Abstract
Description
図16において200はアッパーサポートで、202は筒状をなすインナ金具、204はインナ金具202の径方向外側に配置されたアウタ金具、206はそれらインナ金具202とアウタ金具204とを連結する状態にそれらに一体に加硫接着されたゴム弾性体、208はインナ金具202の上端部に固定されてインナ金具202とともに上下動し、リバウンド時にストッパ作用をなすリバウンドストッパ金具である。
リバウンドストッパ金具208はインナ金具202とは別体で板状に構成されており、インナ金具202に固定されて保持されている。
インナ金具202は、内側の第1金具202-1と、外側の第2金具202-2との2つの金具から成っており、外側の第2金具202-2の上部が、内側の第1金具202-1に対し外嵌状態で溶接され、それら第1金具202-1と第2金具202-2とが接合されている。
そのかしめによる固定は次のようにして行われている。
即ち、図16の部分拡大図に示すようにインナ金具202の上端部外周面を全周に亘り切削加工して、そこに予め円筒状の薄肉部220と、段付部222とを形成しておき、そして薄肉部220に対してリバウンドストッパ金具208を中心穴210において外嵌状態に嵌め合せて、下面を段付部222にて形成される着座面224に着座させ、その着座面224によってリバウンドストッパ金具208を上下方向に位置決状態に支持させる。
例えばかしめ加工されるインナ金具202の上端部が上記のような薄肉部220とされておらず、切削加工前の肉厚のままであると、これを全周に亘り拡径を伴って折り曲げる際に極めて強い力が必要となってかしめ装置が力不足となり、かしめ加工自体が困難化する。
このときに無理に折曲げによるかしめを行うと亀裂や割れ等が発生してしまう。
そこでインナ金具の上端部を薄肉となしておいて、これをかしめ加工するようにしている。上記の薄肉部220の形成はこのような意味を有している。
しかしながら上記の薄肉部220及び段付部222を形成するための切削加工には多大な時間と手間とを要し、その切削加工のためのコストが非常に高いものとなり、このことがアッパーサポート200の製造コストを大きく押し上げる要因となる。
このような狭い幅の着座面224ではリバウンドストッパ金具208をセットする際に、安定してこれを支持することができない場合がある。
而してそのような緩みが生じると、リバウンドストッパ金具208がインナ金具202に対して相対回転をしてしまったり、或いはその緩みに起因してリバウンドストッパ金具208ががたつきを生じ、その際に不快な異音を発生するといった問題が生ずる。
しかしながらこの場合、回転方向の固定力、保持力には自ずと限界があり、インナ金具202とリバウンドストッパ金具208とを回転方向に十分強固に固定することは難しい。
具体的に例示をすれば、例えば、インナ金具を板材の絞り加工にて形成し、その際に底部を打抜き加工するとき、凸係合片を径方向の内向きに残すようにし、その後これを上向きに立ち上げることで、切削加工によらずに簡単にかしめ部となる凸係合片を形成することができる。
尚、板状をなすリバウンドストッパ金具の切欠凹部もまた、例えばプレス加工での打抜き等によって容易に形成することができる。
従って、かしめ加工に際してリバウンドストッパ金具をその着座面で支持させる状態にセットしたときに、リバウンドストッパ金具の座りが良く、これを安定して支持することができ、かしめ加工が行い易くなるとともに、リバウンドストッパ金具を良好にインナ金具に固定することができる。
この場合において、インナ金具の上端部の内径とリバウンドストッパ金具の中心穴の径とを同径とし、インナ金具の上端部の内周面の位置と、リバウンドストッパ金具の中心穴の周面の位置とを合致させておくことができる。
このようにすれば、凸係合片のかしめによる固定強度及び回転方向における固定強度をともにより高強度となすことができる。
本発明では、凸係合片と切欠凹部との機械的ないし物理的な係合によって、インナ金具とリバウンドストッパ金具との間で回転方向の力を確実に伝えて、周方向での当接位置で確実に相対回転阻止できるものの、それらの間に周方向の嵌合クリアランスが生じていると、そこでがたつきを生じることを避け得ず、そしてそのことが不快な異音の発生に繋がる恐れがある。
図1において、10はショックアブソーバのピストンロッドと車体とを弾性連結して、ピストンロッドと車体との間で防振作用するアッパーサポートで、筒状をなすインナ金具12と、インナ金具12の径方向外方に配置されたアウタ金具14と、それらインナ金具12及びアウタ金具14を弾性連結する状態に、それらに一体加硫接着されたゴム弾性体16と、インナ金具12とは別体で板状をなし、インナ金具12の上端部にかしめにより固定されてインナ金具12とともに上下動し、リバウンド時にストッパ作用をなすリバウンドストッパ金具18とを有している。
フランジ部22の外周端部は全周に亘り図中下向きに湾曲形状で曲げられている。図中24はその曲げ部を表している。
フランジ部22は、周方向の3個所が更に径方向外方へと突出せしめられており、その突出部分が板状の取付部26を成している。
ここで取付ボルト28には、大径の頭部32側にセレーション部34が設けられており、このセレーション部34を固定孔30の内面に食い込ませる状態に固定孔30に固定されている。
アッパーサポート10は、この取付部26において取付ボルト28により車体側に固定される。
第1金具12‐1は、上部の円筒状の小径部38と、下部の円筒状の拡径部40とを有しており、その拡径部40の内側にベアリング42を保持している。
拡径部40は、下端が径方向内向きに折り曲げられてかしめられ、そのかしめによって、ベアリング42が抜止め状態に保持されている。
図中44は、その拡径部40のかしめ部を表している。
第2金具12-2のスカート部48の下端部且つ外周端部は、バウンド側のストッパ作用時のストッパ当り部49を成している。
一方インナ金具12は、リバウンドストッパ金具18ほどには大きな荷重が作用せず、またこのインナ金具12、詳しくは第1金具12-1はプレス加工による板材の絞り加工にて製造されることから、更にはその下端部と、後に述べる上端側の凸係合片58とが折り曲げられ、かしめ加工されることから、変形加工が困難とならないようにリバウンドストッパ金具18よりも軟らかい材料で構成されていることが好ましい。
図示のようにインナ金具12には、その上端面56から且つ周方向において部分的に、リバウンドストッパ金具18の板厚よりも大きく上向きに突出する凸係合片58が設けられている。
ここで凸係合片58は、全周に亘って一定間隔ごとに複数(ここでは6個)設けられている。
凸係合片58は、正面視形状が4角形状をなしており、そして隣接する凸係合片58と58との間に、同じく正面視形状が4角形状をなす凹部60が形成されている。なお、正面視とは、円筒形状を有する第1金具12-1の中心軸に直交する軸直角方向での視図に略等しく、第1金具12-1を周上の一箇所において中心軸と平行に延びる切断線をもって切り開いた展開図を表すものに等しい。
この絞り加工では、周知のとおり深絞り用の成形型(パンチ,ダイス,しわ押えを含む)を用いて板材に対してプレス加工装置を用いた絞り加工を施すことにより、先ず有底の円筒状(カップ形状)に形成する。しかる後に、かかる中間加工品であるカップ形状の成形品における底部を、打抜き加工用の打抜型(ダイス及びパンチを含む)を用いて、同じくプレス加工による打抜き加工により除去することで、最終的に上面が開放形状をなす第1金具12-1が形成される。
尚、拡径部40もまたプレスによる拡径加工で形成される。
切欠凹部66もまた、上記の凸係合片58に対応して全周に亘り互いに等間隔で複数(ここでは6個)設けられている。
尚、径方向の深さは、ここでは凸係合片58の厚みとほぼ同等とされており、更に中心穴62の直径は、インナ金具12の上端部内径と同等とされており、図2に示す組付状態では中心穴62の周面64と、インナ金具12の内周面とは合致した状態となる(図1の部分拡大図参照)。
また、リバウンドストッパ金具18における周方向に隣接した切欠凹部66と66との間の部分は、切欠凹部66を基準として見たとき径方向内方への突出部68となる。
尚、上記中心穴62の直径を、インナ金具12の上端部内周面の直径よりも僅かに大きくし、リバウンドストッパ金具18の中心穴62の周面64が、インナ金具12の内周面よりも僅かに径方向外方に引き込んだ位置としておくこともできる。また、装着条件等に応じて、反対に、リバウンドストッパ金具18の中心穴62の周面64が、インナ金具12の内周面よりも僅かに径方向内方に突出した位置とすることも可能である。
このとき、リバウンドストッパ金具18は、インナ金具12の上端面56を着座面として、そこに下面が着座した状態となり、リバウンドストッパ金具18がその上端面56にて上下方向に位置決め状態に支持される。
この実施形態では、インナ金具12上端部の内径と、リバウンドストッパ金具18の中心穴62の直径とが同径とされているため、リバウンドストッパ金具18は、インナ金具12の上端面56を全肉厚に亘って着座面となして、そこに着座せしめられる。即ち、インナ金具12の上端面56が、軸直角方向に広がる平坦面とされており、その全肉厚の領域に対して、リバウンドストッパ金具18の内周縁部の下面が当接状態で重ね合わされて支持されている。
以上のように各凸係合片58を各切欠凹部66に嵌め合せた上で、次に図7(II)に示すように凸係合片58の、リバウンドストッパ金具18の上面よりも上側に突き抜けた部分を径方向外方に折り曲げて、リバウンドストッパ金具18の上面を押圧する状態にかしめることで、リバウンドストッパ金具18をインナ金具12に固定する。
このとき、図2に示しているように各凸係合片58は、リバウンドストッパ金具18側の各突出部68に対し、あたかも歯車が噛み合ったように周方向に機械的ないし物理的に係合した状態となる。
この嵌合クリアランスは、リバウンドストッパ金具18がインナ金具12に対して周方向にがたつきを生ずる要因となる。
ここでは挿入ガイド面69は傾斜面とされている。
このようにしておけば、凸係合片58の切欠凹部66への挿入性を良好とすることができ、円滑に凸係合片58を切欠凹部66に図中上向きに挿入し圧入することができる。
尚、図8では、凸係合片58の根元部において一定の周方向幅T1 を有する部分の高さ寸法が、切欠凹部66の厚さ寸法と略等しくされていたが、これに限定されない。即ち、一定の周方向幅T1 を有する部分の高さ寸法は、切欠凹部66の厚さ寸法に比して小さくても良いし、大きくても良い。
なお、図9(A)では、挿入ガイド面70が、切欠凹部66の周方向両側縁部における下端角部に対してC面取り形状で形成されていたが、これに限定されない。即ち、かかる挿入ガイド面70は、切欠凹部66の周方向両端面において厚さ方向の全体に亘って延びるテーパ面とされていても良いし、また、湾曲した凸状又は凹状の面形状とされていても良い。
またこの場合において、切欠凹部66に上向きに挿入し嵌め合せた凸係合片58を、径方向外方に折り曲げてかしめる場合の他、径方向内方に折り曲げてかしめるといったことも可能である。
