The case where the dimension h is enlarged is shown).

Abstract
Description
(1)
構成・・・
(1-1)自動車用等プロペラシャフトの中間軸受を防振支持するセンターベアリングサポートの弾性体に形成されたスグリにおいて、略三角形を対向させた形状を持つもの(図2)。同様にスグリ形状を凹凸形状としても良い(図4)。これらのスグリは等配設定が望ましいが、円周各方向のばね定数調整のために不等配としても良い。
(1-2)図2に示すごとく略三角形のスグリを対向させように配置し、弾性体部が薄くなる繋ぎ部の長さを確保する。図4のごとく凹凸形状の組み合わせとしても良い。
効果・・・
(1-3)上記構成により軸方向変形時に負荷の高い繋ぎ部の長さを長く設定することができ、耐久性の向上を見込むことができる。同じ支持剛性(径方向ばね定数)とした場合の径方向および軸方向の剛性比(径・軸剛性比)は図5に示すようになる。
(1-4)略三角形状において円周方向のクリアランスが確保できるため、予圧縮を与えた際にも低支持ばねを長いストロークで確保できる。図6に径方向の変位に対する反力を示す。
構成・・・
(2-1)自動車用等プロペラシャフトの中間軸受を防振支持するセンターベアリングサポートの弾性体において、車両下方向に略逆U字形などの抜きを設けることで、車両下方向のバネ成分を圧縮+せん断としたもの。
(2-2)相手部品となるシャシ側を上記抜きに沿わせる形状としても良い。
(2-3)車両下方向、シャシとの間に略逆U字形などの抜きを設けることで、車両下方向のバネ成分を圧縮+せん断とする。
効果・・・
(2-4)上記構成により高い支持剛性を維持しつつ、プロペラシャフトの挙動(ストローク)し得るスペースが確保できる。
(2-5)スグリおよび抜き部の形状により圧縮+せん断バネ成分の比率を変えることにより、弾性体における弾性率(例えばゴム硬さ)による調整のみでなく、形状による特性チューニングの幅が広がり、設計自由度を高めることが可能となる。また、抜き部の深さ(高さ)により、支持剛性を変えずにストローク量の調整も可能となる。
(2-6)シャシ側を抜きに沿う形状にすることで、従来の圧縮バネによる特性も再現可能となり、例えば車両特性によるセンターベアリングサポートへの支持剛性違いの要求に対しても、1つの仕様にて追随することが可能となり、製品仕様の統合が可能となる。
図1ないし図3は、本発明の第1実施例に係るセンターベアリングサポート11を示している。当該実施例に係るセンターベアリングサポート11は、自動車等車両においてセンターベアリング(中間軸受、図示せず)を介してプロペラシャフト(推進軸、図示せず)を弾性的に防振支持するものであって、以下のように構成されている。
上記第1実施例において、繋ぎ部23は軸方向一方からこれを見て、所定の幅寸法を備える直線状に形成されているが、これに替えて、繋ぎ部23は軸方向一方からこれを見て、所定の幅寸法を備える曲線状に形成されたものであっても良い。
上記第1および第2実施例において、装着時シャシに対向するゴム状弾性体12の下面部16は平面状に形成されているが、このように下面部16が平面状であると下面部16はシャシに対し全面接触するため、プロペラシャフトの荷重や振動などが作用したとき、ゴム状弾性体12は軸孔13および軸挿通部14の直下位置(図2または図4において図面上に点々を付した部位)において、そのばね成分が圧縮ばねのみとされる。しかしながら上記したように圧縮ばねはその反力が2次曲線的に大きく立ち上がってしまうため(図8における比較例の線)、プロペラシャフトの挙動が部分的に制限され、実車における振動の発生が問題となるケースがある。
