Abstract
In an aspect, a clutched device is provided, and includes an input member, an output member, a one-way clutch that can operatively connect the input member to the output member, and a motor including a stator and a rotor. The rotor is connected for rotation with a portion of the one-way clutch. The stator is operable to apply a first magnetic driving force to cause movement of the portion of the one-way clutch in a first rotational direction to increase a force of engagement between the input and output members. The stator is operable to apply a second magnetic driving force to cause movement of the portion of the one-way clutch to disengage the input and output members from each other.
Claims12
A clutched device for association with an engine, comprising:
- an input member that is rotatable via an endless drive member that is driven by the engine;
- an output member;
- a wrap spring clutch that can operatively connect the input member to the output member;
- and
- a rotary motor including a stator and a rotor, wherein the rotor is connected for rotation with a portion of the wrap spring clutch, wherein the stator is operable to apply a first magnetic driving force to drive rotary movement of the rotor, which in turn drives rotary movement of the portion of the wrap spring clutch in a first rotational direction to increase a force of engagement between the input and output members, wherein the stator is operable to apply a second magnetic driving force to cause movement of the portion of the wrap spring clutch to disengage the input and output members from each other.
