Filed:

Dec 12, 2006

Appl. No.:

11/637639

Inventors:

Michael G. Swank - Shreve OH, US
Patrick Lindemann - Wooster OH, US

Assignee:

Schaeffler Technologies GmbH & Co. KG - Herzogenaurach

International Classification:

B60W 10/02

US Classification:

477180

Abstract:

The present invention broadly comprises a method for controlling engine speed, engine torque, and torque converter output including the steps of applying engine torque to a torque converter and modulating the transferring of the torque to a pump for the torque converter. In some aspects, the torque converter further comprises a pump clutch and the method applies torque to the pump clutch and controllably slips the pump clutch. In some aspects, the method supplies engine torque from an engine with a turbocharger and controllably slips the pump clutch to increase speed and torque for the engine during a launch event for the vehicle or determines a parameter regarding operation of the vehicle and controllably slips the pump clutch responsive to the parameter. The present invention also comprises a method for controlling torque converter output by connecting a clutch between an engine and a torque converter and controllably slipping the clutch.

Appl. No.:

12/291212

Inventors:

Michael G. Swank - Shreve OH, US
Patrick Lindemann - Wooster OH, US

Assignee:

Schaeffler Technologies AG & Co. KG - Herzogenaurah

International Classification:

G06F 17/00

US Classification:

701 69, 701 82

Abstract:

A torque converter having a first damper stage, a second damper stage, a floating flange torsionally connecting the first and second damper stages, an inertia element, and a tuned torsion damper. The torsion damper connects the inertia element and the flange. In a preferred embodiment, the inertia element is a turbine. In one embodiment, the first damper stage is a radially outer damper stage and the second damper stage is a radially inner damper stage. In another embodiment, the torsion damper generates a friction torque when rotated.

Abstract:

A hybrid module housing includes a bulkhead. The bulkhead has a first radial channel for providing a clutch apply pressure, a second radial channel for providing a clutch cooling flow, and a third radial channel for providing a motor cooling flow. In an example embodiment, the third radial channel is arranged to be on a bottom half of the hybrid module housing when the hybrid module housing is installed in a vehicle. In an example embodiment, the first radial channel and the second radial channel are open at a radially outer surface of the bulkhead, and the third radial channel is sealed at the radially outer surface of the bulkhead. In an example embodiment, the third radial channel includes an axial passage open at a radial wall of the bulkhead.
