Description

Die Erfindung betrifft ein Fahrzeugmodell gemäß dem Oberbegriff von Anspruch 1.The invention relates to a vehicle model according to the preamble of claim 1.

Ein derartiges Fahrzeugmodell ist insbesondere als Schienenfahrzeugmodel für eine Modelleisenbahn ausgebildet. Das Fahrzeugmodell weist ein Fahrzeuguntergestell auf, an dem mindestens zwei Achsen drehbar gelagert sind, wobei ein Elektromotor zum Antreiben mindestens einer der Achsen am Fahrzeuguntergestell befestigt ist.Such a vehicle model is designed in particular as a rail vehicle model for a model railroad. The vehicle model has a vehicle underframe on which at least two axles are rotatably mounted, wherein an electric motor for driving at least one of the axles is fastened to the vehicle undercarriage.

Derartige Fahrzeugmodelle werden gewöhnlich mit unterschiedlichen Aufbauten kombiniert, dienen also als Basis für unterschiedliche Modellvarianten. Insbesondere bei Triebfahrzeugen und anderen Funktionsmodellen in Verbindung mit kleinen Maßstäben ist bei derartigen Fahrzeugmodellen der für eine Antriebseinrichtung zur Verfügung stehende Raum sehr beengt. Üblicherweise werden insbesondere Modelleisenbahnen in Maßstäben zwischen 1 : 22,5 und 1 : 220 gefertigt.Such vehicle models are usually combined with different structures, so serve as the basis for different model variants. Especially in traction vehicles and other functional models in conjunction with small scales is in such Vehicle models of space available for a drive device space very cramped. Usually model trains are manufactured in scales between 1: 22.5 and 1: 220.

Die zum Antrieb verwendeten Elektromotoren weisen jedoch immer eine gewisse Mindestgröße auf, um zum einen kostengünstig herstellbar zu sein und um zum anderen ausreichend robust und leistungsstark ausgebildet werden zu können. Während es beispielsweise für Dampflokomotiven mit Tendern möglich ist, den Elektromotor im meist geschlossenen Tender unterzubringen, bietet sich eine derartige Lösung für Triebwagen, die beispielsweise eine Fahrgastzelle über ihre gesamte Länge aufweisen, nicht an. Insbesondere bei kleinen Modellen bzw. keinen Maßstäben kann die Unterbringung des Elektromotors und der zugehörigen Antriebselemente - wie z.B. Achsen, Getriebe, Schwungmassen oder Schleifer - erhebliche Schwierigkeiten bereiten, so dass eine genaue maßstäbliche Nachbildung eines bestimmten Modells nicht immer möglich ist.However, the electric motors used for the drive always have a certain minimum size in order to be inexpensive to produce and to be able to be designed sufficiently robust and powerful to others. While it is possible, for example, for steam locomotives with tenders to accommodate the electric motor in the most closed tender, such a solution for railcars, for example, have a passenger compartment over its entire length, not on. Especially with small models or no scales, the accommodation of the electric motor and the associated drive elements - such. Axles, gears, flywheels or grinders - create considerable difficulties, so that an exact scale reproduction of a particular model is not always possible.

In US 6,641,457 B1 ist ein Modellauto mit einem Fahrzeuguntergestell offenbart, wobei im Fahrzeuguntergestell Unterbrechungen zur zumindest teilweisen Aufnahme eines Motors, von Getrieben und ähnlichem ausgebildet sind. Dadurch soll ein sehr stabiles Untergestell und ein guter Schutz dieser Komponenten erreicht werden.In US 6,641,457 B1 discloses a model car with a vehicle undercarriage, wherein in the vehicle undercarriage interruptions for at least partially receiving a motor, transmissions and the like are formed. This is to achieve a very stable base and good protection of these components.

In US 3,199,371 ist eine Viskosekupplung für Fahrzeugmodelle beschrieben, die teilweise in einer Durchbrechung eines Fahrzeuguntergestells aufgenommen ist. Auch ein Motor des Fahrzeugmodells ist dabei in einem Durchbruch des Fahrzeuguntergestells angeordnet. Eine Motorwelle dieses Motors verläuft dabei parallel zur Mittelebene sowie parallel zur Längsachse des Fahrzeuguntergestells.In US 3,199,371 a viscous coupling for vehicle models is described, which is partially received in an opening of a vehicle undercarriage. An engine of the vehicle model is arranged in a breakthrough of the vehicle undercarriage. A motor shaft of this motor runs parallel to the center plane and parallel to the longitudinal axis of the vehicle undercarriage.

US 533 259 A zeigt nun eine Elektrolokomotive, bei der ein Elektromotor mit einer durchgehenden Antriebswelle über jeweils eine Kupplung und ein Schneckenradgetriebe zwei Achsen der Lokomotive antreibt. Dabei verläuft die Antriebswelle in einem Winkel zur Längsrichtung des Fahrzeugs und gegebenenfalls auch in einem Winkel zu einer durch das Untergestell definierten Ebene. US 533 259 A now shows an electric locomotive, in which an electric motor with a continuous drive shaft via each one clutch and a worm gear drives two axes of the locomotive. In this case, the drive shaft extends at an angle to the longitudinal direction of the vehicle and possibly also at an angle to a plane defined by the base.

DE 198 24 017 A1 betrifft eine Stabilisierungsvorrichtung für ein Modelleisenbahnfahrzeug, wobei ein Elektromotor oberhalb eines Fahrzeuguntergestells aber innerhalb des Gehäuses des Fahrzeugs angeordnet ist. Eine Motorwelle des Motors verläuft dabei parallel zur Längsachse sowie parallel zur Mittelebene des Fahrzeuguntergestells. DE 198 24 017 A1 relates to a stabilizer device for a model railway vehicle, wherein an electric motor above a vehicle undercarriage but within the housing of the Vehicle is arranged. A motor shaft of the motor runs parallel to the longitudinal axis and parallel to the center plane of the vehicle undercarriage.

Der Erfindung liegt daher die Aufgabe zugrunde, die Nachteile des Standes der Technik zu beseitigen und ein Fahrzeugmodell anzugeben, das auch bei kleinen Maßstäben eine modellgerechte Unterbringung eines Elektromotors und der zugehörigen Antriebselemente ermöglicht. Dabei soll die Lösung kostengünstig und mit geringem Aufwand herstellbar sein.The invention is therefore based on the object to eliminate the disadvantages of the prior art and to provide a vehicle model that allows a model-appropriate accommodation of an electric motor and the associated drive elements even at low scales. The solution should be inexpensive and can be produced with little effort.

Gelöst wird diese Aufgabe durch ein Fahrzeugmodell mit den Merkmalen des Anspruchs 1 Ausgestaltungen sind Gegenstand der Ansprüche 2 bis 14.This object is achieved by a vehicle model with the features of claim 1 embodiments are the subject of claims 2 to 14.

Bei einem Fahrzeugmodell, insbesondere einem Schienenfahrzeugmodell für eine Modelleisenbahn, mit einem Fahrzeuguntergestell, das eine Längsachse aufweist und an dem mindestens zwei Achsen drehbar gelagert sind, und mit einem Elektromotor zum Antreiben mindestens einer der Achsen, wobei der Elektromotor am Fahrzeuguntergestell befestigt ist und eine Motorwelle aufweist, die über ein Getriebe mit einer der Achsen verbunden ist, sieht die Erfindung vor, dass der Elektromotor in einem Durchbruch des Fahrzeuguntergestells angeordnet ist.In a vehicle model, in particular a railroad model for a model railway, with a vehicle undercarriage having a longitudinal axis and on which at least two axes are rotatably mounted, and with an electric motor for driving at least one of the axes, wherein the electric motor is fixed to the vehicle underframe and a motor shaft has, which is connected via a gear with one of the axes, the invention provides that the electric motor is arranged in an opening of the vehicle undercarriage.

Der Elektromotor ist also nicht wie üblich an einer Oberseite des Fahrzeuguntergestells befestigt, sondern mittels des Durchbruchs im Fahrzeuguntergestell integriert. Er ragt dabei bevorzugt oberseitig und unterseitig aus dem Fahrzeuguntergestell heraus, so dass die gesamte Bauhöhe für das Fahrzeugmodell stark reduziert ist, selbst wenn der Elektromotor oberseitig weiter aus dem Fahrzeuguntergestell herausragen sollte als unterseitig.The electric motor is therefore not attached as usual to an upper side of the vehicle undercarriage, but integrated by means of the opening in the vehicle undercarriage. It protrudes preferably on the upper side and underside of the vehicle underframe, so that the total height for the vehicle model is greatly reduced, even if the electric motor on the upper side should continue to protrude from the vehicle undercarriage than the underside.

Das Fahrzeuguntergestell kann plattenförmig ausgebildet sein, oder auch aus einzelnen Elementen bestehen, solange es einen für die Aufnahme des Elektromotors geeigneten Durchbruch aufweist. Durch die zumindest teilweise Aufnahme des Elektromotors innerhalb des Fahrzeuguntergestells steht für Aufbauten auf dem Fahrzeuguntergestell sehr viel mehr Bauraum zur Verfügung, der durch den Elektromotor kaum mehr beschränkt wird. So können beispielsweise Triebwagen und andere angetriebene Funktionsmodelle in sehr kleinem Maßstab hergestellt werden, ohne dass der Elektromotor einer maßstabsgetreuen Gestaltung entgegenstehen würde oder in der Fahrgastzelle oder durch Fenster hindurch sichtbar wäre. Auch ist es möglich, mit dem erfindungsgemäßen Fahrzeugmodell Flachwagen oder andere Güter oder Personenwagen zu realisieren, die selbst in kleinen Maßstäben äußerst detail- und naturgetreu gestaltet werden können, was mit herkömmlichen Fahrzeugmodellen nicht möglich ist.The vehicle undercarriage may be plate-shaped, or consist of individual elements, as long as it has a suitable for receiving the electric motor breakthrough. By at least partially receiving the electric motor within the vehicle undercarriage is much more space available for structures on the vehicle undercarriage, which is hardly limited by the electric motor. For example, railcars and other powered functional models can be made on a very small scale without the electric motor interfering with a true-to-scale design, or being visible in the passenger compartment or through windows. It is also possible to realize with the vehicle model according to the invention flat car or other goods or passenger cars, the extremely detail and even in small scales true to nature, which is not possible with conventional vehicle models.

Eine weitere Verbesserung der Raumausnutzung ergibt sich dadurch, dass die Motorwelle des Elektromotors zumindest abschnittsweise parallel zu einer Mittelebene des Fahrzeuguntergestells und in einem Winkel schräg zur Längsachse angeordnet ist. Die gewöhnlich zentrisch im Elektromotor gelagerte Motorwelle, die in der Mittelebene des Fahrzeuguntergestells oder leicht nach oben versetzt parallel zu dieser Mittelebene verläuft, liegt also nicht wie bisher üblich parallel zur Fahrzeuglängsachse. Sie verläuft vielmehr in einem spitzen Winkel dazu. Damit liegt auch der Elektromotor in einem spitzen Winkel zur Längsachse des Fahrzeuguntergestells, d.h. der Motor ist in etwa diagonal in das Fahrzeuguntergestell eingesetzt. Dadurch wird auf überraschend einfache Weise die für den Elektromotor und dessen Motorwelle zur Verfügung stehende Länge innerhalb des Fahrzeuguntergestells vergrößert, was sich äußerst günstig auf die Gestaltung und Dimensionierung der an die Motorwelle angeschlossenen Funktionselemente, wie z.B. Getriebe oder Schwungmassen, auswirkt. Der Winkel zwischen der Motorwelle des Elektromotors und der Längsachse des Fahrzeuguntergestells liegt bevorzugt zwischen 3° und 10°, besonders bevorzugt zwischen 5° und 8°.A further improvement of the space utilization results from the fact that the motor shaft of the electric motor is arranged at least in sections parallel to a median plane of the vehicle undercarriage and at an angle oblique to the longitudinal axis. The usually centrally mounted in the electric motor motor shaft, which is parallel to this center plane in the center plane of the vehicle undercarriage or slightly upwards, is therefore not parallel to the vehicle longitudinal axis as usual. It rather runs at an acute angle. Thus, the electric motor is also at an acute angle to the longitudinal axis of the vehicle undercarriage, i. The engine is inserted approximately diagonally into the vehicle chassis. Thereby, in a surprisingly simple manner, the length available within the vehicle undercarriage for the electric motor and its motor shaft is increased, which is extremely favorable for the design and dimensioning of the functional elements connected to the motor shaft, such as e.g. Gear or flywheels affects. The angle between the motor shaft of the electric motor and the longitudinal axis of the vehicle undercarriage is preferably between 3 ° and 10 °, more preferably between 5 ° and 8 °.

Eine weitere wichtige Ausgestaltung der Erfindung sieht vor, dass das Getriebe ein Schneckengetriebe ist, mit einer Schnecke und einem Schneckenrad, wobei die Schnecke drehfest auf der Motorwelle des Elektromotors und das Schneckenrad drehfest auf einer der Achsen angeordnet ist. Damit weist das Getriebe zunächst eine sehr kompakte Bauform auf, was sich ebenfalls günstig auf den Platzbedarf des erfindungsgemäßen Fahrzeugmodells auswirkt. Gleichzeitig sorgt das Schneckengetriebe für eine Selbsthemmung des Antriebs, d.h. das Fahrzeugmodell kann nicht unbeabsichtigt wegrollen.Another important embodiment of the invention provides that the transmission is a worm gear, with a worm and a worm wheel, the worm rotatably on the motor shaft of the electric motor and the worm wheel rotatably mounted on one of the axes. Thus, the transmission initially has a very compact design, which also has a favorable effect on the space requirement of the vehicle model according to the invention. At the same time, the worm gear ensures self-locking of the drive, i. the vehicle model can not roll away unintentionally.

Ein wesentlicher Vorteil der vorliegenden Erfindung besteht allerdings darin, dass die Schnecke durch die Schräganordnung des Elektromotors bzw. der Motorwelle relativ zur Längsachse des Fahrzeuguntergestells ebenfalls schräg über dem Schneckenrad liegt, das im Wesentlichen senkrecht auf der Achse des Fahrzeuguntergestells befestigt ist. Das Schneckenrad muss dadurch nicht mehr mit einer Schrägverzahnung versehen werden, was bei herkömmlichen Fahrzeugmodellen notwendig ist, wenn die Schnecke und das Schneckenrad mit einem nur geringen Spiel ineinandergreifen sollen. Dank der erfindungsgemäßen Ausgestaltung können vielmehr einfache handelsübliche Zahnräder mit Geradverzahnung verwendet werden, was sich äußerst günstig auf die Herstellkosten auswirkt. Dennoch kann die Schnecke mit geringst möglichem Spiel in das Schneckenrad eingreifen, insbesondere dann, wenn der Winkel zwischen der Motorwelle und der Längsachse des Fahrzeuguntergestells in etwa der Steigung der Schnecke entspricht. Damit lassen sich mit dem Fahrzeugmodell naturgetreue Bewegungen ausführen, d.h. das Fahrzeugmodell kann sich sehr gleichmäßig und präzise bewegen.A significant advantage of the present invention, however, is that the worm is also inclined by the oblique arrangement of the electric motor or the motor shaft relative to the longitudinal axis of the vehicle undercarriage above the worm wheel, which is mounted substantially perpendicular to the axis of the vehicle undercarriage. The worm wheel must therefore no longer be provided with a helical toothing, which is necessary in conventional vehicle models, when the worm and the worm wheel with a small clearance to mesh. Thanks to the inventive design rather simple commercial gears can be used with straight teeth, which is extremely favorable effect on the production costs. Nevertheless, the worm can engage in the worm wheel with the least possible play, in particular if the angle between the motor shaft and the longitudinal axis of the vehicle undercarriage corresponds approximately to the pitch of the worm. This allows the vehicle model lifelike movements to perform, ie the vehicle model can move very smoothly and precisely.

Eine noch andere Ausführungsform der Erfindung sieht vor, dass die Motorwelle des Elektromotors zumindest abschnittsweise einen flexiblen Abschnitt aufweist. Dadurch ist es möglich, die Drehachse der Schnecke bezüglich der Drehachse des Elektromotors beziehungsweise der Motorwelle im Winkel zu verändern oder in der Höhe zu versetzen, d.h. die Anordnung der Schnecke bezüglich des Elektromotors kann flexibel erfolgen, insbesondere dann, wenn der Elektromotor in dem Fahrzeuguntergestell abgesenkt ist.Yet another embodiment of the invention provides that the motor shaft of the electric motor has a flexible section at least in sections. This makes it possible to angularly change or elevate the axis of rotation of the worm with respect to the axis of rotation of the electric motor or the motor shaft, i. the arrangement of the screw with respect to the electric motor can be flexible, especially when the electric motor is lowered in the vehicle undercarriage.

Dazu trägt insbesondere bei, wenn die Schnecke an den flexiblen Abschnitt anschließt und in einem Winkel schräg zur Mittelebene des Fahrzeuguntergestells in das Schneckenrad eingreift. Dabei ist es möglich, die Schnecke im Bereich einer Oberseite des Fahrzeuguntergestells anzuordnen oder das auf der Achse des Fahrzeuguntergestells sitzende Schneckenrad ausreichend groß zu dimensionieren. Während also der Elektromotor mit seiner Motorwelle in dem Durchbruch des Fahrzeuguntergestells abgesenkt ist, kann die Schnecke - um das Schneckenrad der Achse optimal zu erreichen - im Winkel leicht ansteigend angeordnet werden, ohne den Winkel zwischen der Schnecke und dem Schneckenrad relativ zur Längsachse des Fahrzeuguntergestells verändern zu müssen. Der Winkel zwischen der Drehachse der Schnecke und der Mittelebene des Fahrzeuguntergestells liegt bevorzugt zwischen 10° und 25°.Contributes in particular, when the screw connects to the flexible portion and engages at an angle oblique to the median plane of the vehicle undercarriage in the worm wheel. It is possible to arrange the screw in the region of an upper side of the vehicle undercarriage or to dimension the worm wheel seated on the axle of the vehicle undercarriage sufficiently large. Thus, while the electric motor is lowered with its motor shaft in the opening of the vehicle undercarriage, the worm - to optimally reach the worm wheel of the axis - can be arranged slightly rising at an angle without changing the angle between the worm and the worm wheel relative to the longitudinal axis of the vehicle undercarriage to have to. The angle between the axis of rotation of the screw and the center plane of the vehicle undercarriage is preferably between 10 ° and 25 °.

Das gesamte Fahrzeug erhält mithin eine äußerst kompakte Bauform, wobei der diagonal im Fahrzeuguntergestell liegende Antriebsstrang bestehend aus Elektromotor, Motorwelle und Getriebe optimal an die Bedürfnisse des jeweiligen Modells angepasst werden kann, was sich äußerst günstig auf die Lauf- und Fahreigenschaften, insbesondere von sehr kleinen Fahrzeugmodellen in kleinem Maßstab auswirkt. Weil zudem die Motorwelle des Elektromotors und die Schnecke des Getriebes - in Längsrichtung der Motorwelle betrachtet - auf einer Linie fluchten, können für das Fahrzeugmodell Elektromotoren mit geringerer Leistungsaufnahme verwendet werden, weil das zum Drehen der Motorwelle notwendige Drehmoment - trotz des ansteigenden Winkels zwischen Schnecke und Fahrzeuguntergestell relativ zu dessen Mittelebene - relativ klein ist. Auch dies wirkt sich günstig auf die Herstellkosten und die Lebensdauer des Fahrzeugmodells aus.The entire vehicle thus receives an extremely compact design, the lying diagonally in the vehicle undercarriage powertrain consisting of electric motor, motor shaft and gearbox can be optimally adapted to the needs of each model, which is extremely favorable to the running and handling characteristics, especially of very small Vehicle models on a small scale affects. In addition, because the motor shaft of the electric motor and the screw of the transmission - viewed in the longitudinal direction of the motor shaft - aligned on a line, can be used for the vehicle model electric motors with lower power consumption, because the torque required to rotate the motor shaft - despite the increasing angle between worm and Vehicle undercarriage relative to its Midplane - is relatively small. This also has a favorable effect on the production costs and the service life of the vehicle model.

Auf der Motorwelle ist bevorzugt eine Schwungmasse angeordnet, die einen möglichst gleichmäßigen Lauf des Fahrzeugmodells ermöglicht. Weil jedoch die Motorwelle des Elektromotors parallel zur Mittelebene des Fahrzeuguntergestells und in einem Winkel schräg zur Längsachse angeordnet ist, steht für die Schwungmasse im Vergleich zu herkömmlichen Fahrzeugmodellen innerhalb des Fahrzeugs deutlich mehr Platz zur Verfügung, d.h. die Schwungmasse kann deutlich vergrößert werden, was die Laufeigenschaften des Fahrzeugs deutlich verbessert.On the motor shaft, a flywheel is preferably arranged, which allows a uniform possible running of the vehicle model. However, because the motor shaft of the electric motor is arranged parallel to the center plane of the vehicle undercarriage and at an angle oblique to the longitudinal axis, the flywheel mass is significantly more space available compared to conventional vehicle models within the vehicle, i. The flywheel mass can be significantly increased, which significantly improves the running characteristics of the vehicle.

Damit sich der Einbau der Schwungmasse nicht negativ auf die Bauhöhe des Fahrzeugmodells auswirkt, sieht die Erfindung vor, dass die Schwungmasse zusammen mit dem Elektromotor in dem Durchbruch des Fahrzeuguntergestells liegt.Thus, the installation of the flywheel does not adversely affect the height of the vehicle model, the invention provides that the flywheel is located together with the electric motor in the opening of the vehicle undercarriage.

Konstruktiv ist es weiter günstig, wenn die Schwungmasse einen Teil der Motorwelle bildet, die Motorwelle fortsetzt oder mit dieser einstückig ist.Constructively, it is further favorable if the flywheel forms part of the motor shaft, the motor shaft continues or is integral with this.

In einer noch anderen Ausführungsform sieht die Erfindung vor, dass der flexible Abschnitt der Motorwelle zwischen der Schwungmasse und der Schnecke liegt und eine flexible Wellenkupplung bildet, welche die Schwungmasse und die Schnecke drehfest miteinander verbindet. Die Wellenkupplung kann beispielsweise als Metallbalg-Kupplung, als Elastomer-Kupplung, oder auch als biegsames Wellenelement oder als Gelenkwelle ausgebildet sein. Gemäß einer Weiterbildung der Erfindung weist das Fahrzeuguntergestell im Bereich des Getriebes eine Ausnehmung auf, die zu einer Längsseite des Fahrzeuguntergestells hin offen ist. Der für das Schneckenrad erforderliche Bauraum wird also ebenfalls im Wesentlichen innerhalb des Fahrzeuguntergestells zur Verfügung gestellt, sodass die Bauhöhe des Fahrzeugmodells klein gehalten wird und viel Raum für geplante Aufbauten zur Verfügung steht. Durch die zur Längsseite hin offene Ausgestaltung der Ausnehmung ergibt sich dabei eine einfache Montage.In yet another embodiment, the invention provides that the flexible portion of the motor shaft is located between the flywheel and the worm and forms a flexible shaft coupling, which rotatably connects the flywheel and the worm with each other. The shaft coupling may be formed, for example, as a metal bellows coupling, as an elastomeric coupling, or as a flexible shaft element or as a propeller shaft. According to one embodiment of the invention, the vehicle undercarriage in the region of the transmission on a recess which is open to a longitudinal side of the vehicle undercarriage. The space required for the worm wheel is therefore also provided substantially within the vehicle undercarriage, so that the height of the vehicle model is kept small and plenty of room for planned structures is available. By open to the longitudinal side configuration of the recess results in a simple installation.

Eine besonders einfache Möglichkeit, die Schnecke und die Motorwelle am Fahrzeuguntergestell zu befestigen und die auftretenden Kräfte auf das Fahrzeuguntergestell zu übertragen, besteht darin, die Motorwelle und/oder die Schnecke in einem Lager drehbar zu lagern, wobei die Schnecke auch beidseitig gelagert werden kann, was sich günstig auf die Stabilität des Antriebs auswirkt.A particularly simple way to attach the worm and the motor shaft to the vehicle undercarriage and to transfer the forces occurring to the vehicle undercarriage is to rotate the motor shaft and / or the worm in a bearing store, where the worm can also be stored on both sides, which has a favorable effect on the stability of the drive.

Um das Fahrzeugmodell über Schienen, insbesondere Eisenbahnschienen, mit Strom zu versorgen, ist erfindungsgemäß vorgesehen, dass an den Achsen Räder angeordnet sind, die innenliegende Spurkränze und dem Fahrzeuguntergestell zugewandte Innenseiten aufweisen, wobei an den Innenseiten der Spurkränze blattfederartige Stromabnehmer anliegen. Über diese Stromabnehmer kann dann von den Schienen abgenommene elektrische Energie in Form von Strom beziehungsweise Spannung dem Elektromotor oder anderen elektrischen Verbrauchern im Fahrzeugmodell zugeführt werden. Durch die blattfederartige Ausgestaltung können die Stromabnehmer dabei mit einer Vorspannung an der Innenseite der Spurkränze anliegen, so dass stets ein ausreichend sicherer elektrischer Kontakt gewährleistet ist. Es versteht sich, dass die Räder des Fahrzeugmodells aus Metall gefertigt und jeweils isoliert auf den Achsen gelagert sind.To supply the vehicle model on rails, especially railroad tracks, with electricity, the invention provides that wheels are arranged on the axles, which have inner flanges and the vehicle underframe facing inner sides, wherein rest on the inner sides of the flanges leaf spring-like current collector. About this pantograph then removed from the rails electrical energy in the form of electricity or voltage can be supplied to the electric motor or other electrical consumers in the vehicle model. Due to the leaf-spring-like configuration, the current collector can rest with a bias on the inside of the flanges, so that always a sufficiently secure electrical contact is ensured. It is understood that the wheels of the vehicle model are made of metal and each stored isolated on the axles.

Von Vorteil ist ferner, wenn die Stromabnehmer in Schlitzen im Fahrzeuguntergestell geführt sind, die zu einer Oberseite des Fahrzeuguntergestells hin offen sind. Damit ergibt sich eine stabile Halterung der Stromabnehmer am Fahrzeuguntergestell, wobei durch die zur Oberseite offene Ausgestaltung der Schlitze zum einen eine einfache Fertigung möglich ist, zum anderen ein leichter Zugang zu den Stromabnehmer erfolgen kann, um die Stromabnehmer mit den elektrischen Anschlüssen des Elektromotors zu verbinden, beispielsweise durch Verlöten.It is also advantageous if the current collectors are guided in slots in the vehicle underframe, which are open to an upper side of the vehicle undercarriage. This results in a stable mounting of the pantograph on the vehicle undercarriage, which is on the one hand by the open design of the slots for easy production is possible, on the other hand, easy access to the pantograph can be done to connect the pantograph to the electrical terminals of the electric motor , for example by soldering.

Eine weitere wichtige Ausgestaltung des erfindungsgemäßen Fahrzeugmodells sieht vor, dass der Elektromotor auf seinen einander gegenüberliegenden Seiten zwei Motorwellen aufweist und etwa mittig zwischen den zwei angetriebenen Achsen angeordnet ist.Another important embodiment of the vehicle model according to the invention provides that the electric motor has on its opposite sides two motor shafts and is arranged approximately centrally between the two driven axles.

Dadurch ist es bei einer äußerst kompakten Bauform sehr einfach möglich, beide Achsen des Fahrzeugmodells synchron anzutreiben. Bei einer Ausgestaltung des Elektromotors beispielsweise als Glockenläufermotor ist es zudem möglich, die zwei Motorwellen einteilig auszubilden und zentrisch durch den Elektromotor hindurchzuführen. In jedem Fall steht an beiden Stirnseiten des Elektromotors das erzeugte Antriebsmoment über die Motorwelle und die Getriebe zur Verfügung und kann in gleicher Weise auf die anzutreibende Achsen übertragen werden. Durch die Verwendung der Schneckengetriebe, die jeweils endseitig an der bzw. den Motorwellen oder - je nach Bauform - an den Schwungmassen angeflanscht werden können, ist eine Untersetzung möglich, sodass der Elektromotor mit hoher Drehzahl betrieben werden kann. Der Elektromotor kann dadurch relativ klein gehalten werden. Dennoch ist ein äußerst gleichmäßiger Lauf des Fahrzeugs gewährleistet.This makes it very easy in an extremely compact design, synchronously to drive both axles of the vehicle model. In one embodiment of the electric motor, for example as a bell-rotor motor, it is also possible to form the two motor shafts in one piece and to guide them centrally through the electric motor. In any case, the generated drive torque is available on both end sides of the electric motor via the motor shaft and the gearbox and can be transmitted in the same way to the axes to be driven. By using the worm gear, which can each be flanged to the end of the motor shaft or - depending on the design - to the flywheel masses, a reduction is possible, so that the electric motor operated at high speed can be. The electric motor can be kept relatively small. Nevertheless, an extremely smooth running of the vehicle is guaranteed.

Die Verbindung der Schnecke mit der Motorwelle kann bei Bedarf auch indirekt, also beispielsweise über ein zwischengeschaltetes Getriebe, erfolgen. Wichtig ist nur, dass die Schnecke durch den Elektromotor in Rotation versetzt werden kann. Das Schneckenradgetriebe ermöglicht eine relativ große Untersetzung und kann beispielsweise eine Selbsthemmung bereitstellen, die einen sicheren Halt des Fahrzeugmodells im stromlosen Zustand gewährleistet. Ein Schneckenradgetriebe ist darüber hinaus nahezu wartungsfrei und weist eine hohe Lebensdauer auf.If necessary, the connection of the worm to the motor shaft can also take place indirectly, for example via an intermediate gearbox. It is only important that the worm can be rotated by the electric motor. The worm gear allows a relatively large reduction and can for example provide a self-locking, which ensures a secure hold of the vehicle model in the de-energized state. A worm gear is also almost maintenance-free and has a long service life.

Weitere Vorteile ergeben sich, wenn die Getriebe diagonal gegenüberliegenden Eckbereichen des Fahrzeuguntergestells zugeordnet sind. Dadurch wird nicht nur erreicht, dass die Motorwellen insgesamt verlängert und die Schnecken mit geradverzahnten Schneckenrädern betrieben werden können, die nicht mittig, sondern seitlich auf den Achsen sitzen. Es entsteht vor allem im mittleren Bereich der Achsen des Fahrzeuguntergestells zusätzlicher Bauraum der genutzt werden kann, beispielsweise für die Anordnung eines Mittelschleifers, der für die Ausbildung von Dreileiterfahrzeugen notwendig ist und in elektrischem Kontakt mit dem Mittelleiter des Gleises und der Achse stehen muss.Further advantages arise when the transmission are assigned diagonally opposite corner regions of the vehicle undercarriage. This not only ensures that the motor shafts are lengthened overall and the screws can be operated with straight-toothed worm wheels, which sit not on the center, but laterally on the axles. It arises especially in the central region of the axles of the vehicle undercarriage additional space can be used, for example, for the arrangement of a center grinder, which is necessary for the formation of three-wire vehicles and must be in electrical contact with the center conductor of the track and the axle.

Fig. 1 zeigt ein Fahrzeugmodell 1, das als Schienenfahrzeugmodell für eine Modelleisenbahn ausgebildet ist. Das Fahrzeugmodell 1 weist ein Fahrzeuguntergestell 2 auf, wobei an gegenüberliegenden Enden des Fahrzeuguntergestells 2 Räder 3, 4, 5, 6 vorgesehen sind. Die Räder 3, 4, 5, 6 sind jeweils paarweise über eine Achse 7, 8 drehfest miteinander verbunden, die drehbar am Fahrzeuguntergestell 2 gelagert ist. Das Fahrzeuguntergestell 2 ist im Bereich der Räder 3, 4, 5, 6 seitlich verjüngt und weist entlang einer Längsachse 43 in einem mittleren Bereich zwischen den Achsen 7, 8 eine Breite auf, die etwa dem Abstand der Außenseiten der Räder 3, 4, 5, 6 entspricht oder sogar geringfügig größer sein kann. Fig. 1 shows a vehicle model 1, which is designed as a rail vehicle model for a model railroad. The vehicle model 1 has a vehicle underframe 2, wherein at opposite ends of the vehicle undercarriage 2 wheels 3, 4, 5, 6 are provided. The wheels 3, 4, 5, 6 are each rotatably connected in pairs via an axle 7, 8, which is rotatably mounted on the vehicle undercarriage 2. The vehicle undercarriage 2 is in the range the wheels 3, 4, 5, 6 tapers laterally and along a longitudinal axis 43 in a central region between the axes 7, 8 has a width which corresponds approximately to the distance of the outer sides of the wheels 3, 4, 5, 6 or even slightly can be bigger.

In einem mittleren Bereich 9 des Fahrzeuguntergestells 2 ist schräg zur Längsachse 43 ein Durchbruch 10 vorgesehen, in dem ein Elektromotor 11 angeordnet ist. Der Elektromotor 11 ist über eine Drehmomentstütze 12 gegenüber dem Fahrzeuguntergestell 2 festgelegt. Über den Elektromotor 11 werden beide Achsen 7, 8 des Fahrzeugmodells 1 angetrieben. Die Kraftübertragung erfolgt über in Fig. 1 nicht sichtbare Motorwellen 111, 112, die über jeweils ein Getriebe 19, 20 mit den Achsen 7, 8 verbunden sind.In a central region 9 of the vehicle undercarriage 2 an opening 10 is provided obliquely to the longitudinal axis 43, in which an electric motor 11 is arranged. The electric motor 11 is fixed via a torque arm 12 relative to the vehicle undercarriage 2. Both axles 7, 8 of the vehicle model 1 are driven via the electric motor 11. The power transmission takes place via in Fig. 1 invisible motor shafts 111, 112, which are connected via a respective transmission 19, 20 with the axes 7, 8.

Die Motorwellen 111, 112 des Elektromotors 11, die bei einem Glockenläufermotor einstückig sein können, liegen parallel zu einer Mittelebene 48 des Fahrzeuguntergestells 2 und in einem Winkel a schräg zur Längsachse 43 des Fahrzeuguntergestells 2. Die diagonal gegenüberliegenden Eckbereichen 21, 22 des Fahrzeuguntergestells 2 zugeordneten Getriebe 19, 20 sind Schneckengetriebe, mit jeweils einer Schnecke 17, 18 und einem Schneckenrad 44, 45, wobei jede Schnecke 17, 18 über eine flexible Wellenkupplung 15, 16 drehfest mit einer Motorwelle 111, 112 des Elektromotors 11 verbunden ist, während die geradverzahnten Schneckenräder 44, 45 drehfest auf den Achsen 7, 8 befestigt sind. Aufgrund der Schräganordnung der Motorwellen 111, 112 liegen auch die Schnecken 17, 18 jeweils im Winkel a über ihren zugeordneten Schneckenräder 44, 45, so dass letzteres, um einen möglichst spielfreien Eingriff zu gewährleisten, keine Schrägverzahnung aufweisen müssen.The motor shafts 111, 112 of the electric motor 11, which may be integral with a bell rotor motor, are parallel to a center plane 48 of the vehicle undercarriage 2 and at an angle a obliquely to the longitudinal axis 43 of the vehicle undercarriage 2. The diagonally opposite corner regions 21, 22 of the vehicle undercarriage 2 assigned Gears 19, 20 are worm gears, each having a worm 17, 18 and a worm wheel 44, 45, each screw 17, 18 via a flexible shaft coupling 15, 16 rotatably connected to a motor shaft 111, 112 of the electric motor 11, while the spur gears Worm wheels 44, 45 rotationally fixed on the axes 7, 8 are attached. Due to the oblique arrangement of the motor shafts 111, 112 and the worm 17, 18 are each at an angle a on their associated worm gears 44, 45, so that the latter, in order to ensure a backlash-free engagement, must have no helical gearing.

Zwischen den flexiblen Wellenkupplungen 15, 16 und dem Elektromotor 11 ist jeweils eine Schwungmasse 13, 14 angeordnet. Diese sind entweder auf die Motorwellen 111, 112 aufgesteckt und drehfest verschraubt. Die Schwungmassen 13, 14 können aber auch die Motorwellen 111, 112 fortsetzen, so dass die Wellenkupplungen 15, 16 direkt an den Schwungmassen 13, 14 befestigt werden. Denkbar ist auch, die Schwungmassen 13, 14 mit den Motorwellen 111, 112 einstückig auszuführen. Wichtig ist, dass die Schwungmassen 13, 14 gemeinsam mit dem Elektromotor 11 innerhalb der Ausnehmung 10 im Fahrzeuguntergestell 2 liegen, die hierzu mit (nicht näher bezeichneten) Erweiterungen versehen ist.Between the flexible shaft couplings 15, 16 and the electric motor 11 each have a flywheel 13, 14 is arranged. These are either plugged onto the motor shafts 111, 112 and bolted non-rotatably. However, the flywheel masses 13, 14 can also continue the motor shafts 111, 112, so that the shaft couplings 15, 16 are fastened directly to the flywheel masses 13, 14. It is also conceivable, the flywheel masses 13, 14 with the motor shafts 111, 112 in one piece. It is important that the flywheel masses 13, 14 together with the electric motor 11 are within the recess 10 in the vehicle undercarriage 2, which is provided for this purpose with (not designated) extensions.

Die Schnecken 17, 18, die Wellenkupplungen 15, 16 und die Schwungmassen 13, 14 liegen - von oben betrachtet -fluchtend auf einer Linie, insbesondere fluchtend zur Drehachse der Motorwellen 111, 112 des Elektromotors 11, die im Winkel a zur Längsachse 43 des Fahrzeuguntergestells 2 ausgerichtet sind. Bei einem Winkel a von beispielsweise 6,5° oder 7° ergibt sich dadurch innerhalb des Fahrzeuguntergestells 2 eine Diagonalanordnung, d.h. die Elemente 111, 112, 13, 14, 15, 16, 17, 18 verlaufen diagonal von einem Eckbereich 21 zu einem anderen Eckbereich 22 des Fahrzeuguntergestells 2. Die zur Verfügung stehende Länge des Fahrzeugmodells 1 wird dadurch optimal ausgenutzt. Beispielsweise lassen sich dadurch relativ große Schwungmassen 13, 14 einbauen, die für einen gleichmäßigen Lauf der Fahrzeugmodelle 1 sorgen, was insbesondere bei sehr kleinen Maßstäben wichtig ist.The worms 17, 18, the shaft couplings 15, 16 and the flywheels 13, 14 are - viewed from above - aligned on a line, in particular aligned with the axis of rotation of the motor shafts 111, 112 of the electric motor 11 at an angle a to the longitudinal axis 43 of the Vehicle undercarriage 2 are aligned. At an angle a of, for example, 6.5 ° or 7 °, this results in a diagonal arrangement within the vehicle undercarriage 2, ie the elements 111, 112, 13, 14, 15, 16, 17, 18 extend diagonally from one corner region 21 to another Corner 22 of the vehicle undercarriage 2. The available length of the vehicle model 1 is thereby optimally utilized. For example, this makes it possible to install relatively large flywheel masses 13, 14, which ensure uniform running of the vehicle models 1, which is particularly important at very small scales.

Man erkennt in den Fig. 2 und 3, dass die Schnecken 17, 18 der Getriebe 19, 20 nicht nur bezogen auf die Mittelebene 48 des Fahrzeuguntergestells 2 in einem Winkel a schräg zur Längsachse 43 des Fahrzeuguntergestells 2 ausgerichtet sind. Sie liegen zudem in einem Winkel b schräg zur Mittelebene 48 des Fahrzeuguntergestells 2 und greifen infolgedessen von unten her schräg in das jeweils zugeordnete Schneckenrad 44, 45 des Getriebes 19, 20 ein. Die Größe des Winkels b zwischen der Mittelebene 48 des Fahrzeuguntergestells 2 und den Schnecken 17, 18 hängt im Wesentlichen von der Einbautiefe des Elektromotors 11 innerhalb des Durchbruchs 10 ab.One recognizes in the FIGS. 2 and 3 in that the worms 17, 18 of the gearboxes 19, 20 are oriented at an angle a obliquely to the longitudinal axis 43 of the vehicle undercarriage 2, not only relative to the center plane 48 of the vehicle undercarriage 2. They are also at an angle b obliquely to the median plane 48 of the vehicle undercarriage 2 and consequently engage obliquely from below in the respective associated worm wheel 44, 45 of the transmission 19, 20 a. The size of the angle b between the center plane 48 of the vehicle undercarriage 2 and the screws 17, 18 essentially depends on the installation depth of the electric motor 11 within the aperture 10.

Die Schnecken 17, 18 sind jeweils in Lagern 23, 24 drehbar gelagert. Diese sind dabei auf eine Oberseite 25 des Fahrzeuguntergestells 2 aufgeschraubt. In den Lagern 23, 24 sind die Schnecken 17, 18 derartig drehbar gelagert, dass die Drehachsen der Schnecken 17, 18 im Winkel b zur Mittelebene des Fahrzeuguntergestells 2 verlaufen. Dieser Winkel b beträgt beispielsweise zwischen 10° und 25°, in diesem Fall etwa 18°. Im Verhältnis zur Längsachse 43 sind die Schnecken 17, 18 im gleichen Winkel a wie der Elektromotor 11 angeordnet, also beispielsweise in einem Winkel von 6,5°. Durch diese schräge Ausrichtung der Schnecken 17, 18 gegenüber den Schneckenrädern 44, 45 kann auf eine Schrägverzahnung der Schnecken 17, 18 verzichtet werden, da die Schnecken 17,18 entsprechend schräg mit den Schneckenrädern kämmen. Der Winkelversatz zur Drehachse des in dem Durchbruch 10 abgesenkten Elektromotors 11 wird durch die flexiblen Wellenkupplungen 13, 14 ausgeglichen. Dadurch erhält das Fahrzeugmodell 1 eine insgesamt geringe Bauhöhe.The screws 17, 18 are each rotatably mounted in bearings 23, 24. These are screwed onto an upper side 25 of the vehicle undercarriage 2. In the bearings 23, 24, the screws 17, 18 are rotatably mounted such that the axes of rotation of the screws 17, 18 extend at an angle b to the median plane of the vehicle undercarriage 2. This angle b is for example between 10 ° and 25 °, in this case about 18 °. In relation to the longitudinal axis 43, the screws 17, 18 are arranged at the same angle a as the electric motor 11, so for example at an angle of 6.5 °. By this oblique orientation of the screws 17, 18 relative to the worm wheels 44, 45 can be dispensed with a helical toothing of the screws 17, 18, since the worm 17.18 mesh correspondingly obliquely with the worm wheels. The angular offset to the axis of rotation of the lowered in the opening 10 electric motor 11 is compensated by the flexible shaft couplings 13, 14. This gives the vehicle model 1 a total low height.

Der Fahrzeuguntergestell 2 ist beispielsweise plattenförmig ausgebildet und weist für die Aufnahme des Elektromotors 11 mit den Schwungmassen 13, 14 und den Wellenkupplungen 15, 16 den Durchbruch 10 auf. Es ist auch möglich, anstelle eines einteiligen, plattenförmigen Fahrzeuguntergestells 2 ein mehrteiliges Fahrzeuguntergestell vorzusehen, beispielsweise einen Gitterrahmen.The vehicle undercarriage 2 is formed, for example, plate-shaped and has the opening 10 for receiving the electric motor 11 with the flywheel masses 13, 14 and the shaft couplings 15, 16. It is also possible, instead of a one-piece, plate-shaped vehicle undercarriage 2 to provide a multi-part vehicle undercarriage, for example a grid frame.

Zur Stromaufnahme über die Räder 3, 4, 5, 6 sind blattfederartige Stromabnehmer 26, 27, 28, 29 vorgesehen, die an Innenseiten von Spurkränzen 30, 31, 32, 33 unter Vorspannungen anliegen. Die Spurkränze sind dabei an Innenseiten der Räder 3, 4, 5, 6 ausgebildet und dienen dazu, das Fahrzeugmodell entlang der Schienen zu führen.For current consumption via the wheels 3, 4, 5, 6, leaf spring-like current collectors 26, 27, 28, 29 are provided, which abut on inner sides of flanges 30, 31, 32, 33 under biases. The flanges are formed on inner sides of the wheels 3, 4, 5, 6 and serve to guide the vehicle model along the rails.

Zum einfachen Anschließen von Versorgungsleitungen des Elektromotors 11 an die Stromabnehmer 26, 26, 28, 29 weisen diese Anschlusslaschen 34, 35, 36, 37 auf, die über die Oberseite 25 des Fahrzeuguntergestells 2 hervorstehen. Dabei sind die Stromabnehmer 26, 27, 28, 29 in zur Oberseite hin offenen Schlitzen 38, 39, 40, 41 gehalten und damit relativ stabil am Fahrzeuguntergestell 2 befestigt.For easy connection of supply lines of the electric motor 11 to the current collector 26, 26, 28, 29, these connection tabs 34, 35, 36, 37, which protrude beyond the top 25 of the vehicle undercarriage 2. In this case, the current collectors 26, 27, 28, 29 are held in slots open to the top 38, 39, 40, 41 and thus fixed relatively stable on the vehicle undercarriage 2.

In Fig. 2 ist das Fahrzeugmodell 1 in Seitenansicht dargestellt. Es ist zu erkennen, dass der Elektromotor 11 mit den Schwungmassen 13, 14 in einer parallel zu einer Mittelebene 48 des Fahrzeuguntergestells 2 verlaufenen (nicht näher bezeichneten) Ebene liegt, während die Schnecken 17, 18 beziehungsweise deren Drehachsen in einem Winkel b zu dieser Ebene verlaufen. Im dargestellten Ausführungsbeispiel beträgt dieser Winkel 18°. Diese Ausgestaltung ermöglicht es, geradverzahnte Schneckenräder 44, 45 zu verwenden anstelle der sonst im Zusammenhang mit Schneckenradgetrieben üblichen Schrägverzahnungen. Die Schneckenradgetriebe lassen sich damit mit geringerem Aufwand und damit kostengünstiger herstellen. Dennoch kann der Eingriff der Schnecken 17, 18 in die Zahnräder 44, 45 aufgrund der Diagonalanordnung des Antriebsstrangs 111, 112, 13, 14, 15, 16, 17, 18 nahezu spielfrei erfolgen.In Fig. 2 the vehicle model 1 is shown in side view. It can be seen that the electric motor 11 with the flywheels 13, 14 in a plane parallel to a median plane 48 of the vehicle undercarriage 2 (not designated) level, while the screws 17, 18 and their axes of rotation at an angle b to this plane run. In the illustrated embodiment, this angle is 18 °. This embodiment makes it possible to use straight-toothed worm wheels 44, 45 instead of the otherwise commonly used in connection with worm gears helical gears. The worm gear can thus be produced with less effort and thus cheaper. Nevertheless, the engagement of the screws 17, 18 in the gears 44, 45 due to the diagonal arrangement of the drive train 111, 112, 13, 14, 15, 16, 17, 18 take place almost without play.

Durch die Aufnahme des Elektromotors 11 mit den Schwungmassen 13, 14 in dem Durchbruch 10 des Fahrzeuguntergestells 2 ergibt sich eine deutliche Verringerung der Bauhöhe des Fahrzeugmodells 1. Dies wird insbesondere in der Darstellung gemäß Figur 2 deutlich. Dabei stehen der Elektromotor 11 und die Schwungmassen 13, 14 sowohl über eine Oberseite 25 des Fahrzeuguntergestells 2 hervor, als auch über dessen Unterseite. Die Unterseite ist bei dem dargestellten Ausführungsbeispiel offen ausgestaltet, es ist aber auch möglich, den Elektromotor 11 und die Getriebe 13, 14 an der Unterseite abzudecken, falls dies gewünscht oder notwendig ist. Dafür kann der Durchbruch beispielsweise einen (nicht gezeigten) geschlossenen Boden aufweisen.The inclusion of the electric motor 11 with the flywheel masses 13, 14 in the opening 10 of the vehicle undercarriage 2 results in a significant reduction in the height of the vehicle model 1. This is particularly in the illustration according to FIG. 2 clear. In this case, the electric motor 11 and the flywheel masses 13, 14 protrude both over an upper side 25 of the vehicle undercarriage 2, as well as over its underside. The bottom is designed open in the illustrated embodiment, but it is also possible to cover the electric motor 11 and the gear 13, 14 on the underside, if desired or necessary. For example, the breakthrough may have a closed bottom (not shown).

Fig. 3 zeigt das Fahrzeugmodell 1 von einer Unterseite. Deutlich ist zu erkennen, dass die Längsachse 110 des Elektromotors 11 und dessen Motorwellen 111, 112 in einem spitzen Winkel a zur Längsachse 43 verlaufen, der in diesem Ausführungsbeispiel 6,5° beträgt. Der genaue Winkel a ist allerdings von der Länge und Breite des Fahrzeugmodells 1 abhängig. Die Drehmomentstütze 12 ist an der Unterseite 44 des Fahrzeuguntergestells 2 verschraubt, also relativ leicht demontierbar, sodass auch ein Austausch beziehungsweise eine Reparatur des Elektromotors 11 mit relativ geringem Aufwand möglich ist. Fig. 3 shows the vehicle model 1 from a bottom. It can be clearly seen that the longitudinal axis 110 of the electric motor 11 and its motor shafts 111, 112 extend at an acute angle a to the longitudinal axis 43, which in this embodiment is 6.5 °. The exact angle a, however, depends on the length and width of the vehicle model 1. The torque arm 12 is screwed to the bottom 44 of the vehicle undercarriage 2, so relatively easy to disassemble, so that an exchange or repair of the electric motor 11 is possible with relatively little effort.

Fig. 3 ist darüber hinaus zu entnehmen, dass die Schneckenräder 44, 45 der Schneckenradgetriebe 19, 20 in Ausnehmungen 46, 47 des Fahrzeuguntergestells aufgenommen sind, die sich in den Eckbereichen 21, 22 befinden und die zu einer Längsseite des Fahrzeuguntergestells 2 hin offen sind. In den Ausnehmungen 46, 47 liegen die Schneckenräder 44, 45, die folglich nicht mittig auf den Achsen 7, 8 angeordnet sind, sondern jeweils zu einem Ende der Achsen hin versetzt, sodass eine diagonale Lagerung des Elektromotors 11 ermöglicht wird. Durch die Ausnehmungen 46, 47 benötigen die Schneckenräder 44, 45 kaum zusätzlichen Bauraum, sodass die kompakte Bauweise des Fahrzeugmodells 1 erhalten bleibt. Ferner schafft die Diagonalanordnung zusätzlichen Platz im Bereich der Achsen 7, 8, um beispielsweise einen Mittelleiter einbauen zu können. Fig. 3 In addition, it can be seen that the worm wheels 44, 45 of the worm gear 19, 20 are received in recesses 46, 47 of the vehicle undercarriage, which are located in the corner regions 21, 22 and which are open to a longitudinal side of the vehicle undercarriage 2 out. In the recesses 46, 47 are the worm wheels 44, 45, which are therefore not centrally located on the axes 7, 8, but each offset to one end of the axes, so that a diagonal mounting of the electric motor 11 is made possible. Through the recesses 46, 47, the worm wheels 44, 45 require little additional space, so that the compact design of the vehicle model 1 is maintained. Furthermore, the diagonal arrangement creates additional space in the region of the axes 7, 8 in order, for example, to be able to install a center conductor.

Das erfindungsgemäße Fahrzeugmodell 1 weist also einen winkelig bezüglich der Längsachse 43 angeordneten Elektromotor 11 auf, der mittig zwischen den angetriebenen Achsen 7, 8 angeordnet ist und dabei innerhalb eines Durchbruchs 10 des Fahrzeuguntergestells 2 aufgenommen ist, also nach unten versetzt ist. Damit ergibt sich ein sehr kompakter Aufbau des Fahrzeugmodells 1, das damit eine gute Basis für unterschiedlichste Aufbauten bildet, die selbst keinen oder nur einen geringen Raum für einen Elektromotor 11 aufweisen. Auch bei sehr kleinen Maßstäben ist damit eine maßstabsgetreue Nachbildung möglich.The vehicle model 1 according to the invention thus has an angularly arranged with respect to the longitudinal axis 43 electric motor 11 which is arranged centrally between the driven axles 7, 8 and is received within an opening 10 of the vehicle undercarriage 2, that is offset downwards. This results in a very compact design of the vehicle model 1, which thus forms a good basis for a variety of structures that have no or only a small space for an electric motor 11 itself. Even with very small scales, a true-to-scale reproduction is possible.

Die Erfindung ist nicht auf eine der geschilderten Ausführungsbeispiele beschränkt, sondern in vielfältiger Weise abwandelbar. So können die Wellenkupplungen 15, 16 einstückig mit den Motorwellen 111, 112 sein, indem letztere zumindest abschnittsweise flexibel ausgebildet sind. Diese flexiblen Abschnitte 15, 16 der Motorwelle 111, 112 liegen dann jeweils zu beiden Seiten des Elektromotors 11 zwischen den Schwungmassen 13, 14 und den Schnecken 17, 18, so dass die Schwungmassen 13, 14 und die Schnecke 17, 18 jeweils drehfest miteinander verbunden sind. Der Winkel b zwischen der Mittelebene 48 des Fahrzeuguntergestells 2 und den Schnecken 17, 18 hängt auch hier im Wesentlichen von der Lage des Elektromotors 11 innerhalb des Durchbruchs 10 ab.

Thus, the shaft couplings 15, 16 may be integral with the motor shafts 111, 112, by the latter being at least partially flexible. These flexible portions 15, 16 of the motor shaft 111, 112 are then respectively on both sides of the electric motor 11 between the flywheels 13, 14 and the screws 17, 18, so that the flywheel masses 13, 14 and the screw 17, 18 rotatably connected to each other are. The angle b between the median plane 48 of the vehicle undercarriage 2 and The worm 17, 18 here depends essentially on the position of the electric motor 11 within the aperture 10 from. <B> LIST OF REFERENCES </ b> 1 vehicle model 34 flap 2 Vehicle undercarriage 35 flap 3 wheel 36 flap 4 wheel 37 flap 5 wheel 38 slot 6 wheel 39 slot 7 axis 40 slot 8th axis 41 slot 9 Middle area 42 axis of rotation 10 breakthrough 43 longitudinal axis 11 electric motor 44 worm 12 torque arm 45 worm 13 Inertia 46 recess 14 Inertia 47 recess 15 flexible section / shaft coupling 48 midplane 16 flexible section / shaft coupling 110 longitudinal axis 17 slug 111 motor shaft 18 slug 112 motor shaft 19 transmission 20 transmission 21 corner 22 corner 23 bearing housing 24 bearing housing 25 top 26 pantograph 27 pantograph 28 pantograph 29 pantograph 30 flange 31 flange 32 flange 33 flange
