Combined friction disc and fluid friction coupling

摘要

The coupling arrangement (1) has a drive shaft (2) that includes friction surface (20) relative to an output unit (9). The output unit is moved by energizing an energisable winding (4). A movable armature (7) is formed with friction surface (19) comprising friction disc coupling agents. The fluid (16) such as silicon oil is filled in shear gap (21) comprising fluid friction clutch coupler (14). The friction disc coupling agents are combined with fluid friction clutch coupler. The shear gap is limited by the movable armature.
