Fluid friction coupling has drive disc, housing of base and cover, drive shaft, operating and storage chambers, inflow and return flow, turbulence coupling, and permanent magnets

摘要

The fluid friction coupling has a drive disc (2) and a housing (4) consisting of a base body (5) mounted on a drive shaft (1), and a cover (6). An operating chamber (7) in the housing forms operating gaps with the drive disc. A storage chamber (9) divided by a partition (8) from the operating chamber and connected by an inlet (10) and return flow (14,15). A turbulence coupling is positioned between the drive disc and housing and transmits a defined torque. The turbulence coupling consists of pairs (16) of permanent magnets each of a coaxial copper and soft iron ring(18,19) with air gap (20) between.
