Es wird vorgeschlagen, daß das Reibrad an der Antriebswelle gelagert und die Antriebswelle quer zur Bewegungsrichtung des Wagens ausgerichtet ist. Es können konstruktiv einfach mit einer Antriebswelle mehrere Reibräder angetrieben und dadurch ein besonders zuverlässiger Antrieb realisiert werden. Antriebskräfte können zumindest weitgehend symmetrisch eingebracht und ein Verkanten und Verklemmen kann sicher vermieden werden.It is proposed that the friction wheel be mounted on the drive shaft and the drive shaft is oriented transversely to the direction of movement of the carriage.

Ist die Antriebswelle in einem vorderen Gehäusebereich angeordnet, kann einfach erreicht werden, daß der Wagen vom Motor angetrieben von seiner inneren Endstellung bis zu seiner äußeren Endstellung ausgefahren und von der äußeren Endstellung bis zur inneren Endstellung eingefahren werden kann. Der Motor ist dagegen vorteilhaft in einem hinteren Gehäusebereich angeordnet, wo dieser in einem in der Regel noch freien Bauraum geschützt, außerhalb des Sichtfelds, angeordnet werden kann. Der Motor und die Antriebswelle können dabei über verschiedene, dem Fachmann als sinnvoll erscheinende Verbindungselemente antriebsmäßig verbunden sein, beispielsweise über eine Kette, eine Welle usw. Besonders vorteilhaft ist der Motor jedoch über einen Zahnriemen mit der Antriebswelle verbunden, wodurch ein besonders leiser und kostengünstiger Antrieb realisiert werden kann. Ferner kann durch eine Elastizität des Zahnriemens ein sanftes Anfahren und Abbremsen des Wagens unterstützt werden.If the drive shaft is arranged in a front housing area, it can be easily reached be that the car is driven by the engine from its inner end position to extended to its outer end position and from the outer end position to the inner End position can be retracted. The engine, on the other hand, is advantageous in one arranged rear housing area, where this is usually still free space protected, outside the field of view, can be arranged. The engine and the The drive shaft can have various types that appear useful to the person skilled in the art Connecting elements connected in terms of drive, for example via a chain, a shaft, etc. The motor is particularly advantageous via a toothed belt with the Drive shaft connected, resulting in a particularly quiet and inexpensive drive can be. In addition, the elasticity of the toothed belt enables smooth starting and braking the car are supported.

Ist das Reibrad im Gehäuse angeordnet, können für die bewegbare Lagerung erforderliche Lagerelemente und die Kraft erzeugenden Mittel vorteilhaft im Gehäuse angeordnet werden. Grundsätzlich könnte jedoch auch das die Lauffläche bildende Bauteil bewegbar gelagert und mit einer Kraft in Richtung des Reibrads belastet sein. Die die Kraft erzeugenden Mittel können von verschiedenen, dem Fachmann als sinnvoll erscheinenden Bauteilen gebildet sein, beispielsweise von einem elektromagnetischen Aktuator, der abhängig von unterschiedlich schweren Ladungen unterschiedliche Anpreßkräfte erzeugen kann, und/oder vorteilhaft von Federelementen usw.

In principle, however, the component forming the tread could also be moved be stored and loaded with a force in the direction of the friction wheel. The ones generating the force Means can be of various types which appear useful to the person skilled in the art Components are formed, for example by an electromagnetic actuator, which is dependent generate different contact forces from loads of different weights can, and / or advantageously of spring elements, etc.

In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, daß das Reibrad vertikal von unten nach oben auf die Lauffläche wirkt. Die Antriebswelle und das Reibrad können platzsparend unter dem Backwagen integriert werden. Ferner kann die das Reibrad belastende Kraft einfach abhängig von einer Gewichtskraft des Wagens bzw. abhängig von einer Gewichtskraft einer Ladung des Wagens gestaltet werden, und zwar indem beispielsweise aufgrund elastischer Verformung tragender Teile der Wagen mit einer größeren Kraft auf das Reibrad wirkt und dabei Federn weiter zusammengedrückt werden, die das Reibrad mit der Kraft belasten, oder indem abhängig von einer über eine Sensoreinheit erfaßten Gewichtskraft die das Reibrad belastende Kraft durch einen elektromagnetischen Aktuator erhöht wird. Das Reibrad kann mit großen Kräften belastet werden, ohne daß unvorteilhafte Führungskräfte entstehen, vielmehr können erhöhte Belastungen von Laufrollen des Wagens bei schweren Ladungen durch die das Reibrad belastende Kraft zumindest teilweise kompensiert werden.In a further embodiment of the invention it is proposed that the friction wheel be vertical acts on the tread from bottom to top.

In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, daß der Motor über eine elektronische Steuereinheit steuerbar ist. Das Antriebsmoment des Motors kann stets vorteilhaft auf die Gewichtskraft des Wagens abgestimmt und insbesondere kann stets ein besonders sanftes Anfahren und Abbremsen des Wagens erreicht werden. Die Gewichtskraft des Wagens kann über verschiedene, dem Fachmann als sinnvoll erscheinende Sensoren ermittelt werden, beispielsweise über einen Kraftsensor und/oder über einen Beschleunigungssensor, über den ein Beschleunigungswert des Wagens ermittelt und vom ermittelten Beschleunigungswert und einem vorliegenden Antriebsmoment auf eine Gewichtskraft des Wagens geschlossen werden kann, usw.In a further embodiment of the invention it is proposed that the motor an electronic control unit is controllable.

Ferner können mit einem über eine elektronische Steuereinheit gesteuerten Motor konstruktiv einfach Sicherheitsfunktionen beim Ausfahren und beim Einfahren erreicht werden, beispielsweise indem der Motor über die Steuereinheit gestoppt wird, sobald ein bestimmtes Antriebsmoment überschritten wird. Grundsätzlich sind jedoch auch andere, dem Fachmann als sinnvoll erscheinende Sicherheitsvorrichtungen denkbar, beispielsweise mit einem elektromagnetischen Aktuator, der eine Kupplung öffnet, sobald über einen Sensor ein außergewöhnlicher Betriebszustand erfaßt wird.Furthermore, constructive with a motor controlled by an electronic control unit simple safety functions can be achieved when extending and retracting, for example by stopping the engine via the control unit as soon as a certain one Drive torque is exceeded. Basically, however, there are others Safety devices that appear sensible to a person skilled in the art are conceivable, for example with an electromagnetic actuator that opens a clutch as soon as over a sensor detects an unusual operating condition.
Um stets gewährleisten zu können, daß der Wagen ein- und ausgefahren werden kann, ist dieser vorteilhaft im Gehäuse manuell verfahrbar bzw. ist der Motor und möglicherweise ein mit dem Motor verbundenes Getriebe nicht selbsthemmend ausgeführt.In order to always be able to ensure that the car can be retracted and extended, is this advantageously manually movable in the housing or is the motor and possibly a gearbox connected to the engine is not self-locking.
