Abstract

The lift proposed has two fixed parallel sectional rails along each of which rollers run, the rollers being rotatably mounted on roller carriers and making contact with different sides of the rails. At least one of the rollers on each roller carrier is designed as a drive wheel. The surface of the drive wheel is pressed against the appropriate contact surface of the rail by spring force so that the motive force exerted by the drive wheel is transmitted to the rail substantially without slipping occurring.

Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft einen Aufzug, insbesondere Schrägaufzug, mit einem ersten und einem zweiten ortsfesten Fahrbahnprofil, insbesondere Fahrbahnrohr, bei dem an beiden Fahrbahnprofilen jeweils Führungsrollen ablaufen, die auf Rollenträgern drehbar gelagert sind und von unterschiedlichen Seiten an den Fahrbahnprofilen anliegen, wobei mindestens eine Führungsrolle des dem ersten Fahrbahnprofil zugeordneten ersten Rollenträgers als Antriebsrad ausgebildet ist, und der Umfang des Antriebsrads über Federkraft derart an den zugehörigen Eingriffsbereich des ersten Fahrbahnprofils angepreßt wird, daß die Antriebskraft des Antriebsrads zumindest im wesentlichen kraftschlüssig auf das erste Fahrbahnprofil übertragen wird.The invention relates to an elevator, in particular inclined elevator, with a first and a second fixed roadway profile, in particular roadway tube, in which guide rollers run on both roadway profiles, which are rotatably mounted on roller carriers and rest on the roadway profiles from different sides, at least one guide roller of the The first roller carrier assigned to the first roadway profile is designed as a drive wheel, and the circumference of the drive wheel is pressed by spring force to the associated engagement area of the first roadway profile in such a way that the drive force of the drive wheel is transmitted at least essentially non-positively to the first roadway profile.

STAND DER TECHNIKSTATE OF THE ART

Ein bekannter Aufzug dieser Art (GB-A-778 091) ist als Stuhlanlage ausgebildet. Bei diesem bekannten Aufzug wird die gesamte Antriebskraft kraftschlüssig auf lediglich ein Fahrbahnprofil übertragen. Ein zweites Fahrbahnprofil dient lediglich als Führungsprofil, an dem Führungsrollen ablaufen, die den Sitz stets in horizontaler Lage halten sollen. Der bekannte Antrieb hat sich in der Praxis nicht durchgesetzt. Er ist auch lediglich für relativ geringe Antriebsleistungen verwendbar.A known elevator of this type (GB-A-778 091) is designed as a chair system. In this known elevator, the entire driving force is transmitted non-positively to only one lane profile. A second lane profile serves only as a guide profile on which guide rollers run, which are intended to keep the seat in a horizontal position at all times. The known drive has not become established in practice. It can only be used for relatively low drive power.

Bei anderen bekannten Aufzügen ähnlicher Art dienen die Fahrbahnprofile ausschließlich als Führungsprofile, an denen zugehörige Führungsrollen ablaufen. Der Antrieb des Aufzugs erfolgt bei diesen bekannten Konstruktionen, welche größere Antriebsleistungen zulassen, mit zusätzlichen Antriebselementen.In other known elevators of a similar type, the carriageway profiles serve exclusively as guide profiles on which associated guide rollers run. In these known constructions, which allow greater drive powers, the elevator is driven with additional drive elements.

Bei einer bekannten Ausführung ist ein Zugseil vorgesehen, das endlos in den Führungsrohren läuft und bei dem die Verbindung zwischen Zugseil und Lastaufnahmemittel über einen Schlitz im oberen Führungsrohr erfolgt.In a known embodiment, a pull rope is provided which runs endlessly in the guide tubes and in which the connection between the pull rope and the load-carrying means takes place via a slot in the upper guide tube.

Es ist ferner bekannt, den Antrieb über Zahnstangen vorzunehmen, die sich parallel zu den Fahrbahnprofilen erstrekken und auf denen ein Zahnrad abläuft.It is also known to carry out the drive via racks, which extend parallel to the roadway profiles and on which a gear runs.

Weiterhin ist es bekannt (DE-PS 29 46 780), den Antrieb durch eine am Lastaufnahmemittel gelagerte und angetriebene Schnecke vorzunehmen, die mit einem Schneckenrad zusammenwirkt, dessen Verzahnung abgewickelt und auf mehrere gleiche Segmentplatten aufgeteilt ist.Furthermore, it is known (DE-PS 29 46 780) to carry out the drive by a worm mounted and driven on the load-carrying means, which interacts with a worm wheel, the teeth of which are unwound and divided into several identical segment plates.

Diese bekannten Aufzugseinrichtungen haben sämtlich den Nachteil, daß sowohl ihre Herstellung als auch ihre Montage vergleichsweise aufwendig sind.These known elevator devices all have the disadvantage that both their manufacture and their assembly are comparatively complex.

Darüber hinaus sind auch bereits Hängeförderer bekannt, bei denen lediglich ein einziges Fahrbahnrohr vorgesehen ist, an dem eine Antriebseinrichtung abläuft, an die das Lastaufnahmemittel mit einem Bügel wie bei einem Sessellift angehängt ist (EU 0 088 061 A2). Bei dieser bekannten Vorrichtung wird die Antriebskraft des Antriebsrades im wesentlichen kraftschlüssig auf das Fahrbahnprofil übertragen. Derartige, aus Hängebahnförderern entwickelte Konstruktionen besitzen den schwerwiegenden Nachteil, daß sie keine sichere Führung für das Lastaufnahmemittel besitzen. Sie sind deshalb in den meisten Fällen als Personenaufzüge, insbesondere als Behindertenaufzüge nicht zulässig.In addition, overhead conveyors are also already known, in which only a single carriageway tube is provided, on which a drive device runs, to which the load suspension device is attached with a bracket, as in a chair lift (EU 0 088 061 A2). In this known The drive force of the drive wheel is transmitted essentially non-positively to the roadway profile. Such constructions developed from overhead conveyor conveyors have the serious disadvantage that they have no reliable guidance for the load suspension means. In most cases, they are therefore not permitted as passenger lifts, especially as handicapped lifts.

DIE ERFINDUNGTHE INVENTION

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Aufzug der als bekannt vorausgesetzten Art so auszubilden, daß er mit einfachen Mitteln preisgünstig und dennoch einwandfrei funktionsfähig herstellbar ist und auch hohe Antriebsleistungen zuläßt.Based on this prior art, the invention has for its object to design an elevator of the type presupposed as known so that it can be manufactured inexpensively and still function perfectly with simple means and also permits high drive powers.

Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Kennzeichnungsteils von Anspruch 1.This object is achieved with the features of the labeling part of claim 1.

Der erfindungsgemäße Aufzug hat den Vorteil, daß eine sichere Führung des Lastaufnahmemittels in jeder gewünschten Richtung und Richtungsänderung erfolgt. Der erfindungsgemäße Aufzug kann sowohl an geradlinigen als auch an gebogenen Fahrbahnprofilen sicher ablaufen. Die Fahrbahnprofile können sowohl waagerecht als auch senkrecht, sowohl aufsteigend als auch absteigend angeordnet sein. Darüber hinaus können die Fahrbahnprofile auch in Draufsicht gebogen sein und enge Kurven bilden, wie dies beispielsweise für den Einsatz in Treppenhäusern nötig ist.The elevator according to the invention has the advantage that the load suspension device is guided securely in any desired direction and change of direction. The elevator according to the invention can run safely on both straight and curved lane profiles. The roadway profiles can be arranged both horizontally and vertically, both ascending and descending. In addition, the roadway profiles can also be curved in a top view and form tight curves, as is necessary, for example, for use in stairwells.

Die erfindungsgemäße Konstruktion erlaubt jeden gewünschten Verfahrweg.The construction according to the invention allows any desired travel path.

Es hat sich als besonders zweckmäßig erwiesen, daß die Antriebskraft mittels einer geführten Druckfeder erzeugt wird. Das Vorsehen einer geführten Druckfeder hat zur Folge, daß auch im Falle eines Federbruchs die verbleibenden Federkräfte eine ausreichende Anpreßkraft der Antriebsräder an den Führungsprofilen beibehalten.It has proven particularly expedient that the driving force is generated by means of a guided compression spring. The provision of a guided compression spring has the result that even in the event of a spring break, the remaining spring forces maintain a sufficient contact pressure of the drive wheels on the guide profiles.

Als besonders zweckmäßig hat es sich erwiesen, daß die geführte Druckfeder zwischen den beiden um horizontale Achsen schwenkbar gelagerten Rollenträgern gespannt ist und mit Abstand von deren Schwenkachsen angreift.It has proven to be particularly expedient for the guided compression spring to be tensioned between the two roller supports pivotably mounted about horizontal axes and to engage at a distance from their pivot axes.

Weitere bevorzugte Ausgestaltungen der Erfindung sind in den weiteren Unteransprüchen beschrieben.Further preferred embodiments of the invention are described in the further subclaims.

BESTER WEG ZUR AUSFÜHRUNG DER ERFINDUNGBEST WAY TO CARRY OUT THE INVENTION

In den Zeichnungen sind gleiche oder einander entsprechende Teile mit gleichen Bezugszeichen versehen. Sie unterscheiden sich bei den unterschiedlichen Ausführungsformen lediglich durch das Vorsehen bzw. die Anzahl von Hochstrichen voneinander.In the drawings, the same or corresponding parts are provided with the same reference numerals. In the different embodiments, they differ from one another only by the provision or the number of dashes.

Zunächst zur Ausführungsform gemäß Figuren 1 bis 3:
Oberhalb einer insgesamt mit 70 bezeichneten Treppe sind seitlich zwei parallel zueinander verlaufende Fahrbahnprofile 1 und 2, die als Fahrbahnrohre ausgebildet sind, an einer Seitenwand angeordnet. Die parallel zueinander verlaufenden Fahrbahnprofile 1 und 2 besitzen ein konstantes Stichmaß, also einen konstanten, senkrecht gemessenen Abstand voneinander.First of all to the embodiment according to FIGS. 1 to 3:
Above a staircase designated as 70 in total, two parallel roadway profiles 1 and 2, which are designed as roadway tubes, are arranged on a side wall. The roadway profiles 1 and 2, which run parallel to one another, have a constant pitch, ie a constant, perpendicularly measured distance from one another.

In diesem Ausführungsbeispiel ist ein oberer Antrieb vorgesehen, der einen Motor 3 und ein Getriebe 4 aufweist.In this exemplary embodiment, an upper drive is provided, which has a motor 3 and a transmission 4.

Das Getriebe treibt ein Antriebsrad 7, das um eine Achse 14 drehbar auf einem Rollenträger 5 gelagert ist, der einen schwenkbaren Bereich eines Fahrgestells 6 bildet. Das Antriebsrad 7 ist zur Erhöhung des Reibwerts mit einer Kunststoffauflage 7a aus Polyurethan beschichtet. Das Antriebsrad 7 ist fest mit einem gleichachsig gelagerten Zahnradbereich 11 verbunden. Der Zahnradbereich 11 steht im Eingriff mit einem Zahnradbereich 12, der seinerseits mit einem Gegenrad fest verbunden und um eine Achse 15 drehbar ist. Das Antriebsrad 7 und das Gegenrad 8 ergreifen klemmend das zwischen den beiden vorgesehene Fahrbahnprofil 1. Das Fahrbahnprofil 1 besitzt einen Eingriffsbereich 1a, der aufgerauht ausgebildet ist. An diesem Eingriffsbereich 1a läuft der Umfang des Antriebsrads 7 ab. Antriebsrad 7 und Eingriffsbereich 1a stehen also in einem kraftschlüssigen Eingriff miteinander.The transmission drives a drive wheel 7, which is rotatably mounted about an axis 14 on a roller carrier 5, which forms a pivotable area of a chassis 6. The drive wheel 7 is coated with a plastic pad 7a made of polyurethane to increase the coefficient of friction. The drive wheel 7 is firmly connected to a coaxial gear area 11. The gearwheel region 11 is in engagement with a gearwheel region 12, which in turn is firmly connected to a counter wheel and is rotatable about an axis 15. The drive wheel 7 and the mating wheel 8 clamply grip the roadway profile 1 provided between the two. The roadway profile 1 has an engagement region 1a which is roughened. The circumference of the drive wheel 7 runs from this engagement region 1a. Drive wheel 7 and engagement area 1a are thus in a frictional engagement with one another.

An dem Rollenträger 5 des Fahrgestells 6 sitzen ferner zwei Führungsrollen 9 und 10, welche drehbar darauf gelagert sind.On the roller carrier 5 of the chassis 6 there are also two guide rollers 9 and 10 which are rotatably mounted thereon.

Der Abstand zwischen der Drehachse 14 und der Drehachse 15 ist dadurch veränderbar, daß die Drehachse 15 von einem exzentrisch gelagerten, nicht dargestellten Bolzen gebildet wird. Mit dem exzentrischen Bereich des Bolzens ist ein Hebelarm 16 fest verbunden. Am Ende dieses Hebelarms greift ein Federelement 17 an. Dieser Angriff erfolgt in der Weise, daß die Angriffsrichtung zu einer Verringerung des Achsabstands zwischen den Drehachsen 14 und 15 tendiert. Entsprechend der Federkraft kann auf diese Weise die Anpreßkraft zwischen dem Antriebsrad 7, dem Gegenrad 8 und dem Fahrbahnrohr 1 gewählt werden.The distance between the axis of rotation 14 and the axis of rotation 15 can be changed in that the axis of rotation 15 is formed by an eccentrically mounted bolt, not shown. A lever arm 16 is fixedly connected to the eccentric area of the bolt. At the end of this lever arm, a spring element 17 engages. This attack takes place in such a way that the direction of attack tends to reduce the center distance between the axes of rotation 14 and 15. According to the spring force, the contact pressure between the drive wheel 7, the counter wheel 8 and the track tube 1 can be selected in this way.

An dem Antriebsrad 7 sitzt - gleichachsig mit diesem gelagert - ein Kettenritzel 18. Über das Kettenritzel 18 läuft eine Antriebskette 13 zu dem in Figur 1 dargestellten unteren Antrieb. Der untere Antrieb entspricht in seinem grundsätzlichen Aufbau dem oberen Antrieb mit der Maßgabe, daß die Antriebsbewegung hier nicht über einen Motor und ein Getriebe, sondern über ein unteres Kettenritzel und die Antriebskette 13 in ein unteres Antriebsrad 27 eingeleitet wird. Das Antriebsrad 27 steht mit dem Gegenrad 28 über entsprechende Zahnradbereiche im formschlüssigen Eingriff. Auf dem schwenkbar gelagerten unteren Rollenträger 25 sitzen Führungsrollen 29 und 30.A chain sprocket 18 is seated on the drive wheel 7, mounted coaxially with the latter. A chain drive 13 runs over the chain sprocket 18 to the lower drive shown in FIG. The lower drive corresponds in its basic structure to the upper drive with the proviso that the drive movement is not initiated via a motor and a transmission, but via a lower chain sprocket and the drive chain 13 into a lower drive wheel 27. The drive wheel 27 is in positive engagement with the counter wheel 28 via corresponding gear areas. Guide rollers 29 and 30 are seated on the pivotably mounted lower roller carrier 25.

Bei der zweiten Ausführungsform gemäß Figuren 4 bis 5b erfolgt der Antrieb mittels eines Motors 3 über ein Getriebe 4 auf ein Doppelkettenrad 35. Von diesem Doppelkettenrad wird die Antriebskraft mittels der Doppelkette 33 auf ein weiteres Doppelkettenrad 34 übertragen. Die Drehachse des Doppelkettenrades 34 ist gleichzeitig die Schwenkachse für den Rollenträger 5', der schwenkbar am Fahrgestell 6' befestigt ist. Über ein gleichachsig mit dem Doppelkettenrad 34 angetriebenes Kettenrad 37 erfolgt der Antrieb eines zentralen Kettenrades 38, das seinerseits im Eingriff mit einem am Antriebsrad 7' und am Gegenrad 8' drehfest gelagerten Zahnradbereich im Eingriff steht. Über ein Kettenrad 37 und eine Kette 36 erfolgt der Antrieb eines Kettenrades 39, das seine Drehbewegung in analoger Weise auf das Antriebsrad 27' und das Gegenrad 28' auf dem unteren schwenkbaren Rollenträger 25' überträgt, wie dies beim oberen Rollenträger 5' das Kettenrad 37 tut.In the second embodiment according to FIGS. 4 to 5b, the drive by means of a motor 3 takes place via a gear 4 to a double sprocket 35. From this double sprocket, the driving force is transmitted to a further double sprocket 34 by means of the double chain 33. The axis of rotation of the double chain wheel 34 is also the pivot axis for the roller carrier 5 ', which is pivotally attached to the chassis 6'. A central sprocket 38 is driven via a sprocket 37 driven coaxially with the double sprocket 34, which in turn is in engagement with a gearwheel region mounted on the drive wheel 7 'and on the counter wheel 8' in a rotationally fixed manner. A sprocket 39 and a chain 36 drive a sprocket 39, which transmits its rotational movement in an analogous manner to the drive wheel 27 ′ and the counter wheel 28 ′ on the lower pivotable roller carrier 25 ′, as does the sprocket 37 in the upper roller carrier 5 ′ does.

Der obere Rollenträger 5' besitzt einen Hebelarm 31. Der untere Rollenträger 25' besitzt einen Hebelarm 32.The upper roller carrier 5 'has a lever arm 31. The lower roller carrier 25' has a lever arm 32.

An den freien Enden der beiden Hebelarme 31 und 32 ist ein längenveränderlicher Hebel 40 angeordnet. Der längenveränderliche Hebel besteht aus einem Rohr 40a, das einen Zapfen 40b eng, jedoch gleitbar umschließt. Eine Druckfeder 41 versucht den Hebel 40 zu verlängern und verschwenkt dabei durch Angriff an den Hebelarmen 32 und 31 die beiden Rollenträger 5' und 25' gegensinnig gegeneinander. Dabei werden Antriebsrad 7' und Gegenrad 8' sowie Antriebsrad 27' und Gegenrad 28' gegen die zugehörigen Fahrbahnprofile 1 und 2 gepreßt.A variable-length lever 40 is arranged at the free ends of the two lever arms 31 and 32. The variable-length lever consists of a tube 40a, which tightly encloses a pin 40b, but slidably. A compression spring 41 tries to extend the lever 40 and pivots the two roller carriers 5 'and 25' in opposite directions by attacking the lever arms 32 and 31. The drive wheel 7 'and counter wheel 8' and drive wheel 27 'and counter wheel 28' are pressed against the associated roadway profiles 1 and 2.

In Figuren 6 bis 8 ist eine weitere Ausführungsform als sogenannte Stuhlanlage dargestellt. Auch bei dieser Anlage erfolgt der Antrieb über einen Motor 3 und ein Getriebe 4 treibt ein Antriebsrad 7'' an, das fest mit einem Zahnradbereich 11'' verbunden ist. Der Zahnradbereich 11'' kämmt mit einem Zahnradbereich 12'', der fest mit einem Gegenrad 8'' verbunden ist.FIGS. 6 to 8 show a further embodiment as a so-called chair system. In this system too, the drive takes place via a motor 3 and a gear 4 drives a drive wheel 7 ″, which is firmly connected to a gearwheel region 11 ″. The gear area 11 ″ meshes with a gear area 12 ″, which is fixedly connected to a counter gear 8 ″.

Die Drehbewegung des Antriebsrads 7'' wird auf ein Kettenrad 42 übertragen und von dort über eine Kette 43 auf ein unteres Kettenrad 44. Dieses untere Kettenrad 44 ist drehfest verbunden mit dem unteren Antriebsrad 27'', durch dessen Mittelpunkt die Schwenkachse für einen unteren Rollenträger 45 läuft. Der untere Rollenträger 45 besitzt eine relativ kleine Gegenrolle 28''.The rotational movement of the drive wheel 7 ″ is transmitted to a sprocket 42 and from there via a chain 43 to a lower sprocket 44. This lower sprocket 44 is non-rotatably connected to the lower drive wheel 27 ″, through the center of which the pivot axis for a lower roller carrier 45 is running. The lower roller carrier 45 has a relatively small counter roller 28 ″.

Das obere Antriebsrad 7'' und das zugehörige Gegenrad 8'' sind auf einem oberen Rollenträger 46 gelagert. Zwischen dem oberen Rollenträger 46 und dem unteren Rollenträger 45 ist ein geringfügig in seiner Länge veränderbarer Hebel 40' angeordnet. Der Hebel 40' besteht aus einem Rohr 40a' und einem Kolben 40b'. Eine Druckfeder 41' versucht den Abstand zwischen den Anlenkpunkten zu vergrößern und drückt dabei die Antriebsräder fest gegen die als Rohre ausgebildeten Fahrbahnprofile 1 und 2.The upper drive wheel 7 ″ and the associated counter wheel 8 ″ are mounted on an upper roller carrier 46. Between the upper roller carrier 46 and the lower roller carrier 45, a lever 40 'which is slightly variable in length is arranged. The lever 40 'consists of a tube 40a' and a piston 40b '. A compression spring 41 'tries to increase the distance between the articulation points and in doing so presses the drive wheels firmly against the carriageway profiles 1 and 2 designed as tubes.

Die Zeichnungsfiguren 9 und 10 zeigen einen Vertikalaufzug mit zwei nebeneinander angeordneten Fahrbahnprofilen 1' und 2', die an einer vertikalen Wand befestigt sind. Von dem Fahrstuhlkorb ist lediglich der Rahmen 48 dargestellt. Der Rahmen besitzt an seinem unteren Ende zwei parallel zur vertikalen Wand verlaufende Laufrollen 49 und 50 sowie zwei weitere, dazu um 90° verdreht angeordnete Führungsrollen 51 und 52.The drawing figures 9 and 10 show a vertical elevator with two adjacent lane profiles 1 'and 2', which are attached to a vertical wall. Only the frame 48 of the elevator cage is shown. At its lower end, the frame has two rollers 49 and 50 running parallel to the vertical wall and two further guide rollers 51 and 52 which are rotated by 90 °.

Am oberen Ende des Rahmens 48 ist der Antrieb gelagert. Er besteht aus einem Motor 3 mit Getriebe 4. Das Getriebe 4 verdreht ein Antriebsrad 7''', das über eine Kette 53 mit einem Antriebsrad 27 '''gekoppelt ist.Das Antriebsrad 7''' ist mit dem Gegenrad 8''' auf einem Rollenträger schwenkbar gelagert, der einen Hebelarm 31''' aufweist.

Zwischen den beiden freien Enden der Hebelarme 31''' und 32''' ist der längenveränderliche Hebel 40''' angeordnet, der in gleicher Weise ausgestaltet ist wie der Hebelarm 40 bei der Ausführungsform gemäß Figuren 4 und 5a.The drive is mounted at the upper end of the frame 48. It consists of a motor 3 with a transmission 4. The transmission 4 rotates a drive wheel 7 '' 'which is coupled via a chain 53 to a drive wheel 27' ''. The drive wheel 7 '' 'is connected to the counter wheel 8' '' pivotally mounted on a roller carrier, which has a lever arm 31 '' '. The drive wheel 27 '' 'is mounted with the counter wheel 28' '' on a roller carrier 25 '' 'on which the lever arm 32' '' is seated. Between the two free ends of the lever arms 31 '' 'and 32' '' is the lever 40 '' 'which is variable in length and which is configured in the same way as the lever arm 40 in the embodiment according to FIGS. 4 and 5a.

Figuren 11 bis 13 zeigen einen Vertikalaufzug mit zwei auf unterschiedlichen Seiten des Fahrstuhlschachtes neben dem Fahrkorb 54 angeordneten Fahrbahnprofilen 1'' und 2''. Die Fahrbahnprofile sind bei dieser Ausführungsform als T-Profile ausgebildet. An den T-Profilen laufen einerseits die Antriebsräder 7'''' und 8'''' und andererseits die Antriebsräder 27'''' und 28'''' ab, die auf entsprechenden Rollenträgern angeordnet sind. Der Rollenträger 5''' ist verschwenkbar gelagert. Beim Verschwenken werden das Antriebsrad 7'''' und das Gegenrad 8'''' von unterschiedlichen Seiten fest gegen den Mittelschenkel des T-Profils 1'' gedrückt. Das Verschwenken erfolgt mit Hilfe des längenveränderlichen Hebels 40''', der am Hebelarm 31''' angreift und sich mit seinem anderen Ende gelenkig am Rahmen des Fahrkorbs abstützt.FIGS. 11 to 13 show a vertical elevator with two lane profiles 1 ″ and 2 ″ arranged on different sides of the elevator shaft next to the elevator car 54. In this embodiment, the roadway profiles are designed as T-profiles. On the one hand run on the T-profiles the drive wheels 7 '''' and 8 '''' and on the other hand the drive wheels 27 '''' and 28 '''', which are arranged on corresponding roller carriers. The roller carrier 5 '''is pivotally mounted. When pivoting, the drive wheel 7 '''' and the counter wheel 8 '''' are pressed from different sides firmly against the center leg of the T-profile 1 ''. The pivoting takes place with the help of the variable-length lever 40 ''', which engages the lever arm 31''' and is articulated with its other end on the frame of the car.

Der Antrieb erfolgt mittels eines Motors 3, dem ein Getriebe 4' mit zwei zu unterschiedlichen Seiten anschliessenden Abtriebswellen nachgeschaltet ist. Am Ende der Abtriebswelle 55''' ist das Antriebsrad 7'''' angeordnet, am Ende der Abtriebswelle 56''' das Antriebsrad 27''''. Die Antriebsräder sind über damit fest verbundenen und miteinander im Eingriff stehende Zahnradbereiche gekoppelt.The drive takes place by means of a motor 3, which is followed by a gear 4 'with two output shafts connecting to different sides. At the end of the output shaft 55 '' 'the drive wheel 7' '' 'is arranged, at the end of the output shaft 56' '' the drive wheel 27 '' ''. The drive wheels are coupled via gear areas which are firmly connected to and mesh with one another.

In den Zeichnungsfiguren 14 bis 16 sind drei unterschiedliche Arten von Rollenträgern mit auf unterschiedliche Art über Federn vorgespannten Antriebsrädern dargestellt:
Bei Figur 14 ist ein Rollenträger 57 vorgesehen, in dem das Antriebsrad 7, das Gegenrad 8 sowie die Führungsrolle 9 gelagert sind. Gleichachsig mit der Führungsrolle ist ein Flansch 60 verschwenkbar gelagert, auf dem wiederum eine Führungsrolle 10 gegenüber der Führungsrolle 9 gelagert ist. Am Flansch 60 greift eine Druckfeder 17 an, die andererseits gelenkig am Rollenträger 57 gelagert ist.In the drawing figures 14 to 16 three different types of roller carriers are shown with drive wheels prestressed in different ways via springs:
In Figure 14, a roller carrier 57 is provided, in which the drive wheel 7, the counter wheel 8 and the guide roller 9 are mounted. A flange 60 is pivotally mounted coaxially with the guide roller, on which in turn a guide roller 10 is mounted relative to the guide roller 9. A compression spring 17 acts on the flange 60 and is on the other hand articulated on the roller carrier 57.

Bei der Ausführungsform gemäß Figur 15 ist der Rollenträger 58 um eine Schwenkachse 60 verschwenkbar gelagert. Das Zentrum der Schwenkachse verläuft durch das Zentrum des Fahrbahnprofils. Eine Spiralfeder 61 ist in ihrem Zentrum an der Schwenkachse 60 befestigt und mit ihrem äußeren Ende mit Abstand von der Schwenkachse am Rollenträger 58 oder einem damit fest verbundenen Bereich.In the embodiment according to FIG. 15, the roller carrier 58 pivotally mounted about a pivot axis 60. The center of the swivel axis runs through the center of the lane profile. A coil spring 61 is fastened at its center to the pivot axis 60 and with its outer end at a distance from the pivot axis on the roller carrier 58 or an area firmly connected to it.

Bei der Ausführungsform gemäß Figur 16 ist ein Rollenträger 59 vorgesehen, der ebenfalls um eine Schwenkache 60 verschwenkbar ist, deren Zentrum sich durch das Zentrum des Fahrbahnprofils erstreckt. Das Gegenrad 8 ist auf einem Exzenterbolzen gelagert, an dem ein Hebel 16 angreift. Zwischen dem freien Ende des Hebels 16 und dem Rollenträger 59 ist eine Druckfeder 17 angeordnet.In the embodiment according to FIG. 16, a roller carrier 59 is provided, which is also pivotable about a pivot axis 60, the center of which extends through the center of the roadway profile. The counter wheel 8 is mounted on an eccentric bolt on which a lever 16 engages. A compression spring 17 is arranged between the free end of the lever 16 and the roller carrier 59.

Die unterschiedlichen Antriebseinheiten gemäß Figuren 14 bis 16 können statt der im Zusammenhang mit Figuren 1 bis 13 beschriebenen Antriebslösungen verwendet werden.The different drive units according to FIGS. 14 to 16 can be used instead of the drive solutions described in connection with FIGS. 1 to 13.

Die Anpressung der Laufrollen führt bei deren Ausbildung aus Metall, also bei einer Werkstoffpaarung Metall auf Metall dazu, daß das Trägerrohr im Bereich der Antriebsrollen unter dem Einfluß des Anpreßdrucks nach innen gedrückt wird. Bei praktischen Ausführungen wird eine eingedrückte Stelle, sogenannte "Delle", gebildet, in deren Bereich das Trägerrohr einen Durchmesser aufweist, der etwa 1 mm kleiner ist, als der Durchmesser des unbelasteten Rohres. Beim Fahrvorgang wandert die Delle über den gesamten Fahrweg mit. Das Fahrbahnrohr wird also während des Fahrvorgangs gewalkt. Die wandernde Delle wird unter der Eigenelastizität des Fahrbahnrohres nach Aufhebung der Anpreßbelastung durch die Antriebsrollen wieder ausgeglichen, so daß das Fahrbahnrohr außerhalb des Lastangriffs die ursprünglich kreiszylindrische Form mit dem ursprünglichen Durchmesser behält.When the rollers are formed from metal, that is to say when the metal is paired with metal, the support tube is pressed inward in the area of the drive rollers under the influence of the contact pressure. In the case of practical designs, an indented point, so-called "dent", is formed, in the area of which the carrier tube has a diameter which is approximately 1 mm smaller than the diameter of the unloaded tube. When driving, the dent moves along the entire route. The roadway tube is thus tumbled during the driving process. The wandering dent is compensated for under the inherent elasticity of the track tube after the contact pressure has been released by the drive rollers, so that the roadway tube retains the originally circular cylindrical shape with the original diameter outside the load attack.
