A centrifugal pendulum having a pendulum flange, a first pendulum mass and a second pendulum mass and a spring arrangement, wherein the first pendulum mass and the second pendulum mass are positioned side-by-side in the circumferential direction, wherein the first pendulum mass is coupled with the pendulum flange by a first slotted guide and the second pendulum mass is coupled with the pendulum flange by a second slotted guide. The first slotted guide guides the first pendulum mass along a first oscillation path and the second slotted guide guides the second pendulum mass along a second oscillation path in an oscillating motion. The spring arrangement at least partially couples the first pendulum mass with the second pendulum mass, wherein at least one of the two pendulum masses has a receptacle. The spring arrangement includes a spring element and a protective device, wherein the protective device is positioned at least partially in the receptacle of the pendulum mass.

Centrifugal pendulum

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.

Device for transmitting torque

A turbine torsional vibration damper, in particular a simple torsional vibration damper, for a vehicle, preferably for a drivetrain of a motor vehicle, having a damper part for introducing a torque into the turbine torsional vibration damper and a damper part for extracting the torque from the torsional vibration damper, wherein a pendulum mass flange of a centrifugal pendulum device is rigidly coupled mechanically with a damper part of the turbine torsional vibration damper. A converter or a torque transmission device for a vehicle, in particular for a drivetrain of a motor vehicle, wherein the converter or torque transmission device has a turbine torsional vibration damper according to the invention.

Turbine torsional vibration damper, and converter and torque transmission device

A torque transfer device mountable rotatably around an axis of rotation to transfer a drive torque between an input side and an output side, having a converter wheel of a hydrodynamic converter and a centrifugal force pendulum, which has a pendulum flange extending in an at least partially radial direction and at least one pendulum mass, where the pendulum mass is positioned on a long side of the pendulum flange and is coupled with the pendulum flange by means of a sliding block guide. A first coupling device is designed to provide a connection for transferring torque between the pendulum flange and the converter wheel, where the first coupling device is connected to the pendulum flange at least partially radially to the outside of the pendulum mass to provide an exchange of torque between the converter wheel and the pendulum flange radially to the outside of the pendulum mass.

Torque transfer device

A torsional vibration damper comprises an input side and an output side which are arranged rotatably around an axis of rotation, an intermediate plate, and two elastic elements which are arranged on different circumferences around the axis of rotation, where the first elastic element is set up to transmit a power from the input side to the intermediate plate and the second elastic element is set up to transmit a power from the intermediate plate to the output side. Furthermore, the torsional vibration damper includes a single-piece retainer to support the first elastic element on a radially outer surface, while the retainer includes a contact element for engaging with one end of the first elastic element.

Torsional vibration damper

The vibration damper for damping vibrations for rotation around an axis of rotation, including a first component with at least one bow spring channel formed radially outside of a second component. A spring is formed in the bow spring channel, and fixed by a counter-component, wherein the first and second component and counter-component are made of sheet metal, characterized in that the second component and at least one of the following contact components: a) the first component and b) the counter-component have common contact areas, into which the second component and the at least one contact component run vertically to the rotation axis, and in which the edges thereof for centering lie one against the other, at least in some sections.

A torque coupler includes an input side and an output side, which are situated rotatably around an axis of rotation, and in addition an intermediate plate for coupling with the input side, an output flange for coupling with the output side, a spring damper for coupling the intermediate plate with the output flange, and a centrifugal force pendulum having a pendulum flange and a pendulum mass. Here the pendulum flange extends between a first area, in which the pendulum flange is attached to the intermediate plate, and a second area, in which the pendulum mass is attached to the pendulum flange. The output flange has a cutout, through which a section of the pendulum flange which connects the two areas runs.
