摘要： A method for transmission of and damping of a mean torque with a superposed alternating torque in a torque transmission arrangement for a powertrain of a motor vehicle having an input and an output. The mean torque with the superposed alternating torque is transmitted along a torque path from the input the output. The input rotates at an input speed and the output rotates at an output speed. A slip arrangement is provided in the torque path between the input and the output for generating a speed slip. The slip arrangement provides a maximum of an external activation of the speed slip in the area of a maxima of at least one periodic oscillation component of an alternating component and provides a minimum of an external activation of the speed slip in the area of a minima of at least one periodic oscillation component of the alternating component (new).

摘要： A torsional vibration damping arrangement, in particular mass damper subassembly, having a carrier which can be driven in rotation and a damper mass rotatably deflectable with respect to the carrier against the restoring action of a substantially radially extending damper spring. The damper spring is fixedly clamped in the damper mass and is supported or supportable with respect to the carrier for transmitting circumferential force. The damper spring is clamped between clamping elements arranged at both sides of the damper spring in circumferential direction.

摘要： A hybrid module (2) with a vibration reducing system (4) which is coupled between an output side (8) and an input side (6) of the hybrid module (2). The vibration reducing system (4) is configured to reduce an injected torsional irregularity, wherein the vibration reducing system (4) has a preload that is greater than an assembly-related preload. The hybrid module (2) also includes an electric machine (10) which is coupled to the input side (6) or to the output side (8) of the hybrid module (2). The electric machine (10) is configured to introduce a torque at the input side (6) or at the output side (8) which is directed against a rotational irregularity coming from a drive arrangement (5) in order to reduce the rotational irregularity.

摘要： A torsional vibration damping arrangement for a drivetrain of a vehicle, having a carrier arrangement which is rotatable around an axis of rotation, a deflection mass movable in circumferential direction relative to the carrier arrangement, carrier arrangement and the deflection mass are coupled to be rotatable relative to one another via restoring elements arranged in circumferential direction that extend from the deflection mass in direction of the carrier arrangement. A restoring element is deformable around a force application point which is movable in radial direction under centrifugal force and which is associated with the restoring element. The movable force application point is acted upon by a preloading force acting radially in direction of the axis of rotation by a preloading spring. A main axis of the preloading spring and a main axis of the restoring element do not extend coaxially.

摘要： A drive system for a vehicle comprises an internal combustion engine switchable between operating modes of different performance capability, and a torsional vibration damping arrangement that comprises a primary side preferably coupled to a crankshaft and a secondary side rotatable with respect to the primary side against the action of a damper element arrangement. The damper element arrangement has a stiffness which increases as the load torque to be transmitted increases, and the primary side and the secondary side are in a limiting relative rotational position with respect to one another during transmission of a maximum torque which can be delivered in an operating mode with lower performance capability at a maximum torque rotational speed, and the damper element arrangement provides a limiting stiffness in the limiting relative rotational position such that a natural frequency of the torsional vibration damping arrangement is below the maximum torque speed.

摘要： A method for the transmission and damping of a mean torque with a superposed alternating torque having an input and an output. The mean and superposed alternating torque is transmitted along a torque path from the input to the output area. An input speed is a mean speed and a superposed alternating component. A slip arrangement is provided in the torque path between the input and the output for transmitting the mean and superposed alternating torque and generating a speed slip between an input speed and an output speed. The slip arrangement provides a maximum of an external activation of the speed slip in a area of the maxima of at least one periodic oscillation component of the alternating component and provides a minimum of an external activation of the speed slip in an area of the minima of at least one periodic oscillation component of the alternating component.

摘要： A torsional vibration damping arrangement particularly for the drivetrain of a vehicle, having a carrier arrangement which is rotatable around an axis of rotation, a deflection mass which is movable in circumferential direction relative to the carrier arrangement. The carrier arrangement and the deflection mass are coupled so as to be rotatable relative to one another via a plurality of radially extending, flexible restoring elements which are arranged in circumferential direction. A restoring element is deformable in each instance around a force application point which is movable in radial direction under centrifugal force and which is associated with the restoring element. A first restoring element is preloaded in a first direction in inactive position of the torsional vibration damping arrangement, and in that a second restoring element is preloaded in a second direction opposite to the first direction in the inactive position.
