Abstract
A hybrid drive module including: a torque converter with a cover, an impeller and a turbine; a rotor for an electric motor; a hub non-rotatably connected to the rotor and the cover and including a circumferential surface and a plurality of protrusions extending radially outward from the circumferential surface; and an end plate disposed between the plurality of protrusions and the rotor and engaged with the end plate and the rotor. The plurality of protrusions is formed of a material forming the hub and restrains the end plate and the rotor, with respect to the hub, in an axial direction.
Claims20
A hybrid drive module, comprising:
- a torque converter including:
- a cover;
- an impeller;
- and,
- a turbine;
- a rotor for an electric motor;
- a hub non-rotatably connected to the rotor and the cover and including:
- a first circumferential surface;
- and,
- a first plurality of protrusions:
- extending radially outward from the first circumferential surface;
- and,
- formed of a material forming the hub;
- and,
- an end plate:
- disposed between the first plurality of protrusions and the rotor;
- and,
- engaged with the first plurality of protrusions and the rotor, wherein the first plurality of protrusions restrains the end plate and the rotor, with respect to the hub, in a first axial direction.
A hybrid drive module, comprising:
- a torque converter including:
- a cover;
- an impeller;
- and,
- a turbine;
- a rotor for an electric motor;
- an end plate;
- a spring located between the end plate and the rotor and urging the rotor in a first axial direction;
- and,
- a hub non-rotatably connected to the rotor and the cover and including:
- a first circumferential surface;
- and,
- a first plurality of protrusions:
- extending radially outward beyond the first circumferential surface;
- formed of the material forming the hub;
- and,
- restraining the rotor, with respect to the hub, in a second axial direction, opposite the first axial direction.
A method of securing components to a hub of a hybrid drive module including a torque converter and a disconnect clutch, comprising:
- non-rotatably connecting a rotor for an electric motor to a first circumferential surface of a hub;
- placing an end plate on the first circumferential surface;
- deforming, using a first punch, material forming the hub to form a first plurality of protrusions extending radially outward from the first circumferential surface;
- and,
- restraining, with the first plurality of protrusions, displacement of the end plate and the rotor, with respect to the hub, in a first axial direction.
