Abstract

A force transmission device including an input and an output, a hydrodynamic component, having at least one pump shell and one turbine shell, and a device for damping vibrations including a primary component and a secondary component, rotatable relative to each other in circumferential direction, wherein the secondary component is connected at least indirectly torque proof with the output, and the turbine shell is connected at least indirectly torque proof with the output. The connection between the turbine shell and the output, or an element coupled torque proof with the output, is performed through the intermediary element connected with the turbine shell in a first coupling section and coupled in a second coupling section with the output, or with the element coupled torque proof with the output, wherein the intermediary element is characterized by a substantially constant wall thickness, and the two coupling areas are disposed offset relative to each other in axial and in radial direction.

Claims (18)

1. A force transmission device comprising:

an input;

an output;

a hydrodynamic component having at least one pump shell and one turbine shell;

a damper for damping vibrations, the damper including a primary component and a secondary component rotatable relative to each other in a circumferential direction, the secondary component being non-rotatably connected to the output and the turbine shell being non-rotatably connected to the primary component with an intermediary element being disposed between the turbine shell and the primary component, wherein the turbine shell is connected to the primary component via the intermediary element so as to define a first coupling section for coupling with the turbine shell and a second coupling section for coupling with the primary component, the first and second coupling sections being disposed offset relative to each other in an axial and a radial direction, wherein the first coupling section is disposed at a larger diameter than the second coupling section in the radial direction.

2. The force transmission device as recited in claim 1 wherein the intermediary element has a substantially constant wall thickness between the first and second coupling sections.

3. The force transmission device as recited in claim 1 wherein the intermediary element is a formed sheet metal part.

4. The force transmission device as recited in claim 1 wherein the intermediary element is plastic or a fiber composite material.

5. The force transmission device as recited in claim 1 wherein the intermediary element has a S- or Z- shape cross sectional profile.

6. The force transmission device as recited in claim 1 wherein the intermediary element includes joining surfaces at the first and second coupling sections, the joining surfaces being flange surfaces disposed parallel to each other.

7. The force transmission device as recited in claim 1 wherein the intermediary element includes joining surfaces provided as flange surfaces at the first and second coupling sections, the flange surfaces being disposed at an angle relative to each other.

8. The force transmission device as recited in claim 1 wherein the intermediary element includes joining surfaces provided as flange surfaces at the first and second coupling sections, the flange surfaces being orthogonal to each other.

9. The force transmission device as recited in claim 1 wherein the first coupling section has a flange surface and a complementary flange surface is formed at the turbine shell through a circumferentially extending collar disposed in the inner radial section of the turbine shell.

10. The force transmission device as recited in claim 1 wherein the first coupling section has a flange surface and a complementary flange surface in the first coupling section is formed at the turbine shell by a partial surface at an outer circumference of the turbine shell.

11. The force transmission device as recited in claim 1 wherein at least one connection between the first and/or second coupling section and the turbine shell or the primary component coupled at least indirectly torque proof with the output is a continuous material connection.

12. The force transmission device as recited in claim 1 wherein at least one connection between the first and second coupling section and the turbine shell or the primary component coupled at least indirectly torque proof with the output is provided a friction locked connection.

13. The force transmission device as recited in claim 1 wherein at least one connection between the first and second coupling section and the turbine shell or the primary component coupled at least indirectly torque proof with the output is provided a form locked connection.

14. The force transmission device as recited in claim 1 further comprising a device-for circumventing a hydrodynamic power flow, having a friction assembly including a first and a second friction surface array operably engageable through an actuation device.
