Das Zylinderschmiersystem für eine Mehrzahl von Zylindern in einer Hubkolbenbrennkraftmaschine dient zum Aufbringen von Schmiermittel in den Zylindern auf Kolbenlaufflächen mit jeweils einer Mehrzahl von Schmiermitteldüsen. Schmiermittel wird mit intermittierend fördernden Schmiermittelpumpen dosiert und pulsartig den Schmiermitteldüsen zugeführt. Antriebskomponenten der Schmiermittelpumpen sind an ein Öl leitendes Rohr angeschlossen. Jedem Zylinder ist ein Schmiermodul mit einer Schmiermittelpumpe zugeordnet.

Lubricant is dosed with intermittently pumping lubricant pumps and fed in pulses to the lubricant nozzles. Drive components of the lubricant pumps are connected to an oil-conducting pipe. Each cylinder is assigned a lubrication module with a lubricant pump. The lubricant pump forms a mechanically stable body, through which an integration of various organs is made.

Das Zylinderschmiersystem dient dazu, für eine Mehrzahl von Zylindern 8 in einer Hubkolbenbrennkraftmaschine, insbesondere Zweitakt-Grossdieselmotor mit Längsspülung, Schmiermittel (oder Zylinderöl) in den Zylindern 8 auf Kolbenlaufflächen 80 mit jeweils einer Mehrzahl von Schmiermitteldüsen 7 aufzubringen. In der eingangs genannten
Das Schmiersystem umfasst ausser den Schmiermitteldüsen eine Dosiereinheit und eine Ansteuereinrichtung (hier nicht dargestellt). Die Dosiereinheit ist eine intermittierend fördernde Schmiermittelpumpe, mit der das Schmiermittel dosiert und pulsartig den Schmiermitteldüsen zugeführt wird. Antriebskomponenten der Schmiermittelpumpe sind an ein Servo- oder Zylinderöl leitendes Rohr angeschlossen. Dieses Öl leitende Rohr kann einwandig oder als Doppelwandrohr ausgebildet sein. Nachfolgend wird die Ausführungsform mit dem Doppelwandrohr und dem Servoöl beschrieben. Diese Beschreibung gilt aber auch weitgehend, d.h. entsprechend angepasst, wenn das Öl leitende Rohr einwandig ist und anstelle des Servoöls das Zylinderöl, also das Schmiermittel verwendet wird. Die Antriebskomponenten umfassen einen Druckübersetzer und eine Einrichtung, mit der das gepumpte Schmiermittel gleichmässig auf einzelne Zuleitungen 12 und somit auf die einzelnen Schmiermitteldüsen eines zugeordneten Zylinders 8 verteilt wird.The lubrication system comprises, in addition to the lubricant nozzles, a metering unit and a drive device (not shown here). The dosing unit is an intermittently pumping lubricant pump, with which the lubricant is metered and fed in pulses to the lubricant nozzles. Drive components of the lubricant pump are connected to a servo or cylinder oil conducting pipe. This oil-conducting pipe can be formed single-walled or as a double wall pipe. Hereinafter, the embodiment with the double-wall pipe and the servo oil will be described. However, this description also applies largely, ie adapted accordingly, when the oil-conducting pipe is single-walled and instead of the servo oil the Cylinder oil, so the lubricant is used. The drive components comprise a pressure booster and a device with which the pumped lubricant is uniformly distributed to
Das Servoöl ist ein hydraulisches Arbeitsmittel, das beispielsweise mit einem Druck von 50 bar in einem zentralen Rohr des Doppelwandrohrs gefördert wird. Mit dem Ringraum zwischen dem zentralen Rohr und einem Mantelrohr, der leer ist, kann das zentrale Rohr bezüglich Leckage überwacht werden.The servo oil is a hydraulic working fluid, which is conveyed, for example, with a pressure of 50 bar in a central tube of the double wall pipe. With the annulus between the central tube and a jacket tube that is empty, the central tube can be monitored for leakage.
Das Schmiermittel wird in die Schmiermitteldüse 7 mittels der Dosiereinheit und jeweils durch die separate Zuleitung 12 eingespeist. Die Zufuhr von Schmiermittel wird bei einem Arbeitsdruck durchgeführt, der auf den Betrieb der Hubkolbenbrennkraftmaschine angepasst ist. Die Zufuhr kann nach einem vorgebbaren Schema erfolgen; oder sie kann in Abhängigkeit von verschiedenen Betriebsparametern, wie z.B. der Drehzahl, der Last, der Zylindertemperatur, der Dicke des Schmierfilms im Zylinder 8 oder anderer Betriebsparametern eingestellt werden. Die Schmiermitteldüse 7 des beschriebenen Ausführungsbeispiels weist ein Ventil 72 auf, das ein in bekannter Weise federbelastetes Ventil 72 ist. Dabei ist das Ventil 72 so einstellbar, dass es unter Einwirkung des Arbeitsdrucks des in der Zuleitung 12 anstehenden Schmiermittels spontan öffnet, so dass das Schmiermittel aus der Zuleitung 12 in die Schmiermitteldüse 7 stossartig einströmt und durch die Austrittsöffnung 73 fächerartig auf die Kolbenlauffläche 80 austritt (oder bei einem anderen Düsentyp beispielsweise in Tropfenform abgegeben wird). Das Ventil 72 wirkt auch als Rückschlagventil, das gegen ein Rückströmen des Schmiermittels aufgrund eines zylinderseitigen Überdrucks schützt. Rückschlagventile können auch zwischen der Schmiermittelpumpe und den Zuleitungen 12 angeordnet sein, insbesondere bei Düsentypen, die nicht selbst die Funktion eines Rückschlagventils aufweisen.The lubricant is fed into the
Neben den bereits genannten Betriebsparametern kann auch beispielsweise die Qualität des Schmiermittels und/oder die Qualität des Treibstoffs oder anderer Betriebsstoffe sowohl den Zeitpunkt, als auch die Menge des zugeführten Schmiermittels mitbestimmen. Die Betriebsparameter können von nicht gezeigten Sensoren eingelesen und über Datenleitungen der Ansteuereinrichtung, die frei programmierbar ist, zugeführt werden, so dass die Dosiereinrichtung entsprechend gesteuert oder geregelt wird.In addition to the operating parameters already mentioned, for example, the quality of the lubricant and / or the quality of the fuel or other fuels can also determine the time as well as the amount of lubricant supplied. The operating parameters can be read by sensors, not shown, and supplied via data lines of the drive device, which is freely programmable, so that the metering device is controlled or regulated accordingly.
Beim erfindungsgemässen Schmiersystem ist jedem Zylinder 8 ein Schmiermodul mit einer Schmiermittelpumpe (inklusive Verteilereinrichtung) zugeordnet.

Der Grundkörper 2, in dem die nicht dargestellte Schmiermittelpumpe enthalten ist, hat zwei Anschlussstellen 6a und 6b für das Servoöl. An diesen wird das zentrale Rohr 161 des Doppelwandrohrs 16 (mit Mantelrohr 162) an ein Rohrende 60 des Grundkörpers 2 beispielsweise mit einer Schraubverbindung angeschlossen. Flansche 163 an den Enden des Mantelrohrs 162 werden auf den Grundkörper 2 aufgeschraubt. Im Innern des Grundkörpers 2 ist ein Kanal 61 mit einer T-förmigen Verzweigung und einer Abzweigung 62 für das Servoöl integriert. Dieser Kanal 61 verbindet die Anschlussstellen 6a und 6b, während die Abzweigung 62 eine durch das Ventil 5 gesteuert verschliessbare Verbindung zu den Antriebskomponenten der Schmiermittelpumpe herstellt. Dank diesem Kanal 61 mit Abzweigung 62 wird kein T-Stück in der externen Servoöl-Leitung (dem "Rail") benötigt, wie es bei vorbekannten Schmiersystemen der Fall ist. Dank dieser Lösung verringert sich die Anzahl der erforderlichen Flanschverbindungen von vier auf zwei, was eine namhafte Kosteneinsparung bedeutet. Die Doppelpfeile 6 in
Jede lokale Steuerungseinheit 3 bildet einen intelligenten Knotenpunkt eines übergeordneten Steuerungssystems 100, das anhand der
Das übergeordnete Steuerungssystems 100 umfasst mindestens eine globale Steuerung 10, Speisungsleitungen 102 für den Energiebedarf und mindestens einen Feldbus 101, insbesondere einen CAN-Bus. Die lokalen Steuerungseinheiten 3 der Module 1 sind an die Speisungsleitungen 102 (Verbindungen 21, 22) und an den Feldbus (Verbindungen 31, 32) angeschlossen. Mit dem übergeordneten Steuerungssystem 100 stellt der Feldbus eine Verbindung her, über die ein Datenaustausch zwischen den lokalen Steuerungseinheiten 3 und der globalen Steuerung 10 erfolgen kann. Mit Vorteil sind aus Gründen der Redundanz die Speisungsleitungen und der Feldbus doppelt ausgeführt. Ebenso sind zwei globale Steuerungen 10 vorgesehen. Der Feldbus verknüpft auch die einzelnen Steuerungseinheiten 3, zwischen denen auch ein Datenaustausch stattfinden kann. In
Wie in
Die Steuerung 10 des übergeordneten Steuerungssystems 100 ist frei programmierbar, so dass die Schmiermittelpumpe derart steuer- oder regelbar ist, dass die Menge und/oder der Zeitpunkt des geförderten Schmiermittels in Abhängigkeit von den bereits genannten Betriebsparametern einstellbar ist.The
Mit dem Drucksensor 4 wird die intermittierende Förderung des Schmiermittels hinsichtlich Zeitpunkt der Abgabe und erzeugtem Druckstoss überwacht. In Bezug auf Sollwerte, die vorgegeben sind oder die von weiteren Parameteren abhängen können, wird das übergeordnete Steuerungssystem geregelt. Mit dem Drucksensor 4 gemessenen Grössen werden zumindest teilweise über die lokale Steuerungseinheit als Daten 310 an das übergeordnete Steuerungssystem 100 zur Überwachung weiter geleitet, so dass gegebenenfalls erforderliche Abhilfemassnahmen aktiviert und/oder ein Alarm ausgelöst werden kann. In der Gegenrichtung empfangen die lokalen Steuerungssysteme 3 Daten 103 von der übergeordneten Steuerung 10.With the pressure sensor 4, the intermittent delivery of the lubricant is monitored in terms of timing of delivery and generated pressure surge. With respect to setpoints which are predetermined or which may depend on other parameters, the higher-level control system is regulated. Sizes measured with the pressure sensor 4 are at least partially forwarded via the local control unit as
