Abstract: A transmission cooling device includes a transmission housing part for housing rotating transmission elements and a fan, which is connected to the transmission housing part, for providing a cooling air flow against an outer side of the transmission housing part. The fan has a conveying element, which communicates with a hollow fan ring, for generating an operating flow within the fan ring. The fan ring communicates via at least one discharge opening with a volume provided radially within the fan ring in such a way that the operating flow generates the cooling air flow by a suction jet effect. Indirectly generating the cooling air flow with the aid of the operating flow generated by the conveying element in the hollow fan ring results in good cooling with a large flow cross section of the cooling air flow with small installation space requirement, thereby enabling space-saving cooling of a transmission.
