Friction device for gear wheel fixed to shaft - has centrifugal spring action with spring elements for radially inwards action

摘要

The friction device operates with a gear wheel (150 fixed on a shaft (16),and has at least one friction body (10 - 13). At least one spring element operates with an opposing, synchronised body (17) against the friction action, rising via centrifugal force. The spring element comprises at least one ring element (1), with at least one plate spring tongue (2 - 5) which operates in an essentially radially inwards direction. USE/ADVANTAGE - For gear change transmission,with compact design,easy mfr.and assembly.
