Abstract

A hybrid module shipping assembly includes a hybrid module configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine. The hybrid module includes a hybrid drive unit, a housing fixed to a front side of the hybrid drive unit and a torque converter fixed to a rear side of the hybrid drive unit. The torque converter includes an impeller hub. The hybrid module shipping assembly also includes a cap assembly inserted in the impeller hub and a shipping dome fixed to the housing such that the housing and shipping dome encase the hybrid drive unit, the torque converter and the cap assembly.

First claim

What is claimed is:

1. A hybrid module shipping assembly comprising:
a hybrid module configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine, the hybrid module including a hybrid drive unit, a housing fixed to a front side of the hybrid drive unit and a torque converter fixed to a rear side of the hybrid drive unit, the torque converter including an impeller hub;
a cap assembly inserted in the impeller hub; and
a shipping dome fixed to the housing such that the housing and shipping dome encase the hybrid drive unit, the torque converter and the cap assembly.

2. The hybrid module shipping assembly as recited in claim 1 further comprising an input shaft configured for connecting to the internal combustion engine, the input shaft protruding axially through the housing.

3. The hybrid module shipping assembly as recited in claim 2 wherein the hybrid module includes an electric motor and a clutch, the clutch configured for selectively connecting the torque converter to the input shaft or disconnecting the torque converter from the input shaft.

4. The hybrid module shipping assembly as recited in claim 1 wherein the cap assembly includes a plug inserted in the impeller hub, the plug including an axially extending portion contacting an inner circumferential surface of the impeller hub.

5. The hybrid module shipping assembly as recited in claim 4 wherein the cap assembly includes a seal axially sandwiched between a rim of the impeller hub and the shipping dome.

6. The hybrid module shipping assembly as recited in claim 5 wherein the rim includes an inner inclined edge forcing the seal axially against an axially facing radially extending surface of a radially extending portion of the plug and forcing the seal radially inward against an outer circumferential surface of a radially inner axially extending portion of the plug.

7. The hybrid module shipping assembly as recited in claim 5 wherein the shipping dome includes a protrusion at a center of a rear section thereof, the protrusion extending into the plug.

8. The hybrid module shipping assembly as recited in claim 7 wherein the plug includes a radially inner axially extending portion radially inside of the axially extending portion of the plug, the radially inner axially extending portion contacting an outer circumferential surface of the protrusion.

9. The hybrid module shipping assembly as recited in claim 8 wherein the plug includes a radially extending dome abutting portion extending from the radially inner axially extending portion along an inner axially facing radially extending surface of the shipping dome.

10. The hybrid module shipping assembly as recited in claim 1 wherein the cap assembly is fixed to the shipping dome.

11. The hybrid module shipping assembly as recited in claim 10 wherein the cap assembly is fixed to the shipping dome by an inner diameter of an axially extending portion of the cap assembly engaging an outer diameter surface of a protrusion at a center of a rear section of the shipping dome.

12. The hybrid module shipping assembly as recited in claim 10 wherein the cap assembly is fixed to the shipping dome by radially outwardly extending tabs of the cap assembly engaging an inwardly protruding segment of a rear section of the shipping dome.
