Abstract
Description
Die vorliegende Erfindung betrifft eine von den Schwingungen einer Kurbelwelle entkoppelte Riemenscheibe mit integriertem Viskose-Drehschwingungsdämpfer, umfassend einen Schwungring, der in einem mit einem viskosen Medium gefüllten Dämpfergehäuse angeordnet und relativ zu diesem verdrehbar ist, sowie ein Lager und eine elastische Kupplung zur relativ verdrehbaren und in Umfangsrichtung der Riemenscheibe elastischen Abstützung der Riemenscheibe gegenüber dem Dämpfergehäuse, wobei die Riemenscheibe dem Schwungring axial benachbart zugeordnet und das Lager von einem Axialvorsprung des Dämpfergehäuses getragen ist.The The present invention relates to one of the vibrations of a crankshaft decoupled pulley with integrated viscous torsional vibration damper, comprising a flywheel, which is arranged in a filled with a viscous medium damper housing and rotatable relative to this, as well as a bearing and an elastic Coupling to the relatively rotatable and in the circumferential direction of the pulley elastic support the pulley opposite the damper housing, wherein the pulley assigned to the flywheel axially adjacent and the bearing is supported by an axial projection of the damper housing.
Schwingungsentkoppelte
Riemenscheiben mit integrierten Viskose-Drehschwingungsdämpfern der gattungsgemäßen Art
sind an sich bekannt, wie zum Beispiel aus der
Bei den bekannten Konstruktionen dieser Art besteht die elastische Kupplung aus einem in sich geschlossenen Ring aus Gummi oder einem gummiartigen Material, welches konstruktionsbedingt in erster Linie Zugbeanspruchungen ausgesetzt ist. Diese systembedingte ständige Zugbeanspruchung führt zu einer relativ beschränkten Lebensdauer der Kupplung.at The known constructions of this type is the elastic coupling from a self-contained ring of rubber or a rubbery Material, which by design primarily tensile stresses is exposed. This systemic continuous tensile stress leads to a relatively limited Service life of the clutch.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine schwingungsentkoppelte Riemenscheibe mit integriertem Viskose-Drehschwingungsdämpfer der gattungsgemäßen Art zu schaffen, welche sich durch eine relativ lange Lebensdauer auszeichnet.Of the present invention is based on the object, a vibration decoupled Pulley with integrated viscose torsional vibration damper generic type to create, which is characterized by a relatively long life.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Axialvorsprung an seinem dem Dämpfergehäuse abgewandt liegenden Ende einen radial nach außen gerichteten Flansch und einen sich daran anschließenden, sich in Richtung des Dämpfergehäuses erstreckenden Ringabschnitt aufweist, welcher in einen zur Flanschseite des Axialvorsprunges hin offenen Ringraum der Riemenscheibe hineinragt, so dass zwischen dem Ringabschnitt einerseits und einem auf dem Lager radial abgestützten Ringstutzen der Riemenscheibe andererseits eine Kammer zur Aufnahme der Kupplung gebildet und diese Kammer durch mindestens einen an dem Ringabschnitt befestigten, radial in die Kammer hineinragenden ersten Stützsteg und mindestens einen am Ringstutzen der Riemenscheibe befestigten und ebenfalls radial in die Kammer hineinragenden zweiten Stützsteg in Segmentabschnitte unterteilt ist, innerhalb derer Entkopplungselemente angeordnet sind, die sich in Drehrichtung an den Stützstegen abstützen.These Task is inventively characterized solved, that the axial projection at its end facing away from the damper housing a radially outward directed flange and an adjoining, extending in the direction of the damper housing Ring portion which, in one to the flange side of the axial projection towards open annular space of the pulley protrudes, so that between the ring portion on the one hand and a radially supported on the bearing ring nozzle the pulley on the other hand, a chamber for receiving the clutch formed and this chamber by at least one of the ring section attached, radially projecting into the chamber first support bar and at least one attached to the ring nozzle of the pulley and also radially projecting into the chamber second support bar in segment sections is divided within which decoupling elements are arranged, which are supported in the direction of rotation on the support webs.
Der Vorteil dieser Konstruktion liegt darin, dass die Entkopplungselemente überwiegend Druckbeanspruchungen ausgesetzt sind, so dass die Lebensdauer der entsprechenden Entkopplungselemente im Vergleich zu den bisher verwendeten, meist zugbeanspruchten Entkopplungselementen erheblich verlängert ist.Of the The advantage of this design is that the decoupling elements predominantly Compressive stresses are exposed, so that the life of the corresponding decoupling elements in comparison to the previously used, usually tensile decoupling elements is considerably extended.
Die Entkopplungselemente können innerhalb der Segmentabschnitte vorgespannt, alternativ aber auch nicht vorgespannt eingebaut sein.The Decoupling elements can biased within the segment sections, but alternatively also not be preloaded installed.
Die Entkopplungselemente selbst können aus Federn, aus Segmenten aus Poly urethan oder aus anderen geeigneten Entkopplungsmitteln bestehen.The Decoupling elements themselves can be off Springs, of poly urethane or other suitable segments Decoupling consist.
Besonders bevorzugt werden Entkopplungselemente aus Polyurethan. Dieser Werkstoff zeigt bei der hier beschriebenen Erfindung eine progressive Federkennlinie, die für das interessierende Einsatzgebiet von besonderem Wert ist.Especially Preference is given to decoupling elements made of polyurethane. This material shows in the invention described here a progressive spring characteristic, the for the area of interest is of particular value.
Bei gummientkoppelten Riemenscheiben ist hingegen nur eine annähernd lineare Federkennlinie darstellbar.at rubber-coupled pulleys, however, is only an approximately linear Spring characteristic can be displayed.
Das Lager ist vorteilhafterweise mit einem die Riemenscheibe axial gegenüber dem Dämpfergehäuse abstützenden Lagerflansch versehen und insgesamt aus einem geeigneten Kunststoff gefertigt. Hierdurch wird auch eine thermische Entkopplung der Riemenscheibe zum Viskosedämpfer erreicht.The Bearing is advantageously with a pulley axially opposite to the Damper housing supporting Provided bearing flange and a total of a suitable plastic manufactured. This also causes a thermal decoupling of the pulley to viscose damper reached.
