DREHSCHWINGUNGSDÄMPFUNG DURCH GEZIELTEN SCHLUPF INlDER REIBUNGSKUPPLUNGROTARY VIBRATION DAMPING THROUGH TARGETED SLIP INl THE FRICTION CLUTCH

BESCHREIBUNGDESCRIPTION

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Entkoppelung von Brennkraftmaschine und Antriebsstrang, insbesondere bei Kraftfahrzeugen mit Reibungskupplung, zur Dämpfung der Torsionssciiwingungen bzw. zur Unterdrückung von Geräuschen, die z. B. im Getriebe auftreten können,The invention relates to a method and a device for decoupling the internal combustion engine and the drive train, in particular in motor vehicles with friction clutches, to dampen torsional vibrations or to suppress noise, the z. B. can occur in the transmission,

Es ist bisher allgemein üblich, in den Antriebsstrang eines Kraftfahrzeuges mit Brennkraftmaschine einen Torsionsschwingungsdämpfer einzufügen, der die von der Brennkraftmaschine hervorgerufenen Torsionsschwingungen soweit abbaut, daß die nachfolgenden Aggregate wie beispielsweise das Getriebe von diesen Schwingungen verschont bleiben bzw, die als lästig empfundenen Geräusche dadurch unterdrückt werden. In den allermeisten Fällen sind diese Torsionsschwingungsdämpfer in die Kupplungsscheiben integriert. Als eines von vielen bekannten Beispielen sei auf die DE-PS 1 680 049 hingewiesen. Bei dieser Patentschrift geht beispielsweise der Aufwand soweit, daß für den Leerlaufbereich und für den Lastbereich jeweils ein gesonderter Schwingungsdämpfer vorgesehen ist. Selbst bei diesem großen Aufwand ist es nicht immer möglieh, die auftretenden Torsionsschwingungen auf das gewünschte Maß zu reduzieren. In zunehmendem Maße werden nämlich, die einzelnen Aggregate der Brennkraftmaschinen in Kraftfahrzeugen leichter ausgebildet, wodurch, sich die Torsionsschwingungen verstärkt aus~ wirken.It has hitherto been common practice to include a torsional vibration damper in the drive train of a motor vehicle with an internal combustion engine insert that reduces the torsional vibrations caused by the internal combustion engine to such an extent that the following Units such as the gearbox are spared these vibrations or the noises that are perceived as annoying as a result be suppressed. In the vast majority of cases, these torsional vibration dampers are integrated into the clutch disks. DE-PS 1,680,049 is referred to as one of many known examples. In this patent, for example the effort so far that for the idle area and for the A separate vibration damper is provided for each load area. Even with this great effort it is not always possible to reduce the occurring torsional vibrations to the desired level. Increasingly, namely, the individual Units of the internal combustion engines in motor vehicles are lighter, which means that the torsional vibrations are amplified from ~ works.

Es ist nun Aufgabe der vorliegenden Erfindung, eine besonders wirksame Unterdrückung von Torsionsschwingungen z-u erzielen, die mit möglichst wenig mechanischem Aufwand und möglichst auch raumsparend zu erstellen ist.It is now the object of the present invention to achieve a particularly effective suppression of torsional vibrations z-u, the is to be created with as little mechanical effort as possible and as space-saving as possible.

Diese Aufgabe wird erfindungsgemäß durch das Kennzeichen des Hauptanspruches gelöst. Die Aufrechterhaltung eines geringen Schlupfes in der Reibungskupplung, die ansonsten.als Anfahr- und Schaltkupplung dient, dampft die Torsionsschwingungen in sehr wirkungsvoller Weise, Dabei hat sich bei Versuchen herausgestellt, daß ein geringer Schlupf auch bei den bereits in Betrieb befindlichen Reibungskupplungen hinsichtlich der Wärmeentwicklung ohne negative Auswirkungen bleibt.According to the invention, this object is achieved by the characteristic of Main claim solved. Maintaining a low level of slippage in the friction clutch, which is otherwise Clutch is used, dampens the torsional vibrations in a very effective way, it has been found in tests, that there is little slip even in the friction clutches that are already in operation with regard to the generation of heat remains without negative effects.

Es ist dabei ausreichend, wenn der Schlupf in einer Größenordnung von weniger als 100 U/min liegt. Vorzugsweise kann mit einem Schlupf von 25,,Λ50 U/min gearbeitet werden.It is sufficient if the slip is in the order of magnitude of less than 100 rpm. Preferably, with a slip of 25 ,, Λ 50 U / min to work.

Zur Durchführung des Verfahrens wird vorgeschlagen, daß eine Kupplungsbetätigungsvorrichtung vorhanden ist, die in Abhängigkeit vom festgestellten Schlupf die Anpreßkraft der Reibungskupplung nachregelt. Zu diesem Zwecke wird eine überwachungsvorrichtung vorgesehen, die die Ein- und Ausgangsdrehzahl der Reibungskupplung mißt, eine Vergleichseinrichtung zum Vergleich dieser beiden Drehzahlen, wodurch mit Hilfe dieser Daten die Kupplungssteuerung die Anpreßkraft regulieren kann. Eine solche automatische Steuerung ist besonders dann von Vorteil, wenn die Reibungskupplung bereits durch eine automatische Kupplungsbetätigung gesteuert wird. Hierbei sind die Drehzahlgeber notwendigerweise bereits vorhanden \ind es ist lediglich in der Steuerelektronik eine entsprechende Regelmöglichkeit vorgesehen, die zum Nachregulieren des maximalen Schlupfes dient. Dabei können beispielsweise noch andere Daten überwacht und .in die Elektronik eingegeben werden,-z, B, die Unterdrückung des Schlupfes außerhalb des Drehzahlbereiches, in welchem die ungewünschten Geräusche auftreten können,To carry out the method it is proposed that a Clutch actuating device is present, which, depending on the detected slip, the contact pressure of the friction clutch readjusts. For this purpose, a monitoring device is provided that the input and output speed of the friction clutch measures, a comparison device for comparing these two speeds, whereby the clutch control with the help of this data can regulate the contact pressure. Such an automatic control is particularly advantageous when the friction clutch is already controlled by an automatic clutch actuation. Here the speed sensors are necessary already present \ ind it is only in the control electronics a corresponding control option is provided, which is used to readjust the maximum slip. For example other data is monitored and entered into the electronics be, -z, B, the suppression of the slip outside the Speed range in which the undesired noises can occur,

Die Art der Kupplungsfoetätigung ist hierbei zweitrangig, d, h., die Kupplungsbetätigung kann weiterhin elektrisch, mechanisch, hydraulisch oder pneumatisch erfolgen,The type of clutch actuation is of secondary importance, i.e. the clutch can still be operated electrically, mechanically, hydraulically or pneumatically,
