Double gear (1) for a drive train (3) of a motor vehicle (500) with two electric machines (5, 7), each of which is used to drive a wheel (506, 508) after a speed reduction by its own individual gear (15, 17) in the Double gear (1) is designed, wherein a single gear (15, 17) is a two-stage spur gear with exactly three positions (19, 21, 23) for gear centers (25, 27, 29) in a gear housing (31), characterized in that the Motor vehicle (500) intended to accommodate the double transmission (1) has a passenger compartment, and input shafts (33, 35) of the double transmission (1) and output shafts (37, 39) of the double transmission (1) when the double transmission (1) is in an installation position a central area (M), based on a transverse extension to a direction of travel, are arranged lying at the same height, resulting in a reference plane (B) within the transmission housing (31) and one of the positions (19, 21, 23) a Position (21) is for a central axis (45), this position (21) being angled to the reference plane (B) as a position (21) remote from a housing bottom (51) of the gear housing (31), which position leads to a Increase in the position (21) of the central axis (45) with respect to the reference plane (B) and thus to a corner of a triangle (47) resting on the reference plane (B) through its longest side, with one on the central axis (45) Straight line (g) can be drawn from one of the other gear wheel centers (25, 29) forming an angle (α), the angle (α) having a value that lies within an angular range between 5 ° and 70 ° from the reference plane (B ) deviates, and the middle position (21) is formed by a stationary axle (45) which carries a rotatably mounted step gear (49, 49 ', 50, 50'), a first and a second row of teeth of the step gear (49, 49 ', 50, 50') has a co-rotating inclination of the teeth (57, 57 ', 59, 59').
