Abstract
A device for transmitting torque between an input side and an output side includes a hydrodynamic converter having a pump wheel that is connected to the input side and a turbine wheel that is coupled with the pump wheel hydrodynamically by a fluid, as well as a spring damper for coupling the turbine wheel with the output side and a centrifugal pendulum that is joined with one of the other elements in a torque-locked connection. In this case, only one spring damper is disposed in the flow of torque between the input side and the output side.
Claims9
A device for transmission of torque between an input side and an output side, the device comprising:
- a hydrodynamic converter having a pump wheel connected to the input side and a turbine wheel coupled hydrodynamically with the pump wheel via a fluid,
- a spring damper for coupling the turbine wheel with the output side,
- a centrifugal pendulum connected to the spring damper and including a pendulum mass movably attached to a pendulum flange,
- the spring damper being a sole spring damper positioned in a flow of torque between the input side and the output side,
- a first intermediate flange and a second intermediate flange configured for bracing the spring damper, wherein the first intermediate flange is arranged on a first axial side of the pendulum flange and the second intermediate flange is arranged on a second axial side of the pendulum flange, and
- a controllable friction clutch is connected to a radial outer side of the turbine wheel and configured for rigidly coupling the pump wheel with the turbine wheel.
