Abstract

A hybrid module configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine includes a drive unit including an electric motor and a housing, a torque converter connected to the electric motor and at least one baffle blade extending axially from the housing radially outside of the electric motor and the torque converter.

First claim

What is claimed is:

1. A hybrid module configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine, the hybrid module comprising:
a drive unit including an electric motor and a housing;
a torque converter connected to the electric motor; and
at least one baffle blade extending axially from the housing radially outside of the electric motor and the torque converter.

2. The hybrid module as recited in claim 1 wherein the at least one baffle blade includes a first baffle blade and a second baffle blade, the first and second baffle blades being spaced circumferentially from each other.

3. The hybrid module as recited in claim 1 wherein the at least one baffle blade includes a base fixed to the housing and a blade portion extending axially from the base.

4. The hybrid module as recited in claim 3 wherein the blade portion includes a radially outer surface, a radially inner surface and at least one tab extending radially inward from the radially inner surface.

5. The hybrid module as recited in claim 4 wherein the at least one tab includes a first tab positioned on a transmission facing side of a portion of a rear cover of the torque converter.

6. The hybrid module as recited in claim 5 wherein the first tab contacts a radially extending wall of the rear cover.

7. The hybrid module as recited in claim 5 wherein the at least one tab includes a second tab positioned axially between a stator of the electric motor and a portion of a front cover of the torque converter.

8. The hybrid module as recited in claim 4 wherein the radially inner surface of the blade portion contacts an outer circumferential surface of the electric motor.

9. The hybrid module as recited in claim 4 wherein the radially inner surface of the blade portion contacts an outer circumferential surface of a cover of the torque converter.

10. The hybrid module as recited in claim 4 wherein the blade portion includes a circumferentially facing surface extending from the radially inner surface to the radially outer surface.

11. A method of constructing a hybrid module configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine, the method comprising:
providing a drive unit including an electric motor and a housing;
connecting a torque converter to the electric motor; and
fixing at least one baffle blade to the housing such that the at least one baffle blade extends axially from the housing radially outside of the electric motor and the torque converter.

12. The method as recited in claim 11 wherein the fixing of the at least one baffle blade to the housing includes fixing a first baffle blade and a second baffle blade to the housing, the first and second baffle blades being spaced circumferentially from each other.

13. The method as recited in claim 11 wherein the at least one baffle blade includes a base fixed to the housing and a blade portion extending axially from the base, the blade portion including a radially outer surface, a radially inner surface and at least one tab extending radially inward from the radially inner surface.

14. The method as recited in claim 13 wherein the at least one tab includes a first tab positioned on a transmission facing side of a portion of a rear cover of a cover of the torque converter.

15. The method as recited in claim 14 wherein the at least one tab includes a second tab positioned axially between a stator of the electric motor and a portion of a front cover of the cover of the torque converter.

16. The method as recited in claim 15 wherein the at least one baffle is fixed to the housing such that the first tab contacts a radially extending wall of the rear cover, the radially inner surface of the blade portion contacts an outer circumferential surface of the electric motor and the radially inner surface of the blade portion contacts an outer circumferential surface of the cover of the torque converter.

17. The method as recited in claim 13 wherein the blade portion includes a circumferentially facing surface extending from the radially inner surface to the radially outer surface.
