Abstract
An electrodynamic drive system (2) for a vehicle having, between a drive source (4)and a transmission (16), a planetary gear drive (12) which incorporates three elements, namely, a sun gear (50), an internal gear (10) and a planetary gear carrier (32). A first element (32) is connected to the transmission (16), a second element (10) is connected to the drive source (4) and a third element (50) is bound to at least one electric motor (22), thus an abrasion-free starting element is formed for the vehicle.
