Abstract
A flange for a torque converter, comprising a first sub-assembly that includes a first hole and second hole located along the first sub-assembly and wherein the first and second hole are configured to facilitate movement of a first pressure path from a transmission input shaft to a piston. The flange for the torque converter also includes a second sub-assembly that includes one or more welds that join a first contact-side of the second sub-assembly to the first sub-assembly, wherein a gap is defined between an area where the second sub-assembly is joined to the first sub-assembly.
Claims19
A flange for a torque converter, comprising:
- a first sub-assembly that includes a first hole and a second hole located along the first sub-assembly and wherein the first and second hole are configured to facilitate movement of a first pressure path from a transmission input shaft to a piston;
- and
- a second sub-assembly that includes one or more welds that join a first contact-side of the second sub-assembly to the first sub-assembly, wherein a gap is defined between an area where the second sub-assembly is joined with the first sub-assembly, and wherein the second sub-assembly is configured to facilitate movement along a second pressure path from the transmission input shaft to piston.
A method of manufacturing a flange for a torque converter, comprising:
- forming one or more holes in a top-portion of a first sub-assembly of the torque converter, wherein the holes are configured to facilitate movement along a first fluid-pressure path from a transmission input shaft to a piston, wherein the first fluid-pressure path is formed along a gap between the first sub-assembly and a second sub-assembly;
- welding a first contact-point and second contact-point of the first sub-assembly and the second sub-assembly, such that the gap is defined between the first contact-point and the second contact-point of the first and second sub-assembly;
- and
- cooling the first sub-assembly and second sub-assembly until the first and second sub-assembly are joined.
A flange for a torque converter, comprising:
- a first sub-assembly that includes a top portion with one or more holes along the top portion;
- and
- a second sub-assembly that includes a plurality of welds that join the second sub-assembly to the first sub-assembly, wherein the second sub-assembly is configured to form a gap between a first weld and a second weld and between the first sub-assembly and the second sub-assembly.
