  • Patent number: 9284994
    Abstract: A clutched device that includes a pulley, a shaft member, a first one-way clutch having a first wrap spring, and an actuator having an electromagnetic coil and an armature. The first one-way clutch rotationally couples the pulley and the shaft member when the actuator is actuated and rotary power is transmitted from a first one of the pulley and the shaft member to the other one of the pulley and the shaft member in a first rotational direction. A frictional force is applied to the armature when the actuator is activated. The frictional force is configured to resist rotation of the armature to cause the first wrap spring to radially expand into driving engagement with a clutch surface that is coupled to the pulley for common rotation.

  • Patent number: 9267575
    Abstract: A drive train is used at least including an input shaft and an output shaft. A clutch member is rotatable by a clutch shaft about an axis of rotation. The clutch shaft is supported for lateral movement along the axis of rotation to move the clutch member to cooperate with the drive train at a first lateral position to cause the output shaft to turn and to move the clutch member to a second lateral position to disengage the output shaft from rotation of the input shaft. A permanent magnet is supported by one end of the clutch shaft and arranged for receiving an external magnetic biasing force along the axis of rotation to selectively move the clutch member between the first and second lateral positions. A traveling shaft can be used to support a selected gear for movement by the permanent magnet to implement transmission and reversing configurations.

  • Patent number: 9261148
    Abstract: An electromagnetic clutch includes an armature 42 having a rotor contact surface 46a segmented in the radial direction by an annular groove 44 to form a plurality of rings, the groove being formed concentrically with the armature 42 for obstructing magnetic flux; and a rotor 43 having a contact surface, wherein the armature 42 is attracted toward the contact surface of the rotor 43 by magnetic force caused by an electromagnetic coil to couple the armature with the rotor for transmitting power. The armature 42 is formed by the steps of: preparing an armature material 42 with a groove 44 formed thereon, the groove having a width of w1; and narrowing the groove width from w1 to w2 by applying pressure on a pressed portion 47 in a peripheral edge region of the groove 44 to cause plastic flow in a horizontal direction along the material 42.
