Claims (4)
- 螺子ナット内に回転自在に螺合される螺子軸と、螺子軸に連結されるモータとを備え、モータの電磁力で螺子ナットと螺子軸の軸方向の相対移動を抑制する電磁緩衝器において、螺子軸とモータとの間に両者間の伝達トルクを変更する電磁クラッチを備え、当該電磁クラッチへの電流供給量を制御してモータの慣性モーメントによる減衰力を制御することを特徴とする電磁緩衝器。
- 支持部材に支持される螺子ナット内に回転自在に螺合される螺子軸と、螺子軸に連結されるモータとを備え、モータの電磁力で螺子ナットと螺子軸の軸方向の相対移動を抑制する電磁緩衝器において、支持部材と螺子ナットとの間に両者間の伝達トルクを変更する電磁クラッチを備え、当該電磁クラッチへの電流供給量を制御してモータの慣性モーメントによる減衰力を制御することを特徴とする電磁緩衝器。
- 電磁クラッチは、螺子軸を回転させるトルクもしくはモータの発生する電磁力によるモータのシャフトを回転させるトルクが所定のトルク以上となったときに、上記トルクの伝達を抑制もしくは解除することを特徴とする請求項1に記載の電磁緩衝器。
- 電磁クラッチは、螺子ナットに作用するトルクが所定のトルク以上となったときに支持部材への上記トルクの伝達を抑制もしくは解除することを特徴とする請求項2に記載の電磁緩衝器。
