NAAF MET MEERDERE VERSNELLINGEN MET FRICTIEKOPPELING VOOR BEGRENSBARE SCHAKELBELASTINGEN.

摘要

The bicycle multi-gear hub, with a friction clutch, has pawls (11a-11f) moved to the corresponding switch sleeve (10a-10c) according to their relative rotary speed. A friction unit is between a switch sleeve and another component giving support in a positive fit. It slips on breaching a defined friction force so that the switch sleeve does not rotate against the pawl.
