- the first torque Mg1 and the second torque Mg2 is brought together again at the planet 46.
- a vibration component in the first torque Mg1 which is passed through the first torque transmission path 47 through the phase shifter assembly 43, by the phase shift ideally 180 degrees to the vibration component in the second torque Mg2, which is not passed through the phase shifter 43, phase-shifted.

- the use of the planetary gear 46 with two different, partially axially overlapping toothed segments 81 g and 81 h is possible because a rotation angle of the planetary gear 46 is sufficiently low. Characterized in that the toothed segment 81 h, which meshes with the Antriebssonnenrad 12, is greater than the toothed segment 81 g, which meshes with the Antriebshohlrad 13, the amount of stationary translation increases compared to a transmission with known planetary gears with the same outer dimensions.
- the two toothed segments 81 g and 81 h of the planetary gear 46 may also be partially offset axially relative to one another as shown.
- the total torque Mo is passed through the converter housing 95 and a connecting plate 67 and further to a pump 74.
- the impeller 74 rotationally fixed, preferably by means of a welded ßfact, connected to the connecting plate 67.
- the connecting plate 67 is in turn rotationally fixed, preferably by means of a welded ßtagen, connected to the converter housing 95.
- the torque converter 90 thus applies the total torque Mo to the impeller 74.
- a torque Mt is applied to the turbine wheel 75.
- the two torque components Mt1 and Mt2 are reconnected to the planetary gear 46 again.
- the converged torque Mt, the output flange 36, the rotationally fixed preferably by means of a welded ßthetic connected to the planet 8, forwarded.
- the output flange 36 and the planet carrier 8 are designed as one component. From the output flange 36, the merged torque Mt to a transmission, not shown here or a similar component, are passed.
