Tool device with a device for switching between a first and second transmission stage by reversing the direction of rotation

摘要

The tool (1) has a switching device (10) for switching between two transmission stages of a one-stage planetary gear (8). The switching device includes a first blocking unit and a first catch unit coupled to a planetary gear component i.e. ring gear, and a second blocking unit and a second catch unit coupled to another planetary gear component. The blocking units block a movement of the planetary gear components against a backward direction (13). The catch units transmit a torque of the planetary gear components to a drive output shaft (6) in a forward direction (12). The blocking units are designed as a freewheel mechanism or as a blocking pawl. The catch units are formed as the freewheel mechanisms.
