Abstract
Description
図1に示す MacPherson Strut type の懸架装置1は、懸架用コイルばね2(これ以降、単にコイルばね2と称す)と、ショックアブソーバからなるストラット3とを備えている。コイルばね2は、螺旋形に成形されたばね鋼からなる素線4を有している。コイルばね2は、下側のばね座10と上側のばね座11との間で圧縮された状態で、懸架装置1に取付けられている。ストラット3の上端は、マウントインシュレータ12を介して車体13に取付けられている。ストラット3の下部にブラケット15が設けられている。ブラケット15には、車軸を支持するためのナックル部材16(一部のみ示す)が取付けられている。ストラット3は、重力の鉛直線XLに対し、上端側が車両内側に角度θ1だけ軸線X0が傾いた状態で車体13に取付けられている。
Claims (3)
- 螺旋形に成形された素線(4)を有し、下側のばね座(10)と上側のばね座(11)との間に配置されるコイルばねであって、
前記下側のばね座(10)に接する下側の座巻部(20)と、
前記上側のばね座(11)に接する上側の座巻部(21)と、
前記下側の座巻部(20)と前記上側の座巻部(21)との間の有効部(22)と、
前記有効部(22)を圧縮する力が前記下側の座巻部(20)と前記上側の座巻部(21)とに負荷された状態において、前記下側の座巻部(20)に加わる力の重心(C1)と前記上側の座巻部(21)に加わる力の重心(C2)とを結ぶ直線からなる荷重軸(FL)とを有し、
前記有効部(22)は、圧縮されていない自由形状において該有効部(22)の軸まわりに円筒形であり、指定高さまで圧縮された圧縮形状では、前記荷重軸(FL)をZ軸とする座標系に関し、前記Z軸方向にピッチが一定の円筒形をなしているコイルばね。 - 請求項1に記載のコイルばねにおいて、
前記荷重軸(FL)と前記下側のばね座(10)の中心との差、および前記荷重軸(FL)と前記上側のばね座(11)の中心との差に応じて、前記下側の座巻部(20)と前記上側の座巻部(21)とをコイル中心から偏心させ、かつ、前記指定高さにおける前記下側の座巻部(20)と上側の座巻部(21)の傾きを、それぞれ、前記下側のばね座(10)と上側のばね座(11)の傾きに対応させたコイルばね。 - 請求項1に記載のコイルばねにおいて、
前記圧縮形状の前記有効部(22)のコイル径が、前記自由形状の前記有効部(22)のコイル径と比較して、前記荷重軸(FL)まわりの全周にわたり同等に拡大するコイルばね。
