A transfer gearbox device, comprising a differential gear with a crown wheel in a first oil chamber, and a friction clutch in a second oil chamber. The first oil chamber comprises a first oil sump and the second oil chamber comprises a second oil sump. A valve is between the first oil chamber and the second oil chamber. When the valve is open, oil can pass via the valve out of the first oil chamber into the second oil chamber. When the valve is closed, oil cannot pass via the valve out of the first oil chamber. When the valve is open, by rotating the crown wheel, oil is conveyed by the crown wheel from the first oil sump into a first oil collector and is guided therefrom via a first oil guide and via the valve to the friction clutch cool and/or to lubricate the friction clutch.
