Description

Die Erfindung betrifft eine Hängebahn, insbesondere Einschienen-Elektrohängebahn, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a monorail, in particular monorail monorail, according to the preamble of claim 1.

Aus der deutschen Offenlegungsschrift DE 196 10 118 A1 ist bereits eine Hängebahn mit einem entlang einer Profilschiene geführten Fahrwerk bekannt. Das Fahrwerk besteht im wesentlichen aus einem Rahmen und einem über ein an dem Rahmen angeordneten Elektromotor antreibbaren Laufrad. Das Laufrad läuft auf der oberen Lauffläche der Profilschiene ab, zu der wenigstens in den von der horizontalen abweichenden Bereichen parallel hierzu Zusatzschienen verlaufen. An diesen Zusatzschienen laufen Reibräder ab, die im direkten Kontakt mit der Lauffläche des Laufrades stehen und zur Erhöhung des Anpressdruckes des Laufrades auf die Lauffläche der Profilschiene und als zusätzliche Antriebselemente dienen. Hierzu sind zwei Reibräder vorgesehen, die jeweils in Fahrtrichtung gesehen vor und hinter der Achse des Laufrades und von oben dem Laufrad zugeordnet sind. Die Reibräder werden jeweils über Kniehebel mit einem Scharniergelenk an dem Rahmen gehalten und sind zusätzlich über eine ihre Achsen aufnehmende Verbindungsstange miteinander verbunden. Die Verbindungsstange ist hierbei oberhalb des Laufrades und in Fahrtrichtung verlaufend angeordnet. Die Achsen der Reibräder sind in Fahrtrichtung verschiebbar in der Verbindungsstange gelagert, um den Reibrädern die Möglichkeit zu geben, bei Toleranzen des Abstandes zwischen der Oberfläche der Profilschiene und der Zusatzschiene durch eine Bewegung aufeinander zu oder voneinander weg diese Toleranzen auszugleichen. Hierbei wird gleichzeitig eine Aufrechterhaltung der Anpreßkraft des Laufrades auf die Oberfläche der Profilschiene und der Reibräder auf die Zusatzschiene gewährleistet. Um dies zu erreichen, sind die Achsen der Hilfsräder in der Verbindungsstange über ein Federelement zueinander beaufschlagt. Desweiteren sind die Hebel des L-förmigen Kniegelenkes über Feder- bzw. Dämpfungselemente miteinander verbunden, um Schwingungen oder Vibrationen der Reibräder beim Ablaufen entlang der Zusatzschiene zu vermeiden. Auch soll hierdurch ein sicheres Anliegen der Hilfsräder am Laufrad für eine Vergleichmäßigung der Anpreßkraft in sämtlichen Streckabschnitten sorgen.A monorail is already known from German published patent application DE 196 10 118 A1 known with a running along a profile rail. The chassis consists essentially of a frame and one over one on the frame arranged electric motor driven impeller. The impeller runs on the upper one Running surface of the profile rail, at least in the from the horizontal deviating areas run parallel to this additional rails. On this Additional rails run off friction wheels that are in direct contact with the tread of the Stand impeller and to increase the contact pressure of the impeller on the Running surface of the profile rail and serve as additional drive elements. For this are two friction wheels are provided, each seen in the direction of travel in front of and behind the Axis of the impeller and from above are assigned to the impeller. The friction wheels are held on the frame by toggle levers with a hinge joint and are also via a connecting rod that receives their axes connected with each other. The connecting rod is above the impeller and arranged in the direction of travel. The axes of the friction wheels are in Direction of travel slidably mounted in the connecting rod to the friction wheels Possibility to give tolerance to the distance between the surface of the Profile rail and the additional rail by moving towards or away from each other to compensate for these tolerances. Here is a Maintaining the contact pressure of the impeller on the surface of the profile rail and the friction wheels on the additional rail guaranteed. To achieve this, they are Axes of the auxiliary wheels in the connecting rod to each other via a spring element applied. Furthermore, the levers of the L-shaped knee joint are or damping elements connected to each other to oscillations or vibrations to avoid the friction wheels when running along the additional rail.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Hängebahn, insbesondere Einschienen-Elektrohängebahn, zu schaffen, deren angetriebenes Fahrwerk bei gleichzeitig konstruktiv einfacher Bauweise verbesserte Traktionseigenschaften aufweist und daher insbesondere zum Einsatz in Steigungsund Gefällestrecken einsetzbar ist.The present invention has for its object a monorail, especially monorail monorail, to create their driven Improved chassis with a structurally simple design Has traction properties and is therefore particularly suitable for use in inclines and Slope is usable.

Diese Aufgabe wird bei einer Hängebahn, insbesondere Einschienen-Elektrohängebahn, durch die im Anspruch 1 aufgeführten Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 bis 10 angegeben.This task is performed on a monorail system, especially a monorail monorail system, solved by the features listed in claim 1. Advantageous embodiments of the invention are in subclaims 2 to 10 specified.

Erfindungsgemäß wird durch die Zusammenfassung der Reibräder, des Verbindungselementes und des Federelementes, von dem die Reibräder zueinander federnd beaufschlagt werden, zu einer Baueinheit, die reitend von oben auf das Laufrad des Fahrwerks der Hängebahn aufgelegt werden kann, im Zusammenhang mit den mindestens teilweise und weitestgehend parallel und mit Abstand zur Schiene für das Laufrad angeordneten Zusatzschiene ein kompakter und konstruktiv einfacher Aufbau eines schienenverfahrbaren Fahrwerkes geschaffen, mit dem auch Steigungsund Gefällestrecken sowie ein Anfahren und Abbremsen mit hohen Lasten bewältigt werden kann. Durch die Zusammenfassung der für eine Reibschlußverstärkung eines Laufrades erforderlichen Bauteile zu einer Baueinheit ist es auch einfach möglich, bereits bestehende Fahrwerke von Hängebahnen nachzurüsten. Um die Baueinheit mit den Reibrädern auch außerhalb der Bereiche mit den parallel zu der Schiene verlaufenden Zusatzschienen in seiner auf dem Laufrad reitenden Position zu halten sowie in Bereichen mit der Zusatzschiene seitlich zu führen, ist vorgesehen, das Verbindungselement über ein Bolzenelement an dem Rahmen des Fahrwerks in einem dort angeordneten Führungsteil mit einer bogenförmigen Öffnung zu führen. Diese bogenförmige Führung weist eine Krümmung mit einem Kreisradius auf, dessen Mittelpunkt die Laufachse des Laufrades ist. Somit ist gewährleistet, daß die Baueinheit aus den Reibrädern, dem Verbindungselement und dem Federelement sich in Abhängigkeit von dem zur Verfügung stehenden Abstand zwischen der Oberfläche der Schiene und der Innenfläche der Zusatzschiene um die Achse des Laufrades in einem vorgesehenen Bereich bewegen können. Das Bolzenelement ist vorzugsweise an einer in Fahrtrichtung des Fahrwerks gesehen sich über das vordere Reibrad hinausersteckenden Verlängerung des Verbindungselementes angeordnet. Hierdurch ergibt sich eine schleppende und somit auf dem Laufrad selbstführende Anordnung der Reibräder mit dem Verbindungselement.According to the summary of the friction wheels, the Connecting element and the spring element from which the friction wheels to each other be resiliently applied to a unit that rides from above on the Impeller of the suspension of the monorail can be placed in the context with the at least partially and largely parallel and at a distance from the rail for the impeller arranged additional rail a compact and structurally simple Construction of a rail-traveling undercarriage created, with which incline and Descended as well as starting and braking with high loads can be. By combining the for a frictional reinforcement Components required to form a structural unit, it is also easily possible to retrofit existing trolleys from monorails. To the unit with the friction wheels also outside the areas with the parallel to the rail keep running additional rails in their riding position on the wheel and in areas with the additional rail to the side, it is intended that Connecting element via a bolt element on the frame of the chassis in one guide part arranged there with an arcuate opening. This arcuate guide has a curvature with a circular radius, the The center point is the axis of the impeller. This ensures that the Unit from the friction wheels, the connecting element and the spring element itself depending on the available distance between the surface the rail and the inner surface of the additional rail around the axis of the impeller in can move a designated area. The bolt element is preferred at one seen in the direction of travel of the chassis over the front friction wheel extending extension of the connecting element arranged. hereby this results in a sluggish and thus self-guiding arrangement on the impeller the friction wheels with the connecting element.

Desweiteren erweist sich als vorteilhaft, daß die Baueinheit nur begrenzt auf dem Laufrad verschwenkbar ist und zwar aus seiner Ruhestellung, in der das in Fahrtrichtung gesehen vordere Reibrad auf einem Niveau unterhalb der Vorderkante des Anfang der Zusatzschiene liegt, in eine Betriebsstellung schwenkbar ist, in der beide Reibräder im Kontakt mit dem Laufrad und der Zusatzschiene sind. Die Winkellage des Verbindungselementes in seiner Betriebstellung ist hierbei abhängig von dem Abstand zwischen der Lauffläche der Schiene und der Zusatzschiene. Durch die nach vorne geneigte Anordnung des vorderen Reibrades und des Verbindungselementes in seiner Ruhestellung ist ein besonders sanfter und einfacher Einlauf des steigungsfähigen Fahrwerkes in den Streckabschnitt mit einer Zusatzschiene möglich. Die Reibschlußverstärkung wird dadurch erreicht, daß das in Fahtrichtung gesehen hintere Rad im Gegensatz zu dem vorderen Rad sich in der Ruhestellung in einem angehobenen Zustand befindet und somit nach Kontakt mit dem Anfang der Zusatzschiene nach unten entlang des Laufrades verschoben wird und somit das vordere Laufrad in Richtung der Zusatzschiene zunächst anhebt und dann andrückt. Die bogenförmige Öffnung gestattet eine Verschwenkung der Baueinheit aus Reibrädern, Verbindungselement und Federelement zwischen der Ruhe- und der Betriebsstellung und innerhalb der Betriebsstellung.Furthermore, it proves to be advantageous that the unit is limited to the Impeller is pivotable, namely from its rest position, in which the Driving direction seen front friction wheel at a level below the front edge the beginning of the additional rail is pivotable into an operating position in which both friction wheels are in contact with the impeller and the additional rail. The The angular position of the connecting element in its operating position is dependent on this on the distance between the running surface of the rail and the additional rail. Due to the forward inclined arrangement of the front friction wheel and the Connecting element in its rest position is a particularly gentle and simple Entry of the inclinable undercarriage into the stretch section with a Additional rail possible. The frictional reinforcement is achieved in that the Driving direction seen in the rear wheel as opposed to the front wheel in the Rest position is in a raised state and thus after contact with the beginning of the additional rail is moved down along the impeller and thus first raises the front wheel in the direction of the additional rail and then presses. The arc-shaped opening allows the Assembly of friction wheels, connecting element and spring element between the Rest and operating position and within the operating position.

Vorteilhafterweise ist an dem Verbindungselement im Bereich des in Fahrtrichtung gesehen vorderen Reibrades ein zusätzliches Gewicht angeordnet bzw. die Baueinheit derart austariert, daß während der Fahrt des Fahrwerkes entlang von Streckenabschnitten ohne Zusatzschienen das vordere Reibrad sich in einer nach unten geneigten Stellung entsprechend seiner Ruhestellung befindet. Diese Lage des vorderen Reibrades kann auch durch ein zusätzliches zwischen dem Verbindungselement und dem Rahmen des Fahrwerks angreifendes Federelement bewerkstelligt werden. It is advantageous on the connecting element in the region of the direction of travel seen front friction wheels arranged an additional weight or the unit so balanced that while the undercarriage is moving along Route sections without additional rails the front friction wheel in one after downward inclined position is according to its rest position. This location of the front friction wheels can also be added by an additional between the Connecting element and the spring element engaging the frame of the chassis be accomplished.

In einer bevorzugten Ausführungsform ist das Verbindungselement aus einem Schwingen- und einem Winkelteil und somit zweiteilig ausgebildet. Die beiden Teile sind über eine Schwenkachse, die parallel zur Laufachse des Laufrades ausgerichtet ist, miteinander verbunden und das der Schwenkachse gegenüberliegende Ende des Winkelteils ist mit dem Schwingenteil verbunden. Das Schwingenteil ist bogenförmig ausgebildet, das Winkelteil ist an einem Ende des Schwingenteils gelagert und hierbei das freie Ende des Winkelteils wiederum in Richtung des anderen Ende des Schwingenteils gerichtet. Damit nur eine begrenzte Beweglichkeit des Winkelteils gegenüber dem Schwingenteil möglich ist, die für den Ausgleich der Toleranzen bezüglich des Abstandes zwischen der Zusatzschiene und der Lauffläche der Schiene in der Betriebsstellung erforderlich ist, ist eine Führung des Winkelteils gegenüber dem Verbindungsteil über eine Stift-Langlochverbindung vorgesehen. Das Langloch ist hierbei an dem der Schwenkachse des Winkelteils gegenüberliegenden Ende des Winkelteils angeordnet und der Stift im Bereich der Mitte des Schwingenteils. Die Reibräder sind hierbei um quer zur Fahrtrichtung und parallel zur Achse des Laufrades ausgerichtete Achsen jeweils an der Mitte des Winkelteils und an dem in Fahrtrichtung gesehen vorderen Ende des Schwingenteils gelagert. Hierduch ist gewährleistet, daß auch bei Abstandsänderungen zwischen der Lauf- und Zusatzschiene die Reibräder und das Laufrad zur Übertragung der Antriebskräfte auf die Schienen gepresst werden.In a preferred embodiment, the connecting element is made of a Swing and an angle part and thus formed in two parts. The two parts are aligned via a swivel axis that is parallel to the running axis of the impeller is connected to each other and the opposite end of the pivot axis Angle part is connected to the swing arm. The swing arm is arched formed, the angular part is mounted on one end of the rocker part and here the free end of the angle part in turn towards the other end of the Swing part directed. So only a limited mobility of the angle part compared to the swing arm part is possible for the compensation of the tolerances regarding the distance between the additional rail and the running surface of the rail is required in the operating position, a guide of the angular part relative to the Connection part provided via a pin-slot connection. The elongated hole is here at the end of the pivot axis of the angular part opposite Angular part arranged and the pin in the area of the center of the swing arm. The Friction wheels are at right angles to the direction of travel and parallel to the axis of the wheel Aligned axes at the center of the angular part and at the direction of travel seen front end of the swing arm mounted. This ensures that the friction wheels even when the distance between the running and additional rails changes and the impeller is pressed onto the rails to transmit the driving forces become.

Eine derartige Ausbildung des Fahrwerkes mit einer Reibschlußverstärkung des Laufrades über ein als Baueinheit ausgebildetes Verbindungselement mit Reibrädern eignet sich bevorzugt für den Einsatz von Einschienen-Elektrohängebahnen, die eine I-förmig ausgebildete Schiene aufweisen, auf deren Oberflansch das Laufrad abläuft und an dem Rahmen des Fahrwerks um vertikale Achsen drehbare Führungsrollen zur seitlichen Führung des Fahrwerks entlang der Flansche der Schiene angeordnet sind. Derartige Fahrwerke werden verwendet, um hieran Lastaufnahmemittel aufzuhängen, um beispielsweise Automobilteile zwischen einzelnen Fertigungsstationen zu transportieren. Bei diesen Fahrwerken sind die Lastaufnahmemittel mit einer Lasttraverse versehen, die um eine vertikale Achse schwenkbar mit dem angetriebenen Fahrwerk verbunden sind und an ihrem anderen Ende über eine weitere vertikale Achse mit einem antriebslosen Fahrwerk gelagert sind. Dieses antriebslose Fahrwerk weist ebenfalls Führungsrollen und ein nicht angetriebenes Tragrad auf. Das aus den beiden Fahrwerken und den Lastaufnahmemittel gebildete Schienenfahrzeug ermöglicht eine Durchfahrung von Vertikalbögen der Schienenstrecke bis zu einer Neigung der vertikalen Achse einer gedachten zur Schienenoberfläche senkrecht stehenden Achse von etwa 10°, da die Reibräder sich entsprechend um das Laufrad bewegen können und der Rahmen der Fahrwerke sowie die Lasttraverse ausreichend Abstand zur Schiene einhalten.Such a design of the chassis with a frictional reinforcement Impeller via a connecting element designed as a structural unit with friction wheels is particularly suitable for the use of monorail monorails that are I-shaped have trained rail on whose upper flange the impeller runs and on the frame of the undercarriage rotatable guide rollers for vertical axes lateral guidance of the chassis along the flanges of the rail are arranged. Such trolleys are used to hang load suspension devices from them, for example to close automotive parts between individual production stations transport. With these trolleys, the load suspension devices are with a Load beam provided that can be pivoted about a vertical axis with the powered undercarriage are connected and at their other end via a further vertical axis with a driveless chassis are mounted. This driveless chassis also has guide rollers and a non-driven Carrying wheel on. That formed from the two trolleys and the load handler Rail vehicle allows vertical arches to pass through Rail line up to an inclination of the vertical axis of an imaginary one Rail surface perpendicular axis of about 10 ° because the friction wheels accordingly can move around the wheel and the frame of the trolleys as well keep the load crossbar a sufficient distance from the rail.

Der C-förmig die Schiene 5 seitlich um greifende Rahmen 6 dient ebenfalls zur Aufnahme von Führungsrollen 7, die um senkrechte Achsen drehbar gelagert sind und an den Seitenflächen des Oberflansches 4 der Schiene 5 ablaufen. An dem dem Laufrad 3 abgewandten Ende des Rahmens 6 ist eine ebenfalls vertikalverlaufende Achse 8a gelagert, die Bestandteil eines Lastaufnahmemittels 9 ist.Figure 1 shows a side view of a monorail according to the invention in Version as a monorail overhead conveyor. The monorail consists of essentially from a chassis 1 with a drive designed as an electric motor 2 that can be moved via an impeller 3 on the upper flange 4 of an I-shaped rail 5 is. Here, the drive 2 and the impeller 3 are together via a frame 6 connected. The C-shaped rail 5 laterally around gripping frame 6 also serves for receiving guide rollers 7, which are rotatably mounted about vertical axes and run on the side surfaces of the upper flange 4 of the rail 5. On that Impeller 3 facing away from the end of the frame 6 is also a vertical one Axis 8a mounted, which is part of a load handling device 9.

Das Lastaufnahmemittel 9 weist eine Längstraverse 10 auf, die in Fahrtrichtung F mit Ihrer Längserstreckung verläuft und mit Ihrem einen Ende mit der Achse 8a verbunden ist. Das gegenüberliegende Ende der Längstraverse 10 ist über eine weitere Achse 8b, die ebenfalls vertikal verläuft, mit einem zweiten Fahrwerk 11 verbunden. Das Fahrwerk 11 weißt ebenfalls einen C-förmigen Rahmen 6 auf, an dem ebenfalls Führungsrollen 7 sowie ein um eine quer zur Fahrtrichtung und horizontal verlaufende Achse drehbares Tragrad 12 gelagert sind. Das Tragrad 12 ist gegenüber dem Laufrad 3 nicht angetrieben. Die beiden Fahrwerke 1 und 11, die über die Achsen 8a und 8b sowie die Längstraverse 10 miteinander verbunden sind, bilden ein Fahrzeug 13 an dem beispielsweise in einem Automobilwerk Automobilteile zwischen einzelnen Fertigungsstationen hängend transportiert werden können.The load suspension device 9 has a longitudinal cross member 10, which extends in the direction of travel F. Your longitudinal extension runs and connected at one end to the axis 8a is. The opposite end of the longitudinal cross member 10 is via a further axis 8b, which also runs vertically, connected to a second chassis 11. The Chassis 11 also has a C-shaped frame 6, on which also Guide rollers 7 and one around a transverse to the direction of travel and horizontal Axle rotatable support wheel 12 are mounted. The support wheel 12 is opposite the impeller 3 not driven. The two trolleys 1 and 11, which are on the axes 8a and 8b and the longitudinal cross member 10 are connected to one another, form a vehicle 13 that, for example, in an automobile plant, automobile parts between individuals Manufacturing stations can be transported hanging.

Die durch die Schiene 5 gebildeten Förderstrecken für derartige Fahrzeuge 13 verlaufen nicht nur geradlinig sondern weisen auch Horizontal- und Vertikalbögen auf. Um ein sicheres Anfahren und Abbremsen der Fahrzeuge mit schwerer Last zu ermöglichen und auch ein Durchfahren von Steigerungs- und Gefällestrecken, ist eine Reibschlußverstärkung des Laufrades 3 und ein zusätzlicher Antrieb des Fahrwerk 1 über an einer Zusatzschiene 14 ablaufende Reibräder 15 vorgesehen. Diese Reibschlußverstärkung erfolgt über eine oberhalb und mit Abstand zu dem Oberflansch 4 der Schiene 5 angeordnete Zusatzschiene 14, die mit zwei auf dem Laufrad 3 reitend angeordneten Reibrädern 15 zusammenwirkt. Im Bereich der Zusatzschiene 14 laufen die beiden Reibräder 15 an der Unterseite der Zusatzschiene 14 ab und pressen somit das Laufrad 3 zusätzlich auf die Lauffläche des Oberflansches 4 der Schiene 5 und werden über die Gegenkraft und eine Art Keilwirkung auch gegen die Zusatzschiene 14 gepresst.The conveyor lines formed by the rail 5 for such vehicles 13 not only run in a straight line but also have horizontal and vertical arches. To safely start and brake the vehicles with heavy loads enabling and also driving up and down gradients is one Frictional reinforcement of the impeller 3 and an additional drive for the chassis 1 Provided via friction wheels 15 running on an additional rail 14. This Frictional reinforcement takes place above and at a distance from the Upper flange 4 of the rail 5 arranged additional rail 14 with two on the Impeller 3 mounted friction wheels 15 cooperates. In the field of Additional rail 14, the two friction wheels 15 run on the underside of the additional rail 14 and thus press the impeller 3 additionally on the tread of the Upper flange 4 of the rail 5 and are over the counterforce and a kind Wedge action also pressed against the additional rail 14.

Damit die Reibräder 15 eine derartige Kraft auf das Laufrad 3 und die Zusatzschiene 14 ausüben können, sind diese über quer zur Fahrrichtung F und horizontal verlaufende Achsen an einem gemeinsamen Verbindungselement 16 gelagert. Das Verbindungselement 16 ist zweiteilig aufgebaut und besteht aus einem Schwingenteil 17 und einem Winkelteil 18. Das Schwingenteil 17 ist von der Seite gesehen bogenförmig ausgebildet und an dessen in Fahrtrichtung F gesehen vorderen Ende ist das vordere Reibrad 15v gelagert. An dem dem vorderen Reibrad 15v gegenüberliegenden Ende des Schwingenteils 17 ist über eine Achse 19 ein Ende eines Schenkels des Winkelteils 18 gelagert. Die beiden Schenkel des Winkelteils 18 sind in etwa rechtwinkelig zueinander angeordnet und im Verbindungsbereich der beiden Schenkel ist das in Fahrtrichtung F gesehen hintere Reibrad 15h gelagert. An dem der Achse 19 abgewandten Ende des Winkelteils 18 ist ein parallel zur Laufachse 20 des Laufrades 3 verlaufender Stift 21 befestigt. Der Stift 21 ist in einem Langloch 22 geführt, das etwa in der Mitte des Schwingenteils 17 angeordnet ist (siehe Figur 2). Durch die Führung des Stiftes 21 in dem Langloch 22 ist der Abstand zwischen den beiden Reibrädern 15 in einem vorbestimmten Bereich verstellbar. Dieser Bereich ist so gewählt, daß die möglichen Toleranzen zwischen der Lauffläche des Oberflansches 4 der Schiene 5 und der inneren Lauffläche der Zusatzschiene 14 dadurch ausgeglichen werden können, daß die in Fahrtrichtung F gesehen vorne und hinten auf dem Laufrad 3 abrollenden Reibräder 15 sich aufeinander zu und voneinander weg bewegen können. Hierdurch ändert sich in Fahrtrichtung F gesehen der Abstand zwischen den Reibrädern 15 und somit auch deren Lage in Bezug auf die Laufachse 20 des Laufrades 3. Um den ständigen Kontakt der Reibrädern 15 auf der Oberfläche des Laufrades 3 und der Zusatzschiene 14 zu gewährleisten, sind das Schwingenteil 17 und das Winkelteil 18 über ein Federelement 23 gegeneinander vorgespannt. Das Federelement 23 greift hierzu an einem Ende an dem Stift 21 an und an dem anderen Ende über eine Schraubverbindung 24 an dem Schwingenteil 17 angrenzend an das vordere Reibrad 15v.So that the friction wheels 15 such a force on the impeller 3 and the additional rail 14 can exercise, these are transverse to the direction of travel F and horizontal extending axes mounted on a common connecting element 16. The Connecting element 16 is constructed in two parts and consists of a rocker part 17 and an angle part 18. The rocker part 17 is seen from the side is arcuate and is at the front end seen in the direction of travel F. the front friction wheel 15v stored. On the front friction wheel 15v opposite end of the rocker part 17 is an end via an axis 19 a leg of the angle part 18 is mounted. The two legs of the angle part 18 are arranged approximately at right angles to each other and in the connection area The rear friction wheel 15h is seen in the direction of travel F on both legs. On the end of the angle part 18 facing away from the axis 19 is parallel to the running axis 20 of the impeller 3 extending pin 21 attached. The pin 21 is in an elongated hole 22 guided, which is arranged approximately in the middle of the rocker part 17 (see Figure 2). By guiding the pin 21 in the slot 22, the distance between the two friction wheels 15 adjustable in a predetermined range. That area is chosen so that the possible tolerances between the tread of the upper flange 4 of the rail 5 and the inner tread of the additional rail 14 thereby can be compensated for that seen in the direction of travel F in front and behind the wheels 3 rolling friction wheels 15 towards and away from each other can move. As a result, the distance changes in the direction of travel F. between the friction wheels 15 and thus also their position with respect to the barrel axis 20 of the impeller 3. To ensure constant contact of the friction wheels 15 on the surface to ensure the impeller 3 and the additional rail 14, the swing arm 17 and the angle part 18 biased against each other via a spring element 23. The For this purpose, spring element 23 engages on pin 21 at one end and on the other End via a screw connection 24 on the rocker part 17 adjacent to the front friction wheel 15v.

In der Figur 2 ist eine Ausschnittsvergrößerung von Figur 1 aus dem Bereich des Laufrades 3 und der Reibräder 15 dargestellt. Es ist ersichtlich, daß das Schwingenteil 17 über das vordere Reibrad 15v hinaus verlängert ist und ein quer zur Fahrtrichtung F verlaufendes Bolzenelement 25 aufweist, das in eine bogenförmige Öffnung 26 eingreift. Diese bögenförmige Öffnung 26 ist in einem an dem Rahmen 6 befestigten blechförmigen Tragelement 27 angeordnet und deren Krümmung kann durch einen Kreisbogenabschnitt beschrieben werden, wobei der Radius des Kreisbogens im Mittelpunkt der Laufachse 20 des Laufrades 3 seinen Ursprung hat. Durch die Verbindung des Schwingenteils 18 über das Bolzenelement 25 mit der Öffnung 26 ist gewährleistet, daß in Bereich der Schienen 5 ohne Zusatzschienen 14 die aus den Reibrädern 15, dem Verbindungselement 16 und dem Federelement 23 bestehende Baueinheit auf dem Laufrad 3 reitend gehalten und seitlich geführt wird. Da die zuvor beschriebene Baueinheit über das Bolzenelement 25 in Fahrtrichtung F gesehen schleppend an dem Rahmen 6 geführt wird, haben die Reibräder 15 die Möglichkeit sich auf dem Laufrad 3 selbsttätig zu zentrieren.FIG. 2 shows an enlarged detail of FIG. 1 from the area of the Impeller 3 and the friction wheels 15 shown. It can be seen that the swing arm 17 is extended beyond the front friction wheel 15v and a transverse to the direction of travel F has extending bolt element 25, which in an arcuate opening 26th intervenes. This arcuate opening 26 is attached to the frame 6 in a plate-shaped support element 27 arranged and the curvature can by a Circular arc section are described, the radius of the circular arc in The center of the axis 20 of the impeller 3 has its origin. Through the Connection of the rocker member 18 via the bolt member 25 with the opening 26 ensures that in the area of the rails 5 without additional rails 14 from the Friction wheels 15, the connecting element 16 and the spring element 23 existing Unit held mounted on the impeller 3 and guided laterally. Since the previous one described unit seen over the bolt member 25 in the direction of travel F. is dragged on the frame 6, the friction wheels 15 have the possibility to center itself on the impeller 3.

Desweiteren hat die Öffnung 26 die Aufgabe, eine Verschwenkbewegung der Baueinheit um das Laufrad 3 zu ermöglichen. Diese Verschwenkbewegung findet zwischen einer Ruhe- und einer Betriebsstellung der Baueinheit statt. In der Ruhestellung ist das vordere Reibrad 15v relativ zur Lauffläche des Oberflansches 4 gesehen auf einer Höhe angeordnet, daß zwischen der Zusatzschiene 14 und der Oberseite des Reibrades 15v ein Spalt verbleibt. Hierdurch ist ein sanftes und berührungsloses Einfahren des Reibrades 15v in den Bereich der Schiene 5 mit einer Zusatzschiene 14 möglich. In dieser Ruhestellung liegt das Bolzenelement 25 an dem unteren Ende der bogenförmigen Öffnung 26 auf. Diese Ruhestellung des vorderen Reibrades 15v wird durch eine Austarierung der Baueinheit aus Verbindungselement 16 und Reibrädern 15 in der Weise erreicht, daß der Schwerpunkt in Richtung des vorderen Reibrades 15v verschoben ist. Hierzu sind im Bereich des vorderen Endes des Schwingenteiles 17 zwei Gewichtselemente 28 angeordnet (siehe Figur 3). Grundsätzlich ist es auch möglich, die Baueinheit durch ein zusätzliches Federelement in der Ruhestellung zu halten.Furthermore, the opening 26 has the task of pivoting the Unit to enable the impeller 3. This pivoting movement takes place between a rest and an operating position of the unit instead. In the The front friction wheel 15v is in the rest position relative to the running surface of the upper flange 4 seen arranged at a height that between the additional rail 14 and A gap remains on the top of the friction wheel 15v. This is a gentle and non-contact entry of the friction wheel 15v into the area of the rail 5 with a Additional rail 14 possible. In this rest position, the bolt element 25 is on the lower end of the arcuate opening 26. This rest position of the front Friction wheels 15v are created by balancing the assembly from the connecting element 16 and friction wheels 15 reached in such a way that the focus in the direction of front friction wheel 15v is shifted. These are in the area of the front end the rocker part 17 two weight elements 28 arranged (see Figure 3). In principle, it is also possible to add an additional spring element to the structural unit to keep at rest.

Gleichzeitig ist in der Ruhestellung das hintere Reibrad 15h relativ zur Lauffläche der Schiene 5 gesehen auf einem Niveau angeordnet, so daß die Oberfläche des hinteren Reibrades 15h beim Einfahren des Fahrwerkes 1 in einen Abschnitt der Schiene 5 mit einer Zusatzschiene 14 mit einem abgeschrägten oder als Einlauftrichter ausgebildeten Anfangsabschnitt in Kontakt tritt und anschließend nach unten und zwischen die innere Fläche der Zusatzschiene 14 und der Schiene 5 gedrückt wird. Durch diesen Vorgang des Nachuntendrückens des hinteren Reibrades 15h , wobei auch gleichzeitig dieses Reibrad 15h relativ zum Laufrad gesehen nach hinten wandert, wird gleichzeitig das vordere Reibrad 15v abgehoben und dessen Oberfläche kommt in Kontakt mit der Innenfläche der Zusatzschiene 14. Da durch das Federelement 23 die Reibräder 15 zueinander beaufschlagt sind, wird diese Kraft durch Abstützung der Reibräder 15 an der Zusatzschiene 14 an das Laufrad 3 weitergegeben.At the same time, in the rest position, the rear friction wheel is 15h relative to the tread of the Rail 5 seen at a level arranged so that the surface of the rear Friction wheels 15h when retracting the undercarriage 1 into a section of the rail 5 an additional rail 14 with a beveled or as an inlet funnel trained initial section comes into contact and then down and is pressed between the inner surface of the additional rail 14 and the rail 5. Through this process of pushing the rear friction wheel down 15h, whereby at the same time this friction wheel 15h seen relative to the impeller to the rear moves, the front friction wheel 15v is lifted off simultaneously and its surface comes into contact with the inner surface of the additional rail 14 Spring element 23, the friction wheels 15 are applied to each other, this force by supporting the friction wheels 15 on the additional rail 14 on the impeller 3 passed.

Für den Fall, daß sich der Abstand zwischen der Lauffläche auf dem Oberflansch 4 der Schiene 5 und der Innenseite der Zusatzschiene 14 ändert, würden die Reibräder 15, beaufschlagt durch das Federelement 23, sich sofort aufeinander zu oder voneinander weg bewegen und somit unter Beibehaltung der Andruckkraft auf das Laufrad 3 und die Zusatzschiene 14 die Abstandsänderung zwischen der Schiene 5 und der Zusatzschiene 14 ausgleichen.In the event that the distance between the tread on the upper flange 4 of Rail 5 and the inside of the additional rail 14 changes, the friction wheels 15, acted upon by the spring element 23, immediately towards each other or from each other move away and thus while maintaining the pressure on the impeller 3 and the additional rail 14 the change in distance between the rail 5 and the Compensate additional rail 14.

Desweiteren ist aus der Figur 3 eine Draufsicht auf Figur 2 zu entnehmen. In dieser Draufsicht ist aus Gründen der Übersichtlichkeit die Zusatzschiene 14 nicht dargestellt. Dieser Figur 3 ist der grundsätzliche Aufbau des Verbindungselementes 16 zu entnehmen. Es ist ersichtlich, daß das Schwingenteil 17 und das Winkelteil 18 jeweils in doppelter Ausfertigung vorhanden ist und zwischen den beiden jeweiligen Teilen des Schwingenteils 17 und des Winkelteils 18 die Reibräder 15 über Achsen gelagert sind. Somit ist eine exakte Führung der den Reibschluß verstärkenden Reibräder 15 gewährleistet. Desweiteren ist der Aufbau des Federelementes 23 aus zwei Federn ersichtlich. Auch ist im Bereich des vorderen Endes des Schwingenteils 17 die Anordnung der Gewichtselemente 28 im Bereich des Bolzenelementes 25 ersichtlich. Die Gewichtselemente 28 sind an den Innenseiten der jeweiligen Schwingenteil 17 angeordnet sowie zylinderförmig ausgebildet. An den den Schwingenteilen 17 gegenüberliegenden Enden der Gewichtselemente 28 schließt sich jeweils unter Beibehaltung eines geringen Spaltes das Tragelement 27 mit der Öffnung 26 an. Durch die flächige Anlage der Enden der Gewichtselemente 28 an dem Tragelement 27 ist zusätzlich eine seitliche Führung der Reibräder 15 auf dem Laufrad 3 gewährleistet. Furthermore, a top view of FIG. 2 can be seen from FIG. In this Top view, the additional rail 14 is not shown for reasons of clarity. This figure 3 is the basic structure of the connecting element 16 remove. It can be seen that the rocker member 17 and the angle member 18 each exists in duplicate and between the two respective parts of the Swinging part 17 and the angle part 18, the friction wheels 15 are mounted on axes. This is an exact guidance of the friction wheels 15 which reinforce the frictional engagement guaranteed. Furthermore, the construction of the spring element 23 from two springs seen. Also in the region of the front end of the rocker part 17 Arrangement of the weight elements 28 in the region of the bolt element 25 can be seen. The weight elements 28 are on the inner sides of the respective rocker part 17 arranged as well as cylindrical. On the swing arm parts 17th opposite ends of the weight elements 28 each closes below Maintaining a small gap, the support member 27 with the opening 26 on. Due to the flat contact of the ends of the weight elements 28 on the support element 27 is additionally a lateral guidance of the friction wheels 15 on the impeller 3 guaranteed.
