An assembly for transferring torque including a first component having first wall portions, a second component having second wall portions, wherein the first wall portions extend radially from the first component toward the second component, the second wall portions extend radially from the second component toward the first component, the first wall portions are axially aligned with the second wall portions, and a clearance is formed between the first and second wall portions, and a ring rivet having a connecting portion inserted into the clearance and deformed for creating at least one head for axially locking the first component and the second component together, and wherein deforming the connecting portion fills the clearance for rotationally locking the first component and second component together for enabling a transfer of torque between the first component and the second component.
1. An assembly for transferring torque comprising:
a first component having an inner diameter including a plurality of first wall portions forming respective sides for a plurality of first notches;
a second component having an outer diameter including a plurality of second wall portions forming respective sides for a plurality of second notches, wherein said plurality of first wall portions extends radially from said first component toward said second component, said plurality of second wall portions extends radially from said second component toward said first component, and the plurality of first wall portions is further, in a radial direction orthogonal to an axis of rotation for the assembly, from the axis of rotation for the assembly than the plurality of second wall portions; and,
a ring rivet having a connecting portion inserted into the pluralities of first and second notches and deformed for creating at least one head on at least one axial side of said assembly for axially locking said first component and said second component together for creating a positive fit between said connecting portion and each of said first and second components for rotationally locking said first component and second component together for enabling a transfer of torque between said first component and said second component.
2. The assembly recited in claim 1 , wherein said first component comprises a radially extending plate and said second component comprises a radially extending, annular projection wherein said annular projection is axially aligned with said radially extending plate and includes said plurality of second wall portions.
3. The assembly recited in claim 1 , wherein said connecting portion of said ring rivet comprises a plurality of tabs extending axially from a ring body.
4. The assembly recited in claim 3 , wherein:
the pluralities of first and second notches include respective pairs of radially aligned first and second notches;
said tabs each have a first shape;
each respective pair of radially aligned first and second notches forms a second shape; and
said first and second shapes are each selected from the group consisting of a rectangular shape, an arced shape, and a herringbone shape.
5. The assembly recited in claim 4 , wherein said first shape is said arced shape and said second shape is said rectangular shape.
6. An assembly for transferring torque in a torque converter comprising:
a damper flange having an inner diameter including a plurality of first wall portions forming respective sides for a plurality of first notches;
a hub having an outer diameter including a plurality of second wall portions forming respective sides for a plurality of second notches, wherein said plurality of first wall portions extends radially from said damper flange toward said hub, said plurality of second wall portions extends radially from said hub toward said damper flange, and the plurality of first wall portions is further, in a radial direction orthogonal to an axis of rotation for the assembly, from the axis of rotation for the assembly than the plurality of second wall portions; and,
a ring rivet having a connecting portion inserted into the pluralities of first and second notches and in contact with every first and second wall portion and deformed for creating at least one head on at least one axial side of said assembly for axially locking said damper flange and said hub together for creating a positive fit between said connecting portion and each of said damper flange and said hub for rotationally locking said damper flange and hub together for enabling a transfer of torque between said damper flange and said hub.
7. The assembly recited in claim 6 , wherein said damper flange comprises a radially extending plate and said hub comprises a radially extending, annular projection wherein said annular projection is axially aligned with said radially extending plate and includes said plurality of second wall portions.
8. The assembly recited in claim 6 , wherein said connecting portion of said ring rivet comprises a plurality of tabs extending axially from a ring body.
9. The assembly recited in claim 8 , wherein:
the pluralities of first and second notches include respective pairs of radially aligned first and second notches;
said tabs each have a first shape;
each respective pair of radially aligned first and second notches forms a second shape; and
said first and second shapes are each selected from the group consisting of a rectangular shape, an arced shape, and a herringbone shape.
10. The assembly recited in claim 9 , wherein said first shape is said arced shape and said second shape is said rectangular shape.
