The all-wheel drive model of the AUDI A3 car is equipped with a constant full drive. The following elements are in addition necessary for a drive of back wheels:
Knot of selection of capacity from RKPP of a forward axis to provide movement transfer on the driveshaft which connects RKPP to back differential. From differential of a back axis movement through power shafts is transferred to back wheels.
For possibility of placement of differential of a back axis the all-wheel drive AUDI A3 model has the double cross-section lever of a back suspension bracket and a fuel tank, two-piece.
For alignment of various turns of forward and back axes at a full drive of the car and for torque distribution depending on traffic conditions, between forward and back axes, the coupling of Haldex fixed on differential of a back axis is applied.
Coupling of Haldex represents disk coupling with electronic control and a hydraulic drive. Depending on the signals arriving from various sensors as, for example, from monitors the engine and ABS the monitor coupling of Haldex regulates process of connection of a back axis. The control system of a full drive distinguishes the reason of a probuksovyvaniye of separate wheels and various number of turns of wheels and according to it distributes a torque between lobbies and back wheels. The back axis can be disconnected from a power drive that removes restrictions at towage with the lifted lobbies or back axes completely. The all-wheel drive model can be besides equipped with all electronic and hydraulic systems, as, for example, ABS, EDS, ASR, EBV and ESP.
Towage of cars with a full drive
Cars with a full drive can be towed on distance no more than 50 km with a speed no more than 50 km/h. Otherwise towage should be made on the special conveyor by complete loading.
