Between the absorber masses 24, 25 and the carrier part 21 are effective in the circumferential direction and distributed over the circumference, the helical compression springs 26, which are each acted on the end face of the carrier part 21 and the absorber masses 24, 25.
- the Tilgermas sen 24, 25 are connected to one another radially outside of the carrier part 21, the absorber masses 24 axially folded radially outward and welded to the absorber masses 25, for example. It goes without saying that the angeord Neten absorber masses 24, 25 distributed over the circumference can be connected to one another in the circumferential direction and can thus form an annular absorber mass.
- the separating clutch 6 and the torsional vibration damper 19 are arranged in the dry space 27 of the bell housing 28 of the transmission, not shown in detail.
- the drying space 27 is limited in the gear direction by means of the axially fixed partition 29.
- the partition 29 is attached to the shoulder 30 of the bell housing 28, for example screwed or pinned. Radially on the inside, the partition 29 receives the central hub 32 axially fixed and rotatable by means of the bearing 31.
- the central hub 32 and the coupling hub 13 are rotatably connected to one another. Furthermore, with the central hub 32 on the separating clutch 6 and the torsional vibration damper 19 opposite lying side of the partition wall 29 of the rotor 33 of the electric machine 5 and the converter housing 34 of the hydrodynamic torque converter 35 are rotated and recorded centered. In this way, the transmission input shaft 36 of the transmission is relieved and the bearing on the bell housing 28, on which the stator 37 of the electric machine 5 is received and centered, is formed.
- the converter bridging clutch 40 is arranged radially within the electric machine 5 and within the converter housing 34 between the converter housing 34 and the output hub 41 of the torque converter 35.
- the torsional vibration damper 42 is effectively arranged and thus effective as a so-called lock updater and as a turbine damper.
- the output hub 41 is non-rotatably connected to the transmission input shaft 36.
- FIG. 2 shows the upper part of the hybrid drive train 1a, which is arranged around the axis of rotation d and is similar to the hybrid drive train 1 of FIG. 1, in section.
- the hybrid drive train 1 a has the rotationally adaptive torsional vibration damper 19 a, which is configured here as a centrifugal pen del 20 a.
- the centrifugal pendulum 20a is firmly connected by means of its carrier part 21a, for example, to the driven plate 22a of the driven part 14a of the separating clutch 6a by means of the rivet studs 23a.
- the centrifugal pendulum force pendulum 20a contains damper masses 24a, 25a which are arranged on both sides of the carrier flange 21a and are designed as pendulum masses 43a, 44a.
- the pendulum masses 43a, 44a are suspended in the centrifugal force field of the support part 21a rotating about the axis of rotation d depending on pendulum bearings 45a formed between the support part 21a and the pendulum masses 43a, 44a along a given swing path opposite the support part 21a.
- the self-aligning bearings 45a are each formed from two axially opposite, mutually connected pendulum masses 43a, 44a and the carrier part 21a, in each of which recesses with raceways are machined, on which a pendulum roller 46a crosses the raceways rolls.
