Description

1. Allgemeines1. General

Im Bereich Elektromobilität bestehen verschiedene Patente zur induktiven Übertragung von elektrischer Energie zum Betrieb und zur Aufladung von Stromspeichern, dabei ist der Wirkungsgrad dieser Spulenanordnungen auf Grund eines großen Luftspaltes zwischen Primär und Sekundärwicklung nach Stand der Technik unbefriedigend.In the field of electromobility, there are various patents for inductive transmission of electrical energy for operation and charging of power storage, while the efficiency of these coil assemblies due to a large air gap between the primary and secondary windings of the prior art is unsatisfactory.

Die hier beschriebene System Niveaurad ermöglicht 1. einen sicheren Betrieb der Energieübertragung sowohl im Stand von Elektrofahrzeugen als auch während der Fahrt der Fahrzeuge und stellt somit eine technische Weiterentwicklung ua. des Patents DE 4236 286 A1 dar. Ziel der hier beschriebenen Erfindung soll die Übertragung von elektrischer Energie auf sich bewegende Fahrzeuge mit hohem Wirkungsgrad sein, dies ist möglich in dem der Abstand einer Induktionsspule (Primärspule) welche in die Fahrbahn eingelassen ist, zu der Spule (Sekundärspule) die am Fahrzeug vorhanden ist, konstant und gering gehalten werden kann. Mit dieser Erfindung ist dabei die Schutz der am Fahrzeug angebrachten Spule auch bei Bodenunebenheiten gewährleistet.The system level wheel described here allows 1. a safe operation of the energy transfer both in the state of electric vehicles and during the journey of the vehicles and thus represents a technical development, among others. of the patent DE 4236 286 A1 The aim of the invention described here is to be the transmission of electrical energy to moving vehicles with high efficiency, this is possible in which the distance of an induction coil (primary coil) which is embedded in the roadway, to the coil (secondary coil) on the vehicle exists, can be kept constant and low. With this invention, the protection of the coil mounted on the vehicle is ensured even with uneven floors.

Gemäß der Erfindung wird eine Sekundärspule mit flexiblen Anschlussleitungen in einem abschwenkbaren Rad so montiert das die Lage der Spule stets waagerecht ausgerichtet ist. Berührt das Rad die Fahrbahn bzw. den Boden so ergibt sich ein definierter Abstand von Sekundärspule zu einer in den Boden eingelassenen Primärspule. Das abschwenkbare Rad wird nur gegen die Fahrbahn, bzw. gegen die in den Boden eingelassene Induktionsspule gedrückt wenn ein Sensor dafür das Signal gibt. Sollte eine Fahrbahnunebenheit überfahren werden so kann die Sekundärspule nicht beschädigt werden, weil immer der Abstand Lauffläche des abschwenkbaren Rades zu Primärspule konstant ist. Der Abstand ist einstellbar.According to the invention, a secondary coil is mounted with flexible connection cables in a swing-wheel so that the position of the coil is always aligned horizontally. If the wheel touches the roadway or the ground, the result is a defined distance from the secondary coil to a primary coil let into the ground. The swing-away wheel is only pressed against the roadway or against the induction coil embedded in the ground when a sensor gives the signal. If a road surface unevenness be run over so the secondary coil can not be damaged because always the distance running surface of the swing-wheel to primary coil is constant. The distance is adjustable.

2. Ausführung2nd execution

Niveaurad besteht aus einer rechten (1) und linken Radscheibe (2) zwischen denen eine Spulenanordnung (Sekundärspule) (10) vorhanden ist. Jedoch kann das Niveaurad auch aus nur einer Radscheibe bestehen, sodass die Spulenanordnung auch neben einer Radscheibe angeordnet ist. Die ganze Anordnung wird von einer Befestigungskonstruktion (4) am Fahrzeug gehalten. Die Radscheiben werden dabei von einer mit der Radstütze verbundene Achse (7) gehalten. Das Niveaurad wird mit einer Radstütze (5) an das zu versorgende Fahrzeug befestigt, wobei durch Knickung der Radstütze mittels Schwenkgelenk und Antrieb (6) die beiden Radscheiben mit der zwischen diesen angeordneten Induktionsspule (10) in Richtung Fahrbahn (3) bewegt werden. Somit werden die Radscheiben gegen die Fahrbahn gedrückt, gleichzeitig werden die Federelemente (8) gespannt. Die Induktionsspule (10) wird durch einen Positionierantrieb (9) mit Hilfe von 2 Führungselementen (11) positioniert, damit ist diese immer waagerecht, also parallel zur Fahrbahn ausgerichtet, so das der Abstand zur Fahrbahn (3) bzw. den darin eingelassenen Fahrbahninduktor stets minimal ist. Dies ist auch der Fall wenn sich die Radscheiben drehen, also sich das Fahrzeug bewegt. Zur Steuerung von Rad und Spulen ist ein Positioniersensor (12) und ein Fahrbahnsensor (14) vorhanden. Wenn das Fahrzeug normalerweise auf der Fahrbahn gefahren wird und keine induktive Energieübertragung erfolgen soll, sind die Radscheiben nach oben abgeknickt. Kommt nun das Fahrzeug in die Nähe des Fahrbahnsensors (14), so wird dessen Identifikationssignal den Antrieb Schwenkgelenk (6) einschalten, sodass die Radscheiben gegen die Fahrbahn gefahren werden damit Induktorspule und Fahrbahnspule mit geringsten Luftspalt zueinander ausgerichtet sind. Ein Positionssensor (12) in der Radkonstruktion wird dann nach Überfahren des Fahrbahninduktors (14) ein Steuersignal zum Wiedereinknicken von Schwenkgelenk mit Radstütze abgeben. Weitere Positionssensoren (12) dienen der Überwachung der Fahrzone und steuern bei grossen Hindernissen Positionierantrieb (9) oder den Antrieb für Schwenkgelenk mit Radstütze so, das diesen Hindernissen zum Schutz der Radkonstruktion ausgewichen wird.Level wheel consists of a right ( 1 ) and left wheel disc ( 2 ) between which a coil arrangement (secondary coil) ( 10 ) is available. However, the level wheel can also consist of only one wheel disc, so that the coil assembly is also arranged next to a wheel disc. The whole arrangement is made of a mounting structure ( 4 ) held on the vehicle. The wheel discs are thereby connected by an axle connected to the wheel support ( 7 ) held. The level wheel is equipped with a wheel support ( 5 ) attached to the vehicle to be supplied, wherein by buckling of the wheel support by means of pivoting joint and drive ( 6 ) the two wheel discs with the induction coil arranged between them ( 10 ) in the direction of the road ( 3 ) are moved. Thus, the wheel discs are pressed against the road, at the same time the spring elements ( 8th ) curious; excited. The induction coil ( 10 ) is controlled by a positioning drive ( 9 ) by means of 2 guide elements ( 11 ), so that this is always horizontal, so aligned parallel to the road, so that the distance to the road ( 3 ) or embedded therein Fahrbahninduktor is always minimal. This is also the case when the wheel discs rotate, so the vehicle is moving. For the control of wheel and coils is a positioning sensor ( 12 ) and a roadway sensor ( 14 ) available. If the vehicle is normally driven on the road and no inductive energy transfer is to take place, the wheel discs are bent upwards. Now comes the vehicle in the vicinity of the road sensor ( 14 ), its identification signal is the drive swivel joint ( 6 ) turn on, so that the wheel discs are driven against the road so that inductor coil and lane coil are aligned with the smallest air gap to each other. A position sensor ( 12 ) in the wheel construction is then after passing the Fahrbahninduktors ( 14 ) emit a control signal for re-nodding of swivel joint with wheel support. Other position sensors ( 12 ) are used to monitor the driving zone and to control the positioning of large obstacles ( 9 ) or the drive for swivel joint with wheel support so that these obstacles are avoided to protect the wheel structure.
