Torque converter closure tabs
View Patent ↗A torque converter including a cover with at least one slot located about a periphery and a pump with at least one protrusion located about a periphery of the pump. The protrusion extends axially through the slot and is bent radially about the slot to join the cover and the pump. In some aspects, the converter includes a sealing element disposed between the cover and the pump and the sealing element is selected from the group consisting of an o-ring and a gasket. A method of transferring torque including: inserting at least one peripherally disposed protrusion for one of a pump and cover of a torque converter through at least one peripherally disposed opening in the other of the pump and cover, radially bending the protrusion to clamp the cover and pump, and transmitting torque from the cover to the pump through the protrusion.
1. A torque converter, comprising:
a cover including:
a radially outwardly extending portion forming a radially outer periphery of the cover; and,
a plurality of openings passing through the radially outwardly extending portion; and,
a pump including a plurality of protrusions extending axially from the radially outer periphery of the cover and disposed within the plurality of openings, wherein
each opening in the plurality of openings is enclosed by a respective portion of the radially outwardly extending portion radially disposed between said each opening and the radially outer periphery of the cover; and,
respective portions of the plurality of protrusions are located radially outward of the radially outer periphery of the cover.
2. The torque converter of claim 1 further comprising: a sealing element disposed between said cover and said pump.
3. The torque converter of claim 2 wherein said sealing element is selected from the group consisting of an o-ring and a gasket.
4. The torque converter of claim 1 wherein said plurality of protrusions is bent radially to clamp said pump and said cover.
5. The torque converter of claim 1 wherein said radially outwardly extending portion is integrally formed with said cover.
6. The torque converter of claim 1 further comprising: a support ring circumferentially located about one of said pump or said cover proximate said plurality of protrusions.
7. The torque converter of claim 6 wherein said support ring is in contact with said plurality of protrusions.
8. The torque converter of claim 1 wherein said pump comprises a low carbon steel.
9. The torque converter of claim 1 wherein said pump is formed by stamping.
10. The torque converter of claim 1 wherein said cover is formed by casting.
11. The torque converter of claim 10 wherein said cover is constructed of a material selected from the group consisting of a steel alloy, cast iron, and aluminum.
12. The torque converter of claim 1 wherein said cover is formed by stamping.
13. The torque converter of claim 1 wherein said cover further comprises:
at least one lug integral to said cover; and,
a pilot integral to said cover.
14. The torque converter of claim 1 wherein said cover is arranged to receive torque and to transmit said torque through said plurality of protrusions.
15. A method for transferring torque from a drive unit, comprising:
inserting at least one peripherally disposed protrusion for a pump of a torque converter through at least one peripherally disposed opening in a cover for the torque converter;
radially bending said at least one protrusion to clamp said cover and said pump;
axially bending the at least one protrusion such that a portion of the at least one protrusion is radially outward of the cover; and,
transmitting torque from said cover to said pump through said at least one protrusion, wherein the at least one protrusion extends axially from a radially outwardly facing surface of the pump.
16. A torque converter, comprising:
a cover with a plurality of slots, each slot wholly enclosed by the cover; and,
a pump including a plurality of protrusions, wherein:
the plurality of protrusions:
axially extend from a radially outwardly facing surface of the pump; and,
are disposed in a plurality of openings; and,
the plurality of protrusions include respective distal ends disposed radially outward of the cover and radially aligned with the cover.
