| Zusammenfassung: | The crank (26) has a pressure shell (29) which can be moved axially against a crank eye endface via a setting ring (30) connected to it. A locking wheel (20) is clamped axially in one direction when the crank is turned in one direction, and released when it is turned in the other. A torque decoupling device (34) is fitted for transmitting the torque to the cable drum shaft. This device has a hollow shaft which can move axially and radially in the pressure shell. It can be brought into a firm grip with the setting ring, and released from this grip. |
