Description
Die
Erfindung bezieht sich auf einen Drehschwingungsdämpfer gemäß dem Oberbegriff
des Patentanspruches 1. Ein solcher Drehschwingungsdämpfer ist
aus der
Drehschwingungsdämpfer werden zur Dämpfung von Drehschwingungen einer Welle verwendet, wie z. B. der Kurbelwelle oder Nockenwelle einer Kolbenkraftmaschine. Ein mögliches Ausführungsbeispiel eines Drehschwingungsdämpfers hat ein mit der Welle verbundenes Gehäuse, das eine geschlossene ringförmige Aufnahmekammer aufweist, in der ein Schwungring und eine hochviskose Flüssigkeit angeordnet sind, wobei der Schwungring über elastische Elemente mit dem Gehäuse gekoppelt ist.Become torsional vibration damper for damping used by torsional vibrations of a shaft, such as. B. the crankshaft or camshaft of a reciprocating internal combustion engine. A possible embodiment a torsional vibration damper Has a housing connected to the shaft, which is a closed annular Containing receiving chamber in which a flywheel and a highly viscous liquid are arranged, with the flywheel over elastic elements with the housing is coupled.
Zur Überwachung des Schwingungsverhaltens ist es erforderlich, bestimmte Parameter der einzelnen Elemente des Drehschwingungsdämpfers zu messen.For monitoring the vibration behavior requires certain parameters to measure the individual elements of the torsional vibration damper.
Die
Bei Drehschwingungsdämpfern können, insbesondere wenn als Dämpfungsmedium eine Flüssigkeit verwendet wird, kritische Temperaturen auftreten, so daß es wünschenswert ist, auch die Temperatur des Drehschwingungsdämpfers zu überwachen. Hierzu ist es nach internem Stand der Technik der Anmelderin bekannt, im rotierenden Gehäuse des Drehschwingungsdämpfers einen Temperatursensor anzubringen, dessen elektrische Signale durch Schleifringe am Gehäuse abgegriffen werden. Die Verwendung von Schleifringen ist problematisch, da die Lebensdauer der Schleifringe begrenzt ist und durch Verschmutzung, Verschleiß, ungleichmäßige Andruckkräfte von Schleiferfedern etc. die Signalübertragung störanfällig ist und ein hohes Signalrauschen auftritt.at torsional vibration dampers can, especially when as a damping medium a liquid is used, critical temperatures occur, making it desirable is also to monitor the temperature of the torsional vibration damper. For this it is after Known in the art of the applicant, in rotating Housing of torsional vibration damper to install a temperature sensor whose electrical signals through Slip rings on the housing be tapped. The use of slip rings is problematic because the life of the slip rings is limited and due to pollution, Wear, uneven pressure forces of Grinder springs etc. the signal transmission is prone to failure and high signal noise occurs.
Aufgabe der Erfindung ist es daher, den Drehschwingungsdämpfer dahingehend zu verbessern, daß seine Temperatur frei von Störeinflüssen verschleißarm erfaßt werden kann.task The invention therefore is to improve the torsional vibration damper, that his Temperature free of interference can be detected wear can.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is achieved by the features specified in claim 1 solved. Advantageous embodiments and further developments of the invention are the dependent claims refer to.
Die Grundidee der Erfindung liegt darin, die Signalübertragung des am oder im sich drehenden Gehäuse angeordneten Temperatursensors drahtlos durchzuführen. Hierzu wird vorzugsweise das in anderem Zusammenhang bekannte RFID-Verfahren eingesetzt. Das RFID (Radiofrequenz-Identifikation) arbeitet mit einem sogenannten Transponder, der aufgrund externer elektromagnetischer Anregung durch ein Lesegerät das elektromagnetische Anregungsfeld des Lesegerätes verändert und somit codierte Signale überträgt. Auf dem Markt sind inzwischen sogenannte RFID-Chips erhältlich, die komplexere Funktionen durchführen können und insbesondere auch längere Datensätze übertragen. Die Energieversorgung der Transponder erfolgt bei einigen Bauarten über die empfangenen Funkwellen, die über eine Induktionsspule einen Kondensator aufladen, der die Energieversorgung des RFID-Chips übernimmt.The The basic idea of the invention lies in the signal transmission of the am or in itself rotating housing arranged to perform wireless temperature sensor. This is preferably done used the RFID method known in another context. The RFID (radio frequency identification) works with a so-called Transponder due to external electromagnetic excitation by a reader changes the electromagnetic excitation field of the reader and thus transmits coded signals. On the market is now available as so-called RFID chips, perform the more complex functions can and especially longer ones Transfer records. The energy supply of the transponder takes place on some types of the received radio waves over An induction coil will charge a capacitor that supplies the power of the RFID chip takes over.
Nach einer vorteilhaften Weiterbildung der Erfindung werden sogenannte SAW-Tags als Transponder verwendet, die auf dem SAW-Effekt (surface acoustic wave) basieren. Hierbei werden akustische Oberflächenwellen verwendet. Das Lesegerät sendet elektromagnetische Wellen aus, die auf einen Schallwandler, wie z. B. einen Piezo-Kristall, auftreffen und in akustische Oberflächenwellen umgewandelt werden. Diese werden dann von mehreren auf einem Substrat aufgebrachten Reflektoren zurückgeworfen und über den Wandler und eine Antenne nach außen wieder als elektromagnetische Welle abgegeben. Der wesentliche Vorteil der SAW-Tags liegt in ei ner hohen Temperaturfestigkeit, einer relativ großen Lesedistanz sowie einer mechanischen und chemischen Robustheit. Damit kann das Lesegerät relativ weit entfernt von dem heißen Gehäuse angeordnet werden, dessen Temperatur gemessen werden soll.To An advantageous development of the invention are so-called SAW tags are used as transponders based on the SAW effect (surface acoustic wave). Here, surface acoustic waves are used. The reader sends electromagnetic Waves off, on a sound transducer, such. B. a piezo-crystal, and be converted into surface acoustic waves. These are then applied by several on a substrate Reflectors thrown back and over Converter and an antenna outward again as electromagnetic Wave delivered. The main advantage of the SAW tags is in a high Temperature resistance, a relatively long reading distance and a mechanical and chemical robustness. This allows the reader relatively far away from the hot casing can be arranged, whose temperature is to be measured.
Da die Temperaturmessung nicht hochdynamisch erfolgen muß, da sich die Temperatur des Drehschwingungsdämpfers nur relativ langsam ändert, genügt eine Temperaturmessung alle ein bis zwei Minuten. Damit ist es auch möglich, nur einen Temperatursensor und nur eine Induktionsspule an einer singulären Stelle des Gehäuses anzubringen, die nur einmal pro Umdrehung am Lesegerät vorbeiläuft.There the temperature measurement does not have to be highly dynamic, since the temperature of the torsional vibration damper changes only relatively slowly, is sufficient Temperature measurement every one to two minutes. This is also possible, only a temperature sensor and only one induction coil at a singular location of the housing which passes only once per revolution on the reader.
