Abstract
A driven accessory that includes an input member, a cover, an output member, a clutch and a clutch actuator. The input member is rotatable about an axis and has a hub, an outer rim, and a radially extending web that couples the hub to the outer rim. The cover is coupled to the input member for common rotation about the axis and cooperates with the input member to define a clutch cavity. The clutch is received in the clutch cavity and selectively transmits rotary power between the input member and the output member. The clutch actuator is selectively operable to change the operational state in which the clutch operates. The clutch actuator has an electromagnetic coil that is disposed outside the clutch cavity. The hub is disposed along the axis between the clutch and the electromagnetic coil.
Claims16
A driven accessory comprising:
- an input member having a hub, an outer rim, and a radially extending web that couples the hub to the outer rim, the input member being rotatable about an axis;
- a cover coupled to the input member for common rotation about the axis, the cover cooperating with the input member to define a clutch cavity;
- an output member that is rotatable about the axis independently of the input member;
- a clutch received in the clutch cavity, the clutch being operable in a plurality of operational states including a first operational state, in which the output member is decoupled from the input member, and a second operational state in which the output member is coupled to the input member for common rotation;
- a clutch actuator that is selectively operable to change the operational state in which the clutch operates, the clutch actuator having an electromagnetic coil that is disposed outside the clutch cavity, wherein the hub is disposed along the axis between the clutch and the electromagnetic coil;
- a housing;
- and
- first and second bearings that are mounted coaxially to the housing, the first bearing supporting the input member for rotation relative to the housing, the second bearing supporting the output member for rotation relative to the housing.
