Stand der TechnikState of the art
Die
Erfindung geht aus von einer Vorrichtung zur Messung eines Winkels
eines drehbaren Körpers nach der Gattung des unabhängigen
Anspruchs. Eine gattungsgemäße Vorrichtung ist
bereits aus der
Es ist Aufgabe der Erfindung, einen gewissen Koaxialversatz der Welle innerhalb des Sensoraufbaus zu kompensieren. Diese Aufgabe wird gelöst durch die Merkmale des unabhängigen Anspruchs.It Object of the invention, a certain coaxial displacement of the shaft within the sensor assembly. This task will solved by the features of the independent claim.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorrichtung zur Messung eines Winkels eines drehbaren Körpers mit den Merkmales des unabhängigen Anspruchs hat demgegenüber den Vorteil, einen Koaxialversatz zwischen drehbarem Körper, beispielsweise einer Welle, und Antriebsrad im Sensor zu kompensieren. Bei der gefundenen Lösung steigt auch das Antriebsmoment des Sensors nicht an. Auch eine starre Kopplung zwischen Mitnehmerwelle und Antriebsrad der Signalgeber wird so ermöglicht. Außerdem werden auch keine Winkelfehler erzeugt. Dies wird insbesondere durch eine quasi fliegende Lagerung der Mittel zum koaxialen Versatzausgleich erreicht.The Inventive device for measuring a Angle of a rotatable body with the characteristics of the independent Claim has the advantage over a coaxial offset between a rotatable body, such as a shaft, and To compensate drive wheel in the sensor. At the found solution The drive torque of the sensor does not increase. Also a rigid one Coupling between drive shaft and drive wheel of the signal transmitter is made possible. In addition, no angle errors generated. This is especially due to a quasi-flying storage reaches the means for coaxial offset compensation.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass die Mittel zum koaxialen Versatzausgleich eine Lagerung insbesondere in zwei Richtungen quer zur Drehachse des drehbaren Körpers zulassen. Hierzu ist beispielsweise eine Taumelscheibe vorgesehen, die gegenüber dem Antriebsrad einerseits und gegenüber einer Adapterscheibe andererseits jeweils in einer Richtung beweglich gelagert ist. Dadurch wird bei einer Drehung der Welle durch ein Taumeln um die Mittellinie sämtlicher Koaxialversatz zwischen Mitnehmerwelle und Antriebsrad des Sensors ohne Winkelfehler ausgeglichen. Durch dieses Konzept ist es möglich, dass das Antriebsrad im Gehäuse des Sensors fest gelagert werden kann, während Taumel- und Adapterscheibe praktisch fliegend gelagert sind. Weiterhin kann die Mitnehmerwelle als Beispiel für einen drehbaren Körper mit der Adapterscheibe fest verbunden werden.In an expedient development is provided that the means for coaxial offset compensation storage in particular in two directions transverse to the axis of rotation of the rotatable body allow. For this example, a swash plate is provided, the opposite to the drive wheel on the one hand and opposite an adapter disk on the other hand in each case movable in one direction is stored. This is due to a rotation of the shaft by a tumble around the center line all coaxial offset between drive shaft and drive wheel of the sensor balanced without angle error. By this concept, it is possible that the drive wheel in Housing of the sensor can be stored firmly while Tumble and adapter disc are mounted practically flying. Farther can the driver shaft as an example of a rotatable Body firmly connected to the adapter disc.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass der Adapter vorzugsweise ring- bzw. rohrförmig ausgeführt ist, wobei im mittleren Bereich ein radial nach außen stehender Flansch vorgesehen ist. Dadurch wird es leicht möglich, dass der Adapter auf der Oberseite der Taumelscheibe aufsitzt, so dass eine Begrenzung der Bewegung in axialer Richtung erfolgt.In an expedient development is provided that the adapter is preferably designed annular or tubular is, wherein in the central region a radially outward standing Flange is provided. This makes it easy that the adapter is seated on the top of the swash plate, so that a limitation of the movement takes place in the axial direction.
In einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der als Mittel zum Ausgleich eines koaxialen Versatzes wirkende zumindest eine Adapter mit dem die Welle verbunden ist. Hierbei ist es besonders vorteilhaft, wenn der Adapter in die Welle integriert ist oder der Adapter als Teil der Welle ausgebildet ist. Durch die Integration der Funktion des Adapters direkt in die Welle, bei einem Lenksystem also direkt in die Lenkwelle, wird erreicht, dass sich die Anzahl der Scheiben des Hubs reduziert. Diese Reduktion der Anzahl der Bauteile erlaubt vorteilhafterweise einen höheren Grad der Miniaturisierung.In an advantageous embodiment of the invention is provided that acting as a means for compensating a coaxial offset at least one adapter with which the shaft is connected. in this connection It is particularly advantageous if the adapter is integrated into the shaft or the adapter is formed as part of the shaft. By the Integration of the function of the adapter directly into the shaft, with a Steering system so directly into the steering shaft, that is achieved reduces the number of discs of the hub. This reduction of Number of components advantageously allows a higher Degree of miniaturization.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass der Adapter mit zumindest einer Nase oder Aussparung versehen ist, die mit einer Aussparung oder Nase in der Taumelscheibe zusammenwirkt. Hierdurch wird ein axialer Versatz quer zur Drehrichtung in einer definierten Richtung gezielt ermöglicht.In an expedient development is provided that the adapter provided with at least one nose or recess is, which interacts with a recess or nose in the swash plate. As a result, an axial offset transversely to the direction of rotation in a targeted direction allows targeted.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass die Taumelscheibe zumindest eine Ausnehmung oder einen Überstand aufweist, welche/r mit einem Überstand oder einer Ausnehmung des Antriebsrads zusammenwirkt. Somit wird ein Versatz in Richtung quer zur Rotationsachse des drehbaren Körpers in definierter Weise ermöglicht. Das so gewählte Nut-Feder-Prinzip ermöglicht eine Bewegungsfreiheit in je eine definierte Richtung.In an expedient development is provided that the swash plate at least one recess or a supernatant having which with a supernatant or a recess of the Drive wheel cooperates. Thus, an offset becomes transverse to the axis of rotation of the rotatable body in a defined Way allows. The chosen tongue and groove principle allows freedom of movement in each one defined Direction.
Vorzugsweise sind die Richtungen der Bewegungsfreiheit zwischen Taumelscheibe und Adapter sowie zwischen Taumelscheibe und Antriebsrad um vorzugsweise 90° versetzt.Preferably are the directions of freedom of movement between swash plate and adapter and between the swash plate and the drive wheel to preferably 90 ° offset.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass der Außendurchmesser des Adapters so gewählt ist, dass ein Versatzausgleich im Inneren des Antriebsrads möglich ist.In an expedient development is provided that the outer diameter of the adapter is chosen so is that an offset compensation inside the drive wheel possible is.
Weitere zweckmäßige Weiterbildungen ergeben sich aus weiteren abhängigen Ansprüchen und aus der Beschreibung.Further expedient developments emerge from further dependent claims and the description.
