  • Driven component with clutch for selective operation of component
    Patent number: 9038799
    Abstract: A component, such as an engine accessory for an automotive engine, that has clutch with a helical clutch coil and an axially movable armature. The helical clutch coil is normally engaged so as to transmit rotary power between a driving member and a driven member. The armature can be moved to apply a force to a tang of the helical clutch coil that causes the helical clutch coil to disengage to an extent where full rotary power is not passed through the clutch to drive the component.
    Type: Grant

  • Driven accessory with low-power clutch for activating or de-activating same
    Patent number: 8851258
    Abstract: A driven accessory having a clutch that permits selective operation of an accessory portion. The clutch employs rotational inertia to control driving engagement of a wrap spring to an interior clutch surface on a drive member and/or driving disengagement of the wrap spring from the interior clutch surface.

  • Clutch for selectively driving an accessory
    Patent number: 8627935
    Abstract: A clutch assembly having a driver, an output member, a clutch spring, an armature and an actuator. The clutch spring includes a plurality of coils that are configured to be drivingly engaged with the driver. The clutch spring further includes first and second ends. The first end is configured to drivingly engage the output member to facilitate the transmission of rotary power from the driver, through the clutch spring and into the output member. The second end is engaged to the armature. The actuator is selectively operable for rotating the armature relative to the driver in a rotational direction opposite a predetermined rotational direction in which the driver is driven to thereby initiate at least partial disengagement of the coils of the clutch spring from the driver.

  • DRIVEN COMPONENT WITH CLUTCH FOR SELECTIVE OPERATION OF COMPONENT
    Publication number: 20130313068
    Abstract: A component, such as an engine accessory for an automotive engine, that has clutch with a helical clutch coil and an axially movable armature. The helical clutch coil is normally engaged so as to transmit rotary power between a driving member and a driven member. The armature can be moved to apply a force to a tang of the helical clutch coil that causes the helical clutch coil to disengage to an extent where full rotary power is not passed through the clutch to drive the component.
