Abstract

A converter unit having a damping system and having a torque transfer unit for connecting an input shaft separably to an output shaft, wherein the torque transfer unit has a co-rotating housing and the damping system can be installed centered and detachably on the housing is provided. With the converter unit proposed here standard components can be used, which are compact and easily installable.

First claim

What is claimed is:

1. A converter unit comprising:
a damping system; and
a co-rotating torque transfer unit housing, the damping system installable centered and detachably on the torque transfer unit housing; the damping system including a centrifugal force pendulum; and
an adapter device including a radially extending section positioned axially between a front axially facing surface of the torque transfer unit housing and masses of the centrifugal force pendulum, the adapter device being configured for transmitting torque from the damping system to the torque transfer unit housing, the adapter device being fastened to the torque transfer unit housing at the radially extending section by first fasteners.

2. The converter unit as recited in claim 1 wherein the damping system has a first flywheel and a second flywheel, the first and second flywheels spring-connected to each other via a spring system, the damping system connectible to the torque transfer unit housing through the first flywheel.

3. The converter unit as recited in claim 1 wherein the damping system is connected to the torque transfer unit housing by the adapter device.

4. The converter unit as recited in claim 3 wherein the damping system includes a ball bearing, the centrifugal force pendulum and adapter device axially connecting the torque transfer unit housing to the ball bearing.

5. The converter unit as recited in claim 1 wherein the torque transfer unit and the damping system, together in an assembled state, are connectable to an output shaft of an internal combustion engine.

6. A drive system to generate propulsion, comprising:
the converter unit as recited in claim 1 ; and
a drive unit, the drive unit has an output shaft, the damping system connectible to the output shaft.

7. A motor vehicle comprising:
the drive system as recited in claim 6 ; and
a drivetrain, the converter unit connecting the output shaft to the drivetrain.

8. The converter unit as recited in claim 1 wherein the torque transfer unit housing is a torque converter housing.

9. The converter unit as recited in claim 1 wherein the torque transfer unit housing includes a centering pin protruding axially into the damping system, the damping system being centered with the torque transfer unit housing via the centering pin.

10. The converter unit as recited in claim 1 wherein the adapter device includes an outer section positioned radially outside of the centrifugal force pendulum.

11. The converter unit as recited in claim 1 wherein the first fasteners each include a receptacle on the torque transfer unit housing and a fastening screw inserted through the adapter device and into the receptacle.

12. The converter unit as recited in claim 1 wherein the adapter device is fastened to the centrifugal force pendulum by second fasteners, the first fasteners being radially outward with respect to the second fasteners.
