Abstract
A radial wedge clutch, including: an axis of rotation; a shaft; an outer ring located radially outward of the shaft; a cage radially disposed between the shaft and the outer ring; a plurality of circumferentially aligned wedge plate segments radially disposed between the shaft and the outer ring; at least one resilient element urging the plurality of circumferentially aligned wedge plate segments radially outwardly; and an actuation plate axially displaceable in a first axial direction to engage the cage and rotate the cage and the plurality of circumferentially aligned wedge plate segments.
Claims20
A radial wedge clutch, comprising:
- an axis of rotation;
- a shaft;
- an outer ring located radially outward of the shaft;
- a cage radially disposed between the shaft and the outer ring;
- a plurality of circumferentially aligned wedge plate segments radially disposed between the shaft and the outer ring;
- at least one resilient element urging the plurality of circumferentially aligned wedge plate segments radially outwardly;
- and,
- an actuation plate axially displaceable in a first axial direction to:
- engage the cage;
- and,
- rotate the cage and the plurality of circumferentially aligned wedge plate segments.
A radial wedge clutch, comprising:
- an axis of rotation;
- a shaft;
- an outer ring located radially outward of the shaft;
- a cage radially disposed between the shaft and the outer ring;
- a plurality of circumferentially aligned wedge plate segments radially disposed between the shaft and the outer ring and axially bracketed by the cage;
- at least one resilient element:
- engaged with the cage and the plurality of circumferentially aligned wedge plate segments;
- and,
- urging the plurality of circumferentially aligned wedge plate segments radially outwardly into contact with the outer ring;
- and,
- an actuation plate non-rotatably connected to the shaft, wherein:
- for a connect mode for the radial wedge clutch, the shaft, the plurality of circumferentially aligned wedge plate segments, and the outer ring are non-rotatably connected;
- and,
- to initiate the connect mode:
- the actuation plate is displaceable in a first axial direction to engage the cage and to rotate the cage and the plurality of circumferentially aligned wedge plate segments with respect to the outer ring;
- and,
- the outer ring displaces the plurality of circumferentially aligned wedge plate segments radially inwardly to non-rotatably connect to the shaft.
A radial wedge clutch, comprising:
- an axis of rotation;
- a shaft;
- an outer ring located radially outward of the shaft;
- a cage radially disposed between the shaft and the outer ring;
- a plurality of circumferentially aligned wedge plate segments radially disposed between the shaft and the outer ring and axially bracketed by the cage;
- at least one resilient element:
- engaged with the cage and the plurality of circumferentially aligned wedge plate segments;
- and,
- urging the plurality of circumferentially aligned wedge plate segments radially outwardly into contact with the outer ring;
- and,
- an actuation plate non-rotatably connected to the shaft, wherein:
- for a connect mode for the radial wedge clutch, the shaft, the plurality of circumferentially aligned wedge plate segments, and the outer ring are non-rotatably connected;
- for a disconnect mode for the radial wedge clutch, the shaft is rotatable with respect to the outer ring;
- and,
- to transition from the connect mode to the disconnect mode:
- the actuation plate is displaceable in a second axial direction, opposite the first axial direction, to disengage from the cage;
- the shaft rotates in a second circumferential direction, opposite the first circumferential direction;
- the second ramps slide along the plurality of first ramps in the second circumferential direction;
- and,
- the at least one resilient element displaces the plurality of circumferentially aligned wedge plate segments radially outwardly and out of contact with the shaft.
