Abstract

Ein Elektrowerkzeug umfasst ein, in einem Getriebegehäuse (6) gelagertes, mehrstufiges Getriebe (1) und eine Schaltvorrichtung (2) zum Umschalten des Getriebes (1) von einer Getriebestufe in eine andere Getriebestufe. Die Schaltvorrichtung (2) weist einen federbeaufschlagten, in mehrere Schaltstufen bringbaren Schaltschieber (3) und einen, von diesem betätigbaren auf ein axial verschiebbares Schaltrad (4a, 4b) einwirkenden, federnd ausgebildeten Schaltbügel (5a, 5b) auf. Das Getriebe (1) umfasst mehrere axial verschiebbare Schalträder (4a, 4b), wobei jedes Schaltrad (4a, 4b) jeweils mit einem Schaltbügel (5a, 5b) zusammenwirkt und die Schaltbügel (5a, 5b) mittels dem Schaltschieber (3) betätigbar sind.

Figure 00000001
A power tool comprises a multistage transmission (1) mounted in a transmission housing (6) and a switching device (2) for switching the transmission (1) from one gear stage to another gear stage. The switching device (2) has a spring-loaded, in several stages engageable slide switch (3) and one, actuated by this on an axially displaceable ratchet wheel (4a, 4b) acting, resiliently formed switch bracket (5a, 5b). The transmission (1) comprises a plurality of axially displaceable shift wheels (4a, 4b), each shift gear (4a, 4b) each with a shift bracket (5a, 5b) cooperates and the shift bracket (5a, 5b) by means of the slide switch (3) can be actuated ,
