The all-wheel drive model of car AUDI A3 is equipped by a constant full drive. Following elements are in addition necessary for a drive of back wheels:
Knot of selection of capacity from РКПП a forward axis to provide movement transfer on карданный a shaft which connects РКПП to back differential. From differential of a back axis movement through power shafts is transferred to back wheels.
For possibility of placing of differential of a back axis all-wheel drive model AUDI A3 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 distribution of a twisting moment depending on traffic conditions, between forward and back axes, coupling Haldex fixed on differential of a back axis is applied.
Coupling Haldex represents disk coupling with electronic control and a hydraulic drive. Depending on the signals arriving from various gauges as, for example, from monitors the engine and ABS the monitor coupling Haldex regulates process of connection of a back axis. The control system of a full drive distinguishes the reason пробуксовывания separate wheels and various number of turns of wheels and according to it distributes a twisting moment between forward and back wheels. The back axis can be disconnected from a power drive that removes restrictions at towage with the lifted forward or back axes completely. The all-wheel drive model, besides, can be equipped by 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/hour. Otherwise towage should be made on the special conveyor by full loading.
