Es wird vorgeschlagen, dass die Zwischenwelle und die Zahn- rademheit in axialer Richtung relativ zueinander bewegbar sind, wodurch eine kompakte Schaltanordnung mit einem konstruktiv einfachen Schaltmechanismus erreicht werden kann. Zur Erzeugung einer relativen Bewegung in axialer Richtung zwischen der Zahnradeinheit und der Zwischenwelle kann dabei die Zahnradeinheit und/oder besonders vorteilhaft die Zwischenwelle verschoben werden, so dass ein besonders leichtes Verschieben für einen Bediener der Schaltvorrichtung bzw. der Handwerkzeugmaschine aufgrund einer geringen Trägheit der zu verschiebenden Masse erreicht werden kann. Vorteil- hafterweise ist die Zahnradeinheit in axialer Richtung ortsfest in Bezug auf ein Gehäuse der Handwerkzeugmaschine und/oder ein Abtriebsmittel, wie insbesondere ein Hammer- röhr, angeordnet. In diesem Zusammenhang soll unter einerThe invention relates to a hand tool, in particular a hammer drill, with a switching device having an axially displaceable intermediate shaft and arranged on the intermediate shaft gear unit and which is provided for switching between different types of drive and / or drive speeds of a tool. It is proposed that the intermediate shaft and the toothed wheel unit can be moved relative to each other in the axial direction, whereby a compact shifting arrangement with a structurally simple shifting mechanism can be achieved. To generate a relative movement in the axial direction between the gear unit and the intermediate shaft while the gear unit and / or particularly advantageously the intermediate shaft can be moved, so that a particularly easy shifting for an operator of the switching device or the power tool due to a low inertia to be moved Mass can be achieved. Advantageously, the gear unit is fixed in the axial direction with respect to a housing of the power tool and / or a driven means, in particular a hammer tube. In this context, under a
„axialen Richtung" eine Richtung verstanden werden, die sich vorzugsweise entlang einer Haupterstreckungsπchtung, wie insbesondere einer Lange, der Zwischenwelle erstreckt."Axial direction" is understood to mean a direction which preferably extends along a main extension direction, in particular a length, of the intermediate shaft.
Des Weiteren wird vorgeschlagen, dass die Zahnradeinheit zumindest zwei unabhängig voneinander drehbare Zahnrader aufweist, wodurch vorteilhaft unterschiedliche Antriebsge¬ schwindigkeiten für ein sich drehendes Abtriebsmittel zur Erzeugung einer drehenden Arbeitsbewegung eines Werkzeugs erreicht werden können. Vorzugsweise sind die Zahnrader der Zahnradeinheit mit unterschiedlichen Arbeitsdurchmessern bzw. mit unterschiedlichen Übersetzungsverhältnissen versehen . Eine konstruktiv einfache Übertragung eines Antriebsmoments auf das Zahnrad und/oder auf die Zahnradeinheit kann vorteilhaft erreicht werden, wenn zumindest eines der Zahnrader zumindest ein Schaltmittel aufweist, das an einer radial nach innen gerichteten Oberflache angeordnet ist. Besonders einfach kann dies verwirklicht werden, wenn zudem die Zwi- schenwelle ein zu dem Schaltmittel des Zahnrads korrespondierendes Schaltmittel aufweist.It is further proposed that the gear unit has at least two independently rotatable COGS, thereby advantageously different Antriebsge ¬ speeds for a rotating drive means for generating a rotating working movement of a tool can be achieved. Preferably, the gear wheels of the gear unit are provided with different working diameters or with different gear ratios. A structurally simple transmission of a drive torque to the gear wheel and / or to the gear unit can be advantageously achieved if at least one of the gear wheels has at least one switching means which is arranged on a radially inwardly directed surface. This can be achieved particularly easily if, in addition, the has a shaft corresponding to the switching means of the gear switching means.
In einer vorteilhaften Weiterbildung der Erfindung wird vor- geschlagen, dass das Schaltmittel verdrehfest und in axialer Richtung ortsfest auf der Zwischenwelle angeordnet ist. Hierdurch kann eine besonders kompakte Schaltvorrichtung bei einer Übertragung eines Antriebsmoments erreicht werden, insbesondere wenn das Schaltmittel direkt auf der Zwischen- welle angeordnet ist, und damit kann auf zusätzliche kop¬ pelnde und/oder verbindende Bauteile, die zwischen der Zwischenwelle und dem Schaltmittel angeordnet sind, verzichtet werden. Zudem kann eine konstruktive Übertragung eines Antriebsmoments mittels eines Verschiebens der Zwischenwelle auf die unterschiedlichen Zahnrader der Zahnradeinheit erreicht werden.In an advantageous development of the invention, it is proposed that the switching means is arranged rotationally fixed and fixed in the axial direction on the intermediate shaft. In this way, a particularly compact switching device can be achieved in a transmission of a drive torque, in particular if the switching means is arranged directly on the intermediate shaft, and thus can on additional kop ¬ pelnde and / or connecting components, which are arranged between the intermediate shaft and the switching means , be waived. In addition, a constructive transmission of a drive torque can be achieved by means of a displacement of the intermediate shaft on the different gears of the gear unit.
Eine vorteilhafte Übertragung eines Antriebsmoments im Betrieb der Handwerkzeugmaschine auf die Zwischenwelle unter Beibehaltung einer kompakten Bauweise der Schaltvorrichtung kann erreicht werden, wenn die Schaltvorrichtung ein Kopplungselement aufweist, über das die Zwischenwelle an ein An- tπebsmomentubertragungsmittel koppelbar ist. Das Antπebs- momentubertragungsmittel kann von einer Antriebseinheit bzw. einer Ankerwelle der Antriebseinheit oder besonders vorteilhaft von einer Zwischenhulse gebildet sein.An advantageous transmission of a drive torque during operation of the handheld power tool to the intermediate shaft while maintaining a compact design of the switching device can be achieved if the switching device has a coupling element, via which the intermediate shaft can be coupled to a tπebsmomentubertragungsmittel. The anti-momentum transmission means may be formed by a drive unit or an armature shaft of the drive unit or particularly advantageously by an intermediate sleeve.
Eine besonders kompakte und kostengünstige Schaltvorrichtung kann erreicht werden, wenn die Schaltvorrichtung eine Schlagwerksanordnung aufweist, die mittels eines Verschie- bens der Zwischenwelle m axialer Richtung an- oder ausschaltbar ist. Die Zwischenwelle kann dabei direkt oder indirekt über ein zwischengeschaltetes Schaltelement an die Schlagwerksanordnung koppeln. Weist die Schaltvorrichtung zudem eine variable Sperrfunktion auf, die mittels eines Verschiebens der Zwischenwelle in axialer Richtung schaltbar ist, kann zudem ein konstruktiv einfaches Schalten unterschiedlicher Antriebsarten mittels Verschieben eines Bauteils, insbesondere der Zwischenwelle, innerhalb der Schalt- Vorrichtung realisiert werden.A particularly compact and inexpensive switching device can be achieved if the switching device has a striking mechanism arrangement which can be switched on or off by means of a displacement of the intermediate shaft m in the axial direction.

Does the switching device also has a variable lock function, which by means of a Moving the intermediate shaft can be switched in the axial direction, also a structurally simple switching different types of drives can be realized by moving a component, in particular the intermediate shaft, within the switching device.
In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, dass die Schaltvorrichtung ein einzelnes Bedien- element aufweist, das zum Schalten zwischen unterschiedli- chen Antriebsarten und Antriebsgeschwindigkeiten vorgesehen ist. Hierdurch kann mittels einer einfachen Schaltlogik der Schaltvorrichtung ein hoher Bedienkomfort für einen Bediener einer Handwerkzeugmaschine mit der Schaltvorrichtung erreicht werden.In a further embodiment of the invention it is proposed that the switching device has a single operating element, which is provided for switching between different drive types and drive speeds.

In Figur 2 ist ein reiner Meißelbetrieb der Handwerkzeugma- schine 10 dargestellt. Das Bedienelement 36 befindet sich m der Meißelbetπebsposition (Figur Ib) und die Zwischenwelle 14 befindet sich in einer abtπebseitigen Endstellung, in der das Kopplungselement 60 der Zwischenwelle 14 beabstandet zum Kopplungselement 58 der Zahnhulse angeordnet ist und eine Übertragung eines Antriebsmoments von der Zahnhulse auf die Zwischenwelle 14 unterbrochen ist. Em auf der Zwischenwelle 14 gelagertes Arretierelement 82, das in Richtung 98 nach der Zahnradeinheit 16 angeordnet ist, ist dabei m einer Sperrposition mit dem Schaltmittel 28 der Zwischenwelle 14. Das Arretierelement 82 weist dabei eine nicht naher dargestellte Innenverzahnung auf, die m der Sperrposition m Eingriff mit dem Schaltmittel 28 der Zwischenwelle 14 ist. Zu einer Arretierung ist das Arretierelement 82 ortsfest ge¬ genüber dem Gehäuse 46 der Handwerkzeugmaschine 10 arretiert (Figur 2) . Die Zahnhulse ist mittels einer Federkraft des Federelements 48 des Antriebslagers 44, die auf die Zahnhulse in axiale Richtung 98 wirkt, in einer der Schlagwerksan- Ordnung 34 zugewandten Endposition. Dabei greift das Kopplungselement 70 der Zahnhulse in das Kopplungselement 72 der Schlagwerksanordnung 34. Mittels des Kopplungselements 70 übertragt die Zahnhulse ein Antriebsmoment auf die Taumel- hulse 96 der Schlagwerksanordnung 34 zur Generierung eines Schlagimpulses für das m der Werkzeugaufnahme 42 befindliche Werkzeug.FIG. 2 shows a pure bit operation of the hand-held power tool 10. The operating element 36 is located in the chisel bed position (FIG. 1b) and the intermediate shaft 14 is located in an abtπebseitigen end position in which the coupling element 60 of the intermediate shaft 14 spaced is arranged to the coupling element 58 of the Zahnhulse and a transmission of a drive torque from the Zahnhulse is interrupted on the intermediate shaft 14. Em on the intermediate shaft 14 mounted locking member 82 which is arranged in the direction 98 after the gear unit 16, while m is a blocking position with the switching means 28 of the intermediate shaft 14. The locking member 82 has a not shown closer internal teeth, the m of the blocking position m Engagement with the switching means 28 of the intermediate shaft 14 is. To a detent, the locking element 82 is fixed ge ¬ genüber the housing 46 of the power tool 10 is locked (Figure 2). The Zahnhulse is by means of a spring force of the spring element 48 of the drive bearing 44, which acts on the Zahnhulse in the axial direction 98, in a Schlagwerksan- order 34 facing the end position. In this case, the coupling element 70 engages the Zahnhulse in the coupling element 72 of the hammer mechanism 34. By means of the coupling element 70 Zahnhulse transmits a drive torque on the Taumel- hulse 96 of the hammer mechanism assembly 34 for generating a shock pulse for the m of the tool holder 42 located tool.
Wird das Bedienelement 36 von einem Bediener um ca. 45° in Richtung 90 gedreht und auf eine Betriebsposition mit einer variablen Sperrfunktion eingestellt, wird dabei die Zwischenwelle 14 in axiale Richtung 18 verschoben (Figuren Ic und 3) . Durch das Verschieben der Zwischenwelle 14 in axiale Richtung 18 wird eine Sperrposition zwischen den Arretier- elementen 82 bzw. der Innenverzahnung des Arretierelements 82 und dem Schaltmittel 28 der Zwischenwelle 14 aufgehoben und das Werkzeug m der Werkzeugaufnahme 42, wie beispielsweise ein Meißelwerkzeug, kann von einem Bediener gedreht bzw. positioniert werden. Das Kopplungselement 60 der Zwi- schenwelle 14 ist weiterhin beabstandet zum Kopplungselement 58 der Zahnhulse angeordnet.If the operating element 36 is rotated by an operator by approximately 45 ° in the direction 90 and set to an operating position with a variable blocking function, the intermediate shaft 14 is displaced in the axial direction 18 (FIGS. 1c and 3). By moving the intermediate shaft 14 in the axial direction 18, a locking position between the Arretier- elements 82 and the internal teeth of the locking member 82 and the switching means 28 of the intermediate shaft 14 is repealed and the tool m of the tool holder 42, such as a chisel tool, from a Operator rotated or positioned. The coupling element 60 of the intermediate The shaft 14 is further spaced from the coupling element 58 of the Zahnhulse arranged.
Wird das Bedienelement 36 von dem Bediener um ca. weitere 45° in Richtung 90 gedreht und auf eine Betriebsposition mit einem Schlagbohrbetrieb eingestellt, wird die Zwischenwelle 14 weiter in axiale Richtung 18 verschoben (Figuren Id und 4) . Das Kopplungselement 60 der Zwischenwelle 14 greift in das Kopplungselement 58 der Zahnhulse und im Betrieb der Handwerkzeugmaschine 10 wird ein Antriebsmoment von derIf the operating element 36 is rotated by the operator by approximately another 45 ° in the direction 90 and set to an operating position with a percussion drilling operation, the intermediate shaft 14 is displaced further in the axial direction 18 (FIGS. Id and 4). The coupling element 60 of the intermediate shaft 14 engages in the coupling element 58 of the Zahnhulse and in operation of the power tool 10 is a drive torque of the
Zahnhulse auf die Zwischenwelle 14 übertragen. Das Schaltmittel 28 der Zwischenwelle 14 ist dabei in Eingriff mit dem Schaltmittel 24 des ersten Zahnrads 20 der Zahnradeinheit 16. Von der Zwischenwelle 14 wird das Antriebsmoment auf die Zahnradeinheit 16 bzw. auf das Zahnrad 20 übertragen und damit das von dem Hammerrohr gebildete Abtriebsmittel 76, das ein Drehmoment auf das m der Werkzeugaufnahme 42 befindliche Werkzeug übertragt, angetrieben. Weiterhin wird im Betrieb der Handwerkzeugmaschine 10 ein Antriebsmoment von der Zahnhulse über die Kopplungselemente 70, 72 auf die Schlagwerksanordnung 34 übertragen. Das Werkzeug fuhrt im Betrieb der Handwerkzeugmaschine 10 eine drehende und schla¬ gende Arbeitsbewegung aus.Zahnhulse transmitted to the intermediate shaft 14. The switching means 28 of the intermediate shaft 14 is in engagement with the switching means 24 of the first gear 20 of the gear unit 16. From the intermediate shaft 14, the drive torque is transmitted to the gear unit 16 and the gear 20 and thus the driven means 76 formed by the hammer tube, which transmits a torque to the m of the tool holder 42 located tool, driven. Furthermore, a drive torque is transmitted from the Zahnhulse via the coupling elements 70, 72 on the percussion mechanism assembly 34 during operation of the power tool 10. The tool carries out a rotating and schla ¬ ing working movement during operation of the power tool 10.
Wird das Bedienelement 36 von dem Bediener um ca. weitereIf the control element 36 by the operator by about another
45° in Richtung 90 gedreht und auf eine Betriebsposition mit einem reinen Bohrbetrieb mit einer langsamen Geschwindigkeit eingestellt, wird die Zwischenwelle 14 weiter in axiale Richtung 18 verschoben (Figuren Ie und 5) . Mittels der Ver- Schiebung der Zwischenwelle 14 wird die Zahnhulse gegen die Federkraft des Federelements 48 ebenfalls in axiale Richtung 18 bewegt. Dabei bewegt sich das Kopplungselement 70 der Zahnhulse aus dem Kopplungselement 72 der Schlagwerksanord¬ nung 34 heraus, so dass diese beabstandet zueinander ange- ordnet sind und eine Übertragung des Antriebsmoments auf die Schlagwerksanordnung 34 im Betrieb unterbrochen ist. Parallel hierzu wird auch das Schaltmittel 28 der Zwischenwelle 14 in axiale Richtung 18 mit der Zwischenwelle 14 verscho- ben, wobei das Schaltmittel 28 weiterhin in Eingriff mit dem Schaltmittel 24 des Zahnrads 20 der Zahnrademheit 16 ist, so dass mittels des Zahnrads 20 eine gegenüber dem Schlagbohrbetrieb gleiche Antriebsgeschwindigkeit auf das Abtriebsmittel 76 übertragen wird. Das m der Werkzeugaufnahme 42 befindliche Werkzeug fuhrt eine ausschließlich drehende Bewegung im Betrieb der Handwerkzeugmaschine 10 aus.Turned 45 ° in the direction 90 and set to an operating position with a pure drilling operation at a slow speed, the intermediate shaft 14 is further displaced in the axial direction 18 (Figures Ie and 5). By means of the displacement of the intermediate shaft 14, the toothed sleeve is also moved in the axial direction 18 against the spring force of the spring element 48. In this case, the coupling element 70 of the Zahnhulse from the coupling element 72 of the Schlagwerksanord ¬ voltage 34 is moved out so that these mutually spaced reasonable are orders and transmission of the drive torque to the percussion device 34 is interrupted during operation. In parallel with this, the switching means 28 of the intermediate shaft 14 is also displaced in the axial direction 18 with the intermediate shaft 14, the switching means 28 furthermore being in engagement with the switching means 24 of the gearwheel 20 of the gearwheel unit 16, so that by means of the gearwheel 20 a relation to FIG Schlagbohrbetrieb same drive speed is transmitted to the output means 76.

Wird das Bedienelement 36 von dem Bediener um ca. weitere 45° in Richtung 90 gedreht und auf eine Betriebsposition mit einem reinen Bohrbetrieb mit einer schnellen Geschwindigkeit eingestellt, wird die Zwischenwelle 14 weiter in axiale Richtung 18 in eine antπebsseitige Endposition verschoben (Figuren If und 6) . Mittels der Verschiebung der Zwischenwelle 14 wird die Zahnhulse weiter gegen die Federkraft des Federelements 48 bewegt und das Kopplungselement 60 derIf the operating element 36 is rotated by the operator by approximately another 45 ° in the direction 90 and adjusted to an operating position with a pure drilling operation at a fast speed, the intermediate shaft 14 is further displaced in the axial direction 18 in an antπebsseitige end position (Figures If and 6 ). By means of the displacement of the intermediate shaft 14, the Zahnhulse is further moved against the spring force of the spring element 48 and the coupling element 60 of
Zahnhulse ist zum Kopplungselement 58 der Schlagwerksanordnung 34 weiterhin beabstandet angeordnet. Parallel dazu ver¬ schiebt sich das Schaltmittel 28 zusammen mit der Zwischenwelle 14 ebenfalls in axiale Richtung 18 und das von der Mitnahmeverzahnung gebildete Schaltmittel 28 wird mittels der Zwischenwelle 14 aus dem Schaltmittel 24 des Zahnrads 20 heraus m das Schaltmittel 26 des Zahnrads 22 der Zahnrademheit 16 geschoben. Aufgrund des größeren Arbeitsdurchmessers 80 des Zahnrads 22 bezüglich des Zahnrads 20 ist im Be- trieb der Handwerkzeugmaschine 10 eine höhere Antriebsgeschwindigkeit auf das von dem Hammerrohr gebildete Abtriebsmittel 76 übertragbar und das in der Werkzeugaufnahme 42 befindliche Werkzeug fuhrt weiterhin eine drehende Bewegung aus . Zahnhulse is further spaced from the coupling element 58 of the percussion mechanism 34. In parallel, ver ¬ the switching means 28 also moves together with the intermediate shaft 14 in the axial direction 18 and the switching means 28 formed by the driving teeth is by means of the intermediate shaft 14 from the switching means 24 of the gear 20 out m the switching means 26 of the gear 22 of the Zahnrademheit 16 pushed. Due to the larger working diameter 80 of the toothed wheel 22 relative to the toothed wheel 20, a higher driving speed can be transmitted to the output means 76 formed by the hammer tube during operation of the hand tool 10, and the tool located in the tool holder 42 continues to perform a rotating movement.
