Description

Kettensägen mit Benzinmotorenantrieb, bei denen zwischen Motor und Sägevorrichtung eine Reibungskupplung eingebaut ist und deren Betätigungsorgan derart ausgeführt ist, daß die Kupplung sowie die Regulierung der Tourenzahl des Äiotors von einem Handgriff aus geschieht, sind bekannt, haben aber den Nachteil, daß der gemeinsame Handgriff schwer zu bedienen ist. Die Regulierung der Tourenzahl, welche bekanntlich durch den Vergaserhebel geschieht, ist ohne jede Kraftanstrengung möglich, dagegen erfordert das Einrücken der Kupplung eine größere Kraftaufwendung, da die Kupplung ja nur, wenn ein genügend großer Anpressungsdruck vorhanden ist, die Kraft übertragen kann.Chainsaws with petrol engine drive, where between the engine and the sawing device a friction clutch is installed and its actuator is designed in this way is that the clutch as well as the regulation of the number of revolutions of the Äiotors from a handle happens from, are known, but have the disadvantage that the common handle difficult to use. The regulation of the number of tours, which is known by the Carburetor lever happens, is possible without any effort, but it requires Engaging the clutch requires more force, since the clutch only applies when there is sufficient contact pressure that can transmit force.

Zur Erleichterung der Bedienung wird nachFor ease of use is after

der Erfindung die Reibungskupplung durch eine besondere Fliehkraftkupplung ersetzt.the invention replaced the friction clutch by a special centrifugal clutch.

Der Benzinmotor wird von Hand auf eine gewisse Leerlauftourenzahl eingestellt. Die Fliehkraft der Kupplung, entsprechend der Leerlauftourenzahl, wird durch abgestimmte Druckfedern so ausgeglichen, daß ein Kupp-The petrol engine is set by hand to a certain number of idling speeds. the Centrifugal force of the clutch, corresponding to the number of idling revs, is coordinated by Compression springs so balanced that a coupling

as lungsschluß nicht auftritt, dagegen bei der Regelung des Motors auf höhere Touren die Kupplung sich einschaltet bzw. bei Drosselung und Wiedererlangen der Leerlauftourenzahl ausschaltet.The conclusion does not occur, however with the Regulation of the engine at higher speeds, the clutch switches on or when throttling and regaining the idle speed turns off.

In der Zeichnung ist der Erfmdungsgegenstand dargestellt.The subject of the invention is shown in the drawing.

α ist das Kurbelwellenende des Motors, b die Kupplungsachse, c ist mit Führungen d für die Fliehgewichte e versehen, welche mittels Bremsbelag h mit dem Kupplungsgehäuse f den Kupplungsschluß vermitteln. α is the crankshaft end of the engine, b the clutch axis, c is provided with guides d for the flyweights e , which mediate the clutch connection by means of brake lining h with the clutch housing f.
