Alternatively or additionally, the rail vehicle has at least one rechargeable energy storage unit, in particular at least one supercapacitor. The energy storage unit is used for power supply in situations in which, for example, due to a loss of contact with the current-carrying rails and / or in sections without power supply rails, an external power supply is interrupted. This ensures that short, pulse-like power supply interruptions do not already trigger emergency braking.
In vorteilhaften Ausgestaltungen umfasst das Schienenfahrzeug eine zentrale Steuereinheit zur Steuerung der Antriebsvorrichtung. Beispielsweise umfasst die Antriebsvorrichtung in einer Ausgestaltung mehrere, jeweils einem Achsmodul zugeordnete Antriebseinheiten, wobei mittels jeder Antriebseinheit ein oder zwei Laufelemente des Achsmoduls angetrieben werden.

Das Schienentransportsystem 1 umfasst eine Laufschiene 2 und mindestens ein entlang der Laufschiene 2 selbsttätig bewegbares, fahrerloses Schienenfahrzeug 3. Vorzugsweise sind mehrere Schienenfahrzeuge 3 vorgesehen. Das dargestellte Schienentransportsystem 1 wird auch als Monoschienensystem bezeichnet, da die Schienenfahrzeuge 3 entlang nur einer Laufschiene 2 bewegt werden. 1 and 2 schematically show a part of a rail transport system 1 for production, assembly and / or logistics processes in a perspective view and a side view. The rail transport system 1 comprises a running rail 2 and at least one automatically movable along the running rail 2, driverless rail vehicle 3. Preferably, a plurality of rail vehicles 3 are provided. The illustrated rail transport system 1 is also referred to as a monorail system, since the rail vehicles 3 are moved along only one running rail 2.
Das in den Fig. 1 und 2 dargestellte Schienenfahrzeug 3 umfasst zwei Achsmodule 31 , 32 die in Längsrichtung mittels einer Trägerplatte 30 verbunden sind. Die dargestellten Achsmodule 31 , 32 haben jeweils zwei beidseits der Laufschiene 2 anzuordnende Seitenteile 310, 320, von welchen in den Fig. 1 und 2 jeweils nur eines sichtbar ist. Die Seitenteile 310, 320 sind dabei ebenfalls über die Trägerplatte 30 miteinander verbunden. Die Trägerplatte 30 ist alternativ zu der in den Fig. 1 und 2 dargestellten Anordnung auch an einer Unterseite der Seitenteile 310, 320 und somit unterhalb der Laufschiene 2 anordenbar. In jedem Seitenteil 310, 320 ist ein Laufelement vorgesehen, wobei das Schienenfahrzeug 3 mittels der Laufelemente an der Laufschiene 2 abgestützt ist. Die Laufelemente sind für eine Bewegung des Schienenfahrzeugs 3 entlang der Laufschiene 2 zumindest teilweise angetrieben. The rail vehicle 3 shown in FIGS. 1 and 2 comprises two axle modules 31, 32 which are connected in the longitudinal direction by means of a carrier plate 30. The illustrated axle modules 31, 32 each have two side parts 310, 320 to be arranged on both sides of the running rail 2, of which only one is visible in FIGS. 1 and 2. The side parts 310, 320 are likewise connected to one another via the carrier plate 30. As an alternative to the arrangement shown in FIGS. 1 and 2, the carrier plate 30 can also be arranged on an underside of the side parts 310, 320 and thus below the running rail 2.

The running elements are at least partially driven for movement of the rail vehicle 3 along the running rail 2.
Die Achsmodule 31 , 32 sind in einer Ausgestaltung zumindest im Wesentlichen baugleich. In anderen Ausgestaltungen unterscheiden sich die Achsmodule 31 , 32 in ihrem Aufbau, wobei beispielsweise nur ein Achsmodul 31 , 32 ein für eine Bewegung des Schienenfahrzeugs angetriebenes Laufelement aufweist. The axle modules 31, 32 are in one embodiment at least substantially identical. In other embodiments, the axle modules 31, 32 differ in their construction, wherein, for example, only one axle module 31, 32 has a driven for a movement of the rail vehicle running element.
Das Schienenfahrzeug 3 ist selbsttätig mittels der Laufelemente und einer an dem Schienenfahrzeug 3 vorgesehenen, in den Figuren nicht sichtbaren Antriebsvorrichtung bewegbar. Die Antriebsvorrichtung umfasst mindestens eine Antriebseinheit zum Antrieb mindestens eines Laufelements, vorzugsweise mehrere dezentral angeordnete den Laufelementen zugeordnete Antriebseinheiten. Als Antriebseinheit ist vorzugsweise ein Elektromotor vorgesehen. Eine An- Steuerung der Antriebsvorrichtung erfolgt vorzugsweise mittels einer an dem Schienenfahrzeug 3 vorgesehen, zentralen Steuereinheit. Für eine Energieversorgung der Antriebsvorrichtung und/oder der zentralen Steuereinheit sind an einer Seite der Laufschiene 2 zwei parallel verlaufende Stromführungsschienen 4 vorgesehen. An dem Schienenfahrzeug 3 sind nicht sichtbare Stromabnehmer vorgesehen, welche mit den Stromführungsschienen 4 zusammenwirken. Die Stromabnehmer sind beispielsweise wie in DE 198 37 975 A1 beschrieben gestaltet. An einer Oberseite der Laufschiene 2 ist eine Abdeckleiste 5 vorgesehen. The rail vehicle 3 is automatically movable by means of the running elements and provided on the rail vehicle 3, not visible in the figures drive device.

For a power supply of the drive device and / or the central control unit 2, two parallel current guide rails 4 are provided on one side of the running rail. On the rail vehicle 3 not visible pantographs are provided, which cooperate with the power guide rails 4. The current collectors are designed, for example, as described in DE 198 37 975 A1. At an upper side of the running rail 2, a cover strip 5 is provided.
Das dargestellte Schienenfahrzeug 3 weist weiter zwei Notbremssysteme 6 auf. In dem dargestellten Ausführungsbeispiel sind zwei den Achsmodulen 31 , 32 zugeordnete Notbremssysteme 6 vorgesehen, welche jeweils einen mechanischen Schalter 60 umfassen, wobei beide Notbremssysteme 6 mittels der mechanischen Schalter 60 aktivierbar sind. In anderen Ausgestaltungen sind beide Notbremssysteme 6 mittels eines gemeinsamen Schalters aktivierbar. In wieder anderen Ausgestaltungen ist nur ein Notbremssystem 6 vorgesehen. Die Funktion der Notbremssysteme 6 wird weiter unten im Detail erläutert. The illustrated rail vehicle 3 further comprises two emergency braking systems 6. In the illustrated embodiment, two the axis modules 31, 32 associated emergency braking systems 6 are provided, each comprising a mechanical switch 60, both emergency braking systems 6 are activated by means of the mechanical switch 60. In other embodiments, both emergency braking systems 6 can be activated by means of a common switch. In still other embodiments, only one emergency brake system 6 is provided. The function of the emergency brake systems 6 will be explained in detail below.
An den zwei Enden der Trägerplatte 30 ist jeweils ein Aufprall-Schutzelement 36 vorgesehen, welches in Längsrichtung verschieblich mit der Trägerplatte 30 gekoppelt ist. Die Aufprall- Schutzelemente 36 sind plattenförmig gestaltet und vorzugsweise entgegen der Kraft geeigneter Rückstellelemente (nicht sichtbar) verstellbar. Die Aufprall-Schutzelemente 36 dienen dabei als Feder- und/oder Dämpfungsanordnung zur Reduzierung der bei einer Kollision mit einem zweiten Schienenfahrzeug 3 oder der Umgebung auftretenden Kräfte. Zudem sind vorzugsweise Sensoren vorgesehen, mittels welchen eine Verschiebung eines Aufprall-Schutzelements 36 relativ zu der Trägerplatte 30 erfassbar ist, sodass bei einer Verschiebung das Notbremssystem 6 aktivierbar ist. At the two ends of the support plate 30, an impact protection element 36 is provided in each case, which is coupled in the longitudinal direction displaceable with the support plate 30. The impact protection elements 36 are designed plate-shaped and preferably against the force of suitable restoring elements (not visible) adjustable. The impact protection elements 36 serve as a spring and / or damping arrangement for reducing the forces occurring in the event of a collision with a second rail vehicle 3 or the environment. In addition, sensors are preferably provided by means of which a displacement of an impact protection element 36 relative to the support plate 30 can be detected, so that the emergency brake system 6 can be activated during a displacement.
Weiter weist das dargestellte Schienenfahrzeug 2 mehrere Sensorelemente 8 auf, mittels welcher Hindernisse in der Bewegungsbahn des Schienenfahrzeugs 2 detektierbar sind. Die Sensorelemente 8 sind in dem dargestellten Ausführungsbeispiel an den Aufprall-Schutzelementen 36 angeordnet. Furthermore, the illustrated rail vehicle 2 has a plurality of sensor elements 8, by means of which obstacles in the trajectory of the rail vehicle 2 can be detected. The sensor elements 8 are arranged in the illustrated embodiment of the impact protection elements 36.
Die Seitenteile 310, 320 umfassen jeweils Abdeckungen, wobei die Abdeckungen derart gestaltet sind, dass zwischen den Seitenteile 310, 320 und damit zwischen dem Schienenfahrzeug 3 und der Laufschiene 2 ein Spalt verbleibt, der vorzugsweise kleiner als 5 mm ist. Die Abdeckungen sind in vorteilhaften Ausgestaltungen in ihrer Position relativ zu der Laufschiene verschiebbar, so dass der Abstand zu jedem Zeitpunkt eine maximale Spaltgröße, beispielsweise 5 mm nicht überschreitet und gleichzeitig vermieden wird, dass die Abdeckungen beim Durchfah- ren von Kurven oder dergleichen an die Laufschiene anstoßen. Zu diesem Zweck sind in einer Ausgestaltung nicht dargestellte federbelastete Andrückelemente vorgesehen, wobei die Abdeckungen mittels der Andrückelemente abgestützt sind. Dadurch wird eine Verletzungsgefahr durch Einklemmen vermieden. Außerdem kann dadurch auf Schutzgitter oder Einhausungen des Transportsystems verzichtet werden. The side parts 310, 320 each comprise covers, wherein the covers are designed such that a gap, which is preferably smaller than 5 mm, remains between the side parts 310, 320 and thus between the rail vehicle 3 and the running rail 2. The covers are in advantageous embodiments in position relative to the track displaced, so that the distance at any time a maximum gap size, for example, 5 mm does not exceed and at the same time is avoided that the covers when passing through. ren of curves or the like to the running rail abut. For this purpose, not shown in a design spring-loaded pressure elements are provided, wherein the covers are supported by means of the pressing elements. As a result, a risk of injury by trapping is avoided. In addition, this can be dispensed with protective grid or enclosures of the transport system.
Eine Strecke der Laufschiene 2 ist an den jeweiligen Produktions-, Montage- und/oder Logistik- prozess angepasst, wobei die Strecke je nach Anforderung Weichen oder Abzweigungen aufweisen kann. Die Steuereinheit weist in vorteilhaften Ausgestaltungen ein Kommunikationsmodul auf, über welches Weichen individuell ansteuerbar sind. Die Strecke ist aus mehreren in Reihe angeordneten Laufschienen-Profilelementen 20 (s. Fig. 3), kurz Profilelementen, zusammengesetzt. A track of the track 2 is adapted to the respective production, assembly and / or logistics process, wherein the route may have switches or branches as required. In advantageous embodiments, the control unit has a communication module via which switches can be controlled individually. The track is composed of several series-arranged track profile elements 20 (see Fig. 3), short profile elements.
Wie am besten anhand des in Fig. 3 dargestellten Querschnitts eines Laufschienen- Profilelements 20 erkennbar ist, ist das Profilelement 20 bezüglich einer Mittellinie 21 symmetrisch aufgebaut. Die Laufschiene 2, genauer das Profilelement 20 hat beidseits der Mittellinie 21 jeweils eine nach oben weisende Laufbahn 22, wobei die Laufbahnen 22 zumindest im Wesentlichen in einer Höhe angeordnet sind. Weiter sind beidseits der Mittellinie 20 jeweils eine obere vertikale Führungsbahn 23, die oberhalb der Laufbahnen 22 angeordnet ist, und eine untere vertikale Führungsbahn 24, die unterhalb der Laufbahnen 22 angeordnet ist, vorgesehen. As can best be seen from the cross section of a rail profile element 20 shown in FIG. 3, the profile element 20 is constructed symmetrically with respect to a center line 21. The running rail 2, more precisely the profile element 20 has on both sides of the center line 21 each have an upwardly facing track 22, wherein the raceways 22 are arranged at least substantially at a height. Further, on both sides of the center line 20 are each an upper vertical guide track 23, which is arranged above the raceways 22, and a lower vertical guide track 24, which is arranged below the raceways 22, is provided.
Das Profilelement 20 ist im Wesentlichen umgekehrt T-förmig. Die Laufbahnen 22 sind an der Oberseite eines ersten Abschnitts 201 vorgesehen, welcher in dem dargestellten Ausführungsbeispiel den Querbalken der umgekehrten T-Form an einem unteren Ende des Profilelements 20 bildet. Der erste Abschnitt 201 ragt somit beidseits der Mittellinie 21 seitlich ab. Die zwei unteren Führungsbahn 24 sind an den zwei Seitenflächen des ersten Abschnitts 201 vorgesehen. The profile element 20 is substantially inverted T-shaped. The raceways 22 are provided at the top of a first portion 201, which forms the transverse bar of the inverted T-shape at a lower end of the profile element 20 in the illustrated embodiment. The first section 201 thus protrudes laterally on both sides of the center line 21. The two lower guide tracks 24 are provided on the two side surfaces of the first section 201.
Das Profilelement 20 weist weiter sechs T-Nuten 25 auf, in welche teilweise die in Fig. 1 und 2 dargestellten Stromführungsschienen 4 eingeclipst werden. In dem dargestellten Ausführungsbeispiel sind die T-Nuten 25 für die Stromführungsschienen 4 an einem zweiten, zu dem ersten Abschnitt 201 in vertikaler Richtung beabstandeten Abschnitt 202 des Profilelements 20 vorgesehen. Dabei sind in dem dargestellten Ausführungsbeispiel an beiden Seiten des Profilelements 20 jeweils drei T-Nuten 25 vorgesehen, wobei vorzugsweise in zwei, an einer Seite angeordnete T-Nuten 25 im Gebrauch die Stromführungsschienen 4 eingeclipst werden. The profile element 20 further has six T-slots 25, in which partially the power guide rails 4 shown in FIGS. 1 and 2 are clipped. In the illustrated embodiment, the T-slots 25 are provided for the current-carrying rails 4 at a second, spaced apart from the first portion 201 in the vertical direction portion 202 of the profile element 20. In this case, three T-slots 25 are provided in the illustrated embodiment on both sides of the profile element 20, wherein preferably in two, arranged on one side T-slots 25 in use, the power guide rails 4 are clipped.
Der erste Abschnitt 201 und der zweite Abschnitt 202 sind über einen vertikalen Steg 26 verbunden, dessen Breite in Richtung auf den ersten Abschnitt 201 zunimmt. Die zwei oberen Führungsbahnen 23 sind oberhalb der T-Nuten 25 an den zwei Seitenflächen des zweiten Abschnitts 202 vorgesehen. The first section 201 and the second section 202 are connected by a vertical web 26, the width of which increases in the direction of the first section 201. The two upper guide tracks 23 are provided above the T-slots 25 on the two side surfaces of the second section 202.
Für eine Gewichtsreduzierung weist das Profilelement 20 in dem Steg 26 eine Kammer 27 auf. Weiter sind an einer ungenutzten Unterseite des ersten Abschnitts des Profilelements 20 sich in Längsrichtung erstreckende Nuten 28 vorgesehen. Die Lage und/oder Form der Kammer 27 und/oder der Nuten 28 ist dabei durch den Fachmann geeignet wählbar, um eine Gewichtsreduzierung ohne relevante Schwächung des Profilelements 20 zu erzielen. For weight reduction, the profile element 20 in the web 26 has a chamber 27. Further, longitudinally extending grooves 28 are provided on an unused underside of the first portion of the profile element 20. The position and / or shape of the chamber 27 and / or the grooves 28 is suitably selectable by the skilled person to achieve a weight reduction without relevant weakening of the profile element 20.
An einer Oberseite und einer Unterseite des Profilelements 20 sind Nuten 29 vorgesehen, in welche Verbindungselemente zur Verbindung aneinander angrenzender Profilelemente 20 einsetzbar sind Grooves 29 are provided on an upper side and a lower side of the profiled element 20, into which connecting elements for connecting adjoining profile elements 20 can be inserted

Jedes Seitenteil umfasst vorzugsweise weiter zwei Führungselemente, welche mit den Führungsbahnen 23, 24 der Laufschiene 2 zusammenwirken. Insbesondere bei Fahrzeugen mit mehreren Achsmodulen sind jedoch auch Ausgestaltungen denkbar, in welchen nicht alle Seitenteile 310, 320 Führungselemente aufweisen. As described above, each side part 310, 320 (see Figures 1 and 2) comprises a running element, wherein the rail vehicle 3 is supported by means of the running elements on the raceways 33 of the running rail 2. Each side part preferably further comprises two guide elements which cooperate with the guide tracks 23, 24 of the track rail 2. However, in particular in the case of vehicles with a plurality of axle modules, embodiments are also conceivable in which not all the side parts 310, 320 have guide elements.
Die Laufelemente und Führungselemente sind vorzugsweise als Räder gestaltet. The running elements and guide elements are preferably designed as wheels.

Die Führungsräder 34, 35 sind jeweils um vertikale Achsen 340, 350 drehbar gelagert und rollen passiv entlang der Führungsbahnen 23, 24 ab. Wie in Fig. 5 erkennbar ist, sind in dem dargestellten Ausführungsbeispiel die Führungsräder 34, 35 jeweils paarweise vorgesehen. Die zwei einer Führungsbahn 23, 24 zugeordneten Führungsräder 34, 35 bilden dabei jeweils eine Führungsrädervorrichtung 341 , 351 mit zwei in Längsrichtung des Achsmoduls 31 , 32 versetzt angeordneten, um vertikale Achsen drehbar gelagerten Führungsrädern 34, 35. Wie bereits oben erwähnt, ist vorzugsweise eine Antriebsvorrichtung an dem Schienenfahrzeug vorgesehen, mittels welcher zumindest ein Laufrad 33 des Schienenfahrzeugs 3 antreibbar ist. In vorteilhaften Ausgestaltungen ist jedes Laufrad 33 des Schienenfahrzeugs 3 mittels der Antriebsvorrichtung für ein selbsttätiges Verfahren des Schienenfahrzeugs 3 entlang der Laufbahnen antreibbar. The guide wheels 34, 35 are rotatably mounted respectively about vertical axes 340, 350 and passively roll along the guideways 23, 24. As can be seen in Fig. 5, the guide wheels 34, 35 are provided in pairs in the illustrated embodiment. The two guide rails 34, 35 assigned to a guide track 23, 24 each form a guide wheel device 341, 351 with two guide wheels 34, 35, which are offset in the longitudinal direction of the axle module 31, 32 and are rotatably mounted about vertical axes. As already mentioned above, a drive device is preferably provided on the rail vehicle, by means of which at least one impeller 33 of the rail vehicle 3 can be driven.

As shown in FIGS. 1 and 2, in the exemplary embodiment, each emergency brake system 6 is assigned a mechanical switch 60, by means of which the emergency brake system can be activated.
In dem dargestellten Ausführungsbeispiel ist das Notbremssystem 6 mit der zentralen Steuereinheit 7 kommuniziert. Dadurch können Informationen der Notbremssysteme 6 an der Steuereinheit 7 verarbeitet werden. Beispielsweise ist es denkbar, dass es nur an einem Achsmodul 31 , 32 zu einer Unterbrechung der Energiezufuhr kommt, wobei diese Information an das zweite Achsmodul 32, 31 zur Einleitung entsprechender Maßnahmen weitergeleitet wird. In the illustrated embodiment, the emergency brake system 6 is communicated with the central control unit 7. As a result, information of the emergency braking systems 6 can be processed at the control unit 7. For example, it is conceivable that there is an interruption of the power supply only at one axle module 31, 32, this information being forwarded to the second axle module 32, 31 for initiating appropriate measures.
Eine Deaktivierung des Notbremssystems 6 ist in einer Ausgestaltung ausschließlich manuell mittels eines manuell betätigbaren Schaltelements 61 möglich. Das Schaltelement 61 ist in einer Ausgestaltung an einer durch eine Serviceperson zugängliche Stelle vorgesehen, beispielsweise an der Steuereinheit 7 oder an einer anderen Stelle, welche mit der Steuereinheit 7 datentechnisch verbunden ist. Die Deaktivierung erfolgt dabei in einer Ausgestaltung direkt. In vorteilhaften Ausgestaltungen erfolgt die Deaktivierung indirekt über die zentrale Steuereinheit 7. In wieder anderen Ausgestaltungen ist die zentrale Steuereinheit 7 derart gestaltet, dass sie in bestimmten Situationen eine Deaktivierung elektronisch bewirken kann, ohne manuelle Eingriffe einer Serviceperson. Deactivation of the emergency brake system 6 is possible in one embodiment exclusively manually by means of a manually operable switching element 61. In one embodiment, the switching element 61 is provided at a location accessible by a service person, for example at the control unit 7 or at another location, which is connected to the control unit 7 in terms of data technology.
