面８２ｂ，８２ｂが形成され、さらにその先端部が上方へ折曲されて係合片８２ａ，８２ａとして延成されている。
【００３６】
そして、前記係合片８２ａ，８２ａがロッド本体１の内側から前記取付用孔９２、９２に挿入されて、前記段面８２ｂ，８２ｂが前記中央板部１ａの内面に対接せしめられ、この状態で前記係合片８２ａ，８２ａが取付用孔９２，９２の縁部に係合させるようにかしめ固定されることにより、前記質量部材６がロッド本体１の内側に配置されて支持されている。
【００３７】
この実施例の場合も、前記質量部材６をロッド本体１から外方へ突出させることなく嵩低く容易に装備でき、質量の調整及び固有振動数のチューニングや設定も容易である。また質量部材６は、支持対象物の振動に対してロッド本体１内で共振でき、ダイナミックダンパーとしての振動吸収作用を良好に果たすことができる。
【００３８】
上記の第２の実施例において、前記取付板部材８２は、上記の第１実施例の場合と同様に質量部材６の片側面にゴム状弾性体を介して連設され、前記取付用孔９２，９２に挿入できる二つの係合片が相対向して設けられてなるものであってもよいが、質量部材やゴム状弾性体の保護の点からは、上記の取付板部材８２のように、質量部材６およびゴム状弾性体７２を囲む形態のほうが好ましい。
【００３９】
図８および図９は、上記の第２実施例の変更例を示しており、上記の第２実施例と共通する構成部材及び構成部位については同符合を付している。
【００４０】
この実施例においては、前記質量部材６の両側に略Ｔ字形をなすゴム状弾性体７２ａ，７２ａが加硫接着されている。この質量部材６は、前記ゴム状弾性体７２ａ，７２ａを介して、上記第２実施例と同様の略Ｕ字形をなす取付板部材８２の両側板部８２ｃ，８２ｃ間にゴム状弾性体の弾性力を利用して嵌着されている。さらに前記の嵌着状態で、前記係合片８２ａ，８２ａが、ロッド本体１の内側から前記取付用孔９２、９２に対し挿入されて、図８のように取付用孔９２，９２の縁部にかしめ固定されることにより、前記ゴム状弾性体７２ａ，７２ａの端部がロッド本体１と取付板部材８２との間に挟着されて保持されている。このため、前記ゴム状弾性体７２ａ，７２ａの端部の上下方向の寸法は、取付板部材８２の中央部から段面８２ｂまでの寸法よりやや大きく形成される。
【００４１】
この実施例の場合も、前記のようにダイナミックダンパーとして機能を持たせるための質量部材６を、ロッド本体１内の所定位置に外方へ突出させることなく嵩低く容易に装備できる。
【００４２】
図１０および図１１は、本発明の連結ロッドの第３実施例を示しており、上記の実施例と共通する構成部材及び構成部位については同符合を付している。
【００４３】
この実施例においては、断面略Ｕ字形をなすロッド本体１の中央板部１ａの長手方向の略中央部分が略円形に拡張形成されるとともに、該中央部分に円形の取付用孔９３が形成されている。一方、質量部材６は、前記中央板部１ａの中央部分より径小の円形状をなし、該質量部材６の片側面にゴム状弾性体７３を介して円環状の取付板部材９３が連設されている。ゴム状弾性体７３は質量部材６と取付板部材９３の両者に加硫接着されている。
【００４４】
前記取付板部材８３の内外縁の一方、例えば図のように内縁部８３ａが、前記取付用孔９３に対する係合部として筒状に折曲延成されており、前記ロッド本体１の内側において、前記内縁部８３ａが前記ロッド本体１の取付用孔９３に嵌合されて孔縁部に対しかしめ固定されることにより、前記質量部材６がロッド本体１の前記中央部分の内側に配置されゴム状弾性体７３を介して支持されている。
【００４５】
この場合、前記質量部材６の質量を大きく設定することが可能で、ダンパーとしての作用も良好に行われる上、取付板部材８３のロッド本体１の取付用孔９３に対するかしめ固定作業も容易に行える。なお、質量部材６の形状は、図示するような円環状や円板状をなすものには限らず、他の形状での実施も可能である。
【００４６】
図１２〜図１３は、本発明の連結ロッドの第４実施例を示しており、上記の実施例と共通する構成部材及び構成部位については同符合を付している。
【００４７】
この実施例において、質量部材６は、断面略Ｕ字形のロッド本体１に対して嵌着可能な略Ｕ字形をなす取付板部材８４の内側に配置されてゴム状弾性体７４を介して取付板部材８４の中央部に連設されている。すなわち、前記質量部材６と取付板部材８４の中央部とが両者に加硫接着されたゴム状弾性体７４により連設されて、質量部材６と取付板部材８４の両側板部との間に間隔を保有している。前記質量部材６は、前記取付板部材８４が前記ロッド本体１に対し圧入手段により外側に嵌着されることにより、ロッド本体１内の所定の位置に配置されて取付けられている。
【００４８】
特に、図１２および図１３の場合、前記ロッド本体１の中央板部１ａに質量部材６が通る取付用孔９４を設け、前記質量部材６を該取付用孔９４を通すようにして、前記の取付板部材８４をロッド本体１に対して断面略Ｕ字形の開口とは反対側から圧入して嵌着している。この場合、圧入時の位置決めが容易で圧入操作を容易に行える。
【００４９】
これらの実施例の連結ロッドにおいても、質量部材６を断面略Ｕ字形をなすロッド本体１内の所定の位置に容易に確実に取着できる。
【００５０】
上記した各実施例の連結ロッドは、主としてトランスミッション等を含むエンジンユニットを車体に組み込んで防振マウントにより支持する場合に、エンジンユニットのロール方向の動き又は振動を抑制するために、該ユニットの一部を車体に連結するトルクロッドとして使用する。
【００５１】
この使用において、前記質量部材６が連結ロッドによる支持対象物の振動に対してゴム状弾性体のばね作用により共振することで、ダイナミックダンパーとして良好な振動吸収作用を果たすことができる。
【００５２】
また、質量を調整するため前記質量部材６は、ロッド本体から大きく、あるいは全く張り出すことがないため、前記質量部材が邪魔にならず、またエンジンルームに余分なスペースを確保する必要もなく、搭載性及び組立て性を向上できる。
【００５３】
【産業上の利用可能性】
本発明の連結ロッドによれば、ダイナミックダンパーとしての機能を持たせるための質量調整用の質量部材を、ロッド本体に対して加硫成形により容易に、かつ外方への張り出しを抑えてコンパクトに付設装備でき、組立性および搭載性に優れ、自動車用エンジンを車体に搭載し支持する場合のトルク支持用のトルクロッドとして特に好適に使用できる。
