Abstract

At each station of the overhead cable transport installation the vehicles which have been released or unclamped from the conveying cable are decelerated or accelerated by pneumatic wheels. Between the V-belt drive and the hub of each pneumatic wheel there is arranged a free-wheeling clutch or slip coupling equipped with a pre-biased restoring or return spring. The free-wheeling clutch transmits in one direction the torque or rotational moment from the V-belt drive to the pneumatic wheel without play. In the opposite direction such free-wheeling clutch rotates against the restoring moment of the pre-biased restoring spring. As a result there is eliminated the slip and the resultant wear of the pneumatic wheels upon the friction plate with which they come into contact during such time in which two neighboring pneumatic wheels engage with the friction plate.

Description

Die Erfindung geht aus von einer Seilförderanlage, insbesondere einer Seilschwebebahn nach dem Oberbegriff von Patentanspruch I.The invention is based on a cable conveyor system, in particular a cable railway according to the preamble of claim I.

Eine Sesselbahn oder Kabinenschwebebahn dieser Art ist in der US-A 4 563 955 beschrieben.A chairlift or cable car of this type is described in US-A 4,563,955.

Die Bedingung, wonach die Länge der Reibungsplatte länger sein muss, als der Abstand zwischen zwei z.B. als Pneuräder ausgestalteten Reibrädern ergibt sich aus der Forderung, dass ein Fahrzeug sowohl bei seiner Beschleunigung wie auch seiner Verzögerung immer durch mindestens ein Reibrad beherrscht und mithin ein zuverlässiger Eingriff zwischen dessen Reibungsplatte und diesem Reibrad vorhanden sein muss.The condition that the length of the friction plate must be longer than the distance between two e.g. Friction wheels designed as tire wheels result from the requirement that a vehicle, both in terms of its acceleration and deceleration, must always be controlled by at least one friction wheel, and consequently there must be reliable engagement between its friction plate and this friction wheel.

Aus der Tatsache, dass bei einer Seilbahnanlage dieser Art zwei benachbarte Reibräder auf der Beschieünigungsstrecke oder Verzögerungsstrecke zwangsweise voneinander abweichende Umfangsgeschwindigkeiten haben müssen, ergibt aber durch den sich wiederholenden gleichzeitigen Eingriff zweier Reibräder mit einer Reibungsplatte eine starke Abnützung und die unfreiwillig geleistete Reibungsarbeit ist auch mit einem entsprechenden Energieaufwand zu bezahlen.From the fact that in a cable car system of this type two adjacent friction wheels on the acceleration or deceleration section must necessarily have different peripheral speeds, the repeated simultaneous engagement of two friction wheels with a friction plate results in severe wear and tear and the involuntary friction work is also possible with one to pay corresponding energy expenditure.

Aus der FR-A 2 340 848 ist zwar eine diese Nachteile vermeidende Seilförderanlage bekannt. Dabei weisen alle Reibräder eines Satzes jeweils die gleiche Geschwindigkeit auf und diese Geschwindigkeit wird durch einen von einer Steuerung beherrschten, variablen Antrieb zur Beschleunigung der Fahrzeuge erhöht bzw. zur Verzögerung derselben gesenkt. Diese Anlage ist allerdings aufwendig und da auch Fühler benötigt werden, die von den Fahrzeugen ausgelöst werden müssen, störungsanfällig.From FR-A 2 340 848 a cable conveyor system avoiding these disadvantages is known. All of the friction wheels in a set each have the same speed, and this speed is increased by a control controlled variable drive for accelerating the vehicles or decreasing them for decelerating them. However, this system is complex and, since sensors that must be triggered by the vehicles are also prone to failure.

Aufgabe der Erfindung ist es, unter Wahrung der Einfachheit des Antriebes der Reibräder den Reibungsabrieb und die entsprechende Reibungsarbeit zu vermindern.The object of the invention is to reduce the friction abrasion and the corresponding friction work while maintaining the simplicity of the drive of the friction wheels.

Die Lösung dieser Aufgabe gelingt mit den Merkmalen des Kennzeichens von Anspruch 1.This object is achieved with the features of the characterizing part of claim 1.

Mit freiläufen ausgestattete Reibräder sind an sich aus der ebenfalls eine Seilföderanlage betreffenden EP-A 0 114 129 bekannt. In den Stationen dieser Seilföderanlage folgt anschliessend an einen mit Reibrädern besetzten Verzögerungsabschnitt ein Taktgeberabschnitt. Entlang diesem Taktgeberabschnitt sind einerseits mit einer ersten Geschwindigkeit angetriebene weitere Reibräder verteilt und andererseits erstreckt sich hier eine mit Mitnehmern besetzte Taktkette, die mit einer zweiten, gegenüber der ersten höheren Geschwindigkeit angetrieben ist. Dank der Freiläufe dieser weiteren Reibräder können die Mitnehmer beim Auftreffen auf die Fahrzeuge innerhalb des Taktgeberabschnittes diese unter Beschleunigung auf die Geschwindigkeit der Kette im vorgegebenen Taktabstand mitnehmen.Friction wheels equipped with freewheels are known per se from EP-A 0 114 129, which also relates to a cable conveyor system. In the stations of this cable conveyor system, a timing section follows a delay section with friction wheels. Along this clock generator section, on the one hand, further friction wheels driven at a first speed are distributed and, on the other hand, a clock chain occupied by drivers extends here, which is driven at a second speed that is higher than the first. Thanks to the freewheels of these additional friction wheels, the drivers can hit the vehicles within the timing section when they hit the vehicle, accelerating to the speed of the chain at the specified cycle interval.

Kommen bei der erfindungsgemässen Lösung an einer Reibungsplatte jeweils zwei Pneuräder unterschiedlicher Umfangsgeschwindigkeit gleichzeitig zum Eingriff, so bestimmt jeweils das in Bewegungsrichtung des Fahrzeuges nachfolgende Reibrad die Geschwindigkeit desselben, während das in Bewegungsrichtung vorangehende Reibrad dank der Freilaufkupplung kurzzeitig die gleiche Geschwindigkeit annehmen kann. Da die durch die Freilaufkupplung ermöglichte Verdrehung zwischen Reibrad und Antriebsglied umfangmässig begrenzt ist, kann auch in der umgekehrten Drehrichtung nach Durchlaufen des Freilaufbereiches ein Drehmoment zwischen Reibrad und Antriebsglied übertragen werden.If, in the solution according to the invention, two tire wheels of different circumferential speeds come into engagement at the same time on a friction plate, the friction wheel following in the direction of movement of the vehicle determines the speed thereof, while the friction wheel preceding in the direction of movement can temporarily take on the same speed thanks to the one-way clutch. Since the rotation between the friction wheel and the drive member, which is made possible by the one-way clutch, is limited in scope, a torque can also be transmitted between the friction wheel and the drive member in the reverse direction of rotation after passing through the free-wheel area.

Erfindungsgemäss kann die Freilaufkupplung dadurch kostengünstig ausgestaltet werden, dass sie Mitnehmer aufweist, die mit Umfangsspiel in das Reibrad eingreifen, wobei z.B. Federmitter vorgesehen sind, um die Mitnehmer relativ zum Reibrad in einer Normallage zu halten, bzw. in diese nach einer Verdichtung zurückzuführen.According to the invention, the one-way clutch can be designed cost-effectively by having drivers which engage in the friction wheel with circumferential play, e.g. Spring centers are provided to keep the drivers in a normal position relative to the friction wheel, or to return them to them after compression.

Der Erfindungsgegenstand wird nachstehend anhand der Zeichnung beispielsweise näher erläutert.The subject matter of the invention is explained in more detail below with reference to the drawing, for example.

In den Figuren ist als Seilförderanlage eine Seilschwebebahn dargestellt. Die Seilförderanlage kann aber auch zum Beispiel in Giessereien, bei Palettenförderung usw. eingesetzt werden.In the figures, a cable railway is shown as a cable conveyor. The cable conveyor system can also be used, for example, in foundries, for pallet conveying, etc.

In Fig. I ist mit I ein Förderseil der Seilschwebebahn bezeichnet, das in Betrieb dauernd umläuft und eine mit A bezeichnete Talstation mit einer nicht dargestellten Bergstation verbindet. Die Seilschwebebahn umfasst weiter eine Vielzahl von Fahrzeugen, von denen eines bei 2 dargestellt ist, wobei die Fahrzeuge für den Transport zwischen den Stationen mit dem Förderseil I gekuppelt und an diesem aufgehängt sind.In Fig. I, I is a conveyor cable of the cable railway, which circulates continuously in operation and connects a valley station labeled A with a mountain station, not shown. The cable railway also comprises a large number of vehicles, one of which is shown at 2, the vehicles being coupled to the conveyor cable I for transport between the stations and being suspended on the latter.

In den Stationen sind die Fahrzeuge 2 mittels Fahrwerken 7 derselben an einer Ueberführungsschiene 4 abgestützt, welche von einem Einlaufbereich B über einen 180° Bogenteil C zu einem Auslaufbereich D führt. Dem Einlaufbereich B und dem Auslaufbereich D sind Pneuradsätze 5a bzw. 5b zugeordnet, die eine Vielzahl von in Bewegungsrichtung hintereinander angeordneten Pneurädern aufweisen.In the stations, the vehicles 2 are supported by a chassis 7 on a transfer rail 4, which leads from an inlet area B via a 180 ° curved part C to an outlet area D. Tire wheel sets 5a and 5b are assigned to inlet area B and outlet area D, which have a plurality of tire wheels arranged one behind the other in the direction of movement.

Wie sich aus den Fig. I und 3 ergibt, weist das Fahrwerk 7 jedes Fahrzeuges 2 neben Fahrrollen 7a, die sich auf der Ueberführungsschiene 4 abstützen, zwei hintereinander angeordnete Klemmen 3 auf, die die Kupplung mit dem Förderseil I ermöglichen. Jedes Fahrwerk 7 ist schliesslich mit einer in dessen Längsrichtung verlaufenden und mit diesem starr verbundenen Reibungsplatte 8 ausgestattet, die sich parallel zur Ueberführungsschiene erstreckt. Die Länge der Reibungsplatte 8 ist etwas grösser als der Abstand zwischen zwei benachbarten Pneurädern 5a bzw. 5b, so dass die Reibungsplatte im Bereich der Radsätze stets mit einem der Pneuräder im Eingriff steht. Im Einlaufbereich B haben die Pneuräder 5a die Aufgabe, durch Eingriff mit der Reibungsplatte das mit Seilgeschwindigkeit ankommende Fahrzeug abzubremsen, während die Pneuräder 5b im Auslaufsbereich D das Fahrzeug auf die Seilgeschwindigkeit beschleunigen. Hierzu sind die einzelnen Pneuräder 5a bzw. 5b jedes Satzes mit voneinander abweichenden Drehzahlen in nachfolgend noch näherbeschriebener Weise angetrieben. Jedenfalls weisen im Einlaufbereich B der Station sich in Bewegungsrichtung der Fahrzeuge folgende Pneuräder abnehmende Drehzahlen auf, während im Auslaufsbereich D sich in Richtung auf das Seil folgende Pneuräder zunehmende Drehzahlen aufweisen.As can be seen from FIGS. I and 3, the undercarriage 7 of each vehicle 2, in addition to castors 7a, which are supported on the transfer rail 4, has two clamps 3 arranged one behind the other, which enable the coupling with the conveyor cable I. Finally, each undercarriage 7 is in one its longitudinal direction extending and rigidly connected to this friction plate 8, which extends parallel to the transfer rail. The length of the friction plate 8 is somewhat greater than the distance between two adjacent tire wheels 5a and 5b, so that the friction plate is always in engagement with one of the tire wheels in the area of the wheel sets. In the entry area B, the tire wheels 5a have the task of braking the vehicle arriving at the rope speed by engaging the friction plate, while the tire wheels 5b in the exit area D accelerate the vehicle to the rope speed. For this purpose, the individual tire wheels 5a and 5b of each set are driven at different speeds in the manner described in more detail below. In any case, the following tire wheels have decreasing speeds in the entry area B of the station in the direction of movement of the vehicles, while in the exit area D the following tire wheels have increasing speeds in the direction of the rope.

Jedes Pneurad 5a steht mit einem Antriebsglied in Form eines Keilriemenantriebes 6 in Verbindung. Jedes Pneurad 5a umfasst eine Nabe 10 mit einer Aussparung 13, eine Felge II und einen Pneu 12. Jedes Pneurad 5a ist mittels zwei Wälzlagern 18 auf einer Achse 15 drehbar gelagert, die daneben zwei Riemenscheiben 6a und 6b ebenfalls drehbar abstützt. Alle Achsen 15 des Satzes von Pneurädern 5a sind in einer gemeinsamen Ebene parallel zueinander an einem Träger 20 befestigt, welcher seinerseits parallel zur Ueberführungsschiene 4 im Einlaufbereich B verläuft. Die unterschiedliche Durchmesser aufweisenden Riemenscheiben 6a und 6b sind untereinander durch zwei mit Muttern 9 versehene, diametral angeordnete Schrauben 16 verbunden, die mit ihren Köpfen 16a in diametral angeordnete Taschen 13a der Aussparungen 13 in der Nabe 10 eingreifen. In der Aussparung 13 bzw. einer der Taschen 13a ist weiter eine vorgespannte Rückstellfeder 14 eingesetzt. Wie sich deutlich aus den Fig. 4 und 5 ergibt, bildet die Rückstellfeder 14 zwei Schleifen 14a, 14b, von denen die kleinere Schleife 14a den Kopf 16a einer der beiden Schrauben 16 umschlingt. Die grössere Schleife 14b der Rückstellfeder 14 umschlingt mit Abstand die Achse 15 des Pneurades 5a und stützt sich mit ihrem Ende 14c bei 10a an der Nabe 10 ab.Each tire wheel 5a is connected to a drive member in the form of a V-belt drive 6. Each tire wheel 5a comprises a hub 10 with a recess 13, a rim II and a tire 12. Each tire wheel 5a is rotatably mounted on an axis 15 by means of two roller bearings 18, which also rotatably supports two pulleys 6a and 6b. All axes 15 of the set of tire wheels 5a are fastened in a common plane parallel to one another on a carrier 20 which in turn runs parallel to the transfer rail 4 in the inlet area B. The different diameter pulleys 6a and 6b are connected to one another by two diametrically arranged screws 16 provided with nuts 9, which with their heads 16a engage in diametrically arranged pockets 13a of the recesses 13 in the hub 10. A prestressed return spring 14 is also inserted in the recess 13 or one of the pockets 13a. 4 and 5, the return spring 14 forms two loops 14a, 14b, of which the smaller loop 14a wraps around the head 16a of one of the two screws 16. The larger loop 14b of the return spring 14 wraps around the axis 15 of the tire wheel 5a at a distance and is supported by the end 14c at 10a on the hub 10.

Erfindungsgemäss sind die Antriebsglieder bzw. Keilriemengetriebe 6 mit ihren Pneurädern 5a über je eine Freilaufkupplung verbunden, die durch die Taschen 13a und die Schraubenköpfe 16a gebildet ist. Wie aus den Fig. 4 und 5 ersichtlich ist, greifen als Mitnehmer wirkende Schrauben 16 mit deren Köpfe 16a mit Spiel in die Taschen 13a der Nabe 10 ein und lassen eine Verdrehung der Pneuräder 5a relativ zu den Antriebsgliedern um den Winkel a(Fig. 5) zu. Eine solche Verdrehung aus der in Fig. 5 dargestellten Normallage in Richtung der in Fig. 4 gezeigte Endlage ist allerdings nur in einer Drehrichtung und nur entgegen der Wirkung der vorgespannten Feder 14 möglich.According to the invention, the drive members or V-belt transmission 6 are connected to their tire wheels 5a via a one-way clutch, which is formed by the pockets 13a and the screw heads 16a. As can be seen from FIGS. 4 and 5, screws 16 acting as drivers engage with their heads 16a with play in the pockets 13a of the hub 10 and allow the tire wheels 5a to be rotated relative to the drive members by the angle a (FIG. 5 ) too. Such a rotation from the normal position shown in FIG. 5 in the direction of the end position shown in FIG. 4 is only possible in one direction of rotation and only against the action of the prestressed spring 14.

Die vorstehend beschriebene Anordnung für die Pneuräder 5a des Einlaufbereiches B gilt gleichfalls für die Pneuräder 5b im Auslaufbereich D der Station.The arrangement described above for the tire wheels 5a of the inlet area B also applies to the tire wheels 5b in the outlet area D of the station.

Der Antrieb der Pneuräder 5a und 5b der beiden Radsätze der Station A erfolgt von einem mit M bezeichneten Antriebsmotor aus, der auch das Förderseil I über eine von diesem umschlungene Seilscheibe la antreibt. Hierzu ist der Motor M über ein Getriebe G sowie Transmissionswellen T mit der Seilscheibe la und den Pneurädern 5a' und 5b' verbunden, wobei es sich bei diesen um das erste Pneurad 5a des Einlaufbereiches B und das letzte Pneurad des Auslaufbereiches D handelt. Durch das Getriebe G erhalten diese beiden Pneuräder 5a' und 5b' eine Umfangsgeschwindigkeit, welche der Umfangsgeschwindigkeit der Seilscheibe la und damit der Geschwindigkeit des Förderseiles I gleich ist.The tire wheels 5a and 5b of the two wheel sets of station A are driven by a drive motor denoted by M, which also drives the conveyor cable I via a cable pulley la which is wrapped around it. For this purpose, the motor M is connected via a gearbox G and transmission shafts T to the rope pulley la and the tire wheels 5a 'and 5b', these being the first tire wheel 5a of the inlet area B and the last tire wheel of the outlet area D. The gear G gives these two tire wheels 5a 'and 5b' a circumferential speed which is the same as the circumferential speed of the sheave la and thus the speed of the conveyor cable I.

Wie aus Fig. 3 weiter ersichtlich ist, umfasst jedes Keilriemengetriebe einen Keilriemen 6c, der die im Durchmesser kleinere Riemenscheibe 6a eines Pneurades 5a oder 5b mit der im Durchmesser grösseren Riemenscheibe 6b des nach links folgenden Pneurades 5a bzw. 5b verbindet. Mithin nehmen die Drehzahlen der einzelnen Pneuräder 5a und 5b mit zunehmendem Abstand von den Pneurädern 5a' bzw. 5b' ab.As can also be seen from FIG. 3, each V-belt transmission comprises a V-belt 6c, which connects the smaller pulley 6a of a tire wheel 5a or 5b with the larger pulley 6b of the left-hand tire wheel 5a or 5b. The speeds of the individual tire wheels 5a and 5b therefore decrease with increasing distance from the tire wheels 5a 'and 5b'.

Dementsprechend wird ein in die Station A einlaufendes Fahrzeug 2 durch die Einwirkung der Pneuräder 5a auf die Reibungsplatte 8 allmählich verzögert. Andererseits beschleunigen die Pneuräder 5b ein Fahrzeug 2 im Auslaufbereich D allmählich, bis dieses durch das letzte Rad die Seilgeschwindigkeit erreicht hat und anschliessend stossfrei durch das Schliessen der Klemmen 3 mit dem Seil I gekuppelt werden kann.Accordingly, a vehicle 2 entering the station A is gradually decelerated by the action of the tire wheels 5a on the friction plate 8. On the other hand, the tire wheels 5b gradually accelerate a vehicle 2 in the run-out area D until it has reached the rope speed through the last wheel and can then be coupled with the rope I without jolts by closing the clamps 3.

Anhand der Fig. 3, 4 und 5 wird nachfolgend die Wirkungsweise der Freilaufkupplung am Beispiel des Auslaufbereiches D, d.h. beim Beschleunigen eines Fahrzeuges 2 durch die an dessen Reibungsplatte 8 angreifenden Pneuräder 5b erläutert.3, 4 and 5, the mode of operation of the one-way clutch is illustrated below using the example of the outlet area D, i.e. when accelerating a vehicle 2 explained by the tire wheels 5b acting on its friction plate 8.

Aus einem Wegabschnitt des Auslaufbereiches D, auf welchem lediglich eines der Pneuräder 5b auf die Reibungsplatte 8 eines Fahrzeuges 2 einwirkt und dieses auf die dessen Umfangsgeschwindigkeit entsprechende Fahrgeschwindigkeit beschleunigt, wird das Fahrzeug in Richtung des Pfeiles 20'gefördert und gelangt dabei in die in Fig. 3 gezeigte Stellung. Dabei ist die Reibungsplatte 8 mit ihrer Reibfläche 8a mit einem in Bewegungsrichtung nachfolgenden zweiten Pneurad 5b in Eingriff gelangt, das mit einer gegenüber dem vorangehenden Pneurad mit höherer Umfangsgeschwindigkeit angetrieben ist. An diesem letzteren Pneurad weisen die Teile der Freilaufkupplung die in Fig. 5 dargestellte Normallage auf und damit wird das zweite Pneurad bei der Drehung im Gegenuhrzeigersinn des Keilriemengetriebes 6 bzw. der Schraubenköpfe 16a starr mitgenommen. Dieses Pneurad nimmt durch Reibungsschluss mit der Reibfläche 8a mit der diesem eigenen höheren Umfangsgeschwindigkeit das Fahrwerk auf der Ueberführungsschiene 4 mit. Gleichzeitig wird an dem von seinem Keilriemengetriebe 6 mit niedrigerer Umfangsgeschwindigkeit angetriebenen vorangehenden Pneurad 5b von der Reibungsplatte 8 eine Reibungskraft ausgeübt. Dank dem Freilauf kann nun das entsprechende vorangehende Pneurad sich auf die Bewegungsgeschwindigkeit der Reibungsplatte 8 beschleunigen und damit seinem Keilriemenantrieb unter Verdrehung der Teile entgegen der Wirkung der Rückstellfeder 14 in Richtung der in Fig. 4 dargestellten Endlage vorauseilen. Sobald jedoch die Reibungsplatte 8 ausser Eingriff mit diesem vorangehenden Pneurad gelangt ist, dreht die Rückstellfeder 14 dasselbe in die Lage zurück, in welchem die Teile der Kupplung die Normallage nach Fig. 5 einnehmen.The vehicle is conveyed in the direction of arrow 20 'from a path section of the run-out area D, on which only one of the tire wheels 5b acts on the friction plate 8 of a vehicle 2 and accelerates it to the travel speed corresponding to its peripheral speed, and thereby arrives in the direction shown in FIG. 3 position shown. In this case, the friction plate 8 has come into engagement with its friction surface 8a with a second tire wheel 5b following in the direction of movement, which is driven with a higher peripheral speed than the preceding tire wheel. On this latter tire wheel, the parts of the one-way clutch have the normal position shown in FIG. 5 and thus the second tire wheel is rigidly carried along when the V-belt transmission 6 or the screw heads 16a rotate counterclockwise. This tire wheel takes the running gear on the transfer rail 4 by frictional engagement with the friction surface 8a with its own higher peripheral speed. At the same time, the friction plate 8 exerts a frictional force on the preceding tire wheel 5b driven by its V-belt transmission 6 at a lower peripheral speed. Thanks to the freewheel, the corresponding can now the preceding tire wheel accelerate to the speed of movement of the friction plate 8 and thus advance its V-belt drive while rotating the parts against the action of the return spring 14 in the direction of the end position shown in FIG. 4. However, as soon as the friction plate 8 has come out of engagement with this preceding tire wheel, the return spring 14 rotates the same back into the position in which the parts of the clutch assume the normal position according to FIG. 5.

Dank der Freilaufkupplung wird somit der Reibungsverschleiss durch gleichzeitige Einwirkung von zwei mit unterschiedlicher Drehzahl angetriebenen Pneurädern auf die gleiche Reibungsplatte wesentlich vermindert, da sich der beschriebene Vorgang bei allen Pneurädern 5b der Auslaufstrecke wiederholt.Thanks to the one-way clutch, the frictional wear is considerably reduced by the simultaneous action of two tire wheels driven at different speeds on the same friction plate, since the process described is repeated for all tire wheels 5b of the outlet section.

An den Pneurädern 5a der Einlaufstrecke B haben die Freilaufkupplungen die gleiche Funktion. Wiederum ist die Freilaufkupplung so eingebaut, dass das in Bewegungsrichtung nachfolgende Rad - hier das mit niedrigerer Umfangsgeschwindigkeit angetriebene Pneurad - die Geschwindigkeit des mit der gleichen Reibungsplatte im Eingriff stehenden vorausgehenden Pneurades bestimmt. Bei der Verzögerung durch das nachfolgende Pneurad wird hier das in Bewegungsrichtung vorangehende Pneurad ebenfalls so lange verzögert, bis dieses ausser Eingriff mit der Reibungsplatte gelangt. Während dieser Zeit eilt der Keilriemenantrieb seinem Pneurad voraus.The one-way clutches have the same function on the tire wheels 5a of the inlet section B. Again, the one-way clutch is installed in such a way that the wheel following in the direction of movement - here the tire wheel driven at a lower peripheral speed - determines the speed of the preceding tire wheel which is engaged with the same friction plate. When decelerated by the following tire wheel, the previous tire wheel in the direction of movement is also decelerated until it comes out of engagement with the friction plate. During this time, the V-belt drive runs ahead of its tire.

Der Winkel a ist in Abhängigkeit von dem Mass gewählt, um welches die durch Länge und Ausgestaltung gegebene Eingriffsstrecke der Reibungsplatte 8 grösser ist als der Abstand zwischen zwei Pneurädern bzw. deren Achsen. Es hat sich gezeigt, dass ein Winkel a von etwas 100 ausreicht, um den gleichzeitigen Eingriff von zwei Pneurädern vor Erreichen der Endlage gemäss Fig. 4 zu beenden. Die Endlage nach Fig. 4 wird nur dann erreicht, wenn z.B. im Falle einer Störung die Pneuräder mit umgekehrter Drehrichtung angetrieben werden sollen, um Fahrzeuge rückwärts zu bewegen. Die Reibungsplatte 8 kann aus Kunststoff bestehen und an der Reibfläche mit Erhebungen, z.B. quer verlaufenden Rippen versehen sein.The angle a is selected as a function of the dimension by which the engagement distance of the friction plate 8 given by length and design is greater than the distance between two tire wheels or their axes. It has been shown that an angle a of approximately 100 is sufficient to end the simultaneous engagement of two tire wheels before reaching the end position according to FIG. 4. The end position according to Fig. 4 is only reached if e.g. In the event of a fault, the tire wheels should be driven in the opposite direction of rotation in order to move vehicles backwards. The friction plate 8 can be made of plastic and can be provided on the friction surface with elevations, e.g. be provided with transverse ribs.

In der Regel ist ein Teil der Pneuräder 5a am Ende der Einlaufstrecke B sowie am Anfang des Auslaufbereiches D mit unter sich gleicher Geschwindigkeit angetrieben. Dementsprechend bedarf es zwischen diesen Pneurädern und ihren Antriebsgliedern keiner Freilaufkupplung.As a rule, part of the tire wheels 5a at the end of the inlet section B and at the beginning of the outlet section D is driven at the same speed. Accordingly, no one-way clutch is required between these tire wheels and their drive members.
