Hierbei sind lediglich Griffbereiche oder Gehäuseteile von einer Vibrationsquelle, wie von einem Schlagwerk, isoliert ausgeführt. Die Handwerkzeugmaschinen weisen dabei einen in der Regel eine Getriebeeinheit und eine Motoreinheit umfassenden Antriebsstrang auf.Hand tool machines, in particular rotary hammers, are already known, which have a decoupling unit for reducing vibration transmission. Here, only grip areas or housing parts of a vibration source, such as a percussion, isolated. The hand tool machines in this case have a drive train generally comprising a gear unit and a motor unit.

Die Erfindung geht aus von einer Handwerkzeugmaschine mit einem Antriebsstrang und mit wenigstens einer Entkopplungseinheit.The invention is based on a hand-held power tool with a drive train and with at least one decoupling unit.
Es wird vorgeschlagen, dass die Entkopplungseinheit zwischen zwei Antriebsstrangeinheiten angeordnet ist. Unter einer "Entkopplungseinheit" soll insbesondere eine Dämpfungseinheit und/oder eine Einheit zur Schwingungsisolierung verstanden werden. Ferner soll unter "zwischen" insbesondere eine Anordnung räumlich und/oder in einem Kraftfluss zwischen den Antriebsstrangeinheiten verstanden werden. Dadurch kann eine Entkopplung großer Massen, insbesondere eine Schwingungsentkopplung zwischen zwei Massen, erreicht werden. Damit verbunden kann die Vibration der Handwerkzeugmaschine und eine Vibrationsübertragung auf einen Bediener der Handwerkzeugmaschine reduziert werden.It is proposed that the decoupling unit is arranged between two drive train units. A "decoupling unit" is to be understood in particular as a damping unit and / or a unit for vibration isolation. Furthermore, under "between" in particular an arrangement spatially and / or in a power flow between the Antriebsstrangeinheiten be understood. Thereby, a decoupling of large masses, in particular a vibration decoupling between two masses can be achieved. Associated with this, the vibration of the power tool and a vibration transmission to an operator of the power tool can be reduced.
Vorteilhaft ist die Entkopplungseinheit zwischen einer Antriebseinheit und einer Getriebeeinheit des Antriebsstrangs angeordnet. Damit kann eine Reduzierung der Schwingungen in einer der beiden Abtriebseinheiten erzielt werden. Zudem kann durch diese Entkopplungseinheit eine längere Lebensdauer der elektrischen Komponenten in der schwingungsreduzierten Antriebseinheit der Handwerkzeugmaschine erreicht werden.Advantageously, the decoupling unit is arranged between a drive unit and a transmission unit of the drive train. This can be achieved a reduction in the vibrations in one of the two output units. In addition, a longer life of the electrical components in the vibration-reduced drive unit of the power tool can be achieved by this decoupling unit.
In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, dass eine Gehäuseeinheit der Antriebseinheit eine Koppelstelle zur Befestigung eines Zusatzhandgriffs aufweist. Unter einer "Koppelstelle" soll in diesem Zusammenhang insbesondere eine speziell ausgebildete, ausgestattete und/oder speziell vorgesehene Stelle zur Befestigung eines Zusatzhandgriffs verstanden werden, die vorzugsweise spezielle Befestigungsmittel aufweist, wie Ausnehmungen, Fortsätze usw. Dies kann vorteilhaft erreicht werden, indem die Gehäuseeinheit der Antriebseinheit in eine vorteilhafte Richtung verlängert wird. Der Vorteil hierbei ist, dass der Zusatzhandgriff an der schwingungsisolierten Antriebseinheit befestigt werden kann. So können beide Kontaktstellen des Bedieners mit der Handwerkzeugmaschine schwingungsentkoppelt werden.In a further embodiment of the invention, it is proposed that a housing unit of the drive unit has a coupling point for fastening an additional handle. A "coupling point" is to be understood in this context in particular a specially trained, equipped and / or specially provided location for attachment of an additional handle, which preferably has special fastening means, such as recesses, extensions, etc. This can be advantageously achieved by the housing unit of Drive unit is extended in an advantageous direction.

Vorteilhafterweise umfasst die Entkopplungseinheit wenigstens ein Entkopplungsmittel, das dazu vorgesehen ist, durch eine Verformung, vorzugsweise durch eine elastische Verformung, eine Entkopplung zu bewirken, wodurch ein Verschleiß in der Entkopplungseinheit durch äußere Reibung vermieden werden kann.Advantageously, the decoupling unit comprises at least one decoupling means, which is intended to effect a decoupling by a deformation, preferably by an elastic deformation, whereby a wear in the decoupling unit can be avoided by external friction.
Des Weiteren ist von Vorteil, wenn die Entkopplungseinheit ein balgförmiges Entkopplungsmittel aufweist, wodurch eine verschleißfreie Entkopplung, selbst bei hochfrequenten Relativbewegungen, und ein vorteilhafter Verformungsweg erreicht werden kann. Unter einem "balgförmigen" Entkopplungsmittel soll insbesondere ein zur Flächenerstreckung dünnwandiges, zumindest in Teilbereichen gefaltetes Entkopplungsmittel verstanden werden.Furthermore, it is advantageous if the decoupling unit has a bellows-shaped decoupling means, whereby a wear-free decoupling, even with high-frequency relative movements, and an advantageous deformation can be achieved. A "bellows-shaped" decoupling means should in particular be understood as meaning a decoupling means which is thin-walled for areal extent and which is folded at least in partial areas.
Ferner wird vorgeschlagen, dass das Entkopplungsmittel in zumindest einem Bereich eine Radialausrichtung aufweist. Dabei soll unter einer "Radialausrichtung" verstanden werden, dass zumindest eine Außenfläche und/oder eine Innenfläche des Entkopplungsmittels, insbesondere eine Wandung des Entkopplungsmittels, in ihrer Ausrichtung wenigstens eine radiale Komponente aufweist. Durch eine entsprechende Ausgestaltung kann eine in axialer Richtung besonders Platz sparende Bauweise erreicht werden.It is also proposed that the decoupling means has a radial orientation in at least one area. In this case, a "radial alignment" should be understood to mean that at least one outer surface and / or an inner surface of the decoupling means, in particular a wall of the decoupling means, has at least one radial component in its orientation. By appropriate design can a particularly space-saving construction in the axial direction can be achieved.
Vorteilhafterweise ist die Entkopplungseinheit zumindest teilweise einstückig mit einem weiteren Funktionsmittel ausgeführt, wodurch Bauteile, Bauraum, Gewicht, Montageaufwand und Kosten eingespart werden können. Unter einem "weiteren Funktionsmittel" sollen sämtliche, dem Fachmann als sinnvoll erscheinende Mittel verstanden werden, die insbesondere neben einer Entkopplung und/oder einer Kraftübertragung eine weitere Funktion aufweisen, wie insbesondere mitrotierende Funktionsmittel. Dabei bietet sich vorteilhaft eine Lüftereinheit an.Advantageously, the decoupling unit is at least partially designed in one piece with another functional means, whereby components, space, weight, assembly costs and costs can be saved. A "further functional agent" is to be understood as meaning any agent which appears appropriate to a person skilled in the art and which, in addition to a decoupling and / or a force transmission, has a further function, in particular co-rotating functional agent. This advantageously offers a fan unit.
In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, dass die Handwerkzeugmaschine eine wenigstens ein federbelastetes Führungsmittel umfassende Führungseinheit aufweist, die zur Führung zumindest einer der Antriebsstrangeinheiten vorgesehen ist. Es kann neben einer vorteilhaften Entkopplung eine in sich stabile Handwerkzeugmaschine erzielt werden.In a further embodiment of the invention, it is proposed that the handheld power tool has a guide unit comprising at least one spring-loaded guide means, which is provided for guiding at least one of the drive train units. It can be achieved in addition to an advantageous decoupling a stable hand machine tool.
Weist die Führungseinheit zumindest ein Entkopplungsmittel zur Lagerung eines Führungselements auf, können unerwünschte Schwingungsübertragungen über die Führungseinheit zumindest reduziert werden.If the guide unit has at least one decoupling means for mounting a guide element, unwanted vibration transmissions via the guide unit can at least be reduced.
Die erfindungsgemäße Lösung kann bei sämtlichen, dem Fachmann als geeignet erscheinenden Handwerkzeugmaschinen eingesetzt werden, jedoch besonders vorteilhaft bei Handwerkzeugmaschinen mit schlagenden Antriebsstrangeinheiten, wie insbesondere Bohrhämmern und Meiselhämmern usw.The solution according to the invention can be used in all hand-held power tools that appear to be suitable for the person skilled in the art, but particularly advantageous in hand-held power tools with beating drivetrain units, such as in particular rotary hammers and Meiselhämmern etc.
