Aufgabe der ErfindungTask of invention
Der Erfindung liegt die Aufgabe zugrunde, eine für einen Nebenaggregateantrieb einer Brennkraftmaschine geeignete Freilaufriemenscheibe gegenüber dem Stand der Technik, insbesondere hinsichtlich des Bauraumbedarfs, weiter zu verbessern.Of the Invention is based on the object, one for an accessory drive an internal combustion engine suitable freewheeling pulley against the State of the art, in particular with regard to the space requirement, continue to improve.
Zusammenfassung der ErfindungSummary the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Freilaufriemenscheibe mit den Merkmalen des Anspruchs 1. Wesentliches Funktionselement dieser Freilaufriemenscheibe ist eine Freilaufeinheit, welche radial zwischen einer Nabe und einer Antriebsscheibe angeordnet ist, wobei die Nabe drehfest mit einer Eingangswelle eines Nebenaggregats einer Brennkraftmaschine verbindbar ist, während die Antriebsscheibe von der Brennkraftmaschine antreibbar ist. Diejenige Stirnseite der Nabe, auf welcher das Nebenaggregat angeordnet ist, wird als erste Stirnseite bezeichnet. Im Gegensatz zu dieser Stirnseite ist die zweite Stirnseite der Nabe mit einem mit der Antriebsscheibe verbundenen Deckel abdeckbar. Zwischen einem Innenring und einem Außenring der Freilaufeinheit ist ein Ringraum gebildet, in welchem Klemmelemente, insbesondere Klemmrollen, angeordnet sind. Der Außenring weist zumindest auf der ers ten Stirnseite einen umlaufenden Bord auf. Axial neben diesem Bord befindet sich auf dessen den Klemmelementen zugewandter Seite, das heißt auf der Innenseite des Bordes, ein Dichtring. Überraschenderweise hat sich gezeigt, dass damit der Bauraumbedarf der Freilaufriemenscheibe in axialer Richtung im Vergleich zu einer herkömmlichen Freilaufriemenscheibe, welche eine außerhalb des Bordes des Außenrings auf der ersten Stirnseite angeordnete Dichtung aufweist, signifikant reduziert ist.These The object is achieved by a freewheeling pulley with the features of claim 1. Essential Functional element of this freewheeling pulley is a freewheel unit, which arranged radially between a hub and a drive pulley is, wherein the hub rotationally fixed to an input shaft of an auxiliary unit Internal combustion engine is connectable while the drive pulley of the internal combustion engine is drivable. The front of the Hub on which the accessory is arranged, is the first Designated front side. In contrast to this front page is the second end of the hub with a connected to the drive pulley Cover can be covered. Between an inner ring and an outer ring the freewheel unit is formed an annular space in which clamping elements, in particular clamping rollers are arranged. The outer ring has at least on the ers th front page a rotating board on. Axial next to this board is on the clamping elements facing side, that is on the inside of the board, a sealing ring. Surprisingly, it has become shown that so that the space requirement of the freewheeling pulley in axial direction compared to a conventional freewheel pulley, which one outside the Bordes of the outer ring On the first end face disposed seal, significantly is reduced.
In bevorzugter Ausgestaltung ist der Dichtring in einer dem Bord axial unmittelbar benachbarten, im Außenring gebildeten Nut gehalten. Auf einfache Weise ist der Dichtring durch Bördeln am Außenring fixierbar. Ein ringförmiger, metallischer Kern des Dichtrings kann am Bord anliegen oder von diesem geringfügig beabstandet sein. Eine sich zum Innenring erstreckende Dichtlippe des Dichtrings greift vorzugsweise in den axialen Bauraum des Bordes ein. Mit anderen Worten: Es existiert mindestens eine Radiallinie, welche sowohl den Bord als auch die Dichtlippe schneidet. Die Begriffe „axial" und „radial" sind stets auf die Rotationsachse der Freilaufriemenscheibe bezogen.In preferred embodiment, the sealing ring in a the board is axially immediately adjacent, in the outer ring formed groove held. In a simple way, the sealing ring is through beading on the outer ring fixable. An annular, metallic core of the sealing ring can rest on board or from this slightly be spaced. A sealing lip extending to the inner ring the sealing ring preferably engages in the axial space of the Bordes one. In other words, there is at least one radial line which cuts both the board and the sealing lip. The terms "axial" and "radial" are always on the Rotary axis of the freewheeling pulley based.
Die Freilaufeinheit ist vorzugsweise als Klemmrollenfreilauf mit integrierter Lagerung gestaltet, wobei zu beiden Seiten der Klemmrollen jeweils eine Reihe Wälzkörper, insbesondere Nadeln oder Rollen, angeordnet ist. Der Außenring sowie der Innenring der Freilaufeinheit sind rationell durch spanlose Umformung herstellbar.The Freewheel unit is preferably as a clamping roller freewheel with integrated Shaped storage, with one on each side of the clamping rollers Row of rolling elements, in particular Needles or rollers, is arranged. The outer ring as well as the inner ring The freewheel unit can be produced efficiently by chipless forming.
