A torque transmitting device for a drivetrain for transmitting a drive torque to an output element. The device having: an electric motor with a conversion unit, which comprises a stator and a rotor that is rotatable relative to the stator, for converting electrical energy into mechanical energy; and a torsional vibration damper with a damper mass received on a damper mass support such that the damper mass can be deflected to a limited extent against the action of a restoring force, the damper mass being arranged so as to overlap radially with the conversion unit.

Torque transmitting device

A hydrodynamic torque converter and a torsional vibration damper include a pump wheel connected on the drive side and a turbine wheel which is driven by the pump wheel. Between the housing of the torque converter and an output hub, a torsional vibration damper, which includes an input part that can be connected to the housing by a converter bridging clutch, and an output part, which is connected to the output hub, are provided. In order to allow a special wiring of the torsional vibration damper, an intermediate flange is arranged against a respective spring device, which acts in a circumferential direction, between the input part and the output part, said intermediate flange having a centrifugal pendulum and being connected to the turbine wheel.

Hydrodynamic torque converter and torsional vibration damper for same

A torsional vibration damper and a hydrodynamic torque converter comprising same is disclosed. The torsional vibration damper has an input part which can be rotated about a rotational axis (d) and an output part. An intermediate flange is arranged against a respective spring device, which acts in a circumferential direction, between the input part and the output part, and the intermediate flange is made of two axially spaced interconnected lateral parts, axially between which the input part and the output part are received. In order to improve the loading of the spring devices, the loading of the spring devices by means of the intermediate flange is at least partly provided by loading means arranged between the lateral parts.

Torsional vibration damper and hydrodynamic torque converter comprising same

A hydrodynamic torque converter and a torsional vibration damper for same, having a pump wheel connected on the drive side and a turbine wheel driven thereby, wherein a torsional vibration damper and an output part are provided between a housing of the hydrodynamic torque converter and an output hub. The torsional vibration damper having an input part that can be connected to the housing by a converter lock-up clutch, and said output part being connected to the output hub, wherein an intermediate flange arranged in each case counter to a spring device effective in the circumferential direction is provided between the input part and the output part. In order to protect the spring devices against damage in a manner not affecting the installation space, an angle of rotation of the intermediate flange counter to the effect of the spring devices is limited radially inside the spring devices.

The invention relates to a centrifugal force pendulum () for suppressing torsional oscillations in a drive train, comprising a first and a second flange () that are non-rotatably connected to the drive train and a first and a second pendulum mass () that are arranged axially offset between the flanges. The pendulum masses have different suppressing frequencies.
