Hydraulic friction clutch - has stepped sections of different diameters on hub and shaft ends

摘要

The hub (6) of the drive disc (5) has two stepped sections, which are axially offset relative to each other and have different internal diameters. The flanged shaft (1,4) has two similar end sections, corresponding with those of the hub. The first smaller shaft end section is formed as a slide or transition fit. The larger section is formed as a groove toothing. During assembly, an internal toothing in the hub is formed by the external toothing of the shaft digging into the hub. ADVANTAGE - Technically perfect connection between shaft and hub, which accommodates different expansions of steel and aluminium.
