Abstract

The coolant and/or lubrication circuit, for an internal combustion motor, has a pump which is operated by an electromotor wh is controlled by a value from a constant control action. The pump is operated in relation to a nominal control value, either to stopped at times or simply operated at a lower power rating. A sensor sets the motor speed. The sensor can register wetness at a surface, for a fuel pump, and the adjustment can be to the paddle angle or height at a water pump to set the vol. of coolant impelled into the circuit.

Description

Die Erfindung betrifft eine Kühl- und/oder Schmiermittelfördereinrichtung mit einer von einem Antrieb antreibbaren Pumpe zur Schmierölförderung oder Kühlwasserumwälzung in Brennkraftmaschinen.The invention relates to a coolant and / or lubricant delivery device with one that can be driven by a drive Pump for lubricating oil delivery or cooling water circulation in Internal combustion engines.

Bei Verbrennungsmotoren ist die Pumpe für die Schmierölförderung üblicherweise eine in die Ölwanne integrierte Zahnradpumpe, während die Wasserpumpe an die Außenseite des Motorblocks angebaut ist. Der Antrieb beider Pumpen erfolgt jeweils über eine von der Brennkraftmaschine angetriebene Kette oder einen Keilriemen. Beide Pumpen sind also permanent mit der Brennkraftmaschine verbunden und werden somit während des Betriebs der Brennkraftmaschine kontinuierlich angetrieben, was einen entsprechenden Energieaufwand erfordert.In the case of internal combustion engines, the pump is for the lubricating oil delivery usually one integrated in the oil pan Gear pump while the water pump is on the outside of the Engine blocks is attached. Both pumps are driven each via one driven by the internal combustion engine Chain or a V-belt. So both pumps are permanently connected to the internal combustion engine thus during the operation of the internal combustion engine continuously driven what a corresponding Energy expenditure required.

Aufgabe der Erfindung ist es deshalb, die Schmierung und/oder Kühlwasserumwälzung bei Verbrennungsmotoren energiesparender zu gestalten.The object of the invention is therefore the lubrication and / or cooling water circulation in internal combustion engines to make it more energy-efficient.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Antrieb ein Elektromotor ist, dass ein Fühlglied zum Erzeugen einer Regelgröße in der Brennkraftmaschine vorgesehen ist und dass der Elektromotor in Abhängigkeit von der Regelgröße mittels einer Regelung ansteuerbar ist.This object is achieved in that the An electric motor is driven by a sensing element Generating a controlled variable in the internal combustion engine is provided and that the electric motor is dependent can be controlled by the controlled variable by means of a control.

Abhängig von der Regelgröße können somit derartige Pumpen entweder zeitweise stillgesetzt oder lediglich so betrieben werden, dass sie mit entsprechend verminderter Leistung arbeiten, um vorgegebene Betriebsparameter, wie Kühlwassertemperatur oder einen Mindestöldurchsatz, zu gewährleisten. Ein großer Vorteil wird darin gesehn, dass durch die gezielte Ansteuerung lediglich dann Kühl- und/oder Schmiermittel umgewälzt wird, wenn dies erforderlich ist. Hierdurch wird nicht nur die Einsatzzeit des Kühl- und/oder Schmiermittels verlängert, es wird auch der effektive Wirkungsgrad der Brennkraftmaschine erhöht, da die Pumpen nur bei Bedarf betrieben werden. Die Lebensdauer der Pumpen selbst wird auch erhöht. Ferner können die Pumpen bei langsam laufender Brennkraftmaschine mit hoher oder erhöhter Drehzahl betrieben werden, was unter Umständen zu Kühlzwecken erforderlich ist. Da beim Stand der Technik gewährleistet sein muss, dass auch bei Leerlauf der Brennkraftmaschine eine Mindestmenge an Kühl- und/oder Schmiermittel gefördert werden muss, wurde dies durch eine entsprechend groß dimensionierte Pumpe erreicht, die dann bei schnell laufender Brennkraftmaschine eine zu große Fördermennge aufweist. Bei der erfindungsgemäßen Kühl- und/oder Schmiermittelfördereinrichtung kann die Pumpe deshalb kleiner dimensioniert sein.Depending on the controlled variable, pumps of this type can thus be used either temporarily shut down or only operated as such be that with correspondingly reduced performance work to predetermined operating parameters, such as cooling water temperature or a minimum oil throughput. A great advantage is seen in the fact that the targeted control only then cooling and / or Lubricant is circulated if necessary. As a result, not only the operating time of the cooling and / or Extended lubricant, it also becomes the most effective Efficiency of the internal combustion engine increases as the pumps can only be operated when required. The lifespan of the pumps itself is also increased. Furthermore, the pumps can slow running internal combustion engine with high or increased speed are operated, which under certain circumstances Cooling purposes is required. Because in the state of the art It must be ensured that the Internal combustion engine a minimum amount of cooling and / or Lubricant must be promoted, this was done by a correspondingly large pump reached, then too large for an internal combustion engine running at high speed Has funding. In the cooling and / or Lubricant delivery device can the pump therefore be smaller.

Bevorzugt findet dabei als Pumpenantriebsmotor ein niedervoltbetriebener Gleichstrommotor, insbesondere ein 12 Volt oder ein 24 Volt Motor Verwendung.It is preferably used as a pump drive motor low-voltage DC motor, especially a 12th Volts or a 24 volt motor use.

Sowohl für die Schmierölförderung als auch Motorkühlung ist es dabei günstig, als Fühlglied der Regelung zur Ermittlung der Regelgröße einen Sensor vorzusehen, durch den zur Drehzahlregelung der Pumpe ein Stellglied ansteuerbar ist.For both lubricating oil delivery and engine cooling it is favorable to use it as a sensing element of the regulation the controlled variable to provide a sensor through which to Speed control of the pump, an actuator can be controlled.

Für die Regelung der Schmierölförderung hat sich dabei ein Feuchtesensor als vorteilhaft erwiesen, der zur Feststellung eines ausreichenden Schmierfilmes einer Lauf- oder Lagerfläche der Brennkraftmaschine zuzuordnen ist. Bei einer anderen Ausführungsform ist der Sensor ein Temperatursensor, der reibungsbedingte Temperaturänderungen ermittelt und temperaturabhängige Signate an die Regeleinrichtung übermittelt. Derartige Sensoren sind insbesondere im Bereich von kritischen Lagerflächen, z.B. Kurbellagerschalen, Zylinderlaufbuchsen oder dergleichen vorgesehen.There has been an agreement for the regulation of lubricating oil production Moisture sensor proved to be advantageous for Finding a sufficient lubricating film of a running or Storage area of the internal combustion engine is to be assigned. At In another embodiment, the sensor is on Temperature sensor, the temperature changes due to friction determined and temperature-dependent signatures to the Control device transmitted. Such sensors are especially in the area of critical storage areas, e.g. Crank bearing shells, cylinder liners or the like intended.

Sofern die zur Kühlung oder Schmierung vorgesehenen Pumpe als Flügelzellenpumpe konzipiert ist, kann dabei durch das Stellglied zur Regelung der zu fördernden Flüssigkeit auch die Winkellage oder die Höhe der Pumpenflügel veränderbar sein.If the pump intended for cooling or lubrication is designed as a vane pump, can by Actuator for regulating the liquid to be pumped too the angular position or the height of the pump blades can be changed his.
