Abstract
Description
Die Erfindung betrifft ein Gleitlager für die Kurbelwelle oder die Nockenwelle eines Verbrennungsmotors mit zwei Lagerschalen, von denen die eine in einem vom Kurbelgehäuse oder dem Zylinderkopf gebildeten Lagerstuhl angeordnet ist.The The invention relates to a plain bearing for the crankshaft or the Camshaft of an internal combustion engine with two bearing shells, from the one in a formed by the crankcase or the cylinder head Bearing chair is arranged.
Um die Dauerbeständigkeit eines solchen Gleitlagers zu gewährleisten und damit eine wirtschaftlich sinnvolle Lebensdauer zu erzielen, ist eine ausreichende Schmierung desselben erforderlich. Trotz der Schmierung ist aber ein gewisser Reibungswiderstand unvermeidbar. Die durch die Drehung der Kurbelwelle oder der Nockenwelle im Gleitlager entstehende Reibung ist abhängig von der Belastung des Lagers, der Drehzahl, der Eintrittstemperatur des Schmieröls, der Durchflußmenge des Schmieröls und der Anbindung des Lagerstuhls an das Kurbelgehäuse oder den Zylinderkopf eines Verbrennungsmotors. Je höher die Temperatur der einzelnen Einflußgrößen ist, desto niedriger ist die im Gleitlager entstehende Reibung und damit die Verlustleistung des Motors. Eine Beeinflussung der Temperatur des Gleitlagers findet in dem komplexen thermodynamischen System des Verbrennungsmotors über verschiedene Mechanismen statt.
- 1. Durch die Drehbewegung der Kurbelwelle oder der Nockenwelle des Verbrennungsmotors entsteht innerhalb des Gleitlagers Wärme, die wiederum zu einer Erhöhung der lokalen Öltemperatur führt. Dies bewirkt über die Reduzierung der Viskosität des Schmieröls eine Verringerung der Reibleistung.
- 2. Durch die Befeuerung des Motors nimmt das den Motorblock durchströmende Öl Wärme auf und transportiert diese an die verschiedenen Gleitlager.
- 3. Die Durchströmung des Lagers mit Öl bewirkt bei hohen Lasten eine Kühlung des Lagers.
- 1. Due to the rotational movement of the crankshaft or the camshaft of the engine heat is generated within the sliding bearing, which in turn leads to an increase in the local oil temperature. This causes a reduction of the friction power by reducing the viscosity of the lubricating oil.
- 2. By firing the engine, the oil flowing through the engine block absorbs heat and transports it to the various plain bearings.
- 3. The flow of oil through the bearing causes cooling of the bearing at high loads.
Um
bei einem Kaltstart durch eine Erhöhung der Temperatur des Gleitlagers
die Lagerreibung zu reduzieren, ist es bekannt, das Öl im Hauptölkanal elektrisch
zu erwärmen
(
Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Gleitlager dahingehend zu verbessern, daß es möglichst rasch die optimale Betriebstemperatur erreicht.Of the Invention is based on the object, the generic plain bearing to improve it preferably quickly reaches the optimum operating temperature.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß zwischen der Lagerschale und dem Lagerstuhl eine Isolationsschicht aus einem Material mit einer im Vergleich zu Aluminium, Stahl oder eine Legierung für Gleitlager geringeren Wärmeleitfähigkeit angeordnet ist.According to the invention this Task solved by that between the bearing shell and the bearing block an insulating layer of a Material with one compared to aluminum, steel or an alloy for plain bearings lower thermal conductivity is arranged.
Durch diese Isolationsschicht wird ein Wärmestrom von der Lagerschale zu dem aus Aluminium oder Grauguß, also einem Material mit hoher Wärmeleitfähigkeit bestehenden Lagerstuhl weitgehend unterbunden. Die durch die Reibung entstehende Energie steht somit zur Erwärmung des Schmieröls voll zur Verfügung. Das Schmieröl erreicht daher nach einem Kaltstart des Motors rasch seine optimale Betriebstemperatur. Die von der Viskosität des Schmieröls abhängige Lagerreibung nimmt demzufolge bei einem Kaltstart des Verbrennungsmotors rasch ab, was zu einer Verringerung des Kraftstoffverbrauchs führt. Dieser Vorteil macht sich insbesondere dann bemerkbar, wenn der Verbrennungsmotor bei tiefen Außentemperaturen gestartet wird.By this insulation layer becomes a heat flow from the bearing shell to the aluminum or gray cast iron, so a material with high thermal conductivity existing storage chair largely prevented. The friction Resulting energy is thus fully to the heating of the lubricating oil Available. The lubricating oil therefore reaches its optimal after a cold start of the engine Operating temperatur. The dependent on the viscosity of the lubricating oil bearing friction Consequently, it takes quickly in a cold start of the engine which leads to a reduction in fuel consumption. This Advantage is particularly noticeable when the internal combustion engine at low outside temperatures is started.
Als Material für die Isolationsschicht können beispielsweise schwach wärmeleitende Metalllegierungen (Metal Based Thermal Barrier Coatings) benutzt werden. Solche schwach wärmeleitenden Metalllegierungen können auf den Lagerstuhl aufgedampft oder aufgesprüht werden.When Material for the insulation layer can, for example weak heat-conducting Metal alloys (Metal Based Thermal Barrier Coatings) used become. Such weak heat-conducting Metal alloys can vapor-deposited or sprayed onto the bearing block.
Gemäß einer Weiterbildung der Erfindung ist vorgesehen, daß zwischen der Lagerschale und der Isolationsschicht eine elektrisch beheizbare Einlage angeordnet ist. Dies ermöglicht es, das Gleitlager vor dem Starten des Verbrennungsmotors zu erwärmen bzw. während des Warmlaufs seine Erwärmung zu beschleunigen. Der Einsatz von elektrischer Energie zur Zuheizung ist zwar unwirtschaftlich, sofern der Strom mit einem Generator erzeugt wird. Im Gegensatz zu der bekannten elektrischen Erwärmung des Schmieröls hat die elektrische Beheizung der Lagerschale aber den Vorteil, daß die Energie sehr zielgerichtet genau an der Stelle eingesetzt werden kann, wo sie auch tatsächlich benötigt wird. Damit ist der Energieaufwand gering.According to one Further development of the invention is provided that between the bearing shell and the insulation layer arranged an electrically heatable insert is. this makes possible it to heat the plain bearing before starting the internal combustion engine or while warming up its warming to accelerate. The use of electrical energy for heating is uneconomic, provided the power with a generator is produced. In contrast to the known electrical heating of the lubricating oil has the electrical heating of the bearing shell but the advantage that the energy very purposefully can be used exactly at the point where she too needed becomes. Thus, the energy consumption is low.
Die Erfindung wird nachfolgend anhand von zwei in der Zeichnung dargestellten bevorzugten Ausführungsbeispielen näher erläutert. Es zeigt:The Invention will be described below with reference to two in the drawing preferred embodiments explained in more detail. It shows:

Die thermische Entkopplung des Gleitlagers von der Motorstruktur hat zur Folge, daß die in Wärme umgewandelte elektrische Energie zielgerichtet im Gleitlager eingesetzt wird und dort verbleibt. Der für die elektrische Zuheizung des Gleitlagers erforderliche Aufwand an elektrischer Energie ist daher gering im Vergleich zur der durch die Verringerung der Lagerreibung erzielbaren Einsparung an Kraftstoff. Eine weitere Energieeinsparung kann erreicht werden, wenn rekuperativ, z. B. in den Bremsphasen des Fahrzeugs gewonnene elektrische Energie zum Vorheizen des Gleitlagers verwendet wird.The thermal decoupling of the sliding bearing of the engine structure has with the result that the in heat converted electrical energy targeted used in plain bearings will and remains there. The for the electrical heating of the plain bearing required effort in electrical energy is therefore low compared to the through the reduction in bearing friction achievable fuel savings. Further energy savings can be achieved if recuperative, z. B. in the braking phases of the vehicle obtained electrical energy is used for preheating the sliding bearing.
Im Hinblick auf die angestrebte rasche Erwärmung des Schmieröls bei einem Kaltstart des Verbrennungsmotors kann es auch zweckmäßig sein, in der Ölzufuhr eine die Wärmeleitung verringernde Beschichtung vorzusehen.in the With regard to the desired rapid heating of the lubricating oil at a Cold start of the internal combustion engine, it may also be appropriate in the oil supply one the heat conduction to provide reducing coating.
Abweichend von den in der Zeichnung dargestellten Ausführungsbeispielen kann zusätzlich eine Isolationsschicht zwischen der oberen Lagerschale und dem (nicht gezeigten) Lagerdeckel angeordnet sein.deviant of the embodiments shown in the drawing may additionally Insulating layer between the upper bearing shell and the (not shown) bearing cover be arranged.
Wenngleich vorstehend die Lagerung einer Kurbelwelle erläutert wurde, so ist für den Fachmann erkennbar, daß grundsätzlich die gleiche Ausbildung eines Gleitlagers auch zur Lagerung einer Nockenwelle verwendet werden kann.Although above, the bearing of a crankshaft has been explained, it will be apparent to those skilled in the art, that basically the same design of a plain bearing for the storage of a camshaft can be used.
