Abstract

A hybrid module includes a rotational axis and an electric motor. The electric motor has a stator assembly and a rotor assembly. The stator assembly includes a stator plate with a first radially extending tab with a first threaded hole for receiving a first fastener for fixing the stator assembly to a jig plate, a second radially extending tab with a first dowel hole for receiving a first dowel to locate the stator assembly in the jig plate, and a third radially extending tab with a second dowel hole for receiving a second dowel to locate the stator assembly in a transmission housing. The rotor assembly is disposed radially inside of the stator assembly and includes a torque converter with a pilot for locating the torque converter relative to the jig plate or relative to an engine crankshaft.

First claim

What is claimed is:

1. A hybrid module comprising:
a rotational axis; and
an electric motor comprising:
a stator assembly comprising a stator plate, the stator plate comprising:
a first radially extending tab with a first threaded hole for receiving a first fastener for fixing the stator assembly to a jig plate;
a second radially extending tab with a first dowel hole for receiving a first dowel to locate the stator assembly in the jig plate; and
a third radially extending tab with a second dowel hole for receiving a second dowel to locate the stator assembly in a transmission housing; and

a rotor assembly disposed radially inside of the stator assembly and comprising a torque converter with a pilot for locating the torque converter relative to the jig plate or relative to an engine crankshaft.

2. The hybrid module of claim 1 wherein two of the first radially extending tab, the second radially extending tab, or the third radially extending tab are integrated into a single radially extending tab.

3. The hybrid module of claim 1 wherein the stator plate further comprises a fourth radially extending tab with a first through hole for receiving a second fastener for fixing the stator plate to the jig plate or to the transmission housing.

4. The hybrid module of claim 3 wherein of the first radially extending tab, the second radially extending tab, the third radially extending tab or the fourth radially extending tab are integrated into a single radially extending tab.

5. The hybrid module of claim 3 wherein:
the second fastener is for fixing the stator plate to the jig plate; and
the stator plate further comprises a fifth radially extending tab with a second through hole for receiving a third fastener for fixing the stator plate to the transmission housing.

6. The hybrid module of claim 1 wherein the torque converter comprises a drive plate for fixing the torque converter to the jig plate or to the engine crankshaft.

7. The hybrid module of claim 6 wherein:
the drive plate comprises a stud; and
the torque converter is fixed to the jig plate or to the engine crankshaft by a nut threaded onto the stud.

8. The hybrid module of claim 1 further comprising:
the jig plate; and
the first fastener, wherein the jig plate comprises a first jig plate through hole and the first fastener is installed in the first jig plate through hole and threaded into the first threaded hole to fix the stator plate to the jig plate.

9. The hybrid module of claim 8 wherein the jig plate comprises a central bore aligned with the rotational axis and the pilot is installed in the central bore to locate the torque converter relative to the jig plate.

10. The hybrid module of claim 8 further comprising a lifting eye fixed to the jig plate by a lifting eye fastener aligned with the rotational axis.

11. A hybrid module comprising:
a rotational axis;
a jig plate comprising:
a first jig plate through hole;
a first jig plate dowel hole; and
a central bore aligned with the rotational axis; and

an electric motor comprising:
a stator assembly comprising a stator plate, the stator plate comprising:
a first radially extending tab with a first threaded hole; and
a second radially extending tab with a first dowel hole; and

a rotor assembly disposed radially inside of the stator assembly and comprising a torque converter with a pilot installed in the central bore locating the torque converter relative to the jig plate;

a first fastener:
extending through the first jig plate through hole;
threaded into the first threaded hole; and
fixing the stator assembly to the jig plate; and

a first dowel installed in the first dowel hole and in the first jig plate dowel hole locating the stator plate relative to the jig plate.

12. The hybrid module of claim 11 wherein the stator plate further comprises a third radially extending tab with a second dowel hole for receiving a second dowel to locate the stator assembly in a transmission housing.

13. The hybrid module of claim 11 further comprising a second fastener, wherein:
the jig plate further comprises a first jig plate threaded hole;
the stator plate further comprises a fourth radially extending tab with a first through hole; and
the second fastener:
extends through the first through hole;
is threaded into the first jig plate threaded hole; and
fixes the stator assembly to the jig plate.

14. The hybrid module of claim 13 wherein the stator plate comprises a fifth radially extending tab with a second through hole for receiving a third fastener for fixing the stator plate to a transmission housing.
