Abstract

Bei einem Drehschlagschrauber (100) mit einem Schlagwerk (122) zum schlagenden Antrieb einer Abtriebswelle (124) und mit einem Betriebsartenumschaltelement (123) zum Umschalten zwischen einem nicht-schlagenden Betrieb und einem schlagenden Betrieb des Schlagwerks (122), ist ein Sensorelement (162) vorgesehen, das dazu ausgebildet ist, einen Betriebsparameter des Drehschlagschraubers (100) zu erfassen, der zur Bestimmung eines Umschaltzeitpunkts zur Umschaltung vom nicht-schlagenden in den schlagenden Betrieb des Schlagwerks (122) auswertbar ist.

Figure imgaf001
In a rotary impact driver (100) having a percussion mechanism (122) for driving an output shaft (124) and an operating mode switching element (123) to switch between non-impact operation and impact operation of the percussion mechanism (122), a sensor element (162 ) is provided, which is adapted to detect an operating parameter of the rotary impact wrench (100), which can be evaluated to determine a switching time for switching from non-impacting to the striking operation of the impact mechanism (122).
