An additional stabilizer is welded to the ends of the longitudinal levers. This design is highly resistant to lateral bending and ensures optimal longitudinal stability (see illustration 1.0).
The shock absorbers are located almost in the center of the wheels and take on the vertical load. To ensure maximum trunk capacity, the shock absorber strut coil spring is shifted downwards.
The design feature of the suspension of the wheels on longitudinal levers connected by a beam fixed to the body is that, under simultaneous load on both struts, it behaves in the same way as a suspension on longitudinal balance beams, and under variable loads of different values, like a suspension on diagonal levers
The quattro models' rear independent suspension is made with double wishbones. The wishbones are in the shape of a triangle and are additionally connected by a stabilizer. The stabilizers and cylindrical springs are combined into a small shock absorber strut (see illustration 1.0a and 1.0b).
The location of the upper wishbones above the wheels allowed the side members to be moved downwards, and the wheel arches shifted to the sides provide optimal luggage compartment dimensions.
The rear wheel drive differential is bolted to the auxiliary frame, which in turn is secured to the body with reinforced brackets.
The front suspension is a modified model of the suspension installed on AUDI Coupe cars. Additional polyurethane buffers on the shock absorber struts provide softening and damping of fairly strong body vibrations (see illustration 1.0v).
The design of the anti-roll bars of the front and rear suspensions is calculated in such a way as 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.
