Abstract

The invention relates to a drive unit for a motor vehicle having a hydrodynamic retarder and a drive train with an engine and a transmission. The hydrodynamic retarder is comprised of a rotor impeller wheel and a stator impeller wheel and is coordinated with the main drive train in a manner such that the rotor impeller wheel of the hydrodynamic retarder is driven by the drive train. The operating fluid of the hydrodynamic retarder is a medium used for cooling the vehicle and a clutch is arranged between the drive train and the hydrodynamic retarder.
