Car AUDI A4 quattro has a constant full drive. To a drive of back wheels are in addition applied: карданный a shaft, differential of the back axis, two power shafts of back wheels, and also interaxal differential of Torsena.

The kardannyj shaft transfers a twisting moment from a check point of a forward axis to differential of a back axis. From differential of a back axis two power shafts transfer movement to back wheels. For indemnification of various turns of wheels and twisting moment distribution between forward and back axes, depending on traffic conditions, on models with a full drive the self-blocked interaxal differential of Torsena which can transfer a variable twisting moment to forward and back wheels is in addition established.

Features of towage

Models with a full drive can be towed with the lifted forward or back wheels.

Thus, however, the car cannot be towed on distance more than 50 km and speed of towage should not exceed 50 km/hour. To be towed the car should on the special conveyor.

With a full drive the engine at towage should not work for cars. The general instructions on towage are resulted in section of Poddomkrachivanie and towage.
