Description
Gebiet der ErfindungTerritory of invention
Spanneinheit für einen Zahnriemen-, Riemen- oder Kettentrieb einer Maschine, insbesondere einer Brennkraftmaschine, mit einem Spannrollenträger, der mittels einer Lagerstelle schwenkbar an der Maschine geführt ist, eine Befestigungsstelle für die drehbar gelagerte Spannrolle und eine Befestigungsstelle für ein Spann- und/oder Dämpfungselement aufweist. Das Spann- und/oder Dämpfungselement kann gemäß einer modifizierten Ausgestaltung auch entfallen, wobei dann in der Lagerstelle ein Feder- und/oder Dämpferelement eingebaut ist.clamping unit for one Toothed belt, belt or chain drive of a machine, in particular one Internal combustion engine, with a tension roller carrier, by means of a bearing point pivotally guided on the machine is an attachment point for the rotatably mounted tension pulley and an attachment point for a tensioning and / or damping element. The tensioning and / or damping element can according to a modified embodiment also omitted, in which case in the storage a spring and / or damper element is installed.
Hintergrund der Erfindungbackground the invention
Eine derartige, gattungsbildende Spanneinheit ist aus der DE-88 04 668 U1 bekannt. Diese Spanneinheit weist einen Spannrollenträger auf, an dem eine Spannrolle zum Spannen des Zahnriementriebes befestigt ist. Der Spannrollenträger stützt sich dabei an einer Lagerstelle an der Brennkraftmaschine ab, wobei die Spann- und Dämpfungskraft über ein Spann-/Dämpfungselement erfolgt.A such, generic clamping unit is known from DE-88 04 668 U1 known. This clamping unit has a tensioning roller carrier, attached to a tensioning roller for tensioning the toothed belt drive is. The tension roller carrier supports itself at a bearing point on the internal combustion engine, wherein the tensioning and damping force over one Clamping / damping element he follows.
Sowohl die Befestigung der Spannrolle bzw. des Innenrings der Spannrolle als auch des mit dem Spannrollenträger verbundenen Endes des Spann-/Dämpfungselements erfolgt üblicher Weise durch eine Schraubverbindung. Die Krafteinleitung erfolgt dabei über die Auflagefläche der Innenringe an dem Spannrollenträger, so dass im Wesentlichen eine kraftschlüssige Verbindung vorliegt. Diese Art der Verbindung mittels Schrauben ist relativ teuer und bei der Montage auch zeitaufwändig.Either the attachment of the tension roller or the inner ring of the tension roller as well as connected to the tension roller carrier end of the tensioning / damping element is more usual Way through a screw connection. The force is applied over it the bearing surface the inner rings on the tension roller carrier, so that essentially one frictional Connection exists. This type of connection by means of screws is relatively expensive and time consuming in the assembly.
Aufgabe der Erfindungtask the invention
Aufgabe der Erfindung ist es daher, die gattungsbildende Spanneinheit zu verbessern, zu verbilligen und zu vereinfachen.task The invention is therefore to the generic type clamping unit improve, cheapen and simplify.
Zusammenfassung der ErfindungSummary the invention
Die Aufgabe der Erfindung wird dadurch gelöst, dass die Befestigungsstellen für die Spannrolle und das Spann- und/oder Dämpfungselement je eine Befestigungsachse aufweisen, die einstückig mit dem Spannrollenträger hergestellt sind.The The object of the invention is achieved in that the attachment points for the Tension pulley and the tensioning and / or damping element each have a fastening axis have, in one piece with the tension roller carrier are made.
Diese Ausgestaltung der Befestigungsstelle bzw. Befestigungsstellen ist vorteilhaft, weil sowohl über die Spannrolle als auch das Spann- und/oder Dämpfungselement geringe quer zur Druckrichtung wirkende Kraftkomponenten vorhanden sind. Die Kraftübertragung erfolgt nicht mehr kraft- sondern formschlüssig von der Spannrolle und dem Spann- und/oder Dämpfungselement unmittelbar auf den Spannrollenträger. Alternativ dazu bietet es sich an, eine Befestigungsstelle oder Befestigungsstellen zu schaffen, die jeweils eine Spannrolle und ein Dämpfungselement umfasst.These Design of the attachment point or attachment points is advantageous because both over the tensioner as well as the clamping and / or damping element small transversely Force components acting to the compression direction are present. The power transmission does not force but form-fitting of the tensioner and the tensioning and / or damping element directly on the tension roller carrier. Alternatively, offers it is to create an attachment point or attachment points, each comprising a tension roller and a damping element.
In vorteilhafter Weise weist die Lagerstelle eine Traghülse auf, die einstückig mit dem Spannrollenträger hergestellt ist. Je nach dem, um welche Ausgestal tung der Lagerstelle, also mit oder ohne Feder-Dämpfer-Element, es sich handelt, sind die Formgestaltung und die Abmessung der Traghülse unterschiedlich.In Advantageously, the bearing point on a support sleeve, the one-piece with the tension roller carrier is made. Depending on the design of the depository, So with or without spring-damper element, it is, the shape design and the size of the support sleeve are different.
Durch die zuvor beschriebenen Merkmale der Erfindung wird ein Spannrollenträger zur Verfügung gestellt, der einfach in der Herstellung ist und alle erforderlichen Elemente, wie Lagerstelle und Befestigungsstellen integral beinhaltet.By the features of the invention described above is a tension roller carrier for disposal which is easy to manufacture and all required Elements, such as bearing and attachment points integrally includes.
Der Spannrollenträger kann als Tiefziehteil hergestellt sein, wobei die Befestigungsachse bzw. Befestigungsachsen in den Spannrollenträger eingepresst sein können, um den Tiefziehvorgang zu vereinfachen. Es handelt sich dabei vorzugsweise um eine Ausgestaltung als Stahl-Tiefziehteil.Of the Utility Carrier can be made as a deep-drawn part, wherein the mounting axis or attachment axes can be pressed into the tension roller carrier to to simplify the thermoforming process. These are preferably an embodiment as a steel deep-drawn part.
Der Spannrollenträger kann aber auch in vorteilhafter Weise als Leichtmetallgussteil, insbesondere Aludruckgussteil, hergestellt sein. Dann sind integral die Lagerstelle mit Traghülse und die Befestigungsstelle oder Befestigungsstellen mit Befestigungsachsen versehen.Of the Utility Carrier but can also be used advantageously as a light metal casting, in particular aluminum diecasting, be prepared. Then they are integral the bearing with support sleeve and the attachment point or attachment points with attachment axes Mistake.
Da sowohl bei der Spannrolle als auch bei dem Spann- und Dämpfungselement, wie bereits angesprochen, relativ geringe Axialkräfte vorliegen, kann die axiale Festlegung der Spannrolle, insbesondere deren Innenring, und des Spann- und/oder Dämpfungselements, insbesondere dessen Führungs- und/oder Dämpfungshülse(n), mittels einer Zahnscheibe erfolgen, deren Zähne sich auf der/den Befestigungsachsen abstützen. Derartige Zahnscheiben sind prinzipiell bekannt. Dabei ist der Innendurchmesser der Zähne der Zahnscheibe etwas kleiner als der Durchmesser der Befestigungsachse bzw. der Befestigungsachsen, so dass die Zahnscheibe mit den Zähnen sich beim Aufschieben auf die Befestigungsachse verbiegt. Dabei stützen sich die Zähne mit ihren Kanten auf der jeweiligen Befestigungsachse ab.There both in the tensioner and in the tensioning and damping element, As already mentioned, relatively low axial forces can exist the axial fixing of the tensioning roller, in particular its inner ring, and the tensioning and / or damping element, in particular its guide and / or damping sleeve (s), take place by means of a toothed wheel whose teeth are on the / the attachment axes support. Such toothed disks are known in principle. Here is the inner diameter the teeth the toothed disc is slightly smaller than the diameter of the mounting axis or the attachment axes, so that the toothed disc with the teeth themselves bends when pushed onto the mounting axis. This is supported by the Teeth with their edges on the respective mounting axis.
Um die an sich ausreichende Axialstützkraft der zuvor beschriebenen Zahnscheibe(n) zu erhöhen, kann auf der bzw. den Befestigungsachsen noch je eine Ringnut angebracht sein, die so angeordnet ist, dass die Zähne der Zahnscheibe beim Aufschieben in die Ringnut einrasten und dadurch zur Aufnahme von weit größeren Axialkräften geeignet sind.Around the sufficient axial support force of the To increase previously described toothed disc (s), on the or the Fastening axes still be attached an annular groove, the so is arranged that the teeth engage the toothed disc when pushed into the annular groove and thereby suitable for receiving much larger axial forces are.
