An internal combustion engine comprises includes a turbo-compound and the known Föttinger-coupling is replaced by a torsion vibration damper. The Föttinger-coupling, which is used to transmit power, has high losses in power when it is necessary to have a differential rotational speed between the input side and the output side, that is, the appearance of a slip. The losses are not used in a torsion vibration damper which has at least the same quality as a Föttinger-coupling.

What is claimed is: 1. A compound drive comprising in combination a combustion engine and at least one exhaust gas turbine in the exhaust gas stream and an absorber, the absorber located between said exhaust turbine and an input point, where the energy of the exhaust gas turbine in the flow of power from the combustion engine is fed into said input point, there being a speed reduction gear situated between the exhaust gas turbine and the input point, characterized in that a torsion vibration damper—having at least one input part and output part—is situated in the flow of force from the exhaust gas turbine to the input point;wherein said torsion vibration damper is equipped with extensively active energy storage devices;wherein said extensively active energy storage devices are in the form of coil springs;wherein said input part of said torsion vibration damper is radially outwardly positioned over the input point relative to the output part of said torsion vibration damper and,wherein the absorber tunes the damping behavior of the torsion vibration damper.
