An additional stabilizer is welded to the ends of the trailing arms. This design is highly resistant to lateral bending and provides optimum longitudinal stability (see illustration 1.0).
The suspension struts are located almost in the center of the wheels and take on the vertical load. To ensure maximum luggage capacity, the suspension strut coil spring is shifted downwards.
A design feature of the suspension of wheels on trailing arms connected by a beam mounted on the body is that, with a simultaneous load on both racks, it behaves in the same way as a suspension on longitudinal balancers, and under variable loads of different values, like a suspension on diagonal levers
The rear independent suspension of the quattro models is double wishbone. The transverse levers, in turn, are made in the form of a triangle and are additionally connected by a stabilizer. Stabilizers and coil springs are combined into a small suspension strut (see illustration 1.0a and 1.0b).
The location of the upper transverse levers above the wheels made it possible to shift the side members down, and the wheel arches shifted to the sides provide optimal trunk dimensions.
The rear wheel drive differential is bolted to the auxiliary frame, which in turn is fixed to the body with reinforced brackets.
The front suspension is a modified model of the suspension installed on AUDI Coupe cars. Additional buffers made of polyurethane on the suspension struts provide softening and damping of fairly strong body vibrations (see illustration 1.0c).
The design of the anti-roll bars of the front and rear suspensions is designed to prevent significant lateral vibrations and ensure neutral and even understeer of the car.
Compared to previous models, the front suspension of the AUDI 80 has been increased by 38 mm.
