Drive train of an all-wheel drive vehicle comprising clutches and method for controlling and regulating a drive train

[0028]FIG. 1 shows a schematic representation of a power train 1 of an all-wheel drive vehicle. Power train 1 comprises a driving unit 2 and a main transmission 3, each of which in practice is a known transmission. The driving unit 2 is represented in the application example of FIG. 1 as a braking force machine and can be built from an electric motor for a beneficial further training.

[0029] Between the main transmission 3, which is intended for showing different conversion ratios, and a first driven vehicle axle 4, which in a known way can be connected with at least one driven wheel 4A, 4B, is a first clutch k_VA arranged in a longitudinal power train. The first clutch k_VA is between the main transmission 3 and a mechanism 6 which balances through differential rotational speeds and is placed between the driven wheels 4A and 4B, the first vehicle axle 4, whereby the mechanism 6 is used as a known transverse distributing transmission.

[0030] Beyond this, a second clutch k_HA_L as well
