Darstellung der ErfindungPresentation of the invention
Aufgabe der Erfindung ist es, ein Schienenfahrzeug der eingangs genannten Art derart weiterzubilden, dass bei guter Übertragungsleistung der Übertragungs-Einrichtung die Geräuschentwicklung und der Verschleiss vermindert werden.The object of the invention is to develop a rail vehicle of the type mentioned at the outset in such a way that, with good transmission performance of the transmission device, noise and wear are reduced.
Die Aufgabe wird erfindungsgemäss gelöst durch die kennzeichnenden Merkmale des Anspruches 1. Dadurch, dass das Kontaktelement als Kontaktrolle im wesentlichen aus Kohlenstoff- und/oder Graphitmaterial ausgebildet ist, welche auf der Leiterschiene abrollt, werden die Geräuschentwicklung und der Verschleiss wesentlich vermindert, dies insbesondere auch beim Überfahren von Weichen, Kreuzungen, Schienentrennern und dergleichen. Dadurch ist nicht nur eine längere Standzeit der Kontaktrollen möglich sondern auch die Verschmutzung des Schienensystems, der Schienenfah zeuge und der Umwelt wird wesentlich vermindert, so dass auch ein Befahren von Reinsträumen zum Beispiel in Krankenhäusern möglich ist, ohne dass die Gefahr einer Kontamination erwächst. Dennoch werden gleichermassen eine gute Datenübertragung mit Stromstärken im mA Bereich, eine Dauerbelastung im Bereich bis zu 20 bis 30 A sowie Kurzschlussströme für Antriebsmotoren im Bereich von 100 A oder mehr ermöglicht, ohne dass die Kontakte Schaden nehmen.The object is achieved according to the invention by the characterizing features of claim 1. Because the contact element is formed as a contact roller essentially from carbon and / or graphite material which rolls on the conductor rail, the noise and wear are significantly reduced, in particular also when driving over switches, crossings, rail separators and the like. This not only enables the contact rollers to have a longer service life, it also significantly reduces the pollution of the rail system, the rail vehicles and the environment, so that it is also possible to drive into clean rooms, for example in hospitals, without increasing the risk of contamination. Nevertheless, good data transmission with currents in the mA range, a permanent load in the range up to 20 to 30 A and short-circuit currents for drive motors in the range of 100 A or more are made possible without the contacts being damaged.
Vorteilhafte Ausgestaltungen des Schienenfahrzeuges sind in den Ansprüchen 2 bis 7 beschrieben.
Grundsätzlich können für die Kontaktrolle Achsen aus verschiedenen Werkstoffen zum Einsatz kommen, besonders vorteilhaft ist jedoch eine versilberte Achse ge ass Anspruch 2.Advantageous embodiments of the rail vehicle are described in claims 2 to 7. Basically, axes made of different materials can be used for the contact roller, but a silver-plated axis is particularly advantageous.
Die Kontakteigenschaften lassen sich durch eine schwimmende Lagerung und damit durch eine höhere Anpassungsfähigkeit der Kontaktrolle der Leiterschiene und dem Schienenfahrzeug nach Anspruch 3 und/oder durch Vorspannung der Kontaktrolle gegen die Leiterschiene nach Anspruch 4 verbessern. Besonders vorteilhaft ist auch eine Weiterbildung nach Anspruch 5, wobei die Kontaktrolle in einem Lagerbock gelagert ist, der seinerseits in einer Halterung des Schienenfahrzeuges vorzugsweise schwimmend gelagert ist. Für eine zweckmässige Vorspannung des Lagerbocks und damit der Kontaktrolle gegen die Leiterschiene sorgt eine Ausbildung nach Anspruch 6.The contact properties can be improved by a floating bearing and thus by a higher adaptability of the contact roller of the conductor rail and the rail vehicle according to claim 3 and / or by pretensioning the contact roller against the conductor rail according to claim 4. A further development according to claim 5 is also particularly advantageous, the contact roller being mounted in a bearing block, which in turn is preferably mounted in a floating manner in a holder of the rail vehicle. A design according to claim 6 ensures appropriate preloading of the bearing block and thus of the contact roller against the conductor rail.
Die Übertragungsleistung der Übertragungs-Einrichtung lässt sich verbessern, wenn ge ass Anspruch 7 mindestens zwei Kontaktrollen in Fahrtrichtung hintereinander geschaltet sind.The transmission performance of the transmission device can be improved if at least two contact rollers are connected in series in the direction of travel.

In den Figuren, in denen gleiche Elemente mit gleichen Bezugszeichen versehen sind, ist die Übertragungs-Einrichtung eines Schienenfahrzeuges dargestellt, die mit einer Leiterschiene 10 zusammenwirkt, um von dieser Betriebsstrom und/oder Steuersignale auf ein selbstfahrendes Schienenfahrzeug zu übertragen. Ein solches Schienenfahrzeug ist vorzugsweise Teil einer Kleinförderanlage beispielsweise gemass der US-A 3 636 883 und dazu bestimmt, Kleinlasten wie Akten, medizinische Güter, Bauteile oder ähnliches zu transportieren.In the figures, in which the same elements are provided with the same reference numerals, the transmission device of a rail vehicle is shown which interacts with a conductor rail 10 in order to transmit operating current and / or control signals from the latter to a self-propelled rail vehicle. Such a rail vehicle is preferably part of a small conveyor system, for example in accordance with US Pat. No. 3,636,883, and is intended to transport small loads such as files, medical goods, components or the like.
Um den Betriebsstrom und/oder die Steuersignale an einen elektrischen Antriebsmotor 12 und/oder andere Bauteile und/oder Steuereinheiten des Schienenfahrzeuges zu übertragen, sind erfindungsgemäss im wesentlichen aus Kohlenstoff- und/oder Graphitmaterial bestehende Kontaktrollen 14,16 vorhanden, die beispielsweise bei einer Betriebsspannung von 24 Volt problemlos sowohl kleine Ströme wie zum Beispiel Steuerströme im Bereich von 5 mA als auch Ströme in der Grössenord- nung bis zu 30 A in Dauerbelastung oder Kurzschlussströme in der Grössenordnung von 100 A für Antriebsmotoren übertragen, ohne dass die Gefahr einer Beschädigung beziehungsweise Zerstörung der Kontakte erwächst.In order to transmit the operating current and / or the control signals to an electric drive motor 12 and / or other components and / or control units of the rail vehicle, contact rollers 14, 16 consisting essentially of carbon and / or graphite material are present according to the invention, for example at an operating voltage of 24 volts can easily transmit both small currents such as control currents in the range of 5 mA and currents in the order of magnitude up to 30 A in continuous load or short-circuit currents in the order of 100 A for drive motors without the risk of damage or destruction of contacts grows.
Im Ausführungsbeispiel sind zwei Kontaktrollen 14,16 in Fahrtrichtung hintereinander vorgesehen, um die Ströme zu übertragen. Es besteht auch die Möglichkeit, nur eine Kontaktrolle oder mehr als zwei Kontaktrollen zu verwenden beziehungsweise diese zum Beispiel paarweise nebeneinander anzuordnen.In the exemplary embodiment, two contact rollers 14, 16 are provided one behind the other in the direction of travel in order to transmit the currents. It is also possible to use only one contact roller or more than two contact rollers or to arrange them side by side, for example in pairs.
Die Kontaktrollen 14,16 sind von einem Lagerbock 18 getragen, der seinerseits in einer Halterung 20 angeordnet ist, die mit dem Schienenfahrzeug eine Einheit bildet. Der Lagerbock 18 weist im Querschnitt eine U-Form auf und hat im Ausführungsbeispiel Seitenschenkel mit einer trapezförmigen Geometrie. Vom Kopfteil 22 des Lagerbocks 18 geht ein Kontaktstift 24
aus, über den eine elektrisch leitende Verbindung zum Antriebsmotor 12 beziehungsweise nicht näher dargestellten Steuereinheiten erfolgt. Der Lagerbock 18 und damit die Kontaktrollen 14,16 sind gegenüber der Halterung 20 elektrisch isoliert.The contact rollers 14, 16 are carried by a bearing block 18, which in turn is arranged in a holder 20, which forms a unit with the rail vehicle. The bearing block 18 has a U-shape in cross section and, in the exemplary embodiment, has side legs with a trapezoidal geometry. A contact pin 24 goes from the head part 22 of the bearing block 18 from which an electrically conductive connection to the drive motor 12 or control units, not shown, takes place. The bearing block 18 and thus the contact rollers 14, 16 are electrically insulated from the holder 20.
Um einen gleichbleibenden Andruck der Kontaktrollen 14,16 auf die Leiterschiene 10 sicherzustellen, wirkt auf den Lagerbock 18 ein Federelement 26 in Form einer Spiralbandfeder, die in der Halterung 20 gelagert ist. Ein freier S-förmig gebogener Endabschnitt 28 der Spiralbandfeder 26 wirkt sodann auf den Kopfteil 22 des Lagerbocks 18, so dass auf diese Weise die erforderliche Vorspannung des Lagerbocks 18 und damit der Kontaktrollen 14,16 in Richtung der Leiterschiene 10 gewährleistet ist.In order to ensure a constant pressure of the contact rollers 14, 16 on the conductor rail 10, a spring element 26 in the form of a spiral band spring acts on the bearing block 18 and is mounted in the holder 20. A free S-shaped bent end section 28 of the spiral band spring 26 then acts on the head part 22 of the bearing block 18, so that in this way the required pretensioning of the bearing block 18 and thus the contact rollers 14, 16 in the direction of the conductor rail 10 is ensured.
Das Federelement 26, das im Ausführungsbeispiel von der Halterung 20 ausgeht, ist gegenüber dem Lagerbock 18 isoliert. Hierzu kann zumindest der mit dem Lagerbock 18 zusammenwirkende Endabschnitt 28 von einem elektrisch isolierenden Material ummantelt sein.The spring element 26, which starts from the holder 20 in the exemplary embodiment, is insulated from the bearing block 18. For this purpose, at least the end section 28 cooperating with the bearing block 18 can be encased by an electrically insulating material.
Die schwimmende Lagerung des Lagerbocks 18 kann dadurch erfolgen, dass entweder die vorzugsweise versilberten Achsen 30,32 der Kontaktrollen 14,16 ge ass Figur 1 in senkrecht zur Leiterschiene 10 verlaufenden Langlöchern 34,36 der Halterung 20 verstellbar sind oder aber der Lagerbock 18 gemass Figur 2 selbst über eine Achse 38 in entsprechenden Langlöchern 40 der Halterung 20 gelagert ist. Dabei muss sichergestellt sein, dass die Kontaktrollen 14,16 beziehungsweise deren Achsen 30,32 beziehungsweise die den Lagerbock 18 durchsetzende Achse 38 gegenüber der Halterung 20 oder die Halterung 20 selbst gegenüber den übrigen Teilen des Schienenfahrzeuges elektrisch isoliert ist. Gleiches gilt in Bezug auf den Lagerbock 18 selbst.
BezugszexchenaufStellungThe floating mounting of the bearing block 18 can take place in that either the preferably silver-plated axes 30, 32 of the contact rollers 14, 16 ge ass FIG. 1 are adjustable in elongated holes 34, 36 of the holder 20 running perpendicular to the conductor rail 10, or else the bearing block 18 according to the figure 2 itself is mounted via an axis 38 in corresponding elongated holes 40 of the holder 20. It must be ensured that the contact rollers 14, 16 or their axes 30, 32 or the axis 38 passing through the bearing block 18 are electrically insulated from the holder 20 or the holder 20 itself from the other parts of the rail vehicle. The same applies to the bearing block 18 itself. Reference character line-up
