Description
Die Erfindung betrifft eine Brennkraftmaschine mit einem in einem Kurbelgehäuse angeordneten Steuertrieb, der mit mindestens einem auf einer Lagerwelle angeordneten Lager drehbar gelagerten Antriebsrad ausgestattet ist. The invention relates to an internal combustion engine with a arranged in a crankcase control drive, which is equipped with at least one arranged on a bearing shaft bearing rotatably mounted drive wheel.
Über den Steuertrieb einer Brennkraftmaschine werden üblicherweise mindestens eine Nockenwelle und u.a. weitere Nebenaggregate, wie z.B. Schmiermittelpumpen, Kraftstoffpumpe angetrieben. Dementsprechend ist ein Steuertrieb üblicherweise mit mehreren Antriebs- bzw. Antriebszwischenrädern ausgestattet. Diese drehbar gelagerten Antriebs- bzw. Antriebszwischenräder müssen zwingend in den Schmiermittelkreislauf der Brennkraftmaschine einbezogen werden. Dies macht konstruktiven und Bauteil-mäßigen Aufwand erforderlich; die Aufgabe muss außerdem unter Berücksichtigung der Strömumgsbedingungen (Fliehkräfte) im Kurbelgehäuse gelöst werden. About the Steuertrieb an internal combustion engine are usually at least one camshaft and u.a. other accessories, such as Lubricant pumps, fuel pump driven. Accordingly, a timing drive is usually equipped with a plurality of drive or drive intermediate wheels. These rotatably mounted drive or intermediate drive wheels must be included in the lubricant circuit of the internal combustion engine mandatory. This makes constructive and component-moderate effort required; the task must also be solved taking into account the flow conditions (centrifugal forces) in the crankcase.
Aus dem Stand der Technik ist eine große Zahl von Lösungen für die Schmierung von Lagerungen bei Brennkraftmaschinen bekannt geworden. Die

Der Erfindung liegt die Aufgabe zugrunde, eine besonders Bauraum-sparende und gleichzeitig wirkungsvolle Schmierung einer Lagerstelle bei einem Steuertrieb einer Brennkraftmaschine zur Verfügung zu stellen. The invention has for its object to provide a particularly space-saving and at the same time effective lubrication of a bearing in a timing drive of an internal combustion engine.
Die Erfindung löst diese Aufgabe bei gelagerten Antriebsrädern eines Steuertriebs dadurch, dass die Lagerwelle mit einem axial verlaufenden Hohlraum zur Schmiermittelzuführung versehen wird, der über mindestens eine Radialöffnung zur Schmiermittelzuführung zum Lager mit der Lagerstelle verbindbar ist. The invention solves this problem with stored drive wheels of a timing drive in that the bearing shaft is provided with an axially extending cavity for supplying lubricant, which is connectable via at least one radial opening for supplying lubricant to the bearing with the bearing point.
Der axiale Hohlraum in der Lagerwelle kann zweckmäßigerweise als Axialbohrung ausgeführt sein. Die den axialen Hohlraum bzw. die Axialbohrung mit der Lagerstelle des Lagers verbindende Radialöffnung kann als Bohrung ausgeführt sein. The axial cavity in the bearing shaft may be expediently designed as an axial bore. The axial cavity or the axial bore with the bearing point of the bearing connecting radial opening can be designed as a bore.
Das Lager ist vorzugsweise als Wälzlager ausgeführt. The bearing is preferably designed as a rolling bearing.
Der axial verlaufende Hohlraum bzw. die Axialbohrung in der Lagerwelle steht vorzugsweise mit der Schmiermittelwanne im Kurbelgehäuse der Brennkraftmaschine in direkter Strömungsverbindung für das Schmiermittel. Der axial verlaufende Hohlraum bzw. die Axialbohrung in der Lagerwelle kann in bevorzugter Weitergestaltung der Erfindung an seinem einen Ende mit der Schmiermittelwanne im Kurbelgehäuse und an seinem anderen Ende mit der Schmiermittelführung in einer den Steuertrieb dichtend abschließenden Abdeckung in Strömungsverbindung stehen. The axially extending cavity or the axial bore in the bearing shaft is preferably in direct flow connection with the lubricant trough in the crankcase of the internal combustion engine for the lubricant. The axially extending cavity or the axial bore in the bearing shaft can be in a preferred embodiment of the invention at its one end with the lubricant trough in the crankcase and at its other end with the lubricant guide in a control drive sealingly final cover in flow communication.
Die Lagerwelle kann z.B. ein Zwischenrad eines Steuertriebs tragen. Mit der erfinderischen Lösung wird in konstruktiv einfacher Weise praktisch ohne zusätzliche Bauteile eine äußerst wirkungsvolle Schmierung von Lagern im engen Bauraum eines Kurbelgehäuses einer Brennkraftmaschine erreicht. The bearing shaft may e.g. carry an intermediate gear of a timing drive. With the inventive solution is achieved in a structurally simple manner virtually without additional components extremely effective lubrication of bearings in the confined space of a crankcase of an internal combustion engine.
Bei entsprechender Auslegung der Hohlräume/Bohrungen nach der Erfindung kann mit der erfinderischen Lösung selbstverständlich nicht nur die Schmierung der Lagerstellen erreicht werden, sondern auch deren Kühlung. With an appropriate design of the cavities / holes according to the invention, of course, not only the lubrication of the bearings can be achieved with the inventive solution, but also their cooling.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnung. Die Figur der Zeichnung zeigt lediglich ausschnittsweise die Lagerstelle eines Zwischenrads für einen Steuertrieb einer Brennkraftmaschine. Further advantages, features and details of the invention will become apparent from the following description of an embodiment with reference to the drawing. The figure of the drawing shows only a partial view of the bearing point of an idler gear for a timing drive of an internal combustion engine.
Ein Antriebsrad
Für den Fachmann versteht es sich von selbst, dass diese einfache und wirkungsvolle Konstruktion, die vor allem keinen zusätzlichen Bauraum erfordert, an verschiedenen Lagerstellen z.B. eines Steuertriebs einer Brennkraftmaschine Anwendung finden kann. It will be understood by those skilled in the art that this simple and effective construction, which in particular does not require any additional space, may be provided at various locations, e.g. a Steuertriebs an internal combustion engine can apply.
