Elektrohängebahnen sind beispielsweise in der DE 42 05 858 A1 und der EP 0 577 917 A1 beschrieben.Electric monorail systems are for example in the DE 42 05 858 A1 and the EP 0 577 917 A1 described.

Neben diesen gibt es vom Markt her bekannte derartige Elektrohängebahnen, bei denen die Antriebsrolle zugleich als Tragrolle dient und auf der Oberseite der Tragschiene abrollt. Bei anderen bekannten Elektrohängebahnen rollt die Antriebsrolle auf der Unterseite der Tragschiene oder auf einer seitlichen vertikalen Lauffläche derselben ab. Bei all diesen Varianten ist es für einen zuverlässigen Betrieb der Elektrohängebahn wichtig, dass die Reibungskräfte zwischen der Antriebsrolle und der Tragschiene stets ausreichend groß sind, damit der Tragwagen ohne ein Durchrutschen der Antriebsrolle auf der Tragschiene verfährt. In letzterem Fall können die gewünschten Antriebs- bzw. Verzögerungskräfte zwischen dem Tragwagen und der Tragschiene nicht mehr ausreichend sicher übertragen werden.In addition to these there are known from the market such overhead monorail systems in which the drive roller also serves as a supporting role and rolls on top of the mounting rail. In other known electric monorail rolls Drive roller on the underside of the mounting rail or on a lateral vertical tread of the same from. In all these variants, it is important for reliable operation of the monorail system that the frictional forces between the drive roller and the mounting rail are always sufficiently large, so that the carriage moves without slippage of the drive roller on the mounting rail. In the latter case, the desired drive or deceleration forces between the wagon and the mounting rail can no longer be transmitted with sufficient security.

Insbesondere bei Elektrohängebahnen, bei denen die Antriebsrolle zugleich als Tragrolle dient und auf einer oberen Lauffläche der Tragschiene abrollt, kann es zu Schwierigkeiten in geneigten Abschnitten der Tragschiene kommen. Solche liegen bei Elektrohängebahnen vor, mit denen auch Höhenunterschiede überwunden werden sollen. Wenn sich der Tragwagen mit dem zu transportierenden Gegenstand in einem geneigten Abschnitt befindet, wirkt nicht mehr das volle Gewicht der Last auf den Tragwagen, sondern es wirkt nur noch die senkrecht auf der Tragschiene stehenden Komponente des Gewichts als Normalkraft, welche für die Reibungskräfte verantwortlich ist. Zudem ist in einem geneigten Abschnitt der Tragschiene die von der Antriebsrolle auf die Tragschiene zu übertragende Kraft größer, da nicht nur die beim Verfahren des Tragwagens entstehenden Reibungskräfte zu überwinden sind, sondern auch eine Kraft in vertikaler Richtung aufgebracht werden muss, um eine Steigung zu bewältigen bzw. den Tragwagen gegen eine Hangabtriebskraft zu halten.In particular, in overhead monorail systems in which the drive roller at the same time serves as a support roller and rolls on an upper running surface of the mounting rail, there may be difficulties in inclined portions of the support rail. Such are available in monorail systems, with which height differences are to be overcome. When the wagon with the object to be transported is in an inclined section, the full weight of the load no longer acts on the wagon, but only the component of the weight perpendicular to the mounting rail acts as a normal force, which is responsible for the frictional forces , In addition, in an inclined portion of the support rail, the force to be transmitted from the drive roller to the mounting rail is greater, since not only the frictional forces arising during the process of the trolley are to overcome, but also a force must be applied in the vertical direction to cope with a slope or to hold the wagon against a downgrade force.

Wenn der geneigte Abschnitt der Tragschiene eine bestimmte Steigung oder ein bestimmtes Gefälle hat, oder anders ausgedrückt, wenn der geneigte Abschnitt einen bestimmten Neigungswinkel-Schwellenwert überschreitet, kann es dann zu einem Durchrutschen der Antriebsrolle auf der Tragschiene kommen.If the inclined portion of the support rail has a certain slope or a certain slope, or in other words, if the inclined portion exceeds a certain inclination angle threshold, then it can lead to slippage of the drive roller on the support rail.

Um dem entgegenzuwirken, ist die Anpresseinrichtung bei den bekannten Elektrohängebahn der eingangs genannten Art so eingerichtet, dass der Abstand zwischen der Drehachse der Antriebsrolle und der Tragschiene verringert wird, sobald der Tragwagen in einen geneigten Abschnitt der Tragschiene einfährt. Durch die Verringerung des Abstandes zwischen der Drehachse der Antriebsrolle und der Tragschiene wird der Anpressdruck der Antriebsrolle gegen die Tragschiene erhöht. Auch bei geringen Neigungswinkeln der Tragschiene, welche unterhalb eines Neigungswinkel-Schwellenwerts liegen und bei denen es noch nicht zu einem Durchrutschen der Antriebsrolle kommt, wird somit deren Anpressdruck erhöht. Dies bedeutet, dass zum Verfahren des Tragwagens größere Reibungskräfte überwunden werden müssen als ohne erhöhten Anpressdruck der Antriebsrolle. Dies wiederum ist mit einer Erhöhung des Energiebedarfs für die Bewegung des Tragwagens verbunden.To counteract this, the pressing device in the known electric monorail of the type mentioned is set up so that the distance between the axis of rotation of the drive roller and the support rail is reduced as soon as the trolley moves into an inclined portion of the support rail. By reducing the distance between the axis of rotation of the drive roller and the support rail of the contact pressure of the drive roller is increased against the support rail. Even at low angles of inclination of the support rail, which lie below an angle of inclination threshold and in which there is no slippage of the drive roller, thus the contact pressure is increased. This means that greater friction forces must be overcome for moving the carrier cart as without increased contact pressure of the drive roller. This in turn is associated with an increase in the energy requirements for the movement of the trolley.

Abhängig von den örtlichen Gegebenheiten gibt es jedoch Elektrohängebahnen mit unterschiedlich geneigten Abschnitten der Tragschiene, welche auch geneigte Abschnitte mit einer Neigung unterhalb eines Neigungswinkel-Schwellenwertes umfassen, bei welcher auf eine Erhöhung des Anpressdrucks der Antriebsrolle gegen die Tragschiene verzichtet werden könnte, ohne dass es zu einem Durchrutschen der Antriebsrolle gegenüber der Tragschiene käme.Depending on the local conditions, however, there are overhead monorail systems with differently inclined sections of the mounting rail, which also include inclined sections with a slope below a tilt angle threshold, in which an increase in the contact pressure of the drive roller against the mounting rail could be dispensed without it slipping of the drive roller relative to the support rail would come.

Der jeweilige Neigungswinkel-Schwellenwert hängt unter anderem von der Bauart der Elektrohängebahn und den zu transportierenden Gegenständen bzw. von deren Gewicht ab.The respective angle of inclination threshold depends, inter alia, on the type of electric monorail and the objects to be transported or on their weight.

Im Hinblick auf den Energieverbrauch einer Elektrohängebahn der eingangs genannten Art ist es also wünschenswert, dass der Anpressdruck der Antriebsrolle gegen die Tragschiene nicht erhöht wird, wenn der Tragwagen in einen geneigten Abschnitt der Tragschiene einfährt, dessen Neigung keine Erhöhung des Anpressdruckes der Antriebsrolle gegen die Tragschiene erfordert. Daher wird also dafür gesorgt, dass der Anpressdruck der Antriebsrolle gegen die Lauffläche der Tragschiene nur dann erhöht wird, wenn der Neigungswinkel des geneigten Abschnitts der Tragschiene so groß wird, dass es ohne weitere Maßnahmen zu einem Durchrutschen der Antriebsrolle käme.In view of the energy consumption of a monorail system of the type mentioned, it is therefore desirable that the contact pressure of the drive roller against the mounting rail is not increased when the carriage moves into an inclined portion of the support rail, the inclination does not require increasing the contact pressure of the drive roller against the support rail. Therefore, therefore, it is ensured that the contact pressure of the drive roller against the running surface of the support rail is only increased if the inclination angle of the inclined portion of the support rail is so large that it would come without further measures to a slippage of the drive roller.

Es ist Aufgabe der vorliegenden Erfindung, eine Elektrohängebahn der eingangs genannten Art zu schaffen, welche den obigen Gedanken Rechnung trägt und bei der eine vorteilhafte Ausbildung der Anpresseinrichtung verwirklicht ist. Diese Aufgabe wird bei einer Elektrohängebahn der eingangs genannten Art dadurch gelöst, dass

  • e) die Anpresseinrichtung ein Wippenelement umfasst, welches an dem Fahrwerk zwischen einem ersten freien Wippenabschnitt und einem zweiten freien Wippenabschnitt um eine horizontale Wippenachse verschwenkbar gelagert ist und an dem ersten freien Wippenabschnitt mit der Antriebsrolle oder einer Gegendruckrolle gekoppelt ist, die auf einer Gegenlauffläche der Tragschiene abrollt, und an dem zweiten freien Wippenabschnitt mit dem zu transportierenden Gegenstand verbindbar ist.
It is an object of the present invention to provide an electric monorail of the type mentioned above, which takes into account the above idea and in which an advantageous embodiment of the pressing device is realized. This object is achieved in an electric monorail of the type mentioned fact that
  • e) the pressing device comprises a rocker element which is pivotally mounted on the chassis between a first free rocker section and a second free rocker section about a horizontal rocker axis and is coupled to the first free rocker section with the drive roller or a counter-pressure roller on a mating surface of the mounting rail unrolls, and is connectable to the second free rocker section with the object to be transported.

Die Gegenlauffläche der Gegendruckrolle ist vorzugsweise gegenüber der Lauffläche der Antriebsrolle an der Tragschiene ausgebildet. Wenn das Gewicht des Gegenstandes den zweiten freien Wippenabschnitt nach unten bewegt, bewegt sich das freie Ende des ersten freien Wippenabschnitts nach oben. Diese Bewegung kann so auf die Lagerung der Antriebsrolle oder der Gegendruckrolle übertragen werden, dass diese in Richtung auf die Tragschiene bewegt wird, wodurch der Anpressdruck der Antriebsrolle gegen die Tragschiene erhöht wird.The mating surface of the counter-pressure roller is preferably formed opposite the running surface of the drive roller on the support rail. As the weight of the article moves down the second free rocker section, the free end of the first free rocker section moves upward. This movement can be transferred to the storage of the drive roller or the counter-pressure roller, that in Direction is moved to the support rail, whereby the contact pressure of the drive roller is increased against the support rail.

Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen angegeben.Advantageous developments are specified in the dependent claims.

Insbesondere ist es günstig, wenn das Fahrwerk des Tragwagens eine Gegendruckrolle umfasst und die Antriebsrolle auf einer oberen oder einer unteren Lauffläche der Tragschiene und die Gegendruckrolle auf einer gegenüberliegenden unteren oder oberen Lauffläche abrollt, wobei der erste freie Wippenabschnitt des Wippengliedes die auf der unteren Lauffläche der Tragschiene abrollende Rolle lagert. Wenn das Gewicht des Gegenstandes den zweiten freien Wippenabschnitt nach unten zieht, wird die am ersten freien Wippenabschnitt gelagerte Rolle in Richtung auf die Tragschiene bewegt. Dadurch verringert sich der Abstand zwischen den beiden Achsen der Antriebsrolle und der Gegendruckrolle, wodurch sich auch der Abstand der Drehachse der Antriebsrolle zur oberen Lauffläche der Tragschiene verringert und der Anpressdruck der Antriebsrolle gegen die Tragschiene erhöht wird.In particular, it is advantageous if the chassis of the trolley comprises a counter-pressure roller and the drive roller rolls on an upper or a lower running surface of the support rail and the counter-pressure roller on an opposite lower or upper tread, wherein the first free rocker portion of the rocker member on the lower running surface of the Support rail rolling roller stores. As the weight of the article pulls down the second free rocker section, the roller mounted on the first free rocker section is moved toward the support rail. This reduces the distance between the two axes of the drive roller and the counter-pressure roller, which also reduces the distance between the axis of rotation of the drive roller to the upper running surface of the support rail and the contact pressure of the drive roller is increased against the support rail.

In diesem Fall müssen die Mittel, durch welche eine Verringerung des Abstands zwischen der Drehachse der Antriebsrolle und der Tragschiene unterbunden werden kann, das Wippenelement abhängig vom Neigungswinkel des geneigten Abschnitts der Tragschiene freigeben oder fixieren.In this case, the means by which a reduction in the distance between the rotational axis of the drive roller and the support rail can be prevented, the rocker element depending on the inclination angle of the inclined portion of the support rail release or fix.

Dies kann in vorteilhafter Weise erreicht werden, indem

  1. a) an den zweiten freien Wippenabschnitt ein Koppelglied angelenkt ist, welches mit dem zu transportierenden Gegenstand verbindbar ist und gegenüber einer Vertikalen um eine Schwenkachse verschwenken kann;
  2. b) die Anpresseinrichtung ein Tragelement mit einer Auflagefläche umfasst, welches an dem Fahrwerk befestigt ist;
  3. c) das Koppelglied mit einem Auflageabschnitt auf der Auflagefläche aufliegt und an einer Bewegung nach unten gehindert ist, wenn der Tragwagen sich in einem geneigten Abschnitt der Tragschiene befindet, dessen Neigungswinkel kleiner als der Neigungswinkel-Schwellenwert ist;
  4. d) die Auflagefläche in wenigstens eine Richtung der Verschwenkung des Koppelgliedes eine solche Erstreckung aufweist, dass die Auflagefläche des Tragelements das Koppelglied freigibt, wenn der Tragwagen sich in einem geneigten Abschnitt der Tragschiene befindet, dessen Neigungswinkel größer als oder gleich groß wie der Neigungswinkel-Schwellenwert ist.
This can be achieved in an advantageous manner by
  1. a) to the second free rocker section, a coupling member is articulated, which is connectable to the object to be transported and can pivot relative to a vertical about a pivot axis;
  2. b) the pressing device comprises a support member having a support surface which is fixed to the chassis;
  3. c) the coupling member rests with a support portion on the support surface and is prevented from moving downward when the wagon is in an inclined portion of the support rail whose inclination angle is smaller than the inclination angle threshold;
  4. d) the bearing surface in at least one direction of the pivoting of the coupling member has such an extent that the support surface of the support member releases the coupling member when the cart is in an inclined portion of the support rail whose inclination angle greater than or equal to the inclination angle threshold is.

Bei dieser Ausbildung der Anpresseinrichtung wird das Gewicht des zu transportierenden Gegenstandes so lange über die Auflagefläche von dem Fahrwerk bzw. dessen auf der oberen Lauffläche abrollenden Rolle getragen, ohne dass es zu einer Erhöhung des Anpressdruckes der Antriebsrolle oder der Gegendruckrolle gegen die Tragschiene kommt, wie der Neigungswinkel des geneigten Abschnitts unterhalb des Neigungswinkel-Schwellenwertes liegt. Sobald der Neigungswinkel-Schwellenwert überschritten wird, rutscht das Koppelglied gleichsam von der Auflagefläche des Tragelements herunter und wird von dieser freigegeben. Dadurch kann das Wippenelement durch die darauf übertragene Last verschwenken und die Gegendruckrolle gegen die untere Lauffläche anpressen, was auf Grund des wirkenden Hebels zu einer Erhöhung des Anpressdruckes der Antriebsrolle gegen die Tragschiene führt.In this embodiment of the pressing device, the weight of the object to be transported is carried so long over the support surface of the chassis or its rolling on the upper tread roller, without causing an increase in the contact pressure of the drive roller or the counter-pressure roller against the mounting rail, such as the inclination angle of the inclined portion is below the inclination angle threshold value. As soon as the angle of inclination threshold is exceeded, the coupling member, as it were, slides down from the support surface of the support element and is released by it. As a result, the rocker element can pivot through the load transmitted thereon and press the counter-pressure roller against the lower running surface, resulting in an increase of the contact pressure of the drive roller against the mounting rail due to the acting lever.

Ein guter Kontakt des Koppelgliedes mit der die Last aufnehmenden Auflagenfläche in einem geneigten Abschnitt der Tragschiene, dessen Neigung unterhalb des Neigungswinkel-Schwellenwertes ist, ist gewährleistet, wenn der Auflageabschnitt des Koppelgliedes ein Rundbolzen, welcher sich in horizontaler Richtung senkrecht zur Tragschiene erstreckt, oder eine Auflagerolle ist, welche um eine Drehachse verdrehbar gelagert ist, die sich in horizontaler Richtung senkrecht zur Tragschiene erstreckt.Good contact of the coupling member with the load-bearing support surface in an inclined portion of the support rail, the inclination below the inclination angle threshold is, is ensured if the support portion of the coupling member is a round bolt which extends in the horizontal direction perpendicular to the support rail, or a Auflagerolle which is rotatably mounted about a rotation axis which extends in the horizontal direction perpendicular to the support rail.

Die Auflagefläche kann an die Schwenkbewegung des Koppelgliedes bzw. des Auflagebolzens oder der Auflagerolle angepasst sein, wenn sie nach außen gekrümmt ist.The support surface may be adapted to the pivotal movement of the coupling member or the support pin or the Auflagerolle when it is curved outward.

Um die Laufstabilität des Tragwagens gegenüber der Tragschiene zu erhöhen, kann der Tragwagen, wenn bereits die oben angegeben Gegendruckrolle vorhanden ist, eine weitere Gegendruckrolle umfassen, die auf der Gegenlauffläche der Tragschiene abrollt und an dem Fahrwerk des Tragwagens gelagert ist.In order to increase the running stability of the trolley relative to the mounting rail, the trolley, if already the above-mentioned counter-pressure roller is present, comprise a further counter-pressure roller which rolls on the mating surface of the support rail and is mounted on the chassis of the trolley.

In der Praxis hat es sich als vorteilhaft erwiesen, wenn der Neigungswinkel-Schwellenwert etwa 5° bis 15°, vorzugsweise 10° beträgt. Insbesondere bis zu einer Steigung von 10° erfolgt üblicherweise kein Durchrutschen des Antriebsrades auf der Tragschiene, so dass der Tragwagen bei Steigungen oder Gefällen bis zu 10° ohne Erhöhung des Anpressdruckes der Antriebsrolle gegenüber der Tragschiene betrieben werden kann.In practice, it has proved to be advantageous if the inclination angle threshold is about 5 ° to 15 °, preferably 10 °. In particular, up to a pitch of 10 ° is usually no slippage of the drive wheel on the mounting rail, so that the car can be operated on slopes or gradients up to 10 ° without increasing the contact pressure of the drive roller relative to the mounting rail.

Zunächst wird auf Figur 1 Bezug genommen. In dieser ist ein Ausschnitt einer Elektrohängebahn 2 gezeigt, welche eine Tragschiene 4, von der in Figur 1 ein horizontaler Abschnitt 6 gezeigt ist, und einen auf der Tragschiene 4 verfahrbaren Tragwagen 8 umfasst.First, it will open FIG. 1 Referenced. In this a section of a monorail system 2 is shown, which a support rail 4, from the in FIG. 1 a horizontal section 6 is shown, and a movable on the support rail 4 carriage 8 includes.

Die Tragschiene 4 ist in herkömmlicher Weise als I-Profil ausgeführt und bedarf daher keiner näheren Erläuterung. Sie ist in an und für sich bekannter Weise an einer Deckenkonstruktion oder einem Stahlbau aufgehängt und verläuft über dem Niveau des Raumbodens.The support rail 4 is designed in a conventional manner as I-profile and therefore requires no further explanation. It is suspended in a manner known per se on a ceiling construction or a steel structure and extends above the level of the room floor.

Wie in den Figuren 2 und 3 zu erkennen ist, verlaufen entlang der Tragschiene 4 auf deren vertikaler Seitenfläche 10, die der in Figur 1 zu erkennenden Seitenfläche 12 der Tragschiene 4 gegenüberliegt, verschiedene Schleifleitungen 14. Diese dienen der Stromversorgung des Tragwagens 8 sowie der Signalübermittlung zu diesem. Auch die Schleifleitungen 14 entsprechen dem Stand der Technik.As in the Figures 2 and 3 can be seen running along the support rail 4 on the vertical side surface 10, the in FIG. 1 facing side surface 12 of the support rail 4 is opposite, different contact rails 14. These serve the power supply of the trolley 8 and the signal transmission to this. Also, the contact lines 14 correspond to the prior art.

Der Tragwagen 8 umfasst ein die Tragschiene 4 umgreifendes Fahrwerk 16, welches eine auf der oberen Lauffläche 18 der Tragschiene 4 abrollende Antriebsrolle 20 lagert. Die Antriebsrolle 20 ist um eine horizontale Drehachse 21 verdrehbar, welche senkrecht zur Tragschiene 4 verläuft. Die Antriebsrolle 20 dient beim vorliegenden Ausführungsbeispiel zugleich als Tragrolle. Die Antriebsrolle 20 wird mittels eines Elektromotors 22 angetrieben, welcher über die Schleifleitungen 14 bestromt und angesteuert wird.The wagon 8 comprises a support rail 4 encompassing chassis 16, which supports a rolling on the upper tread 18 of the support rail 4 drive roller 20. The drive roller 20 is rotatable about a horizontal axis of rotation 21, which runs perpendicular to the support rail 4. The drive roller 20 serves in the present embodiment at the same time as a supporting role. The drive roller 20 is driven by means of an electric motor 22 which is energized and driven via the contact rails 14.

Das Fahrwerk 16 lagert zudem in an und für sich bekannter Weise seitliche Führungsrollen 24, welche sich um senkrecht zur oberen Lauffläche 18 der Tragschiene 4 verlaufende Achsen drehen können und von denen jeweils zwei seitlich an sich gegenüberliegenden oberen vertikalen Führungslaufflächen 26 und sich gegenüberliegenden unteren vertikalen Führungslaufflächen 28 der Tragschiene 4 abrollen.The chassis 16 also supports in known manner lateral guide rollers 24 which can rotate about perpendicular to the upper tread 18 of the support rail 4 extending axes and of which two laterally opposite to each other at the upper vertical guide treads 26 and opposite lower vertical guide treads 28 of the support rail 4 unroll.

Das Fahrwerk 16 des Tragwagens 8 besitzt außerdem eine erste Gegendruckrolle 30, welche in der durch einen Pfeil 32 angedeuteten Transportrichtung des Tragwagens 8 der Antriebsrolle 20 nacheilend auf der unteren Lauffläche 34 der Tragschiene 4 abrollt. Ferner umfasst das Fahrwerk 16 eine zweite Gegendruckrolle 36, welche in Transportrichtung 32 der Antriebsrolle 20 vorauseilend auf der unteren Lauffläche 34 der Tragschiene 4 abrollt. Die nacheilende Gegendruckrolle 30 ist mittels einer Anpresseinrichtung 38 gelagert, durch welche der Anpressdruck der Antriebsrolle 20 gegen die obere Lauffläche 18 der Tragschiene 4 erhöht werden kann, indem der Abstand zwischen der Drehachse 40 der Gegendruckrolle 30 und der unteren Lauffläche 34 der Tragschiene 4 verändert wird.The chassis 16 of the trolley 8 also has a first counter-pressure roller 30, which unwinds in the direction indicated by an arrow 32 transport direction of the support carriage 8 of the drive roller 20 on the lower running surface 34 of the support rail 4. Furthermore, the chassis 16 includes a second counter-pressure roller 36, which rolls in advance in the transport direction 32 of the drive roller 20 on the lower running surface 34 of the support rail 4. The trailing counter-pressure roller 30 is mounted by means of a pressing device 38, by which the contact pressure of the drive roller 20 against the upper running surface 18 of the support rail 4 can be increased by the distance between the axis of rotation 40 of the counter-pressure roller 30 and the lower running surface 34 of the support rail 4 is changed ,

Dazu umfasst die Anpresseinrichtung 38 ein an der Unterseite des Fahrwerks 16 des Tragwagens 8 um eine horizontal und senkrecht zur Transportrichtung 32 verlaufende Wippenachse 42 verschwenkbar gelagertes Wippenglied 44. Die Wippenachse 42 verläuft damit parallel zur Drehachse 40 der nacheilenden Gegendruckrolle 30. Diese wiederum ist am freien Ende eines in zur Transportrichtung 32 entgegengesetzte Richtung weisenden ersten freien und geradlinigen Wippenabschnitts 46 gelagert, welcher horizontal verläuft, wenn sich der Tragwagen 8 in einem horizontalen Abschnitt der Tragschiene 4 befindet. Der dem ersten Wippenabschnitt 46 gegenüberliegende zweite Wippenabschnitt 48 ist als 90°-Winkel ausgebildet, dessen freier Schenkel parallel zum ersten Wippenabschnitt 46 verläuft, jedoch diesem gegenüber nach unten versetzt ist.For this purpose, the pressing device 38 comprises a on the underside of the chassis 16 of the cart 8 to a horizontal and The rocker axis 42 extends parallel to the axis of rotation 40 of the trailing counter-pressure roller 30. This in turn is at the free end of an in the opposite direction to the transport direction 32 facing first free and rectilinear rocker section 46 is mounted, which is horizontal runs when the wagon 8 is located in a horizontal portion of the support rail 4. The first rocker section 46 opposite second rocker section 48 is formed as a 90 ° angle, the free leg is parallel to the first rocker section 46, but this is offset towards the bottom.

An das freie Ende des zweiten Wippenabschnitts 48, welches in Transportrichtung 32 weist, ist ein längliches Koppelglied 50 über eine horizontale Schwenkachse 52 angelenkt, die sich senkrecht zur Transportrichtung 32 erstreckt. Somit kann das Koppelglied 50 gegenüber dem Wippenglied 44 und einer vertikalen Ebene, die senkrecht zur Tragschiene 4 steht, verschwenken. Durch die Ausbildung des zweiten freien Wippenabschnitts 48 als 90°-Winkel ist die Schwenkachse 52 des Koppelgliedes 50 gegenüber der Wippenachse 42 nach unten versetzt angeordnet, wenn sich der Transportwagen 8 in einem horizontalen Abschnitt der Tragschiene 4 befindet (vgl. Figur 1).At the free end of the second rocker section 48, which has in the transport direction 32, an elongated coupling member 50 is articulated via a horizontal pivot axis 52 which extends perpendicular to the transport direction 32. Thus, the coupling member 50 with respect to the rocker member 44 and a vertical plane which is perpendicular to the support rail 4, pivot. Due to the design of the second free rocker section 48 as a 90 ° angle, the pivot axis 52 of the coupling member 50 is offset relative to the rocker axis 42 down when the trolley 8 is in a horizontal portion of the support rail 4 (see Figure 1).

Die Längsachsen der Schwenkachse 52 des Koppelgliedes 50 und der Wippenachse 42 liegen in einer gemeinsamen, im wesentlichen horizontalen Ebene, wenn sich der Tragwagen 8 in einem horizontalen Abschnitt der Tragschiene 4 befindet, wie es in Figur 1 gezeigt ist.The longitudinal axes of the pivot axis 52 of the coupling member 50 and the rocker axis 42 lie in a common, substantially horizontal plane when the carriage 8 is in a horizontal portion of the support rail 4, as in FIG. 1 is shown.

Das Koppelglied 50 weist einen der Tragschiene 4 benachbarten Auflageabschnitt 54 auf, welcher in Richtung von der Tragschiene 4 weg in einen Tragabschnitt 56 übergeht. Am Übergang des Auflageabschnitts 54 zum Tragabschnitt 56 ist das Koppelglied 50 über die Schwenkachse 52 gelagert. Am nach unten weisenden freien Ende des Tragabschnitts 56 ist beim hier gezeigten Ausführungsbeispiel ein horizontaler und senkrecht zur Transportrichtung 32 verlaufender Tragbolzen 58 angeordnet, über den ein in den Figuren 1, 4 und 5 schematisch angedeutetes und an und für sich bekanntes Transportgehänge 60, das mit zu transportierenden Gegenständen beladen werden kann, an den Tragwagen 8 angehängt ist.The coupling member 50 has a support rail 4 adjacent support portion 54 which in the direction of the Support rail 4 away in a support section 56 passes. At the transition of the support portion 54 to the support portion 56, the coupling member 50 is mounted on the pivot axis 52. At the downwardly facing free end of the support portion 56 a horizontal and perpendicular to the transport direction 32 supporting bolt 58 is arranged in the embodiment shown here, via the one in the FIGS. 1 . 4 and 5 schematically indicated and in itself known transport hanger 60, which can be loaded with objects to be transported, is attached to the wagon 8.

Am freien Ende des Auflageabschnitts 54 trägt das Koppelglied 50 einen horizontalen Auflagebolzen 62, welcher sich senkrecht zur Transportrichtung 32 erstreckt. Die Längsachsen der Schwenkachse 52, des Tragbolzens 58 und des Auflagebolzens 62 des Koppelgliedes 50 liegen in einer gemeinsamen Ebene. Bei einer nicht eigens gezeigten Abwandlung ist anstelle des Auflagebolzens 62 eine Auflagerolle vorgesehen, welche um eine Drehachse verdrehbar an dem Koppelglied 50 gelagert ist, die sich in horizontaler Richtung senkrecht zur Tragschiene 4 erstreckt.At the free end of the support portion 54, the coupling member 50 carries a horizontal support pin 62, which extends perpendicular to the transport direction 32. The longitudinal axes of the pivot axis 52, the support pin 58 and the support pin 62 of the coupling member 50 lie in a common plane. In a modification not specifically shown, a support roller is provided instead of the support pin 62, which is mounted rotatably about a rotation axis on the coupling member 50 which extends in the horizontal direction perpendicular to the support rail 4.

Mit dem Auflagebolzen 62 liegt das Koppelglied 50 auf einer Auflagefläche 64 eines starr an der Unterseite des Fahrwerks 16 des Tragwagens 8 befestigten Tragstutzens 66 auf. Die Auflagefläche 64 verläuft in einer horizontalen Ebene, wenn sich der Tragwagen 8 innerhalb eines horizontalen Abschnitts der Tragschiene 4 befindet, wie es in Figur 1 gezeigt ist. Die Auflagenfläche 64 kann in einer Abwandlung auch in Richtung auf die Tragschiene 4 nach außen gekrümmt sein.With the support pin 62, the coupling member 50 rests on a bearing surface 64 of a rigidly secured to the underside of the chassis 16 of the carrier carriage 8 support stub 66. The support surface 64 extends in a horizontal plane when the carriage 8 is within a horizontal portion of the support rail 4, as shown in FIG FIG. 1 is shown. The support surface 64 may be curved in a modification in the direction of the support rail 4 to the outside.

Wenn das Koppelglied 50 nach unten bewegt wird, verringert sich der Abstand zwischen der Drehachse 40 der nacheilenden Gegendruckrolle 30 und der Tragschiene 4. In diesem Fall verschwenkt das Wippenglied 44 um seine Wippenachse 42 und drückt die nacheilende Gegendruckrolle 30 gegen die untere Lauffläche 34 der Tragschiene 4 an.When the coupling member 50 is moved downward, the distance between the rotation axis 40 of the trailing counter pressure roller 30 and the support rail 4 decreases. In this case, the rocker member 44 pivots about its rocker axis 42 and presses the trailing counter-pressure roller 30 against the lower running surface 34 of the support rail 4.

Wenn das Koppelglied 50 mit seinem Auflagebolzen 62 auf der Auflagefläche 64 des Tragstutzens 66 aufliegt, ist die nacheilende Gegendruckrolle 30 an einer Bewegung in Richtung auf die Tragschiene 4 gehindert und drückt mit einem Anpressdruck gegen deren untere Lauffläche 34 an, welcher in etwa dem Anpressdruck der vorauseilenden Gegendruckrolle 36 gegen die Tragschiene 4 entspricht und durch die Bauart des Tragwagens vorgegeben ist. Das Gewicht des Transportgehänges 60 wird in diesem Fall vollständig über den Tragstutzen 66 und das Fahrwerk 16 von der Antriebsrolle 20 des Tragwagens 8 aufgenommen. Die Antriebsrolle 20 drückt dadurch mit einem Anpressdruck gegen die obere Lauffläche 18 der Tragschiene 4, welche abhängig von der Gewichtskraft des Transportgehänges 60 ist.When the coupling member 50 rests with its support pin 62 on the support surface 64 of the support stub 66, the trailing counter-pressure roller 30 is prevented from moving in the direction of the support rail 4 and presses with a contact pressure against the lower tread 34, which is approximately the contact pressure of Anticipating counter-pressure roller 36 corresponds to the mounting rail 4 and is predetermined by the design of the trolley. The weight of the transport hanger 60 is taken in this case completely on the support sleeve 66 and the chassis 16 of the drive roller 20 of the cart 8. The drive roller 20 thereby presses with a contact pressure against the upper running surface 18 of the support rail 4, which is dependent on the weight of the Transportgehänges 60.

Wenn der Tragwagen 8 aus einem horizontalen Abschnitt der Tragschiene 4 in einen gegenüber einer horizontalen Ebene nach oben geneigten Abschnitt 68 einfährt, wie er in einem Ausschnitt in Figur 4 gezeigt ist, verschwenkt das Koppelglied 50 um seine Schwenkachse 52 so, dass diese und der Tragbolzen 58 stets in einer im wesentlichen vertikalen Ebene verlaufen. Dabei bewegt sich der Auflagebolzen 62 entlang der Auflagefläche 64 des Tragstutzens 66. Anders ausgedrückt verkippt die Auflagefläche 64 gegenüber dem Auflagebolzen 62 am Koppelglied 50.When the cart 8 moves from a horizontal portion of the support rail 4 in a relation to a horizontal plane upwardly inclined portion 68, as shown in a cutout in FIG. 4 is shown, the coupling member 50 pivots about its pivot axis 52 so that these and the support pin 58 always extend in a substantially vertical plane. In this case, the support pin 62 moves along the support surface 64 of the support stub 66. In other words, the support surface 64 tilts relative to the support pin 62 on the coupling member 50th

Bis zu einem bestimmten Neigungswinkel des nach oben geneigten Abschnitts 68 der Tragschiene 4 gegenüber einer horizontalen Ebene bleibt der Auflagebolzen 62 des Koppelgliedes 50 stets in Kontakt mit der Auflagefläche 64 des Tragstutzens 66, so dass das Gewicht des Transportgehänges 60 mit zu transportierenden Gegenständen von dem Fahrwerk 16 des Tragwagens 8 bzw. von dessen Antriebsrolle 20 aufgenommen wird.Up to a certain angle of inclination of the upwardly inclined portion 68 of the support rail 4 with respect to a horizontal plane of the support pin 62 of the coupling member 50 is always in contact with the support surface 64 of the support stub 66, so that the weight of the Transportgehänges 60 with objects to be transported by the chassis 16 of the trolley 8 or is absorbed by the drive roller 20.

Wenn der Neigungswinkel des geneigten Abschnitts 68 der Tragschiene 4 einen Wert einnimmt, bei welchem das Koppelglied 50 so weit um seine Schwenkachse 52 gegenüber der Auflagefläche 64 verschwenkt, dass sein Auflagebolzen 62 nicht mehr auf der Auflagefläche 64 aufliegt und sich in Transportrichtung 32 über deren Rand hinaus bewegt, wie es in Figur 4 zu sehen ist, kann das nun freigegebene Wippenglied 44 um seine Wippenachse 42 verschwenken. Der zweite freie Wippenabschnitt 48 wird über das Koppelglied 50 durch das Gewicht des Transportgehänges 60 nach unten bewegt. Der erste freie Wippenabschnitt 46 des Wippengliedes 44 seinerseits drückt durch die nacheilende Gegendruckrolle 30 gegen die untere Lauffläche 34 der Tragschiene 4. Dadurch verringert sich der Abstand zwischen den beiden Drehachsen 21 und 40 der Antriebsrolle 20 bzw. der nacheilenden Gegendruckrolle 30, wodurch sich auch der Abstand der Drehachse 21 der Antriebsrolle 20 zur oberen Lauffläche 18 der Tragschiene 4 verringert und der Anpressdruck der Antriebsrolle 20 gegen die Tragschiene 4 erhöht wird.If the inclination angle of the inclined portion 68 of the support rail 4 assumes a value at which the coupling member 50 so far pivoted about its pivot axis 52 relative to the support surface 64, that its support pin 62 no longer rests on the support surface 64 and in the transport direction 32 over the edge moved out, as can be seen in Figure 4, the now released rocker member 44 can pivot about its rocker axis 42. The second free rocker section 48 is moved via the coupling member 50 by the weight of the transport hanger 60 down. The first free rocker section 46 of the rocker member 44 in turn pushes by the trailing counter-pressure roller 30 against the lower running surface 34 of the support rail 4. This reduces the distance between the two axes of rotation 21 and 40 of the drive roller 20 and the trailing counter-pressure roller 30, which also the Distance of the rotation axis 21 of the drive roller 20 to the upper running surface 18 of the support rail 4 is reduced and the contact pressure of the drive roller 20 is increased against the support rail 4.

Wie in Figur 4 zu erkennen ist, verliert der Auflagebolzen 62 den Kontakt zur Auflagefläche 64 in einem gegenüber einer horizontalen Ebenen nach oben geneigten Abschnitt 68 auf der in Transportrichtung 32 weisenden Seite der Auflagefläche 64 des Tragstutzens 66.As in FIG. 4 can be seen, the support pin 62 loses contact with the support surface 64 in a relation to a horizontal plane upwardly inclined portion 68 on the direction of transport 32 side facing the support surface 64 of the support stub 66th

In Figur 5 ist ein in Transportrichtung 32 gegenüber einer horizontalen Ebene nach unten geneigter Abschnitt 70 der Tragschiene 4 gezeigt, dessen Neigungswinkel größer ist als der Neigungswinkel-Schwellenwert. Wenn sich der Tragwagen 8 in einem solchen Abschnitt 70 befindet, verliert der Auflagebolzen 62 des Koppelgliedes 50 den Kontakt zur Auflagefläche 64 auf der zur Transportrichtung 32 entgegengesetzten Richtung liegenden Seite des Tragstutzens 66. Auch in diesem Fall bewirkt die Gewichtskraft des Transportgehänges 60, dass das Wippenglied 44 um seine Wippenachse 42 verschwenkt wird und sich der Anpressdruck der Antriebsrolle 20 auf die obere Lauffläche 18 der Tragschiene 4 erhöht, indem der Abstand zwischen der Drehachse 40 der nacheilenden Gegendruckrolle 30 und der Tragschiene 4 und damit der Abstand zwischen der Drehachse 21 der Antriebsrolle 20 und der oberen Lauffläche 18 der Tragschiene 4 verringert wird.In FIG. 5 is shown in the transport direction 32 with respect to a horizontal plane downwardly inclined portion 70 of the support rail 4, the inclination angle is greater than the inclination angle threshold. When the wagon 8 is in such a section 70, the support pin 62 of the coupling member 50 loses contact with the support surface 64 in the direction opposite to the transport direction 32 direction Also in this case causes the weight of the Transportgehänges 60 that the rocker member 44 is pivoted about its rocker axis 42 and increases the contact pressure of the drive roller 20 on the upper tread 18 of the support rail 4 by the distance between the axis of rotation 40 of the trailing counter-pressure roller 30 and the support rail 4 and thus the distance between the rotation axis 21 of the drive roller 20 and the upper tread 18 of the support rail 4 is reduced.

Diese Verringerung des Abstands wird bei der oben erläuterten Anpresseinrichtung 38 durch den mit dem Auflagebolzen 62 des Koppelglieds 50 zusammenarbeitenden Tragstutzen 66 jeweils unterbunden, so lange sich der Tragwagen 8 in einem geneigten Abschnitt der Tragschiene 4 befindet, dessen Neigungswinkel kleiner als ein Neigungswinkel-Schwellenwert ist. Erst wenn dieser Neigungswinkel-Schwellenwert erreicht oder überschritten wird, gibt die Auflagefläche 64 des Tragstutzens 66 das Koppelglied 50 frei, so dass das Wippenglied 44 um seine Wippenachse 42 verschwenken kann.This reduction of the distance is prevented in the above-described pressing device 38 by the cooperating with the support bolt 62 of the coupling member 50 support piece 66 each, as long as the wagon 8 is in an inclined portion of the support rail 4, the inclination angle is smaller than a tilt angle threshold , Only when this angle of inclination threshold is reached or exceeded, the support surface 64 of the support sleeve 66 releases the coupling member 50, so that the rocker member 44 can pivot about its rocker axis 42.

Der Neigungswinkel-Schwellenwert, bei welchem das Koppelglied 50 und damit das Wippenglied 44 freigegeben wird, ist durch die Erstreckung der Auflagefläche 64 in Richtung der jeweiligen Verschwenkung des Koppelglieds 50, die bei einer Steigungs- oder Gefällefahrt des Tragwagens 8 erfolgt, vorgegeben. Je größer die Erstreckung der Auflagefläche 64 in eine dieser Richtungen, desto größer kann die Steigung oder das Gefälle der Tragschiene 4 sein, ohne dass der Auflagebolzen 62 des Koppelglieds 50 den Kontakt zur Auflagefläche 64 verliert und das Wippenglied 44 durch das Transportgehänge 60 verschwenkt wird.The angle of inclination threshold at which the coupling member 50 and thus the rocker member 44 is released, is determined by the extension of the support surface 64 in the direction of the respective pivoting of the coupling member 50, which takes place during a gradient or downward travel of the trolley 8. The greater the extent of the support surface 64 in one of these directions, the greater the pitch or the slope of the support rail 4, without the support pin 62 of the coupling member 50 loses contact with the support surface 64 and the rocker member 44 is pivoted by the transport hanger 60.
