Abstract
In a motor vehicle having a radiator for cooling a cooling medium and a fan driven by a driveshaft of an internal combustion engine, the fan being arranged between the radiator and the internal combustion engine, a drive system for the fan has a viscous coupling and a vibration damper, which includes an elastic element and which dampens and/or decouples the vibrations between the driveshaft-side output of the internal combustion engine and the fan. The viscous coupling and the vibration damper are arranged between the internal combustion engine and the fan, wherein the vibration damper is arranged between the fan and the viscous coupling and dampens and/or decouples vibrations acting between the fan and the viscous coupling.
