Abstract
Description
減速機構3は、複数の歯車等から成る遊星歯車減速機構11で構成される。図3に示すように、遊星歯車減速機構11は、リングギヤ12と、サンギヤ13と、複数の遊星ギヤ14と、遊星ギヤキャリア15から構成される。
運動変換機構6は、駆動用モータ2の出力軸2aと平行な軸上に配置されるボールねじ20で構成される。なお、運動変換機構6は、ボールねじ20に限らず、滑りねじ装置であってもよい。ただし、回転トルクを低減して、駆動用モータ2を小型化する観点からすれば、ボールねじ20の方が好適である。
図4に示すように、目標値が制御装置80に送られると、制御装置80のコントローラ81から駆動用モータ2に制御信号が送られる。なお、この目標値は、例えば、車両上位のECUに操作量が入力された際に、その操作量に基づいてECUが演算したストローク値である。
図5に示すように、この場合は、操作対象装置に圧力センサ83が設けられている。車両上位のECUに操作量が入力されると、ECUは要求される目標値(圧力指令値)を演算する。この目標値が制御装置80に送られ、コントローラ81から駆動用モータ2に制御信号が送られると、駆動用モータ2は回転駆動を開始する。これにより、ボールねじ軸22が前進し、ボールねじ軸22の先端部側(アクチュエータヘッド側)に配置される操作対象装置が加圧操作される。
図8に示す比較例に係る電動アクチュエータ100は、上記本発明の実施形態と同様に、駆動用モータ102、減速機構としての遊星歯車減速機構111、伝達ギヤ機構としてのドライブギヤ116およびドリブンギヤ117、運動変換機構としてのボールねじ120を備えているが、本発明の実施形態に対して特にドライブギヤ116を支持する構成が異なっている。
