Description

Die vorliegende Erfindung betrifft eine angetriebene Werkzeugmaschine, insbesondere einen Winkelschleifer oder einen Geradschleifer, umfassend eine Antriebseinheit mit einem als Würfelschalter bzw. Druckschalter ausgebildeten Antriebsschalter zum Ein- und Ausschalten der Antriebseinheit, ein Gehäuse, in dem die Antriebseinheit wenigstens teilweise aufgenommen ist, sowie einen Betätigungsmechanismus zum Betätigen des Antriebsschalters.The present invention relates to a driven machine tool, in particular an angle grinder or a straight grinder, comprising a drive unit with a drive switch designed as a cube switch or pressure switch for switching the drive unit on and off, a housing in which the drive unit is at least partially accommodated, and an actuating mechanism to operate the drive switch.

Eine solche angetriebene Werkzeugmaschine ist beispielsweise aus der deutschen Offenlegungsschrift DE 10 2007 025 009 A1 bekannt. Zum Betätigen des Antriebsschalters umfasst der aus dem Stand der Technik bekannte Betätigungsmechanismus einen Schaltschieber bzw. eine Schaltstange, die mit einem von außen für den Anwender zugänglichen Schaltknopf bzw. Betätigungsabschnitt betätigt wird und die relativ zu dem Gehäuse verschoben wird. Infolge einer Verschiebung des Schaltschiebers bzw. der Schaltstange drückt ein rechtwinklig zu der Längsachse der Schaltstange abgewinkelter Abschnitt der Schaltstange auf den Antriebsschalter, wodurch dieser verlagert und aktiviert wird.Such a driven machine tool is, for example, from the German Offenlegungsschrift DE 10 2007 025 009 A1 known. To actuate the drive switch, the actuating mechanism known from the prior art comprises a switching slide or a switching rod which is actuated with a switching button or actuating section which is accessible to the user from the outside and which is displaced relative to the housing. As a result of a displacement of the shift slide or the shift rod, a section of the shift rod which is angled at right angles to the longitudinal axis of the shift rod presses on the drive switch, as a result of which the latter is displaced and activated.

Eine solche abgewinkelte Schaltstange hat den Vorteil, einen besonders einfachen Betätigungsmechanismus bereitzustellen. Als Nachteil hat sich jedoch in der Praxis die Verwendung einer derartigen abgewinkelten Schaltstange in Geräten erwiesen, die in einer Arbeitsumgebung verwendet werden, bei der ein hoher Anteil von Staubpartikeln in der Umgebungsluft vorliegt, welche gegebenenfalls in das Gehäuse eindringen können. Die Staubpartikel können sich nämlich im Bereich des Betätigungsmechanismus ansammeln, wodurch die Schaltstange möglicherweise in ihrer Verschiebebewegung behindert und dadurch schwergängig zu verschieben wird. Dies ist insbesondere auch bedingt durch vergleichsweise hohe Querkräfte, die über den abgewinkelten Abschnitt der Schaltstange aufgebracht werden müssen, damit der Antriebsschalter zum Einschalten verlagert werden kann.Such an angled shift rod has the advantage of providing a particularly simple actuation mechanism. In practice, however, the use of such an angled switching rod in devices that are used in a working environment in which there is a high proportion of dust particles in the ambient air, which can possibly penetrate into the housing, has proven to be a disadvantage in practice. This is because the dust particles can accumulate in the area of the actuating mechanism, as a result of which the shift rod may be impeded in its shifting movement and thus become difficult to shift. This is also due in particular to comparatively high transverse forces that have to be applied via the angled section of the switching rod so that the drive switch can be shifted to switch on.

Es ist ferner aus der deutschen Patentschrift DE 35 40 652 C2 im Zusammenhang mit einem elektrischen Schraubendreher bekannt, einen Betätigungsmechanismus vorzusehen, bei dem durch Andrücken des Werkzeugs in eine Richtung eine Schaltstange in die gleiche Richtung bewegt wird, welche wiederum einen Doppelhebel verschwenkt, um einen Stift gegen die Vorspannkraft einer Druckfeder zu verschieben und hierdurch einen elektrischen Schalter zu schließen. Bei dieser Ausgestaltung kann auf einen Betätigungsabschnitt, bei dem der Anwender die Verschiebung der Schaltstange einleitet, verzichtet werden.It is also from the German patent specification DE 35 40 652 C2 known in connection with an electric screwdriver to provide an actuating mechanism in which pressing the tool in one direction moves a switching rod in the same direction, which in turn pivots a double lever to move a pin against the biasing force of a compression spring and thereby an electric switch to close. In this configuration, an actuation section, in which the user initiates the shifting of the shift rod, can be dispensed with.

Aus der Offenlegungsschrift DE 10 2005 021 731 A1 ist ein Elektrowerkzeug mit einem in einem Gehäuse angeordneten Gerätekörper und einem Handgriff bekannt, wobei in dem Handgriff ein Schalter angeordnet ist. Dieser Schalter soll indirekt mit einem im Gerätekörper angeordneten Schaltelement zum Betätigen eines elektrischen Ein-Ausschalters verbunden sein. Hierzu ist ein Bowdenzug vorgesehen. Das hebelförmige Schaltelement weist einen oberen und einen unteren Hebelarm auf und ist um einen Drehpunkt schwenkbar gelagert, wobei der Bowdenzug mit einem Ende mit dem unteren Hebelarm des Schalters verbunden ist. Zum Schalten ist eine Schaltklinke vorgesehen, die mit dem anderen Ende des Bowdenzugs verbunden ist und bei einer Schaltbewegung translatorisch verschiebbar ist.From the disclosure document DE 10 2005 021 731 A1 discloses a power tool having a device body arranged in a housing and a handle, with a switch being arranged in the handle. This switch should be connected indirectly to a switching element arranged in the device body for actuating an electrical on/off switch. A Bowden cable is provided for this purpose. The lever-shaped switching element has an upper and a lower lever arm and is mounted pivotably about a pivot point, with one end of the Bowden cable being connected to the lower lever arm of the switch. A pawl is provided for switching, which is connected to the other end of the Bowden cable and can be displaced in a translatory manner during a switching movement.

Aus der Gebrauchsmusterschrift DE 20 2011 108 753 U1 ist ferner ein schwenkbarer Bedienhebel zur Bedienung eines Schalters bekannt, der um einen Lagerpunkt verschwenkt werden kann und einen damit gekoppelten Zwischenhebel mitverschwenkt, welcher den Schalter betätigt.From the utility model specification DE 20 2011 108 753 U1 a pivotable operating lever for operating a switch is also known, which can be pivoted about a bearing point and also pivots an intermediate lever coupled thereto, which actuates the switch.

Aus der WO 2005/062322 A1 , die die Basis für den Oberbegriff des Anspruchs 1 bildet, ist ferner eine Elektrowerkzeugmaschine mit einer geräteseitig entfernbaren Versorgungseinheit zur elektrischen Spannungsversorgung bekannt, die einen zumindest mittelbar betätigbaren Schalter zum Einschalten und Ausschalten einer Antriebsmaschine aufweist. Zum Entkoppeln des Schalters und eines den Schalter zumindest teilweise betätigenden Schaltmittels ist eine Entkopplungsvorrichtung vorgesehen.From the WO 2005/062322 A1 , which forms the basis for the preamble of claim 1, is also a power tool with a device side removable supply unit for electrical voltage supply is known, which has an at least indirectly operable switch for switching on and off a drive motor. To decouple the switch and a switching means that at least partially actuates the switch, a decoupling device is provided.

Schließlich offenbart die Offenlegungsschrift DE 32 36 713 A1 eine Schaltvorrichtung mit einem schiebe- und kippbar ausgebildeten Schaltorgan.Finally, the disclosure document discloses DE 32 36 713 A1 a switching device with a shiftable and tiltable switching element.

Eine Aufgabe der vorliegenden Erfindung besteht darin, den bekannten Mechanismus mit einer abgewinkelten Schaltstange in der Weise weiter zu entwickeln, dass auch in einer Arbeitsumgebung mit hohem Staubaufkommen ein sicheres Ein- und Ausschalten der Werkzeugmaschine gewährleistet ist.One object of the present invention is to further develop the known mechanism with an angled switching rod in such a way that safe switching on and off of the machine tool is ensured even in a working environment with a high level of dust.

Hierzu schlägt die vorliegende Erfindung eine angetriebene Werkzeugmaschine, insbesondere einen Winkelschleifer oder einen Geradschleifer, mit den Merkmalen des Anspruchs 1 vor. Demgemäß weist der Betätigungsmechanismus eine entlang der Längsachse des Gehäuses verschiebbare Schaltstange auf, die mit einem Betätigungsabschnitt eine Ausnehmung des Gehäuses durchragt, sowie einen Schalthebel, der in einem Lagerpunkt schwenkbar gelagert ist und wenigstens einen Hebelarm aufweist. Die Schaltstange ist ferner mit dem wenigstens einen Hebelarm erfindungsgemäß gekoppelt und vermag diesen infolge ihrer Verschiebung zu verschwenken.To this end, the present invention proposes a driven machine tool, in particular an angle grinder or a straight grinder, with the features of claim 1 . Accordingly, the actuating mechanism has a shift rod which can be displaced along the longitudinal axis of the housing and which protrudes with an actuating section through a recess in the housing, and a shift lever which is pivotably mounted in a bearing point and has at least one lever arm. The shift rod is also coupled to the at least one lever arm according to the invention and is able to pivot it as a result of its displacement.

Auf diese Weise kann der Schalthebel in Richtung zu dem Antriebsschalter hin verschwenkt werden und diesen zum Einschalten drücken, oder von diesem wegverschwenkt werden, wodurch ein Ausschalten ermöglicht wird. Der Schalthebel weist hierzu wenigstens einen Hebelarm auf, der sich von seinem Lagerpunkt bis zum dem Kraftangriffs- bzw. Krafteinleitungspunkt, an dem die Schaltstange mit dem wenigstens einen Hebelarm gekoppelt ist, erstreckt. Je nach Gestaltung des Gehäuseinnenraums kann jedoch auch ein doppelarmiger Schalthebel sinnvoll sein.In this way, the shift lever can be pivoted toward the drive switch and pushes it to turn on, or pivoted away from it, allowing turning off. For this purpose, the shift lever has at least one lever arm, which extends from its bearing point to the point at which the force is applied or introduced, at which the shift rod is coupled to the at least one lever arm. Depending on the design of the housing interior, however, a double-armed shift lever can also be useful.

Durch den Einsatz eines Schalthebels wird der Krafteinleitungspunkt bzw. Kraftangriffspunkt an der Schaltstange in Richtung der Betätigungsachse verlagert. Dadurch ergeben sich deutlich geringere Querkräfte, welche durch die Lagerung aufgefangen werden müssen. Weiterhin können durch die Hebelübersetzung die Schaltkräfte größer und damit der Schalter sicherer ausgeführt werden. Die Betätigungskraft wird durch das Vorsehen des Schalthebels reduziert, sodass auch dann, wenn die Schaltstange durch sich ansammelnden Staub oder Verschmutzung schwergängiger wird, der Bediener keine nennenswert hohen Kräfte aufbringen muss, um die angetriebene Werkzeugmaschine ein- bzw. auszuschalten. Schließlich ergibt sich durch die Hebelübersetzung an der Schaltstange ein größerer Hub, was wiederum vorteilhafterweise den sich ansammelnden Staub in unkritische Bereiche zu fördern vermag.By using a shift lever, the point of force application or point of force application on the shift rod is shifted in the direction of the actuation axis. This results in significantly lower transverse forces, which have to be absorbed by the bearing. Furthermore, the switching forces can be greater and the switch can be made safer as a result of the leverage. The actuation force is reduced by the provision of the switching lever, so that even if the switching rod becomes more difficult to move due to dust or dirt accumulating, the operator does not have to exert any significant force to switch the driven machine tool on or off. Finally, the leverage on the shift rod results in a larger stroke, which in turn is advantageously able to convey the dust that collects to non-critical areas.

Als Antriebsschalter wird ein handelsüblicher Schalter, ein sogenannter Würfelschalter bzw. Druckschalter, verwendet. Hierbei handelt es sich um eine Schaltergeometrie, die von einer Vielzahl von unterschiedlichen Herstellern angeboten und in handelsüblichen Werkzeugmaschinen bereits eingesetzt wird.A commercially available switch, a so-called cube switch or pressure switch, is used as the drive switch. This is a switch geometry that is offered by a large number of different manufacturers and is already used in commercially available machine tools.

Die vorliegende Erfindung wird folglich zusammen mit einem bereits bekannten Antriebsschalter verwendet, was den Vorteil der Nachrüstbarkeit bei bereits entwickelten Werkzeugmaschinen hat. Ein weiterer Vorteil ist darin zu sehen, dass durch die Verwendung eines bestehenden Antriebsschalters die Entwicklungs- und Herstellungskosten bezüglich des Antriebsschalters gleich bleiben, während die Erfindung eine verbesserte Schaltbarkeit der Werkzeugmaschine bereitstellt.The present invention is consequently used together with a drive switch that is already known, which has the advantage of being able to be retrofitted in machine tools that have already been developed. A further advantage can be seen in the fact that the use of an existing drive switch means that the development and production costs for the drive switch remain the same, while the invention provides improved switchability of the machine tool.

Weiterhin ist erfindungsgemäß vorgesehen, dass der Lagerpunkt des Schalthebels an dem Gehäuse angeordnet ist. Hierdurch wird eine besonders einfache Montage des Schalthebels ermöglicht.Furthermore, the invention provides that the bearing point of the shift lever is arranged on the housing. This enables a particularly simple assembly of the shift lever.

Bei einer Weiterbildung der Erfindung kann die Schaltstange an einem freien Ende des Schalthebels mit dem wenigstens einen Hebelarm gekoppelt sein. Hierdurch kann ja nach Gestaltung des Lagerpunkts ein besonders langer Hebelarm bereitgestellt werden, wodurch die von der Schaltstange einzuleitende Querkraft vergleichsweise gering sein kann.In a further development of the invention, the shift rod can be coupled to the at least one lever arm at a free end of the shift lever. As a result, depending on the design of the bearing point, a particularly long lever arm can be provided, as a result of which the transverse force to be introduced by the shift rod can be comparatively small.

Das freie Ende des gekoppelten Hebelarms kann in einer Ausnehmung an der Schaltstange aufgenommen sein. Dabei kann der Schalthebel an dem freien Ende des gekoppelten Hebelarms eine abgerundete Außenkontur aufweisen und die Ausnehmung an der Schaltstange kann eine im Wesentlichen korrespondierende Kontur aufweisen. Durch das Vorsehen einer solchen abgerundeten Außenkontur, welche in eine im Wesentlichen korrespondierende Innenkontur der Ausnehmung an der Schaltstange eingreift, wird eine gelenkige Verbindung der Schaltstange mit dem Schalthebel erreicht, bei der eine Relativbewegung des Schalthebels zu der Schaltstange (bedingt durch die Schwenkbewegungen des Hebels) einer geringeren Reibung ausgesetzt ist. Zusätzlich kann im Bereich der Kopplung von Schaltstange und Schalthebel eine reibungsmindernde Beschichtung oder ein reibungsminderndes Material an den Schalthebel oder an der Schaltstange eingesetzt sein.The free end of the coupled lever arm may be received in a recess on the shift rod. The shift lever can have a rounded outer contour at the free end of the coupled lever arm, and the recess on the shift rod can have a substantially corresponding contour. By providing such a rounded outer contour, which engages in an essentially corresponding inner contour of the recess on the shift rod, an articulated connection of the shift rod with the shift lever is achieved, in which a relative movement of the shift lever to the shift rod (due to the pivoting movements of the lever) subjected to less friction. In addition, a friction-reducing coating or a friction-reducing material can be used on the shift lever or on the shift rod in the area where the shift rod and shift lever are coupled.

Die Erfindung wird nachfolgend unter Bezugnahme auf die beigefügte Figur detaillierter beschrieben, wobei diese eine bevorzugte Ausführungsform zeigt. Die erfindungsgemäßen Merkmale sind hierbei in Kombination miteinander dargestellt. Jedoch erkennt der Fachmann diese losgelöst voneinander und kann die einzelnen Merkmale der Erfindung gegebenenfalls auch zu weiteren sinnvollen Unterkombinationen zusammenführen.The invention will be described in more detail below with reference to the attached figure, which shows a preferred embodiment. The features according to the invention are shown here in combination with one another. However, the person skilled in the art recognizes these separately from one another and can, if necessary, also combine the individual features of the invention to form further meaningful sub-combinations.

Die Figur zeigt schematisch eine teilgeschnittene Draufsicht auf das Innere eines Gehäuses einer erfindungsgemäßen Werkzeugmaschine.The figure schematically shows a partially sectioned plan view of the interior of a housing of a machine tool according to the invention.

Die erfindungsgemäße Werkzeugmaschine ist nur ausschnittsweise in der Figur gezeigt und allgemein mit dem Bezugszeichen 10 bezeichnet. Sie weist im Bereich ihres Griffs ein sich entlang einer Längsachse L erstreckendes Gehäuse auf, welches aus mehreren Gehäuseteilen, beispielsweise in Topfbauweise, zusammengesetzt sein kann. In der dargestellten Ausführungsform ist ein Gehäuseteil im Griffbereich 12 abgenommen, um einen Einblick in das Gehäuseinnere zu ermöglichen. Das Maschinengehäuse ist unabhängig von dem gezeigten Gehäuseteil allgemein mit dem Bezugszeichen 14 bezeichnet.The machine tool according to the invention is only partially shown in the figure and is generally denoted by reference numeral 10 . In the area of its handle, it has a housing which extends along a longitudinal axis L and can be composed of several housing parts, for example in the form of a pot. In the embodiment shown, a part of the housing has been removed in the handle area 12 in order to enable a view of the interior of the housing. The machine housing is designated generally by the reference numeral 14 independently of the housing part shown.

Im Inneren des Gehäuses 14 erkennt man einen Antriebsschalter 16, der zum Ein- und Ausschalten einer Antriebseinheit 18 dient. Der Antriebsschalter 16 ist in der dargestellten Ausführungsform als Druckschalter ausgebildet, der in seiner Aus-Stellung durch eine integrierte Druckfeder (nicht dargestellt) vorgespannt ist. Um mithilfe des Druckschalters 16 eine zugehörige Aktivierungseinheit 20 zur Versorgung der Antriebseinheit 18 mit Energie einzuschalten, ist es daher notwendig, den Druckschalter bzw. Antriebsschalter 16 in Richtung zu der Antriebseinheit 18 gegen die Wirkung der integrierten Feder zu drücken (angedeutet durch Pfeil A).A drive switch 16 which serves to switch a drive unit 18 on and off can be seen in the interior of the housing 14 . In the illustrated embodiment, the drive switch 16 is designed as a pressure switch which is preloaded in its off position by an integrated compression spring (not shown). In order to use the pressure switch 16 to switch on an associated activation unit 20 for supplying the drive unit 18 with energy, it is therefore necessary to press the pressure switch or drive switch 16 in the direction of the drive unit 18 against the action of the integrated spring (indicated by arrow A).

Der Betätigungsmechanismus 22 zur Betätigung des Antriebsschalters 16 umfasst eine Schaltstange 24 sowie einen Schalthebel 26. Die Schaltstange 24 übernimmt dabei die Aufgabe, eine Betätigungsbewegung durch den Anwender von der Außenseite des Gehäuses in das Innere umzuleiten. Hierzu weist die Schaltstange 24 einen (nicht dargestellten) Betätigungsabschnitt auf, der eine Ausnehmung des Gehäuses 14 durchragt. Dieser Betätigungsabschnitt kann in bekannter Weise von einem Anwender im Griffbereich 12 innerhalb der Ausnehmung des Gehäuses in Längsrichtung L nach vorne oder nach hinten verschoben werden, um die Werkzeugmaschine ein- bzw. auszuschalten. Durch Verschiebung des Betätigungsabschnitts wird eine Verschiebung der Schaltstange 24 in Richtung der Längsachse L bewirkt. Diese wiederum nimmt den daran gekoppelten Schalthebel 26 mit und verschwenkt letzteren um seinen Lagerpunkt 28 am Gehäuse. Der Schalthebel 26 übernimmt dabei unter anderem die Aufgabe, die translatorische Verlagerung der Schaltstange 24 in eine Schwenkbewegung umzuwandeln, wobei infolge dieser Schwenkbewegung der mit dem Schalthebel 26 in Anlage stehende Antriebsschalter 16 in Richtung A gedrückt wird.The actuating mechanism 22 for actuating the drive switch 16 includes a switching rod 24 and a switching lever 26. The switching rod 24 takes on the task of redirecting an actuating movement by the user from the outside of the housing to the inside. For this purpose, the switching rod 24 has an actuating section (not shown) which protrudes through a recess in the housing 14 . This operating section can be pushed forwards or backwards in the longitudinal direction L by a user in the handle area 12 within the recess of the housing in a known manner in order to switch the machine tool on or off. A displacement of the shift rod 24 in the direction of the longitudinal axis L is effected by displacement of the actuating section. This in turn takes the shift lever 26 coupled to it and pivots the latter about its bearing point 28 on the housing. The shift lever 26 takes over among other things, the task of converting the translational displacement of the shift rod 24 into a pivoting movement, as a result of this pivoting movement of the drive switch 16, which is in contact with the shift lever 26, is pressed in direction A.

Wie man anhand der Figur ebenfalls erkennen kann, weist der dargestellte Schalthebel 26 einen einzigen Hebelarm auf, der sich von dem Lagerpunkt 28 an dem Gehäuse 14 bis zu dem Krafteinleitungspunkt 30 erstreckt. Der Krafteinleitungspunkt 30 ist derjenige Punkt, an dem die Schaltstange 24 mit dem Schalthebel 26 gekoppelt ist und folglich eine Druck- bzw. Zugkraft in den Schalthebel 26 einleitet. In diesem Bereich ist der Schalthebel 26 an seinem freien Ende abgerundet ausgebildet. Die zugehörige Ausnehmung 32, in der das freie Ende des Schalthebels 26 aufgenommen ist, weist eine korrespondierende Kontur auf. Hierdurch wird eine möglichst reibungsfreie Verlagerung des Schalthebels relativ zu der Schaltstange 24, wenn der Schalthebel 26 verschwenkt wird, erreicht.As can also be seen from the figure, the shift lever 26 shown has a single lever arm which extends from the bearing point 28 on the housing 14 to the point 30 of force application. The force introduction point 30 is the point at which the shift rod 24 is coupled to the shift lever 26 and consequently a compressive or tensile force is introduced into the shift lever 26 . In this area, the shift lever 26 is rounded at its free end. The associated recess 32, in which the free end of the shift lever 26 is received, has a corresponding contour. As a result, a displacement of the shift lever that is as friction-free as possible relative to the shift rod 24 when the shift lever 26 is pivoted is achieved.

Der Schalthebel 16 berührt im Bereich eines Berührpunktes 34 den Antriebsschalter 16 zumindest bei seiner Verschwenkbewegung in Richtung zu dem Antriebsschalter, wobei der Schalthebel 26 eine Druckkraft auf den Antriebsschalter 16 ausübt. Der Berührpunkt 34 ist in einem geringeren Abstand zu dem Lagerpunkt 28 angeordnet als der Krafteinleitungspunkt 30. Hieraus ergibt sich basierend auf dem allgemeinen Grundsatz des Momentengleichgewichts an einem Hebel eine Kraftübersetzung, bei der die von der Schaltstange 24 eingeleitete Kraft um den Faktor geringer ist als die auf den Antriebsschalter 16 ausgeübte Druckkraft, um den der Abstand von dem Berührpunkt 34 zu dem Lagerpunkt 28 kleiner ist als der Abstand von dem Krafteinleitungspunkt 30 zu dem Lagerpunkt 28.The shift lever 16 touches the drive switch 16 in the area of a contact point 34 at least during its pivoting movement in the direction of the drive switch, with the shift lever 26 exerting a compressive force on the drive switch 16 . The contact point 34 is arranged at a smaller distance from the bearing point 28 than the force application point 30. Based on the general principle of moment equilibrium on a lever, this results in a force transmission in which the force introduced by the shift rod 24 is lower by the factor than the compressive force exerted on the drive switch 16 by which the distance from the contact point 34 to the bearing point 28 is smaller than the distance from the force application point 30 to the bearing point 28.

Der Schalthebel 26 und die Schaltstange 24 müssen nicht fest miteinander verbunden sein. Es reicht, wenn die Schaltstange 24 in der Weise mit dem Schalthebel gekoppelt ist, dass ihre Translationsbewegung ein Verschwenken des Schalthebels 26 zur Folge hat.The shift lever 26 and the shift rod 24 do not have to be firmly connected to one another. It is sufficient if the shift rod 24 is coupled to the shift lever in this way is that its translational movement causes the shift lever 26 to pivot.

Mit der vorliegenden Erfindung wird eine besonders einfache und kostengünstige Umsetzung eines Betätigungsmechanismus vorgeschlagen. Durch Verwendung eines Schalthebels können die von der Schaltstange aufzubringenden Druck- bzw. Zugkräfte gegenüber dem Stand der Technik deutlich verringert werden. Dieses ist zum einen sehr vorteilhaft für die Bedienung durch den Anwender, da selbst dann, wenn die Schaltstange infolge einer Anlagerung von Staubpartikeln schwergängig geworden ist, der Anwender weiterhin keine nennenswert hohen Kräfte zum Bedienen der Schaltstange aufbringen muss. Ferner ist jedoch auch vorteilhaft, dass dadurch, dass die Betätigungskraft durch den Schalthebel reduziert wird, auf die Schaltstange ebenfalls geringere Reaktionskräfte einwirken, sodass diese gegenüber dem Stand der Technik einer geringeren Belastung ausgesetzt ist. Hierdurch wird die Lebensdauer des Betätigungsmechanismus erhöht.With the present invention, a particularly simple and cost-effective implementation of an actuating mechanism is proposed. By using a shift lever, the compressive or tensile forces to be applied by the shift rod can be significantly reduced compared to the prior art. On the one hand, this is very advantageous for operation by the user, since even if the shift rod has become sluggish as a result of accumulation of dust particles, the user still does not have to exert any significant force to operate the shift rod. Furthermore, however, it is also advantageous that because the actuating force is reduced by the shift lever, lower reaction forces also act on the shift rod, so that it is exposed to less stress than in the prior art. This increases the service life of the operating mechanism.
