Definitions

  • the invention relates to an electronic overhead conveyor with an opposing horizontal running track with I-shaped cross-section and a carrier vehicle movable along this, the carrier vehicle having at least one motor-driven drive roller that rolls on an upper horizontal running surface, with one on the carrier vehicle to compensate for inclinations of the running rail pivotally mounted load slings and at least one pressure roller that can be pressed onto the running rail depending on the angle of inclination of the load sling.
  • Electric monorails are used in particular in the production along assembly lines and for the transport of workpieces.
  • the carrier vehicle and load suspension vehicle parts such as body, engine or the like are moved along the assembly line and transported from one work station to the next and positioned accordingly.
  • the running track along which the electric monorail runs has a multitude of horizontal and vertical curves along the assembly line. While the driving force of the drive roller of the carrier vehicle is completely sufficient for traversing horizontal curves, drive problems arise when traversing vertical curves due to inadequate contact pressure of the drive rollers, that is to say insufficient friction between the running rail and the drive roller.
  • German utility model G 90 03 155 it is therefore proposed to use pressure rollers opposite the drive roller, particularly when Go through vertical curves.
  • the pressure rollers protrude laterally from a carrier pivotally mounted on the carrier vehicle, at the lower end of which the load suspension is pivotably supported.
  • a pressure roller arranged downstream in the direction of travel is pressed against a lower horizontal running surface of the running rail.
  • a disadvantage of the previously known electric monorail system is that the pressure rollers are pressed on not only as a function of the angle of inclination of the load suspension system but also as a function of the load weight.
  • the drive roller With a smaller angle of inclination and a large load, for example, there is a high contact pressure, although with a small angle of inclination the drive roller can move the carrier vehicle along the running rail without additional contact pressure. This leads to increased wear on drive and pressure rollers.
  • the power consumption of the drive must be increased in order to overcome the unnecessarily increased friction between the drive roller and the running rail.
  • the invention is therefore based on the object of improving an electric monorail conveyor of the type mentioned at the outset with a view to controlling a contact pressure exerted by a pressure roller.
  • the bearing lever with the pressure roller rotatably mounted at its upper end is pivoted depending on the angle of inclination by the actuating device in the direction of the running rail and either pressed onto the underside of the upper horizontal running surface opposite the driving roller or against the lower horizontal running surface of the running rail from below.
  • the pressure roller is correspondingly pivoted only slightly and accordingly not pressed against the running rail at all with only a small contact force or depending on the angle of inclination.
  • the pressure roller is pressed onto the running rail essentially independently of the load weight and only as a function of the angle of inclination. In this way, there is sufficient driving force or braking effect of the drive roller in the electric monorail system according to the invention in any case.
  • an axis of rotation of the pressure roller is arranged parallel to the pivot axis of the bearing lever.
  • the pressure roller is pivotally mounted in the direction of travel of the carrier vehicle, whereby the pivoting of the pressure roller against the running rail is simplified.
  • the carrier vehicle has two drive rollers and a load suspension bearing is arranged centrally below the running rail.
  • the use of two drive rollers and the arrangement of the load suspension bearing results in better dynamics of the carrier vehicle with increased stability at the same time.
  • the pressure roller is pressed against the running rail from below, for example, on an incline essentially below the rear drive roller in the direction of travel and on a downhill slope essentially below the front drive roller in the direction of travel.
  • pressure rollers and associated bearing levers are arranged on both sides of the load suspension bearing. In this way, depending on the vertical curve corresponding to the above, the rear or front pressure roller in the direction of travel is pressed against the running surface. It is possible for both pressure rollers to be pressed onto the running surface at the same time using different pressure forces.
  • the pressure roller In order to control the pressure force of the pressure rollers not only by pivoting them onto the running surface, it is furthermore favorable if the pressure roller can be acted upon in the direction of the lower horizontal running surface. In this way, the contact pressure can be adjusted by the actuating device and by the application of force to the contact roller.
  • the load suspension has a load hanger protruding upwards from a load frame, which is pivotably mounted with an upper end on the load suspension bearing.
  • the load hanger is swiveled in accordance with the inclinations of the running rail.
  • the angle of inclination of the load hanger relative to the transport vehicle can be used to control the actuating device and thus to pivot the bearing lever and pressure roller.
  • the actuating device is designed as a spacer which is arranged between the load hanger and the bearing lever and is pivotally supported by its ends on the load hanger and on the bearing lever.
  • the bearing lever is adjusted as a function of the angle of inclination of the load hanger by the predetermined and, if necessary, adjustable length of the spacer.
  • the length of the spacer can be chosen so that, with a small angle of inclination, there is still no pressure on the running surface. Due to the adjustability of the spacer length, it is possible to press against the running surface under changed conditions, such as an increased load weight in the course of the assembly line or in another application area of the electric monorail conveyor, even with a small angle of inclination.
  • the pivot bearing of the spacer on the bearing lever is arranged approximately centrally between the bearing lever pivot bearing and the pressure roller pivot bearing.
  • a pivot bearing pin of the bearing lever is guided at its two ends in a longitudinal groove formed in a load crossbar and is spring-loaded in the direction of the lower horizontal running surface. Due to the guidance and spring loading of the ends of the pivot bearing pin, the bearing lever is pivotably mounted in a simple manner and at the same time is subjected to force in the direction of the running rail.
  • two compression springs are arranged around a vertical guide in each case to act on the spring of the pivot bearing pin.
  • the vertical guide serves to guide the compression springs and to adjust the height of the pivot bearing pin along the longitudinal groove.
  • a downwardly extending receptacle which at least partially surrounds the spring, is arranged at the upper end of the vertical guide and has a bearing opening for mounting the pivot bearing pin.
  • the height adjustment of the pivot bearing pin is coupled in a simple manner with the adjustability of the vertical guides, with force being simultaneously applied in the direction of the running rail by the spring.
  • the bearing lever is pivoted by the adjusting device, the spring is compressed and the contact pressure on the running rail is known dependent on a spring constant and a preload of the spring.
  • height-adjustable and power-loaded other devices such as shock absorber-like devices, hydraulically or pneumatically operated pistons or the like can be used.
  • the receptacle In a favorable embodiment of the receptacle, it is essentially U-shaped, the U-legs laterally surrounding the spring and the bearing opening being formed in a U-web. In this way, the vertical guides and springs are easily accessible for maintenance or replacement.
  • the bearing lever is formed from two side walls which extend essentially parallel to the receptacle, between which a receiving sleeve for the pivot bearing pin and bearing pin for mounting the spacer and pressure roller are arranged.
  • the receiving sleeve and the bearing pin can protrude laterally over the side walls, the bearing lever being essentially surrounded by the load beam.
  • axes of rotation in the carrier vehicle are arranged adjacent to both ends of the carrier vehicle below the running rail, on which a vehicle chassis for pivoting the drive roller and guide rollers is mounted.
  • a drive for the drive roller can also be arranged on the vehicle chassis.
  • the guide rollers are mounted in a known manner on the running frame about vertical axes of rotation and roll on vertical running surfaces of the running rail. These are arranged on both sides of the horizontal running surfaces and face each other on each side of the running rail.
  • a motor is assigned to each drive roller.
  • the motor is, for example, an electric motor, which is supplied by electrical lines laid in the running rail via corresponding sliding contact.
  • At least one precursor is movably arranged on the running rail, which is arranged upstream of the carrier vehicle by means of a connecting rod arranged at a front end of the carrier vehicle in the direction of travel.
  • the distance to a front carrier of the electric monorail system is determined by the forerunner.
  • the distance between two carrier vehicles can be defined by an analogue follower in cooperation with a predecessor of a following carrier vehicle.
  • an electric monorail system in which a running gear is provided with a motor-driven drive wheel and at least one auxiliary wheel which interacts with an auxiliary rail in some areas. Due to the auxiliary wheel rolling on the auxiliary rail drive power is to be transmitted to a running rail, so that up and down gradients can be traversed more easily. By means of interaction with the auxiliary wheel, the pressure force of the drive wheel or roller is increased by the auxiliary rail.
  • the auxiliary track does not perform any other tasks.
  • At least one link is arranged, on which control rollers which roll along an auxiliary rail arranged adjacent to the running rail are rotatably mounted. Due to the forced control of the angle of inclination, an uncontrolled pivoting of the load suspension below the carrier vehicle is prevented, particularly when starting or braking the carrier vehicle.
  • the arrangement of the auxiliary rail is particularly selected so that the load sling and a workpiece carried by it are aligned horizontally regardless of the inclinations of the running rail. This is particularly important if the center of gravity of the load sling changes during movement along an assembly line due to the mounting of additional workpiece parts. Due to the change in the center of gravity, the load suspension can pivot relative to the carrier vehicle, which can hinder further assembly work or the movement of the load suspension along the running rail.
  • an auxiliary rail is arranged on both sides at substantially the same distance from the running rail, control rollers being guided in each auxiliary rail by links projecting from the load suspension device. That way the load sling is supported on both sides and held in its horizontal arrangement.
  • control rollers are rotatably mounted in a rotor which is pivotably mounted vertically and horizontally on the handlebars. Due to the vertical and horizontal swiveling of the runner, cornering is in no way hindered.
  • four support rollers rotatable about a horizontal axis of rotation and four guide rollers rotatable about a vertical axis of rotation can be mounted in the rotor.
  • the idler rollers can roll along an upper surface of a lower horizontal tread of a substantially I-shaped auxiliary rail and the guide rollers can roll along the vertical tread upwardly from the lower horizontal tread.
  • the handlebars protrude rearward from the load suspension device in the direction of travel. It is also possible to stand forward.
  • the handlebars enclose an acute angle and the runners are arranged on the handlebar ends outside a load suspension device contour , so that a sufficiently large free space is formed between the handlebars and runners.
  • this has longitudinal members and cross members, whereby the side members hanging down support for holding a workpiece, such as engine, vehicle body or the like, are pivotally mounted, and the handlebars protrude from a rear cross member and is releasably attached to a front cross member of the load hanger.
  • the angle of inclination can also be reduced.
  • larger inclines can be traversed in this way, in particular with empty load hangers.
  • a collision of the load suspension with a longitudinal or cross member with the running rail is prevented due to a reduction in the angle of inclination by the handlebars.
  • the longitudinal members of the hanger are positively guided out of their horizontal arrangement into an arrangement pivoted closer to the running rail.
  • the actuating device can be designed as an actuating drive which is assigned to a pressure roller, and which can be actuated electrically, pneumatically or hydraulically and which pivots the pressure roller depending on the angle of inclination and / or loading of the load suspension device for pressing against the running rail.
  • the actuators can be actuated on the basis of sensors which measure the angle of inclination and, for example, the load weight. In accordance with the values specified for different angles of inclination and load weights, the pressure rollers can be pressed onto the running rail by pivoting the associated bearing levers.

Description

Die Erfindung betrifft eine Elektronhängebahn mit einer gegenüberliegende horizontale Laufflächen aufweisenden Laufschiene mit I-förmigen Querschnitt und einem entlang dieser bewegbaren Tragfahrzeug, wobei das Tragfahrzeug wenigstens einer auf einer oberen horizontalen Lauffläche rollende, motorbetriebene Antriebsrolle aufweist, mit einem am Tragfahrzeug zum Ausgleich von Neigungen der Laufschiene verschwenkbar gelagerten Lastgehänge und wenigstens einer in Abhängigkeit vom Neigungswinkel des Lastgehänges an die Laufschiene andrückbaren Anpreßrolle.The invention relates to an electronic overhead conveyor with an opposing horizontal running track with I-shaped cross-section and a carrier vehicle movable along this, the carrier vehicle having at least one motor-driven drive roller that rolls on an upper horizontal running surface, with one on the carrier vehicle to compensate for inclinations of the running rail pivotally mounted load slings and at least one pressure roller that can be pressed onto the running rail depending on the angle of inclination of the load sling.

Elektrohängebahnen werden insbesondere bei der Fertigung entlang von Montagelinien und zum Transport von Werkstücken eingesetzt. Beispielsweise bei der Fahrzeugherstellung werden vom Tragfahrzeug und Lastgehänge Fahrzeugteile wie Karosserie, Motor oder dergleichen entlang der Montagelinie fortbewegt und von einer Arbeitsstation zur nächsten transportiert und entsprechend positioniert. Die Laufschiene an der die Elektrohängebahn entlangläuft weist entlang der Montagelinie eine Vielzahl von horizontalen und vertikalen Kurven auf. Während die Vortriebskraft der Antriebsrolle des Tragfahrzeugs zum Durchlaufen von horizontalen Kurven vollständig ausreichend ist, ergeben sich beim Durchlaufen von vertikalen Kurven Antriebsprobleme durch unzureichenden Anpreßdruck der Antriebsrollen, das heißt ungenügende Reibung zwischen Laufschiene und Antriebsrolle.Electric monorails are used in particular in the production along assembly lines and for the transport of workpieces. For example, in vehicle manufacture, the carrier vehicle and load suspension vehicle parts such as body, engine or the like are moved along the assembly line and transported from one work station to the next and positioned accordingly. The running track along which the electric monorail runs has a multitude of horizontal and vertical curves along the assembly line. While the driving force of the drive roller of the carrier vehicle is completely sufficient for traversing horizontal curves, drive problems arise when traversing vertical curves due to inadequate contact pressure of the drive rollers, that is to say insufficient friction between the running rail and the drive roller.

In dem deutschen Gebrauchsmuster G 90 03 155 wird daher vorgeschlagen, mit zur Antriebsrolle gegenüberliegenden Anpreßrollen die Anpreßkraft insbesondere beim Durchlaufen von vertikalen Kurven zu erhöhen. Die Anpreßrollen stehen seitlich von einem an dem Tragfahrzeug verschwenkbar gelagerten Träger ab, an dessem unteren Ende das Lastgehänge verschwenkbar gelagert ist. Je nach Steigung oder Gefälle der Laufschiene in vertikalen Kurven wird eine in Fahrtrichtung nachgeordnete Anpreßrolle an eine untere horizontale Lauffläche der Laufschiene angepreßt.In German utility model G 90 03 155, it is therefore proposed to use pressure rollers opposite the drive roller, particularly when Go through vertical curves. The pressure rollers protrude laterally from a carrier pivotally mounted on the carrier vehicle, at the lower end of which the load suspension is pivotably supported. Depending on the incline or slope of the running rail in vertical curves, a pressure roller arranged downstream in the direction of travel is pressed against a lower horizontal running surface of the running rail.

Nachteilig bei der vorbekannten Elektrohängebahn ist, daß das Anpressen der Anpreßrollen nicht nur in Abhängigkeit vom Neigungswinkel des Lastgehänges sondern auch in Abhängigkeit vom Lastgewicht geschieht. Bei einem kleineren Neigungswinkel und einer großen Last ergibt sich beispielsweise ein hoher Anpreßdruck, obwohl bei einem geringen Neigungswinkel die Antriebsrolle ohne zusätzlichen Anpreßdruck das Tragfahrzeug entlang der Laufschiene fortbewegen kann. Dies führt zu einem erhöhten Verschleiß von Antriebs- und Anpreßrollen. Außerdem muß zum Überwinden der unnötig erhöhten Reibung zwischen Antriebsrolle und Laufschiene die Leistungsaufnahme des Antriebs erhöht werden.A disadvantage of the previously known electric monorail system is that the pressure rollers are pressed on not only as a function of the angle of inclination of the load suspension system but also as a function of the load weight. With a smaller angle of inclination and a large load, for example, there is a high contact pressure, although with a small angle of inclination the drive roller can move the carrier vehicle along the running rail without additional contact pressure. This leads to increased wear on drive and pressure rollers. In addition, the power consumption of the drive must be increased in order to overcome the unnecessarily increased friction between the drive roller and the running rail.

Entsprechend ist bei der vorbekannten Elektrohängebahn bei großem Neigungswinkel und geringem Lastgewicht oder ohne Last nur ein geringer Anpreßdruck gegeben. Dies kann insbesondere bei Leerfahrt der Elektrohängebahn und bei einem großen Neigungswinkel, das heißt einer Laufschiene mit großer Steigung oder Gefälle, zu einem Durchdrehen der Antriebsrolle führen. Auf diese Weise kann bei Steigungsfahrt kein genügender Vortrieb und bei einem Gefälle der Laufschiene keine genügende Bremswirkung gegeben sein.Accordingly, only a small contact pressure is given in the previously known electric monorail system with a large inclination angle and low load weight or without load. This can lead to the drive roller spinning, particularly when the electric monorail conveyor is running empty and when there is a large inclination angle, that is to say a running rail with a large incline or descent. In this way, there can be no sufficient propulsion when driving uphill and no sufficient braking effect when the running track is on a slope.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Elektrohängebahn der eingangs genannten Art im Hinblick auf die Steuerung einer durch eine Anpreßrolle ausgeübten Anpreßkraft zu verbessern.The invention is therefore based on the object of improving an electric monorail conveyor of the type mentioned at the outset with a view to controlling a contact pressure exerted by a pressure roller.

Diese Aufgabe wird bei einer Elektrohängebahn mit den Merkmalen des Oberbegriffs des Anspruchs 1 dadurch gelöst, daß die Anpreßrolle an einem oberen Ende eines mit seinem unteren Ende am Tragfahrzeug verschwenkbar gelagerten Lagerhebels drehbar gelagert ist, welcher zum Verschwenken in Abhängigkeit vom Neigungswinkel mit einer Stelleinrichtung verbunden ist.This object is achieved in an electric monorail system with the features of the preamble of claim 1 in that the pressure roller is rotatably mounted on an upper end of a bearing lever which is pivotably mounted with its lower end on the carrier vehicle and which is connected to an actuating device for pivoting as a function of the angle of inclination .

Aufgrund der Erfindung erfolgt eine Verstellung der Anpreßrollen und damit der Anpreßkraft unabhängig von dem am Lastgehänge wirkenden Lastgewicht. Der Lagerhebel mit der an seinem oberen Ende drehbar gelagerten Anpreßrolle wird in Abhängigkeit vom Neigungswinkel durch die Stelleinrichtung in Richtung zur Laufschiene verschwenkt und entweder an die Unterseite der oberen horizontalen Lauffläche gegenüberliegend zur Antriebsrolle oder an die untere horizontale Lauffläche der Laufschiene von unten angedrückt.Due to the invention, the pressure rollers and thus the pressure force are adjusted independently of the load weight acting on the load suspension. The bearing lever with the pressure roller rotatably mounted at its upper end is pivoted depending on the angle of inclination by the actuating device in the direction of the running rail and either pressed onto the underside of the upper horizontal running surface opposite the driving roller or against the lower horizontal running surface of the running rail from below.

Durchläuft das Tragfahrzeug eine Vertikalkurve mit geringer Neigung wird die Anpreßrolle entsprechend nur wenig verschwenkt und entsprechend nur mit geringer Anpreßkraft oder je nach Neigungswinkel garnicht an die Laufschiene angedrückt. Bei großen Neigungswinkeln wird die Anpreßrolle im wesentlichen unabhängig vom Lastgewicht und nur in Abhängigkeit vom Neigungswinkel an die Laufschiene angedrückt. Auf diese Weise ist in jedem Fall eine ausreichende Antriebskraft beziehungsweise Bremswirkung der Antriebsrolle bei der erfindungsgemäßen Elektrohängebahn gegeben.If the carrier vehicle traverses a vertical curve with a slight inclination, the pressure roller is correspondingly pivoted only slightly and accordingly not pressed against the running rail at all with only a small contact force or depending on the angle of inclination. At large angles of inclination, the pressure roller is pressed onto the running rail essentially independently of the load weight and only as a function of the angle of inclination. In this way, there is sufficient driving force or braking effect of the drive roller in the electric monorail system according to the invention in any case.

Bei einer vorteilhaften Ausführungsform der Erfindung ist eine Drehachse der Anpreßrolle parallel zur Schwenkachse des Lagerhebels angeordnet. Auf diese Weise ist die Anpreßrolle in Fahrtrichtung des Tragfahrzeugs verschwenkbar gelagert, wodurch das Heranschwenken der Anpreßrolle an die Laufschiene vereinfacht ist.In an advantageous embodiment of the invention, an axis of rotation of the pressure roller is arranged parallel to the pivot axis of the bearing lever. In this way, the pressure roller is pivotally mounted in the direction of travel of the carrier vehicle, whereby the pivoting of the pressure roller against the running rail is simplified.

Weiterhin ist von Vorteil, wenn das Tragfahrzeug zwei Antriebsrollen aufweist und ein Lastgehängelager mittig zu diesem unterhalb der Laufschiene angeordnet ist. Durch die Verwendung zweier Antriebsrollen und die Anordnung des Lastgehängelagers ergibt sich eine bessere Dynamik des Tragfahrzeugs bei gleichzeitig erhöhter Stabilität. Die Anpreßrolle wird dabei beispielsweise bei einer Steigungsfahrt im wesentlichen unterhalb der in Fahrtrichtung hinteren Antriebsrolle und bei einer Gefällstrecke im wesentlichen unterhalb der in Fahrtrichtung vorderen Antriebsrolle von unten an die Laufschiene angedrückt.It is also advantageous if the carrier vehicle has two drive rollers and a load suspension bearing is arranged centrally below the running rail. The use of two drive rollers and the arrangement of the load suspension bearing results in better dynamics of the carrier vehicle with increased stability at the same time. The pressure roller is pressed against the running rail from below, for example, on an incline essentially below the rear drive roller in the direction of travel and on a downhill slope essentially below the front drive roller in the direction of travel.

In diesem Zusammenhang ist es weiterhin von Vorteil, wenn beidseitig zum Lastgehängelager Anpreßrollen und zugehörige Lagerhebel angeordnet sind. Auf diese Weise wird je nach Vertikalkurve entsprechend zum Vorstehenden die in Fahrtrichtung hintere oder vordere Anpreßrolle an die Lauffläche angedrückt. Dabei ist es möglich, daß beide Anpreßrollen gleichzeitig mit unterschiedlichen Anpreßkräften an die Lauffläche angedrückt werden.In this context, it is also advantageous if pressure rollers and associated bearing levers are arranged on both sides of the load suspension bearing. In this way, depending on the vertical curve corresponding to the above, the rear or front pressure roller in the direction of travel is pressed against the running surface. It is possible for both pressure rollers to be pressed onto the running surface at the same time using different pressure forces.

Um die Anpreßkraft der Anpreßrollen nicht nur durch deren Verschwenken an die Lauffläche zu steuern, ist es weiterhin günstig, wenn die Anpreßrolle in Richtung zur unteren horizontalen Lauffläche kraftbeaufschlagbar ist. Auf diese Weise ist die Anpreßkraft durch die Stelleinrichtung und durch die Kraftbeaufschlagung der Anpreßrolle einstellbar.In order to control the pressure force of the pressure rollers not only by pivoting them onto the running surface, it is furthermore favorable if the pressure roller can be acted upon in the direction of the lower horizontal running surface. In this way, the contact pressure can be adjusted by the actuating device and by the application of force to the contact roller.

Bei einer vorteilhaften Ausführungsform der Erfindung weist das Lastgehänge einen von einem Lastrahmen nach oben abstehenden Lastaufhänger auf, der mit einem oberen Ende am Lastgehängelager verschwenkbar gelagert ist. Der Lastaufhänger wird entsprechend zu den Neigungen der Laufschiene verschwenkt. Der Neigungswinkel des Lastaufhängers relativ zum Transportfahrzeug ist zur Steuerung der Stelleinrichtung und damit zum Verschwenken von Lagerhebel und Anpreßrolle verwendbar.In an advantageous embodiment of the invention, the load suspension has a load hanger protruding upwards from a load frame, which is pivotably mounted with an upper end on the load suspension bearing. The load hanger is swiveled in accordance with the inclinations of the running rail. The angle of inclination of the load hanger relative to the transport vehicle can be used to control the actuating device and thus to pivot the bearing lever and pressure roller.

Dabei ist es weiterhin von Vorteil, wenn die Stelleinrichtung als zwischen Lastaufhänger und Lagerhebel angeordneter Abstandshalter ausgebildet ist, welcher mit seinen Enden an dem Lastaufhänger und am Lagerhebel verschwenkbar gelagert ist. Durch die vorgegebene und gegebenenfalls einstellbare Länge des Abstandshalters wird der Lagerhebel in Abhängigkeit vom Neigungswinkel des Lastaufhängers verstellt. Die Länge des Abstandshalters kann so gewählt sein, daß bei geringem Neigungswinkel noch kein Andrücken an die Lauffläche erfolgt. Durch die Verstellbarkeit der Abstandshalterlänge ist bei geänderten Bedingungen wie einem erhöhten Lastgewicht im Laufe der Montagelinie oder bei einem anderen Einsatzgebiet der Elektrohängebahn auch bei kleinem Neigungswinkel ein Anpressen an die Lauffläche möglich.It is furthermore advantageous if the actuating device is designed as a spacer which is arranged between the load hanger and the bearing lever and is pivotally supported by its ends on the load hanger and on the bearing lever. The bearing lever is adjusted as a function of the angle of inclination of the load hanger by the predetermined and, if necessary, adjustable length of the spacer. The length of the spacer can be chosen so that, with a small angle of inclination, there is still no pressure on the running surface. Due to the adjustability of the spacer length, it is possible to press against the running surface under changed conditions, such as an increased load weight in the course of the assembly line or in another application area of the electric monorail conveyor, even with a small angle of inclination.

Um eine einfache Verbindung der Abstandshalter am Lagerhebel und eine gute Verstellbarkeit des Lagerhebels aufgrund der unterschiedlichen Neigungswinkel zu erzielen, ist es günstig, wenn das Schwenklager des Abstandhalters am Lagerhebel in etwa mittig zwischen Lagerhebelschwenklager und Anpreßrollendrehlager angeordnet ist.In order to achieve a simple connection of the spacers on the bearing lever and good adjustability of the bearing lever due to the different inclination angles, it is advantageous if the pivot bearing of the spacer on the bearing lever is arranged approximately centrally between the bearing lever pivot bearing and the pressure roller pivot bearing.

Eine einfache Befestigungsmöglichkeit der Abstandshalter am Lastaufhänger ist dadurch gegeben, daß unterhalb des Lastgehängelagers einander gegenüberliegende Aufnahmelaschen zur verschwenkbaren Lagerung der Abstandshalter am Lastaufhänger angeordnet sind.A simple way of fastening the spacers to the load hanger is given by the fact that opposite receiving lugs are arranged below the load suspension bearing for the pivotable mounting of the spacers on the load hanger.

Weiterhin erweist es sich als günstig, wenn ein Schwenklagerbolzen des Lagerhebels an seinen beiden Enden in einer in einer Lasttraverse ausgebildeten Längsnut höhenverstellbar geführt ist und in Richtung zur unteren horizontalen Lauffläche federbeaufschlagt ist. Durch die Führung und Federbeaufschlagung der Enden des Schwenklagerbolzens ist der Lagerhebel in einfacher Weise verschwenkbar gelagert und gleichzeitig in Richtung der Laufschiene kraftbeaufschlagt.Furthermore, it proves to be advantageous if a pivot bearing pin of the bearing lever is guided at its two ends in a longitudinal groove formed in a load crossbar and is spring-loaded in the direction of the lower horizontal running surface. Due to the guidance and spring loading of the ends of the pivot bearing pin, the bearing lever is pivotably mounted in a simple manner and at the same time is subjected to force in the direction of the running rail.

In diesem Zusammenhang ist es weiterhin von Vorteil, wenn zur Federbeaufschlagung des Schwenklagerbolzens zwei Druckfedern um jeweils eine Vertikalführung angeordnet sind. Die Vertikalführung dient zur Führung der Druckfedern sowie zur Höhenverstellung des Schwenklagerbolzens entlang der Längsnut.In this context, it is also advantageous if two compression springs are arranged around a vertical guide in each case to act on the spring of the pivot bearing pin. The vertical guide serves to guide the compression springs and to adjust the height of the pivot bearing pin along the longitudinal groove.

Weiterhin ist dabei von Vorteil, wenn am oberen Ende der Vertikalführung eine sich nach unten erstreckende, die Feder zumindest teilweise umgebende Aufnahme angeordnet ist, die zur Lagerung des Schwenklagerbolzens eine Lageröffnung aufweist. Auf diese Weise ist die Höhenverstellung des Schwenklagerbolzens in einfacher Weise mit der Verstellbarkeit der Vertikalführungen gekoppelt, wobei gleichzeitig eine Kraftbeaufschlagung in Richtung zur Laufschiene durch die Feder erfolgt. Beim Verschwenken des Lagerhebels durch die Stelleinrichtung wird die Feder zusammengedrückt und die Anpreßkraft an die Laufschiene ist in bekannter Weise von einer Federkonstanten und einer Vorspannung der Feder abhängig. Statt der Verwendung von Feder und Vertikalführung sind allgemein bekannte, höhenverstellbare und kraftbeaufschlagbare andere Einrichtungen wie stoßdämpferähnliche Einrichtungen, hydraulisch oder pneumatisch betätigte Kolben oder dergleichen verwendbar.Furthermore, it is advantageous if a downwardly extending receptacle, which at least partially surrounds the spring, is arranged at the upper end of the vertical guide and has a bearing opening for mounting the pivot bearing pin. In this way, the height adjustment of the pivot bearing pin is coupled in a simple manner with the adjustability of the vertical guides, with force being simultaneously applied in the direction of the running rail by the spring. When the bearing lever is pivoted by the adjusting device, the spring is compressed and the contact pressure on the running rail is known dependent on a spring constant and a preload of the spring. Instead of the use of spring and vertical guide, generally known, height-adjustable and power-loaded other devices such as shock absorber-like devices, hydraulically or pneumatically operated pistons or the like can be used.

Bei einer günstigen Ausführungsform der Aufnahme ist diese im wesentlichen U-förmig ausgebildet, wobei die U-Schenkel die Feder seitlich umgeben und in einem U-Steg die Lageröffnung ausgebildet ist. Auf diese Weise sind die Vertikalführungen und Federn leicht zur Wartung oder zum Austausch zugänglich.In a favorable embodiment of the receptacle, it is essentially U-shaped, the U-legs laterally surrounding the spring and the bearing opening being formed in a U-web. In this way, the vertical guides and springs are easily accessible for maintenance or replacement.

Dabei ist es weiterhin von Vorteil, wenn untere Enden von Feder- und Vertikalführung an einer mit der Lasttraverse verschraubbaren Abschlußplatte lösbar befestigt sind.It is also advantageous if the lower ends of the spring and vertical guide are releasably attached to an end plate which can be screwed to the load crossbar.

Um in einfacher Weise Vertikalführung und Aufnahme seitlich bei deren Höhenbewegung zu führen, ist es günstig, wenn an der Lasttraverse Führungen für die Aufnahme angeordnet sind.In order to easily guide the vertical guide and receptacle laterally during their height movement, it is expedient if guides for the receptacle are arranged on the load crossmember.

Bei einer einfachen Ausführungsform der Erfindung ist der Lagerhebel aus zwei sich im wesentlichen parallel zur Aufnahme erstreckenden Seitenwänden gebildet, wobei zwischen diesen eine Aufnahmehülse für den Schwenklagerbolzen und Lagerbolzen zur Lagerung von Abstandshalter und Anpreßrolle angeordnet sind. Aufnahmehülse und Lagerbolzen können seitlich über die Seitenwände hervorstehen, wobei der Lagerhebel im wesentlichen von der Lasttraverse umgeben ist.In a simple embodiment of the invention, the bearing lever is formed from two side walls which extend essentially parallel to the receptacle, between which a receiving sleeve for the pivot bearing pin and bearing pin for mounting the spacer and pressure roller are arranged. The receiving sleeve and the bearing pin can protrude laterally over the side walls, the bearing lever being essentially surrounded by the load beam.

Insbesondere für Fahren entlang Horizontalkurven ist es von Vorteil, wenn benachbart zu beiden Enden des Tragfahrzeugs unterhalb der Laufschiene Drehachsen im Tragfahrzeug angeordnet sind, an denen ein Fahrzeugchassis zur Lagerung von Antriebsrolle und Führungsrollen verschwenkbar gelagert ist. Auf dem Fahrzeugchassis kann zusätzlich ein Antrieb für die Antriebsrolle angeordnet sein. Die Führungsrollen sind in bekannter Weise um vertikale Drehachsen drehbar am Laufrahmen gelagert und rollen an vertikalen Laufflächen der Laufschiene ab. Diese sind beidseitig zu den horizontalen Laufflächen angeordnet und weisen auf jeder Seite der Laufschiene aufeinander zu. Zum getrennten Antrieb der Antriebsrollen ist es weiterhin von Vorteil, wenn jeder Antriebsrolle ein Motor zugeordnet ist. Der Motor ist beispielsweise ein Elektromotor, der über entsprechende Schleifkontakt von in der Laufschiene verlegten elektrischen Leitungen versorgt wird.In particular for driving along horizontal curves, it is advantageous if axes of rotation in the carrier vehicle are arranged adjacent to both ends of the carrier vehicle below the running rail, on which a vehicle chassis for pivoting the drive roller and guide rollers is mounted. A drive for the drive roller can also be arranged on the vehicle chassis. The guide rollers are mounted in a known manner on the running frame about vertical axes of rotation and roll on vertical running surfaces of the running rail. These are arranged on both sides of the horizontal running surfaces and face each other on each side of the running rail. For separate drive of the drive rollers, it is also advantageous if a motor is assigned to each drive roller. The motor is, for example, an electric motor, which is supplied by electrical lines laid in the running rail via corresponding sliding contact.

Bei einer Weiterbildung der Erfindung ist wenigstens ein Vorläufer auf der Laufschiene beweglich angeordnet, welcher mittels einer an einem in Fahrtrichtung vorderen Ende des Tragfahrzeugs angeordneten Verbindungsstange dem Tragfahrzeug vorgeordnet ist. Durch den Vorläufer ist der Abstand zu einem vorderen Tragfahrzeug der Elektrohängebahn festgelegt. Entsprechend kann durch einen analogen Nachläufer in Zusammenwirkung mit einem Vorläufer eines nachfolgenden Tragfahrzeugs der Abstand zweier Tragfahrzeuge festgelegt sein.In a further development of the invention, at least one precursor is movably arranged on the running rail, which is arranged upstream of the carrier vehicle by means of a connecting rod arranged at a front end of the carrier vehicle in the direction of travel. The distance to a front carrier of the electric monorail system is determined by the forerunner. Correspondingly, the distance between two carrier vehicles can be defined by an analogue follower in cooperation with a predecessor of a following carrier vehicle.

Aus der EP 0384223 ist eine Elektrohängebahn bekannt, bei der ein Fahrwerk mit einem motorbetriebenen Antriebsrad und zumindest einem mit einer Hilfsschiene bereichsweise wechselwirkenden Hilfsrad versehen ist. Aufgrund des auf der Hilfsschiene rollenden Hilfsrad soll Antriebskraft auf eine Laufschiene übertragen werden, so daß Steigungen und Gefälle problemloser durchfahren werden können. Durch die Hilfsschiene wird durch Wechselwirkung mit dem Hilfsrad die Andruckkraft des Antriebrades beziehungsweise -rolle erhöht. Andere Aufgaben übernimmt die Hilfsschiene nicht.From EP 0384223 an electric monorail system is known in which a running gear is provided with a motor-driven drive wheel and at least one auxiliary wheel which interacts with an auxiliary rail in some areas. Due to the auxiliary wheel rolling on the auxiliary rail drive power is to be transmitted to a running rail, so that up and down gradients can be traversed more easily. By means of interaction with the auxiliary wheel, the pressure force of the drive wheel or roller is increased by the auxiliary rail. The auxiliary track does not perform any other tasks.

Im Gegensatz dazu wird bei einer vorteilhaften Weiterbildung der Erfindung zur Zwangssteuerung des Neigungswinkels am Lastgehänge wenigstens ein Lenker angeordnet, an welchem entlang einer benachbart zur Laufschiene angeordneten Hilfsschiene abrollende Steuerrollen drehbar gelagert sind. Durch die Zwangssteuerung des Neigungswinkels wird insbesondere beim Anfahren beziehungsweise beim Abbremsen des Tragfahrzeugs ein unkontrolliertes Schwenken der Lastaufhängung unterhalb des Tragfahrzeugs unterbunden. Die Anordnung der Hilfsschiene ist insbesondere so ausgewählt, daß das Lastgehänge und ein von ihr mitgeführtes Werkstück unabhängig von Neigungen der Laufschiene horizontal ausgerichtet ist.Dies ist insbesondere wichtig, wenn der Schwerpunkt des Lastgehänges sich während der Fortbewegung entlang einer Montagelinie durch Montieren weiterer Werkstückteile verändert. Aufgrund der Veränderung des Schwerpunkts kann sich das Lastgehänge gegenüber dem Tragfahrzeug verschwenken, was weitere Montagearbeiten oder die Bewegung des Lastgehänges entlang der Laufschiene behindern kann.In contrast to this, in an advantageous further development of the invention for forcibly controlling the angle of inclination on the load suspension device, at least one link is arranged, on which control rollers which roll along an auxiliary rail arranged adjacent to the running rail are rotatably mounted. Due to the forced control of the angle of inclination, an uncontrolled pivoting of the load suspension below the carrier vehicle is prevented, particularly when starting or braking the carrier vehicle. The arrangement of the auxiliary rail is particularly selected so that the load sling and a workpiece carried by it are aligned horizontally regardless of the inclinations of the running rail. This is particularly important if the center of gravity of the load sling changes during movement along an assembly line due to the mounting of additional workpiece parts. Due to the change in the center of gravity, the load suspension can pivot relative to the carrier vehicle, which can hinder further assembly work or the movement of the load suspension along the running rail.

Dabei ist es weiterhin günstig, wenn beidseitig zur Laufschiene in im wesentlichen gleichem Abstand jeweils eine Hilfsschiene angeordnet ist, wobei in jeder Hilfsschiene Steuerrollen von vom Lastgehänge abstehenden Lenkern geführt sind. Auf diese Weise wird das Lastgehänge beidseitig abgestützt und in seiner horizontalen Anordnung gehalten.It is furthermore advantageous if an auxiliary rail is arranged on both sides at substantially the same distance from the running rail, control rollers being guided in each auxiliary rail by links projecting from the load suspension device. That way the load sling is supported on both sides and held in its horizontal arrangement.

Um Kurvenfahrten entlang horizontaler und vertikaler Kurven zu vereinfachen, ist es weiterhin günstig, wenn die Steuerrollen in einem am Lenker vertikal und horizontal verschwenkbar gelagerten Läufer drehbar gelagert sind. Durch die vertikale und horizontale Verschwenkbarkeit des Läufers sind Kurvenfahrten in keiner Weise behindert. In dem Läufer können beispielsweise vier um eine horizontale Drehachse drehbare Tragrollen und vier um eine vertikale Drehachse drehbare Führungsrollen gelagert sein. Die Tragrollen können entlang einer Oberseite einer unteren horizontalen Lauffläche einer im wesentlichen I-förmigen Hilfsschiene rollen und die Führungsrollen können entlang der von der unteren horizontalen Lauffläche nach oben weisenden vertikalen Lauffläche rollen.In order to simplify cornering along horizontal and vertical curves, it is furthermore advantageous if the control rollers are rotatably mounted in a rotor which is pivotably mounted vertically and horizontally on the handlebars. Due to the vertical and horizontal swiveling of the runner, cornering is in no way hindered. For example, four support rollers rotatable about a horizontal axis of rotation and four guide rollers rotatable about a vertical axis of rotation can be mounted in the rotor. The idler rollers can roll along an upper surface of a lower horizontal tread of a substantially I-shaped auxiliary rail and the guide rollers can roll along the vertical tread upwardly from the lower horizontal tread.

Bei einer Ausführungsform der Erfindung stehen die Lenker in Fahrtrichtung nach hinten vom Lastgehänge ab. Entsprechend ist auch ein Abstehen nach vorne möglich.In one embodiment of the invention, the handlebars protrude rearward from the load suspension device in the direction of travel. It is also possible to stand forward.

Um durch die vom Lastgehänge abstehenden Lenker die Zugänglichkeit zum transportieren Werkstück oder zum Beispiel bei einem Fahrzeug ein Öffnen von Heckklappe oder Motorklappe zu ermöglichen, ist es weiterhin von Vorteil, wenn die Lenker einen spitzen Winkel einschließen und die Läufer an Lenkerenden außerhalb einer Lastgehängekontur angeordnet sind, so daß zwischen Lenkern und Läufern ein ausreichend großer Freiraum gebildet ist.In order to enable access to the workpiece being transported or, for example, a vehicle, to open the tailgate or engine flap due to the handlebars projecting from the load suspension device, it is also advantageous if the handlebars enclose an acute angle and the runners are arranged on the handlebar ends outside a load suspension device contour , so that a sufficiently large free space is formed between the handlebars and runners.

Bei einer einfachen Ausführungsform des Lastgehänges weist dieses Längsträger und Querträger auf, wobei an den Längsträgern nach unten hängende Halteträger zum Halten eines Werkstücks, wie Motor, Fahrzeugkarosserie oder dergleichen, verschwenkbar gelagert sind, und von einem hinteren Querträger die Lenker abstehen und an einem vorderen Querträger der Lastaufhänger lösbar befestigt ist.In a simple embodiment of the load suspension device, this has longitudinal members and cross members, whereby the side members hanging down support for holding a workpiece, such as engine, vehicle body or the like, are pivotally mounted, and the handlebars protrude from a rear cross member and is releasably attached to a front cross member of the load hanger.

Weiterhin sei angemerkt, daß aufgrund der Anordnung der obenstehend erwähnten Hilfsschienen auch der Neigungswinkel verkleinert werden kann. Beispielsweise bei einer Steigungsfahrt sind insbesondere bei leeren Lastgehängen auf diese Weise größere Steigungen durchfahrbar. Eine Kollision des Lastgehänges mit einem Längs- oder Querträger mit der Laufschiene wird aufgrund einer Verringerung des Neigungswinkels durch die Lenker verhindert. Die Längsträger des Gehänges sind aufgrund dessen aus ihrer horizontalen Anordnung in eine näher zur Laufschiene verschwenkten Anordnung zwangsgeführt.Furthermore, it should be noted that due to the arrangement of the auxiliary rails mentioned above, the angle of inclination can also be reduced. For example, in the case of an incline run, larger inclines can be traversed in this way, in particular with empty load hangers. A collision of the load suspension with a longitudinal or cross member with the running rail is prevented due to a reduction in the angle of inclination by the handlebars. Because of this, the longitudinal members of the hanger are positively guided out of their horizontal arrangement into an arrangement pivoted closer to the running rail.

Anstelle einer mechanischen Stelleinrichtung kann bei einer weiteren Ausführungsform der Erfindung die Stelleinrichtung als einer Anpreßrolle zugeordneter, elektrisch, pneumatisch oder hydraulisch betätigbarer Stelltrieb ausgebildet sein, welcher die Anpreßrolle in Abhängigkeit vom Neigungswinkel und/oder Beladung des Lastgehänges zum Anpressen an die Laufschiene verschwenkt. Eine Betätigung der Stelltriebe kann aufgrund von Sensoren erfolgen, die den Neigungswinkel und beispielsweise das Lastgewicht messen. Entsprechend zu für verschiedene Neigungswinkel und Lastgewichte vorgegebene Werte sind die Anpreßrollen durch Verschwenken der zugehörigen Lagerhebel an die Laufschiene anpreßbar.In a further embodiment of the invention, instead of a mechanical actuating device, the actuating device can be designed as an actuating drive which is assigned to a pressure roller, and which can be actuated electrically, pneumatically or hydraulically and which pivots the pressure roller depending on the angle of inclination and / or loading of the load suspension device for pressing against the running rail. The actuators can be actuated on the basis of sensors which measure the angle of inclination and, for example, the load weight. In accordance with the values specified for different angles of inclination and load weights, the pressure rollers can be pressed onto the running rail by pivoting the associated bearing levers.

Die erfindungsgemäß vorgeschlagenen Lösungen und vorteilhafte Ausführungsbeispiele davon werden im folgenden anhand der in der Zeichnung dargestellten Figuren weiter erläutert und beschrieben.The solutions proposed according to the invention and advantageous exemplary embodiments thereof are further explained and described below with reference to the figures shown in the drawing.

In Figur 1 ist die erfindungsgemäße Elektrohängebahn 1 in einer Seitenansicht dargestellt. Eine Fahrzeugkarosserie 83 ist mittels eines an einem Tragfahrzeug 5 schwenkbar aufgehängten Lastgehänges 7 in Fahrtrichtung 78 entlang einer Laufschiene 4 bewegbar. Die Laufschiene 4 weist eine obere und eine untere horizontale Lauffläche 2 und 3 auf. Die Laufflächen 2 und 3 sind mit konstantem Abstand zueinander angeordnet. Auf der Lauffläche 2 rollen Antriebsrollen 16 und 6 des Tragfahrzeugs 5. Die Antriebsrollen 6 und 16 sind in festem Abstand zueinander angeordnet und jeder Antriebsrolle ist ein Motor 69 nachgeordnet. Motor und Antriebsrolle sind jeweils an einem Fahrzeugchassis 66 beziehungsweise 67 gehaltert. Die Antriebsrollen 6 und 16 sind um horizontale Drehachsen drehbar in den Fahrzeugchassis 66 beziehungsweise 67 gelagert.In Figure 1, the electric monorail 1 according to the invention is shown in a side view. A vehicle body 83 can be moved in the direction of travel 78 along a running rail 4 by means of a load suspension device 7 which is pivotably suspended on a carrier vehicle 5. The running rail 4 has an upper and a lower horizontal running surface 2 and 3. The treads 2 and 3 are arranged at a constant distance from one another. Drive rollers 16 and 6 of the carrier vehicle 5 roll on the running surface 2. The drive rollers 6 and 16 are arranged at a fixed distance from one another and a motor 69 is arranged after each drive roller. The engine and drive roller are each supported on a vehicle chassis 66 and 67, respectively. The drive rollers 6 and 16 are rotatably mounted about horizontal axes of rotation in the vehicle chassis 66 and 67, respectively.

Die Fahrzeugchassis 66 und 67 umgeben die Laufschiene 4 einseitig und sind unterhalb der unteren Lauffläche 3 durch Drehachsen 62 und 65 verschwenkbar an einer Lasttraverse 33 gelagert. Diese weist in etwa eine M-Form auf, wobei die seitlichen M-Schenkel von der Laufschiene 4 nach unten weisen und eine zwischen diesen angeordnete M-Spitze ein Lastgehängelager 17 des Lastgehänges 7 aufnimmt. In etwa an den Verbindungspunkten von M-Schenkeln und M-Spitze ist jeweils eine Anpreßrolle 9 beziehungsweise 18 angeordnet, die um horizontale Drehachsen 14 drehbar gelagert sind. Das Lastgehängelager 17 ist in etwa mittig zwischen den Antriebsrollen 6 und 16 beziehungsweise den Anpreßrollen 9 und 18 angeordnet.The vehicle chassis 66 and 67 surround the running rail 4 on one side and are pivotably supported on a load crossbeam 33 below the lower running surface 3 by axes of rotation 62 and 65. This has an approximately M-shape, the lateral M-legs pointing downward from the running rail 4 and an M-tip arranged between them receiving a load suspension bearing 17 of the load suspension 7. At approximately the connection points of the M-legs and the M-tip, a pressure roller 9 or 18 is arranged, which is rotatably mounted about horizontal axes of rotation 14. The load suspension bearing 17 is arranged approximately centrally between the drive rollers 6 and 16 or the pressure rollers 9 and 18.

An den seitlich von den M-Schenkeln in Fahrtrichtung 78 beziehungsweise entgegengesetzt zur Fahrtrichtung 78 überstehenden Enden 62 und 63 sind die Drehachsen 64 und 65 verdrehbar gelagert. Direkt benachbart zu diesen sind an den Enden 62 beziehungsweise 63 Verbindungsstangen 71 um eine vertikale Achse verschwenkbar zwischen jeweils zwei Lagerlaschen gelagert. Die in Fahrtrichtung 78 weisende Verbindungsstange 71 erstreckt sich bis zu einem dem Tragfahrzeug 5 vorgeordneten Vorläufer 70. An diesem ist die Verbindungsstange 71 befestigt. Der Vorläufer 70 weist einen die Laufschiene 4 oben und unten und auf einer Seite einschließenden Rahmen auf, an dem eine Anzahl von Tragrollen 85 und Führungsrollen 86 drehbar gelagert sind. Eine Tragrolle ist auf der oberen Lauffläche 2 und zwei Tragrollen sind in Anlage mit der unteren Lauffläche 3 angeordnet. Beidseitig zur oberen Lauffläche 2 sind auf deren Seitenflächen Führungsrollen 86 angeordnet, von denen in Figur 1 nur eine dargestellt ist. Auf den Seitenflächen der unteren Laufflächen 3 sind jeweils zwei Führungsrollen 86 angeordnet, von denen in Figur 1 nur zwei dargestellt sind. Die jeweils nichtdargestellten Führungsrollen sind auf der anderen Seite der Laufschiene 4 angeordnet.The axes of rotation 64 and 65 are rotatably mounted on the ends 62 and 63 projecting laterally from the M legs in the direction of travel 78 or opposite to the direction of travel 78. Directly adjacent to them, connecting rods 71 are mounted at the ends 62 and 63, respectively, pivotable about a vertical axis between two respective mounting brackets. The connecting rod 71 pointing in the direction of travel 78 extends to a forerunner 70 arranged upstream of the carrier vehicle 5. The connecting rod 71 is fastened to this. Of the Forerunner 70 has a frame enclosing the running rail 4 at the top and bottom and on one side, on which a number of support rollers 85 and guide rollers 86 are rotatably mounted. A support roller is on the upper tread 2 and two support rollers are arranged in contact with the lower tread 3. Guide rollers 86 are arranged on both sides of the upper running surface 2, only one of which is shown in FIG. 1. On the side surfaces of the lower running surfaces 3, two guide rollers 86 are arranged, only two of which are shown in FIG. 1. The respective guide rollers, not shown, are arranged on the other side of the running rail 4.

Die entgegengesetzt zur Fahrtrichtung 78 gerichtete Verbindungsstange 71 ist an einem Nachläufer 93 befestigt, der spiegelbildlich zum Vorläufer 70 ausgebildet ist. Sowohl Vorläufer 70 als auch Nachläufer 93 sind im wesentlichen im gleichen Abstand vom Lastgehängelager 17 angeordnet.The connecting rod 71, which is directed opposite to the direction of travel 78, is fastened to a follower 93, which is embodied as a mirror image of the precursor 70. Both forerunner 70 and follower 93 are arranged at substantially the same distance from the load bearing 17.

Am Lastgehängelagerpunkt 17 ist das Lastgehänge 7 mittels eines Lastaufhängers 21 angehängt. Dessen oberes Ende 22 ist am Lastgehängelager 17 verschwenkbar gelagert. Mit seinem unteren Ende ist der Lastaufhänger 21 an einem vorderen Querträger 84 eines Lastrahmens 20 drehbar gelagert.The load suspension 7 is attached to the load suspension bearing point 17 by means of a load suspension device 21. Its upper end 22 is pivotally mounted on the load suspension bearing 17. With its lower end, the load hanger 21 is rotatably mounted on a front cross member 84 of a load frame 20.

Der Lastrahmen 20 umfaßt weiterhin einen hinteren Querträger 81 und zwei die Querträger an ihren Enden verbindende Längsträger 80. In den Längsträgern ist eine Welle zum Verschwenken von an deren Enden befestigten Halteträgern 82 drehbar gelagert. Vorderer und hinterer Halteträger erstrecken sich von einem an der Welle befestigten Lagerpunkt 92 bis zu an ihren anderen Ende angeordneten Haltenasen 89, die die Fahrzeugkarosserie 83 untergreifen. Der vordere Halteträger verläuft im wesentlichen in Vertikalrichtung 88. Der hintere Halteträger verläuft zum Öffnen von Fahrzeugtüren nach hinten und außen gekrümmt. An seinem oberen Ende steht ein Stellhebel 91 zur gemeinsamen Verstellung beider Halteträger vom Lagerpunkt 92 in Richtung Laufschiene 4 ab.The load frame 20 further comprises a rear cross member 81 and two longitudinal members 80 connecting the cross members at their ends. In the longitudinal members, a shaft for pivoting holding members 82 fastened at their ends is rotatably mounted. The front and rear support brackets extend from a bearing point 92 attached to the shaft to its other end arranged holding lugs 89 which engage under the vehicle body 83. The front support bracket extends essentially in the vertical direction 88. The rear support bracket is curved rearward and outward for opening vehicle doors. At its upper end there is an adjusting lever 91 for the joint adjustment of the two support brackets from the bearing point 92 in the direction of the running rail 4.

Die Längsträger 80 des Lastrahmens 20 sind entsprechend zur Laufschiene 4 in horizontaler Richtung 87 ausgerichtet. Vom hinteren Querträger 81 steht ein Lenker 72 nach hinten ab. An seinem freien Lenkerende 79 ist ein Läufer 77 um eine Horizontalachse 94 und eine Vertikalachse 95 sowohl horizontal als auch vertikal verschwenkbar gelagert. In Figur 1 sind zwei am Läufer 77 drehbar gelagerte Steuerrollen 75 sichtbar, die auf der Oberseite einer unteren Lauffläche einer Hilfsschiene 73 aufstehen. Die Hilfsschiene 73 ist unterhalb der Laufschiene 4 und wie später beschrieben wird seitlich versetzt zu dieser angeordnet.The longitudinal beams 80 of the load frame 20 are aligned correspondingly to the running rail 4 in the horizontal direction 87. A link 72 projects from the rear cross member 81 to the rear. At its free handlebar end 79, a runner 77 is mounted so that it can pivot about a horizontal axis 94 and a vertical axis 95 both horizontally and vertically. In Figure 1, two control rollers 75 rotatably mounted on the rotor 77 are visible, which stand on the top of a lower running surface of an auxiliary rail 73. The auxiliary rail 73 is located below the running rail 4 and, as described later, is laterally offset from it.

Der Lenker 72 steht vom hinteren Querträger 81 schräg nach hinten ab, wobei eine Heckklappe 90 der Fahrzeugkarosserie 83 am Lenker 72, Läufer 77 und Hilfsschiene 73 vorbei verschwenkbar ist.The handlebar 72 protrudes obliquely backwards from the rear crossmember 81, a tailgate 90 of the vehicle body 83 being pivotable past the handlebar 72, rotor 77 and auxiliary rail 73.

In Figur 2 sind Tragfahrzeug 5 und Lastgehänge 7 aus Figur 1 vergrößert und detailliert dargestellt, wobei die Laufschiene 4 in Fahrtrichtung 78 in einem Steigungsabschnitt dargestellt ist. Gleiche Bezugszeichen kennzeichnen in Figur 2 wie auch in den folgenden Figuren gleiche Teile und werden nur noch teilweise erwähnt.In FIG. 2, the carrier vehicle 5 and load suspension 7 from FIG. 1 are shown enlarged and in detail, the running rail 4 being shown in an upward section in the direction of travel 78. The same reference numerals designate the same parts in FIG. 2 as in the following figures and are only mentioned in part.

In den Fahrzeugchassis 66 und 67 sind Führungsrollen 68 um vertikale Drehachsen drehbar gelagert und rollen auf Seitenflächen der unteren horizontalen Lauffläche 3. In dem parallel zur Lauffläche 3 angeordneten Fahrzeugchassisträger sind sowohl die Drehlager der Führungsrollen 68 als auch die Drehachsen 64 beziehungsweise 65 angeordnet. Diese sind in etwa mittig zu den Führungsrollen 68 angeordnet und erstrecken sich bis unterhalb der Lasttraverse 33. Direkt benachbar zu diesen sind vorderes Ende 62 beziehungsweise hinteres Ende 63 des Tragfahrzeugs angeordnet, an denen die Verbindungsstangen 71 sowohl in horizontaler als auch vertikaler Richtung verdrehbar gelagert sind.In the vehicle chassis 66 and 67, guide rollers 68 are rotatably mounted about vertical axes of rotation and roll on side surfaces of the lower horizontal running surface 3. In the vehicle chassis arranged parallel to the running surface 3, both the pivot bearings of the guide rollers 68 and the axes of rotation 64 and 65 are arranged. These are arranged approximately in the middle of the guide rollers 68 and extend below the load beam 33. Directly adjacent to this are the front end 62 and rear end 63 of the carrier vehicle, on which the connecting rods 71 are rotatably mounted both in the horizontal and in the vertical direction .

Aufgrund der Neigung der Laufschiene 4 beziehungsweise unteren Lauffläche 3 ist Lastaufhänger 21 um einen Neigungswinkel 8 aus der zur Lauffläche 3 vertikalen Stellung im Lastgehängelager 17 verschwenkt. Der Lastaufhänger 21 ist im wesentlichen zylindrisch ausgebildet, wobei sein oberes Ende 22 einen in etwa quadratischen Querschnitt aufweist. An seinem unteren Ende ist der Lastaufhänger 21 unterhalb des vorderen Querträgers 84 in einer in diesem angeordneten Lagerhülse 96 angeordnet. Der Lastträger 21 ist drehbar in der Lagerhülse 96 gelagert.Due to the inclination of the running rail 4 or lower running surface 3, load hanger 21 is pivoted by an angle of inclination 8 from the position in the load suspension bearing 17 that is vertical to the running surface 3. The load hanger 21 is essentially cylindrical, its upper end 22 having an approximately square cross section. At its lower end, the load hanger 21 is arranged below the front cross member 84 in a bearing sleeve 96 arranged therein. The load carrier 21 is rotatably supported in the bearing sleeve 96.

In etwa mittig zwischen dem oberen Ende der Lagerhülse 96 und dem oberen Ende 22 des Lastaufhängers 21 stehen von diesem beidseitig in horizontaler Richtung Aufnahmelaschen 31 und 32 ab. Diese sind durch jeweils zwei beabstandete Lagerflansche gebildet, zwischen denen ein Ende 26 beziehungsweise 27 eines Abstandshalters 23 beziehungsweise 24 verschwenkbar gelagert ist. Die Abstandshalter 23 und 24 legen den Abstand zwischen Aufnahmelaschen 31 und 32 und Lagerhebeln 19 fest. Diese sind relativ zu den M-Schenkeln der Lasttraverse 33 um Schwenkachsen 15 verschwenkbar gelagert. Die Abstandshalter 23 und 24 sind mit ihren anderen Enden 25 beziehungsweise 28 in etwa mittig zwischen der jeweiligen Schwenkachse 15 am unteren Ende des linken Lagerhebels 19 beziehungsweise rechten, nicht dargestellten Lagerhebels und einer Drehachse 14 für Anpreßrollen 18 beziehungsweise 9 am oberen Ende der entsprechenden Lagerhebel verschwenkbar an diesen gelagert.Approximately in the middle between the upper end of the bearing sleeve 96 and the upper end 22 of the load hanger 21, receiving tabs 31 and 32 protrude from it on both sides in the horizontal direction. These are each formed by two spaced-apart bearing flanges, between which one end 26 or 27 of a spacer 23 or 24 is pivotally mounted. The spacers 23 and 24 place the distance between Receiving tabs 31 and 32 and bearing levers 19 firmly. These are mounted so that they can pivot about pivot axes 15 relative to the M legs of the load beam 33. The spacers 23 and 24 can be pivoted with their other ends 25 and 28 approximately centrally between the respective pivot axis 15 at the lower end of the left bearing lever 19 or right bearing lever, not shown, and an axis of rotation 14 for pressure rollers 18 and 9 at the upper end of the corresponding bearing lever stored on these.

Der linke Lagerhebel 19 ist gegenüber dem M-Schenkel der Lasttraverse 33 entgegengesetzt zur Fahrtrichtung 78 verschwenkt, wobei die Anpreßrolle 18 nicht mit der Lauffläche 3 in Anlage ist. Der rechte Lagerhebel verläuft in etwa parallel zum anderen M-Schenkel der Lasttraverse 33, wobei die Anpreßrolle 9 von unten auf der Lauffläche 3 aufsteht.The left bearing lever 19 is pivoted opposite to the M-leg of the load crossbar 33 in the opposite direction to the direction of travel 78, the pressure roller 18 not being in contact with the running surface 3. The right bearing lever runs approximately parallel to the other M-leg of the load cross member 33, the pressure roller 9 standing on the running surface 3 from below.

Die Abstandshalter 23 beziehungsweise 24 mit ihren entsprechenden Lagerende 25 und 26 beziehungsweise 27 und 28 bilden eine Stelleinrichtung 13 zum Verschwenken der Anpreßrollen 9 beziehungsweise 18 in Abhängigkeit vom Neigungswinkel 8.The spacers 23 and 24 with their corresponding bearing ends 25 and 26 or 27 and 28 form an adjusting device 13 for pivoting the pressure rollers 9 and 18 depending on the angle of inclination 8.

Wie im folgenden genauer beschrieben wird, sind die Lagerhebel mit ihren Schwenkachsen 15 an einer Aufnahme 44 beziehungsweise 45 verschwenkbar gelagert. Die entlang der M-Schenkel der Lasttraverse 33 angeordneten Einrichtung, wie beispielsweise die Aufnahmen 44 und 45, sind jeweils gleichartig ausgebildet, so daß die Beschreibung auf die Einrichtungen an einem M-Schenkel beschränkt werden kann.As will be described in more detail below, the pivot levers 15 are pivotably supported on their receptacles 44 and 45, respectively. The device arranged along the M-leg of the load beam 33, such as the receptacles 44 and 45, are each of the same design, so that the description can be limited to the devices on an M-leg.

Die Aufnahme 44, 45 ist mittels einer Vertikalführung 40, 41 und einer Druckfeder 38, 39 entlang der Lasttraverse 33 beweglich gelagert. Ein oberes Ende 42, 43 der Vertikalführung 40, 41 ist durch ein oberes Ende der Aufnahme 44, 45 hindurchgeführt. Ein unteres Ende 51 der Vertikalführung ist durch eine Abschlußplatte 52, 53 hindurchgeführt, die von unten an der Lasttraverse 33 am Ende der M-Schenkel angeordnet ist. Die Feder 38, 39 ist konzentrisch zur Vertikalführung 40, 41 angeordnet, umgibt diese zwischen ihren Enden 51 und 42, 43 und drückt Aufnahme 44, 45 und Abschlußplatte 52, 53 auseinander.The receptacle 44, 45 is movably mounted along the load cross member 33 by means of a vertical guide 40, 41 and a compression spring 38, 39. An upper end 42, 43 of the vertical guide 40, 41 is passed through an upper end of the receptacle 44, 45. A lower end 51 of the vertical guide is passed through an end plate 52, 53, which is arranged from below on the load beam 33 at the end of the M-leg. The spring 38, 39 is arranged concentrically to the vertical guide 40, 41, surrounds it between its ends 51 and 42, 43 and presses receptacle 44, 45 and end plate 52, 53 apart.

Zur Führung der Aufnahmen 44 und 45 entsprechend zu Verkürzungen oder Verlängerungen der Vertikalführungen 40, 41 sind beidseitig zu den Aufnahmen Führungen 54 und 55 angeordnet. Diese weisen einen rechteckförmigen Querschnitt auf, wobei eine längere Rechteckseite mit geringem Abstand zur Aufnahme 44, 45 angeordnet ist. Die Führungen 54 und 55 stehen senkrecht zur Zeichnungsebene von der Lasttraverse 33 ab.Guides 54 and 55 are arranged on both sides of the receptacles for guiding the receptacles 44 and 45 corresponding to shortening or extending the vertical guides 40, 41. These have a rectangular cross section, a longer rectangular side being arranged at a short distance from the receptacle 44, 45. The guides 54 and 55 protrude perpendicularly to the plane of the drawing from the load beam 33.

In Figur 3 sind die in Figur 2 rechts vom Lastaufhänger 21 angeordnete Vertikalführung 41 und die entsprechenden zugehörigen Teile vergrößert dargestellt.In FIG. 3, the vertical guide 41 arranged on the right of the load hanger 21 in FIG. 2 and the corresponding associated parts are shown enlarged.

Am unteren Ende 11 ist der Lagerhebel 12 im Lagerhebelschwenklager 29 um Schwenkachse 15 mittels eines Schwenklagerbolzens 35 schwenkbar gelagert. In etwa mittig zwischen Lagerhebelschwenklager 29 und Anpreßrollendrehlager 30 ist das Ende 28 des Abstandshalters 24 verschwenkbar am Lagerhebel 12 gelagert. Alle drei vorstehend genannten Lager sind mit ihren Drehachsen auf einer Symmetrieachse in Längsrichtung des Lagerhebels 12 angeordnet.In Figure 3, the pressure roller 9 is shown in its position at an inclination angle of Figure 2 of approximately 0 °. At the upper end 10 of the bearing lever 12, the pressure roller 9 is rotatably mounted in the pressure roller pivot bearing 30 about the axis of rotation 14. At the lower end 11, the bearing lever 12 is pivotally mounted in the bearing lever pivot bearing 29 about pivot axis 15 by means of a pivot bearing bolt 35. Approximately in the middle between the bearing lever pivot bearing 29 and the pressure roller pivot bearing 30 the end 28 of the spacer 24 is pivotally mounted on the bearing lever 12. All three bearings mentioned above are arranged with their axes of rotation on an axis of symmetry in the longitudinal direction of the bearing lever 12.

Schwenklagerbolzen 35 ist in der Lasttraverse 33 in einer Längsnut 34 höhenverschieblich gelagert. In der in Figur 3 dargestellten Stellung des Lagerhebels 12 ist der Schwenklagerbolzen 35 nahe dem halbkreisförmigen oberen Ende der Längsnut 34 angeordnet.Die Längsnut 34 ist an ihrem unteren Ende zum Ausbau der Stelleinrichtung 13 offen.Pivot bearing pin 35 is mounted in the load cross member 33 in a longitudinal groove 34 so that it can be displaced in height. In the position of the bearing lever 12 shown in FIG. 3, the pivot bearing pin 35 is arranged near the semicircular upper end of the longitudinal groove 34. The longitudinal groove 34 is open at its lower end for removing the adjusting device 13.

Die Aufnahme 45 ist im wesentlichen U-förmig ausgebildet, wobei ein U-Steg 50 parallel und mit geringem Abstand zur Außenseite der Lasttraverse 33 angeordnet ist. Die U-Schenkel 48 und 49 stehen senkrecht vom U-Steg 50 ab und erstrecken sich in Figur 3 aus der Zeichenebene.

Zwischen Abschlußplatte 53 und Deckplatte 103 ist konzentrisch zur Vertikalführung 41 die Feder 39 angeordnet. Diese ist im Bereich der Aufnahme 45 innerhalb dieser angeordnet. Die Aufnahme 45 überdeckt mit ihrem unteren Ende das Lagerhebelschwenklager 29, wobei das Führungsrohr 100 aus der Aufnahme 45 nach unten hervorsteht. Nahe ihrem oberen Ende ist die Aufnahme 45 von den beidseitig zu ihr angeordneten Führung 54 und 55 in Höhenrichtung geführt.The receptacle 45 is essentially U-shaped, a U-web 50 being arranged in parallel and at a short distance from the outside of the load beam 33. The U-legs 48 and 49 protrude perpendicularly from the U-web 50 and extend in Figure 3 from the plane of the drawing. U-legs 48 and 49 and U-web 50 are connected to one another at their upper ends by a cover plate 103. The upper end 43 of the vertical guide 41 is screwed to the cover plate 103. The vertical guide 41 comprises a guide pin 100, it forms the upper end 43 of the vertical guide 41, and a spacer tube 99 arranged below the guide pin 100. A spindle 102 is arranged within the spacer tube, which is inserted into the guide pin 100 to change the pretension of the spring 39 - and can be unscrewed. The vertical guide 41 is slidably mounted with its lower end 51 in the end plate 53 and with its upper end 43 in an opening in the cover plate 103. The upper end 43 is designed as a stop with a radially projecting stop flange for the spring-loaded receptacle 45. At the lower end 51 is a washer as a stop arranged.

In Figur 6 ist eine Vorderansicht auf die in Figur 1 dargestellte Fahrzeugkarosserie 83 dargestellt. Die Laufschiene 4 und seitlich zu dieser angeordnete Hilfsschienen 73 und 74 sind im Schnitt dargestellt. Alle Schienen sind im Querschnitt I-förmig. Auf der oberen horizontalen Lauffläche der Laufschiene 4 ist das Antriebsrad 16 angeordnet. Dieses ist über ein Radlager 111 mit einem Motor 69 antriebsverbunden. Seitlich zur oberen Lauffläche sind Führungsrollen 68 angeordnet, die auf den Seitenflächen der oberen Lauffläche rollen. Entsprechend sind auf den Seitenflächen der unteren Lauffläche beidseitig Führungsrollen 68 angeordnet. Alle Führungsrollen 68 sowie die Antriebsrolle 16 sind an dem Fahrzeugchassis 66 drehbar gelagert. Unterhalb der Laufschiene 4 ist die Drehachse 64 angeordnet, mittels der das Fahrzeugchassis 66 gegenüber dem unterhalb der Laufschiene 4 angeordneten Teil des Tragfahrzeugs verschwenkbar ist. Einseitig zur Laufschiene 4 ist ein Aufhängebügel 118 angeordnet. Dieser ist in etwa U-förmig ausgebildet und dient zur Aufhängung der Schiene.FIG. 6 shows a front view of the vehicle body 83 shown in FIG. 1. The Track 4 and auxiliary rails 73 and 74 arranged laterally to it are shown in section. All rails are I-shaped in cross-section. The drive wheel 16 is arranged on the upper horizontal running surface of the running rail 4. This is drive-connected to a motor 69 via a wheel bearing 111. Guide rollers 68 are arranged laterally to the upper running surface and roll on the side surfaces of the upper running surface. Correspondingly, guide rollers 68 are arranged on both sides of the side surfaces of the lower running surface. All guide rollers 68 and the drive roller 16 are rotatably mounted on the vehicle chassis 66. The axis of rotation 64 is arranged below the running rail 4, by means of which the vehicle chassis 66 can be pivoted relative to the part of the carrier vehicle arranged below the running rail 4. A suspension bracket 118 is arranged on one side of the running rail 4. This is approximately U-shaped and is used to hang the rail.

In Verlängerung der Laufschiene 4 nach unten ist der Lastaufhänger 21 angeordnet. Dieser ist mit seinem unteren Ende im Querträger 84 drehbar gelagert. Der Querträger 84 erstreckt sich zwischen Längsträgern 80 die an seinen beiden Enden angeordnet sind. Um eine in den Längsträgern 80 gelagerte Welle sind die Halteträger 82 verschwenkbar gelagert. In einer ersten Stellung sind beidseitig die Halteträger 82 mit ihren aufeinander zuweisenden Haltenasen 89 unterhalb der Fahrzeugkarosserie 83 angeordnet. In einer zweiten Stellung sind die Halteträger 82 von der Fahrzeugkarosserie 83 nach außen fortgeschwenkt. Die Haltenasen 89 sind seitlich von der Fahrzeugkarosserie 83 angeordnet, so daß diese nicht mehr auf den Haltenasen aufliegt.The load hanger 21 is arranged in the downward extension of the running rail 4. This is rotatably supported with its lower end in the cross member 84. The cross member 84 extends between side members 80 which are arranged at its two ends. The holding supports 82 are pivotably mounted around a shaft mounted in the longitudinal supports 80. In a first position, the holding brackets 82 with their holding lugs 89 facing one another are arranged below the vehicle body 83 on both sides. In a second position, the holding brackets 82 are pivoted outward from the vehicle body 83. The holding lugs 89 are arranged on the side of the vehicle body 83 so that it no longer rests on the holding lugs.

Zur Verstellung der Halteträger 82 ist mit ihrer Lagerwelle ein sich oberhalb der Längsträger 80 erstreckender Stellhebel 91 verbunden. Dieser weist an seinem oberen Ende eine Kontaktrolle 115 auf. Gerät diese mit einer an einer Auslenkschiene 110 angeordneten Führung 114 in Kontakt sind die Halteträger 82 durch aufeinander zugekrümmte, beidseitig zur Laufschiene 4 angeordnete Führungen in ihre von der Fahrzeugkarosserie 83 fortgeschwenkte Stellung verschwenkbar.To adjust the holding bracket 82, an adjusting lever 91 extending above the longitudinal bracket 80 is connected to its bearing shaft. This has a contact roller 115 at its upper end. If this device comes into contact with a guide 114 arranged on a deflection rail 110, the holding carriers 82 can be pivoted into their position pivoted away from the vehicle body 83 by guides which are curved towards one another and arranged on both sides of the running rail 4.

Seitlich versetzt zur Laufschiene 4 und unterhalb dieser sind mit jeweils gleichem Abstand Hilfsschienen 73 und 74 angeordnet. Diese sind im Vergleich zur Laufschiene 4 mit geringerer Höhe ausgebildet. Beide Hilfsschiene 73 und 74 weisen einen im wesentlichen I-förmigen Quersschnitt auf. Auf einer Oberseite einer unteren Lauffläche der Hilfsschienen 73 und 74 sind an den Läufern 77 eine Anzahl von Tragrollen 85 drehbar gelagert. Weiterhin sind an den Läufern 77 auf den Seitenflächen der unteren Lauffläche rollende Führungsrollen 86 beidseitig zu den Hilfsschiene 73 und 74 angeordnet. Direkt unterhalb der Führungsrollen 86 ist eine horizontale Achse 112 zur vertikalen Verschwenkbarkeit der Lenker 72 gegenüber den Läufern 77 angeordnet. Diese ist um eine vertikale Achse 113 in horizontaler Richtung verschwenkbar an den Lenkern 72 gelagert. Die Lenker 72 erstrecken sich vom hinteren Querträger aus Figur 1 seitlich über die Längsträger 80 hinaus, so daß sie über die Außenkontur des Lastgehänges 7 vorstehen. Entsprechend sind die Hilfsschienen 73 und 74 außerhalb der Außenkontur des Lastgehänges 7 angeordnet, so daß die Heckklappe 90 nach Figur 1 der Fahrzeugkarosserie 83 nach oben verschwenkbar ist.Laterally offset to the running rail 4 and below this, auxiliary rails 73 and 74 are arranged with the same spacing in each case. These are designed with a lower height than the running rail 4. Both auxiliary rails 73 and 74 have an essentially I-shaped cross section. A number of support rollers 85 are rotatably mounted on the runners 77 on an upper side of a lower running surface of the auxiliary rails 73 and 74. Furthermore, guide rollers 86 are arranged on both sides of the auxiliary rails 73 and 74 on the runners 77 on the side surfaces of the lower running surface. A horizontal axis 112 is arranged directly below the guide rollers 86 for the vertical pivotability of the links 72 relative to the runners 77. This is pivotally mounted on the links 72 about a vertical axis 113 in the horizontal direction. The links 72 extend laterally from the rear cross member from FIG. 1 beyond the longitudinal members 80, so that they protrude beyond the outer contour of the load suspension device 7. Correspondingly, the auxiliary rails 73 and 74 are arranged outside the outer contour of the load suspension device 7, so that the tailgate 90 of FIG. 1 of the vehicle body 83 can be pivoted upward.

In Figur 7 ist eine Elektrohängebahn 1 entlang einer Montagelinie für Fahrzeugkarosserien dargestellt. Eine Vielzahl von Tragfahrzeugen 5 mit Lastgehängen 7 sind hintereinander entlang der Laufschiene 4 angeordnet. Die Laufschiene 4 verläuft in Figur 7 in einem festen Abstand über einer Bodenfläche. Daran schließt sich ein nach unten versetzter Abschnitt der Laufschiene an, in dem die Fahrzeugkarosserie 83 in Richtung eines Förderbandes 116 absenkbar ist. Nach Freigabe der Fahrzeugkarosserie durch ein nach außen Verschwenken der Halteträger 82, wie es in Figur 6 beschrieben ist, sind die Fahrzeugkarosserien 83 auf dem Förderband 116 abgesetzt. Darauffolgend krümmt sich die Laufschiene 4 nach oben und verläuft nach dem Steigungsabschnitt wieder in einem festen Abstand zur Bodenfläche beziehungsweise zum Förderband 116. Nach Absetzen der Fahrzeugkarosserie 83 sind die Lastgehänge 7, die sich entlang der Laufschiene 4 bewegen, leer. Am Ende des oberen horizontalen Abschnitts der Laufschiene 4 durchläuft diese eine Horizontalkurve von im wesentlichen 90°. Dadurch sind die Tragfahrzeuge und Lastgehänge 5 und 7 ebenfalls um 90° verschwenkt, so daß die Hilfsschiene 73 und 74 unterhalb der Laufschiene 4 sichtbar sind.FIG. 7 shows an electric monorail 1 along an assembly line for vehicle bodies. A large number of carrier vehicles 5 with load slings 7 are arranged one behind the other along the running rail 4. The running rail 4 runs in FIG. 7 at a fixed distance above a floor surface. This is followed by a downwardly offset section of the running rail, in which the vehicle body 83 can be lowered in the direction of a conveyor belt 116. After the vehicle body has been released by pivoting the support bracket 82 outwards, as described in FIG. 6, the vehicle bodies 83 are deposited on the conveyor belt 116. Subsequently, the running rail 4 curves upwards and, after the slope section, runs again at a fixed distance from the floor surface or from the conveyor belt 116. After the vehicle body 83 has been set down, the load hangers 7 which move along the running rail 4 are empty. At the end of the upper horizontal section of the running rail 4, it runs through a horizontal curve of essentially 90 °. Characterized the carrier vehicles and load suspension 5 and 7 are also pivoted by 90 °, so that the auxiliary rails 73 and 74 are visible below the running rail 4.

Die Hilfsschienen 73 und 74 verlaufen jeweils in gleicher Höhe und parallel zueinander. In den horizontalen Abschnitten zu Beginn der in Figur 7 dargestellten Laufschiene 4 und an derem Ende sind die Hilfsschienen jeweils unterhalb der Laufschiene 4 angeordnet. Der Abstand von Laufschiene 4 und Hilfsschienen 73 und 74 ist so gewählt, daß entsprechend zum Abstand der Antriebsrollen 6 und 16 und der als Steuerrollen 75 ausgebildeten Tragrollen 85 gemäß Figur 1 und 6 einer Horizontalstellung des Lastgehänges 7 gegeben ist. Entsprechend zu Neigungen der Laufschiene 4 durchlaufen die Hilfsschienen 73 und 74 bei einer Steigung entsprechende Neigungen zu einem früheren Zeitpunkt. Zum Absenken der Fahrzeugkarosserie 83 verläuft die Hilfsschiene vor der Laufschiene 4 nach unten. Zum Abheben und Entfernen der Lastgehänge 7 nach Absetzen der Fahrzeugkarosserie ist die Hilfsschiene vor der Laufschiene 4 nach oben geneigt und geht entsprechend vor dieser in eine horizontale Anordnung über. Da in Figur 7 leere Lastgehänge 7 nach oben abtransportierbar sind, sind diese durch eine entsprechende Anordnung der Hilfsschienen nicht in ihrer horizontal ausgerichtet, sondern weisen einen kleineren Neigungswinkel 8 als beladene Lastgehänge auf. Der relative Verlauf von Hilfsschienen 73 und 74 und Laufschiene 4 ergibt sich durch die im allgemeinen erwünschte horizontale Anordnung des Lastgehänges 7 und durch den Abstand zwischen Lastaufhänger 21 und Lenkerenden 79 gemäß Figur 1. Je größer dieser Abstand ist, desto früher müssen die Hilfsschienen vor Vertikalkurven der Laufschiene entsprechende Vertikalkurven aufweisen.The auxiliary rails 73 and 74 each run at the same height and parallel to each other. In the horizontal sections at the beginning of the running rail 4 shown in FIG. 7 and at the end thereof, the auxiliary rails are each arranged below the running rail 4. The distance from the running rail 4 and the auxiliary rails 73 and 74 is selected such that corresponding to the distance between the drive rollers 6 and 16 and the support rollers 85 designed as control rollers 75 according to FIG 1 and 6 a horizontal position of the load suspension 7 is given. Corresponding to inclinations of the running rail 4, the auxiliary rails 73 and 74 pass through corresponding inclinations at an earlier point in the case of an incline. To lower the vehicle body 83, the auxiliary rail runs downwards in front of the running rail 4. To lift and remove the load slings 7 after the vehicle body has been set down, the auxiliary rail in front of the running rail 4 is inclined upward and merges accordingly into a horizontal arrangement in front of the latter. Since empty load slings 7 can be transported upward in FIG. 7, these are not aligned horizontally by a corresponding arrangement of the auxiliary rails, but instead have a smaller angle of inclination 8 than loaded load slings. The relative course of the auxiliary rails 73 and 74 and the running rail 4 results from the generally desired horizontal arrangement of the load suspension 7 and from the distance between the load hanger 21 and the handlebar ends 79 according to FIG have vertical curves corresponding to the running track.

Zwischen den leeren Lastgehängen 7 und den auf dem Förderband 116 abtransportierten Karosserien 83 ist als Schutz eine Schutzdecke oder ein Schutznetz 117 angeordnet.A protective blanket or protective net 117 is arranged as protection between the empty load hangers 7 and the bodies 83 transported away on the conveyor belt 116.
