Description
Die Erfindung betrifft eine Übertragungseinrichtung mit einem induktiven Übertrager und eine Radnabeneinheit mit der Übertragungseinrichtung.The The invention relates to a transmission device with an inductive transformer and a hub unit with the transmission device.
Beispielsweise
aus der
Mit der vorausgehend beschriebenen Vorrichtung ist ein unterbrechungsfreies Übertragen möglich, wobei bei Anbringung eines der ringartigen Transformatorkerne auf einem Mantel einer Welle je nach Wellendurchmesser vergleichsweise große und damit kostenintensive ringartige Transformatorkerne erforderlich sind. Weiterhin ist oftmals an einem Wellenende, an dem prinzipiell ringartige Transformatorkerne kleinen Durchmessers eingesetzt werden könnten, der dafür erforderliche Einbauraum aufgrund konstruktiver Vorgaben nicht verfügbar.With the device described above, an uninterrupted transmission is possible, wherein when mounting one of the ring-like transformer cores on one Sheath of a shaft depending on the shaft diameter comparatively large and thus costly ring-shaped transformer cores are required. Furthermore, often at a shaft end, on the principle ring-like Transformer cores of small diameter could be used, the required for this Installation space not available due to design specifications.
Eine Aufgabe der Erfindung ist es, eine Übertragungseinrichtung zum Übertragen von Energie und zusätzlich von Informationen zwischen zwei zueinander drehbaren Elementen zu schaffen, so dass bei hinreichender Funktionserfüllung, im Hinblick auf Energie- und Datenübertragung, die Übertragungseinrichtung einfach und damit kostengünstig ausgestaltet ist.A The object of the invention is a transmission device for transmitting of energy and additionally information between two mutually rotatable elements so that, with sufficient functional performance, in terms of energy efficiency, and data transmission, the transmission device simple and therefore inexpensive is designed.
Die Aufgabe wird durch den Gegenstand des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The The object is solved by the subject matter of patent claim 1. advantageous Embodiments are described in the subclaims.
Gemäß Anspruch 1 beinhaltet eine Übertragungseinrichtung mit einem induktiven Übertrager folgende Merkmale:
- – Der Übertrager ist wenigstens zweigeteilt ausgebildet,
- – ein Teil des Übertragers ist an einem Element angeordnet und ein weiterer Teil des Übertragers ist an einem weiteren Element angeordnet, wobei wenigstens eines der Elemente gegenüber dem anderen drehbar ist, und
- – die Teile sind derart ausgebildet und an den Elementen angeordnet, dass im Laufe einer Umdrehung eine induktive Kopplung zwischen den Teilen bestimmungsgemäß variiert und wenigstens einmal ein Maximum erreicht.
- The transmitter is at least two-part,
- A part of the transformer is arranged on one element and another part of the transformer is arranged on a further element, at least one of the elements being rotatable relative to the other, and
- - The parts are designed and arranged on the elements that in the course of a revolution, an inductive coupling between the parts varies as intended and at least once reaches a maximum.
Die Erfindung beruht dabei auf der Erkenntnis, dass für viele Anwendungen die Möglichkeit, Energie und Daten zwischen zwei zueinander drehbaren Elementen zeitkontinuierlich ohne Unterbrechungen übertragen zu können, gar nicht erforderlich ist, sondern ein Übertragen von Zeitpunkt zu Zeitpunkt mit dazwischenliegenden Pausenabschnitten vollkommen ausreichend ist. Dies trifft insbesondere auf zwischen einem sich drehenden und einem sich nicht drehenden Teil einer Radnabeneinheit zu übertragende Energie und Daten zu, bei denen im ruhenden Zustand kein Übertragen gefordert ist. Gegenüber den eingangs beschriebenen Lösungen werden durch die Lösung gemäß Anspruch 1 unter anderem die Vorteile erzielt, dass der Einfluss auf die mechanische Konstruktion des Gesamtsystems weitaus geringer ist, dass eine höhere mechanische Robustheit erzielt wird und dass durch die kompakte Bauweise der mechanische Aufwand, einschließlich für Montage und Service geringer ist, womit auch Kostenvorteile einhergehen.The The invention is based on the recognition that for many Applications the possibility Energy and data between two mutually rotatable elements time-continuous transmitted without interruptions to be able to is not necessary, but a transfer from time to Time with intermediate pause sections perfectly adequate is. This is especially true between a spinning one and a non-rotating part of a hub unit to be transmitted Energy and data too, where in the dormant state no transfer is required. Compared to the initially described solutions be through the solution according to claim 1 among other things, the advantages that the influence on the mechanical construction of the overall system is much lower, that a higher one mechanical robustness is achieved and that by the compact Construction of the mechanical effort, including for assembly and service lower is, with which also cost advantages go hand in hand.
Weiterhin werden durch die Lösung gemäß Anspruch 1 gegenüber vergleichbaren Lösungen mittels einer Batterie oder ähnlichem deren Nachteile verhindert, beispielsweise eine eingeschränkte Lebensdauer der Batterie, die Empfindlichkeit der Batterie hinsichtlich der Temperatur und/oder Vibrationen und eine begrenzte Kapazität der Batterie, so dass nur eine begrenzte Anzahl von Sensoren mit ein und derselben Batterie versorgbar sind und nur eine langsame Update-Rate der Sensoren möglich ist. Weiterhin stellt die Übertragung von Daten nach dem transformatorischen Prinzip gegenüber anderen drahtlosen Datenübertragungsmethoden eine gegenüber Störungen überaus unanfällige Methode dar.Farther be through the solution according to claim 1 opposite comparable solutions by means of a battery or similar their disadvantages prevented, for example, a limited life the battery, the sensitivity of the battery in terms of Temperature and / or vibration and a limited capacity of the battery, leaving only a limited number of sensors with one and the same Battery are available and only a slow update rate of the sensors possible is. Furthermore, the transmission stops of data according to the transformative principle over other wireless Data Transfer Methods one opposite Disturbances exceedingly unanfällige method dar.
