Multi-gear transmission device and power tool
Abstract:
The invention relates to a multi-gear transmission device, particularly a two-gear transmission device, for transferring a drive torque from an input side to an output side, which transmission device has at least two selectable gear ratios. The multi-gear transmission device further has a multi-stage clutch device, particularly a two-stage clutch device, with at least two different, selectable limit torques. According to the invention, the multi-stage transmission device has at least two preferably switchable translating gear pairs, and the multi-stage clutch device is included in the translating gear pairs.
