Abstract

A torque coupler includes an input side and an output side, which are situated rotatably around an axis of rotation, and in addition an intermediate plate for coupling with the input side, an output flange for coupling with the output side, a spring damper for coupling the intermediate plate with the output flange, and a centrifugal force pendulum having a pendulum flange and a pendulum mass. Here the pendulum flange extends between a first area, in which the pendulum flange is attached to the intermediate plate, and a second area, in which the pendulum mass is attached to the pendulum flange. The output flange has a cutout, through which a section of the pendulum flange which connects the two areas runs.

First claim

The invention claimed is:

1. A torsional vibration coupler comprising:
an input side and an output side, the input side and output side situated rotatably around an axis of rotation;
an intermediate plate for coupling with the input side;
an output flange for coupling with the output side;
a spring damper for coupling the intermediate plate with the output flange;
a centrifugal force pendulum having a pendulum flange and a pendulum mass;
the pendulum flange extending between a first area and a second area, the pendulum flange in the first area being attached to the intermediate plate, the pendulum mass being attached to the pendulum flange in the second area,
the output flange having a cutout, a section of the pendulum flange connecting the first and second areas running through the cutout.

2. The torque coupler as recited in claim 1 wherein the pendulum flange is in immediate contact with the intermediate plate in an attachment area.

3. The torque coupler as recited in claim 1 wherein the cutout is dimensioned so that the section of the pendulum flange runs against a boundary of the cutout when a predetermined maximum torsional angle between the intermediate plate and the output flange is reached.

4. The torque coupler as recited in claim 1 wherein the intermediate plate includes two plate elements axially offset and connected to each other and lying on different axial sides of the output flange.

5. The torque coupler as recited in claim 1 wherein the cutout extends in a radially running section of the output flange.

6. The torque coupler as recited in claim 1 wherein the pendulum flange is cranked and the cranked area runs through the cutout.

7. The torque coupler as recited in claim 1 wherein an axial part of the pendulum flange in the first area lies inside the cutout.

8. The torque coupler as recited in claim 1 further comprising another spring damper for coupling the input side with the intermediate plate, the spring damper and the further spring damper radially offset and concentrically arranged.

9. The torque coupler as recited in claim 1 further comprising a turbine, the turbine and the pendulum flange being attached to the intermediate plate by a common connecting element.
