199000396 - INTRODUCTION - REAR SUSPENSION

The rear suspension is semi-independent, interconnected by means of a torsion beam.VIEW OF REAR SUSPENSION (VARIANT WITH DISC BRAKES)1. Axle2. Shock absorber3. Shock absorber mounting4. Spring5.

Brake drumThe improvement of the torsion profile and the increased strength of the brackets has made it possible to produce better structural rigidity also reducing the overall weight.The particular conformation of the torsion profile (with different thicknesses depending on the version) has made it possible to produce excellent stabilizing strength without the need for an anti-roll bar.The vertical arrangement of the shock absorbers with the bodyshell mounting inside the wheel arch has resulted in excellent filtering of uneveness from the road surface with benefits in terms of noise levels in the passenger compartment.

Care should be taken not to mix up the left and right rear turret mountings. With this in mind, the right mounting only has an opening (1) in the position illustrated in the diagram.

The structure of the axle comprises side arms pressed in two half shells secured to a side torsion profile with the ends of the actual arms being cylindrical in shape.The axle mounting bushes guarantee flexibility for the suspension under an increased longitudinal load, whilst the special shape of the buffers ensures prompt dynamic responsiveness when cornering. The bushes are fitted at 2400 kg on the arms at an angle of 25°.

The fitting of the rear springs (1) involves the angular position of the spring, produced by matching the flat surfaces of the lower support ring (2) and the duct (3) secured to the axle.
