Description

Vorrichtung zum Warmhalten des Schmieröles von Brennkraftmaschinen Es ist bekanntlich von großem Nachteil, wenn das Motoröl beim Start von Kraftfahrzeugen kalt ist, weil dabei seine Schmierfähigkeit beeinträchtigt ist. Es ist zwar schon bekannt, die Ölwanne einer Fahrzeugbrennkraftmaschine außen durch Wärmeisolierwände zu umschließen, um das Schmieröl warmzuhalten. Diese bekannte Vorrichtung erfüllt ihren Zweck aber nur sehr mangelhaft. Da bei stillgesetzter Maschine das Kurbelgehäuse und die Triebwerksteile verhältnismäßig rasch erkalten, gibt der Ölvorrat in der Ölwanne seine Wärme an diese Teile ab und nimmt gleichfalls verhältnismäßig rasch die Außentemperatur an.Device for keeping the lubricating oil of internal combustion engines warm It is known to be of great disadvantage if the engine oil when starting motor vehicles is cold because its lubricity is impaired. It is true known, the oil pan of a vehicle internal combustion engine outside by heat insulating walls to enclose to keep the lubricating oil warm. This known device fulfills but their purpose is very poor. Because when the machine is stopped, the crankcase and the engine parts cool down relatively quickly, the oil supply in the Oil pan from its heat to these parts and also decreases relatively quickly the outside temperature.

Dies zu verhindern ist Aufgabe der Erfindung. Diese besteht darin, bei einer Vorrichtung zum Warmhalten des Schmieröles von Brennkraftmaschinen, bei der der untere Teil der Ölwanne, in dem sich die Ansaugöffnung der Schmierölpumpe befindet, auf seinen Außenseiten von Wärmeisolierwänden umschlossen ist, den unteren Teil der Ölwanne auch nach dem Kurbelraum hin durch eine Wärmeisolierwand abzuschließen und in dieser eine durch einen Schwimmer absperrbare Öffnung vorzusehen. Dadurch wird ermöglicht, daß derjenige Anteil des Motoröles, der beim Anlassen der Maschine durch die Ölpumpe abgesaugt und den Schmierstellen zugeführt wird, für eine möglichst lange Zeitdauer nach dem Stillsetzen der Brennkraftmaschine warmgehalten wird. Die Wärmeabstrahlung nach dem Kurbelraum hin ist weitgehend unterbunden. Der untere Teil der Ölwanne ist praktisch immer vollständig mit Öl gefüllt, und ein Wärmeverlust an das darüber im oberen Teil der Ölwanne befindliche Öl, das sich im Stillstand verhältnismäßig rasch abkühlt, ist vermieden.The object of the invention is to prevent this. This consists in in a device for keeping the lubricating oil of internal combustion engines warm the lower part of the oil pan, in which the suction opening of the lubricating oil pump is located located, is enclosed on its outer sides by heat insulating walls, the lower Close off part of the oil pan with a heat insulating wall towards the crankcase and to provide an opening in this which can be shut off by a float. Through this is made possible that that portion of the engine oil that is used when starting the engine is sucked off by the oil pump and fed to the lubrication points, for a possible is kept warm for a long time after the engine has been shut down. the Heat radiation to the crankcase is largely prevented. The lower Part of the oil pan is practically always completely filled with oil, and there is a loss of heat to the oil located above in the upper part of the oil pan, which is at a standstill cools relatively quickly is avoided.

Es sei noch erwähnt, daß es bekannt ist, unterhalb der Ölwanne einen besonderen Ölbehälter vorzusehen, der von der Ölwanne im Abstand angeordnet und daher thermisch isoliert ist. Die bekannten Ölbehälter dieser Art sind aber dem Kühlluftstrom ausgesetzt und haben keinen Schutz gegen das Erkalten des Ölvorrates.It should also be mentioned that it is known to have one below the oil pan Provide a special oil container that is spaced from the oil pan and is therefore thermally insulated. The known oil tanks of this type are the Exposed to the flow of cooling air and have no protection against the oil supply cooling down.

In Ausgestaltung der Erfindung können die Wärmeisolierwände auf der Außenseite der Ölwanne an Scharnieren schwenkbar gelagert sein und mittels eines Seilzuges geschwenkt werden, so daß bei Stillsetzung der Brennkraftmaschine die Wärmeisolierwände vom Fahrersitz aus oder durch einen Thermostaten in diejenige Stellung geschwenkt werden können, in der sie einen völligen Schutz des genannten unteren Teiles des Ölvorrates bewirken.In an embodiment of the invention, the heat insulating walls on the The outside of the oil pan can be pivoted on hinges and by means of a Cable are pivoted so that when the engine is shut down Heat insulating walls from the driver's seat or through a thermostat into that Position can be pivoted, in which they have a complete protection of the said effect lower part of the oil supply.

Ein Ausführungsbeispiel der Erfindung ist nachstehend an Hand einer Zeichnung erläutert. In dieser ist mit 1 der Motor eines Kraftfahrzeuges bezeichnet, an dessen Unterseite eine Ölwanne angebracht ist, die sich aus dem Oberteil 2 und dem Unterteil 3 zusammensetzt. Zwischen den Teilen 2 und 3 ist eine Wärmedämmschicht 4 angebracht, die mit einer Öffnung 5 für den Anschluß der Ölpumpe 6 versehen ist, welche das Öl aus ihrem Sieb 6' ansaugt. Außerdem weist die Isolierschicht 4 einen Durchlaß 7 für das Öl auf. Dieser Durchlaß wird von einem Schwimmer 8 abgeschlossen, um einen Wärmeaustausch zwischen dem Öl im Oberteil 2 und dem Unterteil 3 zu verhindern.An embodiment of the invention is shown below with reference to a Drawing explained. In this, the engine of a motor vehicle is denoted by 1, on the underside of which an oil pan is attached, which consists of the upper part 2 and the lower part 3 composed. Between parts 2 and 3 is a thermal insulation layer 4 attached, which is provided with an opening 5 for the connection of the oil pump 6, which sucks the oil out of its sieve 6 '. In addition, the insulating layer 4 has a Passage 7 for the oil. This passage is closed by a float 8, to prevent heat exchange between the oil in the upper part 2 and the lower part 3.

Zur Wärmeisolierung des Öles im Unterteil 3 sind fernerhin Isolierplatten 9, 10 und 11 vorgesehen, die bei 12 und 13 miteinander gelenkig verbunden sind, damit die Platten 9 und 11 beim Betrieb des Fahrzeuges aus ihrer schützenden Stellung herausgeschwenkt werden können. Dies erfolgt durch einen Seilzug 14, der über Rollen 15 und 15' sowie 16 und 16' geführt ist und vom Fahrerhaus zu betätigen ist.For thermal insulation of the oil in the lower part 3, insulating plates 9, 10 and 11 are also provided, which are hinged to one another at 12 and 13 so that the plates 9 and 11 can be pivoted out of their protective position when the vehicle is in operation. This is done by a cable pull 14, which is guided over rollers 15 and 15 ' and 16 and 16' and can be operated from the driver's cab.
