Claims (7)
- 1.全て共通の中心軸線上にある入力軸と、スリーブと、被動部材と、全体が機 械的に作動する心決め機構とを具え、この心決め機構は、支持体と、2個、又は それ以上の転動素子とを具え、各転動素子を1対の対向する切欠形成素子間に配 置し、この切欠形成素子の内の第1切欠形成素子を前記入力軸に固着し、又は一 体に形成し、他方の第2切欠形成素子を前記第1切欠形成素子に対し接近又は離 間するよう移動でき前記心決め機構の中心軸線の周りに回転できるよう前記支持 体に支持し、前記支持体を前記スリーブ又は前記被動部材に取り付ける取付け手 段を設け、それぞれ前記転動素子を各前記第1切欠素子と端前記第2切欠素子と の間に拘束するようこの第2切欠素子を第1切欠素子に押圧するばね手段を設け 、これにより前記入力軸と前記スリーブ又は前記被動部材との間に止め作用を生 ぜしめ、これにより所定の限界値を越える入力トルクが加わった時のみ前記入力 軸と前記スリーブ又は前記被動部材との間に相対回転を生ぜしめる動力操向装置 の回転弁において、前記心決め機構の前記スリーブ又は前記被動部材への組立て 後、前記支持体の前記スリーブ又は前記被動部材への取付けを実施し、前記組立 て後で前記取付け前には前記回転弁の中心軸線に垂直な平面内で前記スリーブ又 は前記被動部材に対し半径方向及び回転方向の両方向に僅かな角度にわたり前記 支持体が自由な浮動状態になるよう前記支持体と前記取付け手段とを構成配置し 、これにより各前記転動素子とそのそれぞれの対向する切欠形成素子との相互面 に同時に二重拘束の4個の線接触、又は4個の点接触が生ずる力平衡位置を前記 支持体が前記ばね手段の押圧を受けて占め、これにより前記取付け後、各前記転 動素子とそのそれぞれの対をなす対向する切欠形成素子とによって生ずる止め作 用を同期して発生することを特徴とする動力操向装置の回転弁。
- 2.全て共通の中心軸線上にある入力軸と、スリーブと、被動部材と、全体が機 械的に作動する心決め機構とを具え、この心決め機構は、支持体と、2個、又は それ以上の転動素子とを具え、各転勤素子を1対の対向する切欠形成素子間に配 置し、この切欠形成素子の内の第1切欠形成素子を前記入力軸に固着し、又は一 体に形成し、他方の第2切欠形成素子を前記第1切欠形成素子に対し接近又は離 間するよう移動でき前記心決め機構の中心軸線の周りに回転できるよう前記支持 体に支持し、前記支持体を前記スリーブ又は前記被動部材に取り付ける取付け手 段を設け、それぞれ前記転動素子を各前記第1切欠素子と各前記第2切欠素子と の間に拘束するようこの第2切欠素子を第1切欠素子に押圧するばね手段を設け 、これにより前記入力軸と前記スリーブ又は前記被動部材との間に止め作用を生 ぜしめ、これにより所定の限界値を越える入力トルクが加わった時のみ前記入力 軸と前記スリーブ又は前記被動部材との間に相対回転を生ぜしめる動力操向装置 の回転弁において、ねじ、ボルト、リベット、又はその他の軸線方向固定具によ って前記支持体を前記スリーブ、又は前記被動部材に取り付けるのを容易にする 取付け孔を前記支持体に設け、前記支持体を前記スリーブ、又は前記被動部材に 取り付ける以前に前記回転弁の前記中心軸線に垂直な平面内で前記スリーブ、又 は前記被動部材に対し前記支持体が半径方向及び回転方向に僅かな角度にわたり 浮動できるように前記軸線方向固定具の直径に対する間隙を前記取付け孔に設け 、これにより前記支持体を取り付けた後、前記2個、又はそれ以上の転動素子と そのそれぞれの対向する切欠形成素子とによって止め作用を同期して生ずるよう 前記ばね手段の押圧作用を受けて前記支持体が力平衡位置を占めることを特徴と する動力操向装置の回転弁。
- 3.前記転動素子を円筒形に構成し、前記切欠形成素子のプリズム状の輪郭に線 接触させる請求の範囲1、又は2に記載の回転弁。
- 4.前記転動素子の軸線を前記回転弁の中心軸線に平行に配置した請求の範囲3 に記載の回転弁。
- 5.前記ばね手段をC字状ばねにした前記請求の範囲のいずれか1項に記載の回 転弁。
- 6.前記ばね手段を板ばねにした請求の範囲1〜5のいずれか1項に記載の回転 弁。
- 7.更に前記回転弁に捩じり棒を設け、前記取付け後生ずる前記止め作用の同期 作用によって、所定の限界値を越えない入力トルクに対しては前記捩じり棒の作 用が検知されない状態に留める請求の範囲1〜6のいずれか1項に記載の回転弁 。
