Abstract | To provide a clutch device capable of maintaining, with a simple configuration, the state of a clutch.SOLUTION: A motor 20 comprises: a stator 21 which is fixed to a housing 12; and a rotor 23 which is provided so as to be rotatable relative to the stator 21. When supplied with electric power, the motor 20 can output torque. A reduction gear 30 can output the torque of the motor 20 after reducing it. A ball cam 2 has: a driving cam 40 which is rotated relative to the housing 12 by the torque from the reduction gear 30; and a driven cam 50 which moves relative to the housing 12 in the axial direction. A clutch 70 permits torque transmission when in an engaged state where it is engaged, and blocks torque transmission when in a disengaged state where it is not engaged. When applied with force in the axial direction from the driven cam 50, a state changing part 80 can change the state of the clutch 70. Cogging torque generated between the rotor 23 and the stator 21 is set to be such a degree that the rotor 23 can rest at an arbitrary rotational position with respect to the stator 21.SELECTED DRAWING: Figure 1
【課題】簡単な構成でクラッチの状態を維持可能なクラッチ装置を提供する。【解決手段】モータ20は、ハウジング12に固定されたステータ21、ステータ21に対し相対回転可能に設けられたロータ23を有し、電力の供給によりトルクを出力可能である。減速機30は、モータ20のトルクを減速して出力可能である。ボールカム2は、減速機30からのトルクによりハウジング12に対し相対回転する駆動カム40、ハウジング12に対し軸方向に相対移動する従動カム50を有する。クラッチ70は、係合している係合状態のとき、トルクの伝達を許容し、係合していない非係合状態のとき、トルクの伝達を遮断する。状態変更部80は、従動カム50から軸方向の力を受け、クラッチ70の状態を変更可能である。ロータ23とステータ21との間に生じるコギングトルクは、ロータ23がステータ21に対し任意の回転位置で静止可能な程度の大きさに設定されている。【選択図】図1 |
