Abstract
Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Regelung eines Schmierölstroms gemäß dem Oberbegriff der Ansprüche 1 bzw. 18, insbesondere zur Schmierung eines Getriebes.The invention relates to a device and a method for controlling a lubricating oil flow according to the preamble of
Getriebe, wie beispielsweise Getriebe von Kraftfahrzeugen, müssen geschmiert werden. Zu diesem Zweck werden nicht selten Regelölpumpen verwendet, das heißt Schmierölpumpen mit einer pumpeninternen Mengenregelung, bei denen zum Beispiel ein Druckanstieg auf der Druckseite der Pumpe zu einer Anpassung der Fördermenge der Pumpe führt. Dort, wo die Fördermenge der Schmierölpumpe darüber hinaus in Abhängigkeit von der Temperatur des Schmieröls gesteuert oder geregelt werden soll, werden bisher zumeist elektronische Steuergeräte eingesetzt, denen von einem oder mehreren Temperatursensoren zur Messung der Schmieröltemperatur Temperatursignale zugeführt werden, wie zum Beispiel in der
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren der eingangs genannten Art dahingehend zu verbessern, dass sie es ohne die Notwendigkeit einer externen Stromversorgung bzw. von Sensoren ermöglichen, die Fördermenge der Schmierölpumpe in Abhängigkeit von der Schmieröltemperatur zu regeln.Proceeding from this, the present invention seeks to improve a device and a method of the type mentioned in that they allow it without the need for an external power supply or sensors to control the flow rate of the lubricating oil pump in dependence on the lubricating oil temperature.
Diese Aufgabe wird bei der erfindungsgemäßen Vorrichtung durch ein Dehnstoffelement gelöst, das auf ein Stellglied der Schmierölpumpe einwirkt, während bei dem erfindungsgemäßen Verfahren die Fördermenge der Schmierölpumpe durch eine Volumenänderung eines Dehnstoffelements verändert wird.This object is achieved in the apparatus according to the invention by an expansion element, which acts on an actuator of the lubricating oil pump, while in the inventive method, the delivery rate of the lubricating oil pump is changed by a change in volume of a Dehnstoffelements.
Der Erfindung liegt der Gedanke zugrunde, die temperaturabhängige Regelung der Fördermenge der Schmierölpumpe mit Hilfe eines Dehnstoffelements vorzunehmen. Dies ermöglicht mit einfachen Mitteln eine selbsttätige Veränderung der Fördermenge der Schmierölpumpe in Abhängigkeit von der Schmieröltemperatur, ohne die Notwendigkeit von Temperatursensoren und von einer Energiezufuhr abhängigen Steuer- bzw. Regeleinrichtungen.The invention is based on the idea to make the temperature-dependent control of the flow rate of the lubricating oil pump with the aid of a Dehnstoffelements. This allows by simple means an automatic change in the delivery rate of the lubricating oil pump as a function of the lubricating oil temperature, without the need of temperature sensors and dependent on an energy supply control or regulating devices.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass das Dehnstoffelement das Stellglied bewegt und dadurch die Fördermenge der Schmierölpumpe erhöht, wenn die Temperatur des Schmieröls einen vorgegebenen Temperaturschwellenwert übersteigt. Dies ermöglicht es, einen Anstieg der Schmieröltemperatur zu dämpfen, da die höhere Fördermenge der Schmierölpumpe zu einem größere Volumenstrom des Schmieröls und damit zu einer geringeren Erwärmung des Schmieröls führt.A preferred embodiment of the invention provides that the expansion element moves the actuator and thereby increases the delivery rate of the lubricating oil pump when the temperature of the lubricating oil exceeds a predetermined temperature threshold. This makes it possible to damp an increase in the lubricating oil temperature, since the higher flow rate of the lubricating oil pump leads to a larger volume flow of the lubricating oil and thus to a lower heating of the lubricating oil.
Um bei sinkenden Schmieröltemperaturen für eine Rückstellung des Stellgliedes zu sorgen, ist vorteilhaft vorgesehen, dass das Dehnstoffelement das Stellglied entgegen der Kraft einer Rückstellfeder bewegt.In order to ensure a return of the actuator at decreasing lubricating oil temperatures, it is advantageously provided that the expansion element moves the actuator against the force of a return spring.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, das Dehnstoffelement nicht nur als Aktuator oder Regler zur Verstellung der Fördermenge der Schmierölpumpe zu verwenden, sondern auch noch als Ventilglied eines zweckmäßig in die Schmierölpumpe integrierten Thermostat- oder Bypassventils, mit dem je nach Schmieröltemperatur ein mehr oder weniger großer Teil des von der Schmierölpumpe geförderten Schmieröls durch einen dem Getriebe vorgeschalteten Ölkühler gefördert werden kann. Dadurch lässt sich ein eventueller Anstieg der Schmieröltemperatur ebenfalls begrenzen.A further preferred embodiment of the invention provides to use the expansion element not only as an actuator or regulator for adjusting the flow rate of the lubricating oil pump, but also as a valve member of an appropriately integrated in the lubricating oil pump thermostatic or bypass valve, with the depending on the lubricating oil temperature a more or Less large part of the oil pumped by the lubricating oil pump can be promoted by an oil cooler upstream of the transmission. This also limits any increase in the lubricating oil temperature.
In dem zuletzt genannten Fall ist das Dehnstoffelement zweckmäßigerweise so angeordnet, dass bei steigender Schmieröltemperatur zuerst ein Teil des Schmieröls durch den Ölkühler geleitet wird, sobald die Schmieröltemperatur einen ersten vorgegebenen Temperaturschwellenwert übersteigt, und dass dann zusätzlich die Fördermenge der Schmierölpumpe gesteigert wird, wenn die Schmieröltemperatur einen zweiten vorgegebenen Temperaturschwellenwert übersteigt, der höher als der erste Temperaturschwellenwert ist. Zwischen den beiden vorgegebenen Temperaturschwellenwerten wird die Menge bzw. das Volumen des durch den Ölkühler geleiteten Schmieröls zweckmäßig mit steigender Schmieröltemperatur gesteigert.In the latter case, the expansion element is suitably arranged so that with increasing lubricating oil temperature, a portion of the lubricating oil is passed through the oil cooler as soon as the lubricating oil temperature exceeds a first predetermined temperature threshold, and then additionally the delivery rate of the lubricating oil pump is increased when the lubricating oil temperature exceeds a second predetermined temperature threshold which is higher than the first temperature threshold. Between the two predetermined temperature threshold values, the amount or the volume of lubricating oil conducted through the oil cooler is expediently increased with increasing lubricating oil temperature.
Um es zu ermöglichen, das Dehnstoffelement zugleich als Ventilglied des Thermostat- oder Bypassventils und als Aktuator oder Regler zum Verstellen der Fördermenge der Schmierölpumpe zu verwenden, sieht eine weitere vorteilhafte Ausgestaltung der Erfindung vor, dass das Dehnstoffelement zwischen der Rückstellfeder und einer Stützfeder angeordnet ist, deren Federkennlinie flacher als die Federkennlinie der Rückstellfeder ist, so dass das Dehnstoffelement das Stellglied entgegen der Kraft der Rückstellfeder erst dann bewegt, wenn die Stützfeder um ein vorbestimmtes Maß zusammengedrückt worden ist. Mit anderen Worten verformt sich bei Schmieröltemperaturen unterhalb von dem zweiten vorgegebenen Temperaturschwellenwert nur die Stützfeder, während sich bei Schmieröltemperaturen oberhalb von dem zweiten vorgegebenen Temperaturschwellenwert nur die Rückstellfeder verformt.In order to make it possible to use the expansion element at the same time as a valve member of the thermostatic or bypass valve and as an actuator or regulator for adjusting the flow rate of the lubricating oil pump, provides a further advantageous embodiment of the invention, that the expansion element is disposed between the return spring and a support spring, whose spring characteristic is shallower than the spring characteristic of the return spring, so that the expansion element moves the actuator against the force of the return spring only when the support spring has been compressed by a predetermined amount. In other words, only the support spring deforms at lubricating oil temperatures below the second predetermined temperature threshold value, while only the return spring deforms at lubricating oil temperatures above the second predetermined temperature threshold value.
Als Dehnstoffelement wird zweckmäßig ein Dehnstoffelement verwendet, wie es in Thermostatventilen bereits eingesetzt wird. Zweckmäßig umfasst das Dehnstoffelement einen mit Wachs gefüllten Zylinder, der sich auf der Stützfeder abstützt, und einen aus dem Zylinder ragenden Stift, der auf das Stellglied der Schmierölpumpe einwirkt und der in Abhängigkeit von der Temperatur des Schmieröls mehr oder weniger weit aus dem Zylinder ausgefahren wird. Um für ein schnelles Ansprechen des Dehnstoffelements zu sorgen, wird dieses zweckmäßig von dem von der Schmierölpumpe geförderten Schmieröl umströmt.As expansion element expediently an expansion element is used, as it is already used in thermostatic valves. expedient The expansion element comprises a cylinder filled with wax, which is supported on the support spring, and a protruding from the cylinder pin, which acts on the actuator of the lubricating oil pump and is extended in response to the temperature of the lubricating oil more or less far out of the cylinder. In order to ensure a rapid response of the expansion element, this is suitably flows around the pumped by the lubricating oil pump lubricating oil.
Die Schmierölpumpe ist zweckmäßig eine Flügelzellenpumpe mit variabler Fördermenge, deren Stellglied ein verschwenkbarer Pumpenstellring ist, auf den das Dehnstoffelement direkt oder über einen Hebelmechanismus mechanisch einwirkt. Alternativ können jedoch auch andere Schmierölpumpen mit variabler Fördermenge verwendet werden. Das Dehnstoffelement ist zweckmäßig tangential zum Pumpenstellring und zu dessen Schwenkachse ausgerichtet, während die Rückstellfeder und die Stützfeder zweckmäßig als Schraubendruckfedern ausgebildet sind, deren Längsachsen mit der Längsachse des Dehnstoffelements fluchten.The lubricating oil pump is expediently a vane pump with variable delivery, whose actuator is a pivotable pump collar, which acts on the expansion element directly or mechanically via a lever mechanism. Alternatively, however, other variable displacement lubricating oil pumps may be used. The expansion element is suitably aligned tangentially to the pump collar and the pivot axis, while the return spring and the support spring are suitably designed as helical compression springs whose longitudinal axes are aligned with the longitudinal axis of the expansion element.
Im Folgenden wird die Erfindung anhand von zwei in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:In the following the invention will be explained in more detail with reference to two embodiments shown in the drawing. Show it:
