Abstract
A stator assembly of a torque converter includes a stator having circumferentially arranged blades, an inner ring, and projections circumferentially arranged around the inner ring and extending radially inward therefrom. An annular plate is circumscribed by the inner ring and has a plurality of attachment portions circumferentially arranged around an outer surface of the plate. Each of the attachment portions engages with an associated one of the projections and has a pair of spaced anti-rotation tabs that define a receptacle. The receptacle receives the associated one of the projections to prevent relative rotation between the stator and the plate.
Claims20
A stator assembly of a torque converter comprising:
- a stator including circumferentially arranged blades, an inner ring, and projections circumferentially arranged around the inner ring and extending radially inward therefrom;
- and
- an annular plate circumscribed by the inner ring and including:
- opposing sides oriented radially,
- an outer circumferential surface extending between the sides, and
- a plurality of attachment portions circumferentially arranged around the outer circumferential surface of the plate, each of the attachment portions having a central tab extending radially outward from the outer circumferential surface and having a pair of spaced anti-rotation tabs flanking the central tab and including portions disposed axially forward of a face of the central tab to define a receptacle over the central tab and between the anti-rotation tabs, wherein each of the attachment portions receives an associated one of the projections in the receptacle with the face of the central tab disposed against a face of the associated projection to prevent relative movement between the stator and the plate.
A method of assembling a stator assembly of a torque converter comprising:
- fabricating an annular side plate including a plurality of attachment portions circumferentially arranged around an outer surface of the plate, each of the attachment portions having a pair of spaced anti-rotation tabs;
- inserting the plate into a stator, that includes a hub and blades circumferentially arranged around the hub, such that the hub circumscribes the plate;
- and
- staking the stator at each of the attachment portions such that material of the hub flows between the anti-rotation tabs to rotationally fix the stator and the plate.
A stator assembly of a torque converter comprising:
- a stator including an inner ring and circumferentially arranged blades;
- and
- an annular plate including opposing faces, an outer circumferential surface extending between the faces, and teeth formed on the outer surface, wherein the plate is disposed within the inner ring with the teeth penetrating into the inner ring to attach the plate to the stator.
