Description
Die Erfindung bezieht sich auf einen Drehschwingungsdämpfer bzw. eine schwingungsdämpfende und drehelastische Kupplung mit zwischen einem Innenteil und einem Außenteil eingesetzten Federelementen zur Drehmomentenübertragung und über Drosselstellen miteinander in Verbindung stehenden flüssigkeitsgefüllten Kammern zur Dämpfung, wobei den Kammern eine Flüssigkeitsversorgungseinrichtung mit einer Förderpumpe und in die Kammern mündende Flüssigkeitsleitungen zugeordnet und von den Kammern ausgehende Entlüftungskanäle vorgesehen sind.The The invention relates to a torsional vibration damper or a vibration-damping and torsionally flexible coupling with between an inner part and a outer part used spring elements for torque transmission and throttle points communicating fluid-filled chambers for damping, wherein the chambers a liquid supply device with a feed pump and opening into the chambers fluid lines assigned and provided by the chambers outgoing ventilation channels are provided.
Bei
diesen Dämpfern
bzw. Kupplungen (
Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und einen Dämpfer bzw. eine Kupplung der eingangs geschilderten Art zu schaffen, der bzw. die bei vergleichsweise geringem Bauaufwand bereits beim Start die vollständige Dämpfungswirkung gewährleistet.Of the Invention is therefore based on the object to these shortcomings eliminate and a damper or to provide a coupling of the type described, the or at a comparatively low construction cost already at the start the complete damping effect guaranteed.
Die Erfindung löst diese Aufgabe dadurch, daß die Entlüftungskanäle einen kleineren Querschnitt als die Drosselstellen besitzen und in eine Rücklaufkammer ausmünden, wobei sich die Entlüftungskanäle vom äußeren Umfangsbereich der Kammern entlang von Zwischenstücken zwischen den Federelementen radial einwärts zu der Rücklaufkammer erstrecken. Durch diese einfache Maßnahme können die Kammern im Maße des Eindringens der Dämpfungsflüssigkeit entlüftet werden, so daß ein vollständiges Befüllen dieser Kammern auch schon vor einem Start ohne Lufteinschlüsse sicherzustellen ist und dann beim Startvorgang bereits die ganze Dämpfungsfähigkeit zur Verfügung steht. Dabei ist lediglich darauf zu achten, daß die Lage der Mündungen der Flüssigkeitsleitungen einerseits und die der Öffnungen zu den Entlüftungskanälen anderseits so aufeinander abgestimmt sind, daß durch das Eindringen der zugeförderten Dämpfungsflüssigkeit die in den Kammern befindliche Luft aus den Kammern in die Entlüftungskanäle verdrängt wird und daß der Querschnitt der Entlüftungskanäle einen Durchtritt von Dämpfungsflüssigkeit weitgehend verhindert, also wesentlich kleiner ist als der der Drosselstellen.The Invention solves this task in that the Venting channels one have smaller cross section than the throttle bodies and in a return chamber open out, wherein the venting channels from the outer peripheral region the chambers along intermediate pieces between the spring elements radially inward to the return chamber extend. By this simple measure, the chambers in the extent of penetration the damping fluid vented so that a complete filling this Chambers even before a start without air pockets is to ensure and then the entire damping capacity is available during the starting process. It is only necessary to ensure that the location of the mouths the fluid lines on the one hand and those of the openings on the other hand to the venting channels are coordinated so that by the penetration of the stream feeder damping fluid the air in the chambers is displaced from the chambers into the venting channels and that the cross section the ventilation channels one Passage of damping fluid largely prevented, that is much smaller than that of the throttle points.
Üblicherweise sind die Federelemente der Dämpfer bzw. Kupplungen zwischen Zwischenstücken eingespannt, die auch zur Trennung der Kammern voneinander und zur Ausbildung der Drosselstellen dienen. Dabei ist die Flüssigkeitszufuhr über die Flüssigkeitsversorgungseinrichtung und durch radiale Bohrungen des Innenteils als Flüssigkeitsleitungen sichergestellt. Verlaufen nun die mit radialem Abstand von den Mündungen der Flüssigkeitsleitungen ausgehenden Entlüftungskanäle in der dem Außenteil zugehörenden, die Kammern stirnseitig abschließenden Flanschplatte, wo bei von den Zwischenstücken überdeckte Nuten der Flanschplatte die Entlüftungskanäle bilden, entstehen in einfacher und aufwandsarm herstellbarer Weise die erforderlichen Entlüftungskanäle, welche Kanäle vom äußeren Umfangsbereich der Kammern ausgehen und dann entlang der Zwischenstücke radial einwärts sich erstrecken. Vorteilhafterweise ist für zwei benachbarte Kammern ein Entlüftungskanal mit einem gemeinsamen radialen Abschnitt und zwei davon abzweigenden tangentialen Anschlußabschnitten vorgesehen.Usually are the spring elements of the damper or clutches between intermediate pieces clamped, which also to separate the chambers from each other and to form the throttle points serve. Here, the liquid supply over the Liquid supply device and by radial bores of the inner part as liquid lines ensured. Run now with the radial distance from the mouths the liquid lines outgoing Venting channels in the the outer part belonging, the chambers end face flange plate, where at covered by the intermediate pieces Grooves of the flange plate form the ventilation channels, arise in a simple and low-producible manner, the required Venting channels, which channels from the outer peripheral area go out of the chambers and then along the spacers radially inwards extend. Advantageously, for two adjacent chambers a vent channel with a common radial section and two branching off tangential connection sections intended.
