Abstract
A torque converter turbine core ring is provided. The turbine core ring includes a plurality of arc sections having an inner circumference and an outer circumference and a plurality of weakened sections connecting the arc sections to each other. The weakened sections each having a lesser strength than each of the arc sections. A torque converter turbine, a torque converter and a method of forming a torque converter turbine are also provided.
Claims16
A torque converter turbine comprising:
- a turbine core ring comprising:
- a plurality of arc sections having an inner circumference and an outer circumference;
- and
- a plurality of weakened sections connecting the arc sections to each other, the weakened sections each having a lesser strength than each of the arc sections;
- a plurality of turbine blades connected to the torque converter turbine core ring;
- and
- a turbine shell connected to the turbine blades opposite the turbine core ring,
- wherein the turbine blades are connected to the arc sections,
- wherein turbine blades are not connected to the weakened section.

A method of forming a torque converter turbine comprising:
- forming a core ring to include a plurality of arc sections and a plurality of weakened sections connecting the arc sections to each other, the weakened sections each having a lesser strength than each of the arc sections, the arc sections having an inner circumference and an outer circumference, the arc sections each including a plurality of tab slots formed therein configured for receiving tabs of turbine blades, the tab slots being entirely between the inner circumference and the outer circumference, the weakened sections being formed by notches or slots having a different configuration than the tab slots such that the core ring is formed as an integral one-piece ring with each of the arc sections being integral with two of the weakened sections;
- and
- connecting the turbine blades to the arc sections by inserting the tabs of the turbine blades into the tab slots.
A torque converter turbine core ring comprising:
- a plurality of arc sections having an inner circumference and an outer circumference;
- and
- a plurality of weakened sections connecting the arc sections to each other, the weakened sections each having a lesser strength than each of the arc sections,
- wherein each of the plurality of weakened sections are radially thinner than each of the arc sections such that an inner circumference of each of the weakened sections is radially outside of the inner circumference of each of the arc sections and an outer circumference of each of the weakened sections is radially inside of the outer circumference of each of the arc sections.
