Abstract: A motor housing 20 for an axial flux motor 10. The motor housing 20 includes at least one housing portion 22, 24 which is of at least partially double-walled configuration, in order to configure an internal cooling channel 40 in the housing portion 22, 24. The cooling channel 40 extends in a substantially annular manner in the circumferential direction 6 between an inlet 41a and an outlet 41b, in order, during operation, to produce a first cooling flow 82 which flows substantially in the circumferential direction 6 through the cooling channel 40. Furthermore, the cooling channel 40 includes a plurality of transverse ribs 50.

Abstract: 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.

Abstract: The invention refers to a fan system (10) comprising a fan shroud (14) and a ring fan (12) having a hub (30), a plurality of fan blades (32), and a ring structure (34). The ring structure (34) has a ring member (46) and a flange member (48), the ring member (46) having a hollow cylindrical shape, the flange member (48) extending radially outwardly from the ring member (46). The fan shroud (14) has an annular shroud flange (54), a shroud body (56) and a plurality of shroud guide vanes (58), the shroud flange (54) extending radially outwardly from the shroud body (56) and being disposed along the rotary axis (A) between the flange member (48) and the shroud body (56), the shroud body (56) being disposed about the ring member (46) and having a first body portion (70), a second body portion (72) and a divergent nozzle (74). A recirculation throttle (88) is formed by the shroud body (56) and the ring member (46) at a location where the first and second body portions (70, 72) of the shroud body (56) intersect one another. The divergent nozzle (74) and a trailing end (50) of the ring member (46) cooperate to form a dynamic sealing feature (90).
