Abstract
A hybrid drive module with a torque converter and a rotor carrier. The torque converter includes a cover made of a piece of material, an impeller and a turbine. The rotor carrier is made of a piece of aluminum different from the piece of material, is arranged to non-rotatably connect to a rotor for an electric motor, and includes a connection element. The connection element: is formed from the piece of aluminum and includes at least one rivet non-rotatably connecting the cover and the rotor carrier; or is made of a piece of non-aluminum material, partially embedded in the piece of aluminum, and non-rotatably connected to the cover.

A hybrid drive module, comprising:
- a torque converter including:
- a cover formed of a first piece of material;
- an impeller;
- and,
- a turbine;
- and,
- a rotor carrier:
- made of a second piece of material different from the first piece of material;
- arranged to non-rotatably connect to a rotor for an electric motor;
- and,
- including a connection element:
- formed from the second piece of material and including at least one first rivet non-rotatably connecting the cover and the rotor carrier;
- or,
- made of a third piece of material partially embedded in the second piece of material and non-rotatably connected to the cover.
A method of assembling a hybrid drive module including a rotor carrier made of a first piece of material and including at least one rivet, comprising:
- inserting the at least one rivet through at least one respective opening in a cover for a torque converter, the cover made of a second piece of material different from the first piece of material;
- deforming the at least one rivet to fixedly secure the rotor to the cover;
- fixing an impeller for the torque converter to the cover;
- and,
- installing a turbine and stator for the torque converter.
