Abstract
Description
Die Erfindung betrifft eine Drehzahlsensoranordnung gemäß Oberbegriff von Anspruch 1 sowie die Verwendung der Drehzahlsensoranordnung in Kraftfahrzeugen.The invention relates to a speed sensor arrangement according to the preamble of claim 1 and to the use of the speed sensor arrangement in motor vehicles.
Es sind Drehzahlsensoranordnungen nach dem induktiven Wirkprinzip bekannt, wie beispielsweise in einen Abgasturbolader integriert, beschrieben in Druckschrift
Die Erfindung hat sich die Aufgabe gestellt, eine Drehzahlsensoranordnung mit eigenständiger Energieversorgung vorzuschlagen.The object of the invention has been found to propose a speed sensor arrangement with independent power supply.
Diese Aufgabe wird erfindungsgemäß gelöst durch die Drehzahlsensoranordnung gemäß Anspruch 1.This object is achieved by the speed sensor arrangement according to claim 1.
Der Erfindung liegt insbesondere der Gedanke zu Grunde, ein Spulenelement als Sensorelement zur Erfassung der Drehzahl zu verwenden und dieses Spulenelement auch zusätzlich zur Gewinnung elektrischer Energie gemäß dem induktiven Prinzip zu nutzen und diese elektrische Energie innerhalb der Sensoranordnung zur Energieversorgung zu verwenden.The invention is based in particular on the idea to use a coil element as a sensor element for detecting the rotational speed and also to use this coil element in addition to obtaining electrical energy according to the inductive principle and to use this electrical energy within the sensor arrangement for power supply.
Unter einem magnetischen Encoder wird bevorzugt ein Maschinenelement verstanden, das einen, insbesondere inkrementalen, Winkelmaßstab trägt. Als Encoder können zum einen ferromagnetische Zahnräder oder Lochscheiben dienen, die in Kombination mit einem Permanentmagneten einen veränderlichen magnetischen Luftspalt erzeugen bzw. die magnetische Flussdichte modulieren, zum anderen können es eine permanentmagnetische Encoder sein, die mit der Welle rotieren. Insbesondere können es permanentmagnetische Encoder mit einer ganzzahligen Folge permanent magnetisierter Nord/Südpol-Areale sein, die in alternierender Folge eine zum Kreis geschlossene Encoderspur bilden. Im übertragenen Sinne dient der magnetische Encoder als Impulsgeber innerhalb der Drehzahlsensoranordnung.A magnetic encoder is preferably understood to mean a machine element which carries an angular, in particular incremental, angle. On the one hand, ferromagnetic gears or perforated disks can serve as encoders which, in combination with a permanent magnet, produce a variable magnetic air gap or modulate the magnetic flux density, on the other hand, it can be a permanent magnetic encoder which rotates with the shaft. In particular, they may be permanent magnetic encoders with an integral sequence of permanently magnetized north / south pole areas, which form an encoder track closed in a circle in an alternating sequence. In a figurative sense, the magnetic encoder serves as a pulse generator within the speed sensor arrangement.
Vorzugsweise wird eine elektronische Signalverarbeitungsschaltung des Sensors vom Spulenelement mit elektrischer Energie versorgt.Preferably, an electronic signal processing circuit of the sensor is supplied by the coil element with electrical energy.
Das Spulenelement versorgt bevorzugt ein zusätzliches Sensorelement, wie beispielsweise ein Drucksensorelement, mit elektrischer Energie.The coil element preferably supplies an additional sensor element, such as a pressure sensor element, with electrical energy.
Der Sensor weist zweckmäßigerweise eine Sende- und/oder Empfangseinrichtung zur drahtlosen Signalübertragung auf, welche von dem Spulenelement mit elektrischer Energie versorgt wird. Insbesondere weist der Sensor keinerlei Drahtanbindung zu einer elektronischen Kontrolleinheit auf, welche zumindest die Drehzahl als Information weiterverarbeitet oder weiterleitet. Dies spart Kosten sowie Installationsaufwand ein. Außerdem ist eine Zuverlässigkeit von Drahtverbindungen im Bereich von Turboladern aufgrund der relativ großen Hitzeentwicklung mit relativ großem Materialaufwand erreichbar oder möglicherweise zweifelhaft.The sensor expediently has a transmitting and / or receiving device for wireless signal transmission, which is supplied with electrical energy by the coil element. In particular, the sensor has no wire connection to an electronic control unit, which at least further processes the speed as information or forwards. This saves costs and installation costs. In addition, reliability of wire connections in the field of turbochargers due to the relatively large heat generation with relatively high cost of materials reachable or possibly doubtful.
Der Sensor umfasst bevorzugt eine Energieversorgungskontrolleinheit, welche die vom Spulenelement bereitgestellte elektrische Energie der wenigstens einen weiteren Komponente in definierter Weise zur Verfügung stellt und diese insbesondere aufbereitet, beispielsweise mit einem Tiefpass.The sensor preferably comprises a power supply control unit which provides the electrical energy supplied by the coil element to the at least one further component in a defined manner and processes it in particular, for example with a low-pass filter.
Unter einer weiteren Komponente wird vorzugsweise eine elektronische Signalverarbeitungsschaltung, ein zusätzliches Sensorelement, oder eine Sende- und/oder Empfangseinheit verstanden.A further component is preferably understood to mean an electronic signal processing circuit, an additional sensor element, or a transmitting and / or receiving unit.
Die Welle ist vorzugsweise als Welle eines Turboladers ausgebildet und der magnetische Encoder sowie der Sensor sind dabei im kompressorseitigen Bereich der Welle des Turboladers angeordnet.The shaft is preferably designed as a shaft of a turbocharger and the magnetic encoder and the sensor are arranged in the compressor side region of the shaft of the turbocharger.
Der magnetische Encoder ist dabei bevorzugt als Permanentmagnet ausgebildet, welcher als oder in einer Befestigungsmutter am kompressorseitigen Ende der Turbowelle angeordnet ist, insbesondere als oder in der Befestigungsmutter des Kompressorrades.The magnetic encoder is preferably designed as a permanent magnet, which is arranged as or in a fastening nut on the compressor side end of the turbo shaft, in particular as or in the fastening nut of the compressor wheel.
Alternativ vorzugsweise ist der magnetische Encoder weichmagnetisch ausgebildet, insbesondere dient das Kompressorrad selbst als magnetischer Encoder, der das Magnetfeld eines Permanentmagneten moduliert, der im Sensor angeordnet ist. Dieser Permanentmagnet umfasst dazu besonders bevorzugt einen Polstift, mit welchem das Magnetfeld zumindest teilweise gerichtet wird.Alternatively, preferably, the magnetic encoder is formed soft magnetic, in particular, the compressor wheel itself serves as a magnetic encoder that modulates the magnetic field of a permanent magnet, which is arranged in the sensor. For this purpose, this permanent magnet particularly preferably comprises a pole pin, with which the magnetic field is at least partially directed.
Es ist zweckmäßig, dass der Sensor ein zusätzliches Druck-Sensorelement zur Erfassung des Luftdrucks im Luftauslass des Kompressors umfasst, welches vom Spulenelement mit elektrischer Energie versorgt wird. Insbesondere weisen das Spulenelement bezüglich der Erfassung der Drehzahl der Welle sowie das zusätzliche Druck-Sensorelement eine zumindest teilweise gemeinsame Signalverarbeitungsschaltung auf, die ebenfalls von dem Spulenelement mit elektrischer Energie versorgt wird.It is expedient that the sensor comprises an additional pressure sensor element for detecting the air pressure in the air outlet of the compressor, which is supplied by the coil element with electrical energy. In particular, the coil element with respect to the detection of the rotational speed of the shaft and the additional pressure sensor element on an at least partially common signal processing circuit, which is also supplied by the coil element with electrical energy.
Das Spulenelement ist bevorzugt in Kunststoff gegossen angeordnet.The coil element is preferably arranged in plastic.
Die Erfindung betrifft außerdem die Verwendung der Drehzahlsensoranordnung in Kraftfahrzeugen zur Erfassung der Drehzahl, und insbesondere zusätzlich des Drucks, eines Turboladers. The invention also relates to the use of the speed sensor arrangement in motor vehicles for detecting the rotational speed, and in particular additionally the pressure, of a turbocharger.
