Claims (17)

1. A torque converter comprising:

a plurality of blades; and

a core ring supporting the plurality of blades, the core ring including at least two segments, each segment having two circumferential ends, wherein one of the plurality of blades passes through the circumferential ends.

2. The torque converter as recited in claim 1 wherein two of the segments are continuously connected.

3. The torque converter as recited in claim 2 wherein the segments are continuously connected at two of the circumferential ends.

4. The torque converter as recited in claim 1 wherein one of the circumferential ends of one segment includes a compressed portion, formed to fit another circumferential end of another segment.

5. The torque converter as recited in claim 1 wherein the segments have a plurality of blade tab slots.

6. The torque converter as recited in claim 1 wherein a number of the blades is divisible by a number of the segments to form an integer.

7. The torque converter as recited in claim 5 wherein the blades have tabs, the blade tabs bending over the core ring.

8. The torque converter as recited in claim 1 wherein the segments are stamped low carbon steel.

9. The torque converter as recited in claim 1 wherein the segments are brazed.

10. A torque converter core ring comprising:

a core ring for supporting a plurality of blades, the core ring including at least two segments, each segment having two circumferential ends, wherein one of the blades passes through the circumferential ends.
