Abstract
A viscous coupling having a flushing pump for a drive assembly, in which the abrasion particles occurring as a result of friction between the plates are flushed out of the coupling housing. This is achieved by connecting the viscous coupling to a storage and a supply channel, and the flushing pump is driven as a result of relative movement of the two sets of plates in the viscous coupling and ensures that the viscous fluid flushes the interior of the viscous coupling.
