ABSTRACT:
An electrical drive system for a vehicle with a skid steering element exhibits a homogeneous electrical drive engine and a homogeneous gear unit (16, 18) on the left and on the right side in each case, which are propelled by a drive engine (2,4), assigned in each case, and over a power drive flange (28, 40) to propel a track or a drive wheel. Two transfer elements (26, 24) of the left gear unit (16), which do not form the drive, are directly connected by a mechanical gear train crosswise in each case with both transfer elements (36, 38) of the right gear unit, which do not form the drive.
