Abstract

Official abstract text for this publication.

A torque transmission device comprising a torque converter disposed in a drive train of a motor vehicle, in particular a hydrodynamic torque converter or a fluid clutch, wherein the converter or the fluid clutch comprises a turbine shell and a pump shell which can be coupled through a pump clutch and at least one pump damper with a converter cover, and comprising at least one converter damper and at least one converter lock up clutch.

First claim

Opening claim text (preview).

What is claimed is: 1. A torque transmission device comprising a torque converter disposed in a drive train of a motor vehicle, wherein the torque converter comprises: a turbine shell; a pump shell; a pump clutch with an input and an output; at least one pump damper with an input directly connected to a converter cover and an output directly connected to the input of the pump clutch; at least one converter damper with: an output; and an input directly connected to the output of the pump clutch; and, at least one converter lock up clutch with an input directly connected to the output of the at least one converter damper, wherein when the pump clutch is closed and the at least one converter lock up clutch is open: a torque path passes through in sequence, the cover, the pump damper, the pump clutch, the pump shell and the turbine shell; and, the torque path does not pass through the at least one converter damper. 2. A torque transmission device according to claim 1 , wherein the pump clutch can be connected or is connected between the converter cover and the converter damper. 3. A torque transmission device according to claim 1 , wherein the converter damper is connected in front of the converter lock up clutch. 4. A torque transmission device according to claim 1 , wherein the converter damper can be connected or is connected in series with the pump damper. 5. A torque transmission device according to claim 1 , wherein the pump shell and the turbine shell can be connected or is connected in series with the pump damper and the pump clutch. 6. A torque transmission device according to claim 1 , wherein the pump shell and the turbine shell can be connected or is connected parallel to the converter damper and the converter lock up clutch. 7. A torque transmission device according to claim 1 , wherein the pump clutch and the converter lock up clutch can be connected or are connected in series. 8. A torque transmission device according to claim 1 , wherein the converter lock up clutch and the converter damper can be connected or is connected in series with the pump damper. 9. A torque transmission device according to claim 1 , wherein the converter damper can be connected or is connected between the pump damper and the converter lock up clutch. 10. A torque transmission device according to claim 1 , wherein the torque converter comprises a stator shell. 11. A torque transmission device according to claim 1 , wherein the pump shell and the turbine shell can be connected or is connected in series with the pump damper or the pump clutch. 12. A torque transmission device according to claim 1 , wherein the pump shell and the turbine shell can be connected or is connected parallel to the converter damper or the converter lock up clutch. 13. A torque transmission device according to claim 1 , wherein the converter lock up clutch or the converter damper can be connected or is connected in series with the pump damper.
