Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Einrichtung zur Geräuschdämpfung einer geradverzahnten Übersetzungsstufe, insbesondere für einen Pumpenantrieb einer off axis Pumpe eines Getriebes, gemäß dem Oberbegriff des Patentanspruchs 1. Des weiteren bezieht sich die Erfindung auf ein Verfahren zur Geräuschdämpfung einer geradverzahnten Übersetzungsstufe.The The present invention relates to a noise attenuation device straight toothed translation stage, especially for a pump drive an off-axis pump of a transmission, according to the preamble of claim 1. Furthermore, the invention relates to a method for silencing a straight toothed translation stage.
Automatgetriebe weisen zur Hydraulikversorgung der Komponenten, z.B. der Schaltelemente, üblicherweise mechanisch angetriebene Pumpen auf. Hierbei sind die Pumpen in Abhängigkeit vom zur Verfügung stehenden Bauraum und den konstruktiven Gegebenheiten als inline (koaxial zu deren Antrieb angeordnete) Pumpen oder als off axis Pumpen ausgebildet; bei den off axis Pumpen wird die Pumpe über einen Stirntrieb angetrieben, der nach dem Stand der Technik üblicherweise als geradverzahnte Stufe mit einem treibenden und einem angetriebenen Rad ausgebildet ist.automatic transmission have for hydraulic supply of the components, e.g. the switching elements, usually mechanically driven pumps. Here, the pumps are dependent from the available standing space and the structural conditions as inline (coaxial with their drive arranged) pumps or as off axis Pumps formed; In the case of the off axis pumps, the pump is connected via a Spur drive driven, the state of the art usually as a straight toothed stage with a driving and a driven wheel is trained.
Die Ausbildung des Stirntriebs als geradverzahnte Stufe weist einerseits die Vorteile eines einfachen Aufbaus und geringer Kosten auf; andererseits entsteht der Nachteil, dass die während des Betriebs auftretenden Geräusche als störend empfunden werden.The Training of the spur gear as a straight toothed stage has on the one hand the advantages of a simple structure and low costs; on the other hand arises the disadvantage that during the operating noise as disturbing be felt.
Aus diesem Grunde ist vorgeschlagen worden, den Stirntrieb als schrägverzahnte Stufe auszubilden, was jedoch in nachteiliger Weise in hohen Kosten für die Verzahnung sowie in zusätzlichen Maßnahmen für die Abstützung der auftretenden Axialkräfte resultiert.Out For this reason, it has been proposed that the spinal drive be helical Form stage, but disadvantageously in high costs for the Gearing as well as in additional measures for the support the occurring axial forces results.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Geräuschdämpfung einer geradverzahnten Übersetzungsstufe anzugeben, welche die beim Betrieb einer off axis Pumpe eines Getriebes auftretenden Geräusche weitgehend reduziert. Des weiteren soll ein Verfahren zur Geräuschdämpfung einer geradverzahnten Übersetzungsstufe angegeben werden.Of the present invention is based on the object, a device for noise reduction of a straight toothed translation stage indicate which the when operating an off axis pump of a transmission occurring noises largely reduced. Furthermore, a method for noise reduction of a straight toothed translation stage be specified.
Diese Aufgabe wird für eine Einrichtung zur Geräuschdämpfung einer geradverzahnten Übersetzungsstufe durch die Merkmale des Patentanspruchs 1 gelöst. Ein Verfahren zur Geräuschdämpfung einer geradverzahnten Übersetzungsstufe ist Gegenstand des Patentanspruchs 3. Erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These Task is for a device for silencing a straight toothed translation stage solved by the features of claim 1. A method for noise reduction of a spur gear ratio is the subject of claim 3. Inventive embodiments and advantages are apparent from the dependent claims.
Demnach wird eine Einrichtung zur Geräuschdämpfung einer geradverzahnten Übersetzungsstufe, insbesondere für einen Pumpenantrieb einer off axis Pumpe eines Getriebes vorgeschlagen, welche eine Einrichtung aufweist, über die Öl in den Verzahnungseingriff der Übersetzungsstufe zwischen dem treibenden Rad und dem angetriebenen Rad eingespritzt wird.Therefore is a device for noise reduction of straight toothed translation stage, especially for proposed a pump drive an off-axis pump of a transmission, which having a device via the oil in the meshing engagement of the translation stage injected between the driving wheel and the driven wheel becomes.
Vorzugsweise ist die Einrichtung, über die Öl in den Verzahnungseingriff der Übersetzungsstufe eingespritzt wird, als Düse ausgebildet. Im Rahmen einer vorteilhaften Weiterbildung der Erfindung wird die Menge des pro Zeiteinheit eingespritzten Öls in Abhängigkeit der Drehzahl des treibenden Rades variiert.Preferably is the institution over the oil in injected the gearing engagement of the translation stage is, as a nozzle educated. Within the scope of an advantageous development of the invention the amount of oil injected per unit time is dependent the speed of the driving wheel varies.
Durch die erfindungsgemäße Konzeption wird eine signifikante Geräuschdämpfung der geradverzahnten Übersetzungsstufe erzielt, so dass die Notwendigkeit einer in hohen Kosten resultierenden schrägverzahnten Stufe in vorteilhafter Weise entfällt.By the concept of the invention is a significant noise reduction of straight toothed translation stage achieved, so the need for a helical gear resulting in high costs Stage advantageously omitted.
Die Erfindung wird im Folgenden anhand der beigefügten Figur, welche eine schematische Schnittansicht einer geradverzahnten Übersetzungsstufe für eine off-axis Pumpe eines Getriebes darstellt, beispielhaft näher erläutert.The Invention will be described below with reference to the accompanying figure, which is a schematic Sectional view of a straight toothed translation stage for an off-axis Pump represents a transmission, explained in more detail by way of example.

Selbstverständlich kann die Düse in Abhängigkeit des zur Verfügung stehenden Bauraumes und des jeweiligen Anwendungsfalles durch andere geeignete Einrichtungen ersetzt werden. Zudem kann die erfindungsgemäße Einrichtung bzw. das hier vorgestellte Verfahren auch bei einer Schrägverzahnung zur Anwendung kommen.Of course you can the nozzle dependent on of the available standing space and the particular application by others appropriate facilities are replaced. In addition, the inventive device or the method presented here even with a helical toothing for Application come.
