Description
本実施形態に係る減衰力調整式緩衝器1は、車体と台車との間に縦置き状態で取り付けられる鉄道車両用上下動ダンパとして採用される。なお、本実施形態では、縦置き状態で取り付けられる鉄道車両用上下動ダンパを例として示すが、左右動ダンパや、ヨーダンパに用いてもよい。また、本実施形態に係る減衰力調整式緩衝器1を、自動車のダンパとして採用してもよい。
図2に示すように、減衰力発生手段25は、パイロット型のメインバルブ32、及びフェイル時に作動するフェイルバルブ33等を備えたバルブブロック35と、メインバルブ32の開弁圧力を制御するソレノイド駆動の圧力制御弁であるパイロットバルブ36を作動させるソレノイドブロック37と、を備えている。図1に示すように、これらソレノイドブロック37及びバルブブロック35は同軸上に配置され、外筒3の軸方向と直交する方向に沿って配置されている。図2に示すように、これらバルブブロック35とソレノイドブロック37とは、円筒状のケース40内に配置されている。ケース40は、バルブブロック35を収容するバルブケース41と、ソレノイドブロック37を収容するソレノイドケース42とを第1の実施形態に係るかしめ部45Aによってかしめ固定して構成される。ソレノイドブロック37が、一端側で、外筒3から径方向最も外側に配置され、バルブブロック35が、他端側で、外筒3に近い側に配置されている。なお、ケース40が筒部材に相当する。
その後、バルブケース41の薄壁部47の一端部を、ソレノイドケース42の径方向外方を軸方向に沿って一端側から他端側に向かって移動する、図示しないかしめ治具により、ケース40の内方に向けて折り曲げる。すると、バルブケース41の薄壁部47の一端部における突設部50を除く内周面が、ソレノイドケース42のかしめ用溝部150Aに設けた傾斜面152Aに当接する。このとき、薄壁部47に設けた突設部50の内周面は、かしめ用溝部150Aの傾斜面152Aには当接せずに浮いた状態となる。これにより、ソレノイドケース42の他端がバルブケース41内に、第1の実施形態に係るかしめ部45Aによりかしめ固定される。
まず、ピストンロッド6の伸び行程時には、シリンダ2内のピストン5の移動によって、ピストン5の逆止弁13が閉じ、ディスクバルブ14の開弁前では、シリンダ上室2A側の油液が加圧されて、油液が通路22及び環状通路21を通り、セパレータチューブ20の接続口23から減衰力発生手段25の通路部材60の連通路63に流入する。その後、油液が減衰力発生手段25を通過することで減衰力が発生されてリザーバ4に戻る。
この伸び行程時には、ピストン5が移動した分の油液は、リザーバ4からベースバルブ10の通路15を経由して逆止弁17を開いて、シリンダ下室2Bへ流入する。なお、シリンダ上室2Aの圧力がピストン5のディスクバルブ14の開弁圧力に達すると、ディスクバルブ14が開いて、シリンダ上室2Aの圧力を、通路11を介してシリンダ下室2Bへリリーフすることにより、シリンダ上室2Aの過度の圧力の上昇を防止する。
