Torque converter lug
View Patent ↗A lug for a torque converter includes a first radial segment, a second radial segment, and an axially extending connector segment. The first radial segment has a first aperture and respective first and second circumferential ends. The second radial segment has a second aperture aligned with the first aperture, a third circumferential end fixed to the first circumferential end, and a fourth circumferential end fixed to the second circumferential end. The axially extending connector segment joins the first and second radial segments. In an example embodiment, a pre-formed blank for the lug includes a line of symmetry passing through the connector segment.
1. A lug for a torque converter comprising:
a first radial segment with a first aperture and respective first and second circumferential ends;
a second radial segment with a second aperture aligned with the first aperture, a third circumferential end fixed to the first circumferential end via a first weld, and a fourth circumferential end fixed to the second circumferential end via a second weld;
an axially extending connector segment joining, the first and second radial segments; and;
wherein the first and third circumferential ends or the second and fourth circumferential ends include respective radial lengths, and the first or second weld extends along the entire radial length.
2. The lug of claim 1 wherein a pre-formed blank for the lug includes a line of symmetry passing through the connector segment.
3. The lug of claim 1 wherein the first and second apertures include a continuous thread arranged for receiving a fastener.
4. The lug of claim 1 wherein the first circumferential end is aligned with the third circumferential end or the second circumferential end is aligned with the fourth circumferential end.
5. The lug of claim 1 wherein a circumferential length of the first or second radial segment is greater than a circumferential length of the connector segment.
6. The lug of claim 1 wherein the lug is manufactured from sheet metal.
7. A cover assembly for a torque converter comprising:
a cover shell;
at least one sheet metal lug including:
a radially outer axial connector portion; and,
first and second radial portions fixed together at the radially outer axial connector portion, the first radial portion having a first aperture and respective first and second circumferential ends, the second radial portion having a second aperture and respective third and fourth circumferential ends, and the second aperture is aligned with the first aperture;
a first weld fixing the first and third circumferential ends together and to the cover shell; and,
a second weld fixing the second and fourth circumferential ends together and to the cover shell; and,
wherein the first and third circumferential ends or the second and fourth circumferential ends include respective radial lengths, and the first or second weld extends along the entire radial length.
8. The cover assembly of claim 7 wherein the first and third circumferential ends or the second and fourth circumferential ends are aligned.
9. The cover assembly of claim 7 wherein the first or second apertures are for receiving a fastener for connecting the cover assembly to an engine flexplate.
10. The cover assembly of claim 7 wherein at least a portion of the first or second weld extends circumferentially from the respective first or second circumferential end.
11. The cover assembly of claim 7 wherein the cover shell includes a radial surface and the at least one sheet metal lug is fixed to the radial surface.
