Abstract

Rasenmäher mit Radantrieb, dadurch gekennzeichnet, daß der Motor neben dem Messer noch einen Generator antreibt, dessen Rotor unter dem Motor, an der Antriebswelle des Messers befestigt ist, und mit dieser zusammen in Rotation versetzt wird, und der Generator den erzeugten Strom an Radnabenelektromotore abgiebt, die in zwei, oder auch in vier Rasenmäherräder eingebaut werden, und der Rasenmäher durch Betätigen eines Schalters, der den Strom umpolt, auf Rückwärtsfahrt geschaltet werden kann.Wheel drive lawnmower, characterized in that the motor drives a generator in addition to the knife, the rotor of which is attached to the drive shaft of the knife under the motor and is set in rotation with it, and the generator delivers the generated electricity to wheel hub electric motors that are built into two or four lawnmower wheels, and the lawnmower can be switched to reverse by pressing a switch that reverses the polarity.

Description

Herkömmliche Benzinrasenmäher benötigen für den mechanischen Radantrieb relativ viel Platz an der Unterseite des Rasenmähers, wodurch die Abfuhr des Mähgutes durch das Messer behindert wird. Auserdem haben dicht über dem Boden rotierende Antriebswellen die Tendenz, sich mit Gras und Gestrüpp zu umwickeln, was ihre Funktion beinträchtigen kann. Ein weiterer Mangel ist, daß nur Vorwärtsfahrt möglich ist, Rückwärtsfahrt geht nur mit Muskelkraft, was, vor allem bei unebenem Gelände, anstrengend ist. Die Erfindung macht es sich zur Aufgabe, diese Mängel zu beheben. Erfindungsmäßig wird dies dadurch gelöst, daß der Motor, neben dem Messer, noch einen Generator antreibt, dessen Rotor unter dem Motor, an der Antriebswelle des Messers befestigt ist, und mit dieser zusammen in Rotation vesetzt wird, und der Generator den erzeugten Strom an Radnabenelektromotore abgiebt, die in zwei, oder auch in vier Rasenmäherräder eingebaut werden, und der Rasenmäher durch betätigen eines Schalters der den Strom umpolt, auf Rückwärtsfahrt geschaltet werden kann. Dieses Antiebsprinzip ist natürlich nicht nur für handgeführte Rasenmäher geeignet sondern ebenso für Rasentraktoren.Conventional petrol lawnmowers require relatively much space for the mechanical wheel drive at the bottom of the lawnmower, whereby the removal of the crop is obstructed by the knife. In addition, drive shafts rotating just above the ground tend to wrap around with grass and scrub, which can impair their function. Another shortcoming is that only forward driving is possible, reversing is only possible with muscle power, which, especially on uneven terrain, is exhausting. The invention makes it its mission to remedy these shortcomings. According to the invention this is achieved in that the motor, in addition to the knife, still drives a generator whose rotor is mounted under the engine, on the drive shaft of the knife, and is used together with this in rotation, and the generator generates the generated current to Radnabenelektromotore abgiebt that are installed in two, or even in four lawn mower wheels, and the lawn mower by pressing a switch that reverses the current, can be switched to reverse. This Antiebsprinzip is of course not only suitable for hand-held lawn mower but also for lawn tractors.

Die genial einfache Erfindung des Radnabenelektromotors gelang Ferdinand Porsche bereits vor dem ersten Weltkrieg. Mit ihr läst sich mit relativ geringem Aufwand ein vierradgetriebener Rasenmäher verwirklichen. Die Zeichnung zeigt unter 1 die schematische Darstellung der Motor-Generator-Messer-Anordnung. 2 zeigt ein Rasenmäherrad mit eingebautem Radnabenelektromotor im Schnitt, wobei 1 der Rasenmäher ist, 2 die an ihm befestigte Radachse, 3 zeigt den auf der Achse befestigten Stator des E-Motors, 4 den im Rad befestigten Rotor des E-Motors, 5 einen Arretierungsstift für den Rotor, 6 die in das Rad eingeschraubte Rückwand des Rades, die gleichzeitig den Rotor festhält, 7 die beiden Kugellager des Rades, und 8 die Halteschraube für das Rad.The ingeniously simple invention of the wheel hub electric motor succeeded Ferdinand Porsche already before the First World War. With her you can realize with relatively little effort a four-wheel drive lawnmower. The drawing shows below 1 the schematic representation of the motor-generator-knife assembly. 2 shows a lawn mower with built-wheel hub electric motor in section, where 1 the lawnmower is, 2 the wheel axle attached to it, 3 shows the stator of the electric motor mounted on the axle, 4 the rotor of the electric motor mounted in the wheel, 5 a locking pin for the rotor, 6 the rear wall of the wheel screwed into the wheel, which at the same time holds the rotor, 7 the two ball bearings of the wheel, and 8th the retaining screw for the wheel.
