Patent abstract

A transfer case (12) for distributing a driving torque of an input shaft (19) between two drivable output shafts (22, 29) is described. The transfer case (12) is realized with two controllable and adjustable frictionally engaged clutches (k_VA, k_HA), which are arranged between the input shaft (19) and the output shafts (22, 29) and whose transfer capabilities can be respectively adjusted via separate actuating devices (10, 11). A driving torque can be distributed between the drivable output torques (22, 29) in dependence upon the set transfer capabilities of the clutches (k_VA, k_HA). One clutch (k_HA) can also be radially enclosed by the other clutch (k_VA).
