Die Erfindung betrifft ein Laufwerk für Seilhängebahnen mit zwei Laufrollen, deren Drehachsen in Gabeln gelagert sind, die eine wagerechte Verdrehung gestatten.
Die Seilbahnlaufwerke der üblichen Bauart mit starr gelagerten Rollen zeigen den Ubelstand, daß man Kurven in einwandfreier Weise nicht durchfahren kann. Zwar sucht man sich in der Weise zu helfen, daß manThe invention relates to a running gear for overhead cable tracks with two rollers, the axes of rotation of which are mounted in forks which allow horizontal rotation.
The cable car drives of the usual design with rigidly mounted rollers show the disadvantage that you can not drive through curves in a proper manner. It is true that one tries to help oneself in such a way that one

ίο den Rollen eine Auskehlung von viel größerem Radius als sonst nötig gibt, was aber in anderer Hinsicht nachteilig ist, u. a. weil die Wagen dadurch keine sichere und exakte Führung auf dem Tragseil bzw. der Hangachse erhalten. Man hat daher auch vorgeschlagen, die Laufrollen drehbar in der wagerechten Ebene anzuordnen, so daß sie sich den Kurven selbsttätig anpassen können. Durch die vorgeschlagene Beweglichkeit der Rollen können sich aber Nachteile sowohl rein baulicher als auch betriebsmäßiger Art einstellen.ίο the roles a groove of much larger Radius than is otherwise necessary, but this is disadvantageous in other respects, i.a. because As a result, the trolleys are not guided safely and precisely on the support cable or the slope axis obtain. It has therefore also been proposed to arrange the rollers rotatably in the horizontal plane so that they can adapt to the curves automatically. The proposed mobility of the However, roles can have disadvantages of a purely structural as well as operational nature to adjust.

Die Erfindung bezieht sich nun auf eine neue Bauart von Laufwerken, deren Laufrollen wagerecht drehbar sind und bei der die Forderungen an Betriebssicherheit und Einfachheit der Bauart hinreichend berücksichtigt wurden.The invention now relates to a new type of drives, their rollers are horizontally rotatable and in which the requirements for operational safety and Simplicity of design have been sufficiently taken into account.

Man hat schon vorgeschlagen, den Rahmen des Laufwerkes aus zwei mittels eines senkrechten Gelenkes miteinander verbundenen Teilen auszuführen, um die erwähnte Beweglichkeit zu erreichen, oder man hat vorgeschlagen, die Rollen in gabelförmigen Lagern anzuordnen, die sich um senkrechte Bolzen im Rahmen des Laufwerkes drehen können. Die Erfindung baut sich auf dem zuletzt erwähnten Vorschlag auf und sucht durch zweckmäßige Maßnahme zu verhüten, daß durch die Einschaltung solcher gabelförmigen Lager das Laufwerk an Standfestigkeit einbüßt und die Drehzapfen bei geringer Bauhöhe des Laufwerkes ungehörig beansprucht werden.It has already been proposed to frame the drive from two by means of a vertical one Execute joint interconnected parts in order to achieve the aforementioned mobility to achieve, or it has been proposed to arrange the rollers in fork-shaped bearings that are around vertical bolts can rotate within the frame of the drive. The invention is based on the last-mentioned proposal and searches Appropriate measure to prevent that by including such fork-shaped Bearing the drive loses its stability and the pivot pin with a low overall height of the drive are unduly stressed.

Demgemäß besteht das Wesen der Erfindung darin, daß die Gabeln, in denen die Drehachsen gelagert sind, in Höhe der Drehachsen durch eine konvexe Abdrehung in einer entsprechenden Führung im Rahmen des Laufwerkes seitlich gestützt werden.Accordingly, the essence of the invention is that the forks in which the Axles of rotation are mounted, at the level of the axes of rotation by a convex twist in be supported laterally by a corresponding guide in the frame of the drive.

Eine Ausführungsform des Erfindungsgegenstandes ist in der Zeichnung dargestellt. Die Fig. i, 2 und 3 stellen Seitenansicht, Grundriß und Querschnitt eines Laufwerkes dar. In Fig. ι und 2 sind einige Teile geschnitten und weggebrochen.An embodiment of the subject matter of the invention is shown in the drawing. the Figures i, 2 and 3 illustrate side, plan and cross-sectional views of a drive. In Fig. Ι and 2 some parts are cut and broken away.

Die Laufrollen A sind durch Laufwerksbolzen 5 in je einer senkrecht stehenden Stahlgußgabel C gelagert. Diese Gabel hat außen auf beiden Seiten kreisförmig konvex abgedrehte Flächen D und oben einen durchbohrten Drehzapfen E. An die Traverse K, die in bekannter Weise aus einem die beiden Rollen ganz umschließenden Stahlband besteht, ist ' über jedem Rad ein Stahlgußbügel F angesetzt. Dieser Bügel ist innen mit konkav abgedrehten zylindrischen Flächen G versehen, die den konvexen Zylinderflächen D The rollers A are mounted in a vertical cast steel fork C by drive bolts 5. This fork has circular convex turned surfaces D on both sides and a pierced pivot E. On the cross member K, which consists in a known manner of a steel band completely surrounding the two rollers, a cast steel bracket F is attached above each wheel. This bracket is provided on the inside with concave turned cylindrical surfaces G , which the convex cylindrical surfaces D

Claims

correspond to fork C. At the top of the bracket J7 has a bore into which the pivot pin E fits exactly. The pivot takes up all the wheel pressure at its head end. The head end is therefore rounded and presses against a bronze plate H placed in the bore. The lateral cylindrical sliding surfaces are only exposed to the horizontally acting thrust forces and form a very firm and secure guide, whereby bending stresses in the pivot are completely avoided. An easy and safe adjustment of the running wheels, according to the existing trajectories, is thus ensured. The small hanging bolt I passing through the longitudinal axis of the pivot pin is only used to hold the fork with the associated impeller in place when the drive is lifted off the rail or the rope. In spite of the rather large wheelbase chosen, the drive shown allows smooth and easy driving through curves with a radius of only 1.50 m. The advantage of the drive is not only that it makes it easy to drive through tight curves, but also, and perhaps especially in the fact that a groove shape can be selected that has only two lines of contact on both thin and thick ropes, even after wear having. This protects the suspension ropes to a high degree and ensures that the trolley is guided safely and in a straight line, even if the hanger is tilted and the pulling force acts from the side. In the case of drives with rotatable rollers, there is also no need to reduce the wheelbase to a small amount, rather one has a certain freedom in the choice of the same. By choosing the wheelbase a little more, you can drive even more safely and protect the suspension ropes even more. A look at the wheel position, as required by a 1.50 m curve (indicated by dotted lines in the drawing), reveals that it is not easy to expect fixed castors to negotiate curves. In some cases it would also be advisable to insert a leather or rubber washer above the bronze plate against which the pivot pin presses, which significantly dampens any shocks that occur. Godfather nt-A ν Proverbs:

1. Drive for overhead cable railways with two rollers, whose axes of rotation are in forks are mounted which allow horizontal rotation, characterized in that that the forks at the level of the axes of rotation by a convex twist in a corresponding guide be supported laterally in the frame of the drive.

2. Drive according to claim 1, characterized in that the drive frame consists of a steel band (K) which completely encloses the two rollers in a known manner, in which two brackets (F) are riveted on the inside, which above the pivot (E) of the fork take up a corresponding hole and serve as a guide for the convex twisting of the fork below.
