Abstract: A fan clutch is provided to which a fan may be removably attached with the aid of a flange ring, the fan clutch having a housing that comprises a first front housing part and a second rear housing part to which the flange ring is attachable with the aid of connecting elements. The housing has circumferential attachment niches which are situated in an offset manner in the circumferential direction on both the front and the back of the housing and into which attachment tabs situated on the flange ring are insertable either from the front of the fan clutch or from the rear thereof.

Abstract: A fan drive (1) includes a drive shaft (6), a fluid friction clutch (2) as well as a fan (3). The fluid friction clutch (2) includes a drive disc (5) as well as a housing (4) having a front-end housing part (4a) and a rear-end housing part (4b). The housing (4) is journalled on a drive shaft (6) via at least one bearing (7). Air flows against the fluid friction clutch (2) and the fan (3) in flow direction (L). An air-conveying unit (13) is mounted in flow direction (L) behind the fluid friction clutch (2). The fan drive is especially for a motor vehicle.
