A portal axle drive for a vehicle axle of an electric vehicle with driving wheels, comprising:

• a drive shaft (AN) with an input axis (a);
• an output shaft (AB) with an output and wheel axis (b), the input axis (a) and the output axis (b) have a portal offset (c);
• a first gear stage (Ü1) arranged between the drive shaft (AN) and the output shaft (AB);
• a second gear stage (Ü2) arranged next to the first gear stage (Ü1) in an axial direction;
• and
• an engagement device (SE) arranged next to the second gear stage (Ü2) in an axial direction, the first gear stage (Ü1) and the second gear stage (Ü2) engageable via the engagement device (SE),
• wherein each of the first gear stage (Ü1) and the second gear stage (Ü2) include an input pinion (Z1, Z3), an output gearwheel (Z2, Z4), and two intermediate gears (ZR1, ZR2, ZR3, ZR4),
• wherein the input pinions (Z1, Z3) of the first and second gear stages (Ü1, Ü2) are configured as fixed gears on the drive shaft (AN),
• wherein the output gearwheels (Z2, Z4) of the first and second gear stages (Ü1, Ü2) are configured as idler gears on the output shaft (AB), and
• wherein the output gearwheel (Z4) of the second gear stage (Ü2) is rotatably arranged on the output gearwheel (Z2) of the first gear stage (Ü1).
