Abstract

A drive arrangement for an element vehicle, having first and second drive wheels (R1, R2), a first electric machine (EM1) and a second electric machine (EM2) with a common rotational axis (m), a manual transmission (G3) with a transmission input shaft (EW) and a transmission output shaft (AW) and an axle differential (DI) with a differential input (DIK) and two differential output shafts (3a, 3b). The first electric machine (EM1) is connected to the transmission input shaft (EW) and the transmission output shaft (AW) is connected to the differential input (DIK), and the second electric machine (EM2) can, if necessary, be engaged as an additional drive.
