Description
Die Erfindung betrifft einen Torsionsschwingungsdämpfer gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a torsional vibration damper according to the preamble of the claim 1.

Durch die besagte Isolationsvorrichtung kann zwar eine Reduzierung des Wärmeflusses von der Reibfläche zur Lagerung erzielt werden, jedoch ist die Isolationsvorrichtung radial außen vollflächig vom abtriebsseitigen Dämpferelement umschlossen, während radial innen die Lagerung vollflächig zur Anlage kommt. Die Aufgabe der Reduzierung des Wärmeflusses obliegt mithin allein der Werkstoffauswahl, während diese Funktion unterstützende konstruktive Maßnahmen nicht getroffen sind. Die Folge davon ist, dass die Isolationsvorrichtung selbst einer starken Wärmebelastung ausgesetzt ist und eine Schädigung erfahren kann. Auch eine Erwärmung der Lagerung mit Schadensfolge kann nicht ausgeschlossen werden.By Although said isolation device can reduce the heat flow from the friction surface be achieved for storage, however, is the isolation device radially outside over the entire area of output side damper element enclosed while radially inside the storage over the entire surface comes to the plant. The task of reducing the heat flow It is therefore only the material selection that is responsible, while this function supports constructive measures not met. The consequence of this is that the isolation device even a strong heat load is exposed and damage can experience. Also, a warming Storage with damage consequence can not be excluded.

Der Erfindung liegt die Aufgabe zugrunde, an einem Torsionsschwingungsdämpfer mit einer Reibfläche und zumindest einer Lagerung eine einen Wärmefluß erheblich reduzierende Isolationsvorrichtung vorzusehen.Of the Invention is based on the object with a torsional vibration damper a friction surface and at least one storage a heat flow significantly reducing insulation device provided.
Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the specified in the characterizing part of claim 1 Characteristics solved.
Die Isolationsvorrichtung ist erfindungsgemäß dadurch gebildet, dass im abtriebsseitigen Dämpferelement radial zwischen der Reibfläche und der Lagerung Aussparungen vorgesehen sind, die im radialen Erstreckungsbereich von Befestigungsmitteln, die zur Anbindung des antriebsseitigen Dämpferelementes an einen Antrieb dienen, vorgesehen und mit zumindest einer Kühlrippe ausgebildet sind, die durch Umbiegung des jeweiligen Aussparungsrandes gebildet wird. Besonders intensiv sind hierbei Kühlrippen wirksam, die an den umfangsseitigen Aussparungsrändern vorgesehen sind, da diese als flächiger Vorsprung in die Bewegungsrichtung des Torsionsschwingungsdämpfers bei Rotation ragen und folglich eine erhebliche Verwirbelung des Kühlungsmediums Luft bewirken, wobei aufgrund dieser Turbulenzen der Wärmeaustausch verbessert wird. Optimal ist eine Ausgestaltung dieser Kühlrippen als Luftleitschaufel.The Isolation device according to the invention is formed by the fact that in output side damper element radially between the friction surface and the storage recesses are provided, which in the radial extension region of fasteners for connecting the drive side damper element serve to a drive, provided and with at least one cooling fin are formed by bending the respective Aussparungsrandes is formed. In this case, cooling fins are particularly effective, which are connected to the circumferential cutout edges are provided, since these as a surface Projection in the direction of movement of the torsional vibration damper Rotation protrude and consequently a considerable turbulence of the cooling medium Air cause, due to these turbulence, the heat exchange is improved. Optimal is an embodiment of these cooling fins as an air guide vane.
