Load-switching multi-gear hub with controlled jaw clutch has loaded coupling piece which is uncoupled by gear shift support device when changing to lower gear

摘要

The multi-gear hub includes a planetary transmission. When shifting to a lower gear, the coupling piece (11), which is under load, is uncoupled by a gear shift support device. When shifting to a higher gear, the axially movable coupling element (12) is uncoupled automatically and forcibly by the overtaking coupling components,
