Abstract

An all-wheel distributor transmission (1) is described for a motor vehicle comprising a planetary gear set as multiplication step (2) for a switchable off-road gear and a planetary gear set (3) with variable division for distributing a drive torque onto a front axle and a rear axle. The all-wheel distributor transmission (1) also has an adjustable lock (4) for locking between the front axle and the rear axle, the lock (4) and the multiplication step (2) being actuatable via a controllable drive device (5). The drive device (5) comprises a drive shaft (6) and two output shafts (7, 8), the first output shaft (7) being in operative connection with the multiplication step (2) and the second output shaft (8) being in operative connection with the lock (4). A torque introduced via the drive shaft (6) can be applied on the first or the second output shaft (7 or 8) according to a control of a shift unit (10) for actuating the lock (4) or the multiplication step (2).
