TURBINE ASSEMBLY FOR A TORQUE CONVERTER INCLUDING A TAB PLATE AND TURBINE SHELL BRAZED TOGETHER AND METHOD OF FORMING
A turbine assembly is provided. The turbine assembly includes a turbine shell and a tab plate connected to the turbine shell, the turbine shell and the tab plate being brazed together. A method of forming a turbine assembly impeller is also provided. The method includes aligning a tab plate with a turbine shell with a braze material therebetween and brazing the tab plate and turbine shell together by melting the braze material.
1 . A turbine assembly comprising:
a turbine shell; and
a tab plate connected to the turbine shell, the turbine shell and the tab plate being brazed together.
2 . The turbine assembly as recited in claim 1 further comprising elastic dampers, the tab plate arranged for driving the elastic dampers.
3 . The turbine assembly as recited in claim 2 wherein the elastic dampers are arc springs.
4 . The turbine assembly as recited in claim 2 further comprising a retainer supporting the elastic dampers.
5 . The turbine assembly as recited in claim 1 wherein the turbine shell and tab plate are brazed together by a braze material, the braze material extending between an outer surface of the turbine shell and an inner surface of the tab plate.
6 . The turbine assembly as recited in claim 5 wherein the turbine shell includes at least one hole passing therethrough, the braze material surrounding the hole.
7 . The turbine assembly as recited in claim 6 further comprising a turbine core ring, the at least one hole being radially outside of the turbine core ring.
8 . The turbine assembly as recited in claim 1 further comprising a driven component, the tab plate arranged for circumferentially driving the driven component.
9 . A torque converter comprising the turbine assembly as recited in claim 1 .
10 . A method of forming a turbine assembly impeller comprising:
aligning a tab plate with a turbine shell with a braze material therebetween; and
brazing the tab plate and the turbine shell together by melting the braze material.
11 . The method as recited in claim 10 wherein the turbine shell includes a hole extending between an inner surface and an outer surface thereof, the brazing including applying the braze material into the hole.
12 . The method as recited in claim 11 wherein the brazing further includes heating the braze material such that a capillary action pulls the braze material away from the hole and in between an inner surface of the tab plate and the outer surface of the turbine shell.
13 . The method as recited in claim 12 wherein the capillary actions causes the braze material to flow radially outward with respect to an axis of the hole.
14 . The method as recited in claim 10 further comprising arranging tabs of the tab plate circumferentially between elastic dampers.
15 . The method as recited in claim 14 wherein the elastic dampers are arc springs.
16 . The method as recited in claim 15 wherein the arc spring are supported by a spring retainer.
17 . The method as recited in claim 10 further comprising brazing the turbine shell and turbine blades together as the tab plate and the turbine shell are brazed together.
