Abstract

A hand-held working machine (100) comprises at least one combustion engine (12) and a voltage generator (11) for the engine. The voltage generator also functions as a starter to start the combustion engine. Preferably the machine is electrically connected to an additional voltage source (14) for starting.

Description

Die Erfindung betrifft eine handgehaltene Arbeitsmaschine, insbesondere Kettensäge, Heckenschere, Laubgebläse, Rasenkantenschneider oder dergleichen mit wenigstens einem Verbrennungsmotor, der eine Versorgungsspannung benötigt und einem Spannungsgenerator, der eine Generatorspannung abgibt, die zur Erzeugung der Versorgungsspannung dient.The The invention relates to a hand-held work machine, in particular Chainsaw, Hedge trimmer, leaf blower, Lawn edger or the like with at least one internal combustion engine, who needs a supply voltage and a voltage generator that outputs a generator voltage, which is used to generate the supply voltage.

Handgehaltene Arbeitsmaschinen mit einem Verbrennungsmotor werden mit Seilzug-betätigten Startsystemen ausgerüstet. Diese sind mechanisch aufwendig und verschleißanfällig. Zudem behindern die Startsysteme einen optimalen Kühlluftstrom. Mit der Forderung, höhere Startergeschwin digkeiten bei geringeren Zugkräften zu realisieren, wird der Bauaufwand und die Verschleißanfälligkeit größer.hand-held Working machines with an internal combustion engine are operated with cable-operated starting systems equipped. These are mechanically complex and prone to wear. In addition, the starting systems hinder an optimal cooling air flow. With the demand higher Realizing starter speeds with lower tractive forces is the Construction effort and susceptibility to wear greater.

Es ist daher Aufgabe der Erfindung, das Startsystem solcher Arbeitsmaschine zu optimieren.It is therefore the object of the invention, the starting system of such a machine to optimize.

Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.This The object is achieved by the features specified in claim 1.

Es wird hierbei der Einsatz eines im Automobilbereich eingesetzten Startergenerators für handgehaltene und damit tragbare Arbeitsmaschinen vorgeschlagen. Der Vorteil besteht darin, dass die Betätigungskräfte für eine solche Maschine minimiert werden, wobei der Startergenerator keinem mechanischen Verschleiß unterliegt.It is used here in the automotive sector Starter generator for hand-held and therefore portable work machines proposed. The advantage is that the operating forces for such a machine are minimized the starter generator is not subject to mechanical wear.

Ein Ausführungsbeispiel wird anhand der beigefügten Zeichnung näher erläutert. 1 zeigt eine dreidimensionale Ansicht einer erfindungsgemäßen handgehaltenen Arbeitsmaschine in Form einer Kettensäge.An embodiment is explained in more detail with reference to the accompanying drawing. 1 shows a three-dimensional view of a hand-held work machine according to the invention in the form of a chainsaw.

Bei dem Ausführungsbeispiel der Arbeitsmaschine 100 in der Figur ist innerhalb des Gehäuses 10 ein in der Zeichnung nicht dargestellter Startergenerator 11 angeordnet, der mit dem Verbrennungsmotor 12 verbunden ist.In the embodiment of the work machine 100 in the figure is inside the case 10 a starter generator, not shown in the drawing 11 arranged with the internal combustion engine 12 connected is.

Mittels des Schalters 13 wird die nicht dargestellte Zündeinrichtung freigeschaltet, so dass der Verbrennungsmotor 12 gestartet werden kann. Der Schalter 13 ist bevorzugterweise mit einer zusätzlichen Tippstellung ausgestaltet, bei der der Startergenerator 11 betätigbar ist.Using the switch 13 the ignition device, not shown, is activated so that the internal combustion engine 12 can be started. The desk 13 is preferably designed with an additional tip position in which the starter generator 11 can be actuated.

Bei der dargestellten Ausführungsform 100 ist diese mit einer integrierten zusätzlichen Spannungsquelle 14 ausgestattet. Diese ist unter einer Abdeckung des Gehäuses 10 angeordnet. Hierbei kann es sich um einen Akkumulator 14a oder um eine Batterie 14b handeln, die in einem Aufnahmefach 15 angeordnet sind.In the illustrated embodiment 100 is this with an integrated additional voltage source 14 fitted. This is under a cover of the housing 10 arranged. This can be an accumulator 14a or a battery 14b act that in a tray 15 are arranged.

Es ist auch möglich, die elektrische Versorgung des Startergenerators über einen elektrischen Stecker mit entsprechenden Steckkontakten zu realisieren.It is possible, too, the electrical supply to the starter generator via a to realize electrical plugs with corresponding plug contacts.
