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 present invention relates to a damping mechanism for damping rotational inhomogeneities in a power train of a motor vehicle, the damping mechanism comprising a slip for providing slip between an input region and an output region of a torque transfer mechanism Rotation 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 non-uniformity of rotation, wherein the adjustment device is designed to start from the average rotational speed, depending on The slip is regulated by at least one characteristic variable of the periodic vibration component of the variable component of the rotational speed, and a sensor device connected to the regulation device is arranged, wherein the sensor device is designed for slipping in the torque transmission path. The average rotational speed is determined after the slip mechanism, and the sensor arrangement is designed to determine the frequency of the variation component in the torque transmission path before the slip mechanism.

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...
