Abstract
減衰力調整式油圧緩衝器1の電磁式減衰力調整装置17を、減衰力を発生する減衰力調整バルブ18と発生減衰力を可変に調整するソレノイド33とにより構成する。ソレノイド33は、通電により磁力を発生するコイル39と、コイル39の内周側に配され、軸方向へ移動可能に設けられる可動鉄心43と、可動鉄心43を吸引するアンカ部材40等を備える。可動鉄心43は、軸部44が固定される固定孔43A1が設けられた厚肉筒部43Aと内周面がテーパ状に拡開されたテーパ筒部43Bとにより構成されている。固定孔43A1の周囲には、作動流体を可動鉄心43の軸方向に流通させる凹部43A2が形成されている。
Description
また、上述した実施の形態では、可動鉄心43を挟んで固定鉄心40とは反対側に位置する軸部44の端部と、該端部を覆うように形成された背圧室形成部材46との間に形成される背圧室47と、背圧室形成部材46の内周側と可動鉄心43との間に設けられ軸部44を軸方向に変位可能に支持する第2の軸受45Bを設ける構成を示した。しかし、本発明はこれに限るものではなく、軸部44の支持は、可動鉄心43と第1の軸受45Aとで行い、背圧室形成部材46、背圧室47、第2の軸受45Bを用いることなく構成するようにしてもよい。
第3の態様としては、第1または第2の態様において、前記厚肉筒部は、前記固定孔の周囲に位置して径方向に窪んで形成され前記可動鉄心の軸方向に貫通して延び、前記作動流体を軸方向に流通させる凹部を有している。
本発明の一実施形態に係るソレノイドは、通電により磁力を発生するコイルと、前記コイルの内周側であって、軸方向へ移動可能に設けられる可動鉄心と、前記可動鉄心と軸方向に対向し前記コイルの内周側に設けられる固定鉄心と、前記可動鉄心および前記固定鉄心の内周側を軸方向に伸長して設けられ、前記可動鉄心と一体に変位する軸部と、を備え、前記固定鉄心は、前記可動鉄心側に外周面が該固定鉄心側に向かうほど外径寸法が大きくなる方向に傾斜したテーパ面状となった環状のコニカル部を有し、前記可動鉄心は、前記固定鉄心と軸方向で対向する厚肉筒部と、該厚肉筒部から前記軸部の他端部側に向けて軸方向に延び内周面がテーパ状に拡開されたテーパ筒部とにより構成され、前記コニカル部の軸方向長と比して、前記厚肉筒部の軸方向長が長いことを特徴としている。
