Description
Die vorliegende Erfindung betrifft die Anordnung des Druckfilters in einem stufenlosen Automatgetriebe, insbesondere einem Umschlingungsgetriebe, gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to the arrangement of the pressure filter in a continuously variable automatic transmission, in particular a belt transmission, according to the generic term of claim 1
Ein stufenloses Umschlingungsgetriebe besteht üblicherweise u.a. aus einer Anfahreinheit, vorzugsweise einem Wandler, einer Vorwärts/Rückwärtsfahreinheit bzw. einem Wendesatz, einer Zwischenwelle, einem Differential, aus hydraulischen und elektronischen Steuereinrichtungen sowie aus einem Variator.One stepless belt transmission is usually u.a. from one Starting unit, preferably a converter, a forward / reverse drive unit or a reversing set, an intermediate shaft, a differential hydraulic and electronic control devices as well as one Variator.
Der Variator umfasst bei derartigen Getrieben nach dem Stand der Technik eine Primärseite, die mit der Antriebswelle verbunden ist, und eine Sekundärseite, welche jeweils paarweise angeordnete Kegelscheiben umfassen. Eine der Kegelscheiben ist in axialer Richtung feststehend angeordnet, wobei die andere axial verschiebbar angeordnet ist. Des weiteren ist ein Variator mit einem momentenübertragenden Umschlingungselement versehen, das zwischen den beiden Kegelscheibenpaaren umläuft. Als Umschlingungselement wird üblicherweise ein Schubgliederband, eine Zugkette oder ein Riemen verwendet. Die aktuelle Übersetzung des Getriebes wird durch den Laufradius des Umschlingungselementes definiert, der wiederum eine Funktion der axialen Position der Kegelscheiben der Primär- bzw. Sekundärseite zueinander ist.Of the Variator includes in such transmissions according to the prior art a primary page that is connected to the drive shaft, and a secondary side, which each comprise paired conical disks. A the conical disks is fixed in the axial direction, the other being arranged axially displaceable. Furthermore is a variator with a torque-transmitting belt element provided, which circulates between the two cone pulley pairs. As wrapping element becomes common used a push belt, a pull chain or a belt. The current translation of the transmission is determined by the running radius of the belt which in turn defines a function of the axial position of the conical disks the primary or secondary side to each other.

Nach dem Stand der Technik wird die axiale Position der Kegelscheiben der Primär- bzw. Sekundärseite zueinander hydraulisch eingestellt. Hierbei wird ein primärer und ein sekundärer Hydraulikdruck auf die beweglichen Kegelscheiben aufgebracht, derart, dass der axiale Abstand der Kegelscheiben eines Kegelscheibenpaares zueinander als Funktion des Druckes einstellbar ist.To In the prior art, the axial position of the conical disks the primary or secondary side hydraulically adjusted to each other. Here is a primary and a secondary one Hydraulic pressure applied to the movable conical disks, in this way that the axial distance of the conical disks of a cone pulley pair each other is adjustable as a function of pressure.
Es hat sich als notwendig erwiesen, in derartigen stufenlos verstellbaren Getrieben einen Druckfilter einzubauen, um Partikel, die mit dem Saugfilter nicht erfasst werden, zu filtern. Hierbei werden nach dem Stand der Technik diese Filter üblicherweise im Kühlerkreislauf der Hydraulik derart angeordnet, dass sie von außen montierbar sind, was die Austauschbarkeit gewährleisten soll. In nachteiliger Weise wird bei dieser Konstruktion ein Deckel zur Abdeckung des Filters nach außen benötigt, der zusätzlich abgedichtet sein muss, was die Herstellungs- und Montagekosten des Getriebes negativ beeinflusst.It has proved necessary in such continuously variable Driven to install a pressure filter to remove particles that are mixed with the Suction filters are not detected to filter. Here are after the Prior art, these filters usually in the cooler circuit the hydraulics arranged so that they are mountable from the outside, which the Ensure interchangeability should. Disadvantageously, in this construction, a lid needed to cover the filter to the outside, which additionally sealed must be what the manufacturing and assembly costs of the transmission negatively influenced.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Anordnung des Druckfilters in einem stufenlosen Automatgetriebe anzugeben, welche im Vergleich zum Stand der Technik weniger Bauteile erfordert. Durch die erfindungsgemäße Anordnung sollen die Herstellungs- und Montagekosten des Getriebes gesenkt werden.Of the present invention is based on the object, an arrangement of the pressure filter in a continuously variable automatic transmission, which requires fewer components compared to the prior art. By the arrangement according to the invention intended to reduce the manufacturing and assembly costs of the transmission become.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere Vorteile und vorteilhafte Ausgestaltungen gehen aus den Unteransprüchen hervor.These The object is achieved by the Characteristics of claim 1 solved. Further advantages and advantageous Embodiments will become apparent from the dependent claims.
Demnach wird vorgeschlagen, den Druckfilter auf die Lebensdauer des Getriebes auszulegen, so dass kein Austausch über die Lebensdauer erforderlich ist. Dies hat zur Folge, dass die Zugänglichkeit von außen nicht erforderlich ist, so dass gemäß der Erfindung vorgesehen ist, dass der Druckfilter im Inneren des Gehäuses des Getriebes angeordnet ist. Vorzugsweise ist der Druckfilter nicht im Kühlerkreislauf angeordnet.Therefore It is suggested that the pressure filter on the life of the transmission be interpreted so that no replacement over the life required is. As a result, accessibility from the outside is not is required, so that according to the invention provided is that the pressure filter inside the housing of the Transmission is arranged. Preferably, the pressure filter is not in the cooler circuit arranged.
Gemäß einer besonders vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Steuergerät der Hydraulik als Deckel für den Filterraum und den Ölrücklauf dient. Hierbei werden Filterraum und Ölrücklauf direkt durch die Kanalplatte der Steuerung der Hydraulik abgedeckt.According to one particularly advantageous embodiment of the invention is provided that the controller the hydraulics as a cover for the filter chamber and the oil return is used. Here are filter room and oil return directly covered by the channel plate of the control of the hydraulics.
Durch die erfindungsgemäße Konzeption wird eine signifikante Kostensenkung erzielt, da ein Deckel, ein Stutzen, drei O-Ringe sowie die benötigten Schrauben entfallen. Des weiteren werden in vorteilhafter Weise Dichtstellen nach außen vermieden.By the concept of the invention is achieved a significant cost reduction, since a lid, a neck, three O-rings as well as the needed Screws omitted. Furthermore, be in an advantageous manner Sealing points to the outside avoided.
Die Erfindung wird im Folgenden anhand der beigefügten Figuren beispielhaft näher erläutert. in diesen stellen dar:The The invention will be explained in more detail below by way of example with reference to the attached figures. in these represent:
