Description
Die Erfindung betrifft ein Magnetfeld erzeugendes Element zur Befestigung eines Kompressorrades an einer Turbowelle eines Abgasturboladers, mit einem Grundkörper, der einen ringförmigen, mit einer Turbowelle rotierenden Magneten aufnimmt.The invention relates to a magnetic field generating element for fastening a compressor wheel to a turbo shaft of an exhaust gas turbocharger, comprising a base body which receives an annular, rotating with a turbo shaft magnet.
Die von einer Brennkraftmaschine erzeugte Leistung hängt von der Luftmasse und der Kraftstoffmenge ab, die der Brennkraftmaschine zugeführt werden kann. Zur Leistungssteigerung ist es notwendig, der Brennkraftmaschine mehr Verbrennungsluft und Kraftstoff zuzuführen. Diese Leistungssteigerung wird bei einem Saugmotor durch eine Hubraumvergrößerung oder durch die Erhöhung der Drehzahl erreicht. Eine Hubraumvergrößerung führt aber grundsätzlich zu schwereren, in den Abmessungen größeren und damit teureren Brennkraftmaschinen. Die Steigerung der Drehzahl bringt besonders bei größeren Brennkraftmaschinen erhebliche Probleme und Nachteile mit sich.The power generated by an internal combustion engine depends on the air mass and the amount of fuel that can be supplied to the internal combustion engine. To increase the power, it is necessary to supply the internal combustion engine more combustion air and fuel. This increase in performance is achieved in a naturally aspirated engine by increasing the displacement or by increasing the speed. However, an increase in displacement generally leads to heavier, larger in size and therefore more expensive internal combustion engines. The increase in the speed brings significant problems and disadvantages, especially for larger internal combustion engines.
Eine viel genutzte technische Lösung zur Steigerung der Leistung einer Brennkraftmaschine ist die Aufladung. Damit bezeichnet man die Vorverdichtung der Verbrennungsluft durch einen Abgasturbolader oder auch mittels eines vom Motor mechanisch angetriebenen Verdichters. Ein Abgasturbolader besteht im Wesentlichen aus einem Verdichter und einer Turbine, die mit einer gemeinsamen Welle verbunden sind und mit der gleichen Drehzahl rotieren. Die Turbine setzt die normalerweise nutzlos verpuffende Energie des Abgases in Rotationsenergie um und treibt den Verdichter an. Der Verdichter, der in diesem Zusammenhang auch als Kompressor bezeichnet wird, saugt Frischluft an und fördert die vorverdichtete Luft zu den einzelnen Zylindern des Motors. Der größeren Luftmenge in den Zylindern kann eine erhöhte Kraftstoffmenge zugeführt werden, wodurch die Verbrennungskraftmaschine mehr Leistung abgibt. Der Verbrennungsvorgang wird zudem günstig beeinflusst, so dass die Verbrennungskraftmaschine einen besseren Gesamtwirkungsgrad erzielt. Darüber hinaus kann der Drehmomentverlauf einer mit einem Turbolader aufgeladenen Brennkraftmaschine äußerst günstig gestaltet werden.A much-used technical solution for increasing the performance of an internal combustion engine is the charging. This refers to the pre-compression of the combustion air through an exhaust gas turbocharger or by means of a mechanically driven by the engine compressor. An exhaust gas turbocharger consists essentially of a compressor and a turbine, which are connected to a common shaft and rotate at the same speed. The turbine converts the normally useless exhaust energy of the exhaust into rotational energy and drives the compressor. The compressor, which is also referred to as a compressor in this context, draws in fresh air and promotes the pre-compressed air to the individual cylinders of the engine. The larger amount of air in the cylinders can be fed an increased amount of fuel, whereby the internal combustion engine gives more power. The combustion process is also favorably influenced, so that the internal combustion engine achieves a better overall efficiency. In addition, the torque curve of a charged with a turbocharger internal combustion engine can be made extremely low.
Bei zunehmender Abgasmenge kann die maximal zulässige Drehzahl der Kombination aus dem Turbinenrad, dem Kompressorrad und der Turbowelle, die auch als Laufzeug des Abgasturboladers bezeichnet wird, überschritten werden. Bei einer unzulässigen Überschreitung der Drehzahl des Laufzeuges würde dieses zerstört werden, was einem Totalschaden des Turboladers gleichkäme. Gerade moderne und kleine Turbolader mit deutlich kleineren Turbinen- und Kompressorraddurchmessern, die durch ein erheblich kleineres Massenträgheitsmoment ein verbessertes Drehbeschleunigungsverhalten aufweisen, werden vom Problem der Überschreitung der zulässigen Höchstdrehzahl betroffen. Je nach Auslegung des Turboladers führt schon eine Überschreitung der Drehzahlgrenze um etwa 5% zur kompletten Zerstörung des Turboladers.With increasing exhaust gas amount, the maximum allowable speed of the combination of the turbine wheel, the compressor wheel and the turbo shaft, which is also referred to as a running gear of the exhaust gas turbocharger, are exceeded. In an inadmissible exceeding the speed of the running gear this would be destroyed, which would amount to a total loss of the turbocharger. Especially modern and small turbochargers with significantly smaller turbine and Kompressorraddurchmessern, which have a significantly lower moment of inertia improved spin performance are affected by the problem of exceeding the maximum permissible speed. Depending on the design of the turbocharger, exceeding the speed limit by approximately 5% already leads to complete destruction of the turbocharger.

Die Aufgabe der vorliegenden Erfindung ist es daher, ein Magnetfeld erzeugendes Element zur Befestigung eines Kompressorrades an einer Turbowelle eines Abgasturboladers anzugeben, bei dem der Magnet vor mechanischen und chemischen Belastungen geschützt ist.The object of the present invention is therefore to provide a magnetic field generating element for fastening a compressor wheel to a Specify turbo shaft of an exhaust gas turbocharger, in which the magnet is protected from mechanical and chemical stress.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des unabhängigen Anspruchs 1 gelöst.This object is achieved by the features of
Dadurch, dass das Magnetfeld erzeugende Element mindestens dreiteilig, aus einem Mantelkörper, dem Grundkörper und dem ringförmigen Magneten aufgebaut ist, wobei der Grundkörper aus einem das Magnetfeld gut leitenden, hochfesten Metall besteht, auf dem der ringförmige Magnet gelagert ist und der Mantelkörper aus einem nichtmagnetischen Material besteht, und mit dem Grundkörper derart verschweißt ist, dass der Mantelkörper und der Grundkörper für den Magneten eine Einfassung bilden, können hohe Anzugsdrehmomente auf das Magnetfeld erzeugende Element übertragen werden, womit das Kompressorrad sicher an der Turbowelle befestigt werden kann. Das Anzugdrehmoment wird von dem Mantelkörper direkt auf den Grundkörper übertragen und der Magnet wird mechanisch nicht beansprucht. Der hochfeste Grundkörper bildet eine gute Verbindung zur Turbowelle und leitet das vom Magnet erzeugte Magnetfeld zum Sensor. Der Mantelkörper bildet zusammen mit dem Grundkörper eine hermetisch gasdichte Einfassung. Hierdurch wird das Eindringen chemisch reaktiver Gase in die Einfassung verhindert und der Magnet wird nachhaltig vor Korrosion geschützt. Die erfindungsgemäße mindestens dreiteilige Ausbildung des Magnetfeld erzeugenden Elementes ermöglicht es, sowohl deren mechanische als auch deren magnetischen Eigenschaften optimal zu gestalten.Characterized in that the magnetic field generating element is at least three-part, composed of a shell body, the base body and the annular magnet, wherein the base body of a magnetic good conducting, high-strength metal, on which the annular magnet is mounted and the shell body of a non-magnetic Material exists, and is welded to the base body so that the sheath body and the base body for the magnet form a border, high tightening torques can be transmitted to the magnetic field generating element, so that the compressor can be securely attached to the turbo shaft. The tightening torque is transmitted from the shell body directly to the body and the magnet is not mechanically stressed. The high-strength body forms a good connection to the turbo shaft and passes the magnetic field generated by the magnet to the sensor. The jacket body together with the base body forms a hermetically gas-tight enclosure. This prevents the penetration of chemically reactive gases into the enclosure and the magnet is sustainably protected against corrosion. The inventive at least three-part design of the magnetic field generating element makes it possible to make both their mechanical and their magnetic properties optimal.
Bei einer Ausgestaltung ist in dem Grundkörper ein Gewinde zur Verschraubung des Magnetfeld erzeugenden Elementes mit einem Gewinde auf der Turbowelle ausgebildet. Der Grundkörper aus hochfestem Metall kann besonders feine Gewinde aufnehmen, wodurch das Kompressorrad mit einer großen Kraft gegen die Turbowelle verschraubt werden kann. Dabei ist es vorteilhaft, wenn der Grundkörper aus 17-4PH Stahl (auch bekannt als 1.4542 oder 1.4548 Stahl) besteht. Dieser Stahl leitet das Manetfeld sehr gut und lässt sich gut schweißen. Die Festigkeit dieses Stahls ist extrem hoch.In one embodiment, a thread for screwing the magnetic field generating element is formed with a thread on the turbo shaft in the body. The base body made of high-strength metal can accommodate particularly fine threads, whereby the compressor wheel can be screwed with a large force against the turbo shaft. It is advantageous if the base body made of 17-4PH steel (also known as 1.4542 or 1.4548 steel) exists. This steel guides the manet field very well and is easy to weld. The strength of this steel is extremely high.
Bei einer Weiterbildung enthält der ringförmige Magnet Selteneerden-Metalle. Selteneerden-Magnete wie zum Beispiel NdFeB- oder SmCo-Magnete erzeugen ein relativ hohes magnetisches Feld, was auch von einem relativ weit entfernten Sensor noch gut detektiert werden kann.In a further development, the annular magnet contains rare earth metals. Rare earth magnets such as NdFeB or SmCo magnets produce a relatively high magnetic field, which can still be detected well by a relatively distant sensor.
Bei einer Ausgestaltung besteht der Mantelkörper aus VA-Stahl (zum Beispiel 1.4301 Stahl). Dieser Stahl lässt sich gut mit dem Material des Grundkörpers verschweißen, wobei der Mantelkörper mit geringem Aufwand geometrisch ausgestaltet werden kann, so dass er zur Aufnahme eines Drehwerkzeuges dienen kann.In one embodiment, the shell body made of VA steel (for example, 1.4301 steel). This steel can be welded well with the material of the base body, wherein the sheath body can be geometrically designed with little effort, so that it can serve to receive a turning tool.
