Description
【０００１】[0001]
本考案は車両等に用いられる油圧緩衝器のスプリングシートに関し、例えば懸 架ばねの下端部を支承するロアスプリングシートに関する。 The present invention relates to a spring seat for a hydraulic shock absorber used in a vehicle or the like, for example, a lower spring seat that supports a lower end portion of a suspension spring.
【０００２】[0002]
一般に、車両等に用いられる油圧緩衝器としては、アウタチューブの外周面に ロアスプリングシートを設けて、このロアスプリングシートで懸架ばねの下端部 を支承するようにしている。そして、図５に示すようにロアスプリングシート１ ０１には懸架ばねの下端１０２を支承する部分にプレス成形で段差部１０１ａを 形成し、懸架ばねの軸廻りの位置決めを行なうようにしている。 Generally, as a hydraulic shock absorber used in a vehicle or the like, a lower spring seat is provided on the outer peripheral surface of the outer tube, and the lower spring seat supports the lower end of the suspension spring. As shown in FIG. 5, a step portion 101a is formed in the lower spring seat 101 at a portion supporting the lower end 102 of the suspension spring by press molding so that the suspension spring can be positioned around its axis.
【０００３】[0003]
しかしながら、上述した油圧緩衝器のスプリングシートにあっては、スプリン グシート１０１の段差部１０１ａを塑性加工にて成形する際にＲ部１０３が形成 されるため、懸架ばねの下端１０２の先端を段差部１０１ａに突き当てて位置決 め使用とすると、図６に示すように懸架ばねの最下端１０２がＲ部１０３に乗り 上げてしまい正確な位置決めができない。 However, in the above-described spring seat of the hydraulic shock absorber, since the R portion 103 is formed when the step portion 101a of the spring seat 101 is formed by plastic working, the tip of the lower end 102 of the suspension spring is formed at the step portion. When it is used for positioning by abutting against 101a, the lowest end 102 of the suspension spring rides on the R portion 103 as shown in FIG. 6, and accurate positioning cannot be performed.
【０００４】 そこで、懸架ばねの組付けの際には、懸架ばねの最下端とスプリングシートの 段差部との距離ｘをできるだけ近づけること及び乗り上げないことという規制を 設けて製造しているが、その具体的な判定基準は作業者に任さざるを得ず、生産 性を阻害するとともに品質面でも安定しない。Therefore, when assembling the suspension spring, the suspension spring is manufactured with the restriction that the distance x between the lowermost end of the suspension spring and the stepped portion of the spring seat should be as short as possible and that the rider should not climb up. Workers have no choice but to decide specific criteria, which hinders productivity and is not stable in terms of quality.
【０００５】[0005]
上記課題を解決すべく本考案は、懸架ばねの最下端を支承するスプリングシー トの懸架ばねの端部の最先端部に対応する部分に凹部又は切欠き部を形成した。 In order to solve the above problems, the present invention forms a recess or notch in a portion of the spring sheet that supports the lowermost end of the suspension spring, corresponding to the most distal end of the suspension spring.
【０００６】[0006]
スプリングシートには懸架ばねの最先端部の座面となる部分に凹部又は切り欠 き部が形成されるために、座面となる部分にプレス成形によるＲ部が形成されな くなり、懸架ばねの乗り上げを防止できる。 Since the recessed portion or notch is formed in the seat portion at the most distal end of the suspension spring in the spring seat, the R portion formed by press molding is not formed in the seat surface portion. Can be prevented from riding.
【０００７】[0007]
以下に本考案の実施例を添付図面に基づいて説明する。ここで、図１は本考案 に係るスプリングシートを備えた油圧緩衝器の部分断面図、図２は同緩衝器の要 部拡大図、図３は図２の斜視図である。 Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a partial sectional view of a hydraulic shock absorber provided with a spring seat according to the present invention, FIG. 2 is an enlarged view of a main part of the shock absorber, and FIG. 3 is a perspective view of FIG.
【０００８】 油圧緩衝器のシリンダ（アウタチューブ）１内には上方からピストンロッド２ を挿通し、このピストンロッド２の上端部がアッパースプリングシート３及びイ ンナマウントベース４にナット５で固定されている。また、アッパースプリング シート３の内側にはストッパラバー６が設けられ、インナマウントベース４はマ ウントラバー７を介して車体側部材であるアウタマウントベース８に取付けられ ている。A piston rod 2 is inserted from above into a cylinder (outer tube) 1 of the hydraulic shock absorber, and an upper end portion of the piston rod 2 is fixed to an upper spring seat 3 and an inner mount base 4 with a nut 5. There is. Further, a stopper rubber 6 is provided inside the upper spring seat 3, and the inner mount base 4 is attached to an outer mount base 8 which is a vehicle body side member via a mount bar 7.
【０００９】 そして、アッパースプリングシート３とシリンダ１外周面に固着したロアスプ リングシート１０との間に懸架ばね１１を介設し、この懸架ばね１１とアッパー スプリングシート３との間でダストカバー１２の上端部を挟持している。A suspension spring 11 is provided between the upper spring seat 3 and the lower spring seat 10 fixed to the outer peripheral surface of the cylinder 1, and the dust cover 12 is provided between the suspension spring 11 and the upper spring seat 3. The upper end is clamped.
【００１０】 一方、前記ロアスプリングシート１０には、懸架ばね１１の下端部１１Ａを支 承するフランジ部１３を形成し、このフランジ部１３には図２及び図３に示すよ うに懸架ばね１１の下端部１１Ａの最先端部１１ａに対応する部分に凹部１３ａ を形成し、立ち上がり部１３ｂを成形するために生じるＲ部１３ｃが懸架ばね１ １の最先端部１１ａの座面より下側になるようにしている。On the other hand, the lower spring seat 10 is formed with a flange portion 13 for supporting the lower end portion 11A of the suspension spring 11, and the flange portion 13 is provided with a flange portion 13 of the suspension spring 11 as shown in FIGS. The recessed portion 13a is formed in a portion of the lower end 11A corresponding to the most distal end 11a, and the R portion 13c generated to form the rising portion 13b is below the seating surface of the most distal end 11a of the suspension spring 11. I have to.
【００１２】 以上のように構成したので、組立て時に、懸架ばね１１の下端部１１Ａを図２ に示すように矢印方向にロアスプリングシート１０のフランジ部１３の立ち上が り部１３ｂに意識的にぶつけることによって、懸架ばね１１の最先端部１１ａは フランジ部１３の凹部１３ａ上に位置する。With the above-described structure, the lower end 11A of the suspension spring 11 is consciously attached to the rising portion 13b of the flange portion 13 of the lower spring seat 10 in the arrow direction as shown in FIG. 2 during assembly. By hitting, the most distal end portion 11a of the suspension spring 11 is located on the concave portion 13a of the flange portion 13.
【００１３】 このとき、前述のとおり、フランジ部１３の立ち上がり部１３ｂのＲ部１３ｃ は懸架ばね１１の最先端部１１ａより下側に位置するので、最先端部１１ａがＲ 部１３ｃに乗り上げるということがなくなる。したがって、組立てが簡単になり 、生産性が向上するとともに、正確な位置決めが行なえるので一定のばね特性が 得られる。At this time, as described above, since the R portion 13c of the rising portion 13b of the flange portion 13 is located below the tip end portion 11a of the suspension spring 11, the tip end portion 11a rides on the R portion 13c. Disappears. Therefore, assembling is simplified, productivity is improved, and accurate positioning can be performed, so that a constant spring characteristic is obtained.
【００１４】 上記実施例ではロアスプリングシート１０のフランジ部１３に凹部１３ａを形 成したが、図４に示すように懸架ばね１１の最先端部１１ａを受ける部分に切欠 き部１３ｄを形成して、懸架ばね１１の最先端部１１ａが乗り上げるＲ部１３ｃ をなくすことによっても、上記実施例と同様の効果が得られる。In the above-described embodiment, the recess 13a is formed in the flange portion 13 of the lower spring seat 10, but as shown in FIG. 4, the notch portion 13d is formed in the portion that receives the most distal end portion 11a of the suspension spring 11. Also, by eliminating the R portion 13c on which the most distal end portion 11a of the suspension spring 11 rides, the same effect as in the above embodiment can be obtained.
【００１５】[0015]
以上に説明したように本考案によれば、懸架ばねの端部を支承するスプリング シートの懸架ばねの最先端部に対応する部分に凹部又は切欠き部を形成したので 、位置決めの際に懸架ばねの乗り上げを簡単に防止できて、生産性の向上及び品 質の安定化を図れる。 As described above, according to the present invention, the recess or notch is formed in the portion corresponding to the most distal end of the suspension spring of the spring seat that supports the end of the suspension spring. It is possible to easily prevent the vehicle from riding, improve productivity and stabilize quality.
