Abstract
An actuator for externally manipulating a clutch within a machine rotatable about an axis is provided with a driving unit including a plurality of magnetic coils arranged around the axis, each of the coils being arranged to generate a magnetic flux in a direction parallel to the axis; an armature disposed coaxially with the axis and opposed axially to the driving unit, the armature being movable axially; and a plunger coupled with the armature to transmit axial motion to the clutch.
Claims9
An actuator for externally manipulating a clutch within a differential rotatable about an axis, comprising:
- a driving unit including a plurality of magnetic coils arranged around the axis, each of the coils being arranged to generate a magnetic flux in a direction parallel to the axis;
- an armature disposed coaxially with the axis and opposed axially to the driving unit, the armature being movable axially and attracted toward the driving unit;
- a leg axially projecting from the clutch and passing through a through-hole of a casing of the differential with the leg exposed through the through-hole to an exterior of the casing;
- and
- a plunger coupled with the armature and the leg to transmit axial motion to the clutch, wherein the clutch includes a clutch member that has dog teeth and the leg is formed as part of a unitary body with the clutch member.
