Abstract

A transmission (GA) for an axle drive (1) of a motor vehicle includes a drive shaft (AN), two output shafts (AB1, AB2), at least four shafts (W1, W2, W3, W4), a differential, and two interconnected planetary gear sets (PS1, PS2). The drive shaft (AN) is a hollow shaft, and the drive shaft (AN) is coaxial with at least one of the two output shafts (AB1, AB2). The differential (D) is arranged, at least partly, within a cylindrical volume. An outer shell surface of the cylindrical volume is defined by an inner shell surface of a sun gear (SO2) of the second planetary gear set (PS2). A diameter of inner shell surface corresponds to an inner diameter of the sun gear (SO2) of the second planetary gear set (PS2).
