The invention relates to a drive system for the individual drive of both driven wheels of a driven wheel pair or similar for a motor vehicle, comprising two infinitely variable drive motors (2, 6), in drive connection with a corresponding drive wheel (4, 8) or similar by means of a gearbox arrangement. The gearbox arrangement comprises two gearbox units, one of the gearbox units is a selectable gearbox (10, 40) design and the other gearbox is a bevel-gear gearbox (54, 64; 70, 72) with a fixed ratio and the bevel-gear gearbox (54, 64; 70, 72) comprises a spur gearset and a bevel gearset. The drive ratio may be varied with the selectable gearbox (10, 40) whilst the bevel-gear gearbox (54, 64; 70, 72) permits the arrangement of the driveshafts (14) of the drive motor (2, 6) perpendicular to the rotational axis of the driven wheels (4, 8). The spur gearset fitting permits, for example, a higher or lower positioning of the driveshafts (28, 45) according to vehicle type for each gearbox arrangement. Furthermore, various relative arrangements of the bevel gears of the bevel-gear gearbox permit the angle of the drive motors (2, 6) and the selectable gearboxes (10, 40) to the vehicle longitudinal axis and the drive angle of the driveshafts (28, 45) to be adjusted, such that said drive system may be used with an essentially similar component assembly for various vehicle types.
