Description

Die Erfindung bezieht sich auf ein auf einer ferromagnetischen Leittrasse bewegbar geführtes, rollbares Modell-Spielfahrzeug, beispielsweise Modell-Eisenbahnfahrzeug oder Modell-Automobil, mit zumindest einem an dessen Unterseite mit Abstand über der Leittrasse angebrachten Dauermagneten.The invention relates to a rollable model toy vehicle, such as a model railway vehicle or model automobile, which is movably guided on a ferromagnetic guide line, with at least one permanent magnet attached to its underside at a distance above the guide line.

Ein Modell-Fahrzeug dieser Art ist beispielsweise in der DE-GM 1 806 055 beschrieben. Hierbei wird unter einem Eisenbahnfahrzeug ein Dauermagnet angebracht, der den Eisenbahnwagen entgleisungssicher auf sein Gleis pressen soll.A model vehicle of this type is described for example in DE-GM 1 806 055. In this case, a permanent magnet is attached under a railway vehicle, which is intended to press the railway wagon onto its track to prevent it from derailing.

In der Zeitschrift "HOBBY", 1966, Nr. 24, Seiten 78/79, ist eine Modellbahn-Lokomotive beschrieben, zwischen deren Rädern an beiden Seiten des Fahrgestells zwei kleine Permanent-Magnete angebracht sind, die über die Vorder-und Hinterräder und durch das Schienenstück zwischen den zwei Auflagepunkten ein geschlossenes Kraftfeld erzeugen. Dadurch soll der Auflagedruck der Räder auf die Schienen verstärkt und die Reibung entsprechend erhöht werden. Hierbei verläuft das Magnetfeld parallel zur Leittrasse.In the magazine "HOBBY", 1966, No. 24, pages 78/79, a model railroad locomotive is described, between the wheels of which two small permanent magnets are attached on both sides of the chassis, which pass over the front and rear wheels and through the rail section between the two support points generate a closed force field. This should increase the contact pressure of the wheels on the rails and increase the friction accordingly. The magnetic field runs parallel to the control route.

Die bei den beiden vorstehend erwähnten Modell-Fahrzeugen eingesetzten Permanent-Magnete zur Erreichung der dort jeweils gesetzten Ziele verleihen den Fahrzeugen ein plumpes und für Modellbahn-Liebhaber abstoßendes Aussehen. Sie sind daher nicht geeignet, die Kipp- und Laufstabilität oder die Reibschlüssigkeit der Antriebsräder eines Modell-fahrzeugs zu verbessern, ohne daß hierdurch gleichzeitig dessen äußeres Erscheinungsbild, das ja dem Original der Großtechnik möglichst nahekommen soll, nicht erheblich zu seinem Nachteil verändert würde.The permanent magnets used in the two model vehicles mentioned above to achieve the goals set there give the vehicles a clumsy and repulsive appearance for model railroad enthusiasts. They are therefore not suitable to improve the tipping and running stability or the frictional engagement of the drive wheels of a model vehicle without thereby not significantly changing its external appearance, which is supposed to come as close as possible to the original of large-scale technology.

Ferner wird durch die zusätzlich am Modell-Fahrzeug angebrachten Permanent-Magnete der erwähnten Art das Gesamtgewicht der Modell-Fahrzeuge nicht unwesentlich erhöht, was wiederum zu einer erhöhten Reibung der Fahrzeuglager führt, die ohnedies schon durch die gewollte Anziehung zwischen Fahrzeugrad und Leittrasse infolge der Magnetwirkung stärker belastet sind.Furthermore, the total ge The importance of the model vehicles is not insignificantly increased, which in turn leads to increased friction in the vehicle bearings, which are already subject to greater stress as a result of the magnetic attraction due to the desired attraction between the vehicle wheel and the guide line.

Außerdem ist das Gehäuse bzw. die Karosserie eines Modell-Fahrzeugs mit relativ hohem Gewicht erfahrungsgemäß wesentlich stärker der Gefahr ausgesetzt, bei einem Stoß oder einem Fall von der Modellbahnplatte auf den Boden infolge der Wirkung hoher Massenkräfte zu zerbrechen.In addition, experience has shown that the housing or body of a model vehicle with a relatively high weight is much more exposed to the risk of breaking from the model railroad plate on the ground as a result of the action of high inertial forces.

Es ist daher Aufgabe der Erfindung, ein Modell-Fahrzeug der eingangs genannten Art zu schaffen, das sich im Verkehr auf seiner Leittrasse stets kippstabil verhält und dessen Antriebsräder es auch bei größeren Trassensteigungen möglichst schlupffrei auf seiner Leittrasse fortbewegen kann, wobei das äußere Erscheinungsbild des Modell-Fahrzeugs in keiner Weise durch störende Fremdkörper beeinträchtigt, das Gesamtgewicht des Modell-Fahrzeugs möglichst klein gehalten und damit dessen Nutzvolumen zugunsten möglicher anderer Nutzlasten, wie Elektronik, Inneneinrichtung od. dgl., möglichst groß sein sollen.It is therefore an object of the invention to provide a model vehicle of the type mentioned that always behaves tilt-stable in traffic on its guideway and whose drive wheels can move on its guideway as slip-free as possible, even on larger inclines, the external appearance of the model -Vehicle in no way affected by disturbing foreign bodies, the total weight of the model vehicle should be kept as small as possible and thus its usable volume should be as large as possible in favor of possible other payloads, such as electronics, interior fittings or the like.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der/die Dauermagnet(e) in/an unterhalb des Modell-Spielfahrzeugs angeordneten Teilen von fahrzeugspezifischen Nachbildungen, wie beispielsweise Fahrzeugzubehör und/oder Rädern und/oder Fahr- bzw. Drehgestellen unauffällig angeordnet sind oder selbst diese Nachbildungen bilden. Ein so beschaffenes Modell-Spielfahrzeug haftet nicht nur kippstabil an seiner Leittrasse, sondern bietet seinen Antriebsrädern auch eine schlupffreie Haftung auf der Leittrasse, so daß das erfindungsgemäße Modell-Spielfahrzeug selbst extreme Trassensteigungen problemlos überwinden kann.This object is achieved according to the invention in that the permanent magnet (s) are arranged in / on parts of vehicle-specific replicas arranged below the model toy vehicle, such as vehicle accessories and / or wheels and / or bogies or bogies, or form these replicas themselves. A model toy vehicle constructed in this way not only sticks to its guideway in a stable manner, but also offers its drive wheels slip-free adhesion on the guideway, so that the model toy vehicle according to the invention can even overcome extreme inclines without problems.

Gemäß der Erfindung werden Seltene-Erden-Kobalt-Magnete als Dauermagnete verwendet, von denen sich Kobalt-Samarium Magnete als besonders vorteilhaft erweisen. Letztere ermöglichen es dem Modell-Fahrzeug, Trassensteigungen von mehr als 100% problemlos zu bewältigen. Die extrem hohe magnetische Kraft, die selbst winzige Magnete aus diesem Material ausüben können, lassen beispielsweise zwischen einer Schiene und einem Antriebsrad einer mit Kobalt-Samarium-Magneten ausgerüsteten Modell-Lokomotive praktisch keinerlei Schlupf zu. Eine mit winzig kleinen Magneten dieser Art versehene Modell-Lokomotive kann sogar kopfüber an einem Gleis hängend auf diesem fahrend sich fortbewegen.According to the invention, rare earth cobalt magnets used as permanent magnets, of which cobalt samarium magnets prove to be particularly advantageous. The latter make it possible for the model vehicle to easily master line gradients of more than 100%. The extremely high magnetic force that even tiny magnets made of this material can exert, for example, practically no slip between a rail and a drive wheel of a model locomotive equipped with cobalt samarium magnets. A model locomotive provided with tiny magnets of this kind can even move upside down on a track while traveling.

Die trotz ihrer großen magnetischen Wirkung sehr kleinen . Abmessungen von Kobalt-Samarium-Magneten lassen es zu, sie in Teilen der Unterkonstruktion von Modell-Fahrzeugen, z.B. in Ölkühlern, an oder in den Drehgestellen von oder in Gerätekästen unter den Modell-D-Zugwagen, in Druckbehältern od. dgl., für den außenstehenden Betrachter praktisch unsichtbar anzubringen, wobei sie knapp über der Fahrschiene aus ferromagnetischem Material positioniert sein müssen, um ihre volle Magnetwirkung optimal ausüben zu können. Vollens unsichtbar wären die Kobalt-Samarium-Magnete dann, wenn man sie schon bei der Fertigung der einzelnen, die Unterkonstruktion von Modell-Fahrzeugen bildenden Teile mittels Druck- oder Spritzguß in die jeweilige Gußform einlegen und beim Gußvorgang mit eingießen würde. Etwaige Feldstärkenverluste der Kobalt-Samarium-Magnete während der kurzzeitigen Temperaturerhöhungen während des Gießens können durch Nachmagnetisieren der Magnete nach Entnahme der Gußteile aus ihrer Form kompensiert werden.The very small despite their great magnetic effect. Dimensions of cobalt samarium magnets allow them to be used in parts of the substructure of model vehicles, e.g. in oil coolers, on or in the bogies of or in equipment boxes under the Model D train wagons, in pressure vessels or the like, practically invisible to the outside viewer, whereby they have to be positioned just above the rail made of ferromagnetic material in order to be able to use them to be able to exercise full magnetic effect optimally. The cobalt samarium magnets would be completely invisible if they were inserted into the respective mold by means of pressure or injection molding during the manufacture of the individual parts that form the substructure of model vehicles and cast in during the casting process. Any loss of field strength of the cobalt-samarium magnets during the brief temperature increases during casting can be compensated for by re-magnetizing the magnets after the castings have been removed from their mold.

Während man beispielsweise bei Modell-Eisenbahnen bisher die für das System Antriebsrad/Schiene erforderliche Haftreibung durch in der Lokomotive bzw. im Triebwagen eigens angeordnete Zusatzwichte aus Metall erzielt, kann man bei Verwendung von Kobalt-Samarium-Magneten auf jedes überflüssige Gewicht in Trieb- oder sonstigen Eisenbahnwagen verzichten. Dieses hat den Vorteil, daß nunmehr alle Karosserieteile von Modell-Fahrzeugen aus leichten, robusten Werkstoffen, insbesondere Kunststoffen, gefertigt werden können. Die Leichtbauweise könnte zu erheblichen Kostenreduzierungen bei der Herstellung von Modell-Fahrzeugen führen. Außerdem dürfte die Lebensdauer eines in Leichtbauweise produzierten Modell-Fahrzeugs im Vergleich zu den bisher in schwererer Qualität gebauten Modell-Fahrzeugen größer sein, da bei einem ungewollten Fall auf Steinboden od. dgl. die Aufprallwucht geringer ist.While, for example, model railroads have so far achieved the static friction required for the drive wheel / rail system by using additional weights made of metal arranged in the locomotive or in the railcar, when using cobalt samarium magnets, any superfluous weight in the drive or waive other railway wagons. This has the advantage that now all body parts of model vehicles can be made from light, robust materials, in particular plastics. The lightweight construction could lead to considerable cost reductions in the production of model vehicles. In addition, the lifespan of a model vehicle produced in lightweight construction is likely to be longer compared to the model vehicles built to date in heavier quality, since the impact force is lower in the event of an unintentional fall on stone floor or the like.

Bei der Dimensionierung der erfindungsgemäß verwendeten Dauermagnete hoher magnetischer Feldstärke, insbesondere der Kobalt-Samarium-Magnete, in Bezug auf die sie aufnehmenden Modell-Fahrzeuge, muß eine vernünftige Abwägung und Abstimmung zwischen den angestrebten Zielen, nämlich einer guten Haftreibung zwischen dem System Antriebsrad/ Schiene einerseits und der Forderung nach einer nicht allzu hohen Lagerbelastung der Achslager von Triebwagen und/oder Eisenbahnwagen andererseits, getroffen werden. Möglicherweise müssen die herkömmlichen Lager von Modell-Fahrzeugen unter Berücksichtigung des erhöhten Lagerdruckes verstärkt werden, der durch die die Magnete tragende und somit von der ferromagnetischen Leittrasse angezogene, die Lager belastende Karosserie erzeugt wird.When dimensioning the permanent magnets of high magnetic field strength used in accordance with the invention, in particular the cobalt samarium magnets, in relation to the model vehicles that receive them, a sensible consideration and coordination between the desired goals, namely a good static friction between the drive wheel / rail system on the one hand and the demand for a not too high bearing load on the axle bearings of railcars and / or railroad cars on the other hand. The conventional bearings of model vehicles may need to be strengthened, taking into account the increased bearing pressure generated by the body that carries the magnets and is thus attracted to the ferromagnetic guideway, which stresses the bearings.

Schließlich könnte die stark erhöhte Haftung der Antriebsräder eines Triebwagens oder der Laufräder der zu ziehenden Wagen einer Modell-Eisenbahn dazu führen, daß wegen des nun stark verminderten Schlupfs zwischen Rad und Schiene enge Kurven nicht oder nur schwer durchfahren werden können, wenn das kurvenäußere Rade und das kurveninnnere Rade starr über eine Achse miteinander verbunden sind. Dieses Problem ließe sich im Bedarfsfalle dadurch lösen, daß zwischen den Antriebsrädern eines Triebwagens ein Differentialgetriebe angeordnet werden müßte. Die Laufräder der Eisenbahnwagen dürften nicht mehr starr miteinander verbunden, sondern nur noch frei an ihrer Achse gelagert werden.Finally, the greatly increased adhesion of the drive wheels of a railcar or the wheels of the wagons to be pulled on a model railroad could lead to the fact that, due to the now greatly reduced slip between wheel and rail, tight corners cannot be driven through or only with difficulty if the outside wheel and the inside wheel is rigidly connected to each other via an axis. If necessary, this problem could be solved by arranging a differential gear between the drive wheels of a railcar. The wheels of the railway wagons should no longer be rigidly connected to each other, but should only be freely stored on their axis.

Falls die gemäß der Erfindung verwendeten Dauermagnete, aus welchen Gründen auch immer, nicht ständig an den Modell-Fahrzeugen angebracht sein sollen, könnte man sie an diesen auch nachträglich anbringbar oder von diesen wieder entfernbar ausbilden.If, for whatever reason, the permanent magnets used according to the invention are not to be permanently attached to the model vehicles, they could also be attached to them or removed therefrom.

Ein gemäß der Erfindung ausgestaltetes Modell-Fahrzeug könnte auch mit Rädern aus elektrisch nicht-leitendem Material, beispielsweise aus Kunststoff, hergestellt werden, wenn die Stromaufnahme von der Leittrasse über Schleifkontakte erfolgt.A model vehicle designed according to the invention could also be produced with wheels made of electrically non-conductive material, for example made of plastic, if the current is drawn from the control route via sliding contacts.

Bei Verwendung von nicht-magnetischem Schienen-Material für Modell-Eisenbahnen, wie Messing, Alpaka, Kunststoff od. dgl., könnte man im Bereich größerer Steigungen oder in engen Bahnkurven eine erforderlichenfalls rostgeschützte Eisenschiene zwischen den beiden Schienensträngen anordnen, um den gewünschten Anpreßeffekt gerade und ausschließlich in den Bereichen zu erzielen, wo ein Durchrutschen der Antriebsräder oder ein Entgleisen der Modell-Eisenbahn droht. Auf ebener und/oder geradlinig verlaufender Strecke wäre der Anpreßeffekt ohnedies kaum erforderlich, möglicherweise noch nicht einmal erwünscht. Die auf solcher Strecke verlaufenden Schienenstränge, insbesondere von im Freien aufgebauten Gartenbahnen, aus rostfreien Nicht-Eisenmetallen hergestellt sein. Dadurch würde die Wirkung von unter der Modell-Eisenbahn angebrachten Dauermagneten aufgehoben. Dies hätte möglicherweise zur Folge, daß die vorstehend erwähnte erhöhte Beanspruchung der Achslager der Modell-Eisenbahn im Bereich der Nicht-Eisen-Schienenteile vollkommen entfiele.When using non-magnetic rail material for model railways, such as brass, alpaca, plastic or the like, one could arrange a rust-protected iron rail between the two rail tracks in the area of larger slopes or in narrow rail curves, in order to achieve the desired contact effect and can only be achieved in areas where the drive wheels are slipping or the model railroad is derailed. In any case, the contact effect would hardly be necessary on a level and / or straight line, and may not even be desirable. The rail tracks running on such a route, in particular of garden railways built outdoors, are made of rustproof non-ferrous metals. This would cancel out the effect of permanent magnets attached under the model railway. This could have the consequence that the above-mentioned increased stress on the axle bearings of the model railroad in the area of the non-iron rail parts would be completely eliminated.

Es liegt ferner im Rahmen dieser Erfindung, außer der Möglichkeit, bereits existierende Modell-Fahrzeuge mit Dauermagneten nachrüsten zu können, auch die Leittrasse entsprechend umrüsten zu können. Es ist denkbar, Leittrassen aus elektrisch nicht-leitfähigem Material so auszugestalten, daß sie im Bereich von Steigungen und/oder Kurven nachträglich mit abnehmbar ausgebildeten ferromagnetischen Leitbändern versehen werden können, in deren Bereich dann der erwünschte Effekt eines hohen Anpreßdruckes der Antriebsräder auf der Leittrasse und einer befriedigenden Laufstabilität des ganzen Fahrzeugs erzielt wird.It is also within the scope of this invention, in addition to being able to retrofit existing model vehicles with permanent magnets, to be able to retrofit the control route accordingly. It is conceivable to design guide lines made of electrically non-conductive material so that they can be provided with removable ferromagnetic guide strips in the area of slopes and / or curves, in the area of which the desired effect of a high contact pressure of the drive wheels on the guide line and a satisfactory running stability of the whole vehicle is achieved.

Bedingt durch die kleinen Massen und Gewichte eines Modell-Spielfahrzeugs, insbesondere einer Modell-Eisenbahn, war es bisher nicht möglich, gut funktionierende Modell-Zahnradbahnen herzustellen. Tiebfahrzeuge mit Waggons haben immer die Tendenz, in der Zahnstange hochzuklettern, auszuhängen, zu entgleisen und abzustürzen. Bei Erhöhung des Lokgewichtes zur Verhinderung des Aufsteigens in der Zahnstange wird auch eine höhere Lokleistung erforderlich. Dazu kommt, daß für den Zahnradeingriff nur ein Bruchteil des Gewichtes aktiv für diesen Zweck zur Anwendung kommt, da diese Mehrkraft nicht senkrecht tur Zahnstange, sondern in Richtung Schwerkraft wirkt (Gravitation).Due to the small masses and weights of a model toy vehicle, especially a model train, it has not been possible to produce well-functioning model cogwheel trains. Railcars with wagons always have a tendency to climb up, unhook, derail and crash on the rack. If the weight of the locomotive is increased to prevent it rising in the rack, a higher locomotive power is also required. In addition, only a fraction of the weight is actively used for this purpose for gear meshing, since this additional force does not act vertically on the toothed rack, but in the direction of gravity (gravitation).

Durch Anbringung geeigneter Magnete an den Triebfahrzeugen über den beiden Schienen oder über der Zahnstange im richtigen Abstand werden die Fahrzeuge senkrecht an die Zahnstange gezogen. Das Zahnrad kann somit nur noch an der Zahnstange aufsteigen, wenn die Magnetkraft der Maanete überwunden wird, was bei richtig gewähltem Eingriffswinkel des Zahnstangengetriebes unterbunden wird. Durch diese Zusatzeinrichtungen können bei geringem Lokgewicht beliebige Steigungen bewältigt werden. Die Anhängelast ist durch die Leistung der Motore der Triebfahrzeuge begrenzt.By attaching suitable magnets to the traction vehicles above the two rails or above the rack at the correct distance, the vehicles are pulled perpendicular to the rack. The gear wheel can therefore only ascend on the rack if the magnetic force of the Maanete is overcome, which is prevented if the pressure angle of the rack and pinion gear is selected correctly. With these additional devices, any gradients can be mastered with a low locomotive weight. The trailer load is limited by the performance of the engines of the traction vehicles.

Die Dauermagnete 2 können aber auch selbst als andere Teile der Unterkonstruktion 3 des Modell-Eisenbahnfahrzeugs 1, etwa als ein Druckbehälter 5 oder als ein Gerätekasten 6, ausgebildet sein. Die Magnete können erfindungsgemäß aber auch in diesen Behältern 5,6 oder im Fahrgestell 4 schon bei Herstellung derselben mit eingegcssen und somit für das Auge unsichtbar darin verborgen sein. Der Kraftlinienverlauf N,S der Magnete 2 verläuft zur Leittrasse 7 senkrecht. Bei Modell-Triebwagen könnten, was hier nicht bildlich dargestellt ist, die Dauermagnete auch in den zwischen den Drehgestellen modellhaft nachgebildeten ölkühlern und damit für das Auge auch des kritischen Modellbahn-Enthusiasten unsichtbar - angeordnet werden.According to FIG. 1, a model railroad car 1 placed on a guideway (here: railroad track) 7 has a substructure 3 with two bogies or bogies 4, each with two wheels 8. At each point of the bogies or bogies 4 that is as invisible as possible, a small permanent magnet 2 with a high field strength, as far as possible a rare earth magnet, such as a cobalt samarium magnet or the like, is either permanent or removable on both sides of the model railway wagon appropriate. The permanent magnets 2 can also be designed as other parts of the substructure 3 of the model railway vehicle 1, for example as a pressure vessel 5 or as a device box 6. According to the invention, the magnets can also be cast into these containers 5, 6 or in the chassis 4 when they are being produced and can therefore be hidden therein from the eye. The line of force N, S of the magnets 2 is perpendicular to the guide line 7. In the case of model railcars, the permanent magnets could also be arranged in the oil coolers modeled between the bogies and thus invisible to the eye of the critical model railroad enthusiast, which is not shown here.

Fig. 2 zeigt eine schematische Darstellung einer Modell-Zahnradbahn 19, deren Räder, wie üblich,auf einer Doppelschiene 22,23 gelagert sind. Zwischen den beiden Schienensträngen 22,23 ist vorzugsweise bei Steilstrecken eine ` Zahnstange 18 angeordnet und an den Schwellen befestigt. An der Unterseite der Modell-Zahnradbahn 19 ist ein zu einem Zahntrieb 21 gehörendes Ritzel 20 angeordnet, das in Gebrauchslage mit der Zahnstange 18 in Eingriff steht. Zur Verhinderung des Aufsteigens des Ritzels 20 an der Zahnstange 18, insbesondere bei sehr steilen Strecken, wird die Modell-Zahnradbahn 19 mittels Dauermagnete 24 an die Schienenstränge 22,23 gezogen, wodurch auch dafür Sorge getragen ist, daß das Ritzel 20 stets in Eingriff mit der Zahnstange 18 verbleibt, so daß das gefürchtete Aufsteigen der Zahnflanken und Ausklinken des Zahntriebes 21 verhindert wird. Zur Erzielung einer möglichst senkrecht auf die Schienen 22,23 wirkenden Anziehkraft und Sicherstellung, daß das Ritzel 20 nicht an der Zahnstange 18 aufsteigt, muß dafür gesorgt werden, daß die Dauermagnete 24 oder andere Dauermagnete möglichst nahe am Ritzel 20, entweder vor und hinter diesem oder über diesem, angeordnet weeden. Möglicherweise könnte ein scheibenförmig ausgebildeter, axial magnetisierter Dauermagnet 25 auch im Ritzel 20 selbst vorgesehen werden, welches hinsichtlich der erzielbaren Anziehkraft zwischen Ritzel 20 und Zahnstange 18 optimal wäre.FIG. 2 shows a schematic illustration of a model gear train 19, the wheels of which, as usual, are mounted on a double rail 22, 23. A rack 18 is arranged between the two rail tracks 22, 23, preferably on steep sections, and is fastened to the sleepers. A pinion 20 belonging to a pinion 21 is arranged on the underside of the model gear train 19 and is in engagement with the rack 18 in the position of use. In order to prevent the pinion 20 from rising on the rack 18, particularly on very steep routes, the model gear train 19 is pulled onto the rail tracks 22, 23 by means of permanent magnets 24, which also ensures that the pinion 20 is always in engagement with the rack 18 remains, so that the dreaded rising of the tooth flanks and notching of the pinion 21 is prevented. In order to achieve a pulling force acting as vertically as possible on the rails 22, 23 and to ensure that the pinion 20 does not rise on the rack 18, it must be ensured that the permanent magnets 24 or other permanent magnets are as close as possible to the pinion 20, either in front of and behind it or above it. A disk-shaped, axially magnetized permanent magnet 25 could possibly also be provided in the pinion 20 itself, which would be optimal with regard to the achievable attraction force between pinion 20 and rack 18.

Fig. 3 zweigt eine schematische Darstellung einer Eisenbahnachse 12 mit zwei Rädern 8 aus ferromagnetischem Material. Jeweils an der Innenseite weisen die beiden Räder 8 koaxial angeordnete Dauermagnete 9,10 mit der in Fig. 3 gezeigten Polarität N,S auf. Die beiden Dauermagnete 9,10 sind über die ferromagnetische Achse 12 miteinander verbunden. Die Achse 12 könnte auch aus nicht-ferromagnetischem Material bestehen. Dann müßte sie jedoch mit einem ferromanetischem Überzug 14 zur Gewährleistung des magnetischen Kraftflusses versehen sein. Falls die Achse nach außen hin nicht blank sein, sondern eine nichtferromagnetische Schicht aufweisen sollte, muß sie zumindest einen ferromagnetischen Kern (13) aufweisen. In der dargestellten Form sind die beiden Räder 8 unterschiedlich magnetisiert, das linke bildet den Nordpol, das rechte den Südpol des Dauermagnetsystems.Fig. 3 branches a schematic representation of a railway axis 12 with two wheels 8 made of ferromagnetic material. The two wheels 8 each have coaxial permanent magnets 9, 10 with the polarity N, S shown in FIG. 3 on the inside. The two permanent magnets 9, 10 are connected to one another via the ferromagnetic axis 12. The axis 12 could also consist of non-ferromagnetic material. Then it would have to be provided with a ferromanetic coating 14 to ensure the magnetic flux of force. If the axis should not be bare to the outside, but should have a non-ferromagnetic layer, it must have at least one ferromagnetic core (13). In the form shown, the two wheels 8 are magnetized differently, the left one forms the north pole, the right one the south pole of the permanent magnet system.

Fig. 4 zeigt eine Eisenbahnachse 12 mit zwei Rädern 8, welche an ihren Laufflächen 15 jeweils eine Ringnut 16 zeigen, welche sich radial um einen im Rad 8 eingelassenen Dauermagneten 11 bilden. Diese Ringnut 16 könnte offen sein. Zweckmäßigerweise sollte sie jedoch mit einem nicht-ferromagnetischen Material 17, beispielsweise Messing, verfüllt sein, damit das Rad 8 auf seiner Schiene 22,23 satt aufliegt und problemlos abrollen kann. Die beiden Dauermagnete 11 sorgen ebenfalls für eine gute Haftung Rad/Schiene.4 shows a railway axle 12 with two wheels 8, each of which has an annular groove 16 on its running surfaces 15, which are formed radially around a permanent magnet 11 embedded in the wheel 8. This annular groove 16 could be open. Expediently, however, it should be filled with a non-ferromagnetic material 17, for example brass, so that the wheel 8 lies snugly on its rail 22, 23 and can roll off without problems. The two permanent magnets 11 also ensure good wheel / rail adhesion.
