Detailed Description
Fig. 1 shows a half-sectional view of a torsional vibration damping arrangement 10 according to a further embodiment of the invention, and fig. 2 correspondingly shows a functional diagram of this embodiment. The torsional vibration damping arrangement 10 may be installed in a torque converter 12. The torsional vibration damper arrangement 10 comprises a first damper mechanism 14 having a first damper mass 16 and a first damper mass carrier 18, wherein the first damper mechanism 14 is designed according to a predetermined first damping frequency. A further second damping mechanism 24 is provided, which has a second damper mass 26 and a second damper mass carrier 28 and which is designed according to a second damping frequency.
The first damper mass 16 is coupled to the first damper mass carrier 18 via a first spring element 20. The second damper mass 26 is coupled to the second damper mass carrier 28 via a second spring element 30. The first and second damper mass carriers 18, 28 can in particular form a structural unit or be fixedly connected to one another.
The first damper mass carrier 18 is in particular designed as a damper input 34 of the torsional vibration damper 32, which is torsionally movable to a limited extent relative to a damper output 36 by the action of a spring element 38. The torsional damper 32 is operatively connected downstream of a torque converter lock-up clutch 40.
The turbine 42 of the torque converter 12 is attached to the damper output 36.
The second damper mechanism 24 is coupled to the second damper mass carrier 28 via a second spring element 30. In this case, the second spring element 30, which has a spring element acting on the circumferential side, can be bridged by a switching mechanism 44, which, when the switching mechanism 44 is activated, forms a rigid coupling of the second damper mass 26 to the second damper mass carrier 28.
Fig. 3 shows a half-sectional view of a torsional vibration damping arrangement 10 according to a further embodiment of the invention, and fig. 4 correspondingly shows a functional diagram of this embodiment. The basic structure of the torsional vibration damper arrangement 10 is similar to that of fig. 1, with the difference that the first and second damper mass carriers 18, 28 are mounted on the damper input 34 of the torsional vibration damper 32.
