Abstract

A linear motor is housed within a drive wheel. The inner non-rotating part (1) of the wheel is secured to the vehicle, the electrical field windings (3) being around its edge. The outer rotatable tyre (4) has a magnetic core (5) around its inside, held at a spacing of several mm from the inner non-rotating part via spacing rollers (6). A varying magnetic field is obtained between the non-rotating part and the tyre for provoking the forward rotation of the latter. Pref., the winding voltage is calculated via an in-board computer for varying the velocity and drive torque. USE - Propulsion of road vehicle, bicycle or invalid carriage.

Description

Beschreibung der KonstruktionDescription of the construction

Elektroantrieb zur Gegenstandsbeförderung durch einen im Antriebsrad eingebauten Linearmotor.Electric drive for the transportation of objects by a Linear motor built into the drive wheel.

Jetziger Stand der TechnikCurrent state of the art

Alle bisher zur Beförderung von Gegenständen eingesetzten Räder (bei Autos, Motorräder, Elektrorollstühle, Fahrräder usw.) werden bei Benutzung von Elektroantrieben von der Mitte der Achse des Rades angetrieben.All previously used for the transportation of objects Wheels (for cars, motorcycles, electric wheelchairs, bicycles etc.) are used by the Driven center of the axle of the wheel.

Bei einer Magnetbahn erfolgt der Antrieb durch ein wanderndes und gesteuertes Magnetfeld zwischen Fahrzeug und Schienenstrecke und wird von diesem nach vorne gezogen.In the case of a magnetic track, the drive takes place through a moving and controlled magnetic field between vehicle and rail track and is forward from this drawn.

Kritik des Standes der TechnikCritique of the state of the art

Durch die Antriebsart von der Achse des Rades ist in der Regel ein Getriebe und Motorblock notwendig. Bei einem Antrieb mit einem Elektromotor wird daher ein Teil der Energie in den mechanischen Antrieb verbraucht. Außerdem ist eine kleine, raumsparende Bauart kaum möglich. Due to the drive type of the axle of the wheel is in the Usually a gearbox and engine block are necessary. At a Drive with an electric motor therefore becomes part of the Energy consumed in the mechanical drive. Furthermore a small, space-saving design is hardly possible.  

Lösung der AufgabeSolution of the task

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß wie bei einer Magnetbahn der Antrieb durch ein wanderndes Magnetfeldes zwischen Fahrzeug und Schiene direkt in ein Rad umgesetzt wird.The object is achieved in that how in the case of a magnetic track, the drive by a moving one Magnetic field between vehicle and rail directly in one Wheel is implemented.

Dazu bleibt der innere Teil des Rades (1) nicht drehbar mit dem anzutreibenden Gegenstand (2) (Auto, Rollstuhl, Fahrrad usw.) fest verbunden.For this purpose, the inner part of the wheel ( 1 ) remains non-rotatably connected to the object ( 2 ) to be driven (car, wheelchair, bicycle, etc.).

Im dem Rand des inneren Teiles werden die elektrischen Feldwicklungen (3) untergebracht.The electrical field windings ( 3 ) are accommodated in the edge of the inner part.

Der äußere drehbare Reifen (4) mit seinem Magnetkern (5) wird durch Abstandsrollen (6) auf millimetergenauen Abstand zum inneren Teil (1) des Rades gehalten.The outer rotatable tire ( 4 ) with its magnetic core ( 5 ) is held at a millimeter-precise distance from the inner part ( 1 ) of the wheel by spacer rollers ( 6 ).

Dadurch kann der Aufbau eines magnetischen Feldes zwischen dem feststehenden inneren Teil (1) und dem beweglichen äußeren Reifen (4) mit seinem Magnetkern erzeugt werden und durch das gesteuerte Wandern des Magnetfeldes eine Vorwärtsbewegung des äußeren Reifen (4) erreicht werden, da der innere Teil des Rades (1) mit dem festverbundenen Aufbau (2) durch die Schwerkraft und eines weiteren abstützenden Rades (7) ein Abheben bzw. Überdrehen verhindern.As a result, the build-up of a magnetic field between the fixed inner part ( 1 ) and the movable outer tire ( 4 ) with its magnetic core can be generated, and a forward movement of the outer tire ( 4 ) can be achieved by the controlled migration of the magnetic field, since the inner part prevent the wheel ( 1 ) from being lifted or overturned by the force of gravity and another supporting wheel ( 7 ) with the firmly attached structure ( 2 ).

Durch einen Computer kann die Spannung geregelt werden und auch unterschiedlichste Feldpakete angesteuert werden um eine Veränderung der Geschwindigkeit und auch die der Anzugsleistung zu erreichen.The voltage can be regulated and controlled by a computer A wide variety of field packets can also be controlled a change in speed and also that of Achieve tightening performance.

Als Stromquelle können Batterien, Solarzellen oder Strom durch Stromabnehmer aus einer Oberleitung Verwendung finden.Batteries, solar cells or electricity can be used as the power source by using pantographs from an overhead line Find.

Bei Verwendung mindestens zwei dieser Antriebsräder bei einem Fahrzeug werden beide Räder synchron über einen Computer gesteuert.When using at least two of these drive wheels in a vehicle, both wheels are synchronized controlled a computer.

Bei Verwendung dieser Antriebsräder für ein Fahrzeug kann der feststehende Aufbau zusätzlich mit einem oder mehreren in sich drehbar gelagerten Rädern unterstützt werden.When using these drive wheels for a vehicle can the fixed structure additionally with or supports several rotatably mounted wheels will.

Der Größe der Antriebsräder steht nichts im Wege, so daß sogar im inneren Bereich des nicht drehbaren Teiles des Rades bereits Stromquellen wie Batterien untergebracht werden können. Nothing stands in the way of the size of the drive wheels, so that even inside the non-rotatable part of the Rades already housed power sources such as batteries can be.  

Erzielbare VorteileAchievable advantages

Durch dieses linearangetriebene Rad sind neue Möglichkeiten im gesamten Antrieb von unterschiedlichsten Fahrzeugen gegeben.This linearly driven wheel opens up new opportunities in the entire drive of different vehicles given.

Bei einem Elektrorollstuhl könnten die Batterien bereits im Rad mit eingebaut werden und so eine kompaktere Bau­ weise zulassen.The batteries could already be in an electric wheelchair be built into the wheel and thus a more compact construction allow wisely.

Bei einem Elektroauto können die Antriebsräder so groß gestaltet werden, daß der gesamte Batterietrog in bzw. zwischen den Antriebsrädern gebaut werden kann. Durch Wegfall des ganzen Getriebes und Motorblocks könnte die gesamte Länge bei einer Vierpersonenfahrgastkabine erheblich verkürzt werden, durch die Lenkung mittels Abbremsung oder Beschleunigung eines Rades läßt sich der Wendekreis auf die Diagonale des Fahrzeugs beschränken und das Fahrzeug wäre somit im innerstädtischen Verkehr erheblich wendiger.In an electric car, the drive wheels can be so big be designed so that the entire battery tray in or can be built between the drive wheels. By Elimination of the entire transmission and engine block could entire length in a four-passenger cabin be significantly shortened by means of steering Braking or acceleration of a wheel can be Limit the turning circle to the diagonal of the vehicle and the vehicle would be in inner city traffic considerably more agile.

Bei einem Fahrrad könnte das Vorderrad mit einem solar­ betriebenen Antriebsrad ausgerüstet werden.For a bike, the front wheel could be solar driven drive wheel can be equipped.
