Hintergrund der Erfindungbackground the invention
Aufgabe der Erfindung ist es daher, eine Baueinheit der vorgenannten Art zu schaffen, bei welcher die zitierten Nachteile beseitigt sind.task The invention is therefore an assembly of the aforementioned type to create, in which the cited disadvantages are eliminated.
Lösung der AufgabeSolution of task
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die gelenkige Verbindung der Baueinheit über eine den Schlepphebel an einer Querbohrung seines einen Ende durchragende Achse dargestellt ist, auf welcher Achse gleichzeitig der Kopf des Abstützelements mit einem dessen Längsachse orthogonal schneidenden Lagerauge verläuft.According to the invention this Task solved by that the articulated connection of the unit via a rocker arm a transverse bore of its one end protruding axis shown is, on which axis at the same time the head of the support element with a longitudinal axis orthogonal cutting bearing eye runs.
Somit sind die eingangs zitierten Nachteile wirkungsvoll beseitigt. Aufgrund der gelenkigen Verbindung, die vorzugsweise als Wälz- bzw. alternativ auch als Gleitverbindung ausgelegt ist, ist die Reibung im Ventiltrieb minimiert. Zudem kann es nicht mehr dazu kommen, dass der Schlepphebel vom Kopf des Abstützelements, wie vorbeschrieben, abrutscht. Außerdem ist eine einfache Möglichkeit einer Lieferung einer vormontierten Baueinheit zum Motorenhersteller geschaffen, was dessen Montagekosten senkt.Consequently the cited disadvantages are effectively eliminated. by virtue of the articulated connection, preferably as Wälz- or Alternatively designed as a sliding connection, the friction minimized in the valve train. In addition, it can no longer happen that the rocker arm from the head of the support element, as described above, slip. Furthermore is an easy way a delivery of a preassembled unit to the engine manufacturer created, which reduces its installation costs.
Die erfindungsgemäße Wälzlagerung, beispielsweise eine Nadellagerung, kann im Bereich des Lagerauges des Kopfes des Abstützelements appliziert werden, wobei dann die Achse mit ihren endseitigen Stümpfen in den Bohrungen des Schlepphebels fest verlaufen soll. Hier bieten sich beispielsweise Verstemmungen, Verschweißungen, Schrumpf- oder Einpressverbindungen etc. an.The rolling bearing according to the invention, For example, a needle bearing, can in the area of the bearing eye applied to the head of the support element be, in which case the axis with their end stumps in the holes of the rocker arm should be fixed. Offer here For example, caulking, welding, shrink or press-fit etc. at.
Zwar ist eine mittige Aufnahme des Kopfes des Abstützelements mit Lagerauge in Bezug auf den Schlepphebel insbesondere vorgesehen, denkbar ist es jedoch auch, den Schlepphebel mit einer diesen seitlich überragenden Achse zu versehen, auf welcher dann das Abstützelement verläuft.Though is a central recording of the head of the support element with bearing eye in With respect to the rocker arm provided in particular, it is conceivable but also, the drag lever with a laterally projecting this To provide axis on which then runs the support element.
Eine besonders bauraumsparende Variante liegt dann vor, wenn der Kopf des Abstützelements mit zwei sich diametral gegenüberliegenden Längsanflachungen versehen wird, aus denen dann die Achse mit ihren Stümpfen ragt, welche Stümpfe wiederum in sich diametral gegenüberliegenden Querbohrungen am einen Ende des Schlepphebels aufgenommen sind.A particularly space-saving variant is present when the head of the support element with two diametrically opposed longitudinal flats is provided, from which then the axis protrudes with their stumps, which stumps turn in diametrically opposite transverse bores recorded at one end of the finger lever.
Der Schlepphebel soll zweckmäßigerweise aus einem Leichtbauwerkstoff wie Blech oder einem ähnlich geeigneten Werkstoff dargestellt sein. Besonders vorteilhaft ist es, wenn der Schlepphebel einen U-förmigen Querschnitt aufweist und stanz-biegetechnisch (keine Bedingung) beispielsweise aus Bandmaterial gefertigt ist.Of the Drag lever should expediently a lightweight material such as sheet metal or a similar suitable material be shown. It is particularly advantageous if the drag lever a U-shaped Cross-section and stamping and bending technology (no condition) is made for example of strip material.
In Fortbildung der Erfindung ist es vorgeschlagen, das Abstützelement hydraulisch wirkend auszulegen, wobei dann dessen Kopf Bestandteil eines relativ zum Gehäuse axial beweglichen Druckkolbens ist. Besonders in diesem Fall, jedoch nicht ausschließlich, bieten sich einfache Schmiermaßnahmen im Gelenkbereich an. So kann, gemäß einer Weiterbildung der Erfindung, ausgehend von einem Vorratsraum des Druckkolbens, ein Pfad zu der Wälzverbindung führen. Dieser Pfad kann einerseits zur Schmierung der Wälzverbindung dienen. Andererseits kann über diesen auch im Vorratsraum akkumulierte Luft mittelbar ins Freie entweichen.In a further development of the invention, it is proposed to design the support element hydraulically acting, in which case its head is part of a relative to the housing axially movable pressure piston. Especially in this case, but not exclusively, simple lubrication in the joint area offer. Thus, according to a development of the invention, starting from a storage space of the pressure piston, a path leading to the Wälzverbindung. This path can be used on the one hand to lubricate the Wälzverbindung. On the other hand, it can also be used in the storage room mulched air escape indirectly into the open air.
Der vorgenannte Pfad kann in einem schräg verlaufenden Pfad zur Spritzölschmierung der Nockenanlauffläche fortgeführt werden. Gleichzeitig kann über diesen schrägen Pfad auch die ggf. vorhandene Luft exmittiert werden. Denkbar und vorgesehen ist es jedoch auch, ausgehend vom Vorratsraum des Druckkolbens, direkt einen schrägen Pfad zur Spritzölschmierung/Entlüftung in Richtung Nockenkontaktfläche verlaufen zu lasen. Dieser Pfad kann auch allein oder in Kombination mit einem Pfad zur Schmierung des Gelenks vorgesehen sein.Of the The aforementioned path may be in a slanted path for spray oil lubrication the cam contact surface continued become. At the same time can over this oblique Path are also the possibly existing air be discharged. Conceivable and However, it is also provided, starting from the storage space of the pressure piston, directly a weird Path for spray oil lubrication / venting in Direction cam contact surface to be lost. This path can also be alone or in combination be provided with a path for lubrication of the joint.
Alternativ ist es vorgeschlagen und vorteilhaft, das Abstützelement als rein mechanische Abstützung auszubilden, die wahlweise über eine Höhenjustiermöglichkeit wie ein Schraubmittel, wenigstens eine Einstellscheibe oder dgl. verfügt. Das Abstützelement kann auch als rein hydraulisch anhebbares Element dargestellt werden, welches in diesem Fall hydraulisch oder mechanisch (bspw. über Klinken) in seiner Höhe gehalten werden kann. Zur Schmierölversorgung des Gelenks/der Nockenanlauffläche kann auch dieses mechanische Abstützelement an eine Hydraulikmittelleitung angeschlossen werden.alternative It is proposed and advantageous, the support element as a purely mechanical support train, which optionally over a height adjustment option like a screw means, at least one dial or the like. features. The support element can also be represented as a purely hydraulically liftable element, which in this case hydraulically or mechanically (eg via latches) in its height can be held. To the lubrication oil supply of the joint / the Cam contacting surface can also this mechanical support element to a hydraulic medium line be connected.
Schließlich ist es Gegenstand eines Verfahrensanspruchs, dass die Baueinheit (Schlepphebel-Abstützelement) komplett vormontiert zum Motorenhersteller geliefert und dann anschließend in den Zylinderkopf der Brennkraftmaschine eingebaut wird. Dies senkt die Montagekosten beim Motorenhersteller. Zum anderen kann es, aufgrund der festen Verbindung durch die Achse, vor einer endgültigen Nockenwellenmontage und Inbetriebnahme der Brennkraftmaschine nicht mehr zu einem Abkippen des Schlepphebels vom Kopf des Abstützelements kommen.Finally is it is the subject of a method claim that the structural unit (drag lever support element) completely pre-assembled to the engine manufacturer and then delivered in the cylinder head of the internal combustion engine is installed. This lowers the installation costs at the engine manufacturer. For another, it may, due the fixed connection through the axle, before a final camshaft assembly and commissioning of the internal combustion engine is no longer a dump of the finger lever come from the head of the support element.
