Advantageously, all of the damping elements of the damping unit are at least essentially cylindrical, in particular circular cylindrical. The damping element and / or the damping elements are preferably designed in the form of a hollow cylinder. In this context, an “at least substantially cylindrical” object is to be understood as meaning in particular an object that deviates from a cylindrical reference object with a volume fraction of at most 30%, preferably at most 20% and particularly preferably at most 10%.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Figur 1 zeigt eine Handwerkzeugmaschine 10 in einer schematischen Darstellung. Die Handwerkzeugmaschine 10 ist als Oszillationshandwerkzeugmaschine ausgebildet. Die Handwerkzeugmaschine 10 ist als Multifunktionshandwerkzeugmaschine ausgebildet und insbesondere wahlweise zu einer Schleifbearbeitung, einer Fräsbearbeitung, einer Sägebearbeitung, einer Schneidbearbeitung und/oder einer Raspelbearbeitung vorgesehen. Die Handwerkzeugmaschine 10 ist motorisch betreibbar ausgebildet. Im vorliegenden Fall ist die Handwerkzeugmaschine 10 als eine Elektrohandwerkzeugmaschine ausgebildet. Die Handwerkzeugmaschine 10 ist dabei kabellos ausgebildet und somit insbesondere batteriebetrieben und/oder akkubetrieben. Alternativ ist denkbar, eine Handwerkzeugmaschine als beliebige andere Handwerkzeugmaschine auszubilden, wie beispielsweise als Bohrhammer, als Meißelhammer, als Schlagbohrmaschine, als Abbruchhammer, als Bohrmaschine, als Fräse, als Säge, als Akku-Schrauber und/oder als Gartengerät oder dergleichen. Zudem ist denkbar, eine Handwerkzeugmaschine kabelgebunden auszubilden und somit insbesondere netzbetrieben. Figure 1 shows a handheld power tool 10 in a schematic representation. The hand machine tool 10 is designed as an oscillation hand machine tool. The handheld power tool 10 is designed as a multifunctional handheld power tool and, in particular, optionally provided for grinding, milling, sawing, cutting and / or rasp processing. The handheld power tool 10 is designed to be operated by a motor. In the present case, handheld power tool 10 is designed as an electric handheld power tool. The handheld power tool 10 is designed to be cordless and thus in particular battery-operated and / or battery-operated. Alternatively, it is conceivable to design a handheld power tool as any other handheld power tool, such as a hammer drill, chisel hammer, impact drill, demolition hammer, drill, milling machine, saw, cordless screwdriver and / or garden tool or the like. It is also conceivable to design a handheld power tool to be wired and thus in particular to be network-operated.

Die Handwerkzeugmaschine 10 umfasst eine Gehäuseeinheit 46. Die Gehäuseeinheit 46 bildet ein Außengehäuse der Handwerkzeugmaschine 10. Innerhalb der Gehäuseeinheit 46 sind wenigstens ein Großteil der für einen Betrieb der Handwerkzeugmaschine 10 benötigten Bauteile angeordnet.The handheld power tool 10 comprises a housing unit 46. The housing unit 46 forms an outer housing of the handheld power tool 10. At least a large part of the components required for operating the handheld power tool 10 are arranged within the housing unit 46.

Die Gehäuseeinheit 46 umfasst ein Maschinengehäuse 14. Das Maschinengehäuse 14 ist als Außengehäuse ausgebildet. Das Maschinengehäuse 14 bildet im vorliegenden Fall einen vorderen Teil der Handwerkzeugmaschine 10. Innerhalb des Maschinengehäuses 14 sind wenigstens ein Großteil der für einen Antrieb der Handwerkzeugmaschine 10 benötigten Bauteile angeordnet.The housing unit 46 comprises a machine housing 14. The machine housing 14 is designed as an outer housing. In the present case, the machine housing 14 forms a front part of the handheld power tool 10. Inside of the machine housing 14, at least a large part of the components required for driving the handheld power tool 10 are arranged.

Das Maschinengehäuse 14 ist ferner zumindest zweiteilig ausgebildet und umfasst zwei Maschinengehäuseteile 34, 36. Die Maschinengehäuseteile 34, 36 weisen eine Schalenbauweise auf. Die Maschinengehäuseteile 34, 36 sind als Gehäuseschalen ausgebildet. Die Maschinengehäuseteile 34, 36 sind voneinander trennbar ausgebildet. Im vorliegenden Fall sind die Maschinengehäuseteile 34, 36 in eine Trennrichtung 32 voneinander trennbar. Die Maschinengehäuseteile 34, 36 sind somit zu einem Trennen und/oder zu einem Verbinden in die Trennrichtung 32 bewegbar. Die Trennrichtung 32 ist im vorliegenden Fall senkrecht zu einer Bearbeitungsebene und/oder einem Untergrund ausgerichtet. Demnach weisen die Maschinengehäuseteile 34, 36 eine horizontale Trennungsebene auf.The machine housing 14 is also formed in at least two parts and comprises two machine housing parts 34, 36. The machine housing parts 34, 36 have a shell design. The machine housing parts 34, 36 are designed as housing shells. The machine housing parts 34, 36 are designed to be separable from one another. In the present case, the machine housing parts 34, 36 can be separated from one another in a separating direction 32. The machine housing parts 34, 36 can thus be moved in the separating direction 32 for separating and / or for connecting. In the present case, the separation direction 32 is oriented perpendicular to a processing plane and / or a substrate. Accordingly, the machine housing parts 34, 36 have a horizontal plane of separation.

Darüber hinaus definiert das Maschinengehäuse 14 einen Griffbereich 40. Der Griffbereich 40 ist als Führungsgriffbereich ausgebildet. Der Griffbereich 40 ist auf einer einem Frontbereich zugewandten Seite der Handwerkzeugmaschine 10 angeordnet. Der Griffbereich 40 ist im vorliegenden Fall zumindest im Wesentlichen zu einem Führen der Handwerkzeugmaschine 10 vorgesehen. Prinzipiell könnte eine Trennrichtung jedoch auch parallel zu einer Bearbeitungsebene und/oder einem Untergrund ausgerichtet sein. Zudem könnte ein Maschinengehäuse dreiteilig und/oder vierteilig ausgebildet sein. Auch könnte ein Maschinengehäuse prinzipiell einstückig und/oder einteilig ausgebildet sein. Ferner könnte ein Maschinengehäuse und/oder wenigstens ein Maschinengehäuseteil auch eine Topfbauweise oder eine Kombination aus Schalenbauweise und Topfbauweise aufweisen. Zudem ist denkbar, dass ein Maschinengehäuse ein zusätzliches Griffelement zu einem Halten und/oder Führen einer Handwerkzeugmaschine aufweist und/oder, dass ein zusätzliches Griffelement zu einem Halten und/oder Führen der Handwerkzeugmaschine an dem Maschinengehäuse befestigbar ist.In addition, the machine housing 14 defines a grip area 40. The grip area 40 is designed as a guide grip area. The grip area 40 is arranged on a side of the handheld power tool 10 facing a front area. In the present case, the grip area 40 is provided at least essentially for guiding the handheld power tool 10. In principle, however, a separation direction could also be aligned parallel to a processing plane and / or a substrate. In addition, a machine housing could be designed in three parts and / or four parts. In principle, a machine housing could also be constructed in one piece and / or in one piece. Furthermore, a machine housing and / or at least one machine housing part could also have a pot construction or a combination of a shell construction and a pot construction. In addition, it is conceivable that a machine housing has an additional grip element for holding and / or guiding a handheld power tool and / or that an additional grip element for holding and / or guiding the handheld power tool can be fastened to the machine housing.

Darüber hinaus umfasst die Gehäuseeinheit 46 ein Kopplungsgehäuse 16. Das Kopplungsgehäuse 16 ist als Außengehäuse ausgebildet. Das Kopplungsgehäuse 16 ist separat von dem Maschinengehäuse 14 ausgebildet. Das Kopplungsgehäuse 16 bildet im vorliegenden Fall einen hinteren Teil der Handwerkzeugmaschine 10. Das Kopplungsgehäuse 16 ist zu einer Kopplung mit einer Energiespeichereinheit 18 vorgesehen. Dazu weist das Kopplungsgehäuse 16 eine Schnittstelle 48 zu einer Anbindung der, im vorliegenden Fall insbesondere als Akkupack ausgebildeten, Energiespeichereinheit 18 auf. Innerhalb des Kopplungsgehäuses 16 sind zudem wenigstens ein Großteil der für einen Betrieb der Energiespeichereinheit 18 benötigten Bauteile angeordnet.In addition, the housing unit 46 comprises a coupling housing 16. The coupling housing 16 is designed as an outer housing. The coupling housing 16 is formed separately from the machine housing 14. The coupling housing In the present case 16 forms a rear part of the handheld power tool 10. The coupling housing 16 is provided for coupling to an energy storage unit 18. For this purpose, the coupling housing 16 has an interface 48 for connecting the energy storage unit 18, which in the present case is designed in particular as a battery pack. In addition, at least a large part of the components required for operating the energy storage unit 18 are arranged within the coupling housing 16.

Das Kopplungsgehäuse 16 ist in einem montierten Zustand mit dem Maschinengehäuse 14 verbunden. Im vorliegenden Fall ist das Kopplungsgehäuse 16 dabei in einem, im vorliegenden Fall insbesondere zumindest im Wesentlichen zentral bezüglich der Handwerkzeugmaschine 10 angeordneten, Verbindungsbereich 24 mit dem Maschinengehäuse 14 verbunden. In dem Verbindungsbereich 24 umgreift das Kopplungsgehäuse 16 das Maschinengehäuse 14 vollständig.The coupling housing 16 is connected to the machine housing 14 in an assembled state. In the present case, the coupling housing 16 is connected to the machine housing 14 in a connection area 24, in the present case in particular arranged at least essentially centrally with respect to the handheld power tool 10. In the connection area 24, the coupling housing 16 completely surrounds the machine housing 14.

Das Kopplungsgehäuse 16 ist ferner zumindest zweiteilig ausgebildet und umfasst zwei Kopplungsgehäuseteile 26, 28 (vgl. auch Figur 2). Die Kopplungsgehäuseteile 26, 28 weisen eine Schalenbauweise auf. Die Kopplungsgehäuseteile 26, 28 sind als Gehäuseschalen ausgebildet. Die Kopplungsgehäuseteile 26, 28 sind voneinander trennbar ausgebildet. Im vorliegenden Fall sind die Kopplungsgehäuseteile 26, 28 in eine weitere Trennrichtung 30 voneinander trennbar (vgl. Figur 2). Die Kopplungsgehäuseteile 26, 28 sind somit zu einem Trennen und/oder zu einem Verbinden in die weitere Trennrichtung 30 bewegbar. Die weitere Trennrichtung 30 ist von der Trennrichtung 32 verschieden. Die weitere Trennrichtung 30 ist senkrecht zu der Trennrichtung 32 ausgerichtet. Die weitere Trennrichtung 30 ist im vorliegenden Fall parallel zu der Bearbeitungsebene und/oder dem Untergrund ausgerichtet. Demnach weisen die Kopplungsgehäuseteile 26, 28 eine vertikale Trennungsebene auf.The coupling housing 16 is also designed in at least two parts and comprises two coupling housing parts 26, 28 (cf. also Figure 2 ). The coupling housing parts 26, 28 have a shell construction. The coupling housing parts 26, 28 are designed as housing shells. The coupling housing parts 26, 28 are designed to be separable from one another. In the present case, the coupling housing parts 26, 28 can be separated from one another in a further separation direction 30 (cf. Figure 2 ). The coupling housing parts 26, 28 can thus be moved in the further separation direction 30 for separation and / or connection. The further separation direction 30 is different from the separation direction 32. The further separation direction 30 is oriented perpendicular to the separation direction 32. The further separation direction 30 is aligned in the present case parallel to the processing plane and / or the substrate. Accordingly, the coupling housing parts 26, 28 have a vertical separation plane.

Darüber hinaus definiert das Kopplungsgehäuse 16 einen weiteren Griffbereich 38. Der weitere Griffbereich 38 ist als Hauptgriffbereich ausgebildet. Der weitere Griffbereich 38 ist auf einer dem Frontbereich abgewandten Seite der Handwerkzeugmaschine 10 angeordnet. Der weitere Griffbereich 38 ist im vorliegenden Fall zumindest im Wesentlichen zu einem Halten der Handwerkzeugmaschine 10 vorgesehen. Prinzipiell könnte eine weitere Trennrichtung jedoch auch senkrecht zu einer Bearbeitungsebene und/oder einem Untergrund ausgerichtet sein. Zudem könnte ein Kopplungsgehäuse dreiteilig und/oder vierteilig ausgebildet sein. Auch könnte ein Kopplungsgehäuse prinzipiell einstückig und/oder einteilig ausgebildet sein. Ferner könnte ein Kopplungsgehäuse und/oder wenigstens ein Kopplungsgehäuseteil auch eine Topfbauweise oder eine Kombination aus Schalenbauweise und Topfbauweise aufweisen. Zudem ist denkbar, dass ein Kopplungsgehäuse ein zusätzliches Griffelement zu einem Halten und/oder Führen einer Handwerkzeugmaschine aufweist und/oder, dass ein zusätzliches Griffelement zu einem Halten und/oder Führen der Handwerkzeugmaschine an dem Kopplungsgehäuse befestigbar ist.In addition, the coupling housing 16 defines a further grip area 38. The further grip area 38 is designed as the main grip area. The further grip area 38 is arranged on a side of the handheld power tool 10 facing away from the front area. In the present case, the further grip area 38 is provided at least essentially to hold the handheld power tool 10. In principle, however, a further separation direction could also be perpendicular be aligned with a processing plane and / or a subsurface. In addition, a coupling housing could be designed in three parts and / or four parts. A coupling housing could in principle also be designed in one piece and / or in one piece. Furthermore, a coupling housing and / or at least one coupling housing part could also have a pot construction or a combination of a shell construction and a pot construction. It is also conceivable that a coupling housing has an additional grip element for holding and / or guiding a handheld power tool and / or that an additional grip element can be fastened to the coupling housing for holding and / or guiding the handheld power tool.

Insbesondere um eine Montage des Kopplungsgehäuses 16 an dem Maschinengehäuse 14 zu vereinfachen, umfasst die Handwerkzeugmaschine 10 zudem wenigstens ein Ausrichtelement 44 (vgl. insbesondere Figur 2). Im vorliegenden Fall umfasst die Handwerkzeugmaschine 10 zwei Ausrichtelemente 44, wobei insbesondere in den Figuren 2 bis 5 der Übersichtlichkeit halber lediglich eines der Ausrichtelemente 44 mit einem Bezugszeichen versehen ist. Die Ausrichtelemente 44 sind separat von dem Maschinengehäuse 14 ausgebildet. Zudem sind die Ausrichtelemente 44 separat von dem Kopplungsgehäuse 16 ausgebildet. Die Ausrichtelemente 44 bestehen aus Metall. Die Ausrichtelemente 44 sind zumindest im Wesentlichen baugleich zueinander. Die Ausrichtelemente 44 sind ferner stiftförmig ausgebildet. Die Ausrichtelemente 44 sind dabei zumindest im Wesentlichen hohlzylinderförmig ausgebildet. Im vorliegenden Fall, sind die Ausrichtelemente 44 als Zentrierstifte ausgebildet. Die Ausrichtelemente 44 sind zumindest dazu vorgesehen, bei einer Verbindung des Maschinengehäuses 14 und des Kopplungsgehäuses 16, das Maschinengehäuse 14 und das Kopplungsgehäuse 16 relativ zueinander auszurichten.In particular, in order to simplify assembly of the coupling housing 16 on the machine housing 14, the handheld power tool 10 also comprises at least one alignment element 44 (cf. in particular Figure 2 ). In the present case, the handheld power tool 10 comprises two alignment elements 44, in particular in the Figures 2 to 5 For the sake of clarity, only one of the alignment elements 44 is provided with a reference number. The alignment elements 44 are formed separately from the machine housing 14. In addition, the alignment elements 44 are formed separately from the coupling housing 16. The alignment elements 44 are made of metal. The alignment elements 44 are at least essentially identical to one another. The alignment elements 44 are also designed in the shape of a pin. The alignment elements 44 are designed at least essentially in the shape of a hollow cylinder. In the present case, the alignment elements 44 are designed as centering pins. The alignment elements 44 are provided at least to align the machine housing 14 and the coupling housing 16 relative to one another when the machine housing 14 and the coupling housing 16 are connected.

Im montierten Zustand sind die Ausrichtelemente 44 kraft- und/oder formschlüssig mit dem Maschinengehäuse 14 verbunden. Im vorliegenden Fall sind die Ausrichtelemente 44 im montierten Zustand mittels einer Klemmverbindung mit dem Maschinengehäuse 14 verbunden.In the assembled state, the alignment elements 44 are connected to the machine housing 14 in a force-fitting and / or form-fitting manner. In the present case, the alignment elements 44 are connected to the machine housing 14 by means of a clamp connection in the assembled state.

Zudem sind die Ausrichtelemente 44 im montierten Zustand kraft- und/oder formschlüssig mit dem Kopplungsgehäuse 16 verbunden. Im vorliegenden Fall sind die Ausrichtelemente 44 im montierten Zustand mittels einer Schraubverbindung mit dem Kopplungsgehäuse 16 verbunden. Dazu umfasst jedes der Ausrichtelemente 44 ein Innengewinde, welches zur Aufnahme eines Schraubverbindungselements 66 dient. Die Ausrichtelemente 44 sind somit zu einer Befestigung des Kopplungsgehäuses 16 an dem Maschinengehäuse 14 vorgesehen.In addition, the alignment elements 44 are non-positively and / or positively connected to the coupling housing 16 in the assembled state. In the present case are the alignment elements 44 are connected to the coupling housing 16 in the assembled state by means of a screw connection. For this purpose, each of the alignment elements 44 comprises an internal thread which is used to receive a screw connection element 66. The alignment elements 44 are thus provided for fastening the coupling housing 16 to the machine housing 14.

Ferner sind die Ausrichtelemente 44 im montierten Zustand derart ausgerichtet, dass eine jeweilige Haupterstreckungsrichtung der Ausrichtelemente 44 parallel zu der weiteren Trennrichtung 30 ist. Darüber hinaus sind die Ausrichtelemente 44 in die Trennrichtung 32 versetzt zueinander angeordnet. Alternativ könnte eine Handwerkzeugmaschine auch genau ein Ausrichtelement und/oder mehrere, insbesondere zumindest drei, zumindest vier und/oder zumindest fünf, Ausrichtelemente umfassen. Ferner könnte wenigstens ein Ausrichtelement auch aus Kunststoff bestehen. Zudem kann wenigstens ein Ausrichtelement einstückig mit einem Maschinengehäuse und/oder einem Kopplungsgehäuse ausgebildet sein. Zudem ist denkbar, wenigstens ein Ausrichtelement als Vollelement und/oder Vollprofil auszubilden.Furthermore, in the assembled state, the alignment elements 44 are aligned such that a respective main direction of extent of the alignment elements 44 is parallel to the further separation direction 30. In addition, the alignment elements 44 are arranged offset from one another in the separating direction 32. Alternatively, a handheld power tool could also include precisely one alignment element and / or several, in particular at least three, at least four and / or at least five alignment elements. Furthermore, at least one alignment element could also consist of plastic. In addition, at least one alignment element can be designed in one piece with a machine housing and / or a coupling housing. It is also conceivable to design at least one alignment element as a solid element and / or a solid profile.

Die Handwerkzeugmaschine 10 weist ferner eine Bearbeitungseinheit 50 auf (vgl. Figur 1). Die Bearbeitungseinheit 50 ist in dem Frontbereich der Handwerkzeugmaschine 10 angeordnet. Die Bearbeitungseinheit 50 ist in einem Frontbereich des Maschinengehäuses 14 angeordnet. Im vorliegenden Fall ist die Bearbeitungseinheit 50 zumindest teilweise innerhalb des Maschinengehäuses 14 angeordnet. Die Bearbeitungseinheit 50 umfasst zumindest eine Bearbeitungswerkzeugaufnahme, welche zu einer Aufnahme eines Bearbeitungswerkzeugs vorgesehen ist. Das Bearbeitungswerkzeug ist im vorliegenden Fall zu einer spanenden Bearbeitung von Werkstücken vorgesehen. Alternativ ist denkbar, dass eine Bearbeitungseinheit unmittelbar einem Bearbeitungswerkzeug entspricht.The handheld power tool 10 also has a processing unit 50 (cf. Figure 1 ). The processing unit 50 is arranged in the front region of the handheld power tool 10. The processing unit 50 is arranged in a front area of the machine housing 14. In the present case, the processing unit 50 is at least partially arranged within the machine housing 14. The machining unit 50 comprises at least one machining tool holder, which is provided for holding a machining tool. In the present case, the machining tool is intended for machining workpieces. Alternatively, it is conceivable that a machining unit corresponds directly to a machining tool.

Zum Antrieb und/oder Betrieb der Bearbeitungseinheit 50 umfasst die Handwerkzeugmaschine 10 eine Antriebseinheit 12. Die Antriebseinheit 12 ist innerhalb des Maschinengehäuses 14 angeordnet. Die Antriebseinheit 12 umfasst einen Motor 60, im vorliegenden Fall insbesondere einen Elektromotor. Die Antriebseinheit 12 umfasst ferner ein Getriebe 62, im vorliegenden Fall insbesondere ein Oszillationsgetriebe. Zudem steht die Antriebseinheit 12 in Wirkverbindung mit der Bearbeitungseinheit 50. Die Antriebseinheit 12 ist dazu vorgesehen, die Bearbeitungseinheit 50 oszillierend, insbesondere in einer hin und her Bewegung über einen definierten Winkelbereich, anzutreiben. Alternativ ist denkbar, einen Motor einer Antriebseinheit als Verbrennungsmotor und/oder Hybridmotor auszubilden. Auch könnte ein Getriebe grundsätzlich von einem Oszillationsgetriebe verschieden sein.To drive and / or operate the machining unit 50, the handheld power tool 10 includes a drive unit 12. The drive unit 12 is arranged within the machine housing 14. The drive unit 12 comprises a motor 60, in the present case in particular an electric motor. The drive unit 12 also includes a gear 62, in the present case in particular an oscillation gear. In addition, the drive unit 12 is in operative connection with the processing unit 50. The drive unit 12 is provided to drive the processing unit 50 in an oscillating manner, in particular in a back and forth movement over a defined angular range. Alternatively, it is conceivable to design a motor of a drive unit as an internal combustion engine and / or a hybrid engine. A transmission could also be fundamentally different from an oscillation transmission.

Die Handwerkzeugmaschine 10 umfasst zudem eine Elektronikeinheit 20. Die Elektronikeinheit 20 ist als elektrische und/oder elektronische Einheit ausgebildet. Im vorliegenden Fall ist die Elektronikeinheit 20 als Elektronikplatine ausgebildet. Die Elektronikeinheit 20 ist vollständig in dem Kopplungsgehäuse 16 angeordnet. Die Elektronikeinheit 20 ist als Steuerelektronik ausgebildet. Die Elektronikeinheit 20 ist im vorliegenden Fall als Steuerelektronik für die Energiespeichereinheit 18 ausgebildet und insbesondere zu einer Steuerung eines Betriebs und/oder einer Versorgung der Energiespeichereinheit 18 vorgesehen. Demnach weist die Elektronikeinheit 20 in zumindest einem Betriebszustand eine elektrische Verbindung mit der Energiespeichereinheit 18 auf. Alternativ oder zusätzlich könnte eine Elektronikeinheit jedoch auch als Steuerelektronik für eine Antriebseinheit und/oder als Auswerteelektronik ausgebildet sein.The handheld power tool 10 also includes an electronics unit 20. The electronics unit 20 is designed as an electrical and / or electronic unit. In the present case, the electronics unit 20 is designed as an electronics board. The electronics unit 20 is arranged completely in the coupling housing 16. The electronics unit 20 is designed as control electronics. In the present case, the electronics unit 20 is designed as control electronics for the energy storage unit 18 and is provided in particular to control an operation and / or a supply of the energy storage unit 18. Accordingly, the electronics unit 20 has an electrical connection to the energy storage unit 18 in at least one operating state. Alternatively or additionally, however, an electronics unit could also be designed as control electronics for a drive unit and / or as evaluation electronics.

Bei einem Betrieb der Antriebseinheit 12 werden nun, insbesondere aufgrund der Oszillationsbewegung der Bearbeitungseinheit 50 und/oder der Antriebseinheit 12, Vibrationen und/oder Schwingungen auf das Maschinengehäuse 14 übertragen. Insbesondere um eine Übertragung dieser Vibrationen und/oder Schwingungen auf das Kopplungsgehäuse 16 zumindest teilweise abzuschwächen, wodurch die Elektronikeinheit 20 und die Energiespeichereinheit 18 geschützt werden, umfasst die Handwerkzeugmaschine 10 eine Dämpfungseinheit 22 (vgl. insbesondere Figur 2). Die Dämpfungseinheit 22 ist zwischen dem Maschinengehäuse 14 und dem Kopplungsgehäuse 16 angeordnet. Die Dämpfungseinheit 22 ist in dem Verbindungsbereich 24 angeordnet. Die Dämpfungseinheit 22 kontaktiert das Maschinengehäuse 14 und das Kopplungsgehäuse 16 unmittelbar. Die Dämpfungseinheit 22 ist dazu vorgesehen, bei einem Betrieb der Antriebseinheit 12 eine Übertragung von Vibrationen und/oder Schwingungen von dem Maschinengehäuse 14 auf das Kopplungsgehäuse 16 zumindest teilweise zu dämpfen.When the drive unit 12 is in operation, vibrations and / or oscillations are now transmitted to the machine housing 14, in particular due to the oscillating movement of the machining unit 50 and / or the drive unit 12. In particular, in order to at least partially weaken a transmission of these vibrations and / or oscillations to the coupling housing 16, whereby the electronics unit 20 and the energy storage unit 18 are protected, the handheld power tool 10 comprises a damping unit 22 (cf. in particular Figure 2 ). The damping unit 22 is arranged between the machine housing 14 and the coupling housing 16. The damping unit 22 is arranged in the connection area 24. The damping unit 22 makes direct contact with the machine housing 14 and the coupling housing 16. The damping unit 22 is provided to at least partially dampen a transmission of vibrations and / or oscillations from the machine housing 14 to the coupling housing 16 when the drive unit 12 is in operation.

Dazu umfasst die Dämpfungseinheit 22 zumindest ein Dämpfungselement 42. Im vorliegenden Fall umfasst die Dämpfungseinheit 22 vier Dämpfungselemente 42, wobei insbesondere in den Figuren 2 bis 5 der Übersichtlichkeit halber lediglich eines der Dämpfungselemente 42 mit Bezugszeichen versehen ist. Die Dämpfungselemente 42 sind zumindest im Wesentlichen baugleich. Die Dämpfungselemente 42 sind zylinderförmig, im vorliegenden Fall insbesondere kreiszylinderförmig, ausgebildet. Die Dämpfungselemente 42 sind ferner hohlzylinderförmig ausgebildet.For this purpose, the damping unit 22 comprises at least one damping element 42. In the present case, the damping unit 22 comprises four damping elements 42, in particular in the Figures 2 to 5 for the sake of clarity, only one of the damping elements 42 is provided with reference symbols. The damping elements 42 are at least essentially identical. The damping elements 42 are cylindrical, in the present case in particular circular cylindrical. The damping elements 42 are also designed as a hollow cylinder.

Die Dämpfungselemente 42 sind darüber hinaus flexibel ausgebildet. Die Dämpfungselemente 42 sind verformbar ausgebildet. Die Dämpfungselemente 42 sind elastisch ausgebildet und bestehen vollständig aus einem elastischen Material. Die Dämpfungselemente 42 bestehen aus einem dämpfungsfähigen Material. Im vorliegenden Fall bestehen die Dämpfungselemente 42 aus Gummi.The damping elements 42 are also designed to be flexible. The damping elements 42 are designed to be deformable. The damping elements 42 are elastic and consist entirely of an elastic material. The damping elements 42 consist of a damping material. In the present case, the damping elements 42 are made of rubber.

In einem montierten Zustand kontaktieren die Dämpfungselemente 42 das Maschinengehäuse 14, das Kopplungsgehäuse 16 und zumindest eines der Ausrichtelemente 44 unmittelbar. Dabei sind jeweils zwei der Dämpfungselemente 42 bezüglich der weiteren Trennrichtung 30 auf gegenüberliegenden Seiten der Handwerkzeugmaschine 10 angeordnet. Die Dämpfungselemente 42 sind vollständig innerhalb des Kopplungsgehäuses 16 angeordnet. Die Dämpfungselemente 42 sind zwischen einer Innenseite des Kopplungsgehäuses 16 und einer Außenseite des Maschinengehäuses 14 angeordnet, insbesondere eingeklemmt. Im vorliegenden Fall weist das Maschinengehäuse 14 dabei mehrere, im vorliegenden Fall insbesondere vier, zu den Dämpfungselementen 42 korrespondierende Aufnahmevertiefungen 64 auf, wobei im montierten Zustand in jeder der Aufnahmevertiefungen 64 eines der Dämpfungselemente 42 angeordnet ist (vgl. insbesondere Figur 3). Zudem sind jedem der Ausrichtelemente 44 zwei der Dämpfungselemente 42 zugeordnet. Dabei umgreifen die Dämpfungselemente 42 das jeweilige Ausrichtelement 44 vollständig.In an assembled state, the damping elements 42 contact the machine housing 14, the coupling housing 16 and at least one of the alignment elements 44 directly. Two of the damping elements 42 are in each case arranged on opposite sides of the handheld power tool 10 with respect to the further separation direction 30. The damping elements 42 are arranged completely within the coupling housing 16. The damping elements 42 are arranged, in particular clamped, between an inside of the coupling housing 16 and an outside of the machine housing 14. In the present case, the machine housing 14 has several, in the present case in particular four, receiving recesses 64 corresponding to the damping elements 42, one of the damping elements 42 being arranged in each of the receiving recesses 64 in the assembled state (cf. in particular Figure 3 ). In addition, two of the damping elements 42 are assigned to each of the alignment elements 44. The damping elements 42 completely encompass the respective alignment element 44.

Im Folgenden wird nun unter Verweis auf die Figuren 4 und 5 eine Anordnung eines Dämpfungselements 42 der Dämpfungselemente 42 näher beschrieben, wobei die folgende Beschreibung, insbesondere aufgrund der zumindest im Wesentlichen baugleichen Bauweise der Dämpfungselemente 42, auch auf die anderen Dämpfungselemente 42 übernommen werden kann.In the following, with reference to the Figures 4 and 5 an arrangement of a damping element 42 of the damping elements 42 is described in more detail, the following description, in particular due to the at least substantially structurally identical design of the damping elements 42 can also be applied to the other damping elements 42.

Das Dämpfungselement 42 ist in einer der Aufnahmevertiefungen 64 des Maschinengehäuses 14 angeordnet. Dabei kontaktiert eine erste Deckfläche 68 des Dämpfungselements 42 das Maschinengehäuse 14. Zudem kontaktiert eine Außenseitenfläche 70 des Dämpfungselements 42 das Maschinengehäuse 14. Im vorliegenden Fall kontaktiert die Außenseitenfläche 70 des Dämpfungselements 42 das Maschinengehäuse 14 zumindest über einen Teil einer gesamten Erstreckung des Dämpfungselements 42.The damping element 42 is arranged in one of the receiving recesses 64 of the machine housing 14. A first cover surface 68 of the damping element 42 contacts the machine housing 14. In addition, an outer side surface 70 of the damping element 42 contacts the machine housing 14. In the present case, the outer side surface 70 of the damping element 42 contacts the machine housing 14 at least over part of an entire extent of the damping element 42.

Ferner umgreift das Dämpfungselement 42 eines der Ausrichtelemente 44 vollständig. Dabei kontaktiert eine Innenseitenfläche 72 des Dämpfungselements 42 das Ausrichtelement 44. Im vorliegenden Fall kontaktiert die Innenseitenfläche 72 des Dämpfungselements 42 das Ausrichtelement 44 über eine gesamte Erstreckung des Dämpfungselements 42.Furthermore, the damping element 42 completely encompasses one of the alignment elements 44. In this case, an inner side surface 72 of the damping element 42 contacts the alignment element 44. In the present case, the inner side surface 72 of the damping element 42 contacts the alignment element 44 over an entire extent of the damping element 42.

Darüber hinaus kontaktiert eine, insbesondere der ersten Deckfläche 68 gegenüberliegende, zweite Deckfläche 74 des Dämpfungselements 42 das Kopplungsgehäuse 16.In addition, a second cover surface 74 of the damping element 42 opposite, in particular, the first cover surface 68 makes contact with the coupling housing 16.

Alternativ könnte eine Dämpfungseinheit auch eine andere Anzahl an Dämpfungselementen aufweisen, wie beispielsweise genau ein Dämpfungselement und/oder zwei Dämpfungselemente und/oder zumindest sechs Dämpfungselemente. Auch könnte wenigstens ein Dämpfungselement eine von einem Zylinder abweichende Form aufweisen und beispielsweise kegelstumpfförmig ausgebildet sein. Ferner könnte wenigstens ein Dämpfungselement prinzipiell auch aus Silikon und/oder einem Thermoplasten bestehen.Alternatively, a damping unit could also have a different number of damping elements, such as precisely one damping element and / or two damping elements and / or at least six damping elements.
