ALL-WHEEL DISTRIBUTOR GEARBOX FOR A MOTOR VEHICLE

摘要

The invention relates to an all-wheel distributor gearbox (1) for a motor vehicle comprising a planetary gear train as a multiplication step (2) for a switchable off-road gear mode and a planetary gear train (3) with variable division for a distributing a drive torque onto a front axle and a rear axle. The all-wheel distributor gearbox (1) also comprises an adjustable lock (4) for locking between the front axle and the rear axle, the lock (4) and the multiplication step (2) being controlled via a controllable drive device (5). The drive device comprises a drive shaft (6) and two output shafts (7, 8), the first output shaft (7) cooperating with the multiplication step (2) and the second output shaft (8) cooperating with the lock (4). Torque introduced via the drive shaft (6) can be applied onto the first or the second output shafts (7 or 8) according to control of the shift unit (10) for actuating the lock (4) or the multiplication step (2).
