Abstract:
1. An axle-drive unit for a motor vehicle having a first and a second driven axle which comprises a first and a second differential ( 18 , 19 ) in a housing driven by an engine/transmission block ( 1 ), the first differential ( 18 ) dividing the torque fed to it between a first half axle ( 9 ) of the first driven axle ( 8 , 9 ) and the second differential ( 19 ), and the second differential ( 19 ) furthermore dividing the torque fed to it between a second half axle ( 8 ) of the first driven axle ( 8 , 9 ) and a power take-off ( 7 ) for the second driven axle ( 16 , 17 ), the two differentials ( 18 , 19 ) being spur-gear planetary gears with parallel axes, the sun wheels ( 32 , 43 ) of which are in each case connected in terms of drive to the half axles ( 8 , 9 ) of the first driven axle, and planet wheels ( 36 , 38 ) of the two differentials ( 18 , 19 ) meshing with their common ring gear ( 35 ), a first planet carrier ( 23 ) being connected in a rotationally fixed manner to the housing and a second planet carrier ( 40 ) being connected in terms of drive to the power take-off ( 7 ) for the second driven axle, wherein a) the housing ( b) the ring gear ( c) the ring gear outer circumferential surface (
