摘要

The clutch hub (118) has radial internal gears (120) which are engaged with the shaft gear teeth (122). A radial external teeth (116) is engaged with the friction element (112). A radial channel (138) for a passage of a liquid is arranged towards the friction element. The clutch hub main portion is produced as sintered portion.
