The combination Several clutches are made via a shift plate in the lubricated interior of the Gear and impact mechanism assembly.
Nach der DE4000822 ist ein drehversetzbarer Modiwahlschalter mit einem Exzenterzapfen schmiermitteldicht zwischen einer mit Schmierfett gefüllten Getriebebaugruppe und dem trockenen Äusseren angeordnet. Alle Schaltfunktionen erfolgen im Innern der Getriebe- und Schlagwerksbaugruppe.According to DE4000822 is a rotatable mode selector switch with an eccentric pin Lubricant-tight between a gear assembly filled with grease and the arranged dry exterior. All switching functions take place inside the gearbox and Percussion mechanism.
Nach der DE19937767 sind einigen Betriebsmodi weitere elektrische und mechanische Sonderfunktionen zugeordnet, welche über ein, zwischen der Getriebebaugruppe und dem Aussengehäuse angeordnetes sowie vom Modiwahlschalter mit einem Exzenterzapfen versetzbares, Schaltgestänge in den Motorschalter eingreift sowie mit einem endseitigen Magneten über einen Hall-Sensor die Steuerelektronik des Antriebsmotors im schmierstofffreien Motorgehäuse beeinflusst, welche beim «Meisseln» den Motorschalter arretiert und die Motordrehzahl erhöht. Es ist nur eine geschmierte Getriebe- und Schlagwerksbaugruppe vorhanden.According to DE19937767, some operating modes are further electrical and mechanical Special functions assigned, which via a, between the gear assembly and the Outer housing arranged and from the mode selector switch with an eccentric pin displaceable, shift linkage engages in the motor switch and with an end Magnets via a Hall sensor control electronics of the drive motor in the Lubricant-free motor housing, which affects the motor switch when chiseling locked and the engine speed increased. It's just a lubricated gear and Striking mechanism assembly available.
Die Aufgabe besteht in der Realisierung eines Modiwahlschalters mit weiteren Sonderfunktionen für eine kombinierten Elektrohandwerkzeugmaschine mit mehreren schaltbaren Schaltkupplungen in zumindest zwei unterschiedlich geschmierten, schmiermitteldichten Getriebe- und Schlagwerksbaugruppen. The task is to implement a mode switch with others Special functions for a combined electric hand machine tool with several switchable clutches in at least two differently lubricated, Lubricant-tight gear and impact mechanism assemblies.
Die Aufgabe wird im Wesentlichen durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The task is essentially solved by the features of the independent claims. Advantageous further developments result from the subclaims.
