Problems solved by technology

[0009] A disadvantage of the known methods is that they are inflexible and therefore do not adequately provide for decoupling or attenuation of rotational inhomogeneities
Furthermore, these methods require heavy and thus more expensive components for the pre-decoupling to be performed for rotational inhomogeneities

Embodiment Construction

[0035] exist figure 1 A damping mechanism 1 for a drive train of a motor vehicle is shown in . In this case, the drive train includes an engine 10 which is connected torque-downstream to a rotational inhomogeneity pre-decoupler 9 . The rotational inhomogeneity pre-decoupler 9 is further connected torque downstream to a slip mechanism 2, wherein the slip mechanism 2 is connected on the output side to a transmission 11, and the transmission 11 is connected to further transmission elements (in figure 1 is referred to as the rest of the power train 12) connection. A crankshaft position sensor 20 is arranged between the engine 10 and the rotational irregularity pre-decoupler 9 . A rotational speed sensor 21 is arranged between the rotational unevenness pre-decoupler 9 and the slip mechanism 2 , and a further rotational speed sensor 22 is situated between the slip mechanism 2 and the transmission 11 . The rotational speed sensor 21 is therefore arranged in the input region 3 of t...

Abstract

The invention relates to a damping arrangement for dampening rotational irregularities in a drive train of a motor vehicle, comprising a slip arrangement for providing a slip between the input regionand output region of a torque transmission arrangement, wherein the slip arrangement comprises a control device, which is designed to control the slip as a function of a measurement signal for a rotational irregularity, wherein the control device is designed to control the slip as a function of at least one parameter of a periodic vibration component of an alternating component of a speed proceeding from an average speed, wherein a sensor device is arranged which is connected to the control device, wherein the sensor device is designed to determine the average speed in the torque transmissionpath after the slip arrangement and wherein the sensor device is designed to determine a frequency of the alternating component in the torque transmission path before the slip arrangement.

Description

technical field [0001] The present invention relates to a damping mechanism for damping rotational inhomogeneities in a drive train of a motor vehicle, said damping mechanism comprising a slip for providing slip between an input region and an output region of a torque transfer mechanism A slip mechanism, wherein the slip mechanism comprises an adjustment device, which is designed to adjust the slip as a function of the measurement signal for the rotational inhomogeneity. [0002] The invention also relates to a method for damping rotational inhomogeneities in a drive train of a motor vehicle, wherein slip is provided between an input region and an output region of a torque transmission mechanism by means of a slip mechanism, and In this case, the slippage is adjusted by means of the adjusting device as a function of the measurement signal for the rotational inhomogeneity. [0003] While it may be used in any motor vehicle, the invention is described with respect to a motor ve...
