A motor housingfor an axial flux motor. The motor housingincludes at least one housing portionwhich is of at least partially double-walled configuration, in order to configure an internal cooling channelin the housing portion. The cooling channelextends in a substantially annular manner in the circumferential directionbetween an inletand an outlet, in order, during operation, to produce a first cooling flowwhich flows substantially in the circumferential directionthrough the cooling channel. Furthermore, the cooling channelincludes a plurality of transverse ribs

Motor housing for an axial flux motor

Disclosed is a viscous coupling that has a housing that carries ribs that are arranged concentrically about a central axis. A rotor is provided that can rotate relative to the housing about the central axis in a predetermined direction. The rotor also carries ribs, and the ribs of the housing and the rotor are arranged in a working chamber surrounded by the housing. Also provided is a fluid reservoir. A fluid discharge line leads from the working chamber to the fluid reservoir. A wiper is moveably arranged between the housing and the rotor and scrapes fluid from the rotor and feeds it to the fluid discharge line. A stop is provided for the wiper and is arranged next to the rotor.

Viscous coupling

The invention refers to a fan system () comprising a fan shroud () and a ring fan () having a hub (), a plurality of fan blades (), and a ring structure (). The ring structure () has a ring member () and a flange member (), the ring member () having a hollow cylindrical shape, the flange member () extending radially outwardly from the ring member (). The fan shroud () has an annular shroud flange (), a shroud body () and a plurality of shroud guide vanes (), the shroud flange () extending radially outwardly from the shroud body () and being disposed along the rotary axis (A) between the flange member () and the shroud body (), the shroud body () being disposed about the ring member () and having a first body portion (), a second body portion () and a divergent nozzle (). A recirculation throttle () is formed by the shroud body () and the ring member () at a location where the first and second body portions () of the shroud body () intersect one another. The divergent nozzle () and a trailing end () of the ring member () cooperate to form a dynamic sealing feature ().
