Description
Die Erfindung betrifft einen Winkelsensor zum Erfassen eines Drehwinkels sowie einen Sensoranordnung mit einem solchen Winkelsensor.The invention relates to an angle sensor for detecting an angle of rotation and a sensor arrangement with such an angle sensor.
Die Verwendung eines Winkelsensors zur Erfassung des Höhenstands bzw. des Ein- und Ausfederwegs zwischen Radträger und Karosserie eines Fahrzeugs ist aus dem Stand der Technik bekannt. Dabei leitet eine Anlenkstange die translatorische Bewegung entsprechend des Höhenstands an den Winkelsensor weiter, der die translatorische Bewegung in eine Drehbewegung einer Welle umwandelt. Zur Aufnahme der Bewegung der Anlenkstange ist die Welle mit einem integrierten Hebel ausgebildet. An ihrem unteren Ende weist die Welle gewöhnlicherweise einen Dipolmagnet auf, dessen Drehstellung mittels eines Hallelements erfasst und zu einem Sensorausgangssignal weiterverarbeitet wird. Dabei ist es äußerst wichtig, dass die Welle in dem Sensorgehäuse mit einem sehr geringen radialen und axialen Spiel gelagert ist. Entsprechend erfordern die Lagerung sowie die Abdichtung zwischen Welle und Sensorgehäuse, ggf. unter Zuhilfenahme zusätzlicher Vorrichtungen zur axialen Fixierung der Welle, einen hohen mechanischen und konstruktiven Aufwand.The use of an angle sensor for detecting the level or the deflection and rebound travel between the wheel carrier and body of a vehicle is known from the prior art. A link rod forwards the translatory movement according to the level to the angle sensor, which converts the translatory movement into a rotary movement of a shaft. The shaft is designed with an integrated lever to accommodate the movement of the link rod. At its lower end, the shaft usually has a dipole magnet, the rotational position of which is detected by means of a Hall element and processed further to form a sensor output signal. It is extremely important that the shaft is mounted in the sensor housing with very little radial and axial play. Accordingly, the bearing and the seal between the shaft and the sensor housing, possibly with the aid of additional devices for axially fixing the shaft, require a high level of mechanical and design effort.
Ein solcher Sensor ist beispielsweise aus
Es ist Aufgabe der Erfindung, einen Winkelsensor anzugeben, der unaufwändig und / oder kostengünstig realisiert werden kann.It is an object of the invention to provide an angle sensor which can be implemented in an uncomplicated and / or inexpensive manner.
Die Aufgabe wird gelöst mittels eines Winkelsensors zum Erfassen eines Drehwinkels basierend auf einer relativen Winkellage eines physikalischen Feldes, umfassend eine Anlenkstange zur Übertragung einer Bewegung, eine Gelenkstange zum Aufnehmen der Bewegung der Anlenkstange, wobei die Gelenkstange an einem ersten Stangenende drehbar an der Anlenkstange befestigt ist, ein von der Gelenkstange abragendes Geberelement, ein Gehäuse, aufweisend ein Nehmerelement, wobei das Geber- und das Nehmerelement so ausgebildet sind, dass das physikalische Feld zwischen beiden übertragbar ist.The object is achieved by means of an angle sensor for detecting an angle of rotation based on a relative angular position of a physical field, comprising an articulated rod for transmitting a movement, an articulated rod for receiving the movement of the articulated rod, the articulated rod being rotatably attached to the articulated rod at a first rod end , a transmitter element protruding from the articulated rod, a housing, having a slave element, the transmitter and slave elements being designed such that the physical field can be transmitted between the two.
Bevorzugte Ausführungsformen der Erfindung sind Gegenstand der abhängigen Ansprüche und der Beschreibung. Der Wortlaut der Ansprüche wird durch ausdrückliche Bezugnahme zum Inhalt der Beschreibung gemacht.Preferred embodiments of the invention are the subject of the dependent claims and the description. The wording of the claims is made the content of the description by express reference.
Im Sinne der Erfindung wird unter einem physikalischen Feld vorzugsweise die räumliche Verteilung einer physikalischen Größe verstanden, beispielsweise ein Magnetfeld, ein Elektrisches Feld, ein Temperaturfeld, ein Dichtefeld oder ein Gravitationsfeld. Die relative Winkellage eines physikalischen Feldes ergibt sich vorzugsweise aus der Ausrichtung der räumlichen Verteilung.In the sense of the invention, a physical field is preferably understood to mean the spatial distribution of a physical quantity, for example a magnetic field, an electric field, a temperature field, a density field or a gravitational field. The relative angular position of a physical field preferably results from the alignment of the spatial distribution.
Die Erfindung geht von der Überlegung aus, dass der Bauraum bzw. die Abmessungen im Bereich zwischen einer Fahrzeugkarosserie und einem Radträger und damit die Anbindungspunkte eines Winkelsensors zur Höhenstandserfassung stark variieren können. Entsprechend müssten verschiedene Varianten eines Winkelsensors bereitgestellt werden, die sich in der Länge des Hebels mit dem die Welle in Drehung versetzt wird, unterscheiden. Typischerweise können sich die erforderlichen Hebellängen zwischen 50mm und 100mm unterscheiden und durch diese Variabilität hohe Kosten verursachen. Da erfindungsgemäß jedoch eine einfache Gelenkstange verwendet wird, deren Anpassung an unterschiedliche Anforderungen verschiedener Fahrzeugtypen deutlich einfacher ist, können Kosten gespart werden. Die erforderliche spielarme Lagerung einer Welle wäre somit zwar nicht mehr möglich, jedoch begegnet die Erfindung diesem Problem damit, dass das Geberelement nicht etwa am Ende der Welle angebracht ist, sondern von der Gelenkstange abragt und somit eine von der Drehachse beabstandete, also exzentrische Messung ermöglicht. Die exzentrische Messung bringt dabei mehr Bauraum und flexiblere Möglichkeiten bei der Ausbildung des Geber- und Nehmerelements, gegebenenfalls auch der Auswerteelektronik mit sich. Vor allem kann aber auf die aufwändig zu konstruierende und herzustellende Gehäuse-Welle- bzw. Lager-Welle-Paarung verzichtet werden, was den Einsatz einer gegenüber einem klassischen Hebel deutlich einfacher variierbaren Gelenkstange ermöglicht und somit Kosten spart.The invention is based on the consideration that the installation space or the dimensions in the area between a vehicle body and a wheel carrier and thus the connection points of an angle sensor for height measurement can vary widely. Accordingly, different variants of an angle sensor would have to be provided, which differ in the length of the lever with which the shaft is rotated. Typically, the required lever lengths can differ between 50mm and 100mm and cause high costs due to this variability. However, since a simple articulated rod is used according to the invention, the adaptation to different requirements of different vehicle types is significantly easier, costs can be saved. The required low-play mounting of a shaft would thus no longer be possible, but the invention addresses this problem by the fact that the transmitter element is not attached to the end of the shaft, for example, but rather protrudes from the articulated rod and thus enables an eccentric measurement spaced from the axis of rotation . The eccentric measurement brings with it more installation space and more flexible options when designing the encoder and receiver element, and possibly also the evaluation electronics. Above all, the housing-shaft or bearing-shaft pairing, which is complex to construct and manufacture, can be dispensed with, which enables the use of an articulated rod that is much easier to vary than a classic lever and thus saves costs.
Es ist bevorzugt, dass das Geberelement innerhalb der von den Längsachsen der Gelenkstange und der Anlenkstange beziehungsweise deren Mittelachsen aufgespannten Ebene von der Gelenkstange abragt. In dieser Ebene übersetzen die beiden Stangen vorzugsweise die lineare Höhenbewegung in eine Drehbewegung bei der die Anlenk- und die Gelenkstange in Relation zu ihrer gemeinsamen Drehachse am ersten Stangenende stets in unterschiedliche Richtungen drehen. Diese Drehbewegung lässt sich besonders einfach dadurch wiedergeben, dass das Geberelement in dieser Ebene von der Gelenkstange abragt.It is preferred that the transmitter element projects from the articulated rod within the plane spanned by the longitudinal axes of the articulated rod and the articulated rod or their central axes. In this plane, the two rods preferably translate the linear height movement into a rotary movement in which the articulation and the articulated rod always rotate in different directions in relation to their common axis of rotation at the first rod end. This rotary movement can be reproduced particularly easily by the fact that the transmitter element protrudes from the articulated rod in this plane.
Nach einer bevorzugten Ausführungsform weist das Gehäuse ein auf der Gehäuseaußenseite hervorstehendes, insbesondere kugelförmiges, Lagerelement auf, wobei die Gelenkstange mit einer korrespondierenden Ausnehmung am zweiten Stangenende drehbar an dem Lagerelement gelagert ist. Durch das auf der Gehäuseaußenseite angeordnete Lagerelement ist es einerseits möglich, Elektronik in dem Gehäuse hermetisch abzudichten, da das Gehäuse keine Öffnung benötigt. Andererseits entfällt bezüglich der Konstruktion und Bereitstellung der Lagerung ein Großteil auf das Gehäuse mit dem Lagerelement, so dass die Gelenkstange lediglich eine korrespondierende Ausnehmung aufweisen muss. Die Gelenkstange kann also sehr einfach ausgeführt werden, so dass eine Bereitstellung verschieden langer Gelenkstangen für unterschiedliche Fahrzeugtypen kaum Kosten verursacht.According to a preferred embodiment, the housing has a, in particular spherical, bearing element protruding on the outside of the housing, the articulated rod being rotatably mounted on the bearing element with a corresponding recess on the second rod end. The bearing element arranged on the outside of the housing makes it possible, on the one hand, to hermetically seal electronics in the housing, since that Housing no opening needed. On the other hand, with regard to the construction and provision of the bearing, a large part of the housing with the bearing element is used, so that the joint rod only has to have a corresponding recess. The articulated rod can therefore be made very simple, so that providing differently long articulated rods for different types of vehicles hardly incurs any costs.
Es ist bevorzugt, dass das Geberelement vollständig außerhalb des Gehäuses angeordnet ist. Somit sind alle drehbaren beziehungsweise beweglichen Teile des Winkelsensors außerhalb des Gehäuses angeordnet und auf eine Dichtung kann verzichtet werden.It is preferred that the transmitter element is arranged completely outside the housing. All rotatable or movable parts of the angle sensor are thus arranged outside the housing and a seal can be dispensed with.
Vorzugsweise umschließt das Gehäuse das Nehmerelement, insbesondere vollständig. Das Nehmerelement ist damit vor Schmutz, Feuchtigkeit und anderen äußeren Einflüssen geschützt.The housing preferably encloses the slave element, in particular completely. The slave element is thus protected from dirt, moisture and other external influences.
Es ist bevorzugt, dass das Nehmerelement und / oder das Geberelement eine Grundform in Form eines Kreissegments oder eines Segments eines Kreisrings aufweist. Da das Geberelement in Folge der Drehung der Gelenkstange ebenfalls eine Drehbewegung macht, sorgt eine solche Grundform dafür, dass eine effiziente Überdeckung des Nehmerelements durch das Geberelement erfolgen kann.It is preferred that the slave element and / or the transmitter element have a basic shape in the form of a segment of a circle or a segment of a circular ring. Since the encoder element also rotates as a result of the rotation of the articulated rod, such a basic shape ensures that the slave element can be efficiently covered by the encoder element.
Es entspricht einer bevorzugten Ausführungsform, dass der Winkelsensor als induktiver Winkelsensor ausgebildet ist. Dies ermöglicht eine berührungsfreie, unaufwändige Messung.It corresponds to a preferred embodiment that the angle sensor is designed as an inductive angle sensor. This enables a contact-free, uncomplicated measurement.
Vorzugsweise weist das Nehmerelement eine mit einer Wechselspannung beaufschlagte Erregerspule und mindestens eine mit der Erregerspule induktiv gekoppelte Empfangsspule auf, wobei das Geberelement so angeordnet und ausgebildet ist, insbesondere leitfähig und / oder ferromagnetisch, dass die induktive Kopplung durch die Position des Geberelements beeinflusst wird. Bevorzugt erstreckt sich das Nehmerelement beziehungsweise erstreckt sich die Empfangsspule entlang eines Kreissegments oder eines Segments eines Kreisrings. Es ist weiterhin bevorzugt, dass zwei Empfangsspulen vorhanden sind, wobei jede Empfangsspule eine Wicklung mit einem periodischen Verlauf aufweist, wobei diese periodischen Verläufe zwischen den Empfangsspulen phasenverschoben sind.The slave element preferably has an excitation coil to which an AC voltage is applied and at least one receiving coil inductively coupled to the excitation coil, the transmitter element being arranged and designed, in particular conductive and / or ferromagnetic, such that the inductive coupling is influenced by the position of the transmitter element. The receiving element preferably extends or the receiving coil extends along a segment of a circle or a segment of an annulus. It is further preferred that there are two receiving coils, each receiving coil having a winding with a periodic course, these periodic courses between the receiving coils being out of phase.
Es entspricht einer alternativen bevorzugten Ausführungsform, dass der Winkelsensor als Magnetfeldsensor ausgebildet ist, beispielsweise basierend auf einem galvanomagnetischen, magneto-resistiven oder magneto-optischen Effekt, wobei vorzugsweise das Nehmerelement als magnetfeldsensierendes Element und das Geberelement als Permanentmagnet ausgebildet ist.It corresponds to an alternative preferred embodiment that the angle sensor is designed as a magnetic field sensor, for example based on a galvanomagnetic, magneto-resistive or magneto-optical effect, the slave element preferably being designed as a magnetic field-sensing element and the transmitter element as a permanent magnet.
Gemäß einem weiteren Aspekt der Erfindung weist eine Sensoranordnung einen Winkelsensor nach einer zuvor genannten Ausführungsform auf, wobei das Gehäuse des Winkelsensors an einer Fahrzeugkarosserie, insbesondere im Bereich der Stoßdämpferaufhängung eines Rades, drehbar gelagert ist und die Anlenkstange an einem Teil des Fahrwerks, insbesondere einem Querlenker oder Stabilisator drehbar gelagert ist.According to a further aspect of the invention, a sensor arrangement has an angle sensor according to a previously mentioned embodiment, the housing of the angle sensor being rotatably mounted on a vehicle body, in particular in the area of the shock absorber suspension of a wheel, and the linkage rod on a part of the chassis, in particular a control arm or stabilizer is rotatably mounted.
