Abstract

A rotor assembly includes a torque converter including a housing forming a hydraulic chamber, a rotor for an electric motor, a rotor carrier non-rotatably connected to the rotor that is fixed to the torque converter housing, a rotor carrier flange, a spring, and a snap ring. In some embodiments, the rotor carrier includes a groove and a castellated portion, the snap ring is disposed in the groove, and the spring clamps the rotor carrier flange between the snap ring and the castellated portion.

First claim

What we claim is:

1. A rotor assembly, comprising:
a torque converter including a housing forming a hydraulic chamber;
a rotor for an electric motor;
a rotor carrier non-rotatably connected to the rotor, wherein the rotor carrier is fixed to the torque converter housing;
a rotor carrier flange;
a spring; and,
a snap ring, wherein:
the rotor carrier includes a groove and a castellated portion;
the snap ring is disposed in the groove; and,
the spring clamps the rotor carrier flange between the snap ring and the castellated portion.

2. The rotor assembly of claim 1 wherein the spring is a diaphragm spring.

3. The rotor assembly of claim 1 wherein the spring is disposed axially between the snap ring and the rotor carrier flange.

4. The rotor assembly of claim 1 , further comprising a retention element disposed between the spring and the snap ring.

5. The rotor assembly of claim 4 wherein:
the retention element is a shim having at least one tab; and,
the at least one tab is bent toward the snap ring such that the at least one tab contacts at least a portion of the snap ring to secure the snap ring in the groove.

6. The rotor assembly of claim 1 wherein the spring includes at least one retaining tab positioned under the snap ring to secure the snap ring in the groove.

7. The rotor assembly of claim 6 wherein the at least one retaining tab is integrally formed with the spring.

8. A rotor assembly, comprising:
a torque converter including a housing forming a hydraulic chamber;
a rotor for an electric motor;
a rotor carrier non-rotatably connected to the rotor, wherein the rotor carrier is fixed to the torque converter housing;
a rotor carrier flange including an inner diameter;
a spring; and,
a snap ring including a first end opposite a second end, wherein:
the rotor carrier includes a groove and a castellated portion;
the snap ring first end is disposed in the rotor carrier groove; and,
the spring urges the rotor carrier flange into contact with the rotor carrier.

9. The rotor assembly of claim 8 wherein the spring is disposed axially between the rotor carrier flange and the castellated portion.

10. The rotor assembly of claim 8 wherein:
the rotor carrier flange includes a groove formed in the inner diameter; and
the snap ring second end is disposed in the groove of the rotor carrier flange.

11. The rotor assembly of claim 10 wherein the rotor carrier groove is radially aligned with the rotor carrier flange groove.
